Abstract

Systems and methods of conducting collaborative sessions between mobile devices may provide for determining a time delay associated with a set of participating mobile devices, and determining a command execution time based at least in part on a clock of a managing device and the time delay. One or more control messages may be transmitted to the participating mobile devices, wherein the control messages include the command and the command execution time. Upon receiving a control message, each participating mobile device may determine a local execution time based at least in part on the command execution time and an offset of the clock of the managing device relative to a local clock. Execution of the command can therefore be coordinated across the set of participating mobile devices.

First claim

We claim:

1. An apparatus comprising:
control logic in one or more of a first mobile device and a second mobile device to,
exchange a control message between the first mobile device and the second mobile device over a peer-to-peer connection, wherein the control message includes a command, an execution delay including a timing offset, and a first execution time indicating a time when one of the first mobile device and the second mobile device that generates the control message is to execute the command, and
synchronize with the first execution time a second execution time indicating a time when the other of the first mobile device and the second mobile device that receives the control message is to execute the command, wherein the other of the first mobile device and the second mobile device is to apply the timing offset to the first execution time to determine the second execution time, and

a module in the first mobile device and a module in the second mobile device to execute the command based on the first execution time and the second execution time.

2. The apparatus of claim 1 , wherein the first mobile device and the second mobile device include a camera and the command includes an image capture command.

3. The apparatus of claim 2 , wherein the image capture command is to cause the first mobile device and the second mobile device to synchronously capture a time-sensitive common subject.

4. The apparatus of claim 3 , wherein the module of the first mobile device and the module of the second mobile device are to concurrently execute the image capture command to synchronously capture a time-sensitive common subject.

5. The apparatus of claim 4 , wherein an image to be captured by the first mobile device and an image to be captured by the second mobile device are to be used to generate one or more of a high resolution image and a three-dimensional image.

6. The apparatus of claim 3 , wherein the module of the first mobile device and the module of the second mobile device are to sequentially execute the image capture command to synchronously capture a time-sensitive common subject.

7. The apparatus of claim 1 , wherein the first mobile device and the second mobile device include a display and the command includes an image display command.

8. The apparatus of claim 7 , wherein the image display command is to cause the first mobile device and the second mobile device to synchronously display a time-sensitive common subject.

9. The apparatus of claim 8 , wherein the module of the first mobile device and the module of the second mobile device are to concurrently execute the image display command to synchronously display a time-sensitive common subject.

10. The apparatus of claim 1 , wherein the first mobile device and the second mobile device include a speaker and the command includes an audio output command.

11. A non-transitory computer readable storage medium comprising a set of instructions which, when executed by a processor, cause one or more of a first mobile device and a second mobile device to:
exchange a control message between the first mobile device and the second mobile device over a peer-to-peer connection, wherein the control message includes a command, an execution delay including a timing offset, and a first execution time indicating a time when one of the first mobile device and the second mobile device that generates the control message is to execute the command;
synchronize with the first execution time a second execution time indicating a time when the other of the first mobile device and the second mobile device that receives the control message is to execute the command, wherein the other of the first mobile device and the second mobile device is to apply the timing offset to the first execution time to determine the second execution time; and
execute the command based on the first execution time and the second execution time.

12. The medium of claim 11 , wherein the instructions, when executed, cause the first mobile device and the second mobile to synchronously capture a time-sensitive common subject.

13. The medium of claim 12 , wherein the instructions, when executed, cause the first mobile device and the second mobile device to concurrently execute an image capture command to synchronously capture a time-sensitive common subject.

14. The medium of claim 12 , wherein the instructions, when executed, cause the first mobile device and the second mobile device to sequentially execute an image capture command to synchronously capture a time-sensitive common subject.

15. The medium of claim 11 , wherein the instructions, when executed, cause the first mobile device and the second mobile to synchronously display a time-sensitive common subject.

16. A method comprising:
exchanging a control message between a first mobile device and a second mobile device over a peer-to-peer connection, wherein the control message includes a command, an execution delay including a timing offset, and a first execution time indicating a time when one of the first mobile device and the second mobile device that generates the control message is to execute the command;
synchronizing with the first execution time a second execution time indicating a time when the other of the first mobile device and the second mobile device that receives the control message is to execute the command, wherein the other of the first mobile device and the second mobile device is to apply the timing offset to the first execution time to determine the second execution time; and
executing the command based on the first execution time and the second execution time.

17. The method of claim 16 , wherein the first mobile device and the second mobile synchronously capture a time-sensitive common subject.

18. The method of claim 17 , wherein the first mobile device and the second mobile device concurrently execute an image capture command to synchronously capture a time-sensitive common subject.

19. The method of claim 17 , the first mobile device and the second mobile device sequentially execute an image capture command to synchronously capture a time-sensitive common subject.

20. The method of claim 16 , wherein the first mobile device and the second mobile synchronously display a time-sensitive common subject.
