Description

<p>Although Human Factors and Ergonomics (HFE) is regarded an academic discipline to understand interaction between human and system, a theory for understanding the interaction has not yet been established. For the aim of understanding interaction in terms of task demand and performance, we examined concepts developed in related disciplines, and tried to integrate them into a HFE framework. Key concepts of this idea are task demand, performance, demand control, balancing between demand and performance and its appraisal, range of balanced zone and its expansion, and resource and resource management. This framework provides a comprehensive view of human activities and a systematic understanding of various mental states such as fatigue, workload, emotion and motivation, and mental stress.</p>
