<P>PROBLEM TO BE SOLVED: To construct a visual line input communication system using eyeball motion for enabling stay-home work to be carried out by selecting an intended item on a display screen, by obtaining a face image of a patient by using a video camera to detect a visual line direction of the patient by image processing in a contactless manner, by inputting the visual line only by an eyeball function by eyeball motion and the opening-closing action of an eyelid, and by operation by a virtual board with a switching operation, by setting, as an issue, development of the visual line input communication system using eyeball motion. <P>SOLUTION: This method is so structured that a differential image is obtained, by making an examinee open and close his or her eyes, from an image formed by capturing the entire face of the examinee; then, templates of eyes and eyebrows are registered; and the visual line direction is detected by comparing data obtained in calibration with data obtained from the input image. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
