Some of the common methods used in this field are ethnographic analysis, meta-analysis, human performance modelling, kansei method, focus groups and macroergonomic analysis of structure. This field combines the concepts of various other fields such as anthropometry, biomechanics, psychology, visual design, user interface design and engineering. The topics covered in this extensive book deal with the core aspects of ergonomics. Also included herein is a detailed explanation of the various concepts and applications related to this field.
