Steam Link Touch Controller Guide - A Visual Introduction

This guide will get you started on how to use the Steam Link app's Touch Controller and how to create configs for it.

Introduction

Preface

The first two sections are a brief overview of Steam Link and the Steam Link app's Remote Play Touch Controller along with layouts. If you are already familiar with them, you can skip to Touch Controller in Steam Link to get started.

• This guide is being updated to reflect the new Big Picture Mode.
  
• Warning. This guide is extremely data heavy (about 350 MB of data). To reduce their file sizes, GIFs have reduced visual quality and are sped up.
  
• Presence of visual artifacts in the recordings such as moiré, lack of sharpness, and incorrect color reproduction are due to improper filming on my part.

Before we begin - What is Steam Link?

In case you are not familiar with Steam Link, it can refer to two different things that Valve has created: the Steam Link hardware box sold between 2015 and 2018 (this set-top box is no longer being sold), and the Steam Link app launched in 2018 (available for free on Android, iOS, Raspberry Pi, Windows, Mac, Linux, Samsung Smart TVs, and more).

They both serve the same purpose: games from your computer running Steam can be streamed to and played on a device running the Steam Link app or on the Steam Link hardware, whether both the computer and device are on the same network or on different networks (how well it works between different networks depends on the download and upload speeds along with ping/latency of both networks).

For example, you can locally stream a game from your computer in the living room to your phone running Steam Link in the bedroom by having both devices connected to your router's wireless network, and you can also remotely stream a game from your computer at home to your phone over the internet.

Steam Link and Steam Remote Play allows you to stream computer games from your computer to your device, whether they are both on the same network or over the internet.

There are no fees for streaming; the only things you pay for are the games that you buy for your Steam account. As a side note, you are also able to stream between computers using the Steam client.

The focus of this guide will be on the Touch Controller in the Steam Link app on Android and iOS.

Showcase

During the GIF optimization process, the above clips became slightly distorted; i.e. the joysticks should be circles, not shaped as ovals.

What is the Touch Controller in the Steam Link app and what are layouts?

If you do not have a gamepad connected to your smartphone or tablet, you can play games using the app's on-screen controller called the Remote Play Touch Controller. When you launch a game, the various controls, such as buttons and D-pad, are placed on top of the screen, allowing you to play as though you are using a physical controller. This guide will cover all aspects of creating a layout for the touch controls.

In the Steam client, the Controller Settings, popularly known as Steam Input and formally called Steam Input Configurator (SIC), allows you to customize controls' bindings for any of your controllers, including the Steam Controller, Xbox Core (Series) Controller, PlayStation DualSense Controller, and Nintendo Switch Pro Controller. Likewise, customization is available for the Steam Link app's Touch Controller. These bindings are also called layouts, and you are able to create layouts for each game you have through the Controller Settings. This guide will cover the basics of creating a layout for your bindings.

Since the positions of the touch controls on the screen are collectively called a layout and the custom bindings you make in Controller Settings are also called a layout, to minimize confusion between the two, I will refer to the former as touch layout and the latter as bindings layout.

The combination of the touch layout in the Steam Link app and bindings layout in the Controller Settings in the Steam client is what makes playing PC games on a touch screen device viable.

Note:

• The Remote Play Touch Controller is also available to use on a Windows tablet running the Steam client when streaming from a host computer. To use it, open the Steam client on your tablet (client computer) -> press Steam on the menu bar -> Settings -> Remote Play -> Advanced Client options -> check mark Enable Touch Controls. The next time you stream a game to your tablet, the Touch Controls will appear on your tablet's screen. I recommend starting streams through Big Picture Mode.

For a list of games in the Steam store that have ready-to-use touch controls, refer to Remote Play on Phone and Remote Play on Tablet hubs.

For looking up the current version and patch notes for the app, refer to Steam Link Android Patch Notes. For the hardware, refer to Steam Link Hardware Patch Notes as well as the pinned topic in the General Discussions sub forum.

Remote Play Touch Controller

When you launch the Steam Link app, it will look like the following:
The bottom row of icons are quick links to games that you have recently played. Pressing any of these will launch the app directly into that game.

If you have a physical controller connected to your smartphone/tablet, either disconnect it or go into Settings -> Controller -> and select Touch Controller. Your active controller will now be the on-screen Touch Controller. Press Start Playing.

After the app has connected to your computer and finished loading, you will encounter (New) Big Picture Mode (BPM), which is the alternate interface of the Steam client, and the touch controls for BPM will appear.

Controls on the screen:

1. Steam Link's Tray: Access the Touch Controller and Mouse settings.
   
2. Touch Controller's Guide button: When you are in a game, press this to bring up the Steam Overlay.
   
3. Keyboard: Toggles your phone's keyboard for typing input. Note that the position of this button should be above your phone's keyboard so it can be conveniently pressed again to hide it.
   
4. D-pad
   
5. Button pad

Notes:

• You can also launch the app into the main menu of Big Picture Mode or your desktop by going to the main menu of Steam Link -> enter Settings via the cog icon at the top-right corner -> Streaming -> Advanced -> and then choosing between the three options under Start Streaming: Recent games (default and currently the same as Big Picture), Big Picture (main menu of Big Picture Mode), and Desktop.
  
• If you are sitting next to the computer running Steam, note that the controls do not show on your computer's monitor.
  
• If your desktop's resolution is set to 16:9 ratio and you stream it to a device with a screen that is not 16:9, you will get black bars along the left and right (if your device's screen is wider) or along the top and bottom (if your device's screen is taller) sides of the screen.
  
• By default, if you do not touch your device's screen for 10 seconds, the controls will fade away. Touching the screen again will bring them back. This can be changed via the Steam Link menu icon [...] at the top-left.

Before moving on, to stop streaming press the Steam Guide button -> Power -> Stop Streaming. This will disconnect the app from your computer. You can also choose Exit Steam, but that means that Steam will quit on your computer and you will not be able to stream again until you go to your computer and launch Steam.

Note

• If you minimize the app, back out of it on your device, or turn off your phone's display, the app will stop streaming after a few minutes. If you disconnect or lose connection while a game is running, you can resume playing by starting the stream again.

For now, explore Big Picture Mode with the D-pad and Button pad.

When you are done, go into your Library, pick out a game, and launch it.

When the game starts, various touch controls will appear.

If there are no recommended layouts available for the Remote Play Touch Controller, Steam will load a layout from the most similar controller type. For games that have controller support, the layout used is the Gamepad template; otherwise it will be the Keyboard (WASD) and Mouse template.

While you are in the game's main menu, let us take a look at Steam Link Tray [...].

Presented are the different mouse and touch controller modes that you control your game with. So actually, the Steam Link Touch Controller I have been referring to so far is composed of these two parts.

Mouse - Part 1

Mouse Modes

The large button on the right side allows you to switch between different Mouse modes, and below it is the gesture list for that mouse mode that includes the various gestures you can do and their corresponding actions. When you touch anywhere on the screen that is not a control, you can control the cursor, and it will move and behave based on your fingers' movements and the mode you have chosen. There are four options: Trackpad, Trackpad Cursor, Direct Cursor, and Disabled.

Trackpad

Mouse input is the same as controlling a cursor with a laptop's trackpad; moving your finger across the screen will move the cursor as well.



The gestures are as follows:

• Move: 1-finger slide
  
• Left Click: 1-finger tap
  
• Drag: 1-finger hold
  
• Right-click: 2-finger tap
  
• Zoom/Pan: 2-finger pinch/slide (when enabled)
  
• Keyboard: 3-finger tap
  
• Steam: 4-finger tap

Trackpad Cursor
Like Trackpad, mouse input is the same as moving it on a laptop's trackpad. Although it may appear to behave the same as Trackpad, there are a few differences.

• Trackpad provides relative mouse motion to the game while Trackpad Cursor provides absolute mouse position to the game.
  
• The mouse cursor in Trackpad Cursor will stay in view while moving the cursor around when zoomed in (by zoom gesture); it does not in Trackpad.
  
• In some games, the cursor will be extremely sensitive when using Trackpad Cursor.

The gestures are the same as those for Trackpad.

Direct Cursor
Wherever you touch the screen, the cursor will move to that position. Similar to Trackpad Cursor, the cursor can exhibit extreme sensitivity in some games.


The gestures are as follows:

• Left Click: 1-finger tap
  
• Right-click: 2-finger tap
  
• Zoom/Pan: 2-finger pinch/slide (when enabled)
  
• Keyboard: 3-finger tap
  
• Steam: 4-finger tap

Disabled
Disables the mouse.







Note:

• Your fingers do not have to be close together when invoking gestures that require multiple fingers. For example, you can tap the opposite sides of the screen with your thumbs to invoke the right-click gesture.

Mouse - Part 2

Mouse Options

These options will also change how your cursor behaves, and any changes to these are saved specifically to the config you are currently using.


Gesture: Zoom/Pan screen
Pressing this toggles the pinch-to-zoom gesture. By turning on this option, you can magnify the screen by performing a pinch-to-zoom gesture and then pan the screen afterwards with two fingers. The stream will snap back to place when you resize it back to its original size and center it. This gesture does not work if you have mouse mode disabled.


Additionally, if you have zoomed or panned the screen and then toggle off the gesture, the screen is locked in place.



Trackpad Cursor Speed
This option changes the cursor speed of Trackpad and Trackpad Cursor. The default speed shows two cursor icons.




Hide Cursor at game launch
Pressing this will hide the cursor at the bottom-right corner of the screen. This is useful for when you are using gamepad controls to play a game but the game does not automatically hide the cursor.

Extra Topics

Gesture: Right-click drag
The right-click drag is not listed in the Trackpad and Trackpad Cursor gesture lists, but it is available. As stated in the lists, to left-click drag you place a finger on the screen and hold it there.
Then drag your finger across the screen.


To perform right-click drag, begin by performing the left-click drag. Then use a different finger and tap the screen. The left-click drag now transitions into a right-click drag.


You can perform the gesture much quicker than in the above, to the point where the left-click drag is skipped directly to the right-click drag.


For the right-click drag to work properly, the second finger that touches the screen should also be the one you lift off the screen or else the gesture will trigger right-click being held down but the cursor can not be moved. This can easily happen if you are performing the gesture quickly and not being careful about the order of finger contact and liftoff.

Touch Controller - Part 1

Touch Controller Modes

Enabled

When enabled, you can place controls onto the screen through Layout Controls. These controls give you access to gamepad buttons, keyboard keys, and other Behaviors from Controller Settings.



Disabled
Disables the controller, including the Guide button.

Layout Controls

Press Layout Controls. These controls are used to build a layout.

1. Guide button
   
2. Start
   
3. Back
   
4. Shoulder buttons
   
5. Trigger buttons
   
6. D-pad
   
7. Button pad
   
8. Touchpad (Unified/Split)
   
9. Joysticks
   
10. Joysticks buttons
    
11. M1 - M8 buttons (Macro buttons)
    
12. Keyboard
    
13. Magnifying Glass
    
14. Controls' Color and Transparency
    
15. Inspection Tool

Note:

• Controls that are grayed out in Layout Controls cannot be placed and will appear as standard controller buttons. To use them, they must be assigned some Behaviors in the Controller Settings.
  
• Controls that have been assigned in Controller Settings and have not placed onto the screen will vibrate in Layout Controls.
  
• Joystick buttons can only be placed when the joysticks are set to a Behavior in Controller Settings and the buttons are set in Click Action.
  
• When a control is touched in Edit Mode, its outline will turn green, indicating that it is the active control to be adjusted.

Things you can do to a control

There are three main actions you can do to a control: position, scale, and remove.

Position

Hold then drag a control off of Layout Controls, upon which the tray will close, and place it anywhere on the screen. The transparent blue color indicates that you are in Edit mode and touching empty space will not trigger the mouse if it is enabled.


Grouped Controls
Some controls move off as a group from Layout Controls. Once placed, the individual controls can be repositioned.

• Guide, Start, Back
  
• Button Pad
  
• Split Trackpad

Overlapping Controls
When controls overlap in Edit mode, their outlines become red. The app does not prevent you from overlapping them.


Reposition
Controls can be repositioned in two ways: move them in Edit Mode or drag the control again from Layout Controls.


Select multiple controls simultaneously
Multiple controls can be selected at a time in Edit mode by touching an empty spot and moving your finger diagonally over them, creating a box.


Deselect
Controls can be deselected by either selecting another control(s) or performing select multiple controls over empty space.

Scale

Controls can be made larger and smaller in Edit mode. Resize by touching the control and using another finger to pinch in or out. You can also place your fingers in unused space to resize after you touch and highlight it.

Remove

Controls can be removed from the screen. When you move controls in Edit mode, the Steam Link Tray [...] icon turns into a trashcan. Release the control(s) over the trashcan to remove them. They can be placed again from Edit Layout.

Organizing your controls

To help organize your controls, there are three main ways: alignment guide lines, snap, and color and transparency.

Alignment Guide Lines

When dragging a control, yellow alignment guidelines will appear from its center as horizontal and vertical lines. Dragging it into another control will cause that to emit blue guidelines.

Snap

Controls will snap to certain positions and/or sizes for various reasons:

Previous position and size
When a control is placed and saved in Layout Controls, the app will remember its position and size. The next time you move it, a grey ghost/outline of the control will remain at its original position. When moved close to it, the control will snap to that original position and size.


Snap to alignment guide lines
When a control is dragged through another, the other control will emit blue guidelines. Moving the control close to the blue guidelines will cause it to snap to the lines.



Controls of the same type
Controls of the same type will snap to each other if their axes are close enough or they are close to some set horizontal distance.

Control Type	Vertical Axis	Horizontal Axis	Horizontal Distance
Shoulder buttons		✔	✔
Trigger buttons		✔	✔
Joysticks		✔	✔
Macro buttons	✔	✔

Predefined positions
The Steam Link tray menu, keyboard, and magnifying glass have predefined positions on the screen that they can snap to.

• Steam Link tray menu: all four corners.
  
• Keyboard: top-left and top-right corners.
  
• Magnifying Glass: top-right corner, below the keyboard's predefined position.

Override control snap
To get around snapping in Edit mode, first let that control snap to where it wants. Then move it a small distance to where you want to place it. It will not snap unless you move it far away and back again.

Color and Transparency

The color and transparency of the controls' outlines can be adjusted via the colored wheel at the top-right corner of Layout Controls.

Touch Controller - Part 2

Touch Controller Options

These options will also change how your controller and layout behaves, and any changes to these settings will apply globally to any games you play.


Gyroscope
Toggling this will turn on/off the gyro. Note that in addition to this gyroscope option, the layout in Controller Settings also has a binding for gyro. If nothing is bound to it, such as Mouse used to control the mouse cursor, then attempting to use the gyro will have no effect, even when it is enabled in the app.



Rumble
Pressing this will turn on/off controller vibration.






Touch Controls Visibility
This option determines the visibility of the touch controls:

• Hide the controls after 10 seconds.
  
  
  
  
  
  
  
• Always show the controls.
  
  
  
  
  
  
  
• Toggle between always showing or always hiding the controls (including the Steam Link tray menu) by shaking the phone.

Extra topics

Copy/Paste and Reset Layout
In Layout Controls, access Copy, Paste, and Reset Layout via the ellipsis at the top-left corner.

• Press Copy Layout in one layout and Paste Layout in another layout that belongs to a different Action Layer or Action Set (discussed in Controller Settings Basics) when you want to reuse the same layout. This is particularly helpful if you wish to keep consistent layouts of your controls.
  
• Press Reset Layout when you no longer want your current layout but want some controls in standard positions. The layout will be replaced by the same one you see in Big Picture Mode.

Magnifying Glass
After placing this control on the screen, pressing it will apply a magnifying glass effect on a rectangular region of the screen and pressing it again will turn it off. The magnified region can be moved by dragging it around with you finger. Additionally, a pinch-to-zoom gesture can be applied to it to zoom the image in and out (the pinch-to-zoom option for Mouse mode does not need to be enabled for this effect to take place).


Note: The magnifying glass will follow the cursor, including when moving the cursor using any of the mouse modes.

Inspection Tool
Drag the inspection tool over the controls in Layout Controls to see their bindings or assigned names.


Statically and dynamically placed Joysticks
Unlike other controls, the joysticks can be placed in two ways: statically placed and dynamically placed.

Statically placed is the same you do to any control that you want to use. After enabling them through Controller Settings, place them on the screen from Layout Controls.


Dynamically placed does not require you to place the joysticks onto the screen in order to use them, but Mouse mode must be disabled in the app. After enabling the joysticks through Controller Settings, return to the game. The left and right joysticks will appear beneath your fingers anytime you touch the left half and right half of the screen, respectively.


Difference between D-pad and Joystick
Besides how they appear on the screen, they behave a bit differently.

For D-pad, if you place your thumb on it, such as pressing Up, and then move your thumb away, the D-pad will stop receiving your command.

For joystick, if you place your thumb on it and press up, you can keep moving your thumb away from the area of the joystick and it will still receive your command.


Visual Feedback
The following includes topics on Controller Settings that are described in more detail later in the Controller Settings sections.

Toggle in an activator
When a control that has Toggle enabled in the activator is pressed, it will appear on the screen as being held down, or opaque. Pressing it again will turn off the control.

Long Press and Double Press activators
For controls with bindings that use the Long Press and/or Double Press activators, they will appear on the screen with additional indicators next to them.

A control that has a Long Press activator will have a line next to it.

• If this control also has a Regular Press activator, tapping it will cause the Regular Press activator to be triggered.
  
• When the control is held down, the line will fill up over time. After a certain amount of time, the duration of which is set through Controller Settings, the bar will be filled and the Long Press activator will be triggered.
  
• If the control is released before the line is filled, the line will immediately reset to being empty.

A control that has a Double Press activator will have two dots next to it.

• When the control is pressed once, the first dot will become larger.
  
• If the control is pressed again within a certain amount of time, the duration of which is set through Controller Settings, the second dot will also become larger and the Double Press activator will be triggered.
  
• If the control is not pressed again within a certain amount of time, the dots will reset to their original size. And if the control also has Regular Press activator, this will be triggered.

Note that for a control that has a Long Press and a Double Press activator, only the double dots indicator will be shown but holding down the button will cause a growing line to appear.

Saving Layouts

Layouts that you create in the app are unique to each game. When you save a bindings layout in Controller Settings, the touch layouts of your controls, and mouse mode are recorded along with it. Saving a layout will be covered in the next section.

Controller Settings

Now that you know how to create a layout for the touch controls, how do you change what the controls do? For example, how to make the [A] button on the Touch Controller act like the {Z} key on a keyboard? That is where Controller Settings steps in.

All of the controls that you can place from Layout Controls in the Steam Link app correspond to Input Sources in Controller Settings. So any changes you make there will modify how your controls behave in-game.

The behavior of each control that you see in Layout Controls in the Steam Link app can be modified through Controller Settings in the Steam client.

From here, I will be guiding you on the basics of the Controller Settings to get you started on creating a config for the Remote Play Touch Controller. Covering all aspects of it would be too overwhelming for this guide and much of it has already been explained well elsewhere.

Information on the SIC can be found in the Steamworks Documentation on Steam Input. Here are a few links from it to get you started:

1. Steam Input - General Concepts
   This will cover what the Steam Input Configurator is and explains how it works.
   
2. Steam Input - Input Sources
   This expands a bit more on what Input Sources are (fairly straight-forward but necessary to understand for the next link).
   
3. Steam Input - Input Source Modes
   A reference on the various behaviors of the Input Mode Sources, which change how certain Input Sources behave. While most of them are easy to understand, figuring out what some of their settings do can be a bit difficult. Use this link when there is something you do not understand.

Alternatively, I have covered all aspects in my other guide
https://steamcommunity.com/sharedfiles/filedetails/?id=2804823261
Although this was written with Steam Deck in mind, it predominately walks through major parts of Controller Settings (in new Big Picture Mode) and its contents is just as applicable here. That said, this guide will cover settings that are uniquely available for the Touch Controller in a later chapter.

Accessing Controller Settings

There are a few ways to reach Controller Settings; here are the two that you are likely to use with the Touch Controller:

1. While in-game, press the Guide button -> Controller Settings.
   
2. While in Big Picture Mode, navigate to your game in the library -> Manage Game -> Controller Settings.

That being said, you will likely use the first way since creating a config usually involves going back in forth between editing the layout in Edit mode in the app and changing the input sources in Controller Settings until you are satisfied.

Note

• Steam must detect your controller before it will allow you access to Controller Settings.

Enter the Steam Overlay and note what your layout is now. If you had modified the layout while you were in the game, it will be different from the layout you see in Steam Overlay. Now go to Layout Controls.

Notice again that the controls available here are different from the controls that you had in-game. That is because Steam can contextually change controls and layout depending on what screen you are in. Making adjustments now in Steam Overlay will modify the controls and layout associated with the Steam Overlay.

If you want to make any changes to the layout for a game, be sure you are actually in the game and not in Steam Overlay or Big Picture Mode. Otherwise, you will be modifying the controls for the wrong screen.

If developers have implemented the Steam Input API into their games, that means the control layout and bindings for their games can be context sensitive. This is called the Native mode in SIC. For example, a developer can make it so that the controls and layout automatically change when going from the Main Menu, where not that many controls are needed, to in-game play, where you will most likely need all the controls on your controller. However, most games you encounter will not have this implemented. This means you will be using Legacy mode where controls are not context sensitive. While this can be inconvenient, using action sets and action layers in Controller Settings can make this less of a problem.

Notation on Reading the Next Sections

For the following sections, I will be constantly referring to the different parts of the Touch Controller, the bindings in Controller Settings, and the corresponding action in game.

For the sake of clarity, I will be using the following notation in the Controller Settings sections to distinguish which of the three I am talking about.

• [Touch Controller control]
  
  • When enclosed in brackets, this refers to some part of the Touch Controller.
• {Binding}
  
  • When enclosed in parentheses, this refers to a binding in Controller Settings.
• Action
  
  • When capitalized and italicized, this an action in the game.

Some examples:

• [A] is set to {A button}
  
  • When Touch Controller's [A] gamepad button in Steam Link is pressed, the {A button} is triggered in-game. In the case of platformer games, the character would Jump.
• [Right Joystick] has an Outer Binding set to {RT}
  
  • For the case of twin-stick shooters, placing your thumb near the edge of the [Right Joystick] in the game will cause {RT} to be triggered, causing the character to Fire.
• [Start] is set to {Esc key}
  
  • Pressing the Touch Controller's [Start] button in Steam Link will correspondingly press {Esc key} in-game. This will bring up the Pause Menu or Back out of a menu option in most games.
• [M1] is set to {`} (this symbol is tilde)
  
  • When pressing the Touch Controller's [M1] button in Steam Link, {`} will be triggered in the game. For games developed by Valve such as Half-Life and Portal 2, this will bring up the Developer Console, assuming it has been enabled in the game's settings.

Controller Settings - Fundamentals

When you enter Controller Settings, you will be presented with the following:

1. Start
   
2. Back
   
3. Shoulder buttons
   
4. Trigger Buttons
   
5. Digital pad
   
6. Button pad
   
7. Trackpad (Center/Unified)
   
8. Trackpad (Left-Right/Split)
   
9. Joysticks
   
10. Joysticks button
    
11. Macro buttons (M1-M8)
    
12. Always on
    
13. Gyro
    
14. Touchscreen mouse gestures: modifies 1-finger and 2-finger mouse gestures.
    
15. Action Sets
    
16. Action Layers

1 to 14 are Input Sources.

If you feel this layout looks familiar, it is similar to the one for the PlayStation DualShock 4 controller, with the addition of Macro buttons and Touchscreen mouse gestures.

Any control that you change in Controller Settings is reflected in the app, whether that is modifying, adding, or deleting buttons. If you deactivate anything here, the corresponding control will be removed from your layout in-game and become unselectable in Layout Controls.

Input Sources and their Input Source Modes

The Input Sources have access to the following Input Source Modes:

Input Sources	D-pad	Button Pad	Mouse	Mouse Joystick	Joystick Move	Joystick Camera	Joystick Mouse	Scroll Wheel	Mouse Region	Touch Menu	Radial Menu	Single Button
Digital pad	✔	✔			✔		✔	✔	✔		✔
Button pad	✔	✔			✔		✔	✔	✔		✔
Joysticks	✔	✔			✔		✔	✔	✔		✔
Trackpad	✔	✔	✔	✔	✔	✔		✔	✔	✔	✔	✔
Gyro	✔		✔	✔	✔	✔			✔

Switch (Start, Back, Shoulder buttons, Macro buttons, Always On, Touchscreen mouse gestures) are simple digital buttons. While Trigger buttons can have analog values, they behave like simple digital buttons in the Touch Controller.

The Input Source Modes are listed under Style of Input within each Input Source in Controller Settings, and I will refer to Input Source Modes and Style of Input synonymously.

Explore and change the various options to see how the controls behave within the game. You can set the Touch Controller to use gamepad input, keyboard input, or a mixture of both. Remember that there is a link above that can explain what the various options do in case you are unsure.

Note:

• The Center and Left/Right Trackpads are available for editing, but only Center or Left/Right can be placed in the app, not both.
  
• Anything assigned to Always On in an action set will stay active until the user changes to another action set.
  
• The shape of controls in-game do not change regardless of which input source modes you choose to assign to them in Controller Settings. For example, the D-pad set to use Radial Menu will still appear as a D-pad in the app but it will behave as a Radial Menu.
  
• There are games that do not react well to mixing gamepad input and keyboard input. In particular, the in-game button prompts may immediately switch between gamepad and keyboard/mouse, depending on the detected input, or the games may entirely disable one of the inputs. You will have to test this out if you plan to mix them together.

Activators

You can access advanced settings for a binding by pressing the Activators button at the bottom.

This reveals the different activation types which change how the button behaves:

• Regular Press - This is the default choice whenever you make a binding.
  
• Double Press - Press a button twice within the Double Tap Time to trigger this binding.
  
• Long Press - Hold a button for the duration of Long Press Time to trigger this binding.
  
• Start Press - This binding triggers the moment you press the button.
  
• Release Press - This binding triggers after you release the button.

You can have multiple Activators assigned to a button.

Fire Start Delay and Fire End Delay affect when a button is triggered and for how long it will be held down. When a button with multiple activators is pressed, the timers for these settings begin simultaneously.

Action Sets and Action Layers

An action set is a group of bindings with an associated layout in Controller Settings. When you begin editing a new config, that is what you are editing. You can add more sets and switch between them while playing. Because each set has its own layout, you will have to make a different layout for each one in the app.

One way action sets become useful is if a game has multiple states and the controls in one state share little in common with the controls in another state. For example, controlling a character on foot and driving a vehicle in an open world game can have very different controls. Therefore, you can create one action set for running around and another for driving, and switch between the two as needed. Another example is when the game has access to special menus such as the developer console, it can be useful to place them into a separate action set.



An action layer is similar to an action set, except it exists within an action set and only contains whatever input sources that you have added or changed to its parent action set. Another difference is that multiple layers can be active at once. Each layer that you apply in a set during gameplay is stacked at the top of all layers so that whatever buttons the top layer contains will override the corresponding buttons in the layers below them, similar to layers in a photo/image editing software. A good explanation and example of action layers can be found at Steamworks Documentation - Action Set Layers. Any layer added during gameplay can also be removed.

When you add or modify any input source in an action layer, you can also adjust those controls' positions in the layout. For the buttons that you do not change, any attempts to move their positions in the layer's layout will not be saved by the app; they will remain at their original positions associated with the action set.

Because action sets and action layers also contain layouts in Steam Link, they can also be used to simply move controls about your screen. For example, in 2D side scrolling beat 'em ups, enemies usually come from the lower right side of the screen. If your button pad is located there, then the buttons and your fingers pressing them can block your vision from seeing enemies coming. You can create an action set or layer to move the buttons around as needed while playing.

Switching between Action Sets and Action Layers

To switch between action sets and action layers in the game, you should set an input source to change it and place it on the screen. It is the first button in the Special Inputs row (highlighted in green below).

Note:
When switching between action sets, the following will happen:

• All applied action layers from the previous state will be removed.
  
• All buttons that are toggled on will be toggled off.

Controller Settings - Basics - Part 1

Here I will be going through the parts of Controller Settings that I frequently use.

Assigning a binding to a button

For [Start], [Back], [Shoulder buttons], [Macro buttons], [Always On], [Touchscreen mouse gestures], they are simple digital buttons. After selecting one of them, you can choose which gamepad input, keyboard key, or mouse button you would like to assign.

For example, modify the [M1] button to be the {A gamepad} button in Controller Settings. Now return to the game and go to Layout Controls. The [M1] button that was previously grayed out will now be available for you to position. Place it on the screen and leave Layout Controls. Press the new [M1] button and note that it now acts as an {A} button.



For the [Triggers], you can also do the same, but note that there are two places that you assign them: Full Pull Action and Soft Pull Action. While having the two options is useful for physical gamepads, for the case of the Touch Controller, the [Triggers] appear as buttons on the screen so the only thing you can do is press them. In that case, you can assign bindings to either Soft Pull Action or Full Pull Action. If you are binding keyboard keys, I recommend setting Trigger Analog Output to Off, or else the corresponding button in game may not react properly.

For each binding, you can also assign an icon which will appear in the app.

Joysticks

When you enter either [Joysticks], a Style of Input will appear on the left. Selecting it will present the various Input Source Modes in a drop-down menu. Your choice here will change how the joystick behaves.

Note that in order to use [Joystick buttons] in game, one of the Style of Inputs must be selected. In each one, there is an entry called Click Action, and setting a binding here will make available [Joystick buttons] in the app.

• If you assign a button in one Style of Input but decide to use another, the binding in Click Action from the first is not transferred to the second, so it must be set again.
  
• There are other places in Controller Settings that have Click Action entries, but those do not have a corresponding button in the Touch Controller. Only the Click Action entries in the [Joysticks] have buttons in the app.

Here are the Input Source Modes I commonly use.

• Directional Pad
  
• Joystick Move
  
• Radial Menu

Directional Pad

This allows you to set bindings for the cardinal directions of the [Joysticks]. This is useful for games where you plan on using keyboard bindings. For example

• When using Directional Pad for the [Left Joystick], I can set the cardinal directions to be {WASD} for moving a character in a first/third-person game.
  
• The same bindings, or the keyboard's arrow keys, are also commonly used for controlling the top-down camera in isometric games.

Joystick Move

First, note that the Output can be set to {Right Joystick}, {Left Joystick], or {Relative Mouse}. This also affects what the [Joystick] does.

• By default, the Touch Controller's [Left Joystick] is set to output gamepad's {Left Joystick} and the Touch Controller's [Right Joystick] is set to output gamepad's {Right Joystick}. This is what you would use when you want to use the [Joysticks] as the gamepad's {Joysticks}, assuming the game has controller support.
  
• {Relative Mouse} is useful when you want to control the mouse cursor in-game while using a joystick behavior. So the further you push the [Joystick] the faster the cursor will move.

Radial Menu

Some games have many keyboard shortcuts, most of which can be useful. However, placing all of them on the screen might not be practical because they may end up obstructing your view of the game. In that case, you can place buttons in the Radial Menu, particularly into each Menu Button. When placed on the screen, placing your finger on the [Right Joystick] will show the items in the menu. To use less space on the screen, you can resize [Right Joystick] to be even smaller.



For Menu Activation Style, it should be set to either Touch Release/Modeshift End or Always. By default, the [Joysticks] use the former.

• Touch Release/Modeshift End - When you move your finger over a menu item and then lift your finger, the menu item is triggered.
  
• Always - When you move your finger over a menu item, the corresponding action is immediately held down and stays so until you lift your finger.
  
• Button Click and Button Release - These work only on physical gamepads, so do not use these for the Touch Controller.

The first menu option is always located as the top option in the Radial Menu in the game. The positioning of the rest of the menu items depends on how many have been bound. Some examples:

• 2 Menu Buttons - Top and bottom positions.
  
• 4 Menu Buttons - Cardinal positions. The order for Button 1, 2, 3, and 4, are located at the top, right, left, and bottom positions.
  
• 8 Menu Buttons - Cardinal and diagional positions. The order for Button 1, 2, 3, 4, etc. are located at the top, top-right, right, bottom-right positions, etc.

When Center/Unselected Button is bound, it will appear at the center of the Radial Menu.

To change the location of where the Radial Menu appears on the screen, adjust the following two settings:

• On-Screen Horizontal Position - With a range of 0 to 1, 0 corresponds to the top edge of your screen and 1 to the bottom.
  
• On-Screen Vertical Position - With a range of 0 to 1, 0 corresponds to the left edge of your screen and 1 to the right.

Notes:

• Display Binding Label on the Button can be toggled.
  
• Note that the Radial Menu that appears in Steam Link will also appear on your host computer.

Controller Settings - Basics - Part 2

Digital Pad

Just like for [Joysticks], when you enter the [Digital Pad], which I'll also refer to as [D-Pad], there's a Style of Input on the left. For this setting, I primarily use Directional Pad.

Directional Pad

This works the same way as it does for the [Joysticks].

The setting I'll emphasize this time is Layout.

• 8 Way (Overlap)
  
  • This is useful when you need two of the cardinal directions to activate simultaneously. For example, if you bound {W key} to [D-Pad Up] and {A key} to [D-Pad Left], you're able to press [D-Pad Up] and [D-Pad Left] at the same time to move diagonally left in a first/third-person game.
• 4 Way (No Overlap)
  
  • This is useful when you do not need any of the cardinal directions to activate simultaneously. For example, if the game you're playing has four keyboard shortcuts for accessing four different menus, then you don't need any of them to activate at the same time.

Button Pad

Under the Style of Input, I primarily use Button Pad.

Button Pad

This one is self-explanatory. Once selected, you can assign bindings as usual.

Trackpads

There are three trackpads available: [Split Trackpads], which I'll also call [Left Trackpad] and [Right Trackpad], and the [Unified Trackpad], which I'll call [Center Trackpad]. You can only place either the [Split Trackpads] or the [Centered Trackpad] in Steam Link. The app doesn't allow you to place both.

In practice, the [Trackpads] are very similar to [Joysticks], the difference being some of the Input Source Modes they can access.

Here are the Style of Inputs I commonly use.

• Mouse
  
• Joystick Move
  
• Touch Menu
  
• Radial Menu

Mouse

I use this mainly for the Activator's Attach Trackpad/Analog Stick. By attaching a Trackpad to a button, I can press that button, triggering whatever binding it has, and control the cursor at the same time. This is explained in more detail in Controller Settings - Touch Controller Specific.

Joystick Move

I use Joystick Move in [Trackpad] for the same reason as I use Mouse. I can attach [Joysticks] that uses Joystick Move to a button, so that when I press a button I can control the {Joysticks} at the same time.

Touch Menu

Similar to Radial Menu, this allows you to place multiple items into a menu. The main difference between the two is the arrangement of the buttons.



Note that Touch Menu does not work for [Center Trackpad].

Radial Menu

This works the same way as it does for Radial Menu for the [Joysticks].



Note that Touch Menu does not work for [Center Trackpad].

Controller Settings - Touch Controller Specific

There are a couple of settings in Controller Settings that are unique to the Steam Link Touch Controller.

Touchscreen Mouse Gestures

For each of the mouse modes, the default gestures for 1-finger and 2-finger gestures can be overridden by changing the [1-finger] and [2-finger] bindings. And just like other bindings, this has access to Activators as well.


This can be useful when you want to change how a game is played on a touchscreen device or to resolve clicking issues.

• For the former case, some platform shooters require the player to aim the weapon first by holding {Right Mouse Button} before a weapon can be shot via {Left Mouse Button}. This feels fine when using a mouse, but it can feel unnatural on a touchscreen device to have to aim a weapon first before firing. Instead, rebind [1-finger] to {Right Mouse Button + Left Mouse Button} via Multi-Button. This way the player can shoot immediately upon touching the screen.
  
• There are some games where tapping the screen is not registered as a left-click gesture. Instead, the player has to press the screen for a bit longer before the game detects the left-click. As to why this occurs, I am unsure, but one way to resolve this is to set [1-finger] gesture to {Left Mouse Button} and then go into Activators to set Fire Delay End to a longer duration, such as 0.1 seconds (4 ticks).

Activate Analog Stick/Trackpad

For each binding, you can attach any of the [Trackpads] and [Joysticks]. This option is found under Activators as Activate Analog Stick/Trackpad. When you press the button with the [Joystick] or [Trackpad], the binding will be triggered and whatever Input Source Mode is being used for the [Joystick] or [Trackpad] will be invoked. The circle, square, or rectangle that appears around the button is an indicator that a [Joystick], [Left/Right Trackpad], or [Center Trackpad] is being invoked, respectively.


As an example of how to use this, for a first/third-person platformer game that you are planning on using gamepad bindings for:

1. Set [A] to be {A} so the character can Jump.
   
2. Go into Activators and set Activate Trackpad/Analog Sticks to [Right Joystick].
   
3. Go back to the top level and then into the [Right Joystick]
   
4. Set Style of Input to Joystick Move with {Right Joystick} as Output.

Now you can Jump in-game and control the [Right Joystick] at the same time, allowing you to adjust your camera during a jump.



In this case, I had set Activate Analog Stick/Trackpad to [Center Trackpad]. Notice when I press [A] to Jump, the [Center Trackpad] with Mouse appears, represented as a rectangle, allowing me to control the camera while holding the button.

Note that the [Trackpads] and [Joysticks] can be set to use any Style of Input (as an exception, Radial Menu and Touch Menu do not work with [Center Trackpad]). For a couple more examples,

For a strategy game where you are planning on using keyboard bindings to access menu shortcuts

1. Set [Macro 1] to be {Empty}.
   
2. Go into Activators and set Activate Trackpad/Analog Sticks to [Right Joystick].
   
3. Go back to the top level and then into the [Right Joystick]
   
4. Set Style of Input to Radial Menu.
   
5. Set Menu Activation Style to Touch Release/Modeshift End (or Always depending on what you like).
   
6. Fill in the Menu Items with the keyboard shortcuts you like.

Now when you press [Macro 1], the button itself will not trigger any gamepad or keyboard binding and a Radial Menu will appear, allowing you to move your thumb to select the desired item. Note that to use a Radial/Touch Menu, it is unnecessary to do the above steps, since you can simply place the [Trackpad] or [Joystick] in the layout. The benefit of this method is that a button uses less space on the screen compared to a [Trackpad] or [Joystick]; the smallest size of either one of those is still larger than the default size of a button.



In this case, the game required multi-button presses to cast magic spells, so I decided to set the [Right Trackpad]'s Style of Input to Radial Menu and place the spells in it for easy access. The square control that I accessed on the right is the [Right Trackpad] set to its smallest size. The button on the left that I pressed is a regular button at its default size, and it activates the [Right Trackpad], represented as a square, allowing me to access the Radial Menu and cast spells.

For a first/third person game where you are planning on using gamepad bindings for

1. Go to [Left Joystick] and set it to Joystick Move.
   
2. By default, Output should be {Left Joystick} and Click Action should be {Left Stick Click}, which in this game is used for Sprint.
   
3. Go into Activators for [Left Stick Click] and set Activate Trackpad/Analog Sticks to [Left Joystick].

Now you can Sprint and control the [Left Joystick] at the same time, allowing you to sprint and control the character's direction with a single finger.



In this case, the game did not have controller support. Instead, for the [Left Joystick], I chose Directional Pad under the Style of Input and bound the directions to {WASD}. [Left Stick Click] was set to {Shift}, and I had the control activate the [Left Joystick], represented as a circle, allowing me to hold down [Left Stick Click] to Sprint and simultaneously control my direction of movement.

Activate Analog Stick/Trackpad option is available for three activation types:

• Regular Press
  
• Long Press
  
• Double Press

To achieve the effect of Release Press activation type while controlling a [Joystick] or [Trackpad], you can do the following.

1. Bind {Empty} to the [control] you want to use.
   
2. Go into activators and set to activate a [Joystick] or [Trackpad].
   
3. Add a Release Press activator and set it the {binding} you want.

This allows you to press and hold the [control], control the [Joystick] or [Trackpad], and then trigger the {binding} when you lift your finger.

Export, Browse, and Remove Layouts

Export

When you are satisfied with your configs, you will want to save your work. While Steam will periodically auto-save your configs as Personal Bindings, you can also manually save them.

At the bottom of Controller Settings, go to Export Configs.

Personal
A config can be saved under this category as two types: personal binding and local-only binding file.

Personal Binding
Bindings saved here will be attached to your Steam account. That means that even if you use different phones/tablets and computers, the bindings can be loaded from here.

Local-only
Bindings will be saved as a .vdf files on your computer, which can be opened with any text editor. In the case of Windows, they will be found at

C:\Program Files\Steam\userdata\[your Steam ID]\241100\remote\controller_config\[game's App ID]
(or Program Files (x86))

The game's App ID can be found by going to the game's store page on Steam and it will be in the URL link.

https://store.steampowered.com/app/[game's App ID]/[game's name]/

For example, the store page for Slime Rancher is https://store.steampowered.com/app/433340/Slime_Rancher/, so the App ID is 433340.

Community
If you want to share your config with other Steam users, you can save your config to Community. To upload a config here, you need to play with your config for at least 5 minutes without making any adjustments to the bindings in Controller Settings and without making any adjustments in Layout Controls or Touch Controller/Mouse modes within the Steam Link app. Exporting a config here will also create a personal binding under the Personal section.

Template
If you have a combination of layout and bindings that you are planning on reusing across many games, this is the place you can save your config.

Browse

This is where you can browse configs that you and other people have created.

At the bottom of Controller Settings, go to Browse Configs.

You can import and apply configs that you find here. By default, the Controller Settings will only show configs that are compatible or nearly compatible with the controller you are using. If you press "Show Other Controller Types," then you can see configs for many other controllers, such as the Steam Controller, Xbox One Controller, and DualShock 4 Controller.

Recommended
This is where configs created by developers are located. If the bottom-right corner of the entry includes text that does not state Remote Play Touch Controller, then the config listed was not originally made to be used with the Steam Link's Touch Controller.

Personal
This is where all of your saved configs are located.

Community
Configs that have been shared with the community are found here. Because the Steam Link Touch Controller is young and less well-known, this section will be empty for most games.

Templates
This is where Valve provided templates and all of your saved configs that you intend to reuse are located.

Your Other Games
All personal bindings that you have saved for every game can be found here. In a way the purpose of this category is similar to Templates, with the main difference being that this category will populate over time as you create more bindings and import bindings from the community.

Remove Configs

In both Browse Configs and Export Configs, configs that you have created can be deleted by highlighting their entries and pressing Remove. This applies to both personal bindings and community configs that you have uploaded.

Note

• When you export a config to the community, a corresponding personal binding will be created after some time. Deleting this personal binding will also remove your community config. So if you do not want to remove your community config, be careful of which personal binding you delete.
  
• If you remove a config and it does not disappear, it should be gone after you restart your Steam client.
  
• If you wish to delete a config you exported to the community, but the Delete option is not available (this may happen if you export the config and then immediately try to delete afterwards), try restarting the Steam client. The option should appear.

Touch and Binding Layout Tips

In addition to what has already been mentioned, here is an additional list of tips that should prove useful when creating a layout for the Touch Controller. To understand these tips, I'll be assuming that you are very familiar with the Steam Link app and Controller Settings and that the layout being developed will be shared to the community. Lastly, I design layouts based on the idea that I will be playing on a phone with only my thumbs, so no claw grip.

So here are my tips:

• Before committing to a layout, you should have a rough idea of where to and where not to place controls at, because important game elements can appear on any part of the screen. So the things you will have to be wary of are static and dynamic UI elements as well as gameplay events.
  
• Remember that you can look at the keyboard/gamepad bindings for reference, or look up a manual for older games.
  
• Although controls can be placed anywhere on the screen, often they are placed along the sides. When looking at physical controllers, most buttons on its face are easily reachable by thumbs without too much stretching (the noticeable exceptions being the Start and Back buttons). It is the same for the Touch Controller. On the other hand, if you feel it is more natural to place the buttons elsewhere, please do so. Unfortunately, this can mean that a lot of controls may be crammed along the sides.
  
• Most of the time, I end up choosing Joystick over D-pad for movement, mostly because the Joystick will continue receiving commands if my thumb leaves the circle while the D-pad requires my thumb to be constantly in contact in order to receive commands. (I also find pressing up-right consistently a bit difficult but that might just be me).
  
• Remember that the D-pad can be used for other things besides movement. I often use it to store additional buttons.
  
• Spend some time thinking about whether to use Trackpad or Direct Cursor. Some games provide more information by highlighting in-game objects with the cursor, which Trackpad is suitable for. Additionally, you can control the cursor with both thumbs and comfortably move the cursor to all parts of the screen. On the other hand, Direct Cursor may require stretching of thumbs or fingers, and information that would have been displayed when highlighting UI elements may be missing when selecting them, but the interaction with the game can feel more natural. Basically, this is a balance between information, comfort, and natural interaction.
  
• Unlike physical controllers, there is almost no standard controls placement for the Touch Controller. The only consistent layout is the one that is created after performing Reset Layout in Layout Controls, which is the same as the layout for Big Picture Mode. This layout will always be the same on any particular device. Keep this in mind when building a layout if you are concerned with a standard experience, but do not let it prevent you from making modifications.
  
• It feels natural to place the Guide, Start, and Back buttons at the top-middle of the screen, but that is often where there is important information in-game, such as a compass. So plenty of times I move them off to the sides.
  
• Because of the different aspect ratios of phones, the controls' positions will become "stretched" when making layouts on a phone of one aspect ratio and playing on a phone of another. This is similar to playing a 4:3 video as stretched on a 16:9 screen. Consequences of this appears as follows:
  
  • The button pad where the buttons are positioned as a diamond on a 16:9 screen will be slightly wider on a wider screen (a recent trend in phone screens). Rather then adjusting the individual placements on the button pad, I would recommend leaving them alone. Once again, this goes back to a standard layout from Reset Layout as the consistent thing between devices of different aspect ratios.
    
  • It will be difficult to avoid, many times impossible, placing controls over in-game UI elements. Because of devices' different aspect ratios, the stream feed will be the same (assuming that the player keeps playing on a 16:9 resolution) but the controls that may have previously been placed to avoid UI elements may now be covering them on different phones and tablets.
    
  • I still consider 16:9 screens the standard, so while 18:9 screens grant extra real estate in the form of black bars on the sides, placing buttons there on an 18:9 screen may end up covering UI elements when a player loads up the layout on a 16:9 screen.
• When it is inevitable that controls will overlap important game elements, such as a mini-map, and text for quests, consider adjusting how opaque (or transparent) the controls are to improve readability. This is available in Layout Controls in the Steam Link Tray menu via the colored wheel.
  
• Action Sets and Action Layers in Controller Settings can be used to simply move controls around. Controls being on the screen means your fingers will be covering up parts of the screen while playing. Important events and obstacles can be accidentally hidden under your fingers. Having a button that changes action sets/layers to move controls around can help alleviate this issue. Examples are side-scrolling beat 'em ups and multiplayer games.
  
• Remember that you can scale button sizes. For example, if I use a D-pad to store four additional buttons that are not used frequently, then I will make the D-pad smaller.
  
• If you need to toggle a button, there are two ways: Activators or Always On combined with Action Sets/Layers. The way for activators is self-explanatory when you look at the settings. For Always On, it will keep holding down that button until you switch to another Action Set/Layer. So you can switch between action sets/layers as a way to toggle off and on buttons. A problem can occur when you have another button that has the same command as the toggle. For example, in a 3D game where left-click hold grabs objects and release to let go of objects, if you toggle grab and then press left-click, the object will be released but the toggle will not cancel. To get toggle to work again, it must be turned off and on again. In this case, this can be resolved by binding One-Finger control in Controller Settings to Empty, making tapping the screen do nothing, or you can bind the control to remove the action set/layer upon tapping which then removes the toggle.
  
• If you need to chain commands together, there are two ways: Toggle Multi-Button On and Activators. For Toggle Multi-Button On, just input the buttons in the order that you want (if you input the sequence incorrectly, you will have to remove that button and start over). However, Multi-Button may be too fast for the game. In that case, there's Activator. For the Activator, set your initial button; then add an Activator, set your button, and set the "Fire Start Delay" up 1 tick (0.025). For the second Activator, set the button and then set "Fire Start Delay" up 2 ticks. Repeat this trend for each additional activator and adjust the delay as needed.
  
• With the above point, you can combine chained commands with Radial and Touch Menu. This is seen in clip in the introduction for Castle Crashers. Right Trigger is for beginning a magic spell and additional button are pressed to cast them. I used Multi-Button to store the button combos into a Radial menu. Now I do not have to fuss about holding down the Right Trigger button with a thumb while pressing the other buttons with my other thumb; it can all be done with one thumb.
  
• Even if you do not like like using gyro, consider testing it out and enabling it in Controller Settings. The user can always disable it through the Steam Link tray menu.

Frequently Asked Questions - Steam Link app

Steam Link app

• Do I need a computer to use Steam Link?
  Yes, a computer is used to stream games to your Steam Link.
  
• Does streaming work between networks, such as from home to school or work?
  Yes. When Steam Link (both the hardware and app) first launched, streaming was only possible within a network. It is now possible to stream from your computer to elsewhere.
  
• Does the Steam Link app or Steam Remote Play cost money to stream outside of home?
  No, streaming is free.
  
• Can I stream and do something else on the computer at the same time?
  No, the Steam Link will focus on the active window.
  
• My stream keeps stuttering. How do I make it work better?
  A proper answer needs to account for many different factors, so you will likely need more detailed help. For streaming within your home network, try reading In-Home Streaming Suggested Network Settings and consider asking in the Steam Link discussions. Basically, for a home network you should have a good quality router 5 Ghz (set the WiFi channel to a value not used by your neighbors, preferably 149 or above), and the Wi-Fi cards/chips on both your computer and touchscreen device should be good as well. For between different networks, you will also need good internet connections (upload/download speeds and latency) for both your computer and touchscreen device.
  
• Is there any noticeable lag when playing?
  This again depends on your network and/or internet connection. You can test your latency by observing your computer monitor and touchscreen device side-by-side when playing a game or by going into the app's Setting -> Streaming -> Advanced -> Performance Overlay -> set to Show Details.
  
• When I stream on my tablet or smartphone, I have black bars along the side/top. How do I get rid of this?
  To eliminate the black bars, you will have to change your computer's display resolution in your operating system to an aspect ratio that matches your mobile device. If there is a difference between the aspect ratio of your computer and mobile device, rather than stretching the image, the Steam Link app letterboxes the stream so that the aspect ratio is preserved. This leaves black bars along the sides (left/right if your device is wider; top/bottom if your device is taller).
  
• Can I use my mobile device's microphone to talk in-game when using Steam Link?
  Yes, the app has microphone support. To enable it, in the main menu of the app, go to Settings (cog icon at upper-right corner) -> Streaming -> next to Microphone, press the arrow button so that the text says Enabled.
  
• When I start the stream in Steam Link, my Library does not show me all of the games that I own. How do I get it to show my entire Library?
  By default, starting the stream in Steam Link will show you your recently played games that are Remote Play Optimized. When you are in your Library, you can turn off this filter by unchecking Remote Play Optimized on the right hand side of the screen. Alternatively, you can instead choose to start the stream at the main menu of Big Picture Mode or your Desktop, neither of which have the filter applied. To change this, go to the main menu of Steam Link, enter Settings via the cog icon at the top-right corner -> Streaming -> Advanced -> and then select Big Picture or Desktop under Start Streaming.
  
• Can I play local co-op by streaming to multiple Steam Link devices?
  Yes, it is possible, if the game's Steam store page lists Remote Play Together on the right hand side. After launching the game, open the Steam overlay. There are two ways to invite others to play:
  
  • For inviting those you have friended on Steam, right-click their names in the Friend's list and send an invite. They can accept the invitation from another computer running Steam or on a mobile device using the Steam Chat app on Google Play or Apple App store.
    
  • For inviting those who do not have Steam accounts, you can copy the invite link from the Friends list and send that to anyone you like. Recipients of the invite can join the game by downloading the Steam Link app for their device through the invitation link. A Steam account is not needed to join a game via this method.
  Visit Steam Remote Play for more details.
  
• Can I use the Steam Link app with controllers like the Steam Controller, Xbox One controller, and DualShock 4 controller? Or what about this generic controller I have?
  Controller support varies among the various forms of Steam Link. Refer to the following Steam Support pages for information on supported controllers: Steam Link (hardware), Android, iOS, Raspberry Pi, and Samsung TVs.

Frequently Asked Questions - Remote Play Touch Controller

Remote Play Touch Controller

• How do I modify what the controls in the app do?
  The behavior of all of the buttons that you see in Layout Controls can be changed via Controller Settings in Big Picture Mode, also accessible through Steam Overlay.
  
• Can I change the controls' color and transparency? They are blocking the screen.
  You can change them by going into Layout Controls in the app and pressing the colored wheel at the top-right corner. To go a step further, you can go into Controller Settings, select the buttons you want, and set each one to a blank image (currently located at the bottom of the list of icons).
  
• Can I stop the controls from disappearing when I do not touch them?
  In the Steam Link tray menu [...], press the button with the icon of a d-pad and four face buttons to change this function.
  
• Can I use my mobile device as simply an additional controller when using Steam Link? I do not need to stream video or audio to it.
  Yes. At the main menu in Steam Link, go to Settings (cog icon at upper-right corner) -> Streaming -> next to Video and Audio, press the arrow buttons until the texts say Disabled.
  
• Can I use my Windows tablet, running the Steam client, as a Touch Controller when streaming from another computer?
  Yes, but first this feature needs to be enabled in the Steam client. In the Steam client on your Windows Tablet (client computer), go to Steam -> Settings -> Remote Play -> Advanced Client Options -> and check mark Enable Touch Controls. I recommend using Big Picture Mode on your tablet when streaming a game. Alternatively, you can use the Steam Link app available for Windows 10.
  
• I loaded a game and it has gyro turned on. How do I turn it off?
  When you loaded up the game, a layout was automatically applied to your Touch Controller which had gyro functionality. An example of this would be Counter-Strike: Global Offensive. To turn it off, open the Steam Link tray menu [...] and press the gyroscope symbol below the Touch Controller button to toggle it on/off.
  
• When using the gyro, I prefer the steering axis to be Roll rather than Yaw. How do I change this?
  Go into Steam Overlay -> Controller Settings-> select the Gyro which is along the middle of the controller -> change Gyro Steering Axis from Yaw to Roll (this option may be under Additional Settings).
  
• I loaded the game before and it had gamepad buttons. Now that I loaded the game, my buttons are now all keyboard buttons. What happened and how do I change it back?
  Not sure what happened but it is possible the game has two layouts designed for gamepad and keyboard/mouse and it applied another. Go into Steam Overlay -> Controller Settings-> Browse Configs -> Recommended and apply a layout from there. If nothing is there, go into either Community or Templates and apply one of them.
  
• When I use the app, the mouse sensitivity is too fast/slow. How do I adjust it?
  Just as you could when playing at your computer, you can adjust the mouse sensitivity by adjusting its corresponding option in-game. Otherwise, there are other ways to change it, depending on which part of the app you are referring to.
  
  • The cursor speed of the app's Trackpad and Trackpad Cursor mode can be changed in the Steam Link Tray menu. There are three speed settings, and the default speed has a picture of two mouse icons.
    
  • If you press a button, see a square/rectangle or circle appear, and move your thumb around and notice that the cursor or camera is too slow/fast, you can change this sensitivity in Controller Settings. First, take a look in Layout Controls to figure out which button it is. Then select the corresponding button in Controller Settingsand look at what option has been chosen under Activate Analog Stick/Trackpad. Select the corresponding [Trackpad] or [Joystick] in Controller Settings, and adjust the Sensitivity.
    
  • If you have enabled Gyro in the app, but you think the cursor or camera is too sensitive or not sensitive enough to your tilting of your device that supports gyro, then go into Controller Settings, select the [Gyro], and adjust the Sensitivity (you may need to adjust the mouse sensitivity in-game if it says so). Additionally, you can adjust the Sensitivity Vertical Scale if you wish for the vertical sensitivity to be different from the horizontal sensitivity. Note that the default steering axis is Yaw, so if you prefer Roll, this can be changed in Gyro Steering Axis.
• When I press a button, a circle, square, or rectangle appears around it. What is that and why does it do that?
  There is a feature in Controller Settings that allows a button to be pressed and simultaneously activate a [Trackpad] or [Joystick], and the circle, square, and rectangle is a visual indicator that this is occurring. When you press a button and see this happen, continue to hold down that button while moving your finger around to see what happens, such as shooting a weapon while controlling the camera. Refer to Controller Settings - Touch Controller Specific for more details.

Misc.

I hope this guide has proven somewhat enlightening. It ended up much longer than I expected and there are still topics that I would like to cover, in particular the Tips section. I'll see if I can do that later, either in this guide or in a separate one.

Also, a couple of months after creating this guide, I started doing contract work for Valve. That said, this guide is not within the scope of my work for Valve and is something I update for fun.

Please bring back the Touch Controller for Windows.

I have also in Steamlink no touch controller. I use a Surface Pro 9.

Tried playing Half Life with the Steam Link app but the touch controls were completely nonsensical and couldn’t be edited.

[quote]The Remote Play Touch Controller is also available to use on a Windows tablet running the Steam client when streaming from a host computer. To use it, open the Steam client on your tablet (client computer) -> press Steam on the menu bar -> Settings -> Remote Play -> Advanced Client options -> check mark Enable Touch Controls. The next time you stream a game to your tablet, the Touch Controls will appear on your tablet's screen. I recommend starting streams through Big Picture Mode.[/quote]

I don't have this option on my Surface Pro 6. Was this removed?

I have a problem with latest build of steam client (update on 2 Feb 2023). Since I update, the gyro of steam link app on android mobile phone did not work, but the steam controller is OK. I don't know whether it is a bug of the latest steam client or the developers remove the gyro function for mobile phone (on the latest steam beta build, the onscreen touch control do not have the gyro function). The gyro of steam link app on android mobile phone is a awesome and convenient function, I can use the phone gyro in FPS game for shooting controll or in ETS2 for steering wheel control without a controller.

The option for touch controls is not in the remote play > advanced client
options settings menu... I'm using win 10 touchscreen device...? am I missing something here? why is there no option? it has only "performance overlay, limit bandwidth to, limit resolution to, speaker configuration, controller overlay button, and a check box for enable hardware decoding" nothing for touch controls... I need the option to be here...

[五更瑠璃]

I don't know why. When I use "direct mouse", the position I click is not consistent with the position where the mouse moves

[819601900]

[protojack]

Idk why but the on screen buttons don't work when I try any game (tried vampire survivors and brawlhalla) But does work on the big screen mode ui, so it's weird?
