ABSTRACT:
A method for displaying a display object on a display screen, which method permits efficient simultaneous input operation by allowing a display object to be shown on a display screen without producing an area wherein an electronic pen is disabled when simultaneous input is performed with the electronic pen held in a dominant hand and an electronic cursor held in the other hand. The electronic pen is operated by the operator's dominant hand and the electronic cursor by the other hand on an input table of a coordinate input device. A pointer indicating the position specified by the electronic pen, a pointer indicating the position specified by the electronic cursor, and display objects associated with the electronic cursor are displayed on the display screen. The display objects on the display screen are shown at the location of the other hand, i.e., the non-dominant hand, so that the electronic cursor does not interfere with the movement of the electronic pen when the operator moves the electronic pen to work on the display objects on the input table.
