DECISION UNDER STRESS TRAINING

DUST is a low-cost tool to help practice controlled responses to threatening situations.

People are often more impulsive and less deliberate when in stressful contexts, this is especially problematic for police officers. 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.
