Patent ID: 8334838

Claim:
A portable electronic apparatus comprising a display unit displaying a plurality of choices; an operation detecting unit detecting a moving operation; and a selection operation control unit controlling a selection operation by moving a position of an operation target region in the plurality of choices in a certain direction based on a direction of the moving operation detected by the operation detecting unit, wherein the selection operation selects one choice from the plurality of choices, characterized in that the operation detecting unit is configured with a plurality of detection regions placed in a circular form, and when either an operation with clockwise or counterclockwise movement is detected in the plurality of detection regions, the selection operation control unit controlling the moving direction of the position of the operation target region wherein: (a) the moving direction of the position of the operation target region caused by the detection of the moving operation in a detection region and the moving direction of the position of the operation target region caused by the detection of the moving operation in another detection region is different when a speed of the moving operation is equal to or lower than a predetermined speed; and (b) the moving direction of the position of the operation target region caused by the detection of the moving operation in a detection region and the moving direction of the position of the operation target region caused by the detection of the moving operation in another detection region is the same when the speed of the moving operation is higher than the predetermined speed.
