Tokyo Metro has started testing an audio guidance system that can assist passengers who are blind or have low vision with directions in train stations, reports the Japan Today.
The audio guidance system using QR codes system has been installed at Shinkiba and Tatsumi stations along the Yurakucho subway line.
Passengers with vision disabilities can receive audio directions by scanning a QR code installed on the Braille blocks with a smartphone camera.
Tokyo Metro confirmed that the audio guidance system can effectively be used at multiple stations. Based on the results of the tests, Tokyo Metro has announced plans to expand the installation of these QR-coded stickers in other stations as well.
