Abstract

The disclosure provides BMDs that have multiple device modes depending on operational conditions of the devices, e.g., motion intensity, device placement, and/or activity type. The device modes are associated with various data processing algorithms. In some embodiments, the BMD is implemented as a wrist-worn or arm-worn device. In some embodiments, methods for tracking physiological metrics using the BMDs are provided. In some embodiments, the process or the BMD applies a time domain analysis on data provided by a sensor of the BMD when the data has a high signal (e.g., high signal-to-noise ratio), and applies a frequency domain analysis on the data when the data has a low signal, which contributes to improved accuracy and speed of biometric data.

Claims21

Dependent claims

A biometric monitoring device comprising:

one or more motion sensors providing motion data;
a display device configured to present step count metrics;
and
one or more processors configured to:
operate the one or more motion sensors when the biometric monitoring device is in motion;
control the one or more motion sensors to generate a set of motion data indicative of movements of a user;
apply a frequency domain analysis to the set of motion data to obtain a first measure of a periodic component of the set of motion data;
apply a time domain analysis to the set of motion data to obtain a second measure of the periodic component of the set of motion data;
determine that a signal power of the set of motion data is lower than a threshold;
select, based on determining that the signal power is lower than the threshold, the first measure of the periodic component over the second measure of the periodic component;
update a step count metric of the user using the first measure of the periodic component;
and
control the display device of the biometric monitoring device to display the updated step count metric.
