Abstract
Reorientation techniques address the challenge of overcoming the limited interaction
space when using real walking for locomotion in immersive virtual environments by
introducing discrepancies between a user's physical and virtual rotation. To avoid breaks in
presence, manipulations during reorientation should be applied with intensities that are unnoticeable
to the user. Therefore, in psychophysical experiments detection thresholds have
been determined up to which users can be unknowingly manipulated. However, until now,
the in
uence of di erent virtual scene layouts on the detectability of manipulations has not
been analyzed.
In this paper we have examined the in
uence of visual orientation cues on the ability of users
to detect discrepancies between real and virtual head rotations. Therefore, we conducted a
psychophysical experiment in which we compared two scene layouts providing di erent visual
orientation cues. Our results show that the strong visual orientation cue condition leads to
a 25% decrease of the interval in which subjects are not able to detect manipulations, i. e.,
subjects are more sensitive to manipulations, compared to the weak visual orientation cue
condition, which motivates the importance of scene layout on reorientation techniques.
