<p>PROBLEM TO BE SOLVED: To provide a presentation system capable of resolving various failures to be caused in the conventional laser pointer, and allowing even a person who has difficulty in moving his or her fingers to use, and coping even with a multi-screen. SOLUTION: The detection signal of a position sensor 3 mounted on the arm of a presenter M is inputted via a wrist band 4 to ban image processing part 21 of a control part 2. The image processing part 21 calculates the relative position of the position of the position sensor 3 and the relative position of a preliminarily set reference position, and calculates the coordinates of the position sensor 3 on the visible image of the screen 10 based on this. The point image corresponding to the coordinates is composited with the visible image, and the composite image is projected from a liquid crystal projector 1 on the screen 10.</p> |
