Abstract

Methods, systems, and devices for wearing detection are described. A user device may determine a condition to trigger an oxygen saturation measurement, or a measure of blood oxygen saturation (SpO2), for a user of a wearable device. The condition may be based on a physical state of the wearable device, a physiological state of the user, or both. In some examples, the user device may determine the condition based on one or more relationships between sensor data from the wearable device, application data, physiological data from the wearable device, or any combination thereof. The user device may receive a measure of oxygen saturation of the user from the wearable device. The user device may cause a graphical user interface (GUI) of the user device to display an indication of the measure of the oxygen saturation for the user.

First claim

What is claimed is:

1 . A method for performing oxygen saturation measurements from a wearable device, comprising:
determining a condition to trigger an oxygen saturation measurement for a user associated with the wearable device, wherein the condition corresponds to a physical state of the wearable device, a physiological state of the user, or both, and wherein the condition is determined based at least in part on one or more relationships between sensor data from the wearable device, application data, physiological data from the wearable device, or any combination thereof; receiving a measure of oxygen saturation associated with the user from the wearable device based at least in part on the condition; and causing a graphical user interface of a user device to display an indication of the measure of the oxygen saturation for the user.

2 . The method of claim 1 , further comprising:
selecting the condition to trigger the oxygen saturation measurement for the user associated with the wearable device based at least in part on a learning model, wherein the learning model comprises a mapping between a set of previous oxygen saturation measurements associated with the user, a respective oxygen saturation measurement accuracy associated with each of one or more previous oxygen saturation measurements of the set of previous oxygen saturation measurements, and a set of conditions associated with the set of previous oxygen saturation measurements.

3 . The method of claim 1 , further comprising:
transmitting a control signal to the wearable device to perform the oxygen saturation measurement for the user associated with the wearable device in accordance with an oxygen saturation measurement cycle based at least in part on the condition, wherein receiving the measure of the oxygen saturation associated with the user from the wearable device is based at least in part on the transmitted control signal to the wearable device to perform the oxygen saturation measurement.

4 . The method of claim 3 , further comprising:
selecting the oxygen saturation measurement cycle from a set of oxygen saturation measurement cycles based at least in part on a learning model, the learning model comprising a mapping between one or more conditions of a set of conditions and one or more oxygen saturation measurement cycles of the set of oxygen saturation measurement cycles, wherein transmitting the control signal to the wearable device to perform the oxygen saturation measurement is based at least in part on the selected oxygen saturation measurement cycle.

5 . The method of claim 3 , further comprising:
adjusting the oxygen saturation measurement cycle from a default oxygen saturation measurement cycle based at least in part on the condition.

6 . The method of claim 1 , further comprising:
receiving the sensor data from the wearable device associated with the user, wherein the sensor data indicates a position value associated with the wearable device relative to an anatomical feature associated with the user, the anatomical feature comprising a finger of the user, the position value being indicative of a physical locality of the wearable device on the anatomical feature associated with the user and corresponding to the physical state of the wearable device, wherein determining the condition comprises:
determining that the position value associated with the wearable device relative to the anatomical feature associated with the user satisfies a threshold position value for a threshold duration.

7 . The method of claim 1 , further comprising:
receiving the sensor data from the wearable device associated with the user, wherein the sensor data indicates an orientation value associated with the wearable device relative to an anatomical feature associated with the user, the anatomical feature comprising a finger of the user, the orientation value corresponding to the physical state of the wearable device, wherein determining the condition comprises:
determining that the orientation value associated with the wearable device relative to the anatomical feature associated with the user satisfies a threshold orientation value for a threshold duration.

8 . The method of claim 1 , further comprising:
receiving the sensor data from the wearable device associated with the user, wherein the sensor data indicates a pressure value between the wearable device and an anatomical feature associated with the user, the anatomical feature comprising a finger of the user, the pressure value being indicative of a force of the wearable device on the anatomical feature associated with the user and corresponding to the physical state of the wearable device, wherein determining the condition comprises:
determining that the pressure value between the wearable device and the anatomical feature associated with the user satisfies a threshold pressure value for a threshold duration.

9 . The method of claim 1 , further comprising:
receiving the sensor data from the user device associated with the user, wherein the sensor data indicates at least one sound characteristic associated with the user, wherein determining the condition comprises:
determining that the at least one sound characteristic associated with the user satisfies a threshold value.

10 . The method of claim 1 , further comprising:
receiving the application data, from the user device associated with the user, via one or more applications executable on the user device, the one or more applications executable on the user device comprising a lifestyle application, a social media application, a utility application, an information outlet application, or any combination thereof, and the application data is indicative of an activity the user is engaged in or a location of the user, or any combination thereof, wherein determining the condition comprises:
determining the activity the user is engaged in or the location of the user, or any combination thereof.

11 . The method of claim 1 , further comprising:
receiving the physiological data associated with the user from the wearable device, wherein determining the condition comprises:
determining that one or more physiological parameters of the received physiological data satisfies a threshold.

12 . The method of claim 11 , wherein at least one physiological parameter of the physiological data comprises heart rate data associated with the user, the heart rate data corresponding to the physiological state of the user, the method further comprising:
detecting an abnormal heart rate associated with the user based at least in part on the heart rate data, wherein the abnormal heart rate corresponds to a heart rate associated with the user different from a range of heart rate values associated with the user, wherein determining the condition comprises:
detecting the abnormal heart rate associated with the user.
