Abstract

A highly convenient display system is provided. A display system that enables a screen to be operated easily with a laser pointer is provided. A display system that enables a screen to be operated by a large number of people is provided. The display system includes a light-emitting apparatus and a display device. The light-emitting apparatus includes a means for emitting visible laser light and a means for emitting invisible light. The display device includes a display unit including a means for displaying an image and a means for obtaining positional information on a portion irradiated with the visible light, and a means for receiving the invisible light. The display system has a function of performing processing in accordance with the positional information when the invisible light is received.

Claims (41)
