Abstract
A gaze detection apparatus and method are provided. The method includes storing, by a controller, a reference gaze, a first reference vector, and a second reference vector. An image is then captured by an imaging device that includes user eyes. In addition, the controller detects central points of a pupil and an eyeball from the captured image and generates a gaze vector for one eyeball and a normal vector of a plane at which three central points are formed, when the three central points are detected. A first rotation angle and a second rotation angle are calculated by comparing the gaze vector and the normal vector, respectively, with the first reference vector and the second reference vector and a mean value thereof is calculated. Further, a gaze is then detected by rotating the reference gaze as much as the mean value.
