Abstract

A hand-held wireless communications device includes a camera integrated within a housing of the wireless communications device, a front-facing lens assembly to focus light onto the camera, a display, and a controller connected to the camera and the display. The controller controls the camera to capture an image of another device that is in front of its display. The device can then analyze the image to extract information specific to the other device, and utilize that information to identify and authenticate the other device. Once identified and authenticates, the devices are able to share data and information with each other.

Claims

1. A method of pairing a first camera-equipped wireless communications device with a second camera-equipped wireless communications device, each device facing the other and having a front-facing camera lens, the method comprising:

capturing, at the first wireless communications device, an image of a graphical indicator displayed on a display of the second wireless communications device;

analyzing the graphical indicator in the captured image; and

pairing the first and second wireless communications devices for communications based on the analysis.

2. The method of claim 1 wherein capturing the image of the graphical indicator displayed at the second wireless communications device comprises:

controlling a camera at the first wireless communications device to capture an image of a display screen of the second wireless communications device at predetermined time intervals; and

increasing the time interval length if the captured image does not contain the graphical indicator.

3. The method of claim 1 further comprising determining whether the graphical indicator is included in the captured image.

4. The method of claim 3 wherein if the graphical indicator is in the captured image, the method further comprises:

comparing information associated with the graphical indicator in the captured image to corresponding information stored in a memory; and

identifying and authenticating the second wireless communications device based on the results of the comparison.

5. The method of claim 4 wherein the graphical indicator in the captured image comprises a graphical icon associated with the second wireless communication device.

6. The method of claim 4 wherein the information associated with the graphical indicator comprises data encoded into the graphical indicator.

7. The method of claim 1 further comprising determining a predefined type of interaction to occur between the first and second wireless communications devices based on the analysis.

8. The method of claim 7 wherein the predefined type of interaction comprises sharing data between the first and second wireless communications devices.

9. The method of claim 7 wherein the predefined type of interaction comprises transferring one or more components of a game application from one of the first and second wireless communication devices to the other of the first and second communication devices.

10. The method of claim 7 wherein the predefined type of interaction comprises communicating commands from one of the first and second wireless communication devices to control one or more functions at the other of the first and second communication devices.

11. The method of claim 1 further comprising generating, at the first wireless communications device, a local graphical indicator to appear on a display of the first wireless communications device.

12. The method of claim 11 further comprising generating the local graphical indicator based on data that can be used to identify and authenticate the first wireless communication device to the second wireless communication device.

13. The method of claim 11 wherein pairing the first and second wireless communications devices based on the analysis comprises pairing the first and second wireless communications devices based on the content of an application executing on one or both of the first and second wireless communications devices.

14. A hand-held wireless communications device comprising:

a camera integrated within a housing of the wireless communications device;

a front-facing lens assembly to focus light onto the camera;

a display; and

a controller connected to the camera and the display and configured to;

control the camera to capture an image of a graphical indicator displayed on a display of a remote wireless communications device;

analyze the captured image of the graphical indicator displayed by the remote device; and

pair the wireless communications device and the remote device for communications based on the analysis.

15. The device of claim 14 wherein the controller is further configured to:

control the camera to capture the image of the graphical indicator displayed on the display of the remote device at predetermined time intervals; and

increase the time interval length if the captured image does not contain the graphical indicator.

16. The device of claim 14 wherein the controller is further configured to determine whether the graphical indicator displayed on the display of the remote device is included in the captured image.

17. The device of claim 16 wherein if the graphical indicator is included in the captured image, the controller is further configured to:

compare information associated with the graphical indicator in the captured image to corresponding information stored in a memory; and

identify and authenticate the remote device based on the results of the comparison.

18. The device of claim 17 wherein the graphical indicator in the captured image comprises an avatar associated with a game application being executed by the remote device.

19. The device of claim 17 wherein the information associated with the graphical indicator comprises encoded data.

20. The device of claim 14 wherein the controller is further configured to determine a predefined type of interaction to occur between the wireless communications device and the remote device based on the analysis.

21. The device of claim 20 wherein the predefined type of interaction comprises sharing data between the devices.

22. The device of claim 20 wherein the predefined type of interaction comprises transferring one or more components of a game application from one of the devices to the other of the devices.

23. The device of claim 20 wherein the predefined type of interaction comprises communicating commands from one of the devices to control one or more functions at the other of the devices.

24. The device of claim 14 wherein the controller is further configured to generate a local graphical indicator to appear on a display of the wireless communications device.

25. The device of claim 23 wherein the controller is further configured to generate the local graphical indicator based on data that can be used to identify and authenticate the wireless communication device to the remote device.

26. The device of claim 14 wherein the controller is further configured to pair the devices based on the content of an application executing on one or both of the devices.
