Foreign Media Apple Insider reported that the United States Patent and Trademark Office has announced an Apple patent applications: the pressure-sensing gestures and touch input. In the patent application, described in the bottom of the screen is equipped with at least 3 equipment pressure sensor, pressure sensitive device integration through the borders of the screen, providing enhanced user interface navigation.

Patent shows touch on certain multitouch gestures is still insufficient, and new technologies will improve the situation. This type of system requires at least 3 pressure sensor (4 or more is better), they will be connected with the touch-sensitive area, but not necessarily visible to the user, such as being installed on the border of the iPhone or iPad.

In addition, the pressure sensor does not need to communicate and collaborate with each other and can work independently. Meanwhile, the distribution of part of the sensor can detect whether the user completed pressing operation when the touch. When the input pressure is sensed, each sensor will detect a different pressure values, analysis out of the center of pressure. After analysis, the system will determine the touch input or pressure to enter the content. Burberry iPhone 4 Case

In some applications, the pressure sensors are installed on touch input area. At this point, some user interface input screen, brought greater space for screen display. It is reported that the patent application also describes the center of pressure calculations, as well as future improvements of the control software.
