Imagine your smartwatch is like a tiny detective inside your wrist. It has special sensors called accelerometers that can feel the slightest shake, like when you walk or run. Every time you move, even just a little, it notices and counts it as a step. That’s how it knows you're moving without touching anything.
Examples
- Your smartwatch feels the shake in your wrist when you walk.
- It senses a little jolt every time you take a step.
- Even sitting down slightly moves it enough to count as activity.
