1. A wearable device comprising:
- 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, wherein;
the optical signal transmission unit transmits a first optical signal and a second optical signal having different first and second wavelengths;
the optical signal sensing unit receives a first reflected optical signal caused by the first optical signal and a second reflected optical signal caused by the second optical signal;
the data processing unit generates pattern information regarding blood vessels of the object based on the first reflected optical signal and the second reflected optical signal; and
the key determination unit senses the user'"'"'s key input motion by comparing information regarding blood vessels changed according to the user'"'"'s key input motion with the pattern information.
