Allowing tutor to understand if students are engaging. Students observed by cameras, where they sit, how they are sitting, and are asked to complete questions at several stages through lecture to capture levels of attention. Tutor can see how levels of attention change spatially and over time. Understand that there are factors other than tutor and materials that affect students, eg other students causing distraction ripples. Common motion patterns, ie students moving at the same time, indicate similar reactions to material and tutor instructions. Periods of activity and inactivity can be tracked and compared to what is going on in the room at the time.
Can observe moments of settling as students are engaging and listening. Aim is to collect more data and improve motion detection and try to find a correlation between what is observed and what is going on in the room.
