A presentation using a projector and a laser pointer is a very popular scene at a business meeting or at an academic conference. A system operate the mouse cursor by a laser pointer is proposed to perform more comfortable presentation. However, as for the proposed system using the image processing approach, the using environment is limited because of the frame rate, environment light problems. To wipe such a disadvantage, an additional operation tools equipped with an acceleration sensor that coordinate the movement of the cursor based on visual feedback are suggested. But this could make the usability spoiled if the presenter is not well trained. In this system, a modulated laser source is adopted to reduce the surrounding light noise, and the PSD sensor gives a very rapid response than a CCD camera system. In addition, we become able to operate it in real time because no image processing was used.
