Determining resting heart rate using wearable device
[+] Show Details

US10932715

1. A computer-implemented method for determining a minimum heart rate, comprising: (6) (2)

initializing a current minimum heart rate result; and

for each of a plurality of sampling periods when a wearer of a wearable device is asleep: obtaining via the wearable device a sequence of heart rate samples for the wearer;

assessing whether a threshold percentage of the heart rate samples is usable; and

if at least the threshold percentage of the heart rate samples is assessed to be usable: aggregating the heart rate samples assessed to be usable, wherein aggregating the heart rate samples comprises determining a value that is representative of the heart rate samples; and

if the aggregated heart rate samples are smaller than the current minimum heart rate result, blending the aggregated heart rate samples into the current minimum heart rate result.

2. The method of claim 1, wherein the assessing, aggregating, and blending are performed on the wearable device. (0)

3. The method of claim 1, wherein the assessing, aggregating, and blending are performed on a computer system distinct from the wearable device. (0)

4. The method of claim 1, wherein: (0) (3)

5. The method of claim 1, further comprising determining that the wearer of the wearable device is asleep based upon explicit input from the wearer. (0)

6. The method of claim 1, further comprising inferring that the wearer of the wearable device is asleep. (0)

7. The method of claim 1, wherein aggregating the heart rate samples comprises determining at least one of a mean, a median, a mode, or a minimum of the heart rate samples. (0)

8. A computer system for determining a minimum heart rate, comprising: (6) (2)

one or more processors; and

memory comprising instructions that are executable by the one or more processors to: initialize a current minimum heart rate result; and

for each of a plurality of sampling periods when a wearer of a wearable device is asleep: obtain via the wearable device a sequence of heart rate samples for the wearer;

assess whether a threshold percentage of the heart rate samples is usable; and

if at least the threshold percentage of the heart rate samples is assessed to be usable: aggregate the heart rate samples assessed to be usable, wherein aggregating the heart rate samples comprises determining a value that is representative of the heart rate samples; and

if the aggregated heart rate samples are smaller than the current minimum heart rate result, blend the aggregated heart rate samples into the current minimum heart rate result.

9. The computer system of claim 8, wherein the computer system comprises the wearable device. (0)

10. The computer system of claim 8, wherein the computer system is distinct from the wearable device. (0)

11. The computer system of claim 8, wherein: (0) (3)

12. The computer system of claim 8, wherein the instructions are additionally executable by the one or more processors to determine that the wearer of the wearable device is asleep based upon explicit input from the wearer. (0)

13. The computer system of claim 8, wherein the instructions are additionally executable by the one or more processors to infer that the wearer of the wearable device is asleep. (0)

14. The computer system of claim 8, wherein the instructions that are executable by the one or more processors to aggregate the heart rate samples comprise instructions that are executable by the one or more processors to determine at least one of a mean, a median, a mode, or a minimum of the heart rate samples. (0)

15. A computer-readable medium having computer-executable instructions stored thereon that, when executed, cause one or more processors to: (5) (2)

initialize a current minimum heart rate result; and

for each of a plurality of sampling periods when a wearer of a wearable device is asleep: obtain via the wearable device a sequence of heart rate samples for the wearer;

assess whether a threshold percentage of the heart rate samples is usable; and

if the aggregated heart rate samples are smaller than the current minimum heart rate result, blend the aggregated heart rate samples into the current minimum heart rate result.

16. The computer-readable medium of claim 15, wherein the wearable device assesses whether the threshold percentage of the heart rate samples is usable, aggregates the heart rate samples assessed to be usable, and blends the aggregated heart rate samples into the current minimum heart rate result. (0)

17. The computer-readable medium of claim 15, wherein a computer system distinct from the wearable device assesses whether the threshold percentage of the heart rate samples is usable, aggregates the heart rate samples assessed to be usable, and blends the aggregated heart rate samples into the current minimum heart rate result. (0)

18. The computer-readable medium of claim 15, wherein: (0) (3)

19. The computer-readable medium of claim 15, wherein the computer-executable instructions additionally cause the one or more processors to determine that the wearer of the wearable device is asleep based upon explicit input from the wearer. (0)

20. The computer-readable medium of claim 15, wherein the computer-executable instructions additionally cause the one or more processors to infer that the wearer of the wearable device is asleep. (0)
