Research Abstract	As a new educational system that replaces of the e-learning system of the web base used widely at present, we proposed and developed a desk information projection and shared system "VisionDesk". We made a prototype that was implemented with the pen-tablet type liquid crystal monitor at first. However, we obtained the result that the operation with the tip of a finger is suitable for natural and intuitive operation Therefore, we developed the multipoint recognition method by the detection of the tip of a finger of coloring with a web camera at the next stage. Additionally, we implemented the gesture interface. The optimum value of the recognition parameter in a click and various operations of drag were obtained by experiment with a prototype model. In the final phase, it was confirmed that recognition with the web camera was changed from the front direction to the ceiling direction, and the multipoint recognition operated with the tip of a finger of coloring as well as the direction of the front.
