Expression training for complex emotions using facial expressions and head movements

Imitation is an important aspect of emotion recognition. We present an expression training interface which evaluates the imitation of facial expressions and head movements. The system provides feedback on complex emotion expression, via an integrated emotion classifier which can recognize 18 complex emotions. Feedback is also provided for exact-expression imitation via dynamic time warping. Discrepancies in intensity and frequency of action units are communicated via simple graphs. This work has applications as a training tool for customer-facing professionals and people with Autism Spectrum Conditions.
