Abstract

A stimulus compression device determines neuro-feedback significance corresponding to stimulus material and modifies the stimulus material using neuro-feedback significance measures. For example, the stimulus compression device determines portions of a media stream corresponding to low neuro-feedback significance and removes them from the media stream. Compression of stimulus material may involve removal, modification, repetition, bit rate adjustment, resolution adjustment, etc. Transitions can be smoothed or lengthened to further improve processed stimulus material.

Claims

1. A system, comprising:

a data collector to collect first neuro-response data with a first modality and second neuro-response data with a second modality from a subject exposed to an advertisement or entertainment;

a cross-modality response synthesizer to;

align the first neuro-response data and the second neuro-response data by at least one of time shifting or phase shifting at least one of the first neuro-response data or the second neuro-response data; and

combine the first neuro-response data with the second neuro-response data to determine a neuro-feedback significance; and

a compressor to associate the neuro-feedback significance with the advertisement or entertainment and to compress a portion of the advertisement or entertainment based on the neuro-feedback significance.

2. The system of claim 1, wherein the neuro-feedback significance is determined using a combination of neurological and neurophysiological measurements representative of one or more of attention, emotion, or memory retention.

3. The system of claim 1, wherein the neuro-response data includes neurological and neurophysiological response data.

4. The system of claim 1, wherein the advertisement or entertainment is an advertisement stream.

5. The system of claim 4, wherein the compressor is to compress the portion by removing the portion of the advertisement stream corresponding to a low neuro-feedback significance to shorten the advertisement stream.

6. The system of claim 1, wherein the advertisement or entertainment is a motion picture.

7. The system of claim 6, wherein the compressor is to compress the portion by removing the portion of the motion picture corresponding to a low neuro-feedback significance to generate a movie trailer.

8. The system of claim 1, wherein the advertisement or entertainment is a print advertisement.

9. The system of claim 8, wherein the compressor is to compress the portion by removing the portion of the print advertisement corresponding to a low neuro-feedback significance to reduce an area consumed by the print advertisement.

10. The system of claim 1, wherein the advertisement or entertainment is marketing material.

11. The system of claim 1, wherein the compressor is to compress the portion by modifying the portion of the advertisement or entertainment corresponding to a high neuro-feedback significance to highlight an effective portion.

12. The system of claim 1, wherein the cross-modality response synthesizer is to determine the neuro-feedback significance using survey responses.

13. The system of claim 1, wherein the compressor is to compress the portion by removing the portion of the advertisement or entertainment corresponding to a low neuro-feedback significance.

14. The system of claim 1, wherein the compressor is to compress the portion of the advertisement or entertainment using at least one of bit rate or resolution adjustment.

15. The system of claim 1, wherein the compressor is to compress the portion of the advertisement or entertainment using at least one of modification, expansion, or repetition.

20. The system of claim 1, wherein one or more of the first modality or the second modality includes at least one of electroencephalography, electrooculography or galvanic skin response.

21. The system of claim 1, wherein the first neuro-response data includes data from at least one of a central nervous system, an autonomic nervous system or an effector measurement.

24. The system of claim 1, wherein the first and second neuro-response data are gathered during a first portion of the advertisement or entertainment and the compressor is to modify a second portion of the advertisement or entertainment based on the neuro-feedback significance associated with the first portion of the advertisement or entertainment.

16. A method, comprising:

accessing, with a processor, neuro-response data from a subject exposed to an advertisement or entertainment, the neuro-response data including;

(1) first neuro-response data received from a first data collection modality during a first portion of the advertisement or entertainment, and (2) second neuro-response data received from a second data collection modality during the first portion of the advertisement or entertainment;

aligning, with the processor, the first neuro-response data with the second neuro-response data by at least one of time shifting or phase shifting at least one of the first neuro-response data or the second neuro-response data;

determining, with the processor, a first neuro-feedback significance associated with the first portion of the advertisement or entertainment based on the aligned neuro-response data;

identifying, with the processor, if the first neuro-feedback significance is low; and

removing the first portion of the advertisement or entertainment if the first neuro-feedback significance is low.

17. The method of claim 16, wherein the first neuro-feedback significance is determined using one or more of neurological measurements or neurophysiological measurements representative of one or more of attention, emotion, or memory retention.

18. The method of claim 16, wherein the first neuro-response data includes neurological and neurophysiological response data.

22. The method of claim 16 further comprising generating a movie trailer from the advertisement or entertainment.

25. The method of claim 16 further comprising:

determining a second neuro-feedback significance associated with a second portion of the advertisement or entertainment;

identifying the second neuro-feedback significance as high; and

lengthening the second portion.

19. A system, comprising:

means for aligning neuro-response data from a first modality with neuro-response data from a second modality to determine neuro-feedback significance associated with a first portion of an advertisement or entertainment and a second portion of the advertisement or entertainment;

means for identifying the first portion as having low neuro-feedback significance and the second portion as having high neuro-feedback significance; and

means for transmitting the first portion of the advertisement or entertainment at a first bit rate and the second portion of the advertisement or entertainment at a second bit rate based on the identification.

27. The system of claim 19, wherein the second bit rate is higher than the first bit rate.

23. A tangible storage device or storage disc having machine readable instructions stored thereon which, when executed, cause a machine to at least:

determine neuro-feedback significances associated with a plurality of portions of an advertisement or entertainment based on neuro-response data obtained from a subject exposed to the advertisement or entertainment using a plurality of modalities;

repeat a first portion of the portions of the advertisement or entertainment having a high neuro-response feedback significance;

remove a second portion of the portions of the advertisement or entertainment, the second portion corresponding to a low neuro-feedback significance; and

lengthen the first portion or a third portion of the advertisement or entertainment.

26. The method of 19 further comprising:

determining a second neuro-feedback significance associated with a second portion of the advertisement or entertainment;

identifying the second neuro-feedback significance as high; and

repeating the second portion of the advertisement or entertainment.
