During the different educative processes in the high school or university, a student feels different emotions. For instance, physiological stress has mostly experimented during exam periods, when there is academic overload, in new topics or learning too focused on memorization. Additionally, the stress has been associated with chronic diseases (e.g., heart diseases, faults in the immune system, anxiety or headaches). In line with these notions, in this paper, we introduce the idea of measuring emotions in order to empower the educative processes by providing relevant emotional information of all stakeholders involved in the educational task. This kind of information is highly useful for analyzing new educational methodologies or for evaluating the current educational approaches (educational institutions), and for students because it will allow a possible optimization in their teaching-learning process. Regarding the results, we present a preliminary experiment to evaluate the emotion detector, which obtained an accuracy of 79.17%.
