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.

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: 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.
