Assistive Technology for Visually Impaired and Blind People

Langbeschreibung
Equal accessibility to public places and services is now required by law in many countries. It is often the use of specialised technology which can provide the vision-impaired with a fuller enjoyment of all the facilities of society. 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.
Hauptbeschreibung
Equal accessibility to public places and services is now required by law in many countries. For the vision-impaired, specialised technology can provide a fuller enjoyment of the facilities of society, from meetings and public entertainments to reading a book or making music. This volume explores engineering and design principles and techniques used in assistive technology for blind and vision-impaired people. Features include instruction in the physiology of the human visual system and methods of measuring visual ability; explanation of electrical engineering principles of devices designed for everyday living; practical projects and investigations which inspire student work and self teaching; contributions by renowned authors from diverse fields under the banner of assistive technology: artificial vision, psychology, haptics, electrical engineering, design and visual physiology. This book is a source of reference for professionals who develop devices and services for people with sight loss, and for students working in assistive technology and rehabilitation.
