The social psychologists Fritz Heider and Marianne Simmel have shown in the 1950s that movies about very simple
object interactions are typically interpreted in a very social manner, quickly perceiving motivations and emotions. We have
developed a tool to generate Heider-Simmel-like videos. In contrast to the Heider-Simmel Interactive Theater project by
Andrew Gordon and colleagues, though, our tool enables the generation of story-lines. The user is offered a manifold of
individual object behaviors, such as approaching, avoiding, or circling around another object, and a manifold of perceptual
events, such as the detection of another object, the touch of another object, etc. Behavior-event complexes can be chosen and
concatenated by an intuitive user interface. The resulting story lines are then played-out by the tool in different scenarios,
yielding different videos about socially similar interactions. The tool may be very useful for conducting future social- and
object-interaction-related cognitive science projects.
