Abstract
A method and device for estimating a gaze distance of a user using hybrid scheme may accurately estimate a gaze distance of a user robustly against a difference in physiological characteristics of the user and a change in external environment using information of a binocular image and information of a depth image in a complementary manner by determining a final gaze distance of the user based on a first gaze distance of the user estimated based on a binocular convergence angle of the user and a second gaze distance of the user estimated based on a depth value of the gaze point of the user.
