Abstract
The present disclosure provides computer-implemented methods, systems, and devices for improved skin temperature monitoring. Accurate estimates of skin and ambient temperature are generated based on determinations and comparisons of skin and internal device temperature sensor measurements contained on or within example devices. The estimates of skin and ambient temperature measurements facilitate monitoring skin and core temperature changes, detecting physiological events of a wearer of example devices, and determining when skin temperature changes are environmentally or physiologically induced.
Claims20
A computer-implemented method of skin temperature monitoring, the method comprising:
- determining, by a computing system comprising one or more processors, an internal device temperature of a wearable device worn by a user based on first sensor data received from a first sensor included on or contained within the wearable device;
- determining, by the computing system, a first estimate of a skin temperature of the user based on second sensor data received from a second sensor included on or contained within the wearable device;
- determining, by the computing system, based at least in part on inputting the first estimate of the skin temperature and the internal device temperature into a machine-learned model, an estimated ambient air temperature;
- and
- generating, by the computing system, based on refining the first estimate of the skin temperature based at least in part on the estimated ambient air temperature, a second estimate of the skin temperature.
A wearable device, comprising:
- a device housing;
- one or more processors included within the device housing;
- a display;
- an ambient light sensor;
- a thermally conductive baseplate located on an opposite side of the device from the display, wherein the thermally conductive baseplate is configured to be in direct thermal contact with skin of a user;
- a band configured to be secured to an arm of the user, wherein a plurality of temperature sensors are incorporated into the band, wherein the plurality of temperature sensors form a first sensor, and wherein the first sensor is included on or within the device housing and is configured to produce skin temperature sensor data;
- a second sensor that is included on or contained within the device housing and is configured to produce internal device temperature sensor data,
- wherein the first sensor, or the second sensor further comprise at least one of a location sensor, a geo-sensor, a weather sensor, a motion sensor, an altitude sensor, an altimeter temperature sensor, the ambient light sensor, or a heart rate sensor included on or contained within the wearable device;
- and non-transitory computer-readable memory included within the device housing and storing instructions that, when executed by the one or more processors, cause the wearable device to perform operations, the operations comprising:
- determining an internal device temperature of the wearable device based on first sensor data received from the first sensor;
- determining a first estimate of a skin temperature of the user based on second sensor data received from the second sensor;
- determining, based at least in part on inputting the first estimate of the skin temperature and the internal device temperature into a machine-learned model, an estimated ambient air temperature;
- and
- generating, based on refining the first estimate of the skin temperature based at least in part on the estimated ambient air temperature, a second estimate of the skin temperature.
