Second: Cool, but yes, glasses as displays would be much better but how can you then input information?
same way its currently done. via a camera built into the glasses...
or to be more exact, the setup is like this:
a camera that looks at whats in front of you at all times, looking for 4 brightly colored markers that it knows are your thumbs and index fingers.
a projector with a mirror (the mirror is probably there as the current small projectors are still a bit to bulky to be directed forward rather then downwards), this is the screen.
i suspect the software is set up to go into some kind of suspend mode if it do not see one or more of the markers for a while, where the only thing its doing is to check the camera for said markers ever so often.
when a marker is registered, it either displays a launch interface, or resumes the last task being performed/app used.
then, depending on the number of markers seen, and how they are in relation to each other, as well as depending on what apps currently being run, different input is assumed.
take that paint app for instance, depending on the camera seeing the thumb marker for the same hand, the index finger will be on or off the "paper".
i guess that if one wants to, one can use a ir setup, with transparent caps on the fingers that deal with different wavelengths of ir light, instead of the current color setup (tho it will require a second camera, or forgo the ability to take a picture with a gesture).
if one replace the projector with video glasses, the fingers would be behind the interface, and so would make it a bit more complicated to grasp mentally. but for the system itself, it would be business as usual if the camera placement is correctly aligned with the output of the glasses.
