3D显示器正在冲击大众市场。它们集成在消费类电视、笔记本电脑和移动的手机中，主要用于虚拟现实和视频内容。我们看到了将深度用于结构化信息的巨大潜力。我们的具体用例是集成在汽车中的3D显示器。这种显示器的能力可以用于以快速且易于理解的方式向驾驶员呈现相关信息，例如，通过基于功能的聚类。然而，过度的放松会导致不适，进而对主要驾驶任务产生负面影响。这需要合理选择视差边界。本文的贡献是双重的。首先，我们识别感知3D内容时的舒适区。其次，我们确定对象之间的最小深度距离，该距离仍然使用户能够快速准确地分离两个深度平面。结果表明，就任务完成时间而言，距离屏幕平面的最佳距离是屏幕平面后面高达35.9弧分的角差。物体之间的角度差异的至少2.7弧分的距离显著减少了层分离的时间。根据结果，我们得出的设计影响。
3D displays are hitting the mass market. They are integrated in consumer TVs, notebooks, and mobile phones and are mainly used for virtual reality as well as video content. We see large potential in using depth also for structuring information. Our specific use case is 3D displays integrated in cars. The capabilities of such displays could be used to present relevant information to the driver in a fast and easy-to-understand way, e.g., by functionality-based clustering. However, excessive parallaxes can cause discomfort and in turn negatively influence the primary driving task. This requires a reasonable choice of parallax boundaries. The contribution of this paper is twofold. First, we identify the comfort zone when perceiving 3D content. Second, we determine a minimum depth distance between objects that still enables users to quickly and accurately separate the two depth planes. The results yield that in terms of task completion time the optimum distance from screen level is up to 35.9 arc-min angular disparity behind the screen plane. A distance of at least 2.7 arc-min difference in angular disparity between the objects significantly decreases time for layer separation. Based on the results we derive design implications.
