Sound-Based Assistive Technology

This book presents a technology to help speech-, hearing- and sight-impaired people. It explains how they will benefit from an enhancement in their ability to recognize and produce speech or to detect sounds in their surroundings. Additionally, it is considered how sound-based assistive technology might be applied to the areas of speech recognition, speech synthesis, environmental recognition, virtual reality and robots. The primary focus of this book is to provide an understanding of both the methodology and basic concepts of assistive technology rather than listing the variety of assistive devices developed. This book presents a number of different topics which are sufficiently independent from one another that the reader may begin at any chapter without lacking background information. Much of the research quoted in this book was conducted in the author's laboratories at Hokkaido University and University of Tokyo. This book offers the reader a better understanding of a number ofunsolved problems that still persist in the field of sound-based assistive technology.

Deals with information communication technology contributing to supporting the aging society as well as the sensory and communication disabled Provides new insights into the human senses and the brain functions concerning communication and environment recognition Includes a lot of hints to produce the new VR (Virtual Reality) technologies and communication robots Includes supplementary material: sn.pub/extras

Tohru Ifukube received the MS and D.Eng degrees in electronics from Hokkaido University in 1971 and 1977, respectively. He joined the laboratory of Medical Electronics, Research Institute of Applied Electricity, Hokkaido University, in 1971.He was also a visiting Associate Professor at Stanford University, CA in 1984.

He was a professor of the Medical Electronics Laboratory and Sensory Information Laboratory at the Research Institute for Electronic Science, Hokkaido University from 1989 to 2002.

He was a professor at the Research Center for Advanced Science and Technology, University of Tokyo until 2010. He is a professor of Hokkaido University of Science and also a research fellow at Institute of Gerontology at the University of Tokyo. He is a professor emeritus of both Hokkaido University and the University of Tokyo. His research interests include the analysis of the human sensory functions and the design of sensory aid devices. Some of these devices have been used for the blind as well as the deaf, and also have been applied to virtual reality and robotic systems.

Fellow: Institute of Electronics, Information, and Communication (2002), Fellow (2011) and President (2012-2013): Virtual Reality Society of Japan, Awards: Established Lifetime Achievement Award of the Robotics Society of Japan (2010), Nakayama Award Grand Prize (for Human Science, 2010), Masters honoring of sound (for Earthquake Early Warning Chime, 2012), Hokkaido News Paper Prize (for Assistive Technology, 2014) .

He is research leader and selection committee of many national project such as a Program Officer Design of Technology and systems for super-aged society of JST (Japan Science and Technology Agency), a selection committee chairman of Information barrier-free project (Ministry of Internal Affairs and Communications) and a selection committee of Aids for hearing and seeing (Ministry of Health, Labour and Welfare).

Klappentext

This book "Sound-based Assistive Technology" explains a technology to help speech-, hearing- and sight-impaired people. They might benefit in some way from an enhancement in their ability to recognize and produce speech or to detect sounds in their surroundings. Additionally, it is considered how sound-based assistive technology might be applied to the areas of speech recognition, speech synthesis, environmental recognition, virtual reality and robots. It is the primary focus of this book to provide an understanding of both the methodology and basic concepts of assistive technology rather than listing the variety of assistive devices developed in Japan or other countries. Although this book presents a number of different topics, they are sufficiently independent from one another that the reader may begin at any chapter without experiencing confusion. It should be acknowledged that much of the research quoted in this book was conducted in the author's laboratories both at Hokkaido University and the University of Tokyo. This book offers the reader a better understanding of the number of unsolved problems that still persist in the field of sound-based assistive technology.
