Engineering Concern-Sensitive Navigation Structures: Concepts, Tools and Examples

Improving navigability in Web applications is a serious challenge for developers as this quality feature is essential for applications success. In this paper we present the concept of concern-sensitive navigation, a useful conceptual tool to improve navigation by profiting from the nature of application’s concerns. Concern sensitive navigation allows enriching Web pages with information, services or links related with the context in which pages are accessed.We show how our ideas are applied during the development process (e.g. by applying wise design strategies for separation of concerns) and can also be used by final users while adapting an application (e.g. by modding). Some examples of Web 2.0 sites are used to illustrate this last possibility. We also compare our research with other similar approaches such as the construction of adaptive Web applications.Facultad de InformáticaLaboratorio de Investigación y Formación en Informática Avanzada (LIFIA

A flexible architecture for client-side adaptation

Currently the Web allows users to perform complex tasks which involve different Web applications. Anyway they still have to face these tasks in a handcrafted way. Although it is possible to build service-based software, such as mashups, to combine data and information from different providers, many times this approach has limitations. In this paper we present an approach for Client-Side Adaptation aimed to support complex concern-sensitive and task-based adaptations with user-collected data. Our approach improves user experience by supporting user tasks among several Web applications.Publicado en Lecture Notes in Computer Science book series (LNCS, vol. 7059).Laboratorio de Investigación y Formación en Informática AvanzadaFacultad de Informátic

A Tool Support for Web Applications Adaptation Using Navigation History

Currently the Web is a platform for performing complex tasks which involve dealing with different Web applications. However users still have to face these tasks in a handcrafted way. In this paper we present a novel approach that combines concern-sensitive adaptation and navigation history to improve the user experience while performing a task. We have developed some simple though powerful tools for applying this approach to some typical tasks such as trip planning and house rental. We illustrate the paper with a simple though realistic case study and compare our work with others in the same field.Publicado en Lecture Notes in Computer Science book series (vol. 6949).Laboratorio de Investigación y Formación en Informática Avanzad

An approach for supporting distributed user interface orchestration over the Web

International audienceCurrently, a lot of the tasks engaged by users over the Web involve dealing with multiple Web sites. Moreover, whilst Web navigation was considered as a lonely activity in the past, a large proportion of users are nowadays engaged in collaborative activities over the Web. In this paper we argue that these two aspects of collaboration and tasks spanning over multiple Web sites call for a level of coordination that require Distributed User Interfaces (DUI). In this context, DUIs would play a major role by helping multiple users to coordinate their activities whilst working collaboratively to complete tasks at different Web sites. For that, we propose in this paper an approach to create distributed user interfaces featuring procedures that are aimed to orchestrate user tasks over multiple Web sites. Our approach supports flexible process modeling by allowing users to combine manual tasks and automated tasks from a repertoire of patterns of tasks performed over the Web. In our approach, whilst manual tasks can be regarded as simple instructions that tell users how to perform a task over a Web site, automated tasks correspond to tools built under the concept of Web augmentation (as it augments the repertoire of tasks users can perform over the Web) called Web augmenters. Both manual and automated tasks are usually supported by specific DOM elements available in different Web sites. Thus, by combining tasks and DOM elements distributed in diverse Web sites our approach supports the creation of procedures that allows seamless users interaction with diverse Web site. Moreover, such an approach is aimed at supporting the collaboration between users sharing procedures. The approach is duly illustrated by a case study describing a collaborative trip planning over the Web
