APPLICATIONS OF FUZZY-BASED LINGUISTIC PATTERNS FOR THE ASSESSMENT OFCOMPUTER SCREEN DESIGN QUALITY

The main objective of this study was to develop a modeling framework w hich would unify different aspects of computer screen design and resul t in a quantitative criterion for an optimized computer screen format. The fuzzy set-based linguistic design patterns were utilized as a too l to build this model. The linguistic patterns are based on categories of expressions related closely to natural language and truth values, which are close to a human designer's intuition. The proposed framewor k is capable of assessing the quality of computer screen design based on existing knowledge in human-computer interface domain using the fuz zy-based linguistic pattern approach. Exemplary patterns for an optima l screen density, information grouping, and some aspects of screen lay out are presented, along with a sequence of calculations based on the exemplary screen format. This study showed that it is possible to achi eve a rational and relatively easy to interpret assessment of differen t screen designs in the form of the degrees of truth. Such an evaluati on criterion reflects the compatibility of a given screen design with the optimal one based on the current knowledge in the field. It is bel ieved that the proposed methodological framework for computer screen d esign should significantly augment the efforts of human designers.
