摘要：The ergonomic digital design and evaluation of man-machine system is the main application fields of virtual human technology. Because of the complexity of physical person and uncertainty of fatigue generation mechanism, it is difficult to express and evaluate the Virtual Human's fatigue state. This paper summarizes the characteristics of virtual human's fatigue evaluation, such as undeterminable, invisible, the constraint conditions can been used. Viewed from the strengths and weaknesses of preexisting models, metabolic energy expenditure model, dynamic muscle fatigue model and a model to assess fatigue at joint-level using the half-joint concept, this paper puts forward the future development trend that the combination of subjective and objective, diversification of the analyzable motion, real-time and visual expression.
