Mutual Capacitance 

Mutual capacitance is the intentional or unintentional capacitance between two "charge holding objects." Projected capacitance touchscreens intentionally create mutual capacitance between elements of columns and rows [see figure 6] in the vicinity where each intersect the other. This allows the system electronics to measure each node (intersection) individually to detect multiple touches on the screen during one screen scan. When a finger touches near an intersection, some of the mutual capacitance between the row and column is coupled to the finger which reduces the capacitance at the intersection as measured by the system electronics. This reduced capacitance crosses the "touch threshold" set by the electronics indicating a touch has occurred.
