Gaze Conformation for L2 Automated Maneuvers
Johannes Illgner, Nataša Miličić, Martin Baumann · 2025
With the rapidly advancing capabilities of Level 2 (L2) automated systems the need for driver confirmation of complex maneuvers, such as entering roundabouts, has been increasingly emphasized to ensure active engagement and safety. This study contrasts confirming maneuvers through control gazes with traditional explicit methods like accelerator use to facilitate seamless interaction and promote the adoption of L2 systems. A simulator study involving 64 participants demonstrated a clear preference for the gaze confirmation system, with significantly higher ratings for user experience, acceptance, and intention to use, without compromising trust compared to explicit confirmation. Participants intervened in case of system failures with either system. The results are building a strong case for daring advanced automation via gaze confirmation to harness progress of L2 systems while preserving safety.
