Empirical Design of Interaction with Vague Embodied Robot

Abstract

In this paper we investigate whether interactive attention should be achieved jointly between a human and a vague embodied robot. It is known that joint attention by means of eye-gazing, finger-pointing or other verbal or non-verbal indication between humans plays an important role in making conversation smoothly and fulfilling sympathy for each other.While the effect of joint attention has been proved between humans and robots, the purpose of our paper is to realize interactional alert between a human and an vague embodied robot by using demonstrative pronunciations such as "this" and "that" referred by the robot as well as its physical distance and position from the human participant.
