<p><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 includes multiple electrically isolated conductive regions and the conductive regions are configured to detect multiple contacts from a user simultaneously and generate respective output signals for the multiple user contacts. The microcontroller is configured to receive the output signals from the conductive regions and generate one or more control signals in response to the output signals. The electronic application includes a screen displaying multiple human-machine interactive objects and a signal processor. The signal processor is configured to alter the appearance of the human-machine interactive objects on the screen in accordance with the control signals. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
