This report describes the design and functionality of version 0.2 of the Graph-theoretic Interactive Narrative Gin System, a system intended to increase interactivity of virtual reality environments VEs used for human experimentation, while still allowing for necessary experimental constraints to be enforced so that the data can be analyzed. An initial step towards increasing interactivity is to allow human subjects to control their own navigation through the VE. In order to make this initial step, the Gin system uses the graph theory to model the topography of the VE in an abstract fashion monitor the movement of subjects through the environment and add, move, activate, deactivate, andor remove experimental stimuli so that the experimental subjects are exposed to the stimuli in the way that the experiment designer intends for them to be. In the long term, the goal of the Gin system is to represent both a environmental topography and experimental context graph, allowing for both increased tractability of experimental scenario development, and increased tractability of experimental data analysis.
