15 Korozi, M., Antona, M., Ntagianta, A., Leonidis, A., & Stephanidis, C. In Proceedings of the 10th Annual International Conference of Education, Research and Innovation. 2017 It is almost inevitable that during a course, students will get distracted either by internal or external stimuli. Introducing engaging activities into the main lecture and changing pedagogies within a class period has remarkable effects on students\’ concentration levels. This paper presents LECTORstudio, an authoring tool that enables educators to build the logic that guides the decision-making mechanisms of LECTOR, a framework capable of identifying inattentive behaviors and intervening to re-engage students to the educational process. LECTORstudio offers three simple and intuitive wizards that aim to guide educators through the sophisticated processes of (i) defining rules that signify inattention and (ii) describing the intervention strategies that should be applied under various educational circumstances. This work presents the functionality of the tool and the usability findings of a heuristic evaluation experiment conducted with UX experts. https://library.iated.org/view/KOROZI2017LEC
