Claim One:
1. A method of predicting an eye position, the method comprising: receiving a first image photographed by a camera; obtaining current eye position coordinates x n in the first image by detecting a face of a user in the first image; calculating a current velocity v n based on the current eye position coordinates x n , a previous eye position coordinates x n−1 in a second image generated before the first image, and a difference between points in time at which the first image and the second image are photographed; and updating a first history of a velocity of an eye movement by adding the current velocity v n to the first history; determining a current prediction velocity v p n of the eye movement based on the first history and a previous prediction velocity v p n−1 of the eye movement with respect to the second image; and predicting current prediction eye position coordinates x p n using the current prediction velocity v p n .
