Achievements
Research Interests
Affective Computing
Research is conducted to evaluate how nonverbal information such as facial expressions and gestures affects communication.
This includes emotion recognition using physiological signals (e.g., EDA and ECG) and the development of emotional expression techniques.
Persuasive Technology
This research area focuses on persuasive technologies that support users in behavior change and decision-making.
Effective persuasive methods are designed and evaluated using virtual agents and emotional elements.
Human-Agent Interaction
Studies are conducted on interactions between humans and agents, including humanoid and animal-like forms.
By combining affective computing and persuasive technology, the effects of agents’ emotional expressions and dialogue behaviors on users are evaluated, particularly in immersive environments such as VR.
Human-robot interaction is also explored using a social robot called “Furhat,” which is capable of changing facial expressions. Emotional responses are analyzed using physiological sensors.
Metaverse
Research in the metaverse focuses on communication and learning support using agents, as well as on the Proteus effect.
In addition, the mechanisms and potential applications of sensory illusions (phantom sense) in virtual and mixed reality (VR/MR) environments are being investigated.
Learning Support & Serious Games
This area explores learning through dialogue with agents, affective feedback, and serious games that promote active engagement.
Immersive learning environments using VR/MR are designed to enhance educational and training outcomes by leveraging learners’ motivation and emotional states.
Attractive Factors of the Research
Interest is particularly directed toward how non-verbal information such as emotions and virtual spaces affects humans.
This field remains full of open research questions. System development is also approached as a way to realize novel ideas for supporting human activities.
