引导观众注意力的能力在计算机图形学、数据可视化、图像分析和训练中有重要的应用。现有的基于计算机的注视操纵技术，其引导观众的注意力关于显示器，已经被证明是有效的空间学习，搜索任务完成，和医疗培训应用。在这项工作中，我们扩展了数字图像以外的凝视操纵的概念，包括控制，现实世界的环境。我们解决两个主要的挑战，在引导注意现实世界中的对象：确定什么对象的观众目前正在关注，并提供（投影）的视觉提示的场景的不同部分，以吸引观众的注意力。我们的系统包括一对眼睛跟踪眼镜，以确定观众的视线位置，和一个投影仪，以创建在物理环境中的视觉提示。用户研究的结果表明，我们可以有效地引导观众的目光在现实世界的场景。我们的技术适用于广泛的教学环境，包括飞行员培训和驾驶模拟器。
The ability to direct a viewer's attention has important applications in computer graphics, data visualization, image analysis, and training. Existing computer-based gaze manipulation techniques, which direct a viewer's attention about a display, have been shown to be effective for spatial learning, search task completion, and medical training applications. In this work we extend the concept of gaze manipulation beyond digital imagery to include controlled, real-world environments. We address two main challenges in guiding attention to real-world objects: determining what object the viewer is currently paying attention to, and providing (projecting) a visual cue on a different part of the scene in order to draw the viewer's attention there. Our system consists of a pair of eye-tracking glasses to determine the viewer's gaze location, and a projector to create the visual cue in the physical environment. The results of a user study show that we can effectively direct the viewer's gaze in the real-world scene. Our technique has applicability in a wide range of instructional environments, including pilot training and driving simulators.
