Query: Hacking Nonverbal Communication Between Pedestrians and Vehicles in
  Virtual Reality   We use an immersive virtual reality environment to explore the intricate
social cues that underlie non-verbal communication involved in a pedestrian's
crossing decision. We "hack" non-verbal communication between pedestrian and
vehicle by engineering a set of 15 vehicle trajectories, some of which follow
social conventions and some that break them. By subverting social expectations
of vehicle behavior we show that pedestrians may use vehicle kinematics to
infer social intentions and not merely as the state of a moving object. We
investigate human behavior in this virtual world by conducting a study of 22
subjects, with each subject experiencing and responding to each of the
trajectories by moving their body, legs, arms, and head in both the physical
and the virtual world. Both quantitative and qualitative responses are
collected and analyzed, showing that, in fact, social cues can be engineered
through vehicle trajectory manipulation. In addition, we demonstrate that
immersive virtual worlds which allow the pedestrian to move around freely,
provide a powerful way to understand both the mechanisms of human perception
and the social signaling involved in pedestrian-vehicle interaction.
