Abstract

A method (50) of altering content provided to a user includes the steps of creating (60) a user profile based on past physiological measurements of the user, monitoring (74) at least one current physiological measurement of the user, and altering (82) the content provided to the user based on the user profile and the at least one current physiological measurement. The user profile can be created by recording a plurality of inferred or estimated emotional states (64) of the user which can include a time sequence of emotional states, stimulus contexts for such states, and a temporal relationship between the emotional state and the stimulus context. The content can be altered in response to the user profile and measured physiological state by altering at least one among an audio volume, a video sequence, a sound effect, a video effect, a difficulty level, a sequence of media presentation.

Claims

1. A method of altering content provided to a user, comprising the steps of:

creating a user profile based on past physiological measurements of the user;

monitoring at least one current physiological measurement of the user; and

altering the content provided to the user based on the user profile and the at least one current physiological measurement.

2. The method of claim 1, wherein the step of creating the user profile comprises the step of recording a plurality of inferred or estimated emotional states of the user.

3. The method of claim 1, wherein the step of creating the user profile comprises the step of recording at least one or more among a plurality of inferred or estimated emotional states of the user, a time sequence of emotional states, stimulus contexts, and a temporal relationship between the emotional state and the stimulus context.

4. The method of claim 1, wherein the step of creating the user profile comprises the step of recording environmental conditions selected among the group comprising lighting, loudness, humidity, weather, temperature, and location.

5. The method of claim 1, wherein the step of creating the user profile comprises the step of storing at least one among user id, age, gender, education, temperament, and past history with the same or similar stimulus class.

6. The method of claim 1, wherein the step of monitoring comprises the step of monitoring at least one among heart rate, pulse, blood oxygen levels, temperature, eye movements, body movements, breathing rates, audible vocalizations, skin conductivity, skin resistivity, Galvanic skin responses, audio level sensing, or force sensing.

7. The method of claim 1, wherein the step of altering the content comprises altering at least one among an audio volume, a video sequence, a sound effect, a video effect, a difficulty level, a sequence of media presentation in response to the user profile and the at least one current physiological measurement.

8. A method of altering content provided to a user, comprising the steps of:

retrieving a user profile based on past physiological measurements of the user;

monitoring at least one current physiological measurement of the user; and

altering the content provided to the user based on the user profile and the at least one current physiological measurement.

9. The method of claim 8, wherein the user profile contains at least one among a user preference, a user id, age, gender, education, temperament, and a past history with the same or similar stimulus class.

10. The method of claim 8, wherein the user profile comprises the step of recording at least one or more among a plurality of inferred or estimated emotional states of the user, a time sequence of emotional states, stimulus contexts, a temporal relationship between the emotional state and the stimulus context.

11. The method of claim 10, wherein the user profile further comprises recorded environmental conditions selected among the group comprising lighting, loudness, humidity, weather, temperature, and location.

12. The method of claim 8, wherein the step of monitoring comprises the step of monitoring at least one among heart rate, pulse, blood oxygen levels, temperature, eye movements, body movements, breathing rates, audible vocalizations, skin conductivity, skin resistivity, Galvanic skin responses, audio level sensing, or force sensing.

13. An electronic device, comprising:

a sensor for monitoring at least one current physiological measurement of a user;

a memory for storing a user profile containing information based on past physiological measurements of the user;

a presentation device for providing a presentation to the user; and

a processor coupled to the sensor and the presentation device, wherein the processor is programmed to alter the presentation based on the user profile and the at least one current physiological measurement of the user.

14. The electronic device of claim 13, wherein the user profile comprises at least one or more among a plurality of inferred or estimated emotional states of the user, a time sequence of emotional states, stimulus contexts, and a temporal relationship between the emotional state and the stimulus context.

15. The electronic device of claim 13, wherein the user profile further comprises recorded environmental conditions selected among the group comprising lighting, loudness, humidity, weather, temperature, and location.

16. The electronic device of claim 13, wherein the user profile comprises at least one among a user id, age, gender, education, temperament, and past history with the same or similar stimulus class.

17. The electronic device of claim 13, wherein the electronic device comprises at least one among a mobile phone, a smart phone, a PDA, a laptop computer, a desktop computer, an electronic gaming device, a gaming controller, a remote controller, a DVD player, an MP3 player, or a CD player.

18. The electronic device of claim 13, wherein the sensor for monitoring comprises at least one sensor for monitoring at least one among heart rate, pulse, blood oxygen levels, skin conductivity, skin resistivity, Galvanic skin responses, audio level sensing, location, or force sensing.

19. The electronic device of claim 13, wherein the presentation device comprises at least one among a display, an audio speaker, a vibrator, or other sensory output device.

20. The electronic device of claim 13, wherein the electronic device further comprises a receiver and a transmitter coupled to the processor.
