| Abstract(in English) | Our aim is to develop an eye switch that uses eye movements as a means of supporting communication in ALS patients. In previous research, we developed a eyeglasses-type switch using a contact-type wearable camera. However, there remained the issue of putting a burden on users when wearing the device. Therefore, in this research, we will develop a non-contact eye-switch that uses a stationary infrared camera and an infrared LED. The difference in internal processing from previous studies is that the captured image is an eye image in the previous study, whereas in this study it is a facial image that shows the user's entire face. Therefore, we introduce a process to extract the eye ROI by applying face and facial landmark detection in the image processing section. When we collected data from six healthy subjects and conducted a quantitative evaluation, we found that although the accuracy was lower than in previous studies, it was still accurate enough for practical use. Furthermore, we implemented a real-time system and confirmed its operation. |
