多显示器环境和智能会议室现在变得越来越常见。这些环境通过各种设备构建共享的显示空间：平板电脑、投影面、桌面和传统显示器。由于不同的显示表面通常不被组织在单个平面中，因此用于将显示缝合在一起的传统方案可能会导致交互问题。然而，有一种更自然的方式来组合显示空间--使用透视图。在本文中，我们开发了基于用户对房间的视角的多显示环境的交互技术。我们设计了透视光标，这是光标到显示空间的映射，从用户所在的位置看起来自然而合乎逻辑。我们进行了一项实验，以比较两种基于透视的技术，即透视光标和基于光束的技术，与传统的拼接显示。我们发现，这两种透视技术在定位任务时都比传统技术快得多，而透视光标是最受欢迎的方法。我们的结果表明，将透视图整合到多显示环境的设计中可以显著提高性能。
Multi-display environments and smart meeting rooms are now becoming more common. These environments build a shared display space from variety of devices: tablets, projected surfaces, tabletops, and traditional monitors. Since the different display surfaces are usually not organized in a single plane, traditional schemes for stitching the displays together can cause problems for interaction. However, there is a more natural way to compose display space -- using perspective. In this paper, we develop interaction techniques for multi-display environments that are based on the user's perspective on the room. We designed the Perspective Cursor, a mapping of cursor to display space that appears natural and logical from wherever the user is located. We conducted an experiment to compare two perspective-based techniques, the Perspective Cursor and a beam-based technique, with traditional stitched displays. We found that both perspective techniques were significantly faster for targeting tasks than the traditional technique, and that Perspective Cursor was the most preferred method. Our results show that integrating perspective into the design of multi-display environments can substantially improve performance.
