Abstract
A wearable device includes: a base to be worn on a head of a user; a first sensor that is provided to the base to be at a distance from a surface of the user's head and measures a first signal relating to a temperature of the surface of the user's head; an estimation circuit that estimates a body temperature of the user based on the first signal; and a display that presents the body temperature of the user estimated by the estimation circuit.
Claims15
A wearable device comprising:
- a base configured to be worn by a measurement subject;
- a first sensor on the base and configured to measure a first signal corresponding to a temperature of a surface of the measurement subject;
- an estimation circuit configured to estimate a body temperature of the measurement subject based on the first signal;
- a presentation device configured to present the body temperature of the measurement subject estimated by the estimation circuit;
- and
- a second sensor on the base and configured to measure a second signal indicating an intensity of ambient light at a position where the first signal is measured, wherein the estimation circuit is configured to correct the first signal based on the second signal and estimate the body temperature of the measurement subject based on the first signal that has been corrected based on the second signal.
