Abstract

A method is described for manipulating a view displayed on one or more follower participants'"'"' devices to track a view displayed on a lead participant'"'"'s device. A request to manipulate the view displayed on the one or more follower participant devices is received. The lead participant is identified. The follower participants are identified. A lead view of the lead participant is determined. The lead view is communicated to the follower participants computing devices for display. A computing device and a non-transitory computer readable medium having instructions configured to implement the method are also described.

Claims

1. A method for manipulating a view displayed on one or more follower participants'"'"' devices to track a view displayed on a lead participant'"'"'s device, the method comprising:

receiving a request to manipulate the view displayed on the one or more follower participant devices;

identifying the lead participant;

identifying the follower participants;

determining a lead view of the lead participant; and

communicating the lead view to the follower participants computing devices for display.

2. The method of claim 1, wherein the lead participant and the follower participants are identified from the request.

3. The method of claim 1 further comprising repeatedly communicating the lead view to the follower participants computing devices until a release request is received.

4. The method of claim 3, wherein the lead view is communicated to the follower participants until the release request is confirmed.

5. The method of claim 4, wherein the release request identifies which of one or more of the follower participant to cease communicating the lead view.

6. The method of claim 1 further comprising continuing to process input received from one or more of the follower participants within the lead view.

7. The method of claim 3 further comprising storing the view displayed on one or more of the follower participants'"'"' devices prior to communicating the lead view.

8. The method of claim 7 further comprising communicating the stored view to the follower participants when the release request is received.

9. The method of claim 1 further comprising transmitting a permission request to the follower participants computing devices and only communicating the lead view when the permission request is accepted.

10. The method of claims 9 further comprising determining whether to transmit the permission request based on a type of the request to manipulate the view displayed.

11. The method of claim 1, wherein the request is received from the lead participant'"'"'s device or from one of the follower participants'"'"' devices.

12. A non-transitory computer readable medium having stored thereon instructions which, when executed by a computing device, cause the computing device to:

receive a request to manipulate the view displayed on the one or more follower participant devices;

identify the lead participant;

identify the follower participants;

determine a lead view of the lead participant; and

communicate the lead view to the follower participants computing devices for display.

13. The non-transitory computer readable medium of claim 12, wherein the lead participant and the follower participants are identified from the request.

14. The non-transitory computer readable medium of claim 12 further comprising instructions to repeatedly communicate the lead view to the follower participants computing devices until a release request is received.

15. The non-transitory computer readable medium of claim 14, wherein the lead view is communicated to the follower participants until the release request is confirmed.

16. The non-transitory computer readable medium of claim 15, wherein the release request identifies which of one or more of the follower participant to cease communicating the lead view.

18. The non-transitory computer readable medium of claim 14 further comprising instructions to store the view displayed on one or more of the follower participants'"'"' devices prior to communicating the lead view.

19. The non-transitory computer readable medium of claim 18 further comprising instructions to communicate the stored view to the follower participants when the release request is received.

20. The non-transitory computer readable medium of claim 12 further comprising instructions to transmit a permission request to the follower participants computing devices and only communicate the lead view when the permission request is accepted.

21. The non-transitory computer readable medium of claims 20 further comprising instructions to determine whether to transmit the permission request based on a type of the request to manipulate the view displayed.

22. The non-transitory computer readable medium of claim 12, wherein the request is received from the lead participant'"'"'s device or from one of the follower participants'"'"' devices.

17. The non-transitory computer readable medium 12 of claim further comprising continuing to process input received from one or more of the follower participants within the lead view.

23. A computing device comprising:

a communication interface for communicating with other computing devices;

memory for storing instruction; and

a processor configured to execute the instructions, which cause the computing device to;

receive a request to manipulate the view displayed on the one or more follower participant devices;

identify the lead participant;

identify the follower participants;

determine a lead view of the lead participant; and

communicate the lead view to the follower participants computing devices for display.
