The group and I is in the middle of a semester project where we are currently researching on which game systems are using camera as input or as an interactive medium? We would like some help listing some of the game systems which uses camera input, as it seems hard to find other examples. Currently we know that webcam browser games uses camera input (Newgrounds webcam games), as well as the xbox kinect. I know this questions seems rather vague, though I still hope some people is capable of helping.
The PS3 (Playstation eye) and PS2 (Eyetoy) also use camera input. I believe the PS2 was the first console to do this.
Technically the Wii also uses camera input, as the wiimote has a camera in it to handle the pointer input style, but I don't think that's the sort of thing you're talking about.
