Book excerpt: Advances in simulation technology have enabled an interesting amount of training and instruction to be conducted on training simulators instead of on real systems. However, experiences with the procurement and use of training simulators has not always been as successful, often owing to a lack of knowledge of didactics and of training programme development, and also to inadequate simulator specifications. The Handbook of Simulator-based Training represents the first comprehensive overview of the European state of the art in simulator-based training. It also comprises a well-founded and systematic approach to simulator-based training and the specification of simulator requirements. The multi-disciplinary research project described in this book combines the expertise of specialists in human factors, information systems, system design and engineering from 23 research and industrial organizations from five countries - France, Germany, the Netherlands, Spain, the UK. The authors have synthesized and documented the project results to ensure that this handbook provides not only many valuable guidelines, but more importantly a common frame of reference. It will be a key resource for the many specialists who are concerned with simulator-based training: researchers, engineers, and users; military training institutes and training system development departments; military staff responsible for the procurement of training devices and simulators; the simulator industry; the training research community; and the human factors and ergonomics community.
