I honestly don't know how to accurately describe Disney Research's new touch-based controller technology. Very dedicated scientists and engineers recently developed an interface that monitors plants and picks up on human fingers when they make contact with stems and petals. The working name is Botanicus Interacticus, and someday your average flowering plant could turn into a viable game controller.
I guess the weirdest part of this is realizing that Disney has its fingers in many technological research and development pies. I want to see this as part of a game. Perhaps not a truly dedicated controller, but as a curious and experimental offshoot to something involving beanstalks and orchids.
