• Description:
  This study applies engineering anthropometry and Monte Carlo simulations to define ergonomic guidelines for minimizing vergence-accommodation conflict in virtual environments. Interpupillary distance (IPD) data from three anthropometric datasets (ANSUR I, ANSUR II, CAESAR) were bootstrapped to determine conservative viewing-distance limits accommodating 99% of users. Simulations considered various IPD calibration errors, fixed IPD settings, and focal distances typical of commercial displays. Results established practical zones of comfortable disparity (ZoCD) and vergence to guide virtual interface design. Description provided by NIOSH
