Abstract

Claims (53)

1. A method of assessing sleep quality of a user at an electronic device having one or more processors and a non-transitory computer readable storage medium, the method comprising:

receiving one or more signals indicating an attempt by the user to fall asleep;

receiving physiological information associated with the user including at least one sleeping heart rate, the physiological information generated by one or more physiological sensors;

determining respective values for one or more sleep quality metrics based at least in part on the physiological information and at least one wakeful resting heart rate of the user; and

determining a unified score for sleep quality of the user, based at least in part on the respective values of the one or more sleep quality metrics.

2. The method of claim 1 wherein the at least one wakeful resting heart rate includes a representative value of one or more of the user's heart rate values during a period of relative inactivity while the user is awake.

3. The method of claim 1 wherein the one or more sleep quality metrics includes a first set of sleep quality metrics associated with sleep quality of a plurality of users, and a second set of sleep quality metrics associated with historical sleep quality of the user.

4. The method of claim 1 , wherein determining the unified score for sleep quality includes:

determining a respective metric-score for each of the one or more sleep quality metrics; and

applying a respective weighting for each of the one or more sleep quality metrics.

5. The method of claim 1 further comprising determining the at least one wakeful resting heart rate of the user before receiving one or more signals indicating an attempt by the user to fall asleep.

6. The method of claim 1 wherein the physiological information associated with the user includes one or more sets of values associated with: movement of the user, total sleep duration, total deep sleep duration, duration of wake time after sleep onset (WASO), total rapid-eye-movement (REM) sleep duration, total light sleep duration, breathing patterns of the user, breathing disturbances of the user and temperature of the user.

7. The method of claim 1 further comprising:

receiving sleep quality feedback information from the user; and

determining the unified score for sleep quality of the user based at least in part on the sleep quality feedback information.

8. The method of claim 1 , wherein determining respective values for the one or more sleep quality metrics includes comparing the at least one sleeping heart rate of the user and the at least one wakeful resting heart rate of the user.

9. The method of claim 1 further comprising:

receiving one or more signals indicating an onset of sleep by the user; and

determining a duration of time from the attempt to fall asleep to the onset of sleep.

10. The method of claim 9 further comprising:

receiving one or more signals indicating that the user is awake after the detected onset of sleep; and

determining the respective values for one or more sleep quality metrics, in response to receiving one or more signals indicating that the user is awake.

11. An electronic device, comprising:

one or more physiological sensors;

one or more processors;

a non-transitory computer readable storage medium; and

control circuitry configured to:

detect an attempt by the user to fall asleep;

collect physiological information associated with the user, including at least one sleeping heart rate;

determine respective values for one or more sleep quality metrics, based at least in part on the collected physiological information and at least one wakeful resting heart rate of the user; and

determine a unified score for sleep quality of the user, based at least in part on the respective values of the one or more sleep quality metrics.

12. The electronic device of claim 11 , wherein the control circuitry is further configured to present a representation of the unified score to the user.

13. The electronic device of claim 11 , wherein the one or more sleep quality metrics includes a first set of sleep quality metrics associated with sleep quality of a plurality of users, and a second set of sleep quality metrics associated with historical sleep quality of the user.

14. The electronic device of claim 11 , wherein the control circuitry being configured to determine the unified score for sleep quality includes being configured to:

determine a respective metric-score for each of the one or more sleep quality metrics; and

apply a respective weighting for each of the one or more sleep quality metrics.

15. The electronic device of claim 11 , wherein the control circuitry is further configured to determine the at least one wakeful resting heart rate of the user before detecting an attempt by the user to fall asleep.

16. The electronic device of claim 11 , wherein the physiological information associated with the user includes one or more sets of values associated with: movement of the user, total sleep duration, total deep sleep duration, duration of wake time after sleep onset (WASO), total rapid-eye-movement (REM) sleep duration, total light sleep duration, breathing patterns of the user, breathing disturbances of the user and temperature of the user.

17. The electronic device of claim 11 , wherein the control circuitry is further configured to:

collect sleep quality feedback information from the user; and

determine the unified score for sleep quality of the user based at least in part on the collected sleep quality feedback information.

18. The electronic device of claim 11 , wherein the control circuit being configured to determine respective values for the one or more sleep quality metrics includes being configured to compare the at least one sleeping heart rate of the user and the at least one wakeful resting heart rate of the user.

19. The electronic device of claim 11 , wherein the control circuitry is further configured to:

detect an onset of sleep by the user; and

determine a duration of time from the attempt to fall asleep to the onset of sleep.

20. The electronic device of claim 19 , wherein the control circuitry is further configured to:

detect that the user is awake after the detected onset of sleep; and

determine the respective values for one or more sleep quality metrics, in response to detecting that the user is awake.

21. A non-transitory computer readable storage medium storing one or more programs, the one or more programs comprising instructions, which when executed by an electronic device with one or more physiological sensors, cause the device to:

detect an attempt by the user to fall asleep;

collect physiological information associated with the user, including at least one sleeping heart rate;

determine respective values for one or more sleep quality metrics, based at least in part on the collected physiological information and at least one wakeful resting heart rate of the user; and

determine a unified score for sleep quality of the user, based at least in part on the respective values of the one or more sleep quality metrics.
