Plus the constant need for a surface would get annoying, especially in crowded areas.

What i think really needs to be developed is a projector that uses the air alone to project its image. The projector would have to utilize individual molecules in the air to refract the beam on itself. This technology is in the early stages but is far from reality. Also, if one were to develop a screenless projector, it wouldnt be that much harder to then make 3d images (or holograms). By manipulating the depth at which projecter beams come in contact with air particles, the resultant would be a front view 3d image. Essentially, by eliminating the need for a screen, the brightness of the image would stay the same (because distances would be the same) and day to day operation would be less cumbersome.

As for the camera recognition part though, i think its genius and would work great in a necklace. However the controversial privacy issues of always having a camera monitoring your surroundings are monumental.

Yeah, it definitely wouldn't catch on in its current state, but it's still impressive.
