Focus on Barriers, Not Disabilities
Some people see disabilities as barriers, but that is not the case. Example: Sarah has low vision and has a hard time reading some restaurant menus. Her low vision is not the barrier. It is the small print on the menus. When a restaurant gives Sarah a large print menu, she can read it and place her order independently and barrier-free.
To improve information, spaces and services, it is not necessary to know the details about the disability. Instead, focus on how to create spaces, interact with or serve individuals in a way that meets their needs. When in doubt, ask: How can I help you? There are many types of barriers that can be avoided with some planning.
