“…The development of the interface using eyes has been done flourishingly and these apparatus attract attention as an intention transmission device for severe ALS patients now in the field of welfare. For the detection of the gaze point, the method using the EOG (Electro-oculogram) [1] and the colored contact lenses [2] are suggested. However, the EOG needs amplifier equipment and it is a lot of hassle for user to put on a contact lenses.…”

This paper describes a man machine interface based on gazing input without user's body restrictions. Gazing points forward to the side directions were estimated by the relative distance of an iris and the outer corner of left and right eyes. Whether or not the user gazes the camera was recognized by the intersection of the two perpendicular bisectors derived by the position of a cornea and the eyelid edges. The suggested recognition system was applied to the operations of the page turner machine. It could judge the user's states of both reading a book and operating the machine by the special feature points on an eye.

“…In this method, it is necessary that the colour of the iris be black. LOS detection using irises of any other colour has not been attempted, although non-contact LOS detection using coloured contact lenses has been studied [8]. This method is not in¯uenced by the colour of the iris.…”

The human-machine interface is an important factor in computer systems. It is thought that line-of-sight (LOS) detection technology will allow significant advances in this field. The current study is intended to be a step in that direction. Two processes were established to fulfil the plan of this study. In process 1, a non-contact LOS detection method was developed that is able to be used freely and naturally using image processing. Markers or equipment worn by the user are no longer needed to detect LOS. In process 2, the new detection method was applied in developing an ON/OFF control equipment system using human LOS. Two key points are that the user is able to move freely and naturally and that only LOS is required to operate these systems.

“…Iris detection using color images has also been proposed [6]; specifically, an image is converted into the YUV color space, thresholds are found from histograms of the color difference ratio U/V for each pixel, and the binarized eye images thus obtained are merged with binarized intensity images. In addition, there is a method using tinted contact lenses [10], but this method puts a strain on the users and may cause discomfort, especially to those who do not wear contact lenses every day. Aiming at high-speed iris detection, a method was proposed to extract face areas and eye areas from images taken by an external camera, and then to identify the iris contours by using the Hough transform [11].…”

SUMMARYWe 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.
