Re: Universal Stylus

I haven't read the doc in detail yet, perhaps it also says something about whether or not "hovering eraser<https://github.com/w3c/pointerevents/issues/134>" should be supported as a distinct operation from eraser contact and pen contact while holding an eraser button?


For eraser USI follows the “current standard” - there’s an Invert bit that indicates the tail transducer or erase side switch has been activated to indicate erase mode. Erasing action takes place when the tip is pressed while the Invert bit is set.

Other side switches are reported as they are pressed.

Of course, the system may “muck about” with this - such as the right click functionality on Windows where the OS combines the side switch with the tip switch for right click.
