Abstract
AbstractWe have studied a man–machine interface system by using an eye gaze detection technique. Target users for this system are ordinary people and orthopedically impaired people who have no movement in their hands and head. Ordinary people can use this system under the condition that they do not move their head. An algorithm for detecting the center of the iris is proposed in this paper. An image of the eye is captured with a small video camera and the center of the iris is obtained by filtering in color space and pattern matching with a ring‐shaped template. Improvement of the pattern matching speed is also described and the effectiveness of the reduction of calculation costs is shown. Furthermore, the accuracy of the eye gaze detection was evaluated. © 2009 Wiley Periodicals, Inc.
