Your eyes focus on the scene naturally for more realistic viewing. Goggles can cause nausea in some wearers by confusing their depth perception. True 3-D avoids this by letting you bring different planes of the image into focus, just like in normal vision. It can also augment reality by laying virtual images over the real world-say, yellow arrows from your GPS system to guide you home. www.hitl.washington.edu
How it Works:
True 3-D adjusts the focal point of each dot of light so that it seems to come from a real object at the appropriate depth. Focus on the person running in the foreground, and the exploding car behind it looks blurry, and vice versa.
