Abstract
Embodiments of a framework are disclosed for stair escalation to capture high resolution heart rate data that can be used to develop cardio fitness metrics related to stair climbing.
Claims2
A method comprising:
- obtaining a window of climbing probability samples, the climbing probability samples indicating the probability that a user of the wearable device is climbing stairs;
- computing a stair metric based on the window of climbing probability samples;
- validating the stair metric;
- obtaining a window of vertical speed samples, the vertical speed samples indicating the vertical speed of the wearable device;
- determining an ascending or descending condition based on the window of vertical speed samples;
- and
- initiating escalation of a heart rate sensor based on the validated stair metric and the ascending or descending condition.
4 more elements
A system comprising:
- at least one processor;
- memory storing instructions, that when executed by the at least one processor, cause the at least one processor to perform operations comprising:
- obtaining a window of climbing probability samples, the climbing probability samples indicating the probability that a user of the wearable device is climbing stairs;
- computing a stair metric based on the window of climbing probability samples;
- validating the stair metric;
- obtaining a window of vertical speed samples, the vertical speed samples indicating the vertical speed of the wearable device;
- determining an ascending or descending condition based on the window of vertical speed samples;
- and
- initiating escalation of a heart rate sensor based on the validated stair metric and the ascending or descending condition.
