Systems and methods for indexing media files using brainwave signals

1. A method for indexing a media file, the method comprising:

receiving a selected media file;

playing the selected media file on a media device while simultaneously measuring a brainwave signal of a user with a sensor, wherein the brainwave signal indicates an attention level of the user, wherein measuring a brainwave signal comprises assigning a numeric value to the brainwave signal indicating the attention level of the user;

indexing the media file by correlating the measured brainwave signal to the media file; and

displaying one or more segments of the selected media file, each segment corresponding to correlated brainwave signal having a numeric value that exceeds a threshold value indicating a particular attention level.

2. The method according to claim 1 , wherein the media file comprises an audio file, a video file, or a multimedia file.

3. The method according to claim 1 , wherein indexing the played media file comprises correlating a time of the media file to the measured brainwave signal associated with that time.

4. The method according to claim 1 , further comprising displaying on a media device the selected media file and a correlated brainwave signal.

5. A system for indexing media files, the system comprising:

a media device configured to play a media file;

a sensor configured to simultaneously measure brainwave signals of a user, wherein the brainwave signal indicates an attention level of the user, the sensor further configured to assign a numeric value to the brainwave signal indicating the attention level of the user;

a processor coupled to the sensor and configured to receive the measured brainwave signals and index the media file by correlating the measured brainwave signal to the media file; and

wherein the media device is further configured to display one or more segments of an indexed media file, each segment corresponding to correlated brainwave signal having a numeric value that exceeds a threshold value indicating a particular attention level.

6. The system according to claim 5 , wherein the media file comprises an audio file, a video file, or a multimedia file.

7. The system according to claim 5 , wherein the sensor comprises a dry active electrode sensor or a wet electrode sensor integral with a headgear worn by the user.

8. The system according to claim 5 , wherein the processor is configured to correlate a time of the media file to the measured brainwave signal.

9. The system according to claim 5 , wherein the media device is further configured to display an indexed media file and a brainwave signals.

10. A non-transitory computer-readable medium comprising computer-executable instructions, the instructions configured to, when executed by a processor:

receive a selected media file;

play the selected media file on a media device and simultaneously measure a brainwave signal of a user with a sensor, wherein the brainwave signal indicates an attention level of the user, wherein measuring a brainwave signal comprises assigning a numeric value to the brainwave signal indicating the attention level of the user;

index the media file by correlating the measured brainwave signal to the media file; and

display one or more segments of an indexed media file, each segment corresponding to correlated brainwave signal having a numeric value that exceeds a threshold value indicating a particular attention level.

11. The computer-readable medium according to claim 10 , wherein the software is embodied in a storage device coupled to a processor of a processing system.

12. The computer-readable medium according to claim 10 , wherein indexing the played media file comprises correlating a time of the media file to the measured brainwave signal.

13. The computer-readable medium according to claim 10 , the instructions are further configured to display an indexed media file and a brainwave signals.

14. The computer-readable medium according to claim 10 , wherein the media file comprises an audio file, a video file, or a multimedia file.
