- Abstract
- This dissertation presents a line of research
that investigates the information people use to pursue and evade other
pedestrians and to perceive whether other pedestrians are pursuing or
evading. Three experiments were conducted in the Virtual Environment
Navigation Laboratory (VENLab), a large ambulatory virtual environment.
Experiment 1 presents a dynamical systems description of human pursuit
and evasion that uses the constant bearing strategy. The steering
dynamics model developed by Warren and colleagues (Fajen & Warren,
2003; 2007; Cohen, Bruggeman, & Warren, under review) is shown to
extend to pursuit-evasion interactions. Experiment 2 investigates
whether the information provided by a pedestrian's contingent movement,
trajectory, and head fixation specifies pursuit and evasion behavior. In
this study participants interacted with a virtual avatar driven by the
steering dynamics model in an immersive virtual environment. Pursuit is
specified by contingent motion that preserves a constant bearing angle,
and evasion is specified by movement that avoids a constant bearing
angle. In addition the approach trajectory of an evading avatar is shown
to effect the perception of evasion, and head fixation increases
participants' sensitivity to pursuit and evasion when an avatar is
presented at a close distance. Experiment 3 tests whether the behavior
of multiple pedestrians is perceived sequentially or if pursuit behavior
'pops out' in a crowd. Participants were instructed to identify a
pursuing avatar in the presence of one, two, or three evading (i.e.
distracter) avatars. The data support a sequential perception of
pedestrian movement. Overall the results of this dissertation provide an
information-based account of pedestrian pursuit-evasion
interactions.
