At the 2007 Society for Information Display conference in Long Beach, CA SeeReal, a German firm demonstrated a new holographic 3D video display.
The idea here is that the monitor uses an eye tracker to follow your eye's movement. It then displays a 30 X 30 pixel image that contains the complete image, a separate view for both right and left eye. This would reduce the huge amount of data normally needed for stereoscopic display.
Its only in prototype phase now and the images it displays are in red tones, not full color, as the image they provide clearly shows.
Would you be happy with 1,800 pixels of resolution? How effective is the eye tracking software? What if I had an epileptic seizure? How soon do they project being able to do this in three channels of full color?
