<P>PROBLEM TO BE SOLVED: To discriminate multiple simultaneous contacts on a touch panel from a user. <P>SOLUTION: A multi-point touch-sensitive system includes: a touch-sensitive device; a microcontroller coupled to the touch sensitive device; and an electronic application coupled to the microcontroller. The touch-sensitive device has multiple electrically isolated conductive regions, so as to detect multiple simultaneous contacts a user has with the conductive regions. The touch-sensitive device generates output signals, one signal for each of the multiple simultaneous contacts, and transmits the output signals to the microcontroller. The microcontroller is configured to generate one or more control signals in response to the output signals and transmit the output signals to the electronic application. The electronic application includes a screen displaying multiple human-machine interactive objects. In response to the control signals, the electronic application alters the appearance of the human-machine interactive objects on the screen. <P>COPYRIGHT: (C)2010,JPO&INPIT |
