The process for navigation tasks under shared situation

Abstract

We analyzed the processes by which people achieve speech-based navigation tasks under the shared situation using the Konbini Corpus [Raux 10]. We observed that there were several behaviors, interactions and communications that could not be explained by existing theories. Existing theories assume that people need to share their plans in order to achieve their common goal. (e.g. Shared Plan model: [Cohen 91, Grosz 90, Traum 94]). On the contrary to those theories, the participants in the Konbini Corpus successfully achieved their common goal without developing clear mutual beliefs about their goals nor plans. The results showed that participants usually started their actions without developing concrete mutual beliefs, and their actions were either self-corrected or interposed by other members in the middle of the actions. In order to explain these results, we proposed necessary requirements for a new model.
