Brain-wave aware sleep management

1. A system, comprising:

a port to receive brain activity data of a user;

a processor to detect a beginning time of a user nap based upon the brain activity data and to store the beginning time and time of day; and

a user interface to notify the user when a predetermined nap time has elapsed.

2. The system of claim 1 , the system further comprising a store.

3. The system of claim 1 , the processor further to generate a model of brain activity over a defined period of time.

4. The system of claim 3 , the user interface further to present the model of brain activity to the user.

5. The system of claim 3 , the processor to make recommendations to the user through the user interface based upon the model.

6. The system of claim 1 , the user interface to allow the user to select the predetermined nap time.

7. The system of claim 1 , the processor further to detect a user drowsiness level and to make a recommendation to the user.

8. The system of claim 7 , the recommendation further comprising one of either to take a nap or to perform an alerting activity to stay awake.

9. A method of monitoring a user somnolence level, comprising:

receiving brain activity data from a user;

determining a somnolence level from the brain activity data;

storing data including the somnolence level and time of day;

if the somnolence level is sleep, determining using a processor if a nap has progressed to a waking point; and

if the nap has progressed to a waking point, alerting the user.

10. The method of claim 9 , further comprising if the somnolence level is drowsy, providing a recommendation to the user to take a nap.

11. The method of claim 9 , further comprising using the data to generate a model of user somnolence behavior.

12. The method of claim 11 , further comprising providing the model to a user calendar to allow a user to plan activities using the model.

13. The method of claim 9 , receiving brain activity data from a user further comprising receiving the data as signals from a wireless electroencephalogram headset.

14. The method of claim 9 , wherein alerting the user comprises alerting the user when the user is in a light sleep stage.

15. An article of computer-readable media storing instructions that, when executed, cause the computer to:

receive brain activity data from a user;

determine a somnolence level from the brain activity data;

storing the somnolence level and time of day;

if the somnolence level is sleep, determine if a nap timer has elapsed; and

if the nap timer has elapsed, alert the user.

16. The article of claim 15 , the instructions further causing the computer to make a recommendation to the user to take a nap, if the somnolence level is drowsy.

17. The article of claim 15 , the instructions further causing the computer to present a user interface to allow the user to set the nap timer.
