To improve determination accuracy of determining an immersion degree of a subject on the basis of a brain activity signal from the subject.SOLUTION: An immersion degree determination method detects brain activity signals in a central region and a rear region of the brain of a subject (S1), detects the nictitation of the subject (S2), measures the functional connectivity between the central region and the rear region on the basis of the detected brain activity signals (S3), and determines an immersion degree of the subject on the basis of the presence or absence of the functional connectivity in the first period from the detection of the nictitation to the elapse of the first prescribed time, and the presence or absence of the functional connectivity in the second period from the point after the first period to the elapse of the second period (S4-S10).SELECTED DRAWING: Figure 5

    【課題】被験者からの脳活動信号に基づいて被験者の没入度合いを判定する判定精度を向上する。【解決手段】没入度合い判定方法では、被験者の脳の中央領域及び後方領域の脳活動信号を検出し(S1)、被験者の瞬目を検出し(S2)、検出された脳活動信号に基づいて中央領域と後方領域との間の機能的連結性を測定し(S3)、瞬目を検出した時点から第1所定時間が経過するまでの第1期間における機能的連結性の有無と、第1期間以降の時点から第2所定時間が経過するまでの第2期間における機能的連結性の有無に基づいて、被験者の没入度合いを判定する(S4~S10)。【選択図】図5
