Electronic device and method for eye-tracking of user and providing augmented reality service thereof

Abstract

According to various embodiments of the disclosure, an electronic device includes: a frame; a glass module comprising a glass supported by the frame; a support rotatably connected to the frame; a display module comprising display circuitry configured to project an image to the glass module; a front camera disposed in at least one of the frame or the support configured to photograph the front of the frame; a light emitting unit comprising light-emitting circuitry configured to radiate light toward the rear of the frame; and an eye tracking camera disposed in the frame configured to photograph the rear of the frame and including a lens assembly including at least one lens, wherein the eye tracking camera is configured to form a field of view (FOV) to include both a left eye and a right eye of a user based on an object distance, which is a distance between the lens assembly and an object, being a first distance corresponding to a distance between the lens assembly and the left eye and/or the right eye of the user wearing the electronic device, wherein an absolute value of a distortion value of the lens assembly is equal to or less than a threshold value capable of tracking a pupil movement of the left eye and the right eye with respect to light incident from a region of interest (ROI) within a certain range from an outermost portion to the inside among regions corresponding to the FOV.
