Abstract

System and method for interfacing with a digital computer using a multi-function device. A preferred embodiment comprises a multi-function device comprising a controller configured to process information and regulate operations of the multi-function device, a sensor coupled to the controller, the sensor configured to capture information in a movement of the multi-function device or a movement of an object applied to the multi-function device and to provide the information to the controller, wherein the information is used to determine movement information. The multi-function device further comprises a radio frequency circuit also coupled to the controller, the radio frequency circuit is configured to exchange information with other devices via a plurality of communications networks, wherein one of the other devices is a computer and the information shared is movement information from the multi-function device.

Claims

1. A multi-function device comprising:

a controller configured to process information and regulate operations of the multi-function device;

a sensor coupled to the controller, the sensor configured to capture information in a movement of the multi-function device or a movement of an object applied to the multi-function device and to provide the information to the controller, wherein the information is used to determine movement information; and

a radio frequency circuit coupled to the controller, the radio frequency circuit configured to exchange information with other devices via a plurality of communications networks, wherein one of the other devices is a computer and the information shared is the movement information.

2. The multi-function device of claim 1, wherein the sensor comprises a positional sensor coupled to the controller, the positional sensor configured to receive transmissions from telemetry devices and to provide telemetry information to the controller.

3. The multi-function device of claim 1, wherein the sensor comprises an image sensor configured to capture optical information and to provide the optical information to the controller, wherein the optical information is used to determine movement information of the multi-function device.

4. The multi-function device of claim 3 further comprising a light source to provide light to help improve the quality of optical information captured by the image sensor.

5. The multi-function device of claim 4, wherein the image sensor periodically captures optical information, and wherein the light source is powered on only when the image sensor is capturing optical information.

6. The multi-function device of claim 3, wherein the sensor further comprises an input sensor configured to capture user input and to provide the user input to the controller.

7. The multi-function device of claim 1, wherein the sensor comprises a touch screen display configured to capture movement of the object applied to the touch screen display.

8. The multi-function device of claim 1, wherein the multi-function device is a cellular telephone with a built-in digital camera.

9. The multi-function device of claim 1, wherein a single wireless network is used to share information between the multi-function device and the computer as well as providing a voice or data connection with a remotely located user, network or database.

10. A method for operating a multi-function device as a controller device, the method comprising:

placing the multi-function device into a controller mode;

detecting changes in position of the multi-function device or in an object being applied to the multi-function device;

computing movement information from changes in position; and

transmitting movement information to a computer.

11. The method of claim 10, wherein the placing is initiated by a command or a sequence of key strokes.

12. The method of claim 10, wherein the detecting comprises:

capturing a sequence of images, wherein the capturing is performed by an image sensor; and

processing the sequence of images to detect a change in position.

13. The method of claim 10, wherein the detecting comprises:

sequentially capturing the state of sensors in a touch screen; and

processing the sequence of sensor states to detect a change in position.

14. The method of claim 10, wherein the movement information is transmitted over a short range wireless communications network.

15. The method of claim 10, wherein a voice connection can be held with a remotely located user, and a single wireless network provides both the transmission of the movement information and the voice connection.

16. The method of claim 10, wherein a data connection can be held with a remotely located user, network or database, and a single wireless network provides both the transmission of the movement information and the data connection.

17. A display system comprising:

a computer configured to display information on a display screen;

a multi-function device coupled wirelessly to the computer, the multi-function device configured to control the display of the information, the controller device comprising

a controller configured to process information and regulate operation of the controller device;

a sensor coupled to the controller, the sensor configured to capture information in a movement of the multi-function device or a movement of an object applied to the multi-function device and to provide the information to the controller, wherein the information is used to determine movement information; and

a radio frequency circuit coupled to the controller, the radio frequency circuit configured to exchange information with other devices via a plurality of communications networks, wherein one of the other devices is the computer and the information shared is movement information of the controller device.

18. The display system of claim 17, wherein the sensor comprises a positional sensor coupled to the controller, the positional sensor configured to receive transmissions from telemetry devices and to provide telemetry information to the controller.
