Actors in virtual studio productions are faced with the challenge
that they have to interact with invisible virtual objects
because these elements are rendered separately and combined
with the real image later in the production process. Virtual
sets typically use static virtual elements or animated objects
with predefined behavior so that actors can practice their performance
and errors can be corrected in the post production.
With the demand for inexpensive live recording and interactive
TV productions, virtual objects will be dynamically rendered
at arbitrary positions that cannot be predicted by the
actor. Perceptive aids have to be employed to support a natural
interaction with these objects.
In our work we study the effect of haptic feedback for a simple
form of interaction. Actors are equipped with a custom
built haptic belt and get vibro-tactile feedback during a small
navigational task (path following). We present a prototype of
a wireless vibro-tactile feedback device and a small framework
for evaluating haptic feedback in a virtual set environment.
Results from an initial pilot study indicate that vibrotactile
feedback is a suitable non-visual aid for interaction that
is at least comparable to audio-visual alternatives used in virtual
tactile feedback, interaction in virtual sets, navigation aids
