In the design of information systems, the perspective is based upon the notion as proposed by Terry Winograd that information technology may be limited in its ability to improve human communication. "Expert behavior requires an exquisite sensitivity to context and an ability to know what to commit to. Computing machines, which are purposely designed to process symbols independent of their context, have no hope of becoming experts.". That sensitivity to context is thus more in the realm of the human than in that of the artificial.
