This study paid attention to the disagreement of the eye-contact in teleconference caused by the separation between the input camera and output monitor devices. Then the authors proposed the Eye-Contact Camera System for generating eye-contacted motion images to the receiver. In this system, iris contour is extracted after the face region extraction, the vertical and horizontal directions of the glance are calculated based on the relation among positions of the monitor, camera and receiver, and finally the iris center coordinates are shifted in the image so that the partner looks just looking at him, and vice versa. This paper suggested that improved iris detection for coping with roll rotation of face, and implemented the system on note PC with web-camera for evaluating the usability. As a result, iris detection rate was improved from 32% to 65%, and usability More than 92% (25/27) users gave positive evaluation to eye-contacted image.
