Smartphones have little helpers inside them called sensors that can feel how you move. One is like a tiny gyroscope, which helps the phone know when it's spinning, and another is an accelerometer, which tells it when you're speeding up or slowing down. Together, they work like a team to tell if you're walking, running, or even just sitting still. It’s like having a mini detective inside your phone that follows you everywhere.
Examples
- Your phone knows you're walking if it feels your steps like a tiny detective.
- If you turn the phone while walking, the gyroscope notices the spin.
- The accelerometer detects that you’re moving forward at a steady pace.
