An integrated design and evaluation tool for dialogue systems in vehicles

A program tool is presented that integrates design and evaluation of dialogue systems in motor-cars. The design component is realized with a prototyping tool for user interfaces. The evaluation component is based on an approach modelling the driver's task-related knowledge by means of production systems. Cognitive complexity measures of driver-vehicle interactions, such as visual distraction, learning and execution time are derived. The integration of design and evaluation is achieved by generating the production system models of the driver's tasks automatically when the tasks are executed with the prototyped dialogue system.
