Abstract

Providing instructions via handheld prompters holds much promise for supporting independence for persons with cognitive disabilities. Because users of these tools are paired - caregivers who make scripts and a person with cognitive disabilities who uses them - designing such a system presents unique meta-design problems. The problems of changing content and configuration on a handheld computer, as needs and abilities change of the users with cognitive disabilities, produce a critical need for end-user programming tools. This paper describes the design and testing of the MAPS (Memory Aiding Prompting System) system, consisting of a handheld prompter and a multimedia editing tool for script creation, storage, and modification. The unique meta-design challenges of supporting end-user programming of context-responsive systems, and its broader implications, are presented.
