Hazard Detection System by Using the Kinect Sensor for Game in a Handle Type Electric Wheelchair

To ensure the safety of the handle type electric wheelchair at the time of day or night, we propose the hazard detection system by using the Kinect sensor for game, and carry out the performance evaluation of the system. In particular, we propose the detection method of the hazard object at the time of day or night, the size determination of the hazard object to be detected and the hazard detection area on the basis of the reaction time of the elderly people and Japan Industrial Standards (JIS). And then, after we build the hazard detection system, we conduct driving experiments that are the moving hazardous object detection in the time of day, and the stationary and the moving hazardous object in the time of day and night, and perform the evaluation of the detection ratio and the estimation accuracy of the system. These results show the feasibility of the proposed system in the handle type electric wheelchair.
