A Study of the Relation Between Linguistic Considerations and Reliability/Annoyance of Driver Assistance Robots in Automatic Destaging Notifications

Abstract

In this paper, we examine the effects of the linguistic consideration strategy used by a driver assistance robot to notify the cancellation of the automatic driving phase on reliability and annoyance. The research method was based on the linguistic consideration strategy in the politeness theory, which was designed as a reference for the phase cancellation notification utterance. A video-based experiment was conducted by crowdsourcing 240 experiment participants to subjectively evaluate the driver assistance robot’s utterances in terms of reliability and annoyance. The results showed that the “include both speaker and listener in the action,” “give reasons,” and “show respect” strategies and direct speech without linguistic consideration tended to be more reliable and less bothersome in all six stages of the automatic deactivation phase.
