Abstract

Techniques for optimizing desktop sharing for wireless clients during web collaboration are presented. In one embodiment, a computer-implemented method comprises determining that a presenter of a collaborative online meeting is using a desktop sharing session, determining that one or more attendees participating in the collaborative online meeting are using devices with limited display capabilities, determining a particular window displayed on the desktop of the presenter of the desktop sharing session, and causing transmission of only data from the particular window displayed on the desktop of the presenter to the one or more devices.

Claims

1. A computer-implemented method, comprising:

at an online meeting server, coupled to a presenter and a plurality of attendees;

determining that the presenter of a collaborative online meeting is using a desktop sharing session;

determining that one or more attendees, from the plurality of attendees, who are participating in the collaborative online meeting, are using respective one or more devices with limited display capabilities;

determining, from among a plurality of graphical user interface windows that are then-currently displayed on a desktop of the presenter of the desktop sharing session, a particular window that is one of a plurality of windows; and

causing transmission of only data from the particular window displayed on the desktop of the presenter to the one or more devices;

determining that a word processing application program is associated with the particular window;

causing one or more devices to receive only text characters of a word processing document that is displayed in the particular window.

2. The computer-implemented method of claim 1, further comprising generating a graphical image bitmap of only the particular window.

3. The computer-implemented method of claim 1, further comprising transforming the data from the particular window into a structured document format prior to causing the one or more devices to receive the data.

4. The computer-implemented method of claim 3, wherein the structured document format is hypertext markup language (HTML).

5. The computer-implemented method of claim 1, further comprising generating a graphical image bitmap of only the particular window and excluding one or more toolbars, icons and graphical widgets of the particular window.

6. The computer-implemented method of claim 1, further comprising receiving one or more messages from a server to which the attendees and the presenter are coupled.

7. The computer-implemented method of claim 1, further comprising calling an application programming interface function of an operating system of a computer of the presenter.

19. The computer-implemented method of claim 1, wherein the particular window is a top-most window of the plurality of windows.

20. The computer-implemented method of claim 1, wherein the particular window is an active window of the plurality of windows.

25. The computer-implemented method of claim 1, further comprising determining which application program among a plurality of application programs is associated with the particular window.

8. A non-transitory computer-readable storage medium storing one or more sequences of instructions which, when executed by one or more processors, cause the one or more processors to perform:

at an online meeting server, coupled to a presenter and a plurality of attendees;

determining that the presenter of a collaborative online meeting is using a desktop sharing session;

determining that one or more attendees, from the plurality of attendees, who are participating in the collaborative online meeting, are using respective one or more devices with limited display capabilities;

determining, from among a plurality of graphical user interface windows that are then-currently displayed on a desktop of the presenter of the desktop sharing session, a particular window that is one of a plurality of windows; and

,

causing transmission of only data from the particular window displayed on the desktop of the presenter to the one or more devices;

determining that a word processing application program is associated with the particular window; and

causing the one or more devices to receive only text characters of a word processing document that is displayed in the particular window.

9. The storage medium of claim 8, further comprising instructions which, when executed, cause generating a graphical image bitmap of only the particular window.

10. The storage medium of claim 8, further comprising instructions which, when executed, cause transforming the data from the particular window into a structured document format prior to causing the one or more devices to receive the data.

11. The storage medium of claim 10, wherein the structured document format is hypertext markup language (HTML).

12. The storage medium of claim 8, further comprising instructions which, when executed, cause generating a graphical image bitmap of only the particular window and excluding one or more toolbars, icons and graphical widgets of the particular window.

13. The storage medium of claim 8, wherein the instructions which, when executed, cause determining that the one or more attendees are using respective one or more devices with limited display capabilities further comprise instructions which, when executed, cause receiving one or more messages from the online server to which the attendees and the presenter are coupled.

14. The storage medium of claim 8, wherein the instructions which, when executed, cause determining the particular window that is one of the plurality of windows further comprise instructions which, when executed, cause calling an application programming interface function of an operating system of a computer of the presenter.

21. The computer-readable storage medium of claim 8, wherein the particular window is a top-most window of the plurality of windows.

22. The computer-readable storage medium of claim 8, wherein the particular window is an active window of the plurality of windows.

26. The storage medium of claim 8, further comprising instructions which when executed cause determining which application program among a plurality of application programs is associated with the particular window.

15. An apparatus, comprising:

one or more processors;

a computer-readable storage medium storing encoded thereon one or more sequences of instructions which, when executed by one or more processors, cause the one or more processors to perform;

at an online meeting server, coupled to a presenter and a plurality of attendees;

determining that the presenter of a collaborative online meeting is using a desktop sharing session rather than an application sharing session;

determining that one or more attendees, from the plurality of attendees, who are participating in the collaborative online meeting, are using respective one or more devices with limited display capabilities;

determining, from among a plurality of graphical user interface windows that are then-currently displayed on a desktop of the presenter of the desktop sharing session, a particular window that is one of a plurality of windows; and

,

causing transmission of only data from the particular window on the desktop of the presenter to the one or more devices;

determining that a word processing application program is associated with the particular window; and

causing one or more devices to receive only text characters of a word processing document that is displayed in the particular window.

16. The apparatus of claim 15, further comprising instructions which, when executed, cause generating a graphical image bitmap of only the particular window.

17. The apparatus of claim 15, further comprising instructions which, when executed, cause transforming the data from the particular window into a structured document format prior to causing the one or more devices to receive the data.

18. The apparatus of claim 15, further comprising instructions which, when executed, cause generating a graphical image bitmap of only the particular window and excluding one or more toolbars, icons and graphical widgets of the particular window.

23. The apparatus of claim 15, wherein the particular window is a top-most window of the plurality of windows.

24. The apparatus of claim 15, wherein the particular window is an active window of the plurality of windows.

27. The apparatus of claim 15, further comprising instructions which when executed cause determining which application program among a plurality of application programs is associated with the particular window.
