abstract = "The full-body control of virtual characters is a promising
technique for application fields such as Virtual Prototyping.
However it is important to assess to what extent
the user full-body behavior is modified when immersed
in a virtual environment. In the present study
we have measured reach durations for two types of
task (controlling a simple rigid shape vs. a virtual
character) and two types of viewpoint (1st person vs.
3rd person). The paper first describes the architecture
of the motion capture approach retained for the on-line
full-body reach experiment.
We then present reach measurement results performed
in a non-virtual environment. They show that the target
height parameter leads to reach duration variation
of +/-25% around the average duration for the highest
and lowest targets. This characteristic is highly
accentuated in the virtual world as analyzed in the
discussion section. In particular, the discrepancy observed
for the first person viewpoint modality suggests
to adopt a third person viewpoint when controling the
posture of a virtual character in a virtual environment."
