The project, nicknamed Botanicus Interactus, works when a wire is placed in the soil of a plant (either real or artificial). The technology monitors the plant, and can detect when something touches it. An electronic display can relay that information back, or it could work with another device like an iPod, turning on when a certain motion is detected. It's built with the same sort of technology as the ubiquitous touchscreen, but works on multiple frequencies, instead of the usual single frequency. With that, it can pick up where it's being touched and how hard.
