Traditional blackboard-based lectures provide context on the sliding blackboards. Modern lectures incorporating video projectors typically do not provide this context. We describe a project that combines both approaches to provide context for "modern" lectures. We also discuss the benefits for educators and students. The software is sufficiently versatile to incorporate practically any software for content display.
In the transition from traditional teaching and learning to eLearning, this paper emphasizes smoothness. We claim that many virtual university and corporate university efforts worldwide try to showcase big leaps forward yet lack sustainability, suffer from in-vitro conditions, and leave behind the big mass of teachers (learning and teaching are used in the largest sense of these terms). The digital lecture hall (DLH) project accommodates traditional teaching methods right on the spot -making them 'digitally' available for computer assistance -but also reaches out to a large variety of computer assisted methods and to accompanying new organizational and business models. Apart from this smooth transition yet far reach, DLH has a second focus: the attempt to exploit venues which go well beyond class room size; as opposed to known "electronic classroom" efforts which are limited to some 15 to 30 local participants, audiences without size limits are supported in DLH, with the first implementation in operation offering a seating capacity of about 150.
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
