Electrick lets you spray touch controls onto any object or surface

The world is full of touchscreens these days, but most of them are on flat, smooth surfaces made of glass. Now researchers at Carnegie Mellon University have come up with a way to add touch controls to any object, no matter what shape or material it is. The system is called Electrick, and it uses a software algorithm to read the press of your finger by measuring changes in the flow of electricity across a conductive surface.
Researchers from the Future Interfaces Group showed off a few ideas for
