摘要： Provided is an augmented reality device including a variable focus lens, an eye tracking sensor configured to emit light to eyes of a user, receive the light reflected by the eyes of the user, and detect a plurality of feature points based on the light reflected by the eyes of the user, and at least one processor configured to obtain information with respect to eye relief, which is a distance between the eyes of the user and the variable focus lens, based on position information of the plurality of feature points detected by the eye tracking sensor, obtain information with respect to a gaze point at which gaze directions of the eyes of the user converge, and an interpupillary distance of the eyes of the user, based on the plurality of feature points, and determine a position of a focal region of the variable focus lens based on the information with respect to the eye relief, the gaze point, and the interpupillary distance.

摘要： 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.

摘要： 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.
