This book constitutes the refereed proceedings of the International Conference on Ergonomics and Health Aspects of Work with Computers, EHAWC 2007, held in Beijing, China in July 2007 in the framework of the 12th International Conference on Human-Computer Interaction, HCII 2007 with 8 other thematically similar conferences. It covers health and well being in the working environment as well as ergonomics and design.

The 12th International Conference on Human-Computer Interaction, HCI Inter- tional 2007, was held in Beijing, P.R. China, 22-27 July 2007, jointly with the Symposium on Human Interface (Japan) 2007, the 7th International Conference on Engineering Psychology and Cognitive Ergonomics, the 4th International Conference on Universal Access in Human-Computer Interaction, the 2nd International Conf- ence on Virtual Reality, the 2nd International Conference on Usability and Inter- tionalization, the 2nd International Conference on Online Communities and Social Computing, the 3rd International Conference on Augmented Cognition, and the 1st International Conference on Digital Human Modeling. A total of 3403 individuals from academia, research institutes, industry and governmental agencies from 76 countries submitted contributions, and 1681 papers, judged to be of high scientific quality, were included in the program. These papers address the latest research and development efforts and highlight the human aspects of design and use of computing systems. The papers accepted for presentation th- oughly cover the entire field of Human-Computer Interaction, addressing major - vances in knowledge and effective use of computers in a variety of application areas. This volume, edited by Don Harris, contains papers in the thematic area of En- neering Psychology and Cognitive Ergonomics, addressing the following major topics: • Cognitive and Affective Issues in User Interface Design • Cognitive Workload and Human Performance • Cognitive Modeling and Measuring • Safety Critical Applications and Systems

This book's primary objective is to provide a comprehensive coverage of ergonomics in overall work system analysis and design. It provides a summary of the historical development of macroergonomics. It explains how an understanding of macroergonomics can lead to improvements in such things as reducing work-related lost time accidents; and describes the methods and tools used in work system analysis and design. Throughout, the integrating theme is that the full potential of an organization--in terms of productivity, safety, health, and Quality of Work Life (QWL)--can't be met unless the overall work system is designed to conform with the characteristics of its technology, personnel subsystem, and the external environment upon which it depends for its survival and success. Using a sociotechnical systems approach, this text discusses the application of macroergonomics to training system development, hazard management, technology transfer, large scale organizational change projects, office and factory automation, community planning and development, and job design. For each of these applications, actual case examples will be included. The book will appeal to teachers of introductory human factors/ergonomics courses as a supplemental text or as the primary text for a course fully devoted to macroergonomics. In addition, it should also appeal to practicing ergonomists internationally as a must add to their personal professional libraries.
