Abstract
In order to enhance the quality of facial expressions used in interactive media, typically video games, a system for generating facial animation and influencing their characteristics and temporal change in real-time is proposed, implemented and evaluated. The proposed system takes into account the underlying muscles of the human face and how they interact in order to approximate a simulation-like quality, though appropriated for real-time rendered animations. All this is done using the Facial Action Coding System (FACS) developed by Paul Ekman [1][2] as well as studies related to gaze and head movement by Argyle & Cook [3] as well as Hader et. al. [4] The system is partially controlled by the developer, but adds layers of detail in order to make the face feel less artificial. These extra details are added by the system. Further development would focus on developing an Acting Emulator capable of handling different emotions and perhaps eventually extract cues from speech audio files used as markers for conversational actions.
