Snigdha Das, Sandip Chakraborty, Bivas Mitra · 2021
Educational systems have witnessed a rapid transformation from the traditional physical classroom to the online teaching mode due to the COVID-19 pandemic. This sudden shift throws two significant questions to the educational policymakers and system designers. (1) How can an instructor improve the teaching performance over an online teaching platform? (2) How does the instructor understand the students’ learning pace? For answering these questions, we propose a platform in this paper that analyzes the real-time presentation video and the facial video feeds from the instructor as well as the students to explore the visual engagement of the student towards the lecture contents. However, this is challenging as the students may get involved in various multitasking instances, such as taking notes or browsing relevant reading materials. The crux of this paper is to understand a few real-time opportunistic moments when the students should visually focus on the presentation content if they are engaged and been able to follow the lecture. We investigate these instances and analyze the visual engagement of the students from their eye gaze and gaze gestures in real-time during those instances to assess their engagement during an online class. Our system achieves 71% (standard deviation accuracy for all over the scenarios in students’ involvement detection during the virtual classroom.
