The Need for Integrated Human Performance Models 2000-01-2182

Large-scale simulations are making satisfactory progress in all areas except human performance. Graphics have produced human models that appear realistic (face validity), but do not always behave realistically. With a wealth of data about humans and human performance available, what keeps better data and models from being integrated into large-scale simulations? Do new requirements for verification, validation, and accreditation help or hinder the integration of the human component into large-scale simulation? Can those researching and modeling physical and cognitive issues work together to integrate their technologies? Can human performance models supplement or replace human-in-the-loop simulation, thereby reducing the cost and time required to develop a new system? The issues and technologies involved in developing and integrating human performance models are discussed.
