You're missing the point. Currently capacitive touch interfaces require a grid of copper and an MCU. This new technique lets you add the interface to any object that will take a thin film spray, which is great! The same issues with false positive rejection from humidity and moisture and radio noise exist, but now we can add it to arbitrary objects like handles and such without busting ourselves integrating the copper loops into whatever device it is we're building. You can just spray the surface, calibrate, and go. Lots of great design space here.
