Every complex human-machine system includes a computer as a critically important means of work. However, an operator's interaction with a computerized system cannot be reduced to only performing computer-based tasks. Today human-computer interaction (HCI) is not limited to trained software users. People of all ages use all different kinds of gadget

Activity theory is an interdisciplinary approach to human sciences that originates in the cultural-historical psychology school, initiated by Vygotsky, Leont'ev, and Luria. It takes the object-oriented, artifact-mediated collective activity system as its unit of analysis, thus bridging the gulf between the individual subject and the societal structure. This 1999 volume includes 26 chapters on activity theory by authors from ten countries. In Part I of the book, central theoretical issues are discussed from different points of view. Some topics addressed in this part are epistemology, methodology, and the relationship between biological and cultural factors. Part II is devoted to the acquisition and development of language. This part includes a chapter that analyzes writing activity in Japanese classrooms, and a case study of literacy skills of a man with cerebral palsy. Part III contains chapters on play, learning, and education, and Part IV addresses the meaning of technology and the development of work activities. The final part covers issues of therapy and addiction.

Through the use of new analytical tools, this book presents a dynamic, sociocultural view of behavioural regulation in learning contexts.

This book offers analytical methods for studying human work in ergonomics and psychology that are similar to ones utilized by the engineering sciences. SSAT offers not only new qualitative but also formalized and quantitative methods of analysis. This book will describe quantitative methods of task complexity and reliability assessment, application

This book is a collection about cultural-historical activity theory as it has been developed and applied by Yrjö Engeström. The work of Engeström is both rooted in the legacy of Vygotsky and Leont'ev and focuses on current research concerns that are related to learning and development in work practices. His publications cross various disciplines and develop intermediate theoretical tools to deal with empirical questions. In this volume, Engeström's work is used as a springboard to reflect on the question of the use, appropriation, and further development of the classic heritage within activity theory. The book is structured as a discussion among senior scholars, including Y. Engeström himself. The work of the authors pushes on classical activity theory to address pressing issues and critical contradictions in local practices and larger social systems.

This book presents new data in Applied Activity Theory (AAT) and Systemic-Structural Activity Theory (SSAT), that can be used in the study of human performance. The SSAT is the high-level generality theory that offers standardized principles of the analyses of human activity. These principles can be utilized in theoretical and applied studies. This multi-contributed book offers a selection of works that will provide a holistic picture of the field. The new data can be utilized for the study of extremely complex human-machine and human-computer interaction systems, and for evaluation of efficiency, complexity, and reliability of such systems at the design stage. Features Shows examples of self-regulative models of various cognitive processes Illustrates a method of study of production process in the construction industry Includes topics on learning, training, and management Covers a new method of computer based automated support of decision making under risk and uncertainty Presents a new method of evaluation of probabilistic structure of tasks, and the method of assessing reliability of human performance

Human Computer Interaction (HCI) is no longer limited to trained software users. Today people interact with various devices such as mobile phones, tablets, and laptops. How can such interaction be made more user friendly, even when user proficiency levels vary? This book explores methods for assessing the psychological complexity of compute
