摘要：
The present invention provides systems and methods of using an stylus that houses optics and a detector capable of imaging display pixels. Stylus position is determined according to the number and direction of imaged pixels passing through the field of view of the stylus optics. Stylus orientation, including rotation and tilt, stylus height, stylus contact state, and stylus pressure may also be determined.
