INTELLIGENT INTERFACES.

The exchange of data and control information between man and machine or between various modules in a complex manufacturing system can either be done through standardized or specially defined interfaces. For either of the two ways applied, all data channels should be well defined and rigorously implemented otherwise proper functional operation cannot be secured. In the present practice this is the most formidable obstacle when creating flexible control systems. This paper surveys four approaches to establish more flexible, more intelligent interfaces. The self-adaptive interface is independent from the user and from the system as well. The extended man-machine interface is based on the roles of human communication.
