Abstract: A method, performed by an augmented reality device, for providing a guide for user activity, includes: obtaining, from a server of a policy provider, a policy comprising at least one activity about at least one of a location, a time, a space, or an object; inputting an image obtained through a camera to an artificial intelligence model, and recognizing, from the image, at least one activity of a user interacting with at least one of a location, a time, a space, or an object by using the artificial intelligence model; determining a policy performance level of the user by comparing the recognized at least one activity of the user with the at least one activity in the policy; and outputting, based on the policy performance level, a graphic user interface (UI) for providing the guide for the user activity on the policy.

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: The disclosure relates to augmented reality devices, and more particularly, to augmented reality glasses and methods for operating the same. An augmented reality display device is provided. The augmented reality display device includes a projection system, an optical compensator positioned after the projection system, and a flexible waveguide. The flexible waveguide can change its curvature and comprises an input diffraction grating and an output diffraction grating. The optical compensator is configured to introduce pre-distortion to the image and optically zoom the image received from the projection system, the pre-distortion in the image and optical zoom of the image being opposite to those introduced by the flexible waveguide to the undistorted image in accordance with chosen radius of the flexible waveguide. Flexible diffraction grating distorts the pre-distorted image. The output diffraction grating outputs undistorted image to a user's eyes.

Abstract: The disclosure relates to augmented reality devices based on a curved waveguide. An augmented reality device is provided. The augmented reality device includes a projection system to project an undistorted image, an input optical compensator located on the path of light rays out-coupled from the projection system, a curved waveguide comprising an input diffractive optical element and an output diffractive optical element. The output diffractive optical element performs the function of an output optical compensator that converts the light beams of a distorted image at the output of the waveguide into parallel light beams to output an undistorted image. Augmented reality glasses comprising an augmented reality device are also proposed. There is provided the ability to project a virtual image without aberrations, distortions and doubling of the image.
