Abstract—Abstract—Usability Engineering is one of the most exciting and evolving areas of the research in the domain of human-computer interaction (HCI) and an integral part of HCI. Significant investigation has been conducted on the associations and conflicts between quality aspects but not much of work has been carried out on the identification of conflicts among usability requirement attributes separately. In this paper we have proposed a framework to examine the usability attributes trade-offs, involved in software development. It identifies the conflicts among usability requirement attributes and quantifies these conflicts using fuzzy methodology. The use of fuzzy modeling to deal with vagueness and contradictions in usability factors and its sub-factors makes this study a valuable contribution on this subject.
Index Terms—Index Terms—Human computer Interaction (HCI), usability requirement (URs), conflict identification, fuzzy logic.
