ABSTRACT:
To provide input means by which a mouse position can be accurately pointed to in a touch panel input system that does not have a pointing device capable of accurate pointing such as a mouse. Input events, which are mouse events (touches of a touch panel display) or keyboard events, are registered to be hooked, and a mouse pointer window is generated. An event hook section is notified of an occurrence of an input event, and the event is processed. In processing the event, a click event of the mouse event is disabled, and the mouse pointer window is displayed at the mouse position. When a mouse movement is selected on a tool window or a keyboard, the mouse position and the mouse pointer window are moved to that direction. When a click event is selected on the tool window or the keyboard, the click event is generated and issued.
