More Information
Summary:An electronic device is provided. The electronic device may comprise: an LED module which emits light in a first polarization direction; a first photodiode which receives light emitted from the LED module through a first polarization plate having the first polarization direction; a second photodiode which receives light emitted from the LED module through a second polarization plate having a second polarization direction perpendicular to the first polarization direction; and a processor which determines wearing information about the electronic device on the basis of luminous intensity of light sensed with respect to each of the first photodiode and the second photodiode. L'invention concerne un dispositif électronique. Le dispositif électronique peut comporter: un module de DEL qui émet une lumière dans une première direction de polarisation; une première photodiode qui reçoit une lumière émise à partir du module de DEL à travers une première plaque de polarisation présentant la première direction de polarisation; une seconde photodiode qui reçoit une lumière émise à partir du module de DEL à travers une seconde plaque de polarisation présentant une seconde direction de polarisation perpendiculaire à la première direction de polarisation; et un processeur qui détermine des informations de port concernant le dispositif électronique sur la base de l'intensité lumineuse d'une lumière détectée par rapport à chacune de la première photodiode et de la seconde photodiode. 전자 장치가 제공된다. 상기 전자 장치는 제1 편광 방향의 빛을 방사하는 LED 모듈, LED 모듈로부터 방사된 빛을 제1 편광 방향을 갖는 제1 편광판을 통해 수신하는 제1 포토 다이오드(photodiode), LED 모듈로부터 방사된 빛을 제1 편광 방향과 수직한 제2 편광 방향을 갖는 제2 편광판을 통해 수신하는 제2 포토 다이오드, 및 제1 포토 다이오드 및 제2 포토 다이오드 각각에 대하여 센싱된 빛의 광도(luminous intensity)에 기초하여 전자 장치의 착용 정보를 판단하는 프로세서를 포함할 수 있다.
