Human-robot interaction is a research field to study how to interact with human and robot.

In this field, we study how we can achieve safe interaction can be achieved when we interact with robots in our daily life. We also study how we can achieve long-term interaction in our daily life.

When we consider human-robot interaction, we need not only engineering approach to achieve safely or reliability but also psychological approach.

In our laboratory, we consider human-robot interaction from both aspects such as:

- Imcomplete robots design and its positive effect in human-robot interaction.

- Previous notice using breathing system

- Human-robot interaction throughout the object

Imcomplete robots design and its positive effect in human-robot interaction

In recent years, many robots for interacting humans have actively been studied. How to attract users is a key topic in human-robot interaction and entertainment field. Although robot designers often aim to design the robot to be free of imperfections, we also know an old proverb; The sillier the child is, the cuter he or she is. The aim of this study is to investigate the positive effect of sillier robots in human-robot interaction.

Previous notice of robotic motion using breathing system

In this research, we aim to study the previous notice of robotic motion using breathing system. It is expected that users can perceive the danger from the system. The purpose of this study is to investigate change of examinee’s fear when a breathing system is used.

A study on robot behavior model to build causality after events

In this study, we pay attention to causality illusion, and aim to analyze it and to apply it to engineering fields. We are currently investigating causality illusion by using some mobile robots in the smart environment.

Human-robot interaction throughout the object

We are developing a simple tactile sensor with three pressure sensors, and apply it to an industrial robot. We progress the research on surface normal sensing, shape measurement and object edge detection by using our tactile sensor system.

Nonverbal interaction based on virtual field model

We are studying a unified interaction model to handle contact interaction and non-contact interaction. In our approach, we set a virtual field like gravity field around the robot, and aim to control the robot throughout the virtual field.
