Evaluation of a dialogue manager for a mobile robot

This paper presents an evaluation of the dialogue manager (DM) used on Carl, a prototype of an intelligent service robot, designed and developed having in mind hosting tasks in a building or event. The developed DM, based on the “Information State” approach, is described. In an experimental evaluation, in which 10 participants attempted to complete several interaction tasks with the robot, 81% of tasks were performed successfully. The results of an usability evaluation are also presented and discussed.
