wherein a leftward tilt movement of the portable operation device causes a leftward movement of the viewpoint position in the virtual three-dimensional space, and

wherein a rightward tilt of the portable operation device causes a rightward movement of the viewpoint position in the virtual three-dimensional space, and

wherein the portable operation device is switched between a standby mode and a normal operation mode.

2. The portable operation device according to claim 1 , wherein the portable operation device is switched between the standby mode and the normal operation mode by a power button of the portable operation device.

3. The portable operation device according to claim 1 , wherein the portable operation device is switched between the standby mode and the normal operation mode by at least the outputs of the acceleration sensor and the gyroscope.

4. The portable operation device according to claim 1 , wherein a posture of each of the plurality of objects is changed based on movement of the viewpoint position or movement of the viewpoint direction.

5. The portable operation device according to claim 1 , further comprising:

a biosensor to detect at least one of blood pressure, pulsation frequency, fingerprint, or heart rate of the user.

6. The portable operation device according to claim 1 , wherein locations of the plurality of objects are determined based upon an attribute of each object, content of each object, or auxiliary information associated with each object.

7. The portable operation device according to claim 1 , wherein an upward movement of the portable operation device causes an upward movement of the viewpoint position and a downward movement of the portable operation device causes a downward movement of the viewpoint position.

8. The portable operation device according to claim 1 , wherein the viewpoint direction is rotated based upon movement detected by the gyroscope.

9. The portable operation device according to claim 1 ,

wherein the display is connected to a computer via a wired connection, and

wherein the portable operation device is connected to the computer via a wireless connection.

10. The portable operation device according to claim 1 , further comprising:

a user detection circuit for detecting a presence of the user;

wherein the user detection circuit switches the portable operation device to an active operation mode when the user is detected.

11. The portable operation device according to claim 1 ,

wherein portable operation device is coupled to a computer, and

wherein the display is connected to the computer.

12. The portable operation device according to claim 1 , wherein the display is connected directly to the portable operation device.

13. The portable operation device according to claim 1 , further comprising:

a game program downloaded from a server computer,

wherein the game program is controlled using the plurality of sensors.

14. The portable operation device according to claim 1 , wherein an upward movement of the portable operation device causes an upward movement of the viewpoint and a downward movement of the portable operation device causes a downward movement of the viewpoint.

15. A method for controlling a viewpoint position and a viewpoint direction on a display using a portable operation device, the method comprising:

displaying, on the display, a plurality of objects disposed in a virtual three-dimensional space viewed from the viewpoint;

receiving sensor information from a plurality of sensors including an acceleration sensor and a gyroscope;

detecting movement of the portable operation device by a user using the sensor information;

moving the viewpoint position and the viewpoint direction in the virtual-three dimensional space according to the detected movement; and

selecting an object from the plurality of objects by operating a cursor to select the object,

wherein a leftward tilt movement of the portable operation device causes a leftward movement of the viewpoint position, and

wherein a rightward tilt of the portable operation device causes a rightward movement of the viewpoint position

wherein the portable operation device is switched between a standby mode and a normal operation mode.

16. A non-transitory, computer readable storage medium having stored thereon a computer program, which when executed by a computer system causes the computer system to carry out actions, comprising:

displaying, on the display, a plurality of objects disposed in a virtual three-dimensional space viewed from the viewpoint;

receiving sensor information from a plurality of sensors including an acceleration sensor and a gyroscope;

detecting movement of the portable operation device by a user using the sensor information;

moving the viewpoint position and the viewpoint direction in the virtual-three dimensional space according to the detected movement; and

selecting an object from the plurality of objects by operating a cursor to select the object,

wherein a leftward tilt movement of the portable operation device causes a leftward movement of the viewpoint position,
