Research Contents

1. In the human interface group,
we are researching ways to assist the engagement of people with people, and people with systems. For example, research and development of systems to support communication between people, and research and development of systems that interactively present a person’s movements, exercise, and those results to themselves to encourage self-development based on internal motivation. In addition, in the emotional stress measurement field, which has used contact sensors, we are conducting research on estimating emotional stress using non-contact sensors. We are also researching shape evaluation based on Kansei such as the beauty and complexity of objects in real and virtual spaces.
2. In the acoustic group,
we are researching numerical simulation technologies for problems related to general wave phenomena, from sound waves to electromagnetic waves. In particular, by the development of specialized sound field rendering hardware, we are aiming to achieve a “silicon concert hall” to reproduce concert hall sound in real-time.
