Abstract
We carried out a feeling test to make clear the dynamic characteristics of the human sense of smell. Using a first-order delay function to approximate these results, we modeled the dynamic characteristics of the sense of smell.
The simulated results from this model were used to find the optimum pattern of intermittent supply to raise arousal. The effectiveness in raising and maintaining arousal of smell supplied in this optimum pattern of intermittent release was then confirmed by experiments in a driving simulator.
