Abstract
A wearable device, a charger, and a method for estimating absorbance of the wearable device are provided. The wearable device includes a spectroscope configured to emit a first light to a reference material of a charger, measure an intensity of the first light reflected from the reference material, emit a second light to a skin of a user, and measure an intensity of the second light reflected from the skin of the user; and a processor configured to determine absorbance of the skin of the user based on the intensity of the first light and the intensity of the second light.
Claims23
A wearable device comprising:
- a spectroscope configured to emit first light to a reference material of a charger, measure an intensity of the first light reflected from the reference material, emit second light to a skin of a user, and measure an intensity of the second light reflected from the skin of the user;
- and
- a processor configured to determine absorbance of the skin of the user based on the intensity of the first light and the intensity of the second light.
A charger of a wearable device which comprises a spectroscope, the charger comprising:
- a reference material arranged or coated on a side of the charger facing a light emitting side of the wearable device when the wearable device is installed on the charger.
A method for operating a wearable device, the method comprising:
- emitting first light to a reference material of a charger;
- measuring an intensity of the first light reflected from the reference material;
- emitting second light to a skin of a user;
- measuring an intensity of the second reflected from the skin of the user;
- and
- determining absorbance of the skin of the user based on the intensity of the first light and the intensity of the second light.
A wearable device comprising:
- a storage configured to store a reference reflective intensity;
- a light emitter configured to emit a light to a user of the wearable device;
- a spectroscope configured to receive the light reflected from the user and measure an intensity of the light;
- and
- a processor configured to determine absorbance of the user based on a comparison between the reference reflective intensity and the intensity of the light measured by the spectroscope.
