Summary: | An electronic device is provided. The electronic device includes a lighting-emitting diode (LED) module configured to emit light of a first polarization direction, a first photodiode configured to receive the light emitted from the LED module through a first polarizer having the first polarization direction, a second photodiode configured to receive the light emitted from the LED module through a second polarizer having a second polarization direction perpendicular to the first polarization direction, and a processor configured to determine wearing information of the electronic device based on luminous intensity of light sensed from each of the first photodiode and the second photodiode. |
