Decision Under Stress Training
People are often more impulsive and less deliberate when in stressful contexts, this is especially problematic for police officers. I was asked to create a low-cost tool to help practice controlled responses to threatening situations.
DUST uses a custom controller that measures diaphragm expansion to sense breathing and heart rate variability (HRV). This information about their physiological state is fed back to the player as a restriction of the visual field and a variety of other audio/visual cues.
Inside a controllable yet stress inducing context like a zombie shooter, DUST proved effective at both training the physiological control of police trainers in a stressful context and also extracting meaningful behavioral metrics.
