The only question I have is should it appear under IIO or should it be an
input event interface. It feels to me more like an input device in that in
this case while it's not keys or joystick it is still 'please do X'. That
might also make it much easier (in the non-Android space in particular)
to bind these activities to actions in things like web browsers.

(+ linux-input)
