    Abstract: An augmented reality (AR) device for obtaining depth information of an object in a real world, includes: a gaze tracking sensor configured to obtain a gaze point by tracking a gaze direction of a user's eye; a depth sensor configured to obtain depth information of the object; a memory storing one or more instructions; and at least one processor configured to execute the one or more instructions to: determine a region of interest (ROI) confidence level indicating a degree to which at least one partial region within a field of view (FOV) of the AR device is predicted as an ROI, based on at least one of a moving speed, an acceleration, a fixation time, a fixation number, or a location of the gaze point; determine an ROI based on the ROI confidence level; and set a parameter for controlling an operation of the depth sensor to obtain depth information of the object within the ROI.

    Abstract: An electronic device that outputs at least one calibration point through a display, obtains gaze information corresponding to the at least one calibration point by using a gaze tracking sensor in response to an output of guide information instructing a user wearing the electronic device to gaze at the at least one calibration point, obtains a gaze accuracy corresponding to the at least one calibration point based on the obtained gaze information, determines a gaze zone-specific resolution based on the gaze accuracy corresponding to the at least one calibration point, and outputs an image through the display based on the determined gaze zone-specific resolution.

    Abstract: An operating method of an AR glass apparatus includes obtaining a preview image through a camera of the apparatus, tracking a gaze direction of a user wearing the apparatus, determining an object of interest in the preview image based on the tracked gaze direction, obtaining local motion information indicating a movement of the object of interest by tracking the movement of the object of interest, measuring a movement of the apparatus, obtaining global motion information indicating a movement of a background region included in the preview image based on the measured movement of the apparatus, adjusting a degree of exposure based on the local motion information and the global motion information, and photographing a front of the apparatus through the camera having the adjusted degree of exposure.
