Abstract

Brake control assist for a four-castered walker for old people has been developed. The prototype system is equipped with a set of simple sensors, such as three-axis acceleration sensor and distance sensor. Our system estimates three walking states to control the application of the brake. Emergency strong brake can be predicted to prevent and/or forestall a fall. Individual characteristics related to brake control can be acquired within a short time and taken effect. In this paper, the implementation of brake control assist and its evaluations from performance and usability points of view are presented.
