Design for usability
Nigel Bevan · International Conference on Human-Computer Interaction · 1999
Making the information society accessible to all requires both physical accessibility and cognitive accessibility (Bevan 1999c). Just as physical accessibility means providing the right physical interface, so cognitive accessibility means matching the functionality, terminology, information and interface to the needs of the individual user. The emphasis in systems design has traditionally been on building systems that meet specific functional requirements, without a sufficiently detailed understanding of the cognitive and physical capabilities and expectations of the intended users, or a clear view of the context in which the system will be used.
