半透明通过允许一个窗口的内容在其他窗口重叠时保持部分可见，从而增加了界面可以在给定屏幕空间中公开的信息量。我们之前已经探索了全屏幕、半透明视频窗口在协作、分布式软件环境中的应用，以努力将面对面的交流更无缝地融入到集团软件开发中。我们使用该系统的经验表明，尽管半透明视频可以改善分布式协作的各个方面，但也会出现两个问题。首先，来自视频覆盖的像素的Alpha混合可能会混淆某些类型的可视数据，使视频或底层内容难以查看。其次，视频覆盖使在帧缓冲区提供应用程序共享的能力变得复杂--帧缓冲区是最通用的共享层。在本文中，我们提出了克服这些问题的方法。
Semi-transparency increases the amount of information that interfaces can expose in a given screen space by allowing content from a window to remain partially visible while other windows overlap it. We have previously explored the application of a full screen, semi-transparent video window in a collaborative, distributed software environment in an effort to more seamlessly incorporate face-to-face communication into group software development. Our experience with the system suggests that, while semi-transparent video can improve aspects of distributed collaborations, two problems emerge. First, the alpha blending of pixels from video overlays can obfuscate certain types of visual data, making either the video or the underlying content diffcult to see. Second, video overlays complicate the ability to provide application sharing at the framebuffer - the most general sharing layer. In this paper, we present methods to overcome these problems.
