Japan finds a solution to help blind people navigate stations safely

OSAKA — The latest technology is increasingly being employed to improve safety of blind people and convenience when using railway facilities

Among these initiatives, West Japan Railway Co. (JR West) on Sept. 3 revealed its new navigation system, which uses a combination of smartphone technology and QR codes to convey information about train stations, to the press in the western Japan city of Kobe. People with visual impairments consider train platforms as similar to dangerous bridges with no handrails, but people including those involved with developing the safety system have high hopes for the scheme.

On the morning of Sept. 3 at the Sanyo Shinkansen section of Shin-Kobe Station, a man using a white cane held out his smartphone as he steadily walked on the floor’s tactile paving. QR codes were seen on the paving blocks situated at important points, including those that connect ticket barriers to platforms, and at sections where the path splits or reaches a flight of stairs. When the man reached one of the QR codes, a voice would play from his phone, and guide him to the intended destination he inputted earlier.

The man testing the technology for the first time, a 30-year-old resident of Osaka’s Suminoe Ward who works for an association, smiled and said, “I’d never used Shin-Kobe Station before, but I could walk around at my normal speed. I felt happy and like I was doing something new.”

Progress Technologies, a firm based in Tokyo’s Koto Ward, has been developing the navigation system used at the station since 2016. In the eastern Japan region of Kanto, they have already worked in cooperation with Tokyo Metro Co. to do on-site tests of the system at subway stations. In the Kansai region in western Japan, the company intends to do tests to see if the system can provide accurate information for trains with different numbers of carriages and different destinations, among other considerations. The company’s head, Yuichi Konishi, said, “In the future we’ll use artificial intelligence (AI), and be able to detect the locations of tactile blocks and objects people might walk into.”

Behind the development of technologies to help people with visual impairments is the now widespread use of smartphones in society and improvements in image recognition technology. In February 2020, Kyocera Corp. announced it was developing a “smart cane.” The concept involves having signal-emitters installed at specific points, such as on the edges of platforms and the parts where train cars connect. In the event that a smart-cane user approaches the emitters, they would cause vibrations in the cane, which is fitted with a receiver, and issue a spoken warning of the dangers from the person’s phone. As the project just started in 2019, the company reported that it wishes to do on-site tests at train stations.

From June, Kintetsu Railway Co. has outfitted an AI system at the west Japan city of Nara’s Yamato-Saidaiji Station. The entrance to the ticket barrier has a camera installed, and the AI automatically picks up when a person with a cane or a wheelchair user passes its lens. Once it has done so, it informs a member of staff responsible for helping people that they are there.

The railway firm said that as some people who may need help struggle to approach others to ask for assistance, it hopes the new system will “prevent people being overlooked.” It also said it would continue to improve its accuracy and look into implementing it at more stations.

But according to organizations including the Ministry of Land, Infrastructure, Transport and Tourism and the Japan Federation of the Visually Impaired, the schemes have issues, including that the uptake of smartphones among impaired people varies, that stations are host to many different sounds that make phones hard to hear, that not all visually impaired people use canes, and that users could be mistaken for people using their phones while walking.

The federation’s director, Masaki Hashii, emphasized that while “there is no change in the importance of station staff and passengers offering help,” he said that “the ‘fear’ that comes with using train stations is deep-rooted. But now, while we can’t say that there are adequate improvements made to platform barriers, there are high expectations riding on the development of new technologies.”

An investigation by the transport ministry current to the end of March 2019 found that among the country’s 9,467 train stations, just 783 have doors installed on platforms. Additionally, it’s expected that all of the 3,588 stations nationally that see an average of more than 3,000 passengers a day will have works to install tactile blocks and make them barrier free completed by the end of fiscal 2020.
