ABSTRACT:
The drawing apparatus images the operation article by intermittently emitting light to the operation article to derive a location of the operation article on the screen. The cursor is displayed at the location of the operation article on the screen. Therefore, the cursor follows movement of the operation article. Then, the star images are displayed on the motion path of the cursor. In this way, a motion path of the operation article can be displayed by operating the operation article in the air.
