A Small Knowledge-Based System for Selecting Interaction Styles

consists of a small knowledge-based system teaching and assisting designers of interactive applications in selecting appropriate interaction styles for a particular context of use. As any other tool for working with guidelines, five development milestones have been browsed. Guidelines for selecting interaction styles have been captured in a knowledge-base system as selections among an available set of possible interaction styles, a set of parameters characterizing the context of use, questions to provide the parameters’ values, and selection rules. Each rule selects a candidate interaction style candidate according to values assigned to parameters of the context of use according to a rule-based language, which basically consists of a first-order predicate logic formula. The values of these parameters are either stored or prompted to the designer through questions to form a final set of possible interaction styles.
