A touchscreen interface is a display that allows users to interact with a device by touching the screen directly. This technology is commonly found in smartphones, tablets, and kiosks, enabling users to navigate menus, select options, and input data with their fingers. Touchscreens can be capacitive or resistive, with capacitive screens being more sensitive and responsive to light touches. These interfaces have revolutionized how we interact with technology, making it more intuitive and user-friendly. With the rise of smart devices and mobile applications, touchscreen interfaces have become a standard feature, enhancing accessibility and convenience in everyday tasks.
