Logic for changing modes of operation of touch and proximity sensor that can change sensitivity

Provided are a system and method for changing a mode of operation of a touch and proximity sensor depending upon the strength of a signal from a detectable object relative to the touch and proximity sensor, wherein the system and method change sensitivity of the touch and proximity sensor by switching between discrete sensitivity modes of operation as the distance of the object in a three dimensional volume of space above the touch and proximity sensor changes, to thereby enable the touch and proximity sensor to accurately detect and the track a presence of one or more objects. 种根据与触摸和邻近传感器有关的来自可检测的目标的信号的强度来改变触摸和邻近传感器的操作模式的系统和方法，其中随着目标在触摸和邻近传感器上方的三维空间体积中的距离改变，系统和方法通过在离散灵敏度的操作模式之间进行切换来改变触摸和邻近传感器的灵敏度，从而使得触摸和邻近传感器能够准确性地检测和跟踪个或多个目标的存在。
