The complexity of modern technological systems has strongly increased the role and relevance of the few but crucial control tasks allocated to the human operator in the loop. This book develops a framework that gives guidelines and support to the analysi s of human-machine interaction, showing the types of simulations, analyses and domains of applications within this field. It focuses on the basic elements of human-machine system simulation and how models are actually developed in theoretical abstract terms and transformed into computerised, numerical simulations. Within the text the reader can find basic requirements and gu idelines for development of simulation models of human-machine interaction, a number of theories and numerical simulations of human behaviour, and a specific selection of sample cases showing the practical aspects of implementing the models. It is a valuable, practical overview of paradigms and simulation approaches that will be of great benefit to the engineer and designer of human-machine interfaces, and more broadly to anyone involved in the research or practice of human-machine interact ion.
