Get ready to 'spray' touch controls onto any surface
Nowadays we're accustomed to the slick glass touchscreens on our phones and tablets, but what if we could extend such luxury to other parts of our devices -- or to any surface, for that matter -- in a cheap and cheerful way? Well, apparently there's a solution on the way. At the ACM CHI conference this week, Carnegie Mellon University's Future Interfaces Group showed off its latest research project, dubbed Electrick, which enables low-cost touch sensing on pretty much any object with a conductive surface -- either it's made out of a conductive material (including plastics mixed with conductive particles) or has a conductive coating (such as a carbon conductive spray paint) applied over it. Better yet, this technique works on irregular surfaces as well.
