    Abstract: 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.

    Abstract: A method, performed by an augmented reality device, for providing a guide for user activity, includes: obtaining, from a server of a policy provider, a policy comprising at least one activity about at least one of a location, a time, a space, or an object; inputting an image obtained through a camera to an artificial intelligence model, and recognizing, from the image, at least one activity of a user interacting with at least one of a location, a time, a space, or an object by using the artificial intelligence model; determining a policy performance level of the user by comparing the recognized at least one activity of the user with the at least one activity in the policy; and outputting, based on the policy performance level, a graphic user interface (UI) for providing the guide for the user activity on the policy.

    Abstract: A method, performed by an augmented reality (AR) device including a vision correction lens, of detecting a gaze of a user is provided. The method includes obtaining lens characteristic information about the vision correction lens arranged to overlap a light guide plate in a gaze direction of the user, emitting light for gaze tracking toward a light reflector through a light emitter, wherein the emitted light is reflected by the light reflector and then directed to an eye of the user, receiving a light reflected by the eye of the user through a light receiver, obtaining an eye image of the user based on the light received, adjusting the eye image of the user based on the lens characteristic information about the vision correction lens, and obtaining gaze information based on the adjusted eye image.

    IPC: G06F3/01

    Abstract: Provided is an electronic device for detecting lost portions of a field of vision and distorted portions of a field of vision and storing these in a vision map. The lost portions and distorted portions are identified in cooperation with the user by means of virtual image superposition on a real scene, audible requests to the user, gesture inputs provided by the user and gaze tracking. The electronic device may detect an object and provide visual information to a user when the object is in a lost portion or distorted portion of the field of vision.
