MULTIMODAL FACIAL RIGGING: TOWARDS A USER-ADAPTED ANIMATION INTERFACE.

Animating a character's face is a strenuous task due to a lack of a consensus among 3D artists on how to build and provide the controls in an animation-ready facial rig. To help provide a uniform integrative of control interaction to facial animation, a multimodal rig interface system approach was developed and tested in an initial user experiment with 15 digital artists. The users requested improvements and the system was upgraded into a user-adapted multimodal approach that supports a synchronized input of its different interaction modes and a scalable control of the facial deformation. This paper describes the algorithms behind the user-adapted system and a follow-up user experiment with 20 professional expert character animators. The results and user scores help clarify the relevance of the user-adapted multimodal rig interface system approach as an interaction model that decreases the effort required to animate a character's face.
