This study is about e-Book program based on human-computer interaction(HCI) system for physicallyhandicapped person. By acquiring background knowledge of HCI, we know that if we use vision-based interface wecan replace current computer input devices by extracting any characteristic point and tracing it. We decided betweeneyesas a characteristic point by analyzing facial input image using webcam. But because of three-dimensional structureof glasses, the person who is wearing glasses wasn't suitable for tracing between-eyes. So we changed characteristicpoint to the bridge of the nose after detecting between-eyes. By using this technique, we could tracerotation of head in real-time regardless of glasses. To test this program's usefulness, we conducted an experimentto analyze the test result on actual application. Consequently, we got 96.5% rate of success for controlling e-Bookunder proper condition by analyzing the test result of 20 subjects.
