Patent ID: 8599151

Claim:
An information processing apparatus, comprising: a first display unit for displaying book data per page; a second display unit provided so as to be adjacent to the first display unit for displaying the book data per page; an axial part provided between the first and second display units; a first detecting unit for calculating rotational angular displacement of the first display unit around the axial part by detecting the angular speed of the first display unit around the axial part and integrating the first display unit's angular speed with respect to an elapsed time period; a second detecting unit for, calculating rotational angular displacement of the second display unit around the axial part by detecting the angular speed of the second display unit around the axial part and integrating the second display unit's angular speed with respect to an elapsed time period; and a display page controller configured to change the pages displayed on the first display unit and the second display unit to page up or page down based on the rotational angular displacement of the first display unit and the rotational angular displacement of the second display unit.
