Everything you always Wanted to Know about HOS Micromodels but were Afraid to Ask

HOS-IV is a general purpose simulation tool for modeling human operators, systems, and the environment. To build a simulation, inputs to the model typically include descriptions of the system design, procedures for using the system, human operator characteristics, and a mission scenario. A set of operator micromodels are available to the HOS user to assist in the development of the simulation. These micromodels contain algorithms, based on experimental literature, that can predict the timing and accuracy of basic human cognitive, perceptual, and psychomotor actions. This paper describes the current set of human performance models available in HOS-IV as well as micromodels planned for development.
