Abstract
A pointing element used to operate a screen includes a front end light emitter and a controller that causes the front end light emitter to emit light for signal light transmission, and the controller causes the front end light emitter to emit light in a first light emission mode in a state in which the pointing element is not in contact with the screen and causes the front end light emitter to emit light in a second light emission mode in which the amount of light emitted from the front end light emitter is smaller than in the first light emission mode in a state in which the pointing element is in contact with the screen.
