Abstract: An information processing apparatus includes a touch panel configured to provide a display and detect an operation on the display; and a display control part configured to cause a second operation pad to be displayed, in place of a first operation pad, in the touch panel when the touch panel that selectively displays the first operation pad having a first switching button or the second operation pad having a second switching button detects an operation on the first switching button, and cause the first operation pad to be displayed in place of the second operation pad when the touch panel detects an operation on the second switching button.

Abstract: A cellular phone includes: a user interface for accepting an input; a communication interface for making a call via a radio communication with a base station; a display unit for displaying figures and characters; a first display controller for setting a display orientation of the display unit in one of a first display orientation and a second display orientation; and a second display controller for controlling the display unit so that the display orientation is set in the first display orientation if the communication interface starts a call. The first display orientation means a orientation that connects a top sideline of the display unit and a bottom sideline of the display unit, and the second display orientation means a orientation that is obtained by rotating the first display orientation by about 90° clockwise or counterclockwise about a vertical axis of the display unit.
