This volume in The SAGE Reference Series on Disability explores issues involving assistive technology engineering and science. It is one of eight volumes in the cross-disciplinary and issues-based series, which incorporates links from varied fields making up Disability Studies as volumes examine topics central to the lives of individuals with disabilities and their families. With a balance of history, theory, research, and application, specialists set out the findings and implications of research and practice for others whose current or future work involves the care and/or study of those with disabilities, as well as for the disabled themselves. The presentational style (concise and engaging) emphasizes accessibility. Taken individually, each volume sets out the fundamentals of the topic it addresses, accompanied by compiled data and statistics, recommended further readings, a guide to organizations and associations, and other annotated resources, thus providing the ideal introductory platform and gateway for further study. Taken together, the series represents both a survey of major disability issues and a guide to new directions and trends and contemporary resources in the field as a whole.
