A touch interface is a technology that allows users to interact with devices by touching the screen. This interface is commonly found in smartphones, tablets, and touchscreen computers. Users can perform actions like tapping, swiping, and pinching to navigate through applications and access information. Touch interfaces rely on sensors that detect the presence and movement of fingers on the screen. This technology has made devices more intuitive and user-friendly, as it eliminates the need for physical buttons. Popular examples of touch interfaces include the Apple iPhone, Android devices, and Microsoft Surface tablets.
