Over the last several decades, designers have used digital screens to view images of real and simulated spaces and make critical design decisions. Screen technology has improved during this time, as technologies like OLED have replaced legacy displays (CRT, plasma, and LCD). These new screens provide a higher pixel resolution, luminous output and contrast ratio. Immersive head-mounted displays now allow designers to view immersive images, and recent developments in real-time rendering have encouraged the uptake of virtual reality (VR) head-mounted displays in mainstream practice and design education. This paper presents an experiment on lighting perception using a series of LED lighting conditions in a real space and a virtual representation of those conditions captured using a 360° head-mounted display camera and presented on an HTC Vive Pro HMD. Fifty-three participants were asked to rate each lighting condition by viewing it in a real space (n = 30) or via immersive HDR photographs displayed in a VR HMD (n = 23). The results show that ratings of visual comfort, pleasantness, evenness, contrast and glare are similar between the HTC Vive Pro HMD and our real space when evaluating well-lit scenes, but significant differences emerge in dim and highly contrasted scenes for a number of rating scales.

在过去的几十年中，设计师使用数字屏幕查看真实和模拟空间的图像并做出重要的设计决策。随着OLED之类的技术取代了传统的显示器（CRT，等离子和LCD），屏幕技术在此期间得到了改善。这些新屏幕可提供更高的像素分辨率，发光输出和对比度。身临其境的头戴式显示器现在允许设计人员查看沉浸式图像，实时渲染的最新发展鼓励在主流实践和设计教育中采用虚拟现实（VR）头戴式显示器。本文介绍了在真实空间中使用一系列LED照明条件进行照明感知的实验，以及使用360°头戴式摄像头捕获并在HTC Vive Pro HMD上呈现的这些条件的虚拟表示。53名参与者被要求通过在真实空间（n = 30）中查看每个照明条件或通过VR HMD中显示的沉浸式HDR照片（n = 23）来对每种照明条件进行评分。结果表明，在评估光线充足的场景时，HTC Vive Pro HMD与我们的真实空间之间的视觉舒适度，愉悦性，均匀性，对比度和眩光相似，但是在许多等级的昏暗和高对比度场景中，都出现了显着差异。
