What is an example of a capacitive touch screen?
An example of a capacitive touch screen is the one commonly found on smartphones and tablets. These touch screens use the electrical properties of the human body to detect touch, allowing for multi-touch gestures like tapping, swiping, and pinching. When you touch the screen with your finger, it disrupts the electrical field of the screen, allowing the device to detect the location and movement of your touch.
