Abstract

In order to be able to perceive and recognize objects or surface properties of objects, one must be able to resolve the features. These perceptual tasks can be difficult for both graphical representations and real objects in augmented reality (AR) displays. This paper presents the results of objective measurements and two user studies. The first evaluation explores visual acuity and contrast sensitivity; the second explores color perception. Both experiments test users' capabilities with their natural vision against their capabilities using commercially-available AR displays. The limited graphical resolution, reduced brightness, and uncontrollable visual context of the merged environment demonstrably reduce users' visual capabilities. The paper concludes by discussing the implications for display design and AR applications, as well as outlining possible extensions to the current studies.
使用增强现实显示器的视觉能力的量化
为了能够感知和识别物体或物体的表面属性,必须能够解析特征。这些感知任务对于增强现实(AR)显示中的图形表示和真实对象来说都是困难的。本文介绍了客观测量和两个用户研究的结果。第一次评估考察视觉敏锐度和对比敏感度;第二个是探索颜色感知。这两个实验都测试了用户使用自然视觉的能力和使用商用AR显示器的能力。有限的图形分辨率、降低的亮度和合并环境中不可控的视觉环境明显降低了用户的视觉能力。论文最后讨论了对显示设计和AR应用的影响,并概述了当前研究的可能扩展。
