How to build a Multi-Touch surface

Step 1 What is a Multi-Touch surface?

 A Multi-Touch surface is essentially a giant touch screen that can process multiple touches at once.  And in our case, a virtually unlimited amount of touches.  By allowing multiple touches, gestures can be performed on surface.  These gestures are typically simple things like pinching and pulling on an image to zoom in and out.  By supporting gestures like these interfacing with a computer becomes much more intuitive and fun.  In a public place, a Multi-Touch surface can be a real attention grabber.
