The History of Big Data Interfaces

$ hadoop fs -cat stuff

¡  Geometrical Zooming zooms the geometry of the view ¡  Semantic Zooming zooms the meaning of the view: §  Online maps: only show roads and rivers as the viewpoint gets closer §  Show the right level of detail for the zoom point §  Apply lenses to the data

¡  Spatial metaphors may require additional cognitive load…

¡  Hyperbolic Trees and lensing (Furnas 86, XeroX PARC): Focus + Context ¡  Pad and Pad++: Zoomable User Interfaces (1991) ¡  Cat-‐a-‐Cone, Themeriver ¡  Zoomable maps

Magnitudes Geospatial View HDFS HBase

HBase ZettaVox JSONVisualization Layer Services (HTML5, WebGL) (64 function API) caching Hadoop

¡  Level 1: HDFS file sizes ¡  Level 2: HDFS file content magnitudes ¡  Level 3: HDFS file content structure ¡  Level 4: HDFS file content fine structure ¡  Level 5: HDFS file content latent structure

¡  Dynamic calculation of requirements for ZettaZoom levels ¡  Caching of intermediary results with timestamps ¡  Recalculation for out-‐of-‐date data

¡  Big Data analysis requires new tools for visualization and data access ¡  Semantic Zooming supports multi-‐level interrogation of Big Data resources ¡  Lenses support dynamic wiring of visualizations to data values
