Well, kinda sorta. It started with the EyeToy - and how many knew about that? - a camera manufactured by Logitech for Sony, for the PS2 and PSP. It required a well-lit room (how many of us gamers prefer gaming in a dimly lit room?) and the number of games released each year that had the EyeToy enhancement could be counted on the fingers of one hand.

Now, an Israeli company has come out with the ZCam which uses a different method of tracking. It uses reflection of infra-red impulses from the camera - meaning, there's no light requirement.

The EyeToy worked in 2D only. The Wii works in 3D, as will the ZCam. How it will impact games and the way we game is still up in the air. Check out the article on CNET linked above. It's interesting reading. What do you think?
