Design of linguistic behaviors according to driver attributes and driving situation of driving support agent based on politeness theory

Abstract

The purpose of this research is to design a driving support agent that selects utterance strategy considering driver’s attributes and driving situation based on the politeness theory. In the politeness theory, utterance strategy for constructing good relationship between people is systematized. As a concrete approach, we designed agent linguistic behaviors based on the positive politeness strategies and negative politeness strategies, which are representative utterance strategies defined in the politeness theory. In the experiment, we used two kinds of movies which reflect scenes where the driver is supported by speech synthesis utterance from agents. The utterance contents of agents were designed by us. Experiment participants watched two movies in a row and evaluated impressions for agents. Here we discuss the impression evaluation results and future development. Experiment participants are university students or graduate students with a driving experience of three years or less.
