Gaze-Based Monitoring in the Classroom
Michael Burch · 2023
In the roles of lecturers we have to present certain topics to students by means of Powerpoint slides, videos, animations, and the like. The content itself but also the presentation speed play crucial roles to make a lecture understandable for the students. Since each student has a different experience level, personal mood, or might be distracted by other scenarios the lecturers cannot keep track of all the individual students in a course but has to present the content more or less independently of the audience. In this paper we introduce work-in-progress that focuses on monitoring the students’ behavior in a course including the understanding of the presentation in terms of presentation speed. To reach this goal we make use of mobile eye tracking devices that permanently track the eye movements of the students paying visual attention to the lecturer’s slides. In the current state of the developed system we record two options, whether an individual student could follow and understand the slides or not while the summed up students’ feedback is reflected and displayed to the teacher in real-time, providing some kind of overview and avoiding asking questions permanently about the understanding of the slides’ contents. Finally, we will discuss challenges and limitations of our gaze-based monitoring system.
