面部表情在日常互动中起着重要作用。大多数关于面部表情的研究都集中在一小部分“基本”状态上。然而，在现实生活中，情绪的表达是高度依赖于上下文的，并且“基本”情绪的原型表达可能并不总是存在的。在本文中，我们试图根据观察到的面部反应的非常大的数据集来发现与知情、受启发、被说服、感伤和有趣的交替状态相关的表情。我们使用了一组精心策划的395个日常视频，这些视频被发现可以可靠地引出状态，并记录了49，869个面部反应，因为观众在家中观看视频。使用自动面部编码，我们量化了2340万帧中每帧中18个面部动作的存在。在情感反应中，嘴角拉、嘴唇吮吸和内眉提升是突出的。外眉扬起和眼睛睁大是明显的说服和知情的反应。更多的皱眉将知情与说服的反应区分开来，可能表明更高的认知能力。
Facial expressions play a significant role in everyday interactions. A majority of the research on facial expressions of emotion has focused on a small set of "basic" states. However, in real-life the expression of emotions is highly context dependent and prototypic expressions of "basic" emotions may not always be present. In this paper we attempt to discover expressions associated with alternate states of informed, inspired, persuaded, sentimental and amused based on a very large dataset of observed facial responses. We used a curated set of 395 everyday videos that were found to reliably elicit the states and recorded 49,869 facial responses as viewers watched the videos in their homes. Using automated facial coding we quantified the presence of 18 facial actions in each of the 23.4 million frames. Lip corner pulls, lip sucks and inner brow raises were prominent in sentimental responses. Outer brow raises and eye widening were prominent in persuaded and informed responses. More brow furrowing distinguished informed from persuaded responses potentially indicating higher cognition.
