Understanding Motion Sensors
What Are Motion Sensors?
Modern smartphones and tablets contain multiple motion sensors that detect device movement and orientation. These sensors enable features like automatic screen rotation, fitness tracking, and augmented reality applications.
This tool provides direct access to your device's motion sensors through web browser APIs, allowing you to verify sensor functionality and observe real-time sensor data.
Types of Motion Sensors
Accelerometer
Measures acceleration forces acting on the device, including gravity. The accelerometer detects motion along three axes: X (left-right), Y (forward-backward), and Z (up-down). When stationary, the accelerometer reads approximately 9.8 m/s² in the direction of gravity.
Gyroscope
Measures the rate of rotation around the device's three axes. Unlike the accelerometer, the gyroscope is unaffected by gravity and provides angular velocity data. This sensor is essential for tracking device orientation changes and rotational movements.
Orientation Sensors
Combines data from the accelerometer, gyroscope, and optionally the magnetometer to determine the device's absolute orientation in 3D space. Orientation is expressed using three angles: Alpha (compass heading), Beta (front-back tilt), and Gamma (left-right tilt).
Common Applications
Gaming
Racing games, flight simulators, and AR games use motion sensors for intuitive tilt-based controls.
Fitness Tracking
Step counting, workout detection, and activity monitoring rely heavily on accelerometer data.
Navigation
Augmented reality navigation and compass applications use orientation sensors to overlay directions on camera views.
Photography
Camera apps use motion sensors for optical image stabilization and panorama capture alignment.
Technical Notes
- Motion sensors require HTTPS for security reasons. Sensor data is processed entirely in your browser.
- iOS 13 and later require explicit user permission before accessing motion sensors. Tap the Start button to trigger the permission dialog.
- Sensor accuracy varies between devices. Consumer-grade sensors are suitable for general motion detection but not for precision measurements.
Browser Compatibility
Motion sensor support varies across browsers and platforms:
For best results, use this tool on a mobile device with the latest browser version.
