Abstract

The present invention relates to systems and methods for providing screen sharing techniques to selectively share portions of the screen between a source node and a consumer node. The source node, such as the computer of a presenter of an online meeting, may transmit screen data to a consumer node, such as the computer of an attendee of the online meeting. The consumer or attendee computer uses the screen data to display the screen of the source or presenter'"'"'s computer. The techniques of the present invention provide a mechanism for not sharing a selective portion of the presenter'"'"'s screen during screen sharing. So, although a certain element may be displayed on the screen of the presenter, the present invention prevents an attendee from viewing the user interface element in the screen share session.

Claims

1. A method for selectively sharing screen data between a first computing device and a second computing device, the second computing device displaying screen data of the first computing device, the method comprising the steps of:

(a) transmitting screen data displayed by the first computing device to a second computing device, the screen data including a user interface element having a deployed state and an undeployed state;

(b) detecting that the user interface element is in the deployed state; and

(c) suspending transmission of screen data to the second computing device.

2. The method of claim 1, further comprising the steps of:

(d) detecting the user interface element transitioned from the deployed state to the undeployed state; and

(e) resuming transmission of screen data to the second computing device.

3. The method of claim 1, further comprising the step of displaying by the first computing device an indication that transmission of screen data to the second computing device is suspended.

4. The method of claim 1, wherein the user interface element comprises a user interface element selected from the group consisting of:

a control panel, a dialog, a popup menu, a tool tip, a chat bubble, and a system bubble.

5. The method of claim 1, wherein the user interface element comprises a communication selected from the group consisting of:

a private, a sensitive, and a confidential communication of a user.

6. The method of claim 1, further comprising detecting a change to the first computing device'"'"'s screen during the suspension of transmission of screen data.

7. The method of claim 6, further comprising queuing a portion of screen data representing the screen change.

8. The method of claim 7, further comprising discarding the portion of screen data after a predetermined time period.

9. The method of claim 7, further comprising transmitting the portion of screen data to the second computing device upon resuming transmission of screen data.

10. The method of claim 1, comprising representing portions of the first computing device'"'"'s screen as a plurality of tiles.

11. The method of claim 10, detecting a change to a first tile of the plurality of tiles, and providing a data packet for transmission to the second computing device, the data packet representing the change to the first tile.

12. The method of claim 11, wherein transmitting further comprises synchronizing the data packet with the second computing device using a bandwidth-adaptive mechanism.

13. The method of claim 1, wherein the undeployed state comprises the user interface element being one of minimized or not displayed.

14. A system for selectively sharing screen data between a first computing device and a second computing device, the second computing device displaying screen data of the first computing device, the system comprising:

a transmitter for transmitting screen data displayed by a first computing device to a second computing device, the screen data including a user interface element having a deployed state and an undeployed state;

a detector for detecting a state of the user interface element; and

wherein in response to the detector detecting the user interface element is in the deployed state, the transmitter suspends transmission of screen data to the second computing device.

15. The system of claim 14, wherein the detector detects the user interface element transitioning from the deployed state to the undeployed state, and in response to the detector, the transmitter resumes transmission of screen data to the second computing device.

16. The system of claim 14, comprising an indicator displayed on the first computing device identifying the suspension of transmission of screen data to the second computing device.

17. The system of claim 14, wherein the user interface element comprises a user interface element selected from the group consisting of:

a control panel, a dialog, a popup menu, a tool tip, a chat bubble, and a system bubble.

18. The system of claim 14, wherein the user interface element comprises a communication selected from the group consisting of:

a private, a sensitive, or a confidential communication of a user.

19. The system of claim 14, comprising a screen change detector detecting a screen change during the suspension of transmission of screen data.

20. The system of claim 19, comprising a queuing mechanism for queuing screen data, the queuing mechanism queuing a portion of screen data representing the screen change.

21. The system of claim 20, wherein the queuing mechanism discards the portion of screen data after a predetermined time period.

22. The system of claim 20, wherein the transmitter transmits the portion of screen data to the second computing device upon resuming transmission of screen data.

23. The system of claim 16, comprising a plurality of tiles representing portions of the first computing device'"'"'s screen.

24. The system of claim 23, comprising a screen change detector detecting a change to a portion of the screen represented by a first tile of the plurality of tiles.

25. The system of claim 24, comprising a data packet for transmission to the second computing device, the data packet comprising a representation of the change to the first tile.

26. The system of claim 25, wherein the transmitter comprises a bandwidth-adaptive mechanism to synchronize the data packet with the second computing device.

27. The system of claim 14, wherein the undeployed state of the user interface element comprises one of minimized or not displayed.

28. A system for selectively sharing screen data between a first computing device and a second computing device, the second computing device displaying screen data of the first computing device, the system comprising:

a means for transmitting screen data displayed by a first computing device to a second computing device, the screen data including a user interface element having a deployed state and an undeployed state;

a means for detecting a state of the user interface element; and

a means for suspending transmission of screen data to the second computing device in response to detecting the user interface element is in the deployed state.

29. The system of claim 28, comprising a means for detecting the user interface element transitioning from the deployed state to the undeployed state, and a means for resuming the transmission of screen data to the second computing device.

30. The system of claim 28, comprising a means for providing an indicator displayed on the first computing device identifying the suspension of the transmission of screen data to the second computing device.

31. The system of claim 28, wherein the user interface element comprises a user interface element selected from the group consisting of:

a control panel, a dialog, a popup menu, a tool tip, a chat bubble, and a system bubble.

32. The system of claim 28, wherein the user interface element comprises a communication selected from the group consisting of:

a private, a sensitive, or a confidential communication of a user.

33. The system of claim 28, comprising a means for detecting a change to the first computing device'"'"'s screen during the suspension of transmission of screen data.

34. The system of claim 28, comprising a means for queuing a portion screen data representing the screen change
