Computational Analysis of Emotion Dynamics

Abstract

Emotions are dynamic. They vary continuously with regard to intensity, duration, persistence with time, and other attributes. In addition, their appearance on the face of subjects varies, and the transition in facial expressions is based on both the change in emotion and physiological constraints. In this paper, we examine the trajectories between emotions in activation-evaluation space and show that emotion trajectories are smooth and follow `common' paths between different emotions.
