Abstract

An online environment server hosts an event, such as a class period or interactive entertainment event, in a virtual reality process. Clients are divided into groups as they join the process according to defined group and user profiles and current group capacities. A human host, such as a teaching assistant, may also join each group as a moderator or administrator. Each group member interacts in real time with other group members via electronic chat. Recordings of group sessions may be accessed later by non-group members. The group server is configured such that the group moderator or administrator may control classroom data flow for her assigned group, such as pausing an animated stream of instructor or event input into the virtual classroom to allow classroom questions or discussion, causing the stream to be cached at the system level. Then, the moderator may resume play of the instructional sequence. When resuming play after a pause, the system server may automatically speed up play of the animated input stream from a cache while continuing to cache as necessary, until parity is reached with the current input stream for all groups.

Claims

1. A method comprising:

receiving, at a server, input from multiple clients to model a virtual reality classroom in which input from at least one designated instructor client and input from designated student ones of the multiple clients are processed to control animated video and audio output of a multi-user modeled three-dimensional virtual reality classroom;

modeling, at the server, a common environment portion of the virtual reality classroom responsive to input from the instructor client;

modeling, at the server, at least two separate and distinct student group portions of the virtual reality classroom each responsive to input from different subsets of the student ones of the multiple clients;

transmitting a first data stream from the server to a first one of the different subsets, configured for modeling the common environment portion and a first one of the at least two separate student group portions of the virtual reality classroom;

while

substantially simultaneously transmitting a second data stream from the server to a second one of the different subsets, configured for modeling the common environment portion and a second one of the at least two separate student group portions of the virtual reality classroom.

2. The method of claim 1, further comprising transmitting a third data stream to the at least one designated instructor client, configured for modeling each of the at least two separate and distinct student group portions of the virtual reality classroom.

3. The method of claim 1, further comprising receiving input from designated moderator clients distinct from the instructor and student clients, for each of the at least two separate and distinct student group portions of the virtual reality classroom.

4. The method of claim 3, further comprising processing input from the designated moderator clients to enable moderator control of the common environment portions of the first and second data streams.

5. The method of claim 4, wherein the moderator control includes enabling pausing of video and audio output in the common environment portions at each of the student ones of the multiple clients.

6. The method of claim 5, wherein the moderator control further includes enabling resuming play of video and audio output at each of the student ones of the multiple clients, after the video and audio output is paused.

7. The method of claim 5, wherein the server resynchronizes play of the common environment portions of the first and second data streams after one of the common environment portions is paused, by altering relative rates of play of the common environment portions until the portions are substantially synchronous with each other.

8. The method of claim 1, further comprising serving first chat data enabling chat between members of the first one of the different subsets, and second chat data enabling chat between members of the second one of the different subsets.

9. The method of claim 8, wherein the first and second chat data comprises audio chat data.

10. The method of claim 8, wherein the first and second chat data comprises text chat data.

11. The method of claim 8, further comprising enabling chat between the instructor client and the first one of the different subsets by the first chat data, and enabling chat between the instructor client and the second one of the different subsets by the second chat data.

12. The method of claim 8, further comprising enabling chat between a first one of the moderator clients and the first one of the different subsets by the first chat data, and enabling chat between a second one of the moderator clients and the second one of the different subsets by the second chat data.

13. The method of claim 12, further comprising enabling the chat with the moderator clients while pausing play of the common environment portion.

14. The method of claim 1, further comprising maintaining synchronization between the common environment portions of the first and second data streams.

15. The method of claim 1, further comprising spawning a new student group portion of the virtual reality classroom each responsive to input from a new subset of the student ones of the multiple clients, in response to an increase in number of the student ones of the multiple clients.

16. The method of claim 1, further comprising assigning the student ones of the multiple clients to each of the subsets in response to parameter data describing student characteristics.

17. A computer-readable medium encoded with instructions for causing a computer processor to:

model a virtual reality classroom in response to input from at least one designated instructor client and input from designated student clients to provide animated video and audio output for a multi-user modeled three-dimensional virtual reality classroom, wherein the virtual reality classroom comprises a common environment portion responsive to input from the instructor client and at least two separate and distinct student group portions responsive to input from different subsets of the student clients;

transmit a first data stream from the server to a first one of the different subsets, configured for modeling the common environment portion and a first one of the at least two separate student group portions of the virtual reality classroom;

while

substantially simultaneously transmitting a second data stream from the server to a second one of the different subsets, configured for modeling the common environment portion and a second one of the at least two separate student group portions of the virtual reality classroom.

18. The computer-readable medium of claim 17, further comprising instructions for causing a computer processor to independently pause respective ones of the common environment portions in response to moderator input.

19. The computer-readable medium of claim 18, further comprising instructions for causing a computer processor to resynchronize play of the respective ones of the common environment portions in response to receiving input indicating termination of a pause event.

20. A virtual reality classroom system, comprising:

means for modelling a virtual reality classroom in response to input from at least one designated instructor client and input from designated student clients to provide animated video and audio output for a multi-user modeled three-dimensional virtual reality classroom, wherein modeling provides the virtual reality classroom comprising a common environment portion responsive to input from the instructor client and at least two separate and distinct student group portions responsive to input from different subsets of the student clients; and

means for providing a first data stream from the server to a first one of the different subsets, configured for modeling the common environment portion and a first one of the at least two separate student group portions of the virtual reality classroom while substantially simultaneously transmitting a second data stream from the server to a second one of the different subsets, configured for modeling the common environment portion and a second one of the at least two separate student group portions of the virtual reality classroom.
