EMFACS — Emotional FACS
A subset of FACS that scores only the Action Units that have been empirically linked to emotional meaning, allowing faster coding when the research question is affective.
EMFACS (Emotional FACS) was developed by Ekman and Friesen as an efficient subset of full FACS for research on expression patterns associated with affective categories.
Some facial analytics systems map detected AUs to category probabilities or dimensional scores. These are model estimates and do not verify a person's emotion or mental state.
