  Human-Computer Interaction with the traditional User Interface is done using
a specified in advance script dialog menu, mainly based on human intellect and
unproductive use of navigation. This approach does not lead to making
qualitative decision in control systems, where the situations and processes
cannot be structured in advance. Any dynamic changes in the controlled business
process (as example, in organizational unit of the information fuzzy control
system) make it necessary to modify the script dialogue in User Interface. This
circumstance leads to a redesign of the components of the User Interface and of
the entire control system. In the Intelligent User Interface, where the dialog
situations are unknown in advance, fuzzy structured and artificial intelligence
is crucial, the redesign described above is impossible. To solve this and other
problems, we propose the data, information and knowledge based technology of
Smart/ Intelligent User Interface (IUI) design, which interacts with users and
systems in natural and other languages, utilizing the principles of Situational
Control and Fuzzy Logic theories, Artificial Intelligence, Linguistics,
Knowledge Base technologies and others. The proposed technology of IUI design
is defined by multi-agents of Situational Control and of data, information and
knowledge, modelling of Fuzzy Logic Inference, Generalization, Representation
and Explanation of knowledge, Planning and Decision-making, Dialog Control,
Reasoning and Systems Thinking, Fuzzy Control of organizational unit in
real-time, fuzzy conditions, heterogeneous domains, and multi-lingual
communication under uncertainty and in Fuzzy Environment.
