有资料表明，自然光条件和真实世界背景会影响光学透视增强现实（AR）显示器在户外环境中的可用性。在许多情况下，室外环境条件会极大地改变用户对用户界面元素的色彩感知，例如冲淡文本或图标的颜色。因此，用户对界面元素的语义解释可能会受到影响，使界面设计变得无用或适得其反--这在色彩编码至关重要的应用领域（如军事或医疗可视化）是一个尤为关键的问题。在本文中，我们介绍了设计和构建光学 AR 测试平台的经验，该测试平台可模拟室外照明条件，并允许我们测量通过光学透视显示器投射的真实世界背景和虚拟色彩的组合颜色。我们介绍了 AR 中色彩混合的形式化，这为进一步研究 AR 显示屏中的感知色彩提供了支持。我们描述了一项工程研究，在这项研究中，我们测量了在系统变化的虚拟和现实条件下到达光学透视显示器用户眼睛的光的颜色。我们的研究结果进一步量化了光照和背景颜色对虚拟图形颜色的影响，并具体量化了虚拟颜色在不同真实世界背景下的变化情况。
It is well-documented that natural lighting conditions and real-world backgrounds affect the usability of optical see-through augmented reality (AR) displays in outdoor environments. In many cases, outdoor environmental conditions can dramatically alter users' color perception of user interface elements, by for example, washing out text or icon colors. As a result, users' semantic interpretation of interface elements can be compromised, rendering interface designs useless or counter-productive — an especially critical problem in application domains where color encoding is critical, such as military or medical visualization. In this paper, we present our experiences designing and constructing an optical AR testbed that emulates outdoor lighting conditions and allows us to measure the combined color of real-world backgrounds and virtual colors as projected through an optical see-through display. We present a formalization of color blending in AR, which supports further research on perceived color in AR displays. We describe an engineering study where we measure the color of light that reaches an optical see-through display user's eye under systematically varied virtual and real-world conditions. Our results further quantify the effect of lighting and background color on the color of virtual graphics, and specifically quantify how virtual colors change based on different real-world backgrounds.
