Abstract: A method, by an augmented reality device, of measuring a depth of an object includes determining, from a dot-pattern and a surface-pattern, a pattern of light to be emitted for measuring the depth of the object, identifying, from within an entire area of a pattern generator, a partial area of a light source unit corresponding to an area for the determined pattern, emitting light through the area for the determined pattern, by activating the identified partial area of the light source unit, receiving light reflected from the object; and measuring the depth of the object based on the emitted light and the received reflected light.

Abstract: An eye tracking apparatus includes: a light source module including a light source and a scanning mirror, the light source being configured to provide light toward an eye region of a user while a direction of the light is changed at intervals of a predetermined time period under control of the scanning mirror; and a dynamic vision sensor (DVS) camera module configured to generate an image based on a variation in an amount of light reflected from the eye region of the user.

Abstract: A head-mounted display device includes an eye tracking sensor configured to obtain eye information by tracking both eyes of a user, a depth sensor configured to obtain depth information about one or more objects, and a processor configured to obtain information about a gaze point based on the eye information, and determine a measurement parameter of the depth sensor based on the information about the gaze point.
