I'm reading about the electronics in touch screen. It says when i touch the panel it distorts the electrostatic field and thus will have a change in capacitance. This is how it detects My question is the electrostatic field same as electric field? Please explain in details How did the capacitance change when i just touch the panel

Compensation Techniques

The compensation techniques are the methods that are employed in the electrical control systems to enhance the performance of the system. The performance are generally affected by the factors like lag in the compensating devices, slow response of the system of the components like sensors used in the control system. The basic compensation technique involves lag compensation, lead compensation or the combination of the both.
