This paper describes an Augmented Reality (AR)
Videoconferencing System, which is a novel remote
collaboration tool combining a desktop-based AR
system and a videoconference module. The novelty of
our system is the combination of these tools with AR
applications superimposed on live video background
displaying the conference parties’ real environment,
merging the advantages of the natural face-to-face
communication of videoconferencing and AR’s
interaction capabilities with distributed virtual objects
using tangible physical artifacts. The simplicity of the
system makes it affordable for everyday use. We
explain our system design based on concurrent video
streaming, optical tracking and 3D application sharing,
and provide experimental proof that it yields superior
quality compared to pure video streaming with
successive optical tracking from the compressed
streams. We demonstrate the system's collaborative
features with a volume rendering application that
allows users to display and examine volumetric data
simultaneously and to highlight or explore slices of the
volume by manipulating an optical marker as a cutting
plane interaction device.
