thirdEye is a new technique that enables multiple viewers to see different things on a same display screen at the same time. With thirdEye, - We can have a public sign board where a Japanese tourist sees all the instructions in Japanese and an American in English. - We don't need to have the split screen in games now. Each player can see his/her personal view of the game on the TV screen. - Two people watching TV can watch their favorite channel on a single TV screen. - A public display can show secret messages or patterns. - In the same movie theater, people can see different end of a suspense movie.
