1. A wearable device with an optical sensor equipped on a side part, comprising:
a body part;
a strap unit to fix the body part to a wrist part of a user;
an optical sensor unit including the optical sensor installed on a side surface of the body part, wherein the optical sensor unit is to acquire illuminance information;
a determining unit to determine whether the wearable device is worn such that the side surface on which the optical sensor is disposed is directed to fingers of the user;
a display unit which is provided on the body part to display predetermined information; and
a control unit to control an output direction of the predetermined information through the display unit to be a normal output direction corresponding to a user's gaze direction when the side surface on which the optical sensor is disposed is directed toward the fingers of the user and to control the output direction of the predetermined information through the display unit to be an abnormal output direction which does not correspond to the user's gaze direction when the side surface on which the optical sensor is disposed is directed away from the fingers of the user.
