Drawing upon existing literature on Drawing upon existing literature on zooming interface technology, intuitive zooming interface technology, intuitive navigation of large volumes of data, navigation of large volumes of data, query previews, and hierarchical query query previews, and hierarchical query results, we propose a visual data results, we propose a visual data search tool with implicit spatial search tool with implicit spatial boolean logic and a 3D (two boolean logic and a 3D (two dimensions of space and one of scale) dimensions of space and one of scale) query preview window that will allow query preview window that will allow fast, dynamic searchesfast, dynamic searches..

Existing Existing Zooming Zooming TechnologiesTechnologies

Pad/Pad++Pad/Pad++ Pad is a continuously zoomable

interface that navigates through a set of data that can be described in two dimensions. The data is grouped in a hierarchy that is built over this data. Information may be stored in the nodes or leaves of the resulting tree.

Navigation through the tree includes interstitial animations (zooming) that provide hints as to user’s current position within the hierarchy.

Space/Scale DiagramsSpace/Scale Diagrams Space-Scale Diagrams:

Understanding Multiscale Interfaces George W. Furnas and

Benjamin B. Bederson Provide a means of describing

different zooming techniques.

Pad/Pad++Pad/Pad++ 2D data image mapped over 3rd

dimension (scale) Pad is a 2D + 1D mapping space, where

the 1D is scale Panning and zooming operations can

be visualized in this space for a constant size window navigating in

3 dimensions panning moves are within a constant x-y

plane zooming moves are up and down the z

axis

Fisheye ViewFisheye View Generalized Fisheye Views (1986)

George W. Furnas Combine some features of full-zoom

technology with some contextual information.

Describe a “degree of interest”--information that is of greater interest to the user will be zoomed, but contextual information will remain.

Structures and Relations in Complex Graphics Andreas Raab and Michael Ruger

Application of fisheye zoom techniques for visualizing 3D medical models. 3D + 1D data space.

Allows for deformation of contextual information and transparency to de-emphasize contextual information.

Fisheye ViewFisheye View

Fisheye views can be described by space-scale diagrams fisheye views can be seen as

overlapping windows in the 2D + 1D space

with deformations, fisheye views more closely resemble a lens in 3D space
