Masahiro Fujimoto, a 26-year-old esports player from Japan, is blind and often reliant on a human companion to assist him around the streets of Tokyo. However, he has recently put ChatGPT-4o to the test, in the hopes of the AI tool helping him walk to his destination without any external assistance. 

Masahiro, nicknamed 'Mashiro', is a professional 'Street Fighter' player, and he hopes that AI can be a promising tool for people with disabilities. To test out the limits of AI accessibility of OpenAI's ChatGPT, he used the app to give him directions to a stadium for a recent Para eSports meetup.

"I can't participate in an event like this without someone to rely on," Masahiro told AFP.  "Also, sometimes I just want to get around by myself without speaking to other people. So if I can use technology like ChatGPT to design my own special needs support, that would be great."

This year, the US firm OpenAI released GPT-4o, which understands voice, text and image commands in several languages. The generative gadget, along with others such as Google's Gemini, is part of a fast-growing field that experts say could make education, employment and everyday services more accessible.

Following the streets' tactile paving, Masahiro used his stick adorned with a small monkey mascot to find his way from the station. As he went, he spoke to GPT-4o like a friend, receiving its answers through an earpiece in one ear, leaving the other side free to listen out for cars.

Having asked for basic directions, he added: "In fact, I am blind, so could you give me further details for blind people?" "Of course," the bot replied. "You might notice an increase in crowd noise and the sound of activities as you get closer." The journey, 20 minutes for sighted people, took Mashiro around four times as long with several u-turns.

When it started to rain heavily, he requested help from his friend, who was partially sighted, to finish the journey. "Arrival!" finally shouted Mashiro, who has microphthalmos and has been blind since birth, using only sound to demolish his opponents on 'Street Fighter 6'.

"Enormous potential"

AI can cater to specific needs better than "one-size-fits-all" assistive products and technologies, said Youngjun Cho, an associate professor in computer science at University College London (UCL). "Its potential is enormous," said Cho, who also works at UCL's Global Disability Innovation Hub. "I envisage that this can empower many individuals and promote independence." People with hearing loss can, for example, use AI speech-to-text transcription, while chatbots can help format a resume for someone with learning disabilities.

Some tools for visually impaired people, such as Seeing AI, Envision AI and TapTapSee, describe phone camera images. Danish app Be My Eyes, where real-life volunteers help via live chat, is working with OpenAI to develop a "digital visual assistant".

But Masahide Ishiki, a Japanese expert in disability and digital accessibility, warned it could be "tricky" to catch mistakes from ChatGPT, which "replies so naturally". "The next objective (for generative AI) is to improve the accuracy of real-time visual recognition, to ultimately reach capabilities close to that of a human eye," said Ishiki, who is blind.

Marc Goblot of the Tech for Disability group also cautioned that AI is trained on "very mainstream datasets" which are "not representative of the full spectrum of people's perceptions and especially the margins".

Mashiro said ChatGPT's limited recognition of Japanese words and locations made his AI-assisted journey more challenging. Although the experiment was "a lot of fun", it would have been easier if ChatGPT was connected to a map tool, said the gamer, who travelled around Europe last year using Google Maps and help from those around him.

He has already decided on his next travel destination: Yakushima rainforest island in southern Japan. "I want to experience whatever happens when travelling somewhere like that," he said.
