SchrodingerZ writes "Designers of Disney Research in Pittsburgh Pa, have turned the average household plant into a musical device and remote control. Called the Botanicus Interacticus project, this new program can turn any household plant into touch-sensitive computer system. 'The system is built upon capacitive touch sensing — the principle used on touchscreens in smartphones and tablets — but instead of sensing electrical signals at a single frequency, it monitors capacitive signals across a broad range of frequencies. It's called Swept Frequency Capacitive Sensing.' This works by putting a pulsating electrode into the soil around a plant, which excites the plant, making any touch to the parts of the plant a replayable signal. This could mean soon swatting at your household plant could change the television channel or turn up the volume (PDF)."
