a light source module;
a display module comprising at least one layer and being divided into a first display region, in which at least one object related to an augmented reality service is displayed, and a second display region, which corresponds to a remaining region of a display region of the display module other than the first display region;
a camera module; and
a processor operatively connected to the light source module, the display module, and the camera module,
wherein the processor is configured to:
control the light source module to emit light along a waveguide formed in the at least one layer of the display module,
use the camera module to detect, based on at least one pattern structure formed in the waveguide, at least a part of the light, which has been reflected from a user's pupil, and
track movement of the user's pupil, based on the detected light, and
wherein the waveguide is at least partially formed based on the second display region of the display module.
