Design a multi touch pad in 15 min



I love this type of video tutorial. Here is a tutorial on how to make your own multi touch pad in 15 minutes using a web cam, cardboard box, a piece of glass and software. I think some regular ambient light is needed! Also the next step, not the least difficult, is to have the software running. The idea is when you place you fingers on the surface, you create shadows with your fingers. The webcam detects these shadows, sends the image to the tracking software to track the shadows as they move around.

Below are some basic info to start:

Materials

* Cardboard Box
* Piece of Clear Flat Sturdy Material (ie. Glass, acrylic, plexiglas)
* Paper (ie. printer paper, tracing paper, almost any paper)
* Webcam or Video Camera
* Computer
* Optional Picture Frame

Finger Tracking Software

* Touchlib Beta v2: - Written by David Wallen
* Download, unzip and copy the config.xml into your touchlib directory
