Abstract
Disclosed is a wearable device. The wearable device includes an optical signal transmission unit configured to transmit optical signals, an optical signal sensing unit configured to receive reflected optical signals generated upon reflection of the optical signals by an object, a data processing unit configured to process the received reflected optical signals, and a key determination unit configured to sense a user's key input motion based on data acquired by processing the reflected optical signals and to generate an input value matching the key input motion.
