In facial animation, the research trend is an eye gaze and voice modeling. However, the incorporation of eye movement, lip synchronization, and facial expression are necessary for a more realistic face model. This paper provides a thorough survey of facial animation with respect to eye movement, lip synchronization, and facial expression research. The significance of this survey paper is to provide a review of existing literature, giving insight to various approaches that have been proposed for problems in facial realistic modeling. More also, this survey is to open-up a new research direction in facial animation.
