Re: "mouse encoders"

A couple of years ago some people looked into this. There are gaming mice that are fast enough. The problem is optics, illumination and the fact that optical mice are designed to work best on a laminate surface. Avago holds most of the patents on the algorithms used to detect the movement and are suing a bunch of other chip companies. Using a 1/2 VGA camera could work if you got the focus and lighting right. Then you would have to develop the algorithm and have enough processing speed. The good algorithms are closely guarded IP.
