Imagine a blanket that knows where you're sitting. A touchscreen is kind of like that. When your finger touches the screen, it makes a tiny change in the electricity on the screen, and the screen reads that change to know exactly where your finger is. It's like the screen is listening for little whispers from your finger.
Examples
- Your finger leaves a tiny electrical whisper on the screen.
- The touchscreen listens and knows exactly where you tapped.
- It's like a magic map that follows your finger’s journey.
