The demonstration experiment was conducted at Tsukuba Station of the Tsukuba Express and the surrounding bus terminals. Five visually impaired students from Tsukuba University of Technology participated.
When the students scanned the QR code written on the braille block at the bus stop with their smartphones, the candidate destination was read aloud. As the students chose the station platform as their destination, QR codes were read one after another, and a voice was played providing directions to the platform. "The directions were easy to understand, so I was able to move around places I didn't know much," a first-year student said.
