I Can See on my Feet While Walking: Sensitivity to Translation Gains with Visible Feet
Redirected walking allows users to explore immersive virtual envi-
ronments by real walking even when the physical tracking space is
limited. Redirected walking is usually implemented via translation
gains, rotation gains, and curvature gains, while previous research
was focused on identifying detection thresholds for such manipula-
tions. To our knowledge, all previous experiments were conducted
without a visual self-representation of the user in the virtual en-
vironment, in particular, without showing the user’s feet. In this
paper, we address the question if the virtual self-representation of
the user’s feet changes the detection thresholds for translation gains.
Furthermore, we consider the influence of the holisticness of the
visual stimulus, i. e., the type of virtual environment. Therefore,
we conducted an experiment to identify detection thresholds for
translation gains under three different conditions: (i) without visible
virtual feet and (ii) with visible virtual feet both in a high fidelity
visually rich virtual environment, and (iii) with visible virtual feet
in a low cue virtual environment. The results revealed the range of
detection thresholds for translations gains, which cannot be detected
by the user when the feet are visible. Furthermore, the results show
a significant difference between the two types of environment. Our
findings suggest that the virtual environment is more important for
manipulation detection than the visual self-representation of the
user’s feet.
