Crane-related accidents often occur due to failure in timely and accurate hazard identification. Virtual Reality (VR) technology facilitates immersive environments for improving hazard identification without real-world consequences. However, the impact of simulation fidelity on hazard identification performance, particularly for novice crane operators, remains underexplored. This paper examines how simulation fidelity and task complexity affect hazard identification performance among novice operators through a VR experiment with two fidelity and two complexity levels. Findings demonstrate high-fidelity (HF) scenarios significantly improve hazard identification success rate and speed for swing-over hazards but extend task completion times. Task complexity modulates simulation fidelity's impact on task completion, with significant differences between fidelity levels observed only under low complexity. These insights inform the design and calibration of simulation fidelity in VR platforms, potentially improving training efficacy and crane lifting safety for novice operators.

仿真保真度对起重机新手操作员在虚拟环境中识别摇摆危险的影响


由于未能及时、准确地识别危险因素，经常发生起重机相关事故。虚拟现实 (VR) 技术有助于营造沉浸式环境，从而改善危险识别，而不会产生现实世界的后果。然而，模拟保真度对危险识别性能的影响，特别是对于新手起重机操作员来说，仍然没有得到充分研究。本文通过具有两个保真度和两个复杂度级别的 VR 实验，研究了模拟保真度和任务复杂性如何影响新手操作员的危险识别性能。研究结果表明，高保真 (HF) 场景可显着提高危险识别成功率和翻转危险的速度，但会延长任务完成时间。任务复杂性调节模拟保真度对任务完成的影响，仅在低复杂度下观察到保真度水平之间存在显着差异。这些见解可为 VR 平台中模拟保真度的设计和校准提供信息，从而有可能提高新手操作员的培训效率和起重机起重安全性。
