    • Project

  • ■ Group Dynamics in VR Group Discussions (2022-):
  • In recent years, social VR has become increasingly important, and VR group discussions have attracted a lot of attention. Indeed, VR group discussion is used in business, education, etc. This project is to understand the mechanisms of group dynamics that occur in VR group discussion. For the survey, both objective evaluation (e.g., avatar's behavior in VR space, user's behavior in real space) and subjective evaluation (e.g., questionnaire) are used.
  • Keywords: Virtual Reality, Metaverse, Group Dynamics, Remote Collaboration, Decision-making
  • ■ AI-based Decision-making, Human-AI Collaboration (2023-):
  • AI-based decision-making is expected to lead to better decision-making, and human-AI collaboration(such as Chat-gpt) has become widespread in society. On the other hand, users' overreliance in AI can lead to lower quality of decision-making. This project is to investigate and develop an AI-human interface to guide better AI-based decision-making.
  • Keywords: Human-AI Collaboration, AI-Based decision-making
  • ■ VR system for psychiatric disorders (2023-):
  • We are developing a VR system for mental disorders. For example, we are aiming to measure social cognitive functions, which are strongly related to schizophrenia, in a way that is more realistic by using VR.
  • Keywords: VR, Social Cognitive function, psychiatric disorder
