Abstract

A system includes a presentation subsystem, at least one communications port to receive communications from at least one headset, a processor to process the communications and to produce an aggregated audience response to a presentation on the presentation system, and a status communications module to present the aggregated audience response to a presenter. A computer-controlled method of monitoring interest levels receives at least two signals containing brain wave data for at least one user during a presentation, analyzes the brain wave data to determine a mental state for each user, aggregates the mental states into an aggregate mental state for an audience, and provides the aggregate mental state to a presenter.

Claims

1. A system, comprising:

a presentation subsystem to allow a presenter to provide a presentation to an audience;

at least one communications port to receive communications from at least one headset worn by a at least one member of the audience;

a processor to process the communications and to produce an aggregated audience response indicating audience interest level in response to [a] the presentation on the presentation system; and

a status communications module to present the aggregated audience response to a presenter at least partially during the presentation.

2. The system of claim 1, wherein the subsystem further comprises a computer having a display, the computer linked to a projector and the status display is displayed on the display.

3. The system of claim 2, wherein the projector further comprises a video projector.

4. The system of claim 1, wherein the processor synchronizes the aggregated audience response to portions of the presentation.

5. The system of claim 1, wherein the portions of the presentation further comprise at least one selected from the group comprised of:

slides, video frames, still photographs, audio, and pages of text.

6. The system of claim 1, wherein the processor processes the communications in parallel.

7. The system of claim 1, wherein the status display presents the aggregated audience response associated with a portion of the presentation during a time period in which the portion is being presented at least in part.

8. The system of claim 1, wherein the system further comprises a memory to store statistics associated with the presentation.

9. The system of claim 8, wherein the memory is further to store statistics and the presentation in a synchronized format.

10. The system of claim 1, wherein the communications port further comprises a network port for receiving communications from headsets across a network.

11. The system of claim 1, wherein the communications port further comprises a wireless port for receiving communication from one of either the wireless headsets directly, or through a user computer in communication with the wireless headsets.

12-17. -17. (canceled)

18. A system, comprising:

a presentation system;

a communications port for receiving transmissions of user brain activity from a plurality of sources during a presentation occurring on the presentation system;

a processor to extract data from the transmissions of user brain activity and to classify the data as mental states of the users to determine a level of interest in response to the presentation; and

a status display to provide a presenter with an aggregate audience response indicating the level of interest in response to the presentation based upon the mental states of the users.

19. The system of claim 18, the system further comprising a memory to store the data and the presentation.

20. The system of claim 18, the communications port to receive transmissions across a network from the plurality of sources.
