The book presents the case that cognitive science should turn its attention to developing theories of human cognition that cover the full range of human perceptual, cognitive, and action phenomena. Cognitive science has now produced a massive number of high-quality regularities with many microtheories that reveal important mechanisms. The need for(More)
In this paper, we describe why designers need to look beyond the twin aims of designing for the 'typical' user and designing "prostheses". Making accessible interfaces for older people is a unique but many-faceted challenge. Effective applications and interface design needs to address the dynamic diversity of the human species. We introduce a new design(More)
Contemporary technology offers many benefits to older people, but these are often rendered inaccessible through poor software design. As the Internet increasingly becomes a source of information and services it is vital to ensure that older people can access these resources. As part of project funded by the UK government, a multidisciplinary team set out to(More)
Although " User Centred " , " Participatory " , and other similar design approaches have proved to be very valuable for mainstream design, their principles are more difficult to apply successfully when the user group contains, or is composed of, older and/or disabled users. In the field of design for older and disabled people, the " Universal Design " , "(More)
This paper discusses the use of theatrical techniques to communicate to designers the user requirements for IT interfaces-particularly those of " extreme users " such as older people. The methodology and processes of producing such material in a video form are described, together with the strengths and weaknesses of this approach. The paper concludes by(More)
Memory problems are often associated with the ageing process and they are one of the commonest effects of brain injury. Electronic memory aids have been successfully used as a compensatory approach to provide reminders to individuals with prospective memory problems. This paper describes the usability issues surrounding the development of a new memory aid(More)
