A method for using a rotating input device assigns multiple functions to the rotating input device without requiring special switching operations. When a rotating input operation of the rotating input device is first performed, the device detects a rotary position of the rotating input device at which the initial operation was performed. A plurality of regions are set up along 360 degrees of input orientation for the rotating input device, and a different operation is assigned to each region. When the first rotating input operation is performed, the region of the position at which the initial operation is performed is identified, and subsequent rotating input operations are used to control the operation assigned to the selected region.
