Abstract

The present invention comprises methods and apparatus that enable a user of a portable computing device to selectively communicate with other users of portable computing devices while those devices are engaged in an ad-hoc network. More specifically, the present invention enables a first user of a first portable computing device to gain information about and/or send a message to a second user of a second portable computing device by pointing a portion of the first portable computing device at the then current physical location of the second user. In this way a first user of a first portable computing device may naturally and conveniently select a second user of a second portable computing device from among a plurality of users of other portable computing devices engaged in an ad-hoc network and selectively gain information about the second user and/or send a message to the second user.

a plurality of second portable computing devices, each of the second portable computing devices including a second location sensor and a second wireless communication link, the second wireless communication link enabling the establishment of at least one ad-hoc networks with other enabled portable computing device within a local proximity of the second portable computing device;

targeting routines running on the first portable computing device for performing a targeting determination as to whether the user aiming portion of the first portable computing device is aimed substantially at a particular second portable computing device, the targeting determination being performed at least in part based on a substantially current location value of the first portable computing device, a substantially current aiming orientation value of the first portable computing device, and substantially current locative data indicating a location of the particular second portable computing device, the locative data being received by the first portable computing device from the particular second portable computing device over an intervening ad hoc network; and

communication routines running on at least one of the first portable computing device and the particular second portable computing device for enabling person-to-person communication between the first user of the first portable computing device and a second user of the particular second portable computing device, the enabling being performed in response to the targeting determination being affirmative.

2. The system of claim 1 wherein at least one of the first location sensor and the second location sensor is a GPS transducer.

3. The system of claim 1 wherein the orientation sensor includes a magnetometer.

4. The system of claim 1 wherein location data for each of the plurality of second portable computing devices is repeatedly received by the first portable computing device over the intervening ad-hoc network.

5. The system of claim 1 wherein profile information associated with at least one of the first portable computing device and the first user is sent to the particular second portable computing device in response to the targeting determination being affirmative.

6. The system of claim 5 wherein a representation of the profile information is displayed upon a display of the particular second portable computing device.

7. The system of claim 6 wherein the profile information includes an indication of the relative location of the first portable computing device with respect to the particular second portable computing device.

8. The system of claim 1 wherein the second user of the particular second portable computing device is required to affirmatively accept person-to-person communication with the first portable computing device by entering input into the second portable computing device in order to enable real-time person-to-person voice communication between the first portable computing device and the particular second portable computing device.

9. The system of claim 1 wherein the targeting routines perform mathematical operations that determine whether a vector starting from a first spatial location of the first portable computing device and extending in a direction of the user aiming portion is within a certain proximity of a second spatial location of the particular second portable computing device.

10. The system of claim 9 wherein the direction of the aiming portion is a direction of the aiming portion at a time corresponding substantially with when the first user engages a targeting user interface of the first portable computing device.

11. The system of claim 10 wherein the targeting user interface is a button upon the first portable computing device.

12. The system of claim 9 wherein the targeting routines determine whether a vector starting from the first spatial location of the first portable computing device and extending in a direction of the aiming portion comes closer to the second spatial location of the particular second portable computing device than to other second portable computing devices of the plurality of second portable computing devices.

13. The system of claim 1 wherein an enabled person-to-person communication includes a bidirectional voice conversation transmitted over a wireless network.

14. The system of claim 1 wherein an enabled person-to-person communication includes a text message transmitted over a wireless network from the first portable computing device to the particular second portable computing device.

15. A method of providing pointing initiated person-to-person communication, comprising:

detecting a location and pointing orientation of a first portable computing device of a first user, the pointing orientation being associated with an aiming portion of the first portable computing device;

receiving substantially current location data for a second portable computing device over an intervening ad-hoc network, the second portable computing device being associated with a second user;

determining, using at least the detected location and pointing orientation of the first portable computing device and the received location data of the second portable computing device, whether the second portable computing device was substantially pointed at by the aiming portion of the first portable computing device; and

communicating a message from the first user of the first portable computing device to a second user of the second portable computing device in response, at least in part, to the determining.

16. The method of claim 15 wherein the second portable computing device is determined to be substantially pointed at in response to its location data falling within at least one of a defined mathematical area and volume extending approximately from the first portable computing device in a direction of the aiming portion.

17. The method of claim 16 wherein the at least one of the area and volume is at least one of approximately wedge-shaped and cone-shaped.

18. The method of claim 15 wherein the determining is performed at least in part in response to the first user engaging a targeting user interface of the first portable computing device.

19. The method of claim 18 wherein the engaging a targeting user interface comprises the first user manually engaging a control of the first portable computing device in response to the first portable computing device being desirably aimed.

20. The method of claim 19 wherein the control is a button.

21. The method of claim 15 wherein the determining includes an assessment that the second portable computing device is closer to the first portable computing device than a third portable computing device is to the first portable computing device.

22. The method of claim 15 wherein the determining includes an assessment that the second portable computing device is closer to a mathematical vector extending from the first portable computing device in an aiming direction than a third portable computing device is to the mathematical vector.

23. A method of providing pointing initiated person-to-person communication, comprising:

detecting a first location and pointing orientation of a first portable computing device of a first user, the pointing orientation being associated with an aiming portion of the first portable computing device;
