Pointing device utilizing a photodetector array |
摘要 |
An optical detection system particularly suited to us as a pointing device uses a photodetector array capable of generating a quasi-sinusoidal signal in response to illumination with an image of appropriate size. The detection system can use either coherent or non-coherent light, and existing textures in standard materials such as paper or printed patterns. |
