A touchscreen interface is a display that allows users to interact directly with what is shown on the screen by touching it. This technology is commonly found in devices like smartphones, tablets, and kiosks. Touchscreens can recognize various gestures, such as tapping, swiping, and pinching, making them intuitive and user-friendly. There are two main types of touchscreen technologies: resistive and capacitive. Resistive touchscreens respond to pressure, while capacitive touchscreens detect the electrical properties of the human body. Both types enable users to navigate applications, input data, and control devices with ease, enhancing the overall user experience.
