Development of a Pupil Response Model Synchronized with Burst-Pause of Utterance Based on the Heat Conduction Equation

Abstract

In our previous study, we performed the analysis of pupil response during his / her utterance by using a pupil measurement device and demonstrated that speaker's pupil response dilates with synchronization to the burst-pause of utterance. In addition, we developed a pupil response robot called “Pupiloid” that generates the pupil response with mechanical structure, and demonstrated that the pupil response is effective to express own affect. In this paper, in order to realize a smooth communication during human and robot interaction, we propose a pupil response model synchronized with burst-pause of utterance based on the heat conduction equation. This model estimates the degree of affective conveyance and generates the pupil response based on the estimated value.
