アプローチ
1.
単純な実験の実施
•
被験者は部屋でただくつろぐ
•
被験者の動作を記録
•
滞在後、感情状態の評定
2.
身体動作の定量化
感情を誘導するために
unpleasant condition (N = 10)
siren, mic feedback, scratching noise
pleasant condition (N =10)
hearing brook sounds
異なる環境音を聞く
2
条件
calm or weak emotion arousal
実験環境
感情状態を測定するために
tension
depression
anger
vigor
fatigue
confusion
LMA

への適用
estimate optical
flows for each
pixel
(using openCV)
scalar average of optical flows
variance of optical flows
the time space average of dot products between a mean vector and individual optical flows
difference of movement
strength between
continuous frames
difference of
movement direction
between continuous
frames
•||vnjk || indicates the strength
of the optical flow at pixel ij of frame n
