Development of Plantar Visualization System

Abstract

In this study, we developed a novel sensing system for the planta while walking on any surface and in any condition. A plantar image is reflected at the reflecting surface and photographed by a camera attached to a shoe. The obtained visual information of plantar can provide the detailed information on the plantar surface unlike pressure and IMU data obtained from conventional sensors. We investigated the relationship between the activity in the toe area and stumbling experiences. The results indicate that high toe activity is associated with the group which did not have stumbling experiences and low toe activity is associated with the group which have stumbling experiences.
