When drowsiness detection is unreliable or absent, conventional on-demand driver vigilance enhancement approaches become ineffective. We propose a new, detector-free method to provide an alert signal to a driver in this case. Its unique triggering mechanism is based upon our hypothesis that as one becomes sleepy, his pain threshold lowers and an otherwise below-threshold stimulation becomes painful. We use the pain illusion phenomenon to construct a user-tailored innocuous thermal alert signal, to be triggered only by a host’s own declining vigilance state, to produce a noxious response. This response will serve to arrest and eventually raise the host’s arousal, when noxious sensation would disappear completely, automatically. In this paper, we present the design rationale, prototype instrumentation and preliminary findings from testing this hypothesis.
