Extra-Ordinary Human–Machine Interaction: What can be Learned from People with Disabilities?

Abstract: When specifying, designing and implementing technology for work, it is very important to consider the whole of the potential user group, and not to forget that this might include people with disabilities. Obvious reasons for this are demography, disabled people forming a significant and growing proportion of the workforce, and legal obligations caused by equal opportunities legislation. There are more subtle reasons, however, which link so-called ‘disabled people’ with the rest of the population. The paper notes that most people have some disabilities, sometimes temporarily due to accident, or permanently due to ageing and other processes. In addition it notes that even otherwise fully functioning people can be seriously handicapped by hostile environments, and a parallel is drawn between the human interface needs of disabled people operating in ordinary situations and able-bodied people operating in high workload and stress situations. The paper concludes by suggesting a research agenda for the field on the basis of these considerations.
