....its User Interface (UI) The User Interface is in itself a software system and as such possesses attributes or non functional requirements (NFRs) such as usability, reliability, simplicity, unambiguity, etc. 1] However, adaptability is emerging as an important characteristic for UI systems [1 ,2, 3, 4, 5, 6]. Adaptation of user interfaces has been a problem considered for a long time [24] Among the studies done in [24] are self adapting systems; another study uses adaptation for tailoring screens as per requirements [25] while yet another reason for adaptation is the development of intelligent user ....

....deal with many concurrent tasks in multiple windows with frequent switching between them [7] As a result, grouping windows in rooms seems only to have the benefit of a less cluttered screen space per room, but rapid access for task switching is still a problem. To address this, Elastic Windows [82], developed at the University of Maryland used their space filling tiled layout (for Treemap) technique for laying out windows. Overlapping is eliminated in this technique and all windows are accessible, except that some content will not be shown in windows with small size. However, all windows ....

....the display system is that it should maintain part whole relations between the compo nents and clearly show the user his position in the hierarchy. Traditional overlapping windows do not do this, they destroy part whole relationships. An attractive possibility is to use the notion of elasticity (Kandogan Shneiderman 1996) or fluidity (Zellweger, Chang, Mackinlay 1998; Chang, Mackinlay, Zellweger 2000) Both concepts are based on the idea that when something it opened it requires more space; however, this space is not acquired by obscuring objects but by deforming them as far as it is possible. The difference ....

....Lisp does not even support the lexical closures that Scheme provides SCWM. Neither GWM nor Sawmill has any constraint capabilities, though the hooks they provide can permit procedural implementations to approximate some of the simpler constraint based behaviours that SCWM affords. Elastic Windows (Kandogan Shneiderman 1996; 1997) is an interesting recent windowing system that uses spacefilling tiled layout. The Elastic Windows system does not provide general constraint capabilities, but instead does its layout by the implicit automatically maintained tiling and a dynamically alterable hierarchy of windows. ....

....information needed for a task to be placed and ordered in unnamed temporary structures. The visual arrangement of the information provides memory cues that organize and ease the task. Analyses of work flow indicate that people work with many tasks concurrently, with frequent switches between tasks [2]. Other studies show that users tend to use a rather small set of windows for a while, then delete or hide most of them, and then begin using another set of windows [1] This suggest that windowing systems must provide good mechanisms for window structuring, multi window operations, and ....

....to as window thrashing [1] Window housekeeping is an activity related to the computer domain and not to the user s task. Thus, the negative effects of window thrashing are not just the extra time spent on window housekeeping activities but also the loss of the user s mental task context [2]. These problems with independent overlapping windows, have resulted in a renewed interest in hierarchical tiled window layouts, e.g. the elastic window approach by Kandogan and Shneiderman [2] The elastic window approach tries to overcome the problems with independent overlapping windows at ....

Hierarchical organization of pages allows the user to see the context, while exploring further details lower in the hierarchy. Although syntactic information structure on the WWW is an arbitrary graph, presenting the information in a hierarchy can help users in their information seeking ....

....the nodes are made from this array, thus avoiding unnecessary traversals. Changes in the upper levels of the tree are propagated down the subtree to lower level nodes recursively, also avoiding unnecessary node traversals. More details on the window operations and layout dynamics are described in [14]. Scaling of page contents is done based on the window widths. Windows wider than a threshold value are reformatted keeping the same scaling factor. Galaxy libraries used in the implementation yielded sufficiently rapid graphics performance. RELATED WORK Research on web browsers provided many ....

....and increased information needs, modern users demand more functionality from window management systems. We proposed Elastic Windows with improved spatial layout and rapid multi window operations as an alternative to current window management strategies for efficient personal role management [12]. In this approach, multi window operations are achieved by issuing operations on window groups hierarchically organized in a space filling tiled layout. This paper describes the Elastic Windows interface briefly and then presents a study comparing user performance with Elastic Windows and ....
