Development of a Speech-Driven Embodied Color-Changed Entrainment System

Abstract

InterActor is the speech-driven embodied entrainment character for activating human interaction and communication by embodied rhythms between speech and body motions such as nodding in human face-to-face conversation. In this paper, to clarify the visual effect of color change of entrainment on interaction support, a speech-driven entrainment color-changed entrainment system is developed. The system changes color on an object with a visualized response equivalent to nodding in the same timing as InterActor to speech input. By using the system, sensory evaluation by paired comparison demonstrates the effect of color change from the result that the pattern that the color changes from the top of the object is more desirable than the pattern that the whole color changes at a moment.
