When expressing information about spatial domains, humans frequently accompany their speech with iconic gestures that depict spatial, imagistic features. For example, when giving directions, it is common to see people indicating the shape of buildings, and their spatial relationship to one another, as well as the outline of the route to be taken by the listener, and these gestures can be essential to understanding the directions. Based on results from an ongoing study on gesture and language during direction-giving, we propose a method for the generation of coordinated language and novel iconic gestures based on a common representation of context and domain knowledge. This method exploits a framework for linking imagistic semantic features to discrete morphological features (handshapes, trajectories, etc.) in gesture. The model we present is preliminary and currently under development. This paper summarizes our approach and poses new questions in light of this work.
