The Expressive Gaze Model: Using Gaze to Express Emotion

摘要

Gaze is an important but understudied signal for displaying emotion. The Expressive Gaze Model (EGM) is a hierarchical framework for composing simple behaviors into emotionally expressive gaze in virtual characters that encompasses eye, torso, and head movement. The EGM's primary components are the Gaze Warping Transformation (GWT), which generates emotionally expressive head and torso movement in a gaze shift, and an eye movement model. Researchers have used the EGM to produce several types of gaze shift, both with and without explicit emotional behavior.
