Abstract:
1. An information processor for processing information signals, the apparatus comprising: an operating mechanism configured to select one of a plurality of operations when rotated and then pushed; and a controlling mechanism configured to monitor the operated status of the operating mechanism and to open an operation window, displaying each of the plurality of operations, according to the operated status of the operating mechanism, wherein the controlling mechanism is configured to detect a first pushed status of the operating mechanism, in which the operating mechanism has been pushed less than a predetermined length of time, and a second pushed status of the operating mechanism, in which the operating mechanism has been pushed for longer than the predetermined length of time, the controlling mechanism is configured to undo an operation previously selected by the first pushed status when the second pushed status is detected, and said operating mechanism is not rotated between when the first pushed status and the second pushed states are detected, the controlling mechanism is configured to detect the rotation and changes a menu item, and upon detecting the first push status, the controlling mechanism is configured to cause a display of an operation guidance window configured to guide use of an active application program, and to cause a display of an operation launching window configured to launch an application program when there is no active application program.
