USABILITY EVALUATION THROUGH EYE TRACKING: A SYSTEMATIC LITERATURE REVIEW

Abstract

Usability evaluation is traditionally carried out with techniques such as: questionnaires, thinking aloud, cognitive walkthroughs, and heuristics. The research works in this area are significant, they show advances including improvements to different techniques, new technologies, frameworks, prototypes, and approaches to work on usability. Eye tracking is a data collection technique used in visual research (e.g. reading patterns, mental fatigue) and recently in usability studies. In this research work, the result of the systematic review of the literature on the evaluation of the usability of software systems through eye-tracking techniques is presented. The review method allowed the identification of techniques, procedures, tools, and metrics used by researchers to evaluate usability. Similarly, the review allowed us to identify areas of opportunity to evaluate usability considering other usability metrics not yet explored.
