Otimização das interfaces da ferramenta LStyle: avaliação heurística e teste de usabilidade

Abstract

This work aimed to evaluate the usability of the LSTYLE tool, to help in the interaction of learning styles identification from the perspective of Nielsen's heuristic evaluation. To conduct the heuristic evaluation method, activities divided into four stages were considered: immersion, definition, ideation and prototyping. After having a general understanding of the tool's objective and the drafts of the system, the evaluation stage proceeded, based on the ten heuristics defined by Nielsen, obeying the presented usability criteria. For each violated heuristic, the evaluators suggested recommendations and solutions for improvement. From the recommendations, interface prototypes were developed considering the degree of severity attributed to each problem pointing, generating a new model of screens validated and consolidated by the heuristic. In the validation phase of the prototypes, an online questionnaire was used as a support tool, with the aim of generating a single score on an easy-to-understand scale and collecting user opinions regarding usability improvements, as well as scoring and classifying at a higher level. Quantitatively, user satisfaction and experience when performing all processes related to the LSTYLE learning identification tool.
