Equal accessibility to public places and services is now required by law in many countries. In the case of the vision-impaired, it is often the use of specialised technology which can provide them with a fuller enjoyment of all the facilities of society from large scale meetings and public entertainments to the more personal level of reading a book or making music. In this volume the engineering and design principles and techniques used in assistive technology for blind and vision-impaired people are explained. Features:• instruction in the physiology of the human visual system and methods of measuring visual ability;• explanation of many devices designed for every-day living in terms of generic electrical engineering principles;• sections of practical projects and investigations which will give the reader ideas for student work and for self teaching;• contributions by authors of international repute from divers fields which co-operate under the banner of assistive technology, among them: artificial vision systems; psychology, haptics, electrical engineering, design and visual physiology. Assistive Technology for Vision-impaired and Blind People is an an effective means of maintaining the currency of knowledge for engineers and health workers working to provide devices and/or services for people with sight loss and an excellent source of reference for students working in assistive technology and rehabilitation. | Assistive Technology for Visually Impaired and Blind People by Marion Hersh, Hardcover | Indigo Chapters
