Abstract / Description:Even in state-of-the-art virtual reality (VR) setups, participants often
feel lost when navigating through virtual environments. In psychological
experiments, such disorientation is often compensated
for by extensive training. The current study investigated participants’
sense of direction by means of a rapid point-to-origin task
without any training or performance feedback. This allowed us to
study participants’ intuitive spatial orientation in VR while minimizing
the influence of higher cognitive abilities and compensatory
strategies. After visually displayed passive excursions along oneor
two-segment trajectories, participants were asked to point back
to the origin of locomotion "as accurately and quickly as possible".
Despite using a high-quality video projection with a 84deg×63deg field
of view, participants’ overall performance was rather poor. Moreover,
six of the 16 participants exhibited striking qualitative errors,
i.e., consistent left-right confusions that have not been observed in
comparable real world experiments. Taken together, this study suggests
that even an immersive high-quality video projection system
is not necessarily sufficient for enabling natural spatial orientation
in VR. We propose that a rapid point-to-origin paradigm can be a
useful tool for evaluating and improving the effectiveness of VR
setups in terms of enabling natural and unencumbered spatial orientation
and performance.
