我们介绍了一种新的输入设备，变形，支持2.5D触摸手势，有形的工具，和任意对象通过实时结构光扫描的延展性表面的互动。DeForm通过三相结构光3D扫描仪捕获凝胶表面的高分辨率表面变形和2D灰度纹理。这种技术可以与IR投影相结合，以允许不可见的捕获，从而为可变形表面上的协同定位视觉反馈提供机会。我们描述了跟踪手指，整个手势，和任意有形工具的方法。我们概述了一种方法，用于物理编码的基准标记信息的高度图的有形工具。此外，我们描述了一种新的方法，用于区分人的触摸和有形的工具，通过在输入表面上的电容感测。最后，我们通过一些示例应用程序来激励我们的设备。
We introduce a novel input device, deForm, that supports 2.5D touch gestures, tangible tools, and arbitrary objects through real-time structured light scanning of a malleable surface of interaction. DeForm captures high-resolution surface deformations and 2D grey-scale textures of a gel surface through a three-phase structured light 3D scanner. This technique can be combined with IR projection to allow for invisible capture, providing the opportunity for co-located visual feedback on the deformable surface. We describe methods for tracking fingers, whole hand gestures, and arbitrary tangible tools. We outline a method for physically encoding fiducial marker information in the height map of tangible tools. In addition, we describe a novel method for distinguishing between human touch and tangible tools, through capacitive sensing on top of the input surface. Finally we motivate our device through a number of sample applications.
