Why can't mice have a second laser for angle?

[Devsman]

I mean, some mice have like a billion buttons on them so it's not like extending the spec is impossible or anything. Could definitely come in handy.

You're brilliant. I think that rats should have rocket launchers and potato mashers for arms boost.

That doesn't work technically I think, or you would need a special mouse pad. There are air mice however which have a gyroscope, those even work in three dimensions.

Sure it does. The second laser would be just like the first, and it would compare the position of the two lasers to determine the angle.

And what application would this second laser achieve in the end? Isn't it better that people can readjust their mouse in correct position angle as it is now? second laser would prevent that...

Or are you referringn to height angle, not of flat on desk angle? Ok... if height angle, then prob for like pilotiing sumlator... But that require a different pad...

Urg. Headache. Why are you doing this.
I'm being trolled so hard. And I've went for it knowingly.

[Swarmfly]

Would be far too dangerous. Mice already are compelling killing machines as they are with just a single laser!

Several reasons.

YOU might find it handy but it would first increase the difficulkty of use.
The point is they are 2D pointing devices to replicate movememnts on a 2D screen. 3D would be awkward for a start.

But there's also a massive elephant in the room - injury.

Ever heard of carpal tunnel syndrome?

Imagine you invent a mouse that does as you claim and let's also assume that it catches on - guess how many legal cases you'd get from people with injuries due to wrist damage?

You ever wondered why there's so much work into making mice ergonomic? That's why.

So no on several counts.

I'm interested in knowing how you'd manage polling rate for both individually. Sounds like a latency and resource usage heavy solution to a non existent problem.

There was a '3d' infra-red controller for the NES that didn't work as advertised.

Just hook up a PlayStation Move or Xbox Kinect as input device if you want '3d' input

Also, those lasers need short travel distance to the surface in order to reflect differences in surface depth back to a sensor to read for movement.
Having one just firing off with no return feedback because it's not angled properly to be read would result in conflict

Logitech attempted to do that back in 2009 with their "Darkfield" laser sensor.

The mice using that sensor where designed to track on both glass and glossy surfaces better.

Being able to work on see-through glass was impressive, if you just happened to have a glass PC desk table and didn't believe in using a mice pad.

I guess it comes down to the mouse polling rate, which gamers like to be as fast as possible. When there is more than one sensor, they have to work and sync together, which can slow down that rate and therefore the overall speed of mouse to PC updates.

That's fair. Probably the biggest reason.

Well, if polling is a problem, you'd just use more microcontrollers, of course. These things cost nothing and run at millions of instructions per second. So you'd poll for one laser on one uc and the other on another. Hell, they probably have multiple dedicated to the laser of a modern mouse already.

Anyway, I don't care about 3d. I just want to, for example, be able to rotate the mouse in order to rotate the cursor. Imagine in some kind of paint program, for example, being able to define sectors by just clicking and twisting.

Actually, I first got the idea decades ago playing with this Spider-Man Cartoon Maker I had. I was gonna show the Kingpin falling down dead. You normally moved characters by dragging them along the path you wanted them to move. I figured, if I wanted him to fall on his side, I should be able to just turn the mouse so it's sideways. But of course, that didn't work.

Mice in those days had balls inside. But anyway.

Even if the polling problem is insurmountable, it's not like mice would have some obligation to offer this functionality.

Just need a 6DOF mouse like this one:

Weight distribution, power, and miniaturization issues. Anything more than 1 laser and the mouse begins to tire more easily, and has difficulty maneuvering through small spaces and complex terrain.

Oh, okay I get what you mean now.
I thought you meant like being able to pick it up and angle it and have it still read, wasn't really clear in the initial post.

It'd be an interesting concept, and indeed practical for something like rotating 3d model assets.

Rather niche case use though.

Would lol again.

Mouse movement is relative. So it would only be able to detect the change in angle, not the angle itself. For that it would need a gyroscope.
