Development Background

Currently, it is basically not possible to use accompanying assistance by a helper for commuting to work, school, business activities, etc.
Therefore, social activities are restricted if the patient has difficulty getting around on his/her own.
There is also a shortage in the absolute number of accompanying aid employees.
It is not easy for the visually impaired to go out freely on their own, as there are many restrictions.

A word from an Eye Navi advisor
Mayumi Seo, a visually impaired person, is one of the collaborators who has continued to provide advice on the application since its development.
We have high expectations for this “extra help” when going out.
Seo said, “I hope it reaches many people. I hope it will be a source of comfort for those who are afraid to go outside and are in despair.” She also hopes that the book will be a source of comfort for those who are afraid to go outside and are in despair.
Commitment to the SDGs
Aiming to achieve this goal worldwide by 2030 under the slogan “No one will be left behind.
Our commitment to the Sustainable Development Goals (SDGs)
SDGs x Visually Impaired

03.Health and well-being for all
Ensure healthy living and promote the well-being of all people of all ages
We believe that Eye Navi can contribute to the Japanese government's goal of “3.6 Halve the number of people killed or injured in road traffic accidents worldwide by 2020. We believe that Eye Navi can contribute to this goal by providing information (color of people, cars, Braille blocks, and pedestrian signals, recognition of obstacles such as pedestrian crossings, and route guidance to destinations).
By utilizing Eye Navi, for example, the color of traffic signals can be recognized at crosswalks without sound signals, thereby increasing safety. It also eliminates the problem of no sound at night, even if they are installed.

10.Let's eliminate inequality among people and countries.
Reduce inequalities within and among countries
The Japanese government's stated goal “10.2 By 2030, promote the empowerment and social, economic, and political inclusion of all people regardless of age, gender, disability, race, ethnicity, origin, religion, economic status, or other circumstances. We believe that Eye Navi can contribute to this goal through the provision of information (color of people, cars, Braille blocks, and pedestrian signals, recognition of obstacles such as crosswalks, and route guidance to destinations).
In the development process of Eye Navi, we are taking the approach of “inclusive design” to improve the quality of service together with visually impaired people. Eye Navi may enable, for example, visually impaired people who could not go out without assistance to do so.

11.Creating a town where people can continue to live.
Achieve inclusive, safe, resilient, and sustainable cities and human settlements
The Japanese government's goal “11.7 By 2030, provide universal access to safe, inclusive, and accessible green spaces and public spaces for people, including women, children, the elderly, and people with disabilities. We believe that Eye Navi can contribute to this goal by providing information (color of people, cars, Braille blocks, and pedestrian signals, recognition of obstacles such as pedestrian crossings, and route guidance to destinations).
Eye Navi, for example, can be used to provide information and directions to the visually impaired in areas where Braille blocks have not been installed. Such measures for the disabled are not only beneficial to the disabled, but have the potential to become universal services that benefit many more people.

17.Achieve your goals in partnership!
Strengthen the means of implementation for sustainable development and revitalize the global partnership
The Japanese government's stated goal of “17.17 Encourage and promote effective public, public-private, and civil society partnerships based on a variety of partnership experiences and resource strategies. We believe that Eye Navi's efforts will contribute to this goal.
Eye Navi has been able to continue its research and development to this point thanks to support from the Ministry of Health, Labor and Welfare and other organizations. The project is made possible through collaboration with civic groups such as support groups for the visually impaired, academic institutions such as Tokyo Metropolitan University, and various partnerships with private companies.
