Smart doorknob? How about a smart glass of water?
A doorknob that knows whether to lock or unlock based on how it is grasped, a smartphone that silences itself if the user holds a finger to her lips and a chair that adjusts room lighting based on recognizing if a user is reclining or leaning forward are among the many possible applications of Touché,...Touché is a form of capacitive touch sensing, the same principle underlying the types of touchscreens used in most smartphones. But instead of sensing electrical signals at a single frequency,...This Swept Frequency Capacitive Sensing (SFCS) makes it possible to not only detect a "touch event," but to recognize complex configurations of the hand or body that is doing the touching. An object thus could sense how it is being touched, or might sense the body configuration of the person doing the touching.
Lots of scenarios flower with these body gesture controls, smart doorknob, and smart sofa applications.
Far out. I wish I were living 100 years from now, when I could control all of my human "accessories" with simple gestures. What fun that would be!
