N-Vision是探索包含任意数量变量的函数的n维世界的试验台。虽然我们的交互设备和显示硬件本质上是3D的，但我们演示了如何使用它们来支持与这些高维对象的交互。我们引入了一种为系统开发的新的交互隐喻，我们称之为“世界中的世界”：允许用户查看和操作功能的嵌套异类坐标系。我们世界中的物体可以用一套工具来探索。我们在“金融可视化”中描述了一个示例n-Vision应用程序，其中的功能是金融工具的模型。N-Vision的软件架构支持任意转换的嵌套框的层次结构，这些框定义了一个交互空间，在其中显示信息和获取输入。我们的设计部分模仿了X Window系统的分层2D窗口，旨在提供一个非常适合使用真3D输入和立体显示设备的环境。框与支持3D运动、进入和离开事件的事件处理程序相关联，并提供手指手势识别。Cr
n-Vision is a testbed for exploring n-dimensional worlds containing functions of an arbitrary number of variables. Although our interaction devices and display hardware are inherently 3D, we demonstrate how they can be used to support interaction with these higher-dimensional objects. We introduce a new interaction metaphor developed for the system, which we call “worlds within worlds”: nested heterogeneous coordinate systems that allow the user to view and manipulate functions. Objects in our world may be explored with a set of tools. We describe an example n-Vision application in “financial visualization,” where the functions are models of financial instruments. n-Vision’s software architecture supports a hierarchy of arbitrarily transformed, nested boxes that defines an interactive space within which information is displayed and input obtained. Our design, modeled in part after the hierarchical 2D windows of the X Window System, is intended to provide an environment that is well suited to the use of true 3D input and stereo display devices. Boxes are associated with event handlers that support 3D motion, enter, and leave events, and provide recognition of finger gestures. CR
