Abstract

<p>仮想現実を用いれば,現実では実施することが難しい特殊な環境・状況で,脳がどのように情報処理を行うのかを検討することが可能となる.認知神経科学ではEEGやfNIRSなどの計測技術を用いて基礎から臨床に渡り,多様な研究が行われてきた.本稿では,最初にfNIRSを含む脳活動計測技術の概説と,これら計測技術を用いたVR体験時の脳機能を検討した先行知見を説明する.次に,VRという新しい産業分野における著者らの事例:1) 2D動画と3DCG動画との視聴中脳活動の比較,2) VRを用いた技能実習中の脳活動の観察について紹介し,最後にVR技術とfNIRS計測技術とを組み合わせた産業応用の可能性について述べたい.</p>

<p>Virtual reality (VR) has been applied in cognitive neuroscience research in the last few decades. Researchers have been interested in neural responses to unique experiences that are difficult to realize in real experimental situations, but possible in VR, including operating airplanes and addressing phobic objects. Furthermore, using VR for clinical purposes such as rehabilitation has also been steadily growing. In this section, we first introduce to common neuroimaging techniques (EEG, fMRI, fNIRS) and summarize some of the recent works, in which the brain activities were monitored in VR. We then report preliminary results from two experiments which we carried out with using VR-fNIRS. In the first study, we compared prefrontal activities during watching a short film in VR with watching the same movie in PC monitor. In the second study, we monitored prefrontal activity during VR-technical training. Last, future perspectives of VR-fNIRS for industrial application will be discussed.</p>
