摘要：This paper presents a system that enables a presenter to work directly on the projection without the typical interruption of the presentation flow being caused by a mouse or keyboard activity. The lecturer simply uses his fingers as a natural and intuitive pointing device. The system consists of an LED, a standard webcam, a video projector, and a small software system running on a notebook computer. The camera is positioned such that it views the projection area. After a few calibration clicks, the mouse emulation is functional at any place of the projection area.
