Abstract:

Humans tend to interact with machines in the same way they do with other
human beings.  During face to face communication, people are able to
easily recognize the subtleties of different facial expressions with no
effort. For that reason, animated faces may be used as a transparent
human-robot interface that people can interpret.  On the other hand,
humans transmit great part of the information via nonverbal channels,
mainly facial expressions. Building  an interface with the capability
of recognizing those signals helps in the use and acceptance of social
robots, as users can interact with them in a more natural way.
The lecture will describe the development of a multimodal 3D animated
head, taking robotic characteristics into account and searching for
a convergence between these characteristics, real facial actions and
animation techniques. The multimodal system is able to display simple
and complex facial expressions and also to recognize them.  Both facial
animation and expression recognition systems are based on Facial Action
Coding System's (FACS) Action Units (AUs).
