增强现实（AR）的用户必须将他们的注意力转向真实的世界以及人工信息。作者研究了两种信息源之间的干扰对完成视觉搜索任务的影响。搜索任务在3种不同的条件下进行，其中2种在移动的系统中的AR中发现。参与者被要求检测叠加在背景上的目标。目标和背景被呈现在一个55 ° × 43 °（水平×垂直）的矩形区域上。目标出现在屏幕上的六个不同位置。一段汽车驾驶的录像作为背景。在1种情况下，连续重放记录。记录的静态图像以5秒的间隔采样，并在另一条件下作为背景重放。一个统一的灰色背景作为基线。
Users of augmented reality (AR) must direct their attention toward real world as well as artificial information. The authors investigated some aspects of interference between the 2 sources of information that affect performance in completing a visual search task. The search task was carried out under 3 different conditions, 2 of them as found in AR in mobile systems. Participants were asked to detect a target that was superimposed on a background. Target and background were presented on a screen subtending a rectangular area of 55� � 43� (horizontal � vertical). The target appeared at 6 different locations on the screen. A video recording of a car drive served as the background. In 1 condition, the recording was replayed continuously. Static images of the record were sampled at 5-sec intervals and replayed as background in another condition. A uniform gray background served as a baseline.
