Touché technology enables a smartphone mute himself, for example, if the owner put a finger on his lips. This technology developed by Disney Research and Carnegie Mellon University is a form of capacitive touch sensing, the same principles that underlie the various types of touch screens that use a variety of smartphones.

The difference is, this technology not only monitors the electrical signal on one frequency, but also monitors the capacitive signals in a wide frequency range. Swept Frequency Capcitive Sensing (SFCS), trigger a reaction not only when there is a touch, but are able to recognize the complex configuration of the hand or body to the touch.
Reported by NDTV Gadgets, SFCS can improve the usability of everyday objects by using only one sensing electrode. In fact, as is the case door handles or other conductive object, the object itself can function as a sensor without the need to be modified. Human body or water can be a sensor.
According to Ivan Poupyrev, senior scientist at Disney Research, Pittsburgh, signal frequency sweeps have been used for decades in wireless communications, but there is no application in a touch interaction. "However, in experiments in our laboratory, we can improve. Sensitivity of the touch on various objects. When combined with gesture recognition techniques, Touché shows the recognition rate approaches 100 percent. It was demonstrated that this technology could be used to create new ways for humans to interact with various objects and the world at large, "said Poupyrev. *** [RIF | PIKIRAN RAKYAT 24052012]
