Assistive instruments such as textured paving blocks and acoustical traffic signals are installed for helping visually impaired people to walk comfortably and avoid traffic accidents, who have any inconvenience to move outside. Though these precipitous situations of accessibility progress affect their migration pathway for their destination, up-to-date accessibility information is difficult to gain quickly because of local information disclosure. Thus it is necessary to develop a comprehensive system that appropriately acquires and arranges scattered accessibility information, and then presents this information intuitively. However, these systems present volunteers with difficulties when they are gathering accessibility conditions and then organizing them. Also, most of the volunteers do not know the current situations of acoustical support systems for the visually impaired. In this study, our final goal is to establish an efficient scheme to share the conditions and places of the acoustical support syste... |
