Avaliação de Usabilidade de uma Plataforma para Exploração de Dados de Segurança de Barraens: uma Consolidação de Resultados de Testes com Usuários e Avaliação Heurística
Abstract
Data-driven decision-making has gained paramount importance and has become indispensable to learning new knowledge and gaining insights in various contexts. Specifically, in critical and security contexts, interactive systems are imperative to support decision-making. However, for systems that enable data exploration, good usability is essential to facilitate effective data exploration for experts and laypeople. This study aimed to evaluate the usability of a system containing information regarding Brazilian dams, with a panel and an information filter, by consolidating the results obtained from user evaluations and a set of Human-Data Interaction heuristics proposed in the literature. The user evaluations involved 18 participants aged between 22 and 45 years, with previous knowledge about dam safety. Three specialists in Human-Computer Interaction performed the heuristic evaluation. The results from user evaluations and heuristic evaluation facilitated the analysis of the main problems encountered by users and their relationship with recently-proposed heuristics. User evaluations revealed the need for usability improvements related to the affordance of interactive map elements and information filters. The paper discusses the impact of the problems faced by users in the map-based dam data exploration platform and how the Human-Data Interaction heuristics aided the identification of different types of problems. These results provide crucial input for enhancing critical data exploration platforms and methodological reflections on the different contributions brought by different usability evaluation methods applied to Human-Data Interaction.
