Main Goal of the Work What is the goal? The creation of a Development Method for User Interfaces of Rich Internet Applications The introduction of a meta-model of user interfaces for Rich Internet Applications establishes a common ground to standardize their design and development through a modelbased and neutral representation which could be ported by a transformational schema to various web development environments. 3 Belgian Laboratory of Computer-Human Interaction (BCHI) : : : UCL August 2007
Focus What is the focus of this thesis? Web Applications Which Type of User Interfaces is studied? Graphical User Interfaces To whom is directed this work? The CHI research community, academics interested in webapps 4 Belgian Laboratory of Computer-Human Interaction (BCHI) : : : UCL August 2007
Introduction| The Web Platform The World Wide Web (or simply web) is based upon three core components: The Uniform Resource identifier, the interaction protocols used by the agents to get the resources and a representation of the data contained by the resource 5 Belgian Laboratory of Computer-Human Interaction (BCHI) : : : UCL August 2007
Introduction| The Web Architecture The original function of the web was to deliver plain hypertext documents over a client-server architecture but its success has caused a natural evolution from static and passive contents to dynamic and interactive ones. 6 Belgian Laboratory of Computer-Human Interaction (BCHI) : : : UCL August 2007
Introduction| Web App. Architecture The web browser remains as the immovable and universal client. The application server is the most important element in the second-tier (the server one) because it supplies the environment to execute the components of the application. Finally, in the third-tier is included a repository of data that is available through a data access interface from the second-tier 7 Belgian Laboratory of Computer-Human Interaction (BCHI) : : : UCL August 2007
Introduction| Rich Internet Application The RIAs are webapps that take into account the power of the client to increase the responsiveness of the Web UI while the management of the application and data remains on the server. 8 Belgian Laboratory of Computer-Human Interaction (BCHI) : : : UCL August 2007

The Role of XLST The reification process is the process to iterating from the abstract representation to more concrete levels and ultimately arrives to the Final User Interface. This overall procedure is called: forward engineering. The CAMALEON framework requires from each UI representation a process of transformation to deliver the next step. 15 Belgian Laboratory of Computer-Human Interaction (BCHI) : : : UCL August 2007

Step 2 | Design of the Menu Definition The concept of menu is the activation of a group of actions. A menu is constituted by a name and a list of actions called menu items. Usually, a menu item is followed by an accelerator, i. e. a combination of keywords that allows selecting an item without mouse or keyboard selection. The advantage of menus is allowing the utilization of the options of the application without worrying about memorizing commands [Vand 98] 41 Belgian Laboratory of Computer-Human Interaction (BCHI) : : : UCL August 2007

Conclusion The purpose of this work was to establish the master plan of our method to develop RUIs. All the steps have been presented in the current document. These steps are the beginning of a variation/expansion of the Usi. XML family of tools and models in order to target RIAs is an ongoing work. 56 Belgian Laboratory of Computer-Human Interaction (BCHI) : : : UCL August 2007

Summary of contributions • The contributions are expanded in a series of exploratory papers in which we began to understand more the model of the RIAs: – [Mart 06], where present the first attempt to tackle the problem – [Muño 06] where we propose a taxonomy of RIAs – [Mart 06 a] a study case based on XAML UIs. • We have integrated here a proposal of extensions to the task types and menu features relevant to RIAs (see chapter 3 and 4). • A proposal of a method for the generation of the container structure • And Finally, The generation of menus based on task trees 58 Belgian Laboratory of Computer-Human Interaction (BCHI) : : : UCL August 2007
Future work • The process of making grow our repository of the UI widgets used in RIAs (for complete the XSLT templates). • The integration of the RIA frameworks GWT into the Grafi. XML tool as target language (extension to Usi. XML). • The integration of some elements to make simpler the translation between models, specifically the collecting of patterns to reduce the process of conversion (simplify the XLST translation). • The web is a distributed environment, we have to profit of that and integrate to the solution the power of the cooperative systems i. e. , web agents. • A proposal of a RIA Behaviour model 59 Belgian Laboratory of Computer-Human Interaction (BCHI) : : : UCL August 2007
