Abstract

A system for supporting virtual conferences includes a switching center, a virtual conference database and a virtual conference bridge. The virtual conference database stores virtual conference information comprising, for example, images associated with a room type, an outdoor environment, a presentation medium and/or a meeting room facility. The switching center is operable to set up a virtual conference including a host terminal and one or more participating terminals by connecting the terminals to the conference bridge, retrieving selected virtual conference information from the virtual conference database and sending the information to the virtual conference bridge. The virtual conference information includes images of the participants such that the host terminal and participating terminals see and hear other participants in a virtual meeting room.

Claims

1. A method comprising the steps of:

receiving, from a host terminal, a request to set up a virtual conference, the virtual conference defining a communication forum for communicating virtual conference information among a plurality of virtual reality terminals including the host terminal, the virtual conference information including one or more virtual images;

determining selected attributes of the virtual conference;

retrieving information supporting the selected attributes;

removing an extraneous portion of the information, yielding filtered information and supplementing one or more of the information and filtered information with supplemental information, the information, filtered information and supplemental information defining the virtual conference information;

sending at least a portion of the virtual conference information to a virtual conference bridge; and

connecting the host terminal to the virtual conference bridge, thereby setting up the virtual conference including initially the host terminal.

2. The method of claim 1, wherein the step of retrieving information comprises retrieving a portion of the virtual conference information from a virtual conference database.

3. The method of claim 1, wherein the step of retrieving information comprises retrieving a portion of the virtual conference information from the host terminal, the virtual conference information including one or more facial images of a host operating the host terminal.

4. The method of claim 1, wherein the step of determining selected attributes comprises receiving indicia of options selected via the host terminal.

5. The method of claim 4, wherein the step of receiving indicia of options comprises receiving indicia of a selected room type, the step of retrieving information comprising retrieving information associated with the selected room type from a virtual conference database.

6. The method of claim 4, wherein the step of receiving indicia of options comprises receiving indicia of a selected outdoor environment, the step of retrieving information comprising retrieving information associated with the selected outdoor environment from a virtual conference database.

7. The method of claim 4, wherein the step of receiving indicia of options comprises receiving indicia of a selected presentation medium, the step of retrieving information comprising retrieving information associated with the selected presentation medium from a virtual conference database.

8. The method of claim 4, wherein the step of receiving indicia of options comprises receiving indicia of a selected meeting room facility, the step of retrieving information comprising retrieving information associated with the selected meeting room facility from a virtual conference database.

9. The method of claim 1, further comprising:

receiving, from at least one participating terminal, a request to join the virtual conference; and

connecting the at least one participating terminal to the virtual conference bridge, thereby joining the at least one participating terminal to the virtual conference.

10. The method of claim 9, wherein the step of retrieving information comprises retrieving information from one or more of:

the virtual conference database, the host terminal and the at least one participating terminal, the information from the host terminal and the at least one participating terminal including facial images of operators of the host terminal and the at least one participating terminal.

11. The method of claim 10, wherein the step of removing an extraneous portion of the information comprises removing extraneous information retrieved from one or more of:

the virtual conference database, the host terminal and the at least one participating terminal.

12. The method of claim 11, wherein the step of supplementing comprises overwriting at least a portion of the filtered information.

13. The method of claim 10, wherein the step of supplementing comprises overwriting at least a portion of the information retrieved from one or more of:

the virtual conference database, the host terminal and the at least one participating terminal.

14. A method comprising:

establishing a virtual conference comprising a host virtual reality terminal and one or more participating virtual reality terminals connected to a virtual conference bridge;

communicating virtual conference information including one or more virtual images among the host terminal and one or more participating terminals via the virtual conference bridge, the virtual images including images retrieved from one or more of;

the host terminal, the one or more participating terminals and a virtual conference database; and

one or more of;

images derived by removing extraneous information from the retrieved images, defining filtered images;

images derived by overwriting the retrieved images with supplemental information; and

images derived by overwriting the filtered images with supplemental information.

15. The method of claim 14, wherein the step of communicating virtual conference information comprises sending images associated with a selected room type to the host terminal and one or more participating terminals.

16. The method of claim 14, wherein the step of communicating virtual conference information comprises sending images associated with a selected outdoor environment to the host terminal and one or more participating terminals.

17. The method of claim 14, wherein the step of communicating virtual conference information comprises sending images associated with a selected presentation medium to the host terminal and one or more participating terminals.

18. The method of claim 14, wherein the step of communicating virtual conference information comprises sending images associated with a selected meeting room facility to the host terminal and one or more participating terminals.

19. A system comprising:

a switching center;

a virtual conference database; and

a virtual conference bridge,

the switching center being operable to retrieve virtual conference information including one or more virtual images from the virtual conference database and send the information to the virtual conference bridge, the switching center further being operable to connect a host virtual reality terminal and one or more participating virtual reality terminals to the virtual conference bridge, thereby establishing a virtual conference where the host terminal and participating terminals may receive the virtual conference information;

the virtual images including images retrieved from one or more of;

the host virtual reality terminal, the one or more participating virtual reality terminals and the virtual conference database; and

one or more of;

images derived by removing extraneous information from the retrieved images, defining filtered images;

images derived by overwriting the retrieved images with supplemental information; and

images derived by overwriting the filtered images with supplemental information.

20. The system of claim 19 wherein the virtual conference information comprises images associated with one or more of a room type, an outdoor environment, a presentation medium and a meeting room facility, the switching center being operable to retrieve selected images from the virtual conference database and send the selected images to the virtual conference bridge, the host terminal and participating terminals receiving the images upon connection to the virtual conference bridge.
