With an emphasis on usability, over two-dozen contributions from international researchers discuss assistive technologies for persons with disabilities and the elderly. The volume is divided into four sections: human-machine interface; context awareness; mobility and assistive robotics; and computer accessibility. Sample topics include reducing costs of the design of an adapted living area; using laser telemetry to improve the mobility of blind people; and evaluating the accessibility of Web services. The volume lacks a subject index. Annotation ©2005 Book News, Inc., Portland, OR
