With the trend of the aging society, how to take good care of the elders has become the significant issue. Based on the techniques of Kinect interface and indoor positioning, this paper develops a power wheelchair control system to improve the living quality of disabled elders. To realize hand gesture recognition with Kinect interface, the disabled elder uses hand gesture to call the wheelchair. The power wheelchair moves to the location of disabled elder automatically. At the same time, the elder can request the power wheelchair to any places via a touch panel. When the disabled elder does not need the wheelchair furthermore, the power wheelchair will go back to its parking location. [ABSTRACT FROM PUBLISHER]
