        for (int i = 0; i < timeline.Length; i++)
        {
            yield return new WaitForSeconds(timeline[i]);
            TriggerHazard(haptics, scenarios[i].hazard);

5. Measured Outcomes

Global Manufacturing Study (2024):

• 83% better hazard recognition vs. video training
• 5.7x more memorable than classroom instruction
• 91% of workers prefer XR to traditional methods
• 62% reduction in recordable incidents post-training

ROI Calculation Example:

def safety_training_roi(incident_cost, training_hours):
    traditional_cost = 40 * training_hours * 25  # Instructor+facility
    xr_cost = 15000 + (5 * training_hours * 25)  # Hardware+refresh

    incident_reduction = 0.62 * incident_cost
    productivity_gain = 0.3 * training_hours * 75  # 30% faster

    annual_savings = incident_reduction + productivity_gain
    return (annual_savings - xr_cost) / xr_cost  # ROI ratio
