MindJob writes "Berkeley's Sensor & Actuator Center has developed a virtual keyboard that allows you to glue 10 tiny chips to your fingernails and type away anywhere. The chips are composed of tiny, battery powered MEMS, or Microelectromechanical Systems, that work by tracking the location of your fingers and transmitting via a low-powered radio to a nearby receiver that will work regardless of the computer platform."
