物理按钮具有独特的能力，通过直观的触觉线索提供低注意力和无视觉的交互。不幸的是，这些界面的物理特性使它们成为静态的，限制了它们所能支持的用户界面的数量和类型。另一方面，触摸屏技术提供了最终的界面灵活性，但没有提供固有的触觉质量。在本文中，我们描述了一种旨在占据这两个极端之间空间的技术-提供触摸屏的一些灵活性，同时保留物理界面的有益触觉特性。我们研究的结果是一个包含可变形区域的视觉显示，能够产生物理按钮和其他界面元素。这些触觉特征可以动态地进出界面，或者在程序控制下进行操作。我们描述的表面提供了视觉显示的全部动态（通过后投影）以及允许多点触摸输入（通过显示器后面的红外照明和摄像头设置）。为了说明表面的触觉能力，我们描述了我们在探索和原型设计中发现的一些变化。这些不仅仅是简单的开/关驱动，而且可以组合起来提供一系列不同的可能的触觉表达。一项初步的用户研究表明，我们的动态按钮在触觉搜索任务中的表现与物理按钮非常相似。
Physical buttons have the unique ability to provide low-attention and vision-free interactions through their intuitive tactile clues. Unfortunately, the physicality of these interfaces makes them static, limiting the number and types of user interfaces they can support. On the other hand, touch screen technologies provide the ultimate interface flexibility, but offer no inherent tactile qualities. In this paper, we describe a technique that seeks to occupy the space between these two extremes - offering some of the flexibility of touch screens, while retaining the beneficial tactile properties of physical interfaces. The outcome of our investigations is a visual display that contains deformable areas, able to produce physical buttons and other interface elements. These tactile features can be dynamically brought into and out of the interface, and otherwise manipulated under program control. The surfaces we describe provide the full dynamics of a visual display (through rear projection) as well as allowing for multitouch input (though an infrared lighting and camera setup behind the display). To illustrate the tactile capabilities of the surfaces, we describe a number of variations we uncovered in our exploration and prototyping. These go beyond simple on/off actuation and can be combined to provide a range of different possible tactile expressions. A preliminary user study indicates that our dynamic buttons perform much like physical buttons in tactile search tasks.
