The published patent called “3D Shutter Glasses with Mode Switching based on Orientation to the Display device” and was numbered 20100177174.
The idea is to have a shuttered filter in the 3D glasses that are used to block out the background images and instead project the video image to the glasses of only that person while projecting a different image to the person beside them and so on.
The advantages to this technology are too good to ignore! A couple could watch different TV shows while on the same bed! Gamers will surely welcome this technology. Multiplayer gaming will take a whole new meaning if this technology is implemented.
The patent indicates that the 3D glasses might have built-in speakers for the sounds of its respective screens. There are a few problems however. If two people are watching different shows, privacy could be an issue where one show might be about the Holocaust while the other show is a new episode from Family guy!
However the technology seems promising and its only a matter of time before Sony can get some demo products out. Also I am not sure how this product might work, Instead of buying many TVs I might settle for just one Screen shared TV, thats a loss of sale for Sony!
