      abstract     = {To navigate the social world, humans heavily rely on gaze
                      for non-verbal communication as it conveys information in a
                      highly dynamic and complex, yet concise manner: For
                      instance, humans utilize gaze effortlessly to direct and
                      infer the attention of a possible interaction partner. Many
                      traditional paradigms in social gaze research though rely on
                      static ways of assessing gaze interaction, e.g., by using
                      images or prerecorded videos as stimulus material. Emerging
                      gaze contingent paradigms, in which algorithmically
                      controlled virtual characters can respond flexibly to the
                      gaze behavior of humans, provide high ecological validity.
                      Ideally, these are based on models of human behavior which
                      allow for precise, parameterized characterization of
                      behavior, and should include variable interactive settings
                      and different communicative states of the interacting
                      agents. The present study provides a complete definition and
                      empirical description of a behavioral parameter space of
                      human gaze behavior in extended gaze encounters. To this
                      end, we (i) modeled a shared 2D virtual environment on a
                      computer screen in which a human could interact via gaze
                      with an agent and simultaneously presented objects to create
                      instances of joint attention and (ii) determined
                      quantitatively the free model parameters (temporal and
                      probabilistic) of behavior within this environment to
                      provide a first complete, detailed description of the
                      behavioral parameter space governing joint attention. This
                      knowledge is essential to enable the modeling of interacting
                      agents with a high degree of ecological validity, be it for
                      cognitive studies or applications in human-robot
                      interaction.},
