Abstract

A sleep scoring device is provided for, including a contactless biometric sensor, a processor, memory, and a microphone. The sleep scoring device may detect a user's sleep state by reading signals from the contactless biometric sensor based on at least one of a detected change in heartrate, body movement, or respiration, and log the biometric information. The sleep scoring device may also generate a sleep score for a sleep session based on the latency of the sleep session, the number of detected waking events, the amount of REM sleep, the amount of deep sleep, or the number of times the snooze button was pressed during the sleep session.

First claim

What is claimed:

1. A sleep scoring device comprising:
a contactless biometric sensor for determining at least one of a heart rate, a respiratory rate, a presence of a user, or movement of the user;
a processor;
memory; and
a microphone;
wherein said processor is configured to, during a sleep session, detect the user's sleep state by reading signals from said contactless biometric sensor based on at least one of a detected change in heartrate, body movement, or respiration, log information in a sleep record, including biometric information relating to the quality of the user's sleep and environmental factors that may affect the quality of the user's sleep,
generate and display a numerical sleep score for said sleep session based on consistency of the logged information with corresponding information logged on previous days, and
generate a sleep consistency report based on the sleep record, the sleep consistency report illustrating comparative sleep data of the user over multiple days as graphical representations of sleep patterns of the user, each graphical representation being representative of sleep patterns of the user in a single sleep session.

2. The sleep scoring device of claim 1 , wherein said processor is further configured to detect sleep stages and to log a start time and a stop time of said sleep stages in said sleep record.

3. The sleep scoring device of claim 2 , wherein said sleep stages comprise at least one of REM sleep, N-REM sleep, deep sleep, light sleep, stage 1 sleep, stage 2 sleep, stage 3 sleep, or stage 4 sleep.

4. The sleep scoring device of claim 3 , wherein said environmental factors comprise one or more of temperature, noise levels, air pressure, air pollution, or light levels.

5. The sleep scoring device of claim 4 , wherein said processor is further configured to record detected sounds when sounds are detected at or near a same time as a detected wake-up event of the user.

6. The sleep scoring device of claim 1 , wherein said processor is further configured to log one or more sleep start times and one or more sleep stop times.

7. The sleep scoring device of claim 6 , wherein said processor is further configured to detect the user's presence in a sleep space and to log a time the user entered the sleep space in said sleep record.

8. The sleep scoring device of claim 1 , wherein said processor is further configured to receive information regarding at least one of said environmental factors from an external database.

9. The sleep scoring device of claim 8 , wherein said external database comprises a weather database, a health database, a fitness database, or a calendar database.

10. The sleep scoring device of claim 1 , wherein said processor is further configured to generate the sleep score based on at least one of a detected duration of the sleep or the quality of the sleep.

11. The sleep scoring device of claim 10 , wherein the quality of the sleep is determined based on one or more of a detected latency of the sleep session, a number of detected waking events during the sleep session, an amount of REM sleep detected during the sleep session, an amount of deep sleep detected during the sleep session, or a number of times a snooze button was pressed during the sleep session.

12. The sleep scoring device of claim 1 , wherein said processor is further configured to solicit external sleep factors from the user.

13. The sleep scoring device of claim 1 , wherein said processor is further configured to analyze information in said sleep record and to identify potential corollaries between instances of sub-optimal sleep and said biometric information, said environmental factors, or external sleep factors.

14. The sleep scoring device of claim 1 , wherein said processor is further configured to generate the sleep score based on at least on a number of times a snooze button was pressed during the sleep session.

15. A method for monitoring and scoring sleep comprising:
receiving a plurality of biometric readings of a user from a contactless biometric sensor;
recording said plurality of biometric readings within a sleep record;
determining said user's sleep state based on said plurality of biometric readings;
logging said user's sleep state within said sleep record;
determining and displaying a numerical sleep score based, at least in part, on consistency of the logged information with corresponding information logged on previous days; and
generating a sleep consistency report based on the sleep record, the sleep consistency report illustrating comparative sleep data of the user over multiple days, the sleep consistency report including graphical representations of sleep patterns of the user for multiple respective days, each graphical representation being representative of sleep patterns of the user in a single sleep session.

16. The method for monitoring and scoring sleep of claim 15 , further comprising detecting said user's presence in a sleep space based on said plurality of biometric readings and recording the user's presence in said sleep record.

17. The method for monitoring and scoring sleep of claim 16 , further comprising detecting sleep stages based on said plurality of biometric readings and recording said sleep stages in said sleep record.

18. The method for monitoring and scoring sleep of claim 17 , wherein said sleep stages comprise at least one of REM sleep, N-REM sleep, deep sleep, light sleep, stage 1 sleep, stage 2 sleep, stage 3 sleep, or stage 4 sleep.

19. The method for monitoring and scoring sleep of claim 15 , further comprising:
receiving a plurality of environmental readings including at least one of a sound level, a light level, an air quality reading, or a temperature; and
recording said plurality of environmental readings in the sleep record.

20. The method for monitoring and scoring sleep of claim 19 , further comprising receiving external sleep factors and recording them in said sleep record.

21. The method for monitoring and scoring sleep of claim 20 , further comprising analyzing information in said sleep record and identifying potential corollaries between instances of sub-optimal sleep and said plurality of environmental readings, said plurality of biometric readings, or said external sleep factors.

22. A sleep monitoring and scoring system comprising:
a biometric sensor;
a microphone;
memory; and
a processor, coupled to the biometric sensor, the memory, and the microphone, the processor being configured to detect a user's sleep state during a sleep session by reading signals from said contactless biometric sensor based on at least one of a detected change in heartrate, body movement, or respiration, and wherein said processor is further configured to log information in a sleep record, including biometric information relating to the quality of a user's sleep and environmental factors that may affect the quality of a user's sleep, to generate and display a numerical sleep score for said sleep session based on consistency of the logged information with corresponding information logged on previous days, and to generate a sleep consistency report based on the sleep record, the sleep consistency report illustrating comparative sleep data of the user over multiple days, the sleep consistency report including graphical representations of sleep patterns of the user for multiple respective days, each graphical representation being representative of sleep patterns of the user in a single sleep session.
