Some Limitations to Ergonomic Design

  • J. Moraal
Part of the NATO Conference Series book series (NATOCS, volume 25)


In coping with his environment man has to perform numerous and diversified tasks, be it at home, in his work or in recreational or social acitivities. Tasks vary from very simple to highly complex, in sort and amount of required experience and skills, like precision, speed and strength, and in whether or not tools or aids are used to enlarge human capabilities. These tools and aids - usually called “machines” - also vary from simple to highly complex, e.g. a spoon versus a space capsule. Tasks have to be performed efficiently, comfortably and safely, at least in the opinion of the ergonomist or human engineer. In order to meet these criteria, it is not very adequate to merely tell people how to behave because, although they may be well motivated, it mostly is not known what exactly efficient and safe behaviour is, how it should be defined and what kind of capabilities are required to behave accordingly.
