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.

Augmented reality device including variable focus lenses and operating method thereof

Provided is a device for displaying augmented reality including an optical engine configured to output light of a virtual image, a waveguide configured to output light of the virtual image and transmit light of a real scene, a first lens part and a second lens part, and a processor, the first lens part being configured to tune a focus of the virtual image and including a first focus-tunable lens having a refractive power tunable by the processor and a fixed refractive lens having a refractive power, the second lens part being configured to compensate distortion of the real scene and including a second focus-tunable lens having a refractive power that is tunable by the processor, and the processor being further configured to determine the first refractive power based on vision information of the user, attribute depth information of the virtual image, and fixed refractive power of the fixed refractive lens.

Device and method for displaying augmented reality

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.
