In this paper, we examine the acceptability of a driving situation announce agent for fully automated driving. A driving situation announce agent is a method of notifying a user of a fully automated vehicle of the presence or absence of surrounding vehicles and the driving operations to be performed by the automated driving system through spoken utterances and gestures. We designed agent speech and gestures for driving situations such as merging with other vehicles and intersections, and evaluated the acceptability of the agent to a fixed number of experimental participants (n = 600) through a video-based impression evaluation experiment. The experimental results show that the agent’s acceptability may not change drastically depending on the size or presence of gestures, while the user’s confidence in driving and anxiety about automated driving are significantly related to acceptability, and the tendency of the relationship varies depending on the size or presence of gestures. These findings are useful for the design of in-vehicle agents for fully automated vehicles.
