I do, however, see this tech progressing to other devices and maybe migrating to the front of the phone. If the interface is calibrated well, you could very well have a touch phone with 3D gestures (push/pull/grab/rotate/etc) and you wouldn't need to worry about fingerprints on the screen. Iron man's 3D modeling device, anyone?
What's the point of a mobile device again?
Oh, right. :)
mobile PC eyewear. you're walking around doing whatever it is you want to do, and to access your PC systems reach out in front of you and make gestures. the IR emitted from the glasses reflects and takes note of your hand/finger positions and interprets your actions as interface operations.
far-fetched? maybe i watch too much power rangers
