Third Eye Interfaces offers enhancements for EyeToy

"If you're a fan of the EyeToy camera for the Playstation 2 but would like to see it more accurately interpret your movements in three dimensions, Third Eye Technologies may have the answer. Their system projects multiple images at the camera, allowing it to better interpret angles and depth, making it more suitable for games that depend on fine control, such as flight simulators and first-person shooters. Of course, the technology requires a dedicated controller, undoing the EyeToy's best feature - the ability to use your whole body to interact with the game - but if you want to do more with your EyeToy than dance and jump around, this could be the way to go."
