A capacitive touch screen allows the user to control display elements by detecting the electrical properties of the human body. It does so by sensing the conducive properties of an object, such as the skin of a fingertip.
A capacitive touch screen on a smartphone typically has a glass face that does not rely on pressure to detect the touch of a finger. Unlike a resistive screen, a capacitive touch screen is more responsive and allows for more precise command input. However, it is not able to detect input if a user is wearing gloves or using a stylus. As of 2014, the Samsung Galaxy S and the Apple iPhone are examples of devices with capacitive touch screens.
