Abstract

A method (500) and apparatus (601) generate an input signal based on the orientation of a device. A sensor (302) such as a camera, a gyro, or an accelerometer detects a change in device orientation and generates a position input signal that is provided to an application program (612) such as a game program, a text messaging program, or a user interface program to affect an operation thereof. The input signal can, for example, affects a navigation position associated with the application program.

Claims

1. A method for providing an input to an application program executing on a device, the method comprising:

detecting a change in an orientation of the device;

generating an input signal associated with the change in the orientation; and

providing the input signal to the application program to change an operation performed by the application program.

2. A method in accordance with claim 1, wherein the sensor includes one or more of a camera, a gyro, and an accelerometer.

3. A method in accordance with claim 1, wherein the application program includes one or more of a game program, a text processing program, and a user interface program.

4. A method in accordance with claim 1,

wherein the input signal includes position information, and

wherein the providing includes providing the position information to change a cursor position associated with the application program.

5. A method in accordance with claim 1, wherein:

the input signal includes position information,

the application program includes a simulated keyboard program,

the providing includes providing position information to change a cursor position associated with the simulated keyboard program,

the cursor position is associated with a key on the simulated keyboard program, and

the method further comprises selecting the key when the cursor position coincides with the key.

6. A method in accordance with claim 1, wherein:

the input signal includes position information,

the application program includes a game program, and

the providing includes providing position information to change an action position associated with the game program, the action position associated with a user guided action of the game program.

7. A method in accordance with claim 1, wherein the device includes a wireless communication unit.

8. A method for controlling a cursor position associated with an application program executing on a device, the method comprising:

detecting a change in an orientation of the device relative to a reference position of the device;

using a sensor to generate a position signal associated with the change in the orientation;

processing the position signal based on a sensor type associated with the sensor to generate a cursor position signal; and

updating the cursor position based on the cursor position signal.

9. A method in accordance with claim 8, wherein the sensor includes one or more of a camera, a gyro, and an accelerometer.

10. A method in accordance with claim 8, wherein the application program includes one or more of a game program, a text processing program, and a user interface program.

11. A method in accordance with claim 9, wherein the device includes a wireless communication unit.

12. An apparatus for navigating within an application program in a device, the apparatus comprising:

a memory for storing the application program;

a sensor having an associated sensor type, the sensor adapted to;

determine an orientation of the device, and

generate a position signal proportional to a change in the orientation of the device; and

a processor coupled to the memory and the sensor, the processor adapted to;

execute the application program,

process the position signal according to the sensor type to generate a navigation position, and

update a navigation action associated with the application program using the navigation position.

13. An apparatus in accordance with claim 12, wherein the sensor type includes one or more of a camera, a gyro, and an accelerometer.

14. An apparatus in accordance with claim 12, wherein the application program includes one or more of a game program, a text processing program, and a user interface program.

15. An apparatus in accordance with claim 12, wherein the device includes a wireless communication unit.

16. An apparatus according to claim 12, further comprising;

a selector coupled to the processor, the selector configured to generate a select signal,

wherein the application program includes a simulated keyboard program, and

wherein the processor in updating the navigation action is further configured to update the navigation action associated with the simulated keyboard program, the navigation position capable of being associated with a key on the simulated keyboard program, and wherein a key associated with the navigation position is selected when the navigation position coincides with the key and the select signal is generated.

17. An apparatus according to claim 16, wherein the selector includes a select button on the device.

18. An apparatus according to claim 12,

wherein the application program includes a game program, and

wherein the processor in updating the navigation action is further configured to update the navigation action associated with the game program, the navigation position corresponding to a user guided action position associated with the game program.

19. An apparatus according to claim 12, further comprising a selector coupled to the processor, the selector configured to generate a select signal,

wherein the application program includes a user interface program, and

wherein the processor in updating the navigation action is further configured to update the navigation action associated with the user interface program, the navigation position corresponding to a selection position associated with an action of the user interface program, and

wherein the action associated with the selection position is selected when the position coincides with the selection position and the select signal is generated.

20. An apparatus according to claim 19, wherein the action includes a menu selection associated with the user interface program.
