ABSTRACT
Digital simulations have been developed for automated assembly lines. The demand for digital simulations grew as the complexity of the systems to be simulated grew. Digital simulations for human factors testing have been around since the 1960s. This chapter describes many of the human factors tools used in the new design and testing processes. Developers use four types of tools in test and evaluation of the physical operator interface: mock-ups, physical human models, computer-aided engineering models, and simulators. The chapter explores specific tools in sufficient detail to enable a professional to judge their utility, as well as to acquaint those new to the field with these tools and how they are used. It discusses a different class of tools that are used to test the entire system performance. Embedded testing during normal product operation is conducted in some industries to improve performance-prediction accuracy. Embedded testing can provide the basis for continuous product improvement and improved training and user support functions.
