Assistive Technology for Visually Impaired and Blind People

Equal accessibility to public places and services is now required by law in many countries. For the vision-impaired, specialised technology often can provide a fuller enjoyment of the facilities of society, from large scale meetings and public entertainments to reading a book or making music. This volume explores the engineering and design principles and techniques used in assistive technology for blind and vision-impaired people. This book maintains the currency of knowledge for engineers and health workers who develop devices and services for people with sight loss, and is an excellent source of reference for students of assistive technology and rehabilitation.

Dr Hersh is currently a senior Lecturer in the Department of Electronics and Electrical Engineering, University of Glasgow. She was previously a lecturer in this Department. She has also held posts as a Post-doctoral Research Fellow at the Universities of Sussex and Strathclyde. She has now been researching in the area of assistive technology for about 12 years.

Her current research interests fall into four main areas:

Assistive technology, particularly for people with sensory impairments.

Ethics and Social Responsibility Issues in Science and Engineering.

Good design practice, including the principles of sustainable and universal design, end user involvement and human centred design approaches.

The research process.

She is continuing to run the successful CVHI conference series Conference and Workshop on Assistive Technologies for People with Vision and Hearing Impairments, which she initiated with Prof Mike Johnson of the University of Strathclyde. Funding for the first three events was obtained from the EC High-Level Scientific Conferences Programme and the current funding for three further events, of which one has already taken place. Distinctive features of this conference series include the support given to young researchers and the conference ambience which encourages networking.

Current research projects in the area of assistive technology include the development of a communication and interface device for deafblind people, distance learning for people with mobility impairments with colleagues from Germany, Hungary and Romania and travel support technology for blind people with colleagues from France. Having been a workaholic for most of her life, Dr Hersh has recently become aware of the importance of making leisure activities accessible. Research carried out for the book has confirmed the lack of technology to support the involvement of blind people in sport and other leisure activities. Research projects in this area include technological support for learning swimming and cycling in quiet areas for blind people.

Dr Hersh recently published Mathematical Modelling for Sustainable Development with Springer Verlag (2006). It is organised into three parts, each of which considers the application of a particular type of mathematical or computing technique to problems in sustainable development. Particular features of the book include the large number of examples of the application of the techniques to problems in sustainable development, the detailed case studies, for instance of the application of systems theory to sustainable waste management and the introduction of fuzzy set techniques she developed. She has worked on applications of these techniques in collaboration with colleagues from Germany and Romania.

Dr Hershs awareness of the importance of interdisciplinarity for successful research in assistive technology has led her to an examination of the research process and publications on interdisciplinary work and research cultures with colleagues from Wales.

Dr Hersh is a Member of the Institute of Mathematics and its Applications, the Institution of Engineering and Technology (UK) and the Institute of Electronic and Electrical Engineers (USA).

Professor Johnsons academic career has concentrated on control engineering, theory and applications. He has significant industrial control applications and research experience. He is the author and co-author of books and technical papers on power generation, wastewater control, power transmission, and control benchmarking. He has had a number of student projects in the area of assistive technology and has successfully trained over 40 engineers to PhD level in last 20 years. He is joint Editor to Springer-Verlag-London monograph series Advances in Industrial Control and to the Springer-Verlag-London Advanced Textbooks in Control and Signal Processing series. He was an Associate Editor for Automatica in the years 1985-2002.

His interest in Assistive Technology came through undergraduate teaching commitments which included student group study dissertations at 2^nd Year level and assorted project supervision at Masters and undergraduate level. These were used to explore some EEE aspects of assistive devices for the hearing impaired. Subsequent collaboration with Dr. Hersh at the University of Glasgow led to a set of targeted activities in this area. These include a new course module, a new conference series and some research projects.

Professor Johnson retired from academic life in 2002 and was made an Emeritus Professor of the University of Strathclyde in 2003. Emeritus Professor Johnson is a member of Deafblind, UK and the British Retinitis Pigmentosa Society.
