Sony’s SimulView Could End Split-Screen Gaming for Good
“Remember having to cover part of the television when playing a split-screen video game so your friends wouldn’t cheat by looking at your screen? Well no more we say! Sony has tapped the miracle of 3D technology to let you play your favorite split-screen games in the privacy of a pair of 3D glasses.
The Sony 3D display is a small, relatively inexpensive 3D-capable television paired with active 3D glasses. These glasses, however, also make it possible for two people to look at the screen and receive two entirely different images. A player can load up a game and enjoy a full-screen view while a friend can play the same game but see their own full, unique screen. Sony calls this “SimulView.”
3D technology in general works by sending two images of the same scene at different perspectives to each of your eyes. Your brain automatically converts the difference between the two images, thereby creating the illusion of depth. 3D glasses use fast shutters, which alternately show and black-out the image from one eye to another.
SimulView takes advantage of this property. Instead of sending two similar but different images to the same person, SimulView shows just one of the images to each set of glasses. Because of this, SimulView delivers a full-screen 2D image to each player, but from their in-game point of view. In other words, no more split screen, no more loss of screen real estate as your avatars’ views share the same 24-inch display, no more worrying that Player B can see your secret plan to capture the flag.”
