我们提出了一个模块化的变形界面原型曲面。每个曲面造型模块都代表一个可变曲率的边，当与其他模块连接在一起时，设计人员可以交互地构建曲面并调整其曲率。ABS形状模块使用主动和被动形状记忆材料改变其曲率：嵌入式形状记忆合金（SMA）线在加热时增加曲率，而弹性材料在SMA线冷却时恢复扁平形状。每个模块上的霍尔效应传感器允许用户通过调整手的距离来改变曲率。此外，WEBSforms提供了跨多个模块的功能，如“保存”，“重置”和“加载”，以促进设计探索。由于每个模块都是独立的，可以单独控制，因此CIBSform模块可以很好地扩展，并且可以连接到代表各种几何形状的大型曲线网络中。通过给出不同的CIBSforms组件的例子，我们展示了CIBSforms的模块化及其集成的计算支持，使设计师能够在一个单一的集成设计过程中快速探索不同版本的形状。
We present NURBSforms: a modular shape-changing interface for prototyping curved surfaces. Each NURBSform module represents an edge of variable curvature that, when joined together with other modules, enables designers to construct surfaces and adjust their curvature interactively. NURBSform modules vary their curvature using active and passive shape memory materials: an embedded shape memory alloy (SMA) wire increases the curvature when heated, while an elastic material recovers the flat shape when the SMA wire cools down. A hall effect sensor on each module allows users to vary the curvature by adjusting the distance of their hand. In addition, NURBSforms provides functions across multiple modules, such as 'save', 'reset', and 'load', to facilitate design exploration. Since each module is self-contained and individually controllable, NURBSform modules scale well and can be connected into large networks of curves representing various geometries. By giving examples of different NURBSforms assemblies, we demonstrate how the modularity of NURBSforms, together with its integrated computational support, enables designers to quickly explore different versions of a shape in a single integrated design process.
