We present a new algorithm for the generation
of multimodal referring expressions
(combining language and deictic
gestures).1 The approach differs from
earlier work in that we allow for various
gradations of preciseness in pointing,
ranging from unambiguous to vague
pointing gestures. The model predicts
that linguistic properties realized in the
generated expression are co-dependent
on the kind of pointing gesture included.
The decision to point is based on a tradeoff
between the costs of pointing and the
costs of linguistic properties, where both
kinds of costs are computed in empirically
motivated ways. The model has
been implemented using a graph-based
generation algorithm.
