Proxemics, nonverbal communication, peripersonal space and physical touch in Human-Robot Interaction

Humans use a variety of nonverbal behavioral cues to communicate intent and
ensure efficient cooperation with other humans while being engaged in
collaborative tasks that require close physical interaction. These behaviors
include conscious movements, such as informative eye gaze, gestures and touch,
but also unconscious movements, such as mutual gaze, blinking and body
posturing. Besides these active behaviors also more passive factors like the
perception of peripersonal space and proxemics play a very important role during
these types of social exchanges. Humans are very sensitive to the intrusion of
others into their different personal spatial zones. The most intimate of these
personal spatial zones is actual physical touch. When and how physical touch is
appropriate during a social interaction depends on a variety of factors, among
which cultural background, level of familiarity and the gender of the
interaction partner are the most prominent. Since robots will work more and more
in close physical proximity with humans in different contexts, it is important
to take the factors that shape social human interaction into consideration when
designing behaviors for robots, in order to ensure an efficient, intuitive and
comfortable interaction between humans and robots.
Following this line thought, in the first part of this talk research concerned
with the design of different nonverbal interaction behaviors for robots will be
discussed, i.e. work on mutual gaze and blinking on the iCub robot, and on
contagious yawning on the EMYS robot. In the second part we will give an outlook
on the upcoming proxemics and physical touch research with the NAO robot with
tactile sensors at the Department of Cybernetics, FEE, CTU Prague.
