The last time I used interactive tools was when I used arrows and directions to find a classroom in the school, although the school’s road sign design was imperfect and inconvenient in my opinion. I think if it is designed for disabled people, there should be different wayfinding, for example, some disabled wheelchair self-service areas can be set up, and disabled people can store or borrow wheelchairs in this area. And set up a dedicated channel for the disabled to make it easier for them to pass. For blind design, there is Audio guidance (VoiceOver and Talkback compatible), Alerts before instructions, Route preview, and a Phone in the pocket. For those with hearing problems, you can set Text descriptions, Use of icons, and Route preview.
I also have a thought that I found that there are very few blind roads in the United States, and blind roads are road facilities that help blind people to walk. Blind roads are generally paved with two types of bricks, one is a bar-shaped guide brick, which guides the blind to move forward with confidence, which is called a blind road; To remind the blind. I think the United States can also add blind lanes to many roads, which is very useful for blind people.
