Abstract
A wearable device is disclosed. The wearable device comprises: a camera; a sensor; a display; a laser projector; and a processor for identifying a user's sight line on the basis of sensing data obtained by the sensor, identifying location information of at least one object included in an image obtained by the camera, and controlling the laser projector to provide, on the display, augmented reality (AR) information related to the object on the basis of the identified user's sight line and location information of the object, wherein the laser projector comprises: a light emitting element for emitting a laser light; a focus adjusting element for adjusting a focus of the emitted laser light; and a scanning mirror for controlling a scan direction of the light having the adjusted focus, and the processor controls a driving state of the focus adjusting element on the basis of the identified user's sight line and location information of the object.
