Abstract

In an information processing device, when an operation button is pushed, a menu is displayed on the screen of an LCD. When the whole portable type information processing device (PDA) is rotated around the X-axis, the Y-axis or the Z-axis with the operation button being pushed, the rotation is detected by a triaxial gyro sensor, and on the basis of the detection result a cursor displayed on the screen is moved on the menu. By releasing the operation button when the cursor is located on a desired menu item, the selection of the menu item at which the cursor is located is settled, and the processing corresponding to the selected menu item is started.

Claims

1. A portable graphical view production system comprising:

a housing including an image display;

a location input device mounted in the housing for inputting a current location of the system;

a viewpoint position/line-of-sight direction determination means mounted in the housing for determining a viewpoint position and line-of-sight direction, said viewpoint position/line-of-sight direction determination means including an angular velocity sensor which detects changes in the angular velocity of the system;

a map data storage device mounted in the housing for providing map data corresponding to said current location of the system; and

a graphic data coordinate conversion means mounted in the housing for converting said map data on the basis of said current location, said viewpoint position line-of-sight direction and changes in the angular velocity wherein the converted map data is displayed by the image display.

2. The portable graphical view production system of claim 1 wherein the location in put device is a global positioning system.

3. The portable graphical view production system of claim 1 wherein the map data storage device comprises a removable HDD card.

4. The portable graphical view production system of claim 1 further comprising a viewpoint converting input portion for changing the viewpoint and line of sight determined by said viewpoint/line-of-sight direction determination means.

5. The portable graphical view production system of claim 4 wherein said viewpoint converting input portion includes a manually actuated switch adapted to provide a signal to the graphic data coordinate conversion means when the switch is actuated.

6. The portable graphical view production system of claim 1 wherein said angular velocity sensor is a gyroscopic sensor.

7. The portable graphical view production system of claim 4 wherein the viewpoint position/line of sight direction determination means and the graphic coordinate conversion means comprise a microprocessor adapted to determine a viewpoint position based on the current location and an output from the viewpoint converting input portion.

8. The portable graphical view production system of claim 7 wherein the system is housed in a hand held device configured to be operated by a single hand.

9. The portable graphical view production system of claim 1 wherein the converted map data displayed by the image display is displayed as a perspective view of a map based on the viewpoint selected and the line of site.

10. The portable graphical view production system of claim 9 further comprising a viewpoint changing means for changing the selected viewpoint.

11. The portable graphical view production system of claim 10 wherein viewpoint height is changed in response to said viewpoint changing means.

12. The portable graphical view production system of claim 1 wherein said converted map data is projected onto the image display such that the image display is perpendicular to the line of sight.

13. The portable graphical view production system of claim 1 wherein said image display further displays an index for identifying a destination location.
