GibbonFACS is a modification of the original human FACS (Ekman  & Friesen 1978), for use with hylobatid species (gibbons and siamangs) and was established following the same methods used in the development of ChimpFACS, MaqFACS and OrangFACS.

 

The resulting GibbonFACS Manual is an additional, freely available tool for scientists interested in comparative communication research, supporting already existing facial action coding systems to studying facial expressions.
