Screens, computers, smartwatches, and smartphones all have touchscreens that allow for an interactive user experience. What technologies are involved in the functionality of these touchScreens, and how do they enable user interaction through the screen? Please answer in 4 sentences and use the term "capacitive" at least once.

Touchscreens in devices like computers, smartwatches, and smartphones primarily use capacitive technology, which involves a layer that stores electrical charge. When a finger, which is electrically conductive, touches the screen, it draws a tiny amount of charge, causing a disruption in the touchscreen's electrostatic field. This disruption is detected by sensors at the point of contact, which then sends the information to the processor to interpret the touch as a specific command or input. Thus, capacitive touchscreens enable a highly responsive and intuitive user interaction experience, supporting gestures like tapping, swiping, and pinching.
