Usabilidade de ícones em Ambientes Virtuais de Aprendizagem: uma análise pela ótica da neurociência e da experiência do usuário

Abstract

This study presents the analysis of the usability of icons in learning management systems, from the perspective of neuroscience and user experience. The research was based on Design Science Research and, therefore, was based on systematic reviews of the literature on all the topics covered, obeying the rigor of the proposed methodology. It was evaluated through usability tests, such as heuristic evaluation and cooperative evaluation, the user's cognitive load when using the Fiocruz Learning Management System (LMS), and its interaction with the interface iconography. The contribution of neuroscience to this research occurred during the performance of the cooperative evaluation with the use of the eye tracker and functional near-infrared spectroscopy (fNIRS) to measure the user's cognitive load, such as his attention and engagement, during the interaction with the interface and its iconography. As a result, there is the proposition of a set of heuristics HEAD, original and unprecedented, for learning management systems with a focus on iconography, as an artifact for the development of interfaces with more representative icons, which demand less cognitive effort from the user for their understanding, resulting in distance education platforms more intuitive and efficient.
