moving the viewpoint position in the viewing direction or opposite the viewpoint direction when the portable device is moved in or opposite the first direction.

3 . The portable device of claim 2 , further comprising one or more direction buttons that when pressed causes an update to a position of a graphical user interface indicator on the display.

4 . The portable device of claim 3 , wherein each of the one or more direction buttons indicates a respective direction such that when pressed, the position of the graphical user interface indicator changes in the respective direction.

5 . The portable device of claim 2 , further comprising at least one button that when pressed causes a selection of at least one object presented in the virtual three-dimensional space on the display.

6 . The portable device of claim 5 , wherein the at least one object is selected based on the viewpoint position and a position of a graphical user interface indicator with respect to the at least one object on the display.

7 . The portable device of claim 2 , further comprising an auxiliary button that when pressed, causes storing of at least a portion of an image presented on the display based on the viewpoint position the viewing direction.

8 . The portable device of claim 2 , wherein the first direction is a direction away from a user of the portable device.

9 . The portable device of claim 2 , wherein the movement of the portable device includes tilting the portable device.

10 . The portable device of claim 2 , wherein the operations further comprise:

determining whether the sensor information indicate a movement of the portable device is rightward or leftward, and in response,

moving the viewpoint position rightward or leftward.

11 . A computer implemented method comprising:

determining a viewpoint position and a viewing direction for viewing one or more objects in a virtual three-dimensional space on a display;

receiving sensor information from a plurality of sensors of a portable device, the plurality of sensors including an acceleration sensor and a gyroscope;

determining whether the sensor information indicate a movement of the portable device in a specific first direction or opposite the first direction, and in response,

moving the viewpoint position in the viewing direction or opposite the viewpoint direction when the portable device is moved in or opposite the first direction.

12 . The method of claim 11 , further comprising:

receiving an input indicating a user selection of at least one direction button on the portable device, and in response,

causing an update to a position of a graphical user interface indicator on the display.

13 . The method of claim 12 , wherein each of the at least one direction button indicates a respective direction such that when pressed, the position of the graphical user interface indicator changes in the respective direction.

14 . The method of claim 11 , further comprising:

receiving an input indicating a user selection of at least one button on the portable device, and in response,

causing a selection of at least one object presented in the virtual three-dimensional space on the display.

15 . The method of claim 14 , wherein the at least one object is selected based on the viewpoint position and a position of a graphical user interface indicator with respect to the at least one object on the display.

16 . The method of claim 11 , further comprising:

receiving a user input indicating user selection of an auxiliary button, and in response,

causing a storage of at least a portion of an image presented on the display based on the viewpoint position the viewing direction.

17 . The method of claim 11 , wherein the first direction is a direction away from a user of the portable device.

18 . The method of claim 11 , wherein the movement of the portable device includes tilting the portable device.

19 . The method of claim 11 , further comprising:

determining whether the sensor information indicate a movement of the portable device is rightward or leftward, and in response,

moving the viewpoint position rightward or leftward.

20 . A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations comprising:

determining a viewpoint position and a viewing direction for viewing one or more objects in a virtual three-dimensional space on a display;

receiving sensor information from a plurality of sensors of a portable device, the plurality of sensors including an acceleration sensor and a gyroscope;

determining whether the sensor information indicate a movement of the portable device in a specific first direction or opposite the first direction, and in response,

moving the viewpoint position in the viewing direction or opposite the viewpoint direction when the portable device is moved in or opposite the first direction.

21 . The computer-readable medium of claim 20 , wherein the operations further comprise:

receiving an input indicating a user selection of at least one direction button on the portable device, and in response,

causing an update to a position of a graphical user interface indicator on the display.
