We present a collaborative approach towards a detailed understanding of
the usage of pointing gestures accompanying referring expressions. This
effort is undertaken in the context of human-machine interaction
integrating empirical studies, theory of grammar and logics, and
simulation techniques. In particular, we attempt to measure the
precision of the focussed area of a pointing gesture, the so-called
pointing cone. The pointing cone serves as a central concept in a
formal account of multi-modal integration at the linguistic
speech-gesture interface as well as in a computational model of
processing multi-modal deictic expressions.
