http://www.tveyes3d.com/demo Instead of using stereopsis, TV Eyes 3D uses "depth of field" a depth focusing effect caused by the aperture of a camera. By altering the different levels of focus in a regular TV picture, TV Eyes Glasses make focal cues look like depth cues. The result is a deeper, clearer, sharper, more solid and three dimensional picture. Distances look farther, spaces look larger, people and objects stand out more from the background and look more contoured and three dimensional. Computer generated effects and green screen effects are integrated more seamlessly into the movie.
