球体是一种多用户、多触摸敏感的球形显示器，其中用于触摸传感的红外摄像头与用于显示器的投影仪共享相同的光路。这种新颖的配置允许：(1)将投影和传感机构都封闭在设备的底部，以及(2)多个用户可以方便地360度访问，具有高度的互动性，没有阴影或遮挡。除了硬件和软件解决方案外，我们还提供了一套多点触摸交互技术和界面概念，以促进围绕Sphere的协作交互。我们设计了四个球形应用程序概念，并报告了从我们在三个高流量位置的初始安装开始的协作活动的几个重要观察结果。
Sphere is a multi-user, multi-touch-sensitive spherical display in which an infrared camera used for touch sensing shares the same optical path with the projector used for the display. This novel configuration permits: (1) the enclosure of both the projection and the sensing mechanism in the base of the device, and (2) easy 360-degree access for multiple users, with a high degree of interactivity without shadowing or occlusion. In addition to the hardware and software solution, we present a set of multi-touch interaction techniques and interface concepts that facilitate collaborative interactions around Sphere. We designed four spherical application concepts and report on several important observations of collaborative activity from our initial Sphere installation in three high-traffic locations.
