Abstract
A wearable device is illustrated. The wearable device has a body, at least one light emitting unit, at least one light sensing unit and an action recognition module. The wearable device is suitable for wearing on a movable part of a user. The light emitting unit is disposed on an inner side of the body, wherein the light emitting unit emits a light beam illuminating at least a portion of the movable part. The light sensing unit operatively senses the light beam reflected by the at least portion of the movable part and generates a light sensing signal. The action recognition module is configured to operatively determine a function that corresponds to an action of the user.
