Sensing human movement of mobility and visually impaired people

This paper studies human movement of both mobility and visually impaired people using mobile sensing devices as the first step toward creating an accessible information base. Nine mobility impaired persons conduct an experiment of wheelchair moving, and the visualized sensing results mapped on Googlemap is compared with their subjective feelings. Also, one blind person conducts an experiment of walking with a walking assistant. The sensing results show that a single accelerometer enabled to detect walking, descending and waiting behaviors.
