If you're at all interested in the PlayStation Eye, the EyeToy for the PS3 generation, take a gander at this interview with its father, Richard Marks. Along with releasing fourâ€”yes, fourâ€”albums since 2000, Richard's added many new features to PlayStation's camera.
Among the issues seen as most important were light sensitivity, achieved by using a sensor with more area per pixel, instead of more megapixel count. The 60 fps minimum requirement, for better tracking resolution, and the four-array microphone. Definitely a cool read if you're planning on using the Eye to record your own Singstar videos and show them off online.
