As much as I would love toying with this, it really all about implementation.

There are a lot of issues to consider - what if I mean to swipe one thing but the system recognizes another? how is that handled? Does it calculate the position of my head and the perspective I'm seeing?

I agree with the above comment that this would ideally be an addition to our growing arsenal of HIDs, including keyboard, mouse, touch mouse, joystick, wacom tablets, and others are not intended to replace one or the other, most of them are complementary to other HIDs.
