Next Generation of Holographic Images
suman28 writes "Imagine being able to view an image from all sides and have it interact with you. Scenes or images pop-out at you and change on the fly and are viewable in full color. Best of all, you don't need head-gear or any wearable device to make this possible. They are generated by a computer with two cameras that track your eye movement and there is a transparent LCD screen between you and the display that makes the pictures come alive. Though it may be a while before this becomes part of our daily lives, it is interesting to see what the kind of research being done on this. "
Even though everything is "behind glass", you are still seeing 3D. Afterall, the glass is transparent, it's not like the glass is "producing" the images...
Besides, driving down the street, you will want some *depth* perception. What's funky are those prescription windshields... Try being a passenger in one those cars. You almost need to be stoned/drunk to survive that without a migrain.
There are many different cues that contribute to our perception of depth: stereo, perspective, parallax, overlapping objects, shading and shadows and changes in accommodation and convergence of the eyes.
Those with one eye lack stereo (the strongest cue), but still have a decent amount of depth perception for surviving in the real world. It is only when attempting to use devices that rely soley on stereo to generate a pseudo-3D image that they have problems.
