OBJECT OPERATION SYSTEM, OBJECT OPERATION CONTROL PROGRAM AND OBJECT OPERATION CONTROL METHOD

摘要

An object operation system which can appropriately recognize multi-touch gestures, an object operation control program and an object operation control method are provided. An object operation system includes a display section, an operation section and a controller. In response to recognizing a multi-touch gesture to touch a screen of the display section at three or more touch points simultaneously on the basis of information output from the operation section, the controller determines an operation target of the multi-touch gesture in accordance with whether or not a predetermined number of touch points among the three or more of touch points are located on one object or the area of an object group displayed on the screen. In response to a change in position of at least one of the predetermined number of touch points, the controller operates the operation target in accordance with the change.
