    Abstract: 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.

    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: An electronic device for displaying augmented reality (AR) includes: an optical engine configured to output light of virtual image; a waveguide from which the light of the virtual image is output and through which light of a real scene is transmitted; an optical shutter configured to transmit or block the light of the real scene; a focus tunable lens configured to adjust a focal length for the light of the virtual image output from the waveguide; and one or more processors configured to, during a first period, control the optical shutter to block at least part of a first light of the real scene, and control the focus tunable lens to have a first focal length, and during a second period, control the optical shutter to transmit a second light of the real scene, and control the focus tunable lens to have a second focal length different from the first focal length.
