Abstract: An augmented reality (AR) device is provided. The AR device includes a display configured to output light of a first polarization; a polarization-conversion reflector provided opposite to an output side of the display, the polarization-conversion reflector converting the light of the first polarization into light of a second polarization that is orthogonal to the first polarization and reflect the light of the second polarization; a waveguide having a flat plate shape, a normal line of a flat surface of the flat plate shape being inclined with respect to an optical axis of the light of the first polarization output from the display, a side of the waveguide being provided between the display and the polarization-conversion reflector; an input-coupler inputting the light of the second polarization into the waveguide; and an output-coupler outputting light propagating in the waveguide.

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.
