Understanding User Centred Design (UCD) for People with Special Needs

"User centred design" (UCD) has become a central, largely unquestioned, tenet of good practice for the design of interactive systems. With the increasing recognition of the importance of special needs in influencing design, UCD needs to be re-examined, in particular to be clear about the difference between using its methods, which may not suit special needs, and achieving its objectives. This paper introduces a simple two-category classification of special needs, to which UCD applies very differently and which are heavily affected by developments in technology; in other words, the role of UCD, particularly with respect to special needs, will continue to change and demand close scrutiny.
