In Japan, accidents are occurring when visually impaired people go out. For example, a collision with an obstacle such as a person or a wall, or a fall from the station platform. A current measure for this problem is a voice guidance. However, visually impaired people place importance on auditory information. Therefore, it is difficult for them to hear surrounding sounds during listening the voice guidance. There is a previous research that trying to guide the visually impaired people to their destination by vibration transmission. However, although this study have realized the guidance of the visually impaired people to their destination without interrupting environmental sounds, this method cannot correct the veering in real time. For above reason, we propose a veering correction system by vibration transmission, which does not disturb acquisition of auditory information. This is a system that gives them vibration by wearing a vibration motor on their shoulders and corrects the veering. In this article, we conducted verification experiment of the effectiveness of the veering correction by vibration transmission as a preliminary study in the development of the veering correction system. As a result of the research, we were able to keep the deviations from over 100 cm to less than 100 cm. As a conclusion, vibration transmission is effective as a method of correcting the veering of visually impaired people. |
