Accessibility
We aim to make PlanetHeartbeat useful with keyboard navigation, readable text and reduced-motion settings.
Keyboard use
Use Tab and Shift+Tab to move between links and controls, Enter or Space to activate controls, and Escape to close dialogs where implemented. The main page has keyboard-accessible skip links for the interactive globe and the main Earth content. The new status-panel link on the Data Sources page opens the matching source panel.
Motion and performance
The globe is a WebGL 3D experience that may require a modern browser and graphics acceleration. Motion-reduction and low-power settings are available in the interface where supported.
Non-3D alternatives
The Field Guide provides text-based Earth science explainers. Our data source directory links directly to source agencies.
Current limitations
A 3D globe, dense markers and animated imagery cannot yet provide a full equivalent to every visual interaction in assistive technologies. The project will continue improving descriptive alternatives and focus handling.
