| Outline of Final Research Achievements |
The objective of this project is to synthesize a three-dimensional environment to support human intellectual and affective activities. In this project, we focused on the effectiveness of auditory information because humans perceive the impressions and atmospheres of various environments through auditory cues. Additionally, it is important to consider the humans themselves who share the environment. Therefore, we aimed to reproduce an appropriate auditory space for these activities, taking into account the interaction between humans and the environments.
Throughout the research period, we successfully developed several fundamental technologies for auditory space synthesis, including high-precision auditory space recording and reproduction techniques using distributed spherical microphone arrays, near-field head-related transfer function synthesis methods, and the perceptual mechanisms of affective multi-modal environments that incorporate audio-visual and vibration information.

| Academic Significance and Societal Importance of the Research Achievements |
人間がバーチャル環境で協働，協奏して知的感性活動を行うような機会は増えており，本研究の成果は，そのような環境をより人間に適した形で構築するための基盤となるものである。したがって，単にアミューズメントなどのエンターテインメントの分野だけでなく，遠隔教育などの分野にも波及が期待される。また，研究を通して明らかとなった人間の知覚感性メカニズムは，工学のほか，心理学，情報学などに対しても寄与が見込める学際的な成果と考えている。
