在增强现实(AR)中,户外任务的搜索性能是评估大量AR应用成功与否的重要指标。用户必须能够快速找到内容,标签和指示符不能是侵入性的,但仍然可以清楚地看到,用户界面应该在各种条件下最大限度地提高搜索性能。为了解决这些问题,我们已经建立了一系列的实验,以测试虚拟特性,如颜色,大小和领导线上的搜索任务和搜索在真实的和模拟环境中的性能的影响。我们评估两个主要领域,包括1)外围视野(FOV)的限制和标签技术的影响,在户外移动的搜索目标采集,2)的影响,如颜色,大小和运动的本地特性,在动态背景上的文本标签。第一个实验表明,有限的FOV将严重限制搜索性能,但在外围适当放置标签和引线可以缓解这个问题,而不会干扰行走或降低用户舒适度。在第二个实验中,我们发现不同类型的运动在光学与视频透视显示器中更明显,但蓝色在两者中最明显。结果可以帮助设计更有效的视图管理技术,特别是更广泛的视野显示。
In Augmented Reality (AR), search performance for outdoor tasks is an important metric for evaluating the success of a large number of AR applications. Users must be able to find content quickly, labels and indicators must not be invasive but still clearly noticeable, and the user interface should maximize search performance in a variety of conditions. To address these issues, we have set up a series of experiments to test the influence of virtual characteristics such as color, size, and leader lines on the performance of search tasks and noticeability in both real and simulated environments. We evaluate two primary areas, including 1) the effects of peripheral field of view (FOV) limitations and labeling techniques on target acquisition during outdoor mobile search, and 2) the influence of local characteristics such as color, size, and motion on text labels over dynamic backgrounds. The first experiment showed that limited FOV will severely limit search performance, but that appropriate placement of labels and leaders within the periphery can alleviate this problem without interfering with walking or decreasing user comfort. In the second experiment, we found that different types of motion are more noticeable in optical versus video see-through displays, but that blue coloration is most noticeable in both. Results can aid in designing more effective view management techniques, especially for wider field of view displays.
