Abstract
with the great advantages of interactive projection technology, the new optical-electronic human-computer interactive large screen display system has been paid more and more attention. In this paper, the approach with a new optical structure based on linear detectors has been presented. This system consists of computer, projector, camera and digital pen, and the camera uses two linear detectors to detect the infrared light point, which is reflected by two stripe mirrors separately, so that the location of the light point could be measured. This method has the advantages of anti-obstruct, fast tracking, low-cost, and can be widely used in teaching, training, and so on.
