First Claim
1. A computer-implemented method, comprising:
- at a touch-sensitive device having multiple electrically isolated conductive regions,detecting multiple simultaneous contacts a user has with the conductive regions;
generating multiple output signals, one signal for each of the multiple simultaneous contacts;
transmitting the output signals to a microcontroller, wherein the microcontroller is configured to generate one or more control signals in response to the output signals;
transmitting the control signals to an electronic application, wherein the electronic application includes a screen displaying multiple human-machine interactive objects; and
altering the appearance of the human-machine interactive objects on the screen in response to the control signals.

Abstract
A computer-implemented method in connection with a multi-touch detection system is disclosed. The multi-touch detection 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. In response to detecting multiple simultaneous contacts a user has with the conductive regions, the touch-sensitive device generates multiple 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 control 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.
