Abstract

Techniques are disclosed for detecting knowledge based on brainwave response to external stimulation. A subject can be exposed to stimuli and brainwave responses indicating a p-300 signal can be detected. Further stimuli or sequences of stimuli can be selected be presented to the subject based on the category correlated with the stimuli that indicate a p-300 response.

Claims

1. A method comprising:

exposing a subject to a first sequence of stimuli, at least one stimulus of the first sequence of stimuli correlated with a category;

detecting a brainwave response of the subject to the at least one stimulus of the first sequence of stimuli;

correlating the detected brainwave response to at least one target category; and

selecting a second sequence of stimuli, based upon the brainwave response of the subject to the at least one stimulus of the first sequence of stimuli.

2. The method of claim 1, wherein detected brainwave response is a p-300 signal.

3. The method of claim 1, wherein the at least one stimulus of the first sequence of stimuli is selected from the group consisting of:

a sight stimulus, a sound stimulus, a touch stimulus, a smell stimulus, and a taste stimulus.

4. The method of claim 1, wherein the at least one target category is an occupational category.

5. The method of claim 1, wherein the first sequence of stimuli is presented to the subject at a rate of at least 3 stimuli per second.

6. The method of claim 1, wherein the first sequence of stimuli is a baseline sequence.

7. The method of claim 1, wherein the selecting the second sequence of stimuli is performed by a user.

8. The method of claim 1, wherein at least one stimulus of the second sequence of stimuli is correlated with a less abstract category than the category correlated with the at least one stimulus of the first sequence of stimuli.

9. The method of claim 1, wherein the detecting the brainwave response is performed through an electroencephalograph (EEG).

10. The method of claim 1, wherein each stimulus of the first sequence of stimuli are correlated with a target category or non-target category.

11. A system comprising:

at least one sensor;

a presentation device; and

a processor in communication with the presentation device and the at least one sensor and adapted and configured to send at least one stimulus in a first sequence of stimuli to the presentation device, receive a brainwave response from the at least one sensor based upon the brainwave response of a subject, correlate the received brainwave response to at least one target category, and select a second sequence of stimuli, based upon the brainwave response of the subject to the at least one stimulus of the first sequence of stimuli.

12. The system of claim 11, wherein received brainwave response is a p-300 signal.

13. The system of claim 11, wherein each stimulus of the first sequence of stimuli is selected from the group consisting of:

a sight stimuli, a sound stimuli, a touch stimuli, a smell stimuli, and a taste stimuli.

14. The system of claim 11, wherein the at least one target category is an occupational category.

15. The system of claim 11, wherein the presentation device exposes the subject to the first sequence of stimuli at a rate of at least 3 stimuli per second.

16. The system of claim 11, wherein the first sequence of stimuli is a baseline sequence.

17. The system of claim 11, wherein a user controls the processor to select the second sequence of stimuli.

18. The system of claim 11, wherein at least one stimulus of the second sequence of stimuli is correlated with a less abstract category than a category correlated with the at least one stimulus of the first sequence of stimuli.

19. The system of claim 11, wherein at least one sensor is an electrode of an EEG.

20. The system of claim 11, wherein each stimulus of the first sequence of stimuli is correlated with a target category or non-target category.
