PROBLEM TO BE SOLVED: To provide a visually-challenged person support system that allows a visually-challenged person to pass/traverse a road safely.SOLUTION: A visually-challenged person support system 10 performs visible light communication between a traffic light 12 and a visually-challenged person's transceiver 14. The traffic light 12 includes: a plurality of light-emitting elements 16, a driving unit for causing the light-emitting elements 16 to emit light as a signal of visible light communication; a control unit 20 for switching the light-emitting elements 16 to emit light; a light-receiving element 22 for receiving the signal of visible light communication; and a demodulation unit 24 for demodulating the signal of visible light communication received by the light-receiving element 22. The visually-challenged person's transceiver 14 includes: a light-emitting element 34; a driving unit 36 for causing the light-emitting element 34 to emit light; a light-receiving element 38; a demodulation unit 40 for demodulating a signal of visible light communication received by the light-receiving element 38; a control unit 42 for switching between light emission and light reception; and an output unit 44 for outputting the state of signal display.SELECTED DRAWING: Figure 1

    【課題】視覚障がい者が安全に道路を通行したり横断したりできる視覚障がい者支援システムを提供する。【解決手段】視覚障がい者支援システム10は、信号機12と視覚障がい者用送受信機14とで可視光通信をおこなう。信号機12は複数の発光素子16、発光素子16を可視光通信の信号として発光させる駆動部、発光させる発光素子16を切り替える制御部20、可視光通信の信号を受光する受光素子22、受光素子22が受光した可視光通信の信号を復調する復調部24を備える。視覚障がい者用送受信機14は、発光素子34、発光素子34を発光させる駆動部36、受光素子38、受光素子38が受光した可視光通信の信号を復調する復調部40、発光と受光を切り替える制御部42、信号表示の状態を出力する出力部44を備える。【選択図】図1
