ABSTRACT:
An optical projection and capture system includes an image sensor integrated with an optical projection device. Additionally, the integrated device may be coupled with a laser pointer to deliver interactive presentations. The laser pointer may be pulsed to improve identifying and tracking a laser light spot on a projected image. These applications may be extended to rear projection systems for gaming and interactive graphics.
