眼球运动与嘴唇同步、眼球运动和情绪面部表情相结合，揭示了一个有趣的研究领域，它提供了关于人体内发生的语言和非语言行为的信息。以往的研究大多集中在眼睛凝视、嘴唇同步和情绪表达上，这些都是传递非语言信息以增强、理解或表达情绪的最重要的特征。本文介绍了3D面部表情的最新进展，重点介绍了XFace平台工具包，该工具包通过实现文本到语音引擎(TTS)来描述每个音素传达对话所需的基本嘴唇形状，从而开发了3D语音化身合成。这项工作被认为是未来的方向，可以导致新的面部动画研究问题。
Eye movement combined with lip synchronization, eye movements, and emotional facial expression revealed an interesting research field that gives information about verbal and nonverbal behaviors occurring in the human body. Most of the previous researchers focused on eyes gazes, lip synching and emotion expression which are the most important features that can transfer nonverbal information to enhance, understand or express emotion. In this paper, the recent advances in 3D facial expression are introduced focusing on the presentation of Xface platform toolkit that developed a 3D talking avatars synthesis by implementing text-to-speech engine (TTS) to depict the basic lip shapes necessary for each phonemes to convey the dialogue. This work is believed to give the future direction that can lead into new research issue in facial animation.
