Multi-touch Systems
To allow people to use touch commands that require multiple fingers, the new arrangement of existing technology. Its touch-sensitive screen includes a layer of capacitive material, just like many other touch screens. However, the capacitors are arranged according to a coordinate system. Its circuitry can sense changes at each point along the grid. In other words, every point on the grid generates its own signal when touched and relays that signal to the processor. This allows the location and movement of simultaneous touches in multiple locations. Because of its reliance on this capacitive material, the works only if you touch it with your fingertip -- it won't work if you use a stylus or wear non-conductive gloves.
the screen detects touch through one of two methods: Mutual capacitance or self capacitance. In mutual capacitance, the capacitive circuitry requires two distinct layers of material. One houses driving lines, which carry current, and the other houses sensing lines, which detect the current at nodes.
Self capacitance uses one layer of individual electrodes connected with capacitance-sensing circuitry.
Both of these possible setups send touch data as electrical impulses. In the next section, we'll take a look at exactly what happens.
