Tutorial 4: Build Your Own Multi-Touch Pad


Anne Roudaut


Sunday November 7th, 15:30-17:00


We will show you how to build your own (stylish) USB FTIR multitouch input pad using inexpensive off-the-shelf components. You will (1) bend the acrylic waveguide to make it function as a stand (also adds style-looks great when it lights up). You will (2) solder components to make a USB LED light that injects light into the acrylic from the side. And you will (3) connect a USB camera that observes the contact area from below and transmits the video image to a connected computer. This tutorial gives you the opportunity to understand the principles of FTIR but also to play with heat guns, soldering irons, lights and acrylic. A preview of what you could build and bring back home at
