Assistive Technology for Visually Impaired and Blind People
Marion Hersh, Michael A Johnson
Springer Science & Business Media, May 12, 2010 - Technology & Engineering - 725 pages
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.
• 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.

The most remarkable thing about this book is that, even though I am visually impaired, I can't read it because it is a Google Book. No matter how much people talk about accessibility, it won't be a reality for those of us at the coalface until we can access material on a level playing field with our sighted colleagues. I have just spent 8 hours scanning this title from hard copy by hand, page by page, - and now I can begin to read the book.
