S(C)ENTINEL: monitoring automated vehicles with olfactory reliability displays
summary
A prototype olfactory reliability display is built and attached to a simulator car and tested with N=25 in a high-fidelity driving simulator comparing three conditions: no display, visual reliability, and visual-olfactory reliability display. Two scents—lemon for low reliability and lavender for high reliability—signal system uncertainty while participants brake for slowed lead vehicles and perform a phone-based detection task. Objective driving improvements are minimal (only a tendency toward smoother braking); subjective measures show higher trust, better TAM scores and less negative affect for the olfactory condition.
