Revision with unchanged content. In the US alone, over four and a half
million people have cognitive disabilities. Except for deficiencies of
mnemonic and executive capabilities, many of them have the potential to
live a more independent life. In this book, the author describes a
design approach and an example system aimed at providing support to
those missing abilities in a socio-technical environment. The system,
MAPS, consists of two technical components: a script design tool that
allows a caregiver to create, store, edit and reuse scripts of
multimedia prompts to guide users thru tasks, and a PDA-based prompter
that plays those scripts for persons with cognitive disabilities. The
process of technology adoption was also studied as the MAPS system was
put in use doing real-life tasks in home, shopping, and employment
environments. By extending human-computer interaction (HCI) frameworks,
theories, and perspectives, this research shows new ways of using
traditional HCI in the design and use of prompting systems. More
importantly, this study presents a set of heuristics to aid in the
general design of assistive technology with an aim of preventing
technology abandonment.
