context-aware generation of user interface containers for a mobile device
DESCRIPTION
The world of the mobile devices involves restrictive features. Multiple efforts have been done to define the User Interface. Here, it is combined a neutral description of the UI with a semantic recovery of information. The focus of this paper is the generation of the containment structure based on the context of the application. The process includes three main tasks: first a fixed division of the neutral definition of the UI (a task tree), Then heuristic rules based on the vicinity are applied and finally a set of container patterns is provided to polish the UI. Alternative configurations are delivered and weighted. Since multiple metrics has been proposed a comparison of them was delivered. The results of the comparative analysis suggest that some metrics, although more sophisticated and fine-grained, do not necessarily improve significantly the quality of determining user interface containers, therefore stemming for simple, yet efficient, metrics used to reach a threshold. Finally, as final result is a set of plausible UIs is delivered.TRANSCRIPT

Introduction
The design of User Interfaces involves a process of gathering building blocks. These hierarchies of elements are the representation of the goal pursuit by the application.

Introduction
The specific features of a context lead designers to take particular design decisions.
For instance, the Mobile World introduces interesting challenges in terms of limited space and computational capacities.

Classification of Containers
Adjacent Disposition This feature is the relation of adjacency between tasks. two categories are possible:Contiguous and Non-contiguous.
CapacityThat is the amount of embedded tasks/elements inside a container. (Also it is possible to understand it as the number of children nodes under a parent node i.e. the cardinality).

Classification of Containers
HR1: Sequential operators could be associated with contiguous configurations since they are obliged to follow N
HR2: the discontinuous configuration should be associated to choice or concurrent operators.

ConclusionsIn this paper, it has been described an iterative method to help UI designers in the process of defining containment structures in the mobile domain.
This method takes into account contextual information (the platform, temporal relationships between tasks and vicinity of the tasks) and the posibility of applying a pattern library (for the containers) to refine the UI.
Finally, A fundamental consideration is the fact that our method for the moment is not looking optimization instead of that, it provides plausible scenarios to the designer.
