While Immersive Virtual Environments (IVEs) are essential for pre-construction investigation of daylight perception in buildings, current daylight studies show limitations in achieving adequate immersion and interaction levels in IVEs, driven by the speed constraints of traditional light simulation tools. Therefore, it is necessary to examine whether using new real-time simulation tools can offer better interaction while maintaining accurate daylight perception. This study validates the accuracy of an interactive method to investigate daylight brightness perception in IVEs, through comparing collective perception visualizations (introduced as Perceptual Light Maps) across reality and an identical IVE based on real-time rendering in a game engine software. The results show strong consistency between perceptions in reality and IVE. The findings accentuate the adequacy of the proposed method as a surrogate to real environments in investigating brightness perception in daylit spaces. Furthermore, they encourage further investigation towards adopting game engines as a validated daylight simulation tool.

虽然沉浸式虚拟环境 (IVE) 对于建筑物中日光感知的施工前调查至关重要，但当前的日光研究表明，由于传统光模拟工具的速度限制，在 IVE 中实现足够的沉浸和交互水平方面存在局限性。因此，有必要检查使用新的实时仿真工具是否可以在保持准确的日光感知的同时提供更好的交互。本研究通过比较现实中的集体感知可视化（称为感知光图）和基于游戏引擎软件中的实时渲染的相同 IVE，验证了研究 IVE 中日光亮度感知的交互式方法的准确性。结果表明现实中的感知和IVE 之间的感知具有很强的一致性。研究结果强调了所提出的方法在研究日光空间中的亮度感知时作为真实环境的替代品的充分性。此外，他们鼓励进一步研究采用游戏引擎作为经过验证的日光模拟工具。
