視覚障害者歩行案内に用いる車輪付き杖装置の停止方法に関する研究

抄録

We have developed a wheeled cane device to guide the visually impaired. For safe walking guidance, the device must be able to guide stopping to avoid collision. Brakes on the wheels transmit stopping to the user when an LRF on the device measures obstacles on the route of guidance. Profile of the braking force and the timing to apply the brake are designed through trial by the visually impaired. Walking guidance experiments are performed by 6 visually impaired at shopping malls to illustrate availability of the stopping method.
