Addressing a wide range of human factors and ergonomics principles, this book emphasizes concept and systems thinking and how the allocation of function between the human and the machine has changed as a result of technological advances. Comprehensive in breadth and depth of coverage, the text focuses on conventional machines and workspace design, artificial life, environmental design, work in outer space, and stress and work performance. A separate chapter on accident analysis and prevention includes an updated review of the effectiveness of safety programs. The authors give readers the tools to creatively apply the concepts to new problems and photographs illustrate real systems in operation.
