Abstract:

While user-centered design (UCD) is a commonly used process for designing mainstream hardware, software, and web interfaces; design for accessibility is relatively uncommon in education and practice. As a result, the scope of users and the situations in which they operate products is not as inclusive as it could be. Designing for accessibility does not require a whole new process. Accessible design techniques fit well into established UCD processes for designing a range of products, from a handheld device, to office software, to a government web site. By integrating accessibility into the design process, designers can efficiently create products that work effectively for more people in more situations.
