What makes touch screen work? Why do my fingers generally not do what they are supposed to do? I have use those 'rubber' pointers, but they quit before long. What is the problem? Help.

With my phone, i have sometimes had trouble accessing the touch screen with the hand I'm holding the phone with. I probably changed the capacitance effect that way.

Secondly - because you and I are "up in years", our fingers tend to be drier. I actually saw a disclaimer on my biometric gun safe that "persons above 65 years of age should not...." Basically it was warning that our fingerprints tend to be less recognizable.
See if a younger person has any trouble making your screen respond.The first to state his case seems right until another comes and cross-examines him.

They work by using capacitance. At least the modern ones to. Your skin is conductive and when you touch the screen, the capacitance at that location changes. Earlier touch screens worked by resistance and strain gauges. When you pressed on the screen, it deflected the glass and the strain gauge could use that to detect where you pressed.
