Abstract

An electronic mobile device includes a display for displaying a graphical element. A tilt sensor is configured to sense first and second tilt angles of the mobile device. A processor is coupled to the display and the tilt sensor and configured to move the graphical element relative to the display in a first direction based on the first tilt angle, and to move the graphical element relative to the display in a second direction based on the second tilt angle.

Claims

1. An electronic device comprising:

a display for displaying a graphical element;

a sensor for determining a tilt angle of the display;

a processor coupled to the display and the sensor and configured to;

move the graphical element relative to the display in a first direction based on a first tilt angle; and

move the graphical element relative to the display in a second direction based on a second tilt angle.

2. The electronic device of claim 1 wherein the first tilt angle relates to forward-backward tilting of the display and the second tilt angle relates to side-to-side tilting of the display.

3. The electronic device of claim 2 wherein the processor alters the position of the graphical element in response to at least one of the first and second tilt angles exceeding a threshold.

4. The electronic device of claim 1 wherein the graphical element'"'"'s position in the first direction is altered at a rate based on the first tilt angle.

5. The electronic device of claim 1 wherein the graphical element'"'"'s position in the first direction is altered at a rate based on an amount of time that the first tilt angle has exceeded a threshold.

6. The electronic device of claim 1 wherein the graphical element'"'"'s position in the first direction is altered at a rate based on a number of different thresholds the first tilt angle has exceeded.

7. The electronic device of claim 1 wherein the processor stores a current first tilt angle as a first reference tilt angle and a current second tilt angle as a second reference tilt angle, relative to which subsequently received first and second tilt angles are compared by the processor.

8. The electronic device of claim 1 wherein the graphical element is a list of items.

9. The electronic device of claim 1 wherein the graphical element is a selection box that designates an item among a list of items displayed by the display.

10. The electronic device of claim 9 wherein the list of items is in the form of a spreadsheet, and the first direction is along columns of the spreadsheet, and the second direction is along rows of the spreadsheet.

11. An electronic device comprising:

a display for displaying a graphical element;

a sensor for determining a tilt angle of the display;

a processor coupled to the display and the sensor and configured to receive a tilt angle signal from the sensor, indicative of a tilt angle, and move the graphical element relative to the display in response to the tilt angle exceeding a threshold.

12. The electronic device of claim 11 wherein, after the tilt angle exceeds the threshold, the graphical element'"'"'s position is altered at a rate based on the tilt angle.

13. The electronic device of claim 11 wherein, after the tilt angles exceeds the threshold, the graphical element'"'"'s position is altered at a rate based on an amount of time that the tilt angle has exceeded the threshold.

14. The electronic device of claim 11 wherein, after the tilt angles exceeds the threshold, the graphical element'"'"'s position is altered at a rate based on a number of different additional thresholds the tilt angle has exceeded.

15. The electronic device of claim 11 wherein the graphical element is a list of items.

16. The electronic device of claim 11 wherein the graphical element is a selection box that designates an item among a list of items displayed by the display.

17. The electronic device of claim 11 wherein the processor stores a current tilt angle as a reference tilt angle, relative to which subsequently received tilt angles are compared by the processor.

18. An electronic device comprising:

a display for displaying a graphical element;

a sensor for determining a tilt angle of the display;

a processor coupled to the display and the sensor and configured to receive a tilt angle signal from the sensor, indicative of a tilt angle, and move the graphical element relative to the display at a rate that is based on a number of thresholds the tilt angle has exceeded.

19. The electronic device of claim 18 wherein the graphical element is a list of items.

20. The electronic device of claim 18 wherein the graphical element is a selection box that designates an item among a list of items displayed by the display.
