Patented Gestures Detailed

An anonymous reader writes "Annalee Newitz wrote a fresh/interesting/informative piece on the io9 site about 10 Gestures that are already patented; unsurprisingly by the likes of Apple, Microsoft and Nintendo. But it's the other patent holders on the list that seem more interesting to me: Xerox, Lucent, Palm and lesser known Gesturetek have very broad patents for this tech."
