摘要

脑电图包含了丰富的脑电活动信息，但我们只了解了其中的一小部分。心理状态表现为脑电图的时空行为。头皮电极采集的脑电信号相互关系数集合形成一个状态向量。感兴趣的情绪状态占据了一个小的子空间，这个子空间是由四个正交的基本状态所跨越的，即愤怒、悲伤、快乐和放松。这种方法被称为ESAM。该系统目前被用于分析对电视广告的情绪反应、汽车的噪音、家具的舒适度等。

Numerical estimation of the state of mind

The EEG is rich with information on electric brain activity but only a small part of it has been understood. The state of mind is manifested in spatial-temporal behavior of EEGs. The set of cross-correlation coefficients of EEGs collected with scalp electrodes forms a state vector. The emotional state under interest occupies its small subspace which is spanned by the four orthogonal elementary states referring to anger, sadness, joy, and relaxation. This method is called ESAM. This system is currently used for analyzing emotional responses to TV commercials, acoustic noise of automobiles, comfortableness of furniture, etc.
