Plane Sweeping in Eye-Gaze Corrected,
Teleimmersive 3D Videoconferencing
Maarten Dumont, Patrik Goorts and Gauthier Lafruit
Abstract
A teleimmersive videoconferencing system for autostereoscopic 3D
displays is presented. Eye contact between participants is restored by synthesizing
novel, interpolated views frommultiple surrounding cameras, effectively emulating a
capturing camera position behind a virtually transparent display. Nonuniform, adap-
tive plane sweeping with dynamic workload balancing yields real-time performances
on low-cost embedded GPU platforms.
6.1 Introduction
Imagine a world with perfect immersive teleconferencing, where people are able to
communicate remotely with an intense sense of human awareness that would be vir-
tually indistinguishable from real-life social communication. People would be able
to communicate seamlessly with their friends and family thousands of miles away.
Face-to-face meetings would be enabled without the need to travel, and telecollabo-
ration would reach the holy grail of

of immersion.
And yet, in spite of all the work already done in immersive teleconferencing and
the high level of quality reached in today's video capturing and rendering technology,
this ultimate dream remains unrealized. What are the potential causes and how can
technology provide a solution to this problem?
