PROBLEM TO BE SOLVED: To solve the inconvenience due to the fact that a plurality of cursors are displayed on a projection image.SOLUTION: A control unit of a pointer determines whether or not flicker has been detected on the basis of an image photographed by an imaging unit (step S3). When flicker has been detected, the control unit turns off a pointer function unit and turns on a mouse function unit (step S5). Thus, a first cursor displayed on a display unit of a personal computer is projected by a projector and displayed on a screen; however, a second cursor is not displayed on the screen even when the apical surface of the pointer is directed toward the screen 100 because the pointer function unit has been turned off. With this configuration, it is possible to avoid the state where the first cursor and second cursor are concurrently displayed on the screen 100. |
