Instructable: Use Any Surface as a Touch Interface with Arduino


Touché is a new sensing technology that can not only detect a touch event, but simultaneously recognize complex configurations of the human hands and body during touch interaction. Developed by Disney Research Lab, Touché significantly enhances touch interaction in a broad range of applications, from enhancing conventional touchscreens to designing interaction scenarios for unique use contexts and materials. For example, you can add complex touch and gesture sensitivity not only to computing devices and everyday objects, but also to the human body and liquids. I asked my friend DZL if he could design a version that worked on the Arduino platform.



With DZL’s permission, the solution has been packaged as an instructable that can be found here. I have made a simple graphing sketch that enables you to see the data and also do simple gesture recognition. Further, the instructable contains a step-by-step guide on how to build the circuit and upload the code. The only special components is a coil that can be made out of wire wrapped around a toilet paper roll.
