Abstract: A method of determining an arm posture of a user may include determining a distance from a first part of a body of the user to a second part of a lower arm of the user based on length information of a cable generated by a first sensor arranged on at least a part of the body of the user, determining a first rotation angle of the lower arm in a three-dimensional space based on rotation information generated by a second sensor attached to the second part, determining a second rotation angle of an upper arm in the three-dimensional space based on the distance from the first part to the second part and the first rotation angle of the lower arm, determining a position of the upper arm and a position of the lower arm in the three-dimensional space based on the first rotation angle of the lower arm and the second rotation angle of the upper arm; and determining the arm posture based on the position of the upper arm and the position of the lower arm.

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.
