Abstract

Biofeedback, including cognitive feedback, may be used to provide real time information about a viewer'"'"'s reaction to an ongoing playback of audio visual content. Cognitive feedback provides electronic feedback related to brain activity. Biofeedback involves using sensed human characteristics to judge a user'"'"'s reaction to audio visual content.

Claims

1. A method comprising:

using biofeedback to electronically modify a computer generated audio or visual presentation.

2. The method of claim 1 wherein using biofeedback includes using a cognitive feedback sensor.

3. The method of claim 1 including selecting between at least two alternative versions of audio visual presentation based on said biofeedback.

4. The method of claim 1 including electronically modifying an ongoing presentation based on said feedback.

5. The method of claim 1 including using biofeedback as an indication of a user'"'"'s reaction to a level of stereoscopic effect.

6. The method of claim 5 including changing the level of stereoscopic effect in response to biofeedback.

7. The method of claim 1 including using biofeedback as an indicator of a user'"'"'s reaction to a level of stereo effect.

8. The method of claim 1 including changing the channel mixing for different speakers based on biofeedback.

9. The method of claim 1 including based on biofeedback from two different viewers, providing different audio visual presentations to each of said viewers.

10. The method of claim 1 including changing frame rate in response to biofeedback.

11. One or more non-transitory computer readable media storing instructions executed by a processor to store a sequence comprising:

using biofeedback to modify an audio or visual presentation.

12. The media of claim 11 further storing instructions to perform a sequence wherein using biofeedback includes using a cognitive feedback sensor.

13. The media of claim 11 further storing instructions to perform a sequence including selecting between at least two alternative versions of audio video presentation based on said biofeedback.

14. The media of claim 11 further storing instructions to perform a sequence including electronically modifying an ongoing presentation based on said feedback.

15. The media of claim 11 further storing instructions to perform a sequence including using biofeedback as an indication of a user'"'"'s reaction to a level of stereoscopic effect.

16. The media of claim 15 further storing instructions to perform a sequence including changing the level of stereoscopic effect in response to biofeedback.

17. The media of claim 11 further storing instructions to perform a sequence including using biofeedback as an indicator of a user'"'"'s reaction to a level of stereo effect.

18. The media of claim 11 further storing instructions to perform a sequence including changing the channel mixing for different speakers based on biofeedback.

19. The media of claim 11 further storing instructions to perform a sequence including based on biofeedback from two different viewers, providing different audio visual presentations to each of said viewers.

20. The media of claim 11 further storing instructions to perform a sequence including changing frame rate in response to biofeedback.

21. The media of claim 11 further storing instructions to drive two user worn shutters differently based on biofeedback from different users.

22. An apparatus comprising:

a cognitive feedback device; and

a computer coupled to said device to modify an ongoing audio or visual presentation based on cognitive feedback.

23. The apparatus of claim 22 wherein said device is a functional near-infrared spectroscopy device.

24. The apparatus of claim 22 wherein said computer to modify a stereo effect.

25. The apparatus of claim 22, said computer to select between two presentations based on said cognitive feedback.

26. The apparatus of claim 22, said computer to elect to manually modify the presentation based on said feedback.

27. The apparatus of claim 26 said computer to modify the frame rate of the presentation.

28. The apparatus of claim 22 including an operating system.

29. The apparatus of claim 22 including a battery.

30. The apparatus of claim 22 including firmware and a module to update said firmware.
