使用什么技术来构建多点触控应用程序？
谁能提供任何细节、代码片段、示例等，说明如何构建像 Obscura Digital 构建的“岩墙”这样酷的东西？

让我们假设我们能够获得所需的任何技术。我从哪里开始？
Can anyone provide any details, code snippets, examples, etc. of how to go about building something as cool as this "Rock Wall" that Obscura Digital built?

Let's just pretend we have access to whatever technology is required. Where do I start?

我对这个问题的理解是，什么样的库可用于多点触控（特别是在 .Net 中）？
如果是这种情况，请参见此处和此处。实际上两者都不需要 Microsoft Surface 桌子，但它确实需要多点触控兼容硬件和 Windows 7。
My understanding of the question is, what kind of libraries are available for multitouch (specifically in .Net)?
If this is the case, see here and here. Neither actually requires a Microsoft Surface table, but it does require multi-touch compatible hardware and Windows 7.

TouchKit：开源多点触摸屏开发人员工具包

您需要一大块有机玻璃、一个红外网络摄像头、一台投影仪、几个红外 LED 和某种半透明材料，如屠夫纸。
红外 LED 沿着玻璃的外边缘放置，并用红外光照亮玻璃。投影仪获取计算机图像并将其投影到安装在玻璃后面的屠夫纸上。当您用手指触摸玻璃时，红外摄像机中就会产生可由计算机处理的图像。
整个装置的建造成本不到 1000 美元。 TouchKit 提供除投影仪以外的所有产品以预组装形式，价格为 1580 美元（含运费）。

You need a large piece of plexiglass, an infrared webcam, a projector, several infrared LED's, and some sort of translucent material like butcher paper.
The infrared LED's are placed along the outer edge of the glass, and illuminate the glass with infrared light. The projector takes the computer image and projects it onto the butcher paper, which is mounted behind the glass. When you touch the glass with your finger, it produces an image in the infrared camera that can be processed by the computer.
The whole thing can be built for less than $1000. TouchKit offers everything but the projector in a pre-assembled form for $1580, including shipping.
