1. A wearable device comprising:
a display portion comprising:
a plurality of pixels each comprising:
a first light-emitting device configured to emit light having a first wavelength;
a first light-receiving device configured to convert visible light into an electric signal;
a second light-receiving device configured to convert infrared light into an electric signal; and
a pixel circuit configured to control light emission of the first light-emitting device;
a driver circuit configured to control the pixel circuit; and
an arithmetic circuit configured to perform arithmetic processing in an artificial neural network,
wherein the plurality of pixels is configured:
to capture an image of an user's eye and the surrounding of the eye;
to produce a plurality of currents by the first light-receiving device and the second light-receiving device of each of the plurality of pixels when the image is captured; and
to output the plurality of currents to the arithmetic circuit, and
wherein the arithmetic circuit is configured to infer a body temperature of the user on the basis of a first data corresponding to the plurality of currents.
