In this article, I report SlidesGo, a "virtual presentation room" software for a mobile head-mounted display. It allows a user to record a slide presentation video with an avatar in a virtual environment as well as to record head orientations during a presentation. and produce a heatmap to characterize the visual attention of the speaker during the recording. Instructional video productions using a mobile head-mounted display is far more time and cost efficient and give more insights into the teacher's non-verbal behaviour than those in a physical studio.Humancentered computingVirtual realityApplied computingElearning10.2312/egve.201912881-2
