Abstract: An augmented reality (AR) device including a variable focus lens of which a focal length may be changed by adjusting refractive power and adjusting the position of a focus adjustment region of the variable focus lens according to a direction of the user's view. The AR device may obtain an eye vector indicating a direction of the user's view using an eye tracker, adjust a refractive power of a first focus adjustment region of a first variable focus lens to change a focal length for displaying a virtual image, and complementarily adjust a refractive power of a second focus adjustment lens with respect to the adjusted refractive power of the first focus adjustment region.

Abstract: Provided is a method, performed by an augmented reality (AR) device, of measuring a user's vision. The method includes: obtaining, by using a camera of the AR device, a background image including an image of at least one physical object; identifying an edge of the image of the at least one physical object in the background image; determining a first region for measuring the vision of the user on the background image based on the edge of the image; determining a second region corresponding to the first region on a display of the AR device; outputting a virtual object for measuring the vision of the user to the second region; obtaining a user input signal for vision measurement after the outputting the virtual object; and determining a vision prescription value of the user based on the user input signal.

Abstract: Provided is a method of identifying a hand of a genuine user wearing a wearable device. According to an embodiment, the method includes using a sensor included in the wearable device to recognize a hand located in a detection area of the sensor; estimating a position of a shoulder connected to the recognized hand based on a positional relation between the orientation of the recognized hand and at least one body part connected to the recognized hand; and using information about a probability of a shoulder of the genuine user being present in the estimated position to determine whether the recognized hand is a hand of the genuine user.

Abstract: A method, by an augmented reality device, of measuring a depth of an object includes determining, from a dot-pattern and a surface-pattern, a pattern of light to be emitted for measuring the depth of the object, identifying, from within an entire area of a pattern generator, a partial area of a light source unit corresponding to an area for the determined pattern, emitting light through the area for the determined pattern, by activating the identified partial area of the light source unit, receiving light reflected from the object; and measuring the depth of the object based on the emitted light and the received reflected light.

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.
