This book offers new data in the field of Systemic-Structural Activity Theory (SSAT). It includes unpublished data and new findings, which includes theoretical and practical applications, offering a unified framework not only for ergonomists and work psychologists, but also for economists who study productivity and the efficiency of human work.

Human-Computer Interaction (HCI) is an interdisciplinary field that has gained recognition as an important field in ergonomics. HCI draws on ideas and theoretical concepts from computer science, psychology, industrial design, and other fields. Human-Computer Interaction is no longer limited to trained software users. Today people interact with various devices such as mobile phones, tablets, and laptops. How can you make such interaction user friendly, even when user proficiency levels vary? This book explores methods for assessing the psychological complexity of computer-based tasks. It also presents methods of qualitative and quantitative analysis of exploratory activity during interaction with a computer.

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 of queuing theory, etc. The book will also present new data in the area of efficiency of labor force and its evaluation.
