Abstract

Latency in a communication system can result in
confusing a conversation through loss of causality as people
exchange verbal and non-verbal nuances. This paper compares
true end-to-end latencies across an immersive virtual
environment and a video conference link using the same
approach to measure both. Our approach is to measure end-to-end
latency through filming the movements of a participant
and their remote representation through synchronised
cameras. We also compare contemporary and traditional
immersive display and capture devices, whilst also measuring
event latency taken from log files. We compare an immersive
collaborative virtual environment to a video conference as both
attempt to reproduce different aspects of the face-to- face
meeting, the former favouring appearance and the latter
attention. Results inform not only the designers of both
approaches but also set the requirements for future
developments for 3D video which has the potential to faithfully
reproduce both appearance and attention.
