Developers of medical simulators and instructors who use them often have questions about the level of fidelity needed in a simulation. In this article, we address the nature of fidelity with respect to virtual reality training systems. We argue that high-fidelity simulators do not always lead to better performance, and in some instances, can interfere with performance. The primary reason for these seemingly counterintuitive findings lies with a fundamental understanding of how humans perceive and process sensory information. Consequently, simulation-based training systems should be developed to maximize their effectiveness, not their fidelity.
医学模拟器的开发者以及使用这些模拟器的教员常常对模拟所需的逼真度水平存在疑问。在本文中，我们探讨了虚拟现实训练系统的逼真度本质。我们认为，高保真模拟器并不总是能带来更好的表现，在某些情况下，还可能干扰表现。这些看似违反直觉的发现的主要原因在于对人类如何感知和处理感官信息的基本理解。因此，基于模拟的训练系统的开发应旨在最大化其有效性，而非其逼真度。
