The accelerometer is a core mobile sensor that detects device movement and orientation in three-dimensional space. Its capabilities enable:

Movement tracking:

• Detects device tilts and rotations
• Measures motion intensity and direction
• Recognizes specific gesture patterns

Common applications:

• Automatic screen rotation based on device position
• Motion controls in mobile games
• Step counting and activity tracking in fitness apps
• Navigation adjustments in map applications
• Gesture-based commands like "shake to undo"

The accelerometer works alongside other sensors (gyroscope, compass) to provide precise motion data, enabling more natural and intuitive interactions with mobile devices.
