Therefore, the wearable device 100 may control the sensor 110 to capture the vein image in order to identify the user wearing the wearable device 100.
In operation 830, the wearable device 100 may identify the user wearing the wearable device 100 by comparing the captured vein image with the registered vein images.
In operation 840, the wearable device 100 may display the music list of the identified user on the display unit 120. The wearable device 100 may control the display unit 120 so as to display the music list of the identified user.
Since the wearable device 100 provides the music list to the user through vein authentication, the wearable device 100 may provide music registered by the user wearing the wearable device 100 even in the absence of a separate input.
