Touchscreen devices are electronic gadgets that allow users to interact with the screen directly by touching it. This technology is commonly found in smartphones, tablets, and laptops. Touchscreens can detect multiple points of contact, enabling gestures like tapping, swiping, and pinching to zoom. These devices use either resistive or capacitive technology. Resistive touchscreens respond to pressure, while capacitive touchscreens detect the electrical properties of the human body. Touchscreen devices have become popular due to their intuitive interfaces, making it easier for people to navigate applications and access information quickly.
