Touché - detecting complex gestures though multifrequency analysis

Great work by Disney Research on detecting gestures by analyzing a large spectrum of frequencies from capacitive sensing.

Touché: Enhancing Touch Interaction on Humans, Screens, Liquids, and Everyday Objects

"Touché proposes a novel Swept Frequency Capacitive Sensing technique that can not only detect a touch event, but also recognize complex configurations of the human hands and body. Such contextual information significantly enhances touch interaction in a broad range of applications, from conventional touchscreens to unique contexts and materials. For example, in our explorations we add touch and gesture sensitivity to the human body and liquids. We demonstrate the rich capabilities of Touché with five example setups from different application domains and conduct experimental studies that show gesture classification accuracies of 99% are achievable with our technology."
