Understanding Decision Requirements for Selection of Assistive Technology

Abstract

Individual consumers and clinicians have difficulty selecting computer access solutions and keeping up with the advances in access technologies. To design a decision support tool for consumers and clinicians, a thorough understanding of the decision-making process is important. A cognitive tasks analysis was conducted to reveal the underlying cognitive processes and decision requirements, and identify potential decision aids. The analysis used semi-structured interviews for consumers, and clinical observations followed by retrospective interviews for clinicians. Based on the identified decision needs and information needs, design implications are provided.
