3. The Mexican International Conference on Computer Science ENC 2008 3 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.

4. The Mexican International Conference on Computer Science ENC 2008 4 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.

16. The Mexican International Conference on Computer Science ENC 2008 16 Classification of Containers Adjacent Disposition This feature is the relation of adjacency between tasks. two categories are possible:Contiguous and Non- contiguous. Capacity That 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).

17. The Mexican International Conference on Computer Science ENC 2008 17 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.

22. The Mexican International Conference on Computer Science ENC 2008 22 Conclusions In 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.
