Second, a multiplayer experiment is implemented in VR to reveal microscopic phenomena about how these technologies affect the behaviors and decision-making of emergency participants. The results demonstrate that real-time navigation and information sharing help most emergency participants avoid being lost, stay away from the danger, enable proactive rescue, and reduce response time.

This study examines Jiangdong Village in Ruoergai County, Sichuan Province, using a human-centered dynamic accessibility measurement approach to assess the impact of high-altitude environments on evacuation efficiency through psychological-physiological data analysis. By analyzing evacuation data from 77 villagers, we constructed a multiple linear regression model (R<sup>2</sup> = 0.846), which revealed a significant positive correlation between age and evacuation time (regression coefficient 0.93, P = 0.006). Younger participants exhibited better physiological adaptability (mean heart rate 106.07 bpm at 50s), whereas older individuals showed a slower heart rate response (mean heart rate 74.14 bpm at 50s) and delayed recovery. Psychological stress was also significantly correlated with evacuation time (correlation coefficient 0.64, P < 0.001), with high-stress individuals evacuating in 229.33s on average, compared to 142.89s for low-stress participants. The findings indicate that psychological stress and heart rate dynamics are key factors influencing evacuation efficiency.
