　View Summary

This study investigated the effects of a method of anthropomorphizing a target space using attachable robotic human parts. As a result of this method, users may perceive a space as having lifelike characteristics and may accept a virtual body image for various objects. We developed robotic human parts to evaluate our method and conducted an experiment in which subjects positioned objects according to instructions given within an anthropomorphic space to determine their acceptance of the virtual body images presented and the anthropomorphic representation of the space. The results showed that subjects' positioning of objects changed according to the position of the human parts. We found that our method successfully generated a virtual body image for a particular region that would not normally be recognized in this way by users.

"Display Robot" - Interaction between Humans and Anthropomorphized Objects.

　View Summary

We propose a '' display robot '' that directly anthropomorphizes objects using body parts that are like those of humans. It is constructed of devices that look like eyes and arms. It anthropomorphizes objects according to the places they are located at or the situations they are in, and this increases their subjectivity and their virtual body image. The display robot enables users to accept the body images of objects and communicate smoothly with them. We assessed user evaluations of the display robot in an exhibition space and in this paper we discuss the effect of anthropomorphization achieved by these devices.

Acquisition of Body Image by Anthropomorphization Framework

　View Summary

In this study, we propose anthropomorphization framework that determines object's body image by attaching it to human-like body parts. Our purpose is that an object acquires subjective representation by anthropomorphization and it communicates with humans. Although, there are many studies on anthropomorphic agents to communicate with humans via an object, it's unnatural because these agents are unrelated to the object directly. In our method, the object is directly anthropomorphized so it can conduct task-related communication using its intrinsic body image. We designed anthropomorphization framework that changes body image by attaching places of body parts. We also conducted an experiment to evaluate this framework. The result indicates that an attached place of anthropomorphize device influences human's perception for body image.

Designing human-robot interaction via physical world objects

　View Summary

This paper proposes a new communication model based on physical world objects. In usual human-robot interaction, a human looks on the robot's behaviors without responding to them and seldom immerses him/herself in the interaction. The communication model achieves human's immersion in interaction with two types of behaviors. The first draw's human's attention to a physical world object or a physical world state. The second stimulates a human's feeling under the attention. The novel idea of the model is to employ the actual physical objects to mediate the human-robot interaction. In particular, since the second behavior relates directly to a sort of human's sensory perception, it is easy for a human to become aware of the referent of the robot's behavior. As a result of the two behaviors, he/she begins to infer robot's intentions and immerses him/herself in the interaction.
