Abstract

Claims (43)

1 . A system for supplemental sleep detection, comprising:

a wearable device comprising one or more sensors configured to acquire physiological data from a user;

a user device communicatively coupled with the wearable device; and

one or more processors communicatively coupled with the user device, the wearable device, or both, wherein the one or more processors are configured to:

receive, from the wearable device, physiological data acquired from the user via the wearable device;

detect a primary sleep period for the user during a sleep day based at least in part on a first subset of the physiological data, wherein the sleep day ends at a determined cut-off time of day;

generate a set of one or more scores associated with the sleep day based at least in part on the primary sleep period;

detect a supplemental sleep period based at least in part on a second subset of the physiological data;

identify a time of day that the supplemental sleep period occurred;

update the set of one or more scores associated with the sleep day to generate an updated set of one or more scores based at least in part on the supplemental sleep period and based at least in part on the time of day associated with the supplemental sleep period occurring before the determined cut-off time of day;

generate one or more signals to cause a graphical user interface (GUI) of the user device associated with the wearable device to display the updated set of one or more scores after the supplemental sleep period and an indication of supplemental sleep period; and

receive, via the user device and in response to the indication of the supplemental sleep period, a confirmation of the supplemental sleep period.

2 . The system of claim 1 , wherein the determined cut-off time of day is based at least in part on a time of day that the user typically begins a primary sleep period each calendar day.

3 . The system of claim 1 , wherein the determined cut-off time of day is based at least in part on a sleeping pattern of the user.

4 . The system of claim 1 , wherein the determined cut-off time of day is associated with the user beginning a second primary sleep period associated with a second sleep day.

5 . The system of claim 1 , wherein the sleep day aligns with a calendar day such that determined cut-off time of day is midnight.

6 . The system of claim 1 , wherein the one or more processors are further configured to:

receive, via the user device, a user input indicating the determined cut-off time of day.

7 . The system of claim 1 , wherein the supplemental sleep period is detected based at least in part on a first duration of the supplemental sleep period being less than a second duration of the primary sleep period.

8 . The system of claim 1 , wherein the set of one or more scores comprise a first score that is calculated using a set of factors, wherein, to update the set of one or more scores, the one or more processors are configured to:

update at least a subset of factors of the set of factors.

9 . The system of claim 1 , wherein the supplemental sleep period is detected based at least in part on a first duration of the supplemental sleep period being within a threshold range of durations.

10 . The system of claim 1 , wherein the one or more processors are further configured to:

generate a second signal to cause the GUI to display one or more insights associated with the user based at least in part on the primary sleep period and the supplemental sleep period, wherein the one or more insights comprise a suggestion associated with one or more characteristics of future supplemental sleep periods.

11 . A method for supplemental sleep detection, comprising:

receiving, from a wearable device comprising one or more sensors, physiological data acquired from a user via the wearable device;

detecting a primary sleep period for the user during a sleep day based at least in part on a first subset of the physiological data, wherein the sleep day ends at a determined cut-off time of day;

generating a set of one or more scores associated with the sleep day based at least in part on the primary sleep period;

detecting a supplemental sleep period based at least in part on a second subset of the physiological data;

identifying a time of day that the supplemental sleep period occurred;

updating the set of one or more scores associated with the sleep day to generate an updated set of one or more scores based at least in part on the supplemental sleep period and based at least in part on the time of day associated with the supplemental sleep period occurring before the determined cut-off time of day;

generating one or more signals to cause a graphical user interface (GUI) of a user device associated with the wearable device to display the updated set of one or more scores after the supplemental sleep period and an indication of supplemental sleep period; and

receiving, via the user device and in response to the indication of the supplemental sleep period, a confirmation of the supplemental sleep period.

12 . The method of claim 11 , wherein the determined cut-off time of day is based at least in part on a time of day in which the user typically begins a primary sleep period each calendar day.

13 . The method of claim 11 , wherein the determined cut-off time of day is based at least in part on a sleeping pattern of the user.

14 . The method of claim 11 , wherein the determined cut-off time of day is associated with the user beginning a second primary sleep period associated with a second sleep day.

15 . The method of claim 11 , further comprising:

receiving, via the user device, a user input indicating the determined cut-off time of day.

16 . The method of claim 11 , wherein the supplemental sleep period is detected based at least in part on a first duration of the supplemental sleep period being less than a second duration of the primary sleep period.

17 . The method of claim 16 , wherein the set of one or more scores comprise a first score that is calculated using a set of factors, and wherein updating the set of one or more scores comprises:

updating at least a subset of factors of the set of factors.

18 . The method of claim 11 , further comprising:

generating a second signal to cause the GUI to display one or more insights associated with the user based at least in part on the primary sleep period and the supplemental sleep period, wherein the one or more insights comprise a suggestion associated with one or more characteristics of future supplemental sleep periods.
