摘要:We present redirection techniques that support exploration
of large-scale virtual environments (VEs) by
means of real walking. We quantify to what degree
users can unknowingly be redirected in order to guide
them through VEs in which virtual paths differ from
the physical paths. We further introduce the concept of
dynamic passive haptics by which any number of virtual
objects can be mapped to real physical proxy props
having similar haptic properties (i. e., size, shape, and
surface structure), such that the user can sense these
virtual objects by touching their real world counterparts.
Dynamic passive haptics provides the user with
the illusion of interacting with a desired virtual object
by redirecting her to the corresponding proxy prop.
We describe the concepts of generic redirected walking
and dynamic passive haptics and present experiments
in which we have evaluated these concepts. Furthermore,
we discuss implications that have been derived
from a user study, and we present approaches
that derive physical paths which may vary from the
virtual counterparts.
