  • Patent number: 11992454
    Abstract: A movement support system for a physically disabled person comprises: movement support tool; a plurality of passage units; and control apparatus. The movement support tool comprises: magnetically attractive part; non-contact tag part; reception part; input part; output part; and control part. The passage unit comprises: electromagnet part, non-contact reading part, transmission part, and control part. The control apparatus acquires the destination information and the user ID from the movement support tool; acquires the user ID and the position information from the first passage unit closest to the movement support tool; and calculates route from the position information to the destination information; generates guidance based on the route and position information; outputs the generated guidance from the movement support tool; and controls each of the electromagnet part of the plurality of passage units so as to attract (pull) the magnetically attractive part in traveling direction of the route.
