Abstract

Location data and/or acceleration data of a mobile device may be received. The data may include timestamps. The timestamped data of the mobile device may be compared to timestamped data of another mobile device. Upon determining the timestamped data of the mobile device matches the timestamped data of the other mobile device, joint movement of the mobile devices may be signaled.

Claims

1. A method for determining joint movement of multiple mobile devices, the method comprising:

receiving one of location data and acceleration data of a mobile device, the received data including timestamps;

comparing the timestamped data of the mobile device to timestamped data of another mobile device;

upon determining the timestamped data of the mobile device matches the timestamped data of the other mobile device, signaling joint movement of the mobile devices, wherein timestamped data of the mobile device and the timestamped data of the other mobile device are one of

     1) synchronized and

     2) not synchronized.

2. A method for determining joint movement of multiple mobile devices, the method comprising:

receiving one of location data and acceleration data of a mobile device, the data including timestamps;

comparing the timestamped data of the mobile device to timestamped data of another mobile device;

upon determining the timestamped data of the mobile device matches the timestamped data of the other mobile device, signaling joint movement of the mobile devices.

3. The method according to claim 2, wherein the timestamped data of the mobile device is received at predefined intervals.

4. The method according to claim 2, wherein the timestamped data of the mobile device and the timestamped data of the other mobile device are synchronized.

5. The method according to claim 2, wherein the timestamped data of the mobile device and the timestamped data of the other mobile device are not synchronized.

6. The method according to claim 5, wherein the timestamped data of the mobile device and the timestamped data of the other mobile device are matched based on a time shift.

7. The method according to claim 2, wherein the timestamped data of the mobile device and the timestamped data of the other mobile device are matched within a tolerance level.

8. An apparatus comprising:

a processor to;

receive one of location data and acceleration data of a mobile device, the data including timestamps;

compare the timestamped data of the mobile device to timestamped data of another mobile device;

upon determining the timestamped data of the mobile device matches the timestamped data of the other mobile device, signal joint movement of the mobile devices.

9. The apparatus of claim 8, wherein the timestamped data of the mobile device is received at predefined intervals.

10. The apparatus of claim 8, wherein the timestamped data of the mobile device and the timestamped data of the other mobile device are synchronized.

11. The apparatus of claim 8, wherein the timestamped data of the mobile device and the timestamped data of the other mobile device are not synchronized.

12. The apparatus of claim 11, wherein the timestamped data of the mobile device and the timestamped data of the other mobile device are matched based on a time shift.

13. The apparatus of claim 8, wherein the timestamped data of the mobile device and the timestamped data of the other mobile device are matched within a tolerance level.

14. A non-transitory computer-readable medium embodied with computer-executable instructions for causing a computer to execute instructions, the computer instructions comprising:

receiving one of location data and acceleration data of a mobile device, the data including timestamps;

comparing the timestamped data of the mobile device to timestamped data of another mobile device;

upon determining the timestamped data of the mobile device matches the timestamped data of the other mobile device, signaling joint movement of the mobile devices.

15. The computer-readable medium of claim 14, wherein the timestamped data of the mobile device is received at predefined intervals.

16. The computer-readable medium of claim 14, wherein the timestamped data of the mobile device and the timestamped data of the other mobile device are synchronized.

17. The computer-readable medium of claim 14, wherein the timestamped data of the mobile device and the timestamped data of the other mobile device are not synchronized.

18. The computer-readable medium of claim 17, wherein the timestamped data of the mobile device and the timestamped data of the other mobile device are matched based on a time shift.

19. The computer-readable medium of claim 14, wherein the timestamped data of the mobile device and the timestamped data of the other mobile device are matched within a tolerance level.
