The guide belt is a belt that informs blind people about physical obstacles, e.g. walls, that are located in front of them. It can be deployed indoor and outdoor and is proposed as another assistive device next to a guide dog and a white stick. Three ultrasonic sensors are used for distance measurements. They are mounted at the belt with different angles to get distance measurements for different obstacle heights. Accustic signals are used to draw attention to front-located obstacles and to inform about the obstacle’s distance.
The project was realized by B. Enders-Müller and D. Knollmann.
