....functionality associated with the specific string, Play sounds, can be found in the application. The traversal produces a path through the Properties menu. Another possibility, not yet possible in our system, is suggested by research in automated evaluation of the visual layout of interfaces [14, 16]. In this case, layout evaluation would not be based on absolute metrics, but rather on relative comparisons for consistency. Our current work on the system falls into two areas. First, we are improving the robustness and generality of the implementation; we believe that it will eventually be ....

Layout appropriateness [22] is a metric aimed at assisting designers in organizing widgets in user interfaces based on the frequency of different sequences of actions users perform.

....parts that are already well placed. CONCLUSION AND FUTURE WORKS Experiments with Static and Dynamic Strategies What could be interesting is to automatically evaluate each result of the two strategies according to different metrics. The twocolumn strategy may receive a LA score (defined by Sears [10]) which is worse than the right bottom strategy. It is more likely that the right bottom strategy provides a layout which should be quasi LA optimal since it tries to follow the most frequent sequence among IO and to minimize blank space and gaps between groups. But this conclusion seems not to ....

Such strategies are the one column strategy applied in UIDE (de Baar, 1992) the one or two column strategy in GENIUS (Janssen, 1993) the balanced two column strategy in TRIDENT (Bodart, 1994b) the shape strategy in DON (Kim, 1993) the Layout Appropriateness (Sears, 1993), and the Right Bottom strategy in TRIDENT (Bodart, 1994b) Figure 3.

....in sub section 3.6 how dynamic task aspects such as the transitions between IOs may influence the arrangement of IOs. 3.6. Placement with Layout Appropriateness Sears developed a Layout Appropriateness (LA) method that can take advantage of a simple task description rather than a complete one (Sears, 1993). This metric is able to evaluate a layout, given different parameters detailing how users perform their tasks in the layout. These parameters integrate : the set of IOs, the sequences of performed actions, and their frequency. The LA metric is able to serve as basic measure for computer aided ....

....of visual aspects interfaces might be feasible. The tool would take as its input a definition of a screen layout and a task. The tool would provide as output a prediction of the time required for the user to execute the task. Previous researchers have set a precedent that such a tool can be built [10, 13]. Such a tool would analyze screen layouts and predict the cognitive effort required by a user to extract the information needed to accomplish a task.

.... routines are relevant for describing shifts in attention, for example; they could also be effective as components of a bottom up analysis of layout design, analyzing the possible paths a user s eye could trace out by following the explicit and implicit contours of boxes, text fields, and the like [Sears, 1993] . The eSimEye supports such behavior, but to a limited extent. For example, the system allows the controller to restrict the area to be searched for a specific object; this can be helpful if multiple instances are visible on the screen, but the only relevant item is, say, within the boundaries ....

....(Feiner, 1988; Kim Foley, 1993; Byrne et al. 1994) but there is very little experience with substantial commercial applications. Esthetically pleasing layouts are important, but the layouts should also match the sequence and frequency of the users s tasks. The term layout appropriateness (Sears, 1993, 1994) was chosen to convey the correspondence between layout and task. Layout appropriateness requires more inputs concerning usage patterns, but it is far more powerful in providing reliable evaluations and can even be used to generate layouts that would be optimal with respect to the metric of ....

....sparing, simplicity etc. Dynamic strategies for automated evaluation using these visual techniques have been introduced. Bodart, Hennebert, Leheureux and Vanderdonckt,1994) Visual metrics introduced above for traditional layout grids and multimedia layout frames have not yet been tested. Sears (1993, 1994) has developed a first generation tool using automated metrics for both design and evaluation using Layout Appropriateness metrics. The tool AIDE (semiAutomated Interface Design and Evaluator) allows designers to create, evaluate and modify an interface using a single tool. Layout ....

....designers to algorithmically generate initial layouts, interactively modify the layouts, and evaluate alternative layouts based on various metrics from within a single coordinated development environment. RELATED RESEARCH Automated metrics can be divided into two categories: task sensitive [12] and task independent [4, 13, 15] Task sensitive metrics take into account information about the users tasks. Task independent metrics are aesthetic sensitive metrics. These metrics do not incorporate any task information, but tend to be based on the principles of graphic design. Although good ....

....provides a quick overview of the status of any designer specified constraints. Efficiency compares the layout of the user interface widgets to the users tasks, ensuring that the users tasks guide the design of the interface. Efficiency is the Layout Appropriateness metric described by Sears [12] and helps predict task completion times and user preference rankings. At the present time, Layout Appropriateness (LA) is the only documented task sensitive metric that has been evaluated. The results of a sensitivity analysis on LA confirmed that this metric is not particularly sensitive to ....
