HapFACS
Open source software/API for generating FACS-based facial expressions on 3D conversational agents 

Picture
Our HapFACS open source software for facial expression generation based on Ekman's (1992) Facial Action Coding Systems (FACS) - the current standard on facial coding of the human face - enables: 

  1. researchers on 3-dimensional animated characters - without expertise in computer graphics nor in FACS - to design a set of FACS-based facial expressions on the Haptek virtual character platform and to integrate their expressive avatars in their applications; and 
  2. researchers on facial expression recognition to experiment with realistically generated expressions at the level of 49 individual Action Units (AUs), including bilateral (49 AUs) and unilateral (14 AUs).

Our work is further described in the following article:

Lisetti (2013) HapFACS: an Open Source API/Software to Generate FACS-Based Expressions for Embodied Conversational Agents Animation and for Corpus Generation.  In Proceedings of the Affective Computing and Intelligent Interaction Internal Conference (ACII) , (Geneva, SWITZTERLAND, September, 2013) [PDF].
