The ToonFace coding scheme is not intended to be a competitor to FACSÑit simply provides a new way to code facial expressions that requires less detail. Control points were selected to maximize the expressivity/complexity tradeoff. Compared to prior computer systems based on FACS, ToonFace allows for animation with more of a cartoon style look. The motivation for the ToonFace control scheme has already been discussed. However, a comparison to FACS may help the interested reader get a better understanding of the limits and possibilities of this scheme. It should be noted that since the FACS coding scheme is quite complex, the FACS Manual [Ekman & Friesen 1978] is recommended for those who wish to seek a thorough understanding of the issue.
