A cognitive model for the process of multimodal, incremental route descriptions

Abstract

In normal life we often give route descriptions to inform someone about a specific route. They can be divided into the classes of complete and incremental route descriptions. We propose that the multimodal, incremental route description process consists of a wayfinding, a waypresentation and a control process and is based on a segmentation hierarchy. The presentation of a route description is characterized by the use of different presentation modi like speech, gesture and graphics. We propose a computational model for the multimodal, incremental route description process.
