The first practical application of this hot technology is not for the dumb door knobs but for tablets. Capacitive sensing has revolutionized tablets and smart phones. However the current technology relies only on capacitive sensing at a single frequency. The group at CMU and Disney Research uses swept frequency capacitive sensing to capture richer interactive data between the hand and the objection being touched. This additional dimension of information greatly enhances the interactive possibilities between hand and the touched object. This technology will bring the intuitive interaction between user and the tablet to a whole new level.
According to the CMU's press release, the researchers will present their findings on May 7 at CHI 2012, the Conference on Human Factors in Computing Systems, in Austin, Texas, where it has been recognized with a prestigious Best Paper Award.
