Facial expression tools for video have revealed new findings in how humans
respond to each other facially and offer incidentally, opportunities for
hidden manipulation of political presentation. The following is from ACM

Weta Finds Way to Manipulate Real Facial Expressions New Zealand Press
Association (06/01/09)
Researchers from Weta Digital and universities in the United Kingdom and the
United States have developed software for "cloning" facial expressions. The
researchers examined established assumptions about human behavior and
influences on behavior when communicating by tracking the expressions of
individuals during live conversations through videoconferencing and mapping
the facial movements to model faces. The researchers found that facial
expressions and head movements can be manipulated in real time to alter the
apparent expressiveness, identity, race, and even gender of someone
communicating through videoconferencing. "These visual cues can be
manipulated such that neither participant in the conversation is aware of
the manipulation," the researchers say. The software is now being tested by
psychologists interested in challenging preconceived assumptions about how
humans behave while communicating. Previous research found that speakers
move their head differently when speaking to a women than when speaking to a
man, and the new software has helped show that this difference is not
because of the woman's or man's appearance, but because women and men move
their head differently when being spoken to. "If a person appears to be a
woman but moves like a man, others will respond with movements similar to
those made when speaking to a man," the researchers say. "This exciting new
technology allows us to manipulate faces in this way for the first time."
