HoloBoard: a Large-format Immersive Teaching Board based on pseudo HoloGraphics
This addresses the need for more engaging and effective teaching tools in educational settings, though it appears incremental as it builds on existing immersive display technologies.
The paper tackles the problem of enhancing lecture-based classes by introducing HoloBoard, a large-format pseudo-holographic display system, which resulted in slightly better learning outcomes and significantly higher student engagement compared to normal classes.
In this paper, we present HoloBoard, an interactive large-format pseudo-holographic display system for lecture-based classes. With its unique properties of immersive visual display and transparent screen, we designed and implemented a rich set of novel interaction techniques like immersive presentation, role-play, and lecturing behind the scene that is potentially valuable for lecturing in class. We conducted a controlled experimental study to compare a HoloBoard class with a normal class by measuring students' learning outcomes and three dimensions of engagement (i.e., behavioral, emotional, and cognitive engagement). We used pre-/post- knowledge tests and multimodal learning analytics to measure students' learning outcomes and learning experiences. Results indicated that the lecture-based class utilizing HoloBoard lead to slightly better learning outcomes and a significantly higher level of student engagement. Given the results, we discussed the impact of HoloBoard as an immersive media in the classroom setting and suggest several design implications for deploying HoloBoard in immersive teaching practices.
