Abstract

An information processing apparatus is provided which includes 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 detecting rotational angular displacement of the first display unit around the axial part, a second detecting unit for detecting rotational angular displacement of the second display unit around the axial part, and a display page controller for displaying a page N displayed on the first display unit on the second display unit, or displaying the page N displayed on the second display unit on the first display unit, based on the rotational angular displacement of the first display unit and the rotational angular displacement of the second display unit.

Claims

1. 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.

2. The information processing apparatus according to claim 1:

wherein

the display page controller judges that the first and second display units shift to a close state when displacement difference between the rotational angular displacement of the first display unit and the rotational angular displacement of the second display unit becomes larger than a predetermined first threshold from an open state of the first and second display units.

3. The information processing apparatus according to claim 2:

wherein

the display page controller judges that the first and second display units shift to the open state again when the displacement difference between the rotational angular displacement of the first display unit and the rotational angular displacement of the second display unit becomes smaller than a predetermined second threshold after the first and second display units shift to the close state.

4. The information processing apparatus according to claim 3:

wherein

the display page controller displays a page N displayed on the first display unit onto the second display unit, or displays the page N displayed on the second display unit onto the first display unit, based on the rotational angular displacement of the first display unit and the rotational angular displacement of the second display unit.

5. The information processing apparatus according to claim 4:

wherein

the display page controller calculates total displacement of the rotational angular displacement of the first display unit and total displacement of the rotational angular displacement of the second display unit after the first and second display units start to shift from the open state to the close state, and displays the page N displayed on the first display unit onto the second display unit when judging that the total displacement of the rotational angular displacement of the first display unit is larger than a predetermined third threshold and larger than the total displacement of the rotational angular displacement of the second display unit.

6. The information processing apparatus according to claim 5:

wherein

the display page controller calculates total displacement of the rotational angular displacement of the first display unit and total displacement of the rotational angular displacement of the second display unit after the first and second display units start to shift from the open state to the close state, and displays the page N displayed on the second display unit onto the first display unit when judging that the total displacement of the rotational angular displacement of the second display unit is larger than a predetermined third threshold and larger than the total displacement of the rotational angular displacement of the first display unit.

7. The information processing method comprising the steps of:

displaying book data on a first display unit per page;

displaying the book data on a second display unit provided so as to be adjacent to the first display unit per page;

calculating rotational angular displacement of the first display unit around an axial part provided between the first and second display units 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;

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

changing 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.
