Scott is correct in saying "the physical body (and moving) seems to be at
the center of these discussions". I think this is because several of us are
attempting to sense the language of movement and to use that information as
a source of control over media. This can be seen as our attempt to add yet
another layer of language to the language of movement.
Still, there is no reason that this same technology could not be used
effectively in theater. In theater the actors movement is not intended to
be the primary means of communication, but that same movement could be used
to control elements of the overall presentation, including modulation of
the actor's voice.
