Ear-worn electronic device for conducting and monitoring mental exercises

1. A method implemented by an ear-worn electronic device configured to be worn by a wearer and comprising a right ear device and a left ear device, the method comprising:

producing, by the ear-worn electronic device, a three-dimensional virtual sound environment comprising relaxing sounds;

generating, by the ear-worn electronic device, verbal instructions within the three-dimensional virtual sound environment that guide the wearer through a predetermined mental exercise that promotes wearer relaxation;

sensing, during the predetermined mental exercise, at least one physiologic parameter from the wearer by the ear-worn electronic device;

sensing, during the predetermined mental exercise, movement of the wearer by the ear-worn electronic device; and

generating, by the ear-worn electronic device, verbal commentary that assesses wearer compliance with the predetermined mental exercise in response to one or both of the at least one physiologic parameter and the sensed movement of the wearer.

2. The method of claim 1 , comprising evaluating an effectiveness of the mental exercise in response to the at least one physiologic parameter.

3. The method of claim 1 , wherein the at least one physiologic parameter comprises a parameter indicative of the wearer's mental state.

4. The method of claim 1 , wherein the at least one physiologic parameter comprises an electroencephalogram (EEG) signal and one or both of a parameter indicative of heart rate and a parameter indicative of breathing.

5. The method of claim 1 , wherein:

the at least one physiologic parameter comprises an electroencephalogram (EEG) signal and a parameter indicative of breathing; and

the method further comprises using an association between the EEG signal and the breathing parameter to determine the wearer's focus on breathing during the mental exercise.

6. The method of claim 1 , further comprising:

detecting noncompliance with the predetermined mental exercise by the wearer in response to a deviation in one or both of the sensed movement of the wearer and the at least one physiologic parameter;

wherein generating the verbal commentary comprises generating verbal commentary that encourages wearer compliance with the predetermined mental exercise.

7. The method of claim 6 , wherein the deviation is indicative of wearer distraction or an increase in wearer stress.

8. The method of claim 1 , further comprising modifying the verbal instructions that guide the wearer through the predetermined mental exercise in response to a level of wearer expertise in performing the predetermined mental exercise.

9. The method of claim 1 , further comprising:

classifying a sound of interest received by the ear-worn electronic device during the mental exercise; and

performing one or both of:

generating verbal commentary suggesting that the wearer either ignore or consider the sound of interest in response to the classification of the sound of interest; and

selectively implementing noise cancellation to either cancel or pass the sound of interest based on the classification of the sound of interest.

10. The method of claim 1 , further comprising maintaining realism of the three-dimensional virtual sound environment in response to sensing movement of the wearer during performance of the predetermined mental exercise.

11. The method of claim 1 , comprising:

collecting data generated during the predetermined mental exercise to produce a user profile for the wearer;

performing the method by a plurality of wearers of the ear-worn electronic devices;

collecting data generated by the ear-worn electronic devices of the plurality of wearers to produce a population profile; and

updating the wearer's user profile using data from the population profile.

12. An ear-worn electronic device configured to be worn by a wearer and comprising:

a right ear device comprising a first processor;

a left ear device comprising a second processor communicatively coupled to the first processor;

a physiologic sensor module comprising one or more physiologic sensors configured to sense at least one physiologic parameter from the wearer;

a motion sensor module comprising one or more sensors configured to sense movement of the wearer;

the first and second processors coupled to the physiologic and motion sensor modules; and

the first and second processors configured to produce a three-dimensional virtual sound environment comprising relaxing sounds, generate verbal instructions within the three-dimensional virtual sound environment that guide the wearer through a predetermined mental exercise that promotes wearer relaxation, and generate verbal commentary that assesses wearer compliance with the predetermined mental exercise in response to one or both of the sensed movement and the at least one physiologic parameter.

13. The device of claim 12 , wherein at least one of the first and second processors is configured to evaluate an effectiveness of the mental exercise in response to the at least one physiologic parameter.

14. The device of claim 12 , wherein the at least one physiologic parameter comprises a parameter indicative of the wearer's mental state.

15. The device of claim 12 , wherein the at least one physiologic parameter comprises an electroencephalogram (EEG) signal and one or both of a parameter indicative of heart rate and a parameter indicative of breathing.

16. The device of claim 12 , wherein:

the at least one physiologic parameter comprises an electroencephalogram (EEG) signal and a parameter indicative of breathing; and

at least one of the first and second processors is configured to use an association between the EEG signal and the breathing parameter to determine the wearer's focus on breathing during the mental exercise.

17. The device of claim 12 , wherein:

at least one of the first and second processors is configured to detect noncompliance with the predetermined mental exercise by the wearer in response to detecting a deviation in one or both of the sensed movement of the wearer and the at least one physiologic parameter; and

the first and second processors are configured to generate verbal commentary that encourages wearer compliance with the predetermined mental exercise.

18. The device of claim 17 , wherein the deviation is indicative of wearer distraction or an increase in wearer stress.

19. The device of claim 12 , wherein the first and second processors are configured to modify the verbal instructions that guide the wearer through the predetermined mental exercise in response to a level of wearer expertise in performing the predetermined mental exercise.

20. The device of claim 12 , wherein:

at least one of the first and second processors is configured to classify a sound of interest received by the ear-worn electronic device during the mental exercise; and

the first and second processors are configured to:

generate verbal commentary suggesting that the wearer either ignore or consider the sound of interest in response to the classification of the sound of interest; and

selectively implement noise cancellation to either cancel or pass the sound of interest based on the classification of the sound of interest.

21. The device of claim 12 , wherein the first and second processors are configured to maintain realism of the three-dimensional virtual sound environment in response to sensing movement of the wearer during performance of the predetermined mental exercise.

22. The device of claim 12 , wherein:

at least one of the first and second processors is configured to collect data generated during the predetermined mental exercise to produce a user profile for the wearer and to communicate with a remote server via a gateway device; and
