单显示器群件（SDG）支持面对面的协作者在单个共享显示器上工作，其中所有人都有自己的输入设备。尽管SDG的概念很简单，但在如何管理SDG内部的互动方面存在着令人惊讶的许多问题。其中一个问题是潜在的干扰，一个人可以提高一个界面组件（如菜单或对话框）的方式，阻碍另一个人正在做什么，即通过模糊另一个人的工作区域，正好是下面的凸起组件。我们提出透明界面组件作为一种可能的干扰解决方案：当一个人可以举起组件并与之交互时，其他人可以看穿它并继续在它下面工作。为了测试这个概念，我们首先使用不透明和透明的SDG菜单实现了一个简单的SDG游戏。通过一个对照实验，我们分析了干扰如何影响人们在不透明和透明菜单条件下的表现：一个单独的条件（一个人单独玩）作为我们的控制。我们的研究结果表明，透明菜单确实减少了干扰的影响，而且SDG玩家压倒性地喜欢它而不是不透明菜单。
Single Display Groupware (SDG) supports face-to-face collaborators working over a single shared display, where all people have their own input device. Although SDG is simple in concept, there are surprisingly many problems in how interactions within SDG are managed. One problem is the potential for interference, where one person can raise an interface component (such as a menu or dialog box) in a way that hinders what another person is doing ie, by obscuring another person’s working area that happens to be underneath the raised component. We propose transparent interface components as one possible solution to interference: while one person can raise and interact with the component, others can see through it and can continue to work underneath it. To test this concept, we first implemented a simple SDG game using both opaque and transparent SDG menus. Through a controlled experiment, we then analysed how interference affects peoples’ performance across an opaque and transparent menu condition: a solo condition (where a person played alone) acts as our control. Our results show that the transparent menu did lessen the effect of interference, and that SDG players overwhelmingly preferred it to opaque menus.
