Increasing the User Experience in Autonomous Driving through different Feedback Modalities
summary
Built a Unity VR prototype and runs a within‑subject study with 22 participants who experience four driving scenarios and five unimodal cues plus a no‑feedback baseline. Finds light and visualisation improve user experience significantly versus baseline; 18 participants call light useful though 12 say its gradients are too complex, 7 find visualisation helpful and 8 feel reassured. Sound is pragmatic but not significant. Prefers softer cues for proactive and stronger cues for reactive situations.
