Quick, define the word "skinput"

Is this what you guessed?

I'm a technology geek, and I love this stuff.  I would really enjoy working in a lab to design and test this stuff.

So...  Your next mobile device may be worn strapped to your upper arm and have no screen other than the pico projector that beams an interface onto your arm or hand.

My only concern is how well it does with clothes under the receiver on your arm, or on your lower arm.  Or gloves, for that matter.

The projector and camera setup is significantly more flexible (gloves are ok), but not nearly as accurate.
