A.A.V. / Traffic police vest

In order to perform an effective and safe guidance solution for traffic police and command staffs, we propose a hand signal driven LED vest display to solve the problems of using conventional warning vests and baton light. The accelerometers attached on the traffic police's hands provide the information of gesture, and the information is further translated as the corresponding hand signal patterns. Then, the recognized hand dynamic signal patterns are displayed on the LED vest display.
