Pointing in Visual Contexts
In D. Schlangen & R. Fernandez (Eds.), Proceedings of

We describe an experiment to gather original data on geometrical
aspects of pointing. In particular, we are focusing upon the concept of
the pointing cone, a geometrical model of a pointing's extension. In
our setting we employed methodological and technical procedures of a
new type to integrate data from annotations as well as from tracker
recordings. We combined exact information on position and orientation
with rater's classifications. Our first results seem to challenge
classical linguistic and philosophical theories of demonstration in
that they advise to separate pointings from reference.
