Perspectives for lecture videos

This article presents an architecture for automated multi-perspective lecture recordings. The implementation switches between several video streams showing different perspectives in order to make the recording more vivid and to reduce the tunnel vision effect of single-perspective recordings. Automatic switching can be based on time intervals or, at a later stage of development, via simple recording rules.

Interaction support in large-scale lectures

1. INTERACTION SUPPORT IN LECTURES Interaction is an important aspect of lectures and can improve the learning success. However, meaningful “traditional” interaction based on hand-raising and discussion is at best difficult to achieve in large-scale lectures. Therefore, we have decided to design software to address this problem. We have determined the following interaction types that we regard as important for a well-balanced lecture: • asking the educator a question regarding the current content, such as “I do not understand this slide”,
