TL;DR: In this paper, the authors argue that current technologies and implementations do not adequately support the key concepts of communication and community that many practitioners believe to be important, particularly if modern pedagogies such as constructivism are to be supported.

TL;DR: This paper will look at not only why spatial audio can greatly improve virtual experiences, but also some of the new technologies that have become available in recent times which make the implementation of spatial audio far easier and of a higher quality than ever before.

TL;DR: This work proposes a tracking-by-detection algorithm to track the movements of meeting participants from an overhead camera, combining motion detection using adaptive accumulated frame differencing (AAFD) with Shi-Tomasi corner detection and shows that this approach achieves excellent performance in terms of multiple object tracking accuracy (MOTA) metrics.

TL;DR: In this article, the authors present an algorithm for generating small-area digital elevation models (DEMs) directly from digitised aerial photographs, with no additional information required other than the flying height of the aircraft and a small number of control points measured from maps.
