Accessibility is the concept of whether a product or service can be used by everyone—however they encounter it. Accessibility laws exist to aid people with disabilities, but designers should try to accommodate all potential users in many contexts of use anyway. To do so has firm benefits—notably better designs for all.
I am going to redesign the reading software for blind people. Blind people can not read, so all the articles in the reading software should have an audio version. It’s also challenging for blind people to find the play button, so I redesign the reading software.
Your sketch helped me a lot to understand your idea. I appreciate that you focus on the disabled and redesign the reading software for them. Since every people are disabled at a specific time, I feel that may also work for ordinary people.
