<p>PROBLEM TO BE SOLVED: To provide a presentation system that can establish safety while using laser light of good visibility, and also can restrict the unintentional movement of hands and correspond to a multi-screen or the like. SOLUTION: When infrared light is projected from a pointer 3 onto a screen 10, an operation part seeks the position of the infrared light on the screen 10 from the image taken with an imaging means. The operation part computes the emerging angle of the laser light from the sought position of the infrared light, and a laser projection means 5 emits the laser light at the computed emerging angle. Therefore, the point of the laser light is projected onto the position of the infrared light projected with an indicating means.</p> |
