INFORMATION PROCESSING APPARATUS AND DISPLAY CONTROL METHOD
First Claim
1. An information processing apparatus comprising:
- a display unit on which an object is displayed;
a position detection unit for detecting a position of an operating tool that is made to contact a surface of the display unit or that is brought into proximity thereof;
a reference position determination unit for determining as a reference position a position of an operating tool that is detected first by the position detection unit when a plurality of operating tools are made to contact the display unit or were brought into proximity thereof;
a display change operation specifying unit for specifying, according to a moving direction of a position of an operating tool that is detected N-th (N≧
2) by the position detection unit, a specific display change operation associated with the direction; and
a display control unit for performing on the object the display change operation specified by the display change operation specifying unit with the reference position determined by the reference position determination unit as a reference.

Abstract
An information processing apparatus is provided which includes a display unit on which an object is displayed, a position detector for detecting a position of an operating tool that is made to contact a surface of the display unit, a reference position determination unit for determining as a reference position a position of an operating tool that is detected first by the position detector when a plurality of operating tools are made to contact the display unit, a display change operation specifying unit for specifying, according to a moving direction of a position of an operating tool that is detected N-th (N≧2) by the position detector, a specific display change operation associated with the direction, and a display controller for performing on the object the display change operation specified by the display change operation specifying unit with the reference position determined by the reference position determination unit as a reference.

7. A display control method comprising the steps of:
-
detecting a position of an operating tool that is made to contact a surface of a display unit on which an object is displayed or that is brought into proximity thereof; determining as a reference position a position of an operating tool that is detected first in the step of detecting when a plurality of operating tools are made to contact the display unit or were brought into proximity thereof; specifying, according to a moving direction of a position of an operating tool that is detected N-th (N≧
2) in the step of detecting, a specific display change operation associated with the direction; andperforming on the object the display change operation specified in the step of specifying with the reference position determined in the step of determining as a reference.
