Abstract
Disclosed herein are a method for providing a composite image based on optical transparency and an apparatus for the same. The method includes supplying first light of a first light source for projecting a virtual image and second light of a second light source for tracking eye gaze of a user to multiple point lights based on an optical waveguide; adjusting the degree of light concentration of any one of the first light and the second light based on a micro-lens array and outputting the first light or the second light, of which the degree of light concentration is adjusted; tracking the eye gaze of the user by collecting the second light reflected from the pupil of the user based on the optical waveguide; and combining an external image with the virtual image based on the tracked eye gaze and providing the combined image to the user.
