PINTER is a narrative generation system that uses users’ passive physiological reactions to a medical drama to adapt the unfolding narrative. The user watches a medical drama, and their physical responses are recorded by the system, which then adjusts the narrative focus, pacing, and character relationships.
‘An inner narrative control loop incrementally selects actions for the narrative based on the current actions, goal and state of the narrative world. They are visualized using 3D graphics and the state of the world updated to reflect the result of visualization. The users’ physiological responses to the visualized narrative, measured using EMG and GSR, are fed back to the module controlling narrative generation. Positive (negative) EMG response indicates user preference (dislike) for certain actions while GSR response triggers’ change to the current state of the tension level.’
