| Abstract: | Usability evaluation is crucial for assessing systems and applications effectiveness and user-friendliness. Traditional methods, such as Cognitive Walkthrough and Usability Smells, often fail to capture emotional dimensions of user experiences. The emergence of facial emotion analysis offers a novel approach to addressing this limitation by providing a more comprehensive understanding of user interactions. This paper introduces "The Emotionality Tool", an innovative solution that integrates facial emotion analysis into traditional usability evaluation methodologies. The tool features a user-friendly interface for conducting tests, capturing, and analyzing facial emotions, enabling expert evaluators to gain deeper insights into the emotional aspects of user interactions. Case studies demonstrate the tool's effectiveness in uncovering critical usability issues and its potential applications in refining interface designs. "The Emotionality Tool" represents a valuable resource for incorporating emotional metrics into usability evaluation, enriching methodologies and advancing the field of user experience research.
