....While Side Views can open up the interface, making its functionality less opaque to users, informal testing has shown that Side Views does not cleanly scale when users wish to work with many commands, or commands with many parameters. One possible solution to this problem is zoomable interfaces [1, 2], which may offer tools to better Figure 4. Parameter spectrums display a spectrum of previews covering a range of values for each parameter. Figure 3. Side Views can persist, offering dynamic previews. In the figure above, the user changes the active document from the star to the square, ....

....multiple scales is a popular method of virtually expanding the space. In the 2D realm, Masui provided a means to navigate through an information space by modifying the search area in each view [19] Bederson in Pad built a graphical interface in which zooming is the principle means of navigation [2]. In these systems, users had to manually keep track of the different viewpoints from which they were working. Igarashi integrated rate based scrolling with automatic zooming, giving the user a global view of documents as the scroll rate increases [15] We extend Igarashi s work and present ....

....zooming) The correctness and robustness requirements that we will guarantee concern the composition of DASADA components in the presence of changes in the scale of interaction. While there are many approaches to dealing with the variance of resolution of presentation output (e.g. PAD [6, 5]) our approach handles scale for both output and input, which facilitates the design and assembly of multi scale, interactive components. To develop these applications, we must overcome the inherent difficulty of managing dynamic composition at many different levels of granularity ....

....rectangle can be used to approximate some of the computational benefits of a true hierarchy. Unbounded workspace representation. The space manager is currently initialized by the user to work within a bounded rectangular workspace. Alternatively, to support infinitely zoomable user interfaces [2], it can be used as an unbounded manager, whose workspace ranges from # to # in each dimension (e.g. represented as the largest negative and positive floating point values) When computing window dimensions during a query, the user could optionally clip these to her own, possibly changing, ....

....transformation. Figure 6 shows an example of our interactive atlas using both LOD and object size based on implicit magnification. This is but one simple example of how LOD rendering can be incorporated into nonlinearly magnified spaces, many other approaches are possible; for example the Pad [2] WWW navigation system uses page thumbnails with a LOD function so that the node at the focus of the transformation becomes an actual web page which the user can interact with, other systems for visualization of graph structures expand and collapse subgraphs as their root nodes are magnified or ....

Because of its advantages, information visualization has been used as an aid in problem solving tasks in a variety of applications, such as software engineering [19] social network analysis, and Web navigation [19] Detecting ....

....to the user, the new visualizations should be created in less than 100 milliseconds [27] Thus, it is important that the mapping be one that can be computed quickly. Our experiments suggest that the simple linear mapping used by our prototype system ts this criteria. 2.2. 2 Zooming Zooming [1] allows the user to magnify a portion of the visualization, and view it in greater detail. It may help the user in detecting clusters that may be hidden under other clusters in the visualization. In Section 3, we describe a similar scenario, where zooming helped in discovering a cluster hidden ....

....maps [30] to cone trees [51] to hyperbolic browsers [44] However, these techniques handle data that is itself a hierarchy, such as filesystems; our work is focused on visualizing data sets that are organized using hierarchical meta data, such as the schema shown in Figure 6.4. The Pad project [6] has explored interfaces for navigating large data spaces using semantic zooming and task based filtering. While Pad has explored multiscale displays, they do not address data management schemes for hierarchical multi dimensional data. The Sage group at CMU has worked with hierarchical data, ....

....snowflake schemas. We solve this problem in TierBar with pulldowns, but other solutions should also be explored. A further extension would be not only to change the level of detail being displayed when zooming, but also to change the visual representation of the data as well, as in Pad [6]. For example, when the level of detail of time gets fine enough, the graph would change from a utilization strip chart to a Gantt chart of individual events. We also plan to extend the underlying data infrastructure. First, we would like to support ad hoc grouping and aggregation, such as ....

....for transforming points and graphic primitives like images. These transformations are applied by wrapper objects which are inserted into the view hierarchy and which wrap the view to be transformed without needing to change it. A similar idea is followed by introducing the portals in Pad [5] or the internal cameras in Jazz [6] 4 Example Device Configurations To illustrate how this architecture can be used for different devices and configurations this section gives three examples. The examples are taken from the experience with the implementation of BEACH, which was developed based ....

....a toolkit based solution. On the other hand, a more complex component such as an interactive graph probably does. Let us start by defining our requirements for such a toolkit. In our research, we are particularly interested in new visualization techniques, such as Zoomable User Interfaces (ZUIs) [10, 11, 12, 13] and fisheye visualizations [9, 16] We are also interested in animation and in dynamic data displays. For components that support our needs, a range of toolkit requirements arise: 1) The toolkit must be small and easy to learn and use with an existing GUI framework. 2) The toolkit must manage ....

....zooming and panning is weak. It also provides no support for multiple cameras, making it problematic for creating our zooming interfaces. There were several prior implementations of Zoomable User Interfaces toolkits as well. These include the original Pad system [22] and more recently Pad [11, 12, 14], as well as other systems [15, 23, 24] and a few commercial ZUIs that are not widely accessible [1, 25; Chapter 6, 30] All of these previous ZUI systems are implemented in terms of a hierarchy of objects. However, like GUI toolkits, they use a monolithic class structure that places a large ....

As such, it builds primarily on the results and experiences gained from both the Jazz [3] and Pad [2] systems. Our system is perhaps most similar in spirit to VIKI, a spatial hypertext tool for supporting emergent structure during authoring [13] One particularly relevant application of VIKI was its use in gathering and organizing content for educational presentation on the web [18] Here ....
