A touchscreen is an intuitive display interface that responds to the touch of fingers or a stylus, eliminating the need for physical buttons or keyboards. It allows users to interact directly with on-screen content, making navigation faster and more engaging. Common in smartphones, tablets, and modern monitors, touchscreens use capacitive or resistive technology to detect input. Capacitive screens support multi-touch gestures like pinching and swiping, while resistive screens rely on pressure. They are widely used in retail kiosks, ATMs, and industrial controls due to their ease of use. Touchscreens enhance accessibility and streamline workflows, making them essential in today's digital world. Their responsiveness and versatility have revolutionized how people communicate, work, and access information.
