Methods in affective engineering (or Kansei engineering) is one of the major areas of ergonomics (human factor engineering ). The study of integrating affective values in artefacts is not new at all. Already in the 18th century philosophers such as Baumgarten and Kant established the area of aesthetics. In addition to pure practical values, artefacts always also had an affective component. One example is jewellery found in excavations from the stone ages. The period of Renaissance is also a good example.
