在室外增强现实(AR)设置中呈现增强信息的挑战在于可能存在的广泛的不可控环境条件，特别是自然光照的大范围波动以及场景中可能的背景或对象的广泛变化。在本文中，我们提出了一种主动AR试验台，它采样用户的视野，并收集参与者所在位置的室外照度值。本文提出的主要贡献是一项基于用户的研究(使用试验床进行)，该研究考察了四种室外背景纹理、四种文本颜色、三种文本绘制样式和两种文本绘制样式算法对用户性能的影响，该算法用于使用光学、透明AR系统的文本识别任务。我们报告了所有这些变量的显著影响，并讨论了设计指南和未来工作的想法
A challenge in presenting augmenting information in outdoor augmented reality (AR) settings lies in the broad range of uncontrollable environmental conditions that may be present, specifically large-scale fluctuations in natural lighting and wide variations in likely backgrounds or objects in the scene. In this paper, we present a active AR testbed that samples the user's field of view, and collects outdoor illuminance values at the participant's position. The main contribution presented herein is a user-based study (conducted using the testbed) that examined the effects on user performance of four outdoor background textures, four text colors, three text drawing styles, and two text drawing style algorithms for a text identification task using an optical, see-through AR system. We report significant effects for all these variables, and discuss design guidelines and ideas for future work
