Unity UI Eventsystem navigation events from controller D-Pad

[Rael]

Does anyone know how to allow the Unity UI's navigation event system to be controlled by the Vive controller d-pads? Or how to send navigation events (up, down, etc) to the event system manually via code?

Something like this:

        if (vert > deadZone) // move up
        {
            currentAxis.moveDir = MoveDirection.Up;
            ExecuteEvents.Execute(currentButton, currentAxis, ExecuteEvents.moveHandler);
            waitForZero = true;
        }
        else if (vert < -deadZone) // move down
        {
            currentAxis.moveDir = MoveDirection.Down;
            ExecuteEvents.Execute(currentButton, currentAxis, ExecuteEvents.moveHandler);
            waitForZero = true;
        }
        else if (horiz > deadZone) // move right
        {
            currentAxis.moveDir = MoveDirection.Right;
            ExecuteEvents.Execute(currentButton, currentAxis, ExecuteEvents.moveHandler);
            waitForZero = true;
        }
        else if (horiz < -deadZone) // move left
        {
            currentAxis.moveDir = MoveDirection.Left;
            ExecuteEvents.Execute(currentButton, currentAxis, ExecuteEvents.moveHandler);
            waitForZero = true;
        }

Which is from my xbox-one/x-box360 controller code.
