<p>PROBLEM TO BE SOLVED: To provide a presentation system that establishes safety and permits to restrict unintentional movement of hands and the creation of intricate diversified point shapes. SOLUTION: A picture of two reference points A, B that are two opposite angle points of a rectangular virtual screen 11 in the vicinity of a presenter P is taken with a camera 5, and the coordinate for the static virtual screen 11 is generated based on the picture. The presenter P operates the point with a light-emitting part 61 on the virtual screen 11, and a controlling element 3 calculates the coordinate of the light-emitting part 61 on the coordinate of the virtual screen 11. Then, a point image is projected on the coordinate of the light-emitting part 61 from a liquid crystal projector 2.</p> |
