Originally published in 1989 this book is a distinctive work in the field of human-computer interaction (HCI). Cognitive ergonomics and HCI encompass a wide range of research and development activities in both academic and industrial environments and this book satisfies a clear need for the dissemination of the knowledge generated by work in progress or completed. The book provides detailed reports of a number of long-term research projects set within a framework for describing cognitive ergonomics activities and understanding their relationships. It reports in detail on substantial empirical investigations rather than being a summary of specific areas or theoretical speculations. The different contributions are integrated and have been rigorously edited within a framework provided by the editors and presented in the first chapter. Language: English
