Touch interfaces are systems that allow users to interact with devices through physical touch. Commonly found in smartphones, tablets, and touchscreen computers, these interfaces use sensors to detect finger movements and gestures. This technology enables users to perform actions like tapping, swiping, and pinching to zoom, making it intuitive and user-friendly. The underlying technology of touch interfaces often includes capacitive or resistive screens. Capacitive screens, used in most modern devices, respond to the electrical properties of the human body, while resistive screens rely on pressure. Both types enhance user experience by providing direct manipulation of on-screen elements, such as buttons and icons.
