A visual experiment using a beam-splitter-based optical see-through augmented reality (OST-AR) setup tested the effect of the size and alignment of AR overlays with a brightness-matching task using physical cubes. Results indicate that more luminance is required when AR overlays are oversized with respect to the cubes, showing that observers discount the AR overlay to a greater extent when it is more obviously a transparent layer. This is not explained by conventional color appearance modeling but supports an AR-specific model based on foreground-background discounting. The findings and model will help determine parameters for creating convincing AR manipulation of real-world objects.

光学透视增强现实中的亮度匹配

使用基于分束器的光学透视增强现实（OST-AR）设置进行的视觉实验测试了AR覆盖层的尺寸和对齐效果，并使用物理立方体进行了亮度匹配任务。结果表明，当AR覆盖层相对于立方体过大时，需要更多的亮度，这表明观察者在AR覆盖层更明显为透明层时会更大程度地折衷。传统的颜色外观建模没有对此进行解释，但是支持基于前景-背景折现的特定于AR的模型。研究结果和模型将有助于确定用于创建令人信服的现实世界对象的AR操作的参数。
