Cam-Trax: Use Any Object as a PC Game Controller

Cam-Trax is program that claims to offer Wii-like controls to any PC game. Cam-Trax uses a webcam to interpolate the motion of your chosen control object — morocca, sprite bottle, whatever — in 3 dimensions and presumably acts as a USB HID to generate the appropriate application-level input events for that user input.

It’s a neat idea. I’m under the impression that even good webcams only get about 15fps, though, so I’m concerned about the response time. A 7ms gap between inputs just isn’t good enough in general. For simple games, though, I think Cam-Trax could be one hell of a lot of fun if it really is as good as it looks in the video.

Am I missing something on the webcam frame rate?
