Engineering context-aware systems and applications:A survey

Context-awareness is an essential component of systems developed in areas like Intelligent Environments, Pervasive & Ubiquitous Computing and Ambient Intelligence. In these emerging fields, there is a need for computerized systems to have a higher understanding of the situations in which to provide services or functionalities, to adapt accordingly. The literature shows that researchers modify existing engineering methods in order to better fit the needs of context-aware computing. These efforts are typically disconnected from each other and generally focus on solving specific development issues. We encourage the creation of a more holistic and unified engineering process that is tailored for the demands of these systems. For this purpose, we study the state-of-the-art in the development of context-aware systems, focusing on: (A) Methodologies for developing context-aware systems, analyzing the reasons behind their lack of adoption and features that the community wish they can use; (B) Context-aware system engineering challenges and techniques applied during the most common development stages; (C) Context-aware systems conceptualization

Coordination Of Hierarchical Command And Control Services

The purpose of this program is to show emerging information technologies can significantly improve key areas of tactical operations, resulting in the conversion of software developed under the ATO to existing battlefield systems. One such key area is Information Dissemination and Management (ID&M). The key software that will be developed under the ID&M portion requires a collection of agent-based software services that will collaborate during tactical mission planning and execution

The SEMAINE API : a component integration framework for a naturally interacting and emotionally competent embodied conversational agent

The present thesis addresses the topic area of Embodied Conversational Agents (ECAs) with capabilities for natural interaction with a human user and emotional competence with respect to the perception and generation of emotional expressivity. The focus is on the technological underpinnings that facilitate the implementation of a real-time system with these capabilities, built from re-usable components. The thesis comprises three main contributions. First, it describes a new component integration framework, the SEMAINE API, which makes it easy to build emotion-oriented systems from components which interact with one another using standard and pre-standard XML representations. Second, it presents a prepare-and-trigger system architecture which substantially speeds up the time to animation for system utterances that can be pre-planned. Third, it reports on the W3C Emotion Markup Language, an upcoming web standard for representing emotions in technological systems. We assess critical aspects of system performance, showing that the framework provides a good basis for implementing real-time interactive ECA systems, and illustrate by means of three examples that the SEMAINE API makes it is easy to build new emotion-oriented systems from new and existing components.Die vorliegende Dissertation behandelt das Thema der virtuellen Agenten mit Fähigkeiten zur natürlichen Benutzer-Interaktion sowie emotionaler Kompetenz bzgl. der Wahrnehmung und Generierung emotionalen Ausdrucks. Der Schwerpunkt der Arbeit liegt auf den technologischen Grundlagen für die Implementierung eines echtzeitfähigen Systems mit diesen Fähigkeiten, das aus wiederverwendbaren Komponenten erstellt werden kann. Die Arbeit umfasst drei Kernaspekte. Zum Einen beschreibt sie ein neues Framework zur Komponenten-Integration, die SEMAINE API: Diese erleichtert die Erstellung von Emotions-orientierten Systemen aus Komponenten, die untereinander mittels Standard- oder Prä-Standard-Repräsentationen kommunizieren. Zweitens wird eine Systemarchitektur vorgestellt, welche Vorbereitung und Auslösung von Systemverhalten entkoppelt und so zu einer substanziellen Beschleunigung der Generierungszeit führt, wenn Systemäußerungen im Voraus geplant werden können. Drittens beschreibt die Arbeit die W3C Emotion Markup Language, einen werdenden Web-Standard zur Repräsentation von Emotionen in technologischen Systemen. Es werden kritische Aspekte der Systemperformanz untersucht, wodurch gezeigt wird, dass das Framework eine gute Basis für die Implementierung echtzeitfähiger interaktiver Agentensysteme darstellt. Anhand von drei Beispielen wird illustriert, dass mit der SEMAINE API leicht neue Emotions-orientierte Systeme aus neuen und existierenden Komponenten erstellt werden können
