An Expressive Eye Model: Using Eye Movement to Show Ocular Emotional Expression

Abstract

Emotionally expressive eye movement is important for facial animation. However, relation between eye movement and emotions has not been well studied. This paper integrates various sources of information to create an expressive eye model capable of expressing different emotions through vivid eye movements. First, based on statistical data and experimental studies, we endow eye model with detailed motion parameters and functions, with which detailed eye movement under neutral emotion state can be displayed. Second, an eye tracking experiment is performed to find the impact of emotional change on eye movements, and then the analysis result of tracking data are used to model eye movements under different emotion conditions. Experiment demonstrates that our eye model can reflect emotional changes of virtual character through different eye movement patterns.
