From page 1...
... Since the interactions mnong the person, the equipment, the task, and the environment are complex, many researchers and engineers are concerned with the need for ergonomic models that describe the physical characteristics of people and their interactions with the task and equipment in the work environment. Such models should be representations of real systems designed to describe and predict their essential characteristics and performance.
From page 2...
... In order to develop a universal ergonomic model, comprehensive and accurate representations are required for such factors as physical size, visual field perception, reach capabilities, loadings on muscles and bones, and their responses and strength capabilities. Precise examination of anthropometric and biodynamic data is facilitated by modern data management techniques such as computer graphics and relational data bases for studying physical interactions.
From page 3...
... The following chapters describe the current status of development of anthropometric, biomechanical, and interface models, giving limitations and listing research needs specific to each. AN preaches to the development of integrated ergonomic models are discussed, and research recommendations are provided for further development of lower-level models.

This material may be derived from roughly machine-read images, and so is provided only to facilitate research.
