Definition: According to the Penguin Dictionary of Psychology (Reber & Reber, 2001, p. 248), ergonomics is "the science of the 'fit' between jobs and persons, the study of the relationship between an individual's anatomy, physiology and psychology and the demands of particular forms of work".
How can such features be used to improve productivity?
I would rather say: How do such features improve productivity?
Answer: By reducing or eliminating superfluous effort or even noxious effects on health while going after work tasks. In practice, according to Sonntag (2001, p. 568), this can be achieved through the "identification of regulation requirements and cognitive demands" as well as the "identification of regulation obstacles in industrial work" (ibid.). Many theoretical assumptions behind such an approach are outlined by Leitner and Resch (2005) as well as by Hacker (2003). In short, regulation obstacles refers to the psychic regulation of work activity. Even more details can be found in Rau (2004).
