When2Talk: When Should a Proactive In-Car Agent Talk?

The study examines how proactive in‑cabin agents should communicate in fully automated vehicles, comparing an event‑triggered policy that speaks at every event with a context‑sensitive policy that chooses Immediate, Delayed, or Silent responses. In a VR simulation with 41 participants, the context‑sensitive approach improved communication appropriateness and significantly lowered perceived interruptions, while trust levels remained unchanged. The results emphasize that event consequence, passenger activity, ongoing information value, and the need for confirmation should guide selective in‑cabin communication.
