MIT researchers are developing three-dimensional, holographic displays designed specifically for consumer electronics. The process is actually very cost-effective, making the idea of hand-held holographic technology a viable option for the future. The price point is also decent at $10.
Normally, to produce a holographic image, a laser beam is fired at a target to capture a picture. A photographic plate is hit while the illumination beam reflects off the target. These two beams create a rippling effect on the plate. This scattering pattern (diffraction) creates the 3D illusion. Researchers at MIT are beginning to make this process much more effective.
If you've always wanted to talk to a friend over the phone, but feel like he or she is in the room with you, this could be the next best solution.
Implications - This is revolutionary communication technology.
