Factors shaping the evolution of electronic documentation systems

The main goal is to prepare the space station technical and managerial structure for likely changes in the creation, capture, transfer, and utilization of knowledge. By anticipating advances, the design of Space Station Project (SSP) information systems can be tailored to facilitate a progression of increasingly sophisticated strategies as the space station evolves. Future generations of advanced information systems will use increases in power to deliver environmentally meaningful, contextually targeted, interconnected data (knowledge). The concept of a Knowledge Base Management System is emerging when the problem is focused on how information systems can perform such a conversion of raw data. Such a system would include traditional management functions for large space databases. Added artificial intelligence features might encompass co-existing knowledge representation schemes; effective control structures for deductive, plausible, and inductive reasoning; means for knowledge acquisition, refinement, and validation; explanation facilities; and dynamic human intervention. The major areas covered include: alternative knowledge representation approaches; advanced user interface capabilities; computer-supported cooperative work; the evolution of information system hardware; standardization, compatibility, and connectivity; and organizational impacts of information intensive environments

The role of user centred design in domestic energy demand reduction

The domestic sector currently accounts for approximately a third of the UK s energy use and so energy demand reduction in the domestic sector is a key part of the UK s strategy for carbon reduction. However, energy demand reduction has typically been addressed from an engineering perspective, with little consideration of the requirements of users. This PhD submission aims to identify how qualitative information about users experiences, values and practices relating to UK domestic energy demand reduction can be collected and presented effectively to an engineering audience and incorporated into engineering-focused energy research. User centred design is presented as a viable approach to understanding the context of energy use in UK homes and specifying requirements of the householders; as a way of ensuring user needs are included in this socio-technical problem space. This requires presentation of information about human behaviour in a form that is timely and appropriate to the engineering audience, who take a positivist view, preferring facts and figures to descriptions and anecdotes. A collection of nine publications, mostly peer-reviewed journal papers, by the thesis author and her co-authors is presented. Publications spanning from 2006 to 2014 illustrate a range of approaches to providing user centred information, from literature review to complex householder studies, which can provide information to enhance the engineering data and so provide additional insight and understanding. The research findings within the individual papers add to the body of knowledge on domestic energy use. In addition, the research identifies a number of roles where user centred design contributes to understanding of home energy use. From providing background and raising awareness of the presence of users within a system, to contextual understanding and the specification of user requirements, through to more sophisticated user characterisation, it is argued that user centred design can offer a significant contribution to the field. Future application of user information into engineering models, together with large scale, longitudinal studies of home energy use are proposed, building on the contributions of this thesis

Interactive Spaces Natural interfaces supporting gestures and manipulations in interactive spaces

This doctoral dissertation focuses on the development of interactive spaces through the use of natural interfaces based on gestures and manipulative actions. In the real world people use their senses to perceive the external environment and they use manipulations and gestures to explore the world around them, communicate and interact with other individuals. From this perspective the use of natural interfaces that exploit the human sensorial and explorative abilities helps filling the gap between physical and digital world. In the first part of this thesis we describe the work made for improving interfaces and devices for tangible, multi touch and free hand interactions. The idea is to design devices able to work also in uncontrolled environments, and in situations where control is mostly of the physical type where even the less experienced users can express their manipulative exploration and gesture communication abilities. We also analyze how it can be possible to mix these techniques to create an interactive space, specifically designed for teamwork where the natural interfaces are distributed in order to encourage collaboration. We then give some examples of how these interactive scenarios can host various types of applications facilitating, for instance, the exploration of 3D models, the enjoyment of multimedia contents and social interaction. Finally we discuss our results and put them in a wider context, focusing our attention particularly on how the proposed interfaces actually improve people’s lives and activities and the interactive spaces become a place of aggregation where we can pursue objectives that are both personal and shared with others

Situated Displays in Telecommunication

In face to face conversation, numerous cues of attention, eye contact, and gaze direction provide important channels of information. These channels create cues that include turn taking, establish a sense of engagement, and indicate the focus of conversation. However, some subtleties of gaze can be lost in common videoconferencing systems, because the single perspective view of the camera doesn't preserve the spatial characteristics of the face to face situation. In particular, in group conferencing, the `Mona Lisa effect' makes all observers feel that they are looked at when the remote participant looks at the camera. In this thesis, we present designs and evaluations of four novel situated teleconferencing systems, which aim to improve the teleconferencing experience. Firstly, we demonstrate the effectiveness of a spherical video telepresence system in that it allows a single observer at multiple viewpoints to accurately judge where the remote user is placing their gaze. Secondly, we demonstrate the gaze-preserving capability of a cylindrical video telepresence system, but for multiple observers at multiple viewpoints. Thirdly, we demonstrated the further improvement of a random hole autostereoscopic multiview telepresence system in conveying gaze by adding stereoscopic cues. Lastly, we investigate the influence of display type and viewing angle on how people place their trust during avatar-mediated interaction. The results show the spherical avatar telepresence system has the ability to be viewed qualitatively similarly from all angles and demonstrate how trust can be altered depending on how one views the avatar. Together these demonstrations motivate the further study of novel display configurations and suggest parameters for the design of future teleconferencing systems

Hypertext Semiotics in the Commercialized Internet

Die Hypertext Theorie verwendet die selbe Terminologie, welche seit Jahrzehnten in der semiotischen Forschung untersucht wird, wie z.B. Zeichen, Text, Kommunikation, Code, Metapher, Paradigma, Syntax, usw. Aufbauend auf jenen Ergebnissen, welche in der Anwendung semiotischer Prinzipien und Methoden auf die Informatik erfolgreich waren, wie etwa Computer Semiotics, Computational Semiotics und Semiotic Interface Engineering, legt diese Dissertation einen systematischen Ansatz für all jene Forscher dar, die bereit sind, Hypertext aus einer semiotischen Perspektive zu betrachten. Durch die Verknüpfung existierender Hypertext-Modelle mit den Resultaten aus der Semiotik auf allen Sinnesebenen der textuellen, auditiven, visuellen, taktilen und geruchlichen Wahrnehmung skizziert der Autor Prolegomena einer Hypertext-Semiotik-Theorie, anstatt ein völlig neues Hypertext-Modell zu präsentieren. Eine Einführung in die Geschichte der Hypertexte, von ihrer Vorgeschichte bis zum heutigen Entwicklungsstand und den gegenwärtigen Entwicklungen im kommerzialisierten World Wide Web bilden den Rahmen für diesen Ansatz, welcher als Fundierung des Brückenschlages zwischen Mediensemiotik und Computer-Semiotik angesehen werden darf. Während Computer-Semiotiker wissen, dass der Computer eine semiotische Maschine ist und Experten der künstlichen Intelligenz-Forschung die Rolle der Semiotik in der Entwicklung der nächsten Hypertext-Generation betonen, bedient sich diese Arbeit einer breiteren methodologischen Basis. Dementsprechend reichen die Teilgebiete von Hypertextanwendungen, -paradigmen, und -strukturen, über Navigation, Web Design und Web Augmentation zu einem interdisziplinären Spektrum detaillierter Analysen, z.B. des Zeigeinstrumentes der Web Browser, des Klammeraffen-Zeichens und der sogenannten Emoticons. Die Bezeichnung ''Icon'' wird als unpassender Name für jene Bildchen, welche von der graphischen Benutzeroberfläche her bekannt sind und in Hypertexten eingesetzt werden, zurückgewiesen und diese Bildchen durch eine neue Generation mächtiger Graphic Link Markers ersetzt. Diese Ergebnisse werden im Kontext der Kommerzialisierung des Internet betrachtet. Neben der Identifizierung der Hauptprobleme des eCommerce aus der Perspektive der Hypertext Semiotik, widmet sich der Autor den Informationsgütern und den derzeitigen Hindernissen für die New Economy, wie etwa der restriktiven Gesetzeslage in Sachen Copyright und Intellectual Property. Diese anachronistischen Beschränkungen basieren auf der problematischen Annahme, dass auch der Informationswert durch die Knappheit bestimmt wird. Eine semiotische Analyse der iMarketing Techniken, wie z.B. Banner Werbung, Keywords und Link Injektion, sowie Exkurse über den Browser Krieg und den Toywar runden die Dissertation ab
