Imagine your touchscreen is like a big chocolate bar. When you tap it, it’s like you’re pressing on one of the squares, and the bar knows exactly where you pressed. Touchscreens use something called capacitive touch, which means they sense changes in electricity when your finger touches them. It’s like your finger adds a little bit of magic to the screen so it can tell where you tapped.
Examples
- When you tap your phone, it feels like it’s reading your mind, but really, it’s just sensing electricity from your finger.
- Your tablet knows where to draw when you write on its screen because it feels the change in electric signals under your finger.
- You can pinch to zoom on a map app because your fingers both send electrical changes to the screen at once.
