Wearable Device and Method for Controlling the Same

摘要

Provided are a wearable device and a method for controlling the same. The wearable device may include a distance sensor unit configured to output a first signal for determining a distance between a user and the wearable device and to receive the first signal reflected from the user. The wearable device may also include a biometric sensor unit configured to output a second signal for determining biometric information of the user and to receive the second signal reflected from the user, and a controller configured to determine the distance based on the received first signal and to obtain the biometric information of the user based on a change in an attribute of the received second signal. The controller may control the biometric sensor unit to output the second signal if the determined distance is equal to or less than a reference distance.

1. A wearable device comprising:
a distance sensor unit configured to output a first signal for determining a distance between a user and the wearable device and to receive the first signal reflected from the user, when the wearable device is worn by the user; a biometric sensor unit configured to output a second signal for determining biometric information of the user and to receive the second signal reflected from the user; and a controller configured to determine the distance based on the reflected first signal and to obtain the biometric information of the user based on a change in an attribute of the reflected second signal, wherein the controller controls the biometric sensor unit to output the second signal if the determined distance is equal to or less than a reference distance.
