Designers rarely design to exclude, but sometimes it just happens. Creating digital materials that are usable and accessible means many more people have access. Here is a book chapter that introduces readers to the ways people with disability use technology. It includes specific steps you can take and highlights the benefits of accessible design. Testing by people with disability is informative and should be included in the design process. As always, planning for accessibility from the start is always more cost-effective than fixing problems later. The title of the chapter is, “Designing for Inclusion: Ensuring Accessibility for People with Disabilities”. You will need institutional access to SpringerLink for a free read.
