摘要： 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.

摘要： Provided are a device and method for correcting the vision of a user and performing calibration. A method, performed by an augmented reality device, of performing gaze tracking sensor calibration based on a gaze of a user includes outputting at least one first character in a preset size through a waveguide of the augmented reality device, obtaining at least one first input for the at least one first character, obtaining at least one piece of first gaze information detected through a gaze tracking sensor of the augmented reality device at a time point at which the at least one first input is obtained, comparing the at least one first character with the at least one first input, and determining a first refractive power to be a refractive power of the varifocal lens of the augmented reality device, based on a result of the comparing.
