Abstract
The Comprehensive Assistive Technology model was devised to describe the full social and engineering context of assistive technology devices, systems, applications, and provision. It is based on a detailed decomposition of the four attributes: Person, Context, Activities, and Assistive Technology. The paper commences will a brief discussion of the different representations of the model, including tree-diagrams, labelled attributes and tables and the use of engineering block diagrams to supplement some elements of the description. The main contribution of the paper is the presentation of four case studies of different applications of the model. These are the identification of accessibility barriers, the analysis and synthesis of assistive technology systems and the provision of a framework for identifying end-user requirements, providing assistive technology and assessing the associated outcomes. This case study involves the presentation of the novel concept of a personal assistive technology profile.
