Abstract: An electronic device performing a method of tracking a user's gaze of an electronic device and outputting an augmented reality (AR) image is provided. The metho includes outputting a first light which is a structured light at a first time point toward the user's eyes, outputting a second light at a second time point toward the user's eyes, acquiring a first image in response to the output of the first light at the first time point, acquiring a second image in response to the output of the second light at the second time point, synthesizing the first image and the second image to create a third image, calculating first coordinate values, which are coordinate values of pupils of the user's eyes on the basis of the third image; and detecting a gaze direction on the basis of the first coordinate values.

Abstract: An electronic device is provided. The electronic device includes a light source module, a display module including at least one layer, a camera module, and a processor operatively connected to the light source module, the display module, and the camera module. The processor may emit light through the light source module along a waveguide formed in the at least one layer of the display module, may use the camera module to detect, based on at least one pattern structure formed in the waveguide, at least a part of the light, which has been reflected from a user's eyeball, and may track the movement of the user's eyeball, based on the detected light.

Abstract: A wearable electronic device with a display is provided. The wearable electronic device includes: a stereo camera configured to detect infrared light, a self-luminous display including a plurality of visible light pixels configured to output visible light corresponding to a virtual object image and a plurality of infrared pixels configured to output infrared light, an optical waveguide configured to output the virtual object image by adjusting a path of the visible light, a first control circuit configured to supply driving power and a control signal to the self-luminous display, and a second control circuit configured to supply driving power and a control signal to the stereo camera. The optical waveguide includes a half mirror configured to output reflected infrared light and transmitted infrared light in response to the output infrared light.

Abstract: Augmented reality (AR) glass is provided. The AR glass includes a first light source which emits display light for displaying an AR image, an eye tracking (ET) sensor for detecting reflected light reflected from the eye of a user, glass, which includes a display waveguide for guiding the display light, emitted from the first light source, to a display area of a see-through display, and an ET waveguide for guiding the reflected light to the ET sensor, and a processor electrically connected to the first light source and the ET sensor, wherein the processor controls the first light source so as to emit the display light, and tracks, through the ET sensor, the gaze of the user on the basis of the detected reflected light.
