Getting Users Involved in Aligning Their Needs with Business Processes Models and Systems

Abstract: This paper aims to present a case study of the application of a methodology that represents an innovative strategy that integrates researches on interaction design and business process management with practical implications. This methodology is devoted to aligning the needs of enterprise system users with business processes (BPs). This approach establishes an unbroken network of links between BPs, task models and abstract representations of user interfaces. Once the models are linked, it is possible to identify the impact that any change on these models may produce in other models. The main challenge is to organize the linked models according to the organizational context and manage those links with consistency in order to support improving process efficiency and user productivity. This approach has been applied in a large telecommunications organization during four months with its application in two different projects and validated with a cost-benefit analysis. Applying this approach in large organizations has demonstrated that: every involved stakeholder is capable of understanding the whole approach in one working day; creating the models and linking them with the corresponding business process models takes around three men/day per core business process; and applying this approach brings up to 60 per cent of return on investment related to process improvement and user experience. The main differentials of this methodology include using simple models; considering light actions; preserving the independence of technology; and adopting a human-oriented approach assuring that every managed information impacts people and not only systems, thus enabling fast adaptation to the business dynamism.

A Resource Oriented Multimedia Description Framework

Abstract: This chapter presents a multimedia archiving framework to describe the content of multimedia resources. This kind of content is very rich in terms of meanings and archiving systems have to be improved to consider such richness. This framework simplifies the multimedia management in existing applications, making it accessible for non-specialized developers. This framework is fully implemented on the REST architectural style, precisely mapping the notion of resource with media artifacts, and scaling to address the growing demand for media. It offers an extensive support for segmentation and annotation to attach semantics to content, helping search mechanisms to precisely index those content. A detailed example of the framework adoption by a medical imaging application for breast cancer diagnosis is presented.

Multi-domain Framework for Multimedia Archiving Using Multimodal Interaction

Abstract: Multimedia content is very rich in terms of meaning, and archiving systems need to be improved to consider such richness. This research proposes archiving improvements to extend the ways of describing content, and enhance user interaction with multimedia archiving systems beyond the traditional text typing and mouse pointing. These improvements consider a set of techniques to segment different kinds of media, a set of indexes to annotate the supported segmentation techniques and an extensible multimodal interaction to make multimedia archiving tasks more user friendly.

Service-Oriented Architecture for Supporting Collaborative User Interface Development

Abstract: Professionals working in organizations that conduct any user interface development life cycle are more and more involved in a collaborative setup where competences and resources are distributed in time and space. In order to support this shift of practice, a service-oriented architecture is defined and developed according to principles of model management. In this paradigm, user interaction development is decomposed into activities, which could be supported by model management operations. These operations are in turn converted into services, developed according to the service-oriented architecture. A distributed user interaction development life cycle consequently involves the following steps: a method engineer defines the activities to be conducted for the user interface of a project, the method definition is imported in the software architecture to enact the method by assigning responsibilities to team members, and these members then perform their responsibilities through the services corresponding to the operations. This paper also presents a taxonomy of services for supporting the user interface development life cycle that is unique.

Interface of Multimodal Searching on Multimedia Archives
