Understanding the Device Orientation API

What is the Device Orientation API?

The Device Orientation API provides access to the device's physical orientation and motion data. It allows web applications to respond to changes in device orientation and movement.

Key Features

  • Access device orientation angles (alpha, beta, gamma)
  • Support for absolute and relative orientation
  • Permission-based access control
  • Real-time orientation updates
  • Cross-browser compatibility

Browser Support

The Device Orientation API is supported in most modern browsers on mobile devices. Some browsers may require HTTPS and explicit user permission.

Best Practices

  • Always check for API support
  • Request permissions when needed
  • Handle null values gracefully
  • Clean up event listeners
  • Consider device compatibility

Example Use Cases

  • Virtual reality experiences
  • Interactive games
  • Augmented reality applications
  • Device motion tracking
  • Orientation-based UI adjustments
