Classification: CPC G | IPC G

Claim 15:
16. The method of claim 11, further comprising:
determining a brightness of light of a virtual image output to a waveguide of the AR device based on the measured pupil size;
obtaining, by using the gaze tracking sensor, three-dimensional position coordinate information on a gaze point at which a gaze direction of a left eye and a gaze direction of a right eye converge; and
obtaining distance information on a distance between the gaze point and the virtual image by measuring a distance between the three-dimensional position coordinate information on the gaze point and a region in which the virtual image is displayed,
wherein the adjusting of the brightness of the light of the virtual image comprises adjusting the brightness of the light of the virtual image based on the pupil size and the distance information on the distance between the gaze point and the virtual image.
