Developing UCAF, an administrative functionality for the U-Call IVR reporting system
No full textMobile phones and Interactive Voice Response (IVR) applications are being progressively used in developing countries to collect voice-based reports about bad governance or poor public service delivery, reported by citizens. Such systems (e.g. Avaaj Otalo, Foroba Blon, etc.) can give an opportunity to rural users in developing countries to easily influence and participate in public affairs. Despite the ongoing efforts on using such solutions, the lack of an efficient system of administration can cause delays in broadcasting the collected reports as quickly as possible, to reach the relevant authorities. This thesis presents the results of a real-world deployment of an administrative functionality for an IVR system called U-Call, used in the Northern districts of Uganda. U-Call Administrative Functionality (UCAF) interacts with the U-Call administrators through mobile phones and gives the moderator access to the registered users. It allows administrators to easily publish and tag audio reports over the Web using their mobile phones. It also uses a semantic tagging module to increase findability and information categorization on the U-Call’s website. After an initial validation and successful evaluation of UCAF in the field, during a trip to Uganda, additional features were incorporated, such as multiple authentication process and dynamic tagging. UCAF and its additional features was succefully delivered to the end user, as part of the U-Call reporting system.People’s Voices: Developing Cross Media Services to Promote Citizens Participation in Local Governance Activitie

Interweaving Technology : Understanding the Design and Experience of Interactive Performances
No full textThis thesis builds on the growing interest in studying interactive performances within the fields of Human-Computer Interaction (HCI) and Interaction Design (IxD). The overarching goal of this research is to investigate how creative teams and artists can incorporate interactive technologies into their artistic productions. This thesis draws on four empirical studies of interactive performances carried out in collaboration with artists, performers, and designers. These studies focus on: (i) investigating scenarios of sensor-based and bodily tracking technologies in interactive performances, (ii) investigating how professional guitar players experience and express the smart qualities of a smart guitar in their artistic practices, (iii) investigating the audience's sense of immersion in a mixed-reality performance through introducing the concept of friction, and (iv) exploring frictions as a design resource in sketching scenarios of performances with VR. Two main methodological approaches were used throughout this research: Research through Design (RtD) and performance–led research in the wild. Beyond the result of these investigations, this thesis also presents the following contributions. First by presenting insights and knowledge generated through explorations of the incorporation of interactive technologies in performances through ideation, through studies of technology in use, and through design activities. This includes discussions around artists’ and audience members’ experience of technology including novel opportunities of interaction and participation, their collaborative roles and their agency and control within artistic productions. Second, by introducing friction as a Strong Concept to analyse interactions within a mixed-reality performance and to discuss how immersion is experienced throughout such performances. Finally by further developing the concept of friction through the collaborative design and staging of a novel mixed-reality performance
Bodystorming for Movement-Based Interaction Design
Get PDFAfter a decade of movement-based interaction in human–computer interaction, designing for the moving body still remains a challenge. Research in this field requires methods to help access, articulate, and harness embodied experiences in ways that can inform the design process. To address this challenge, this article appropriates bodystorming, an embodied ideation method for movement-based interaction design. The proposed method allows for early consideration of the physical, collocated, and social aspects of a designed activity as illustrated with two explorative workshops in different application domains: interactive body games and interactive performances. Using a qualitative methods approach, we used video material from the workshops, feedback from participants, and our own experience as participants and facilitators to outline important characteristics of the bodystorming method in the domain of movement-based interaction. The proposed method is compared with previous ones and application implications are discussed.peerReviewe
Performing with Technology
No full textThis research explores the use of technology in Mixed-Reality Performance, and how novel interactive technologies (VR, IoT, Bio-Data) can be used in designing such performances. Additionally, I explore the potential of these technologies to increase audience' interaction with the performance. The studies presented in this paper are still under development and mainly focus on three novel technologies within performances; Virtual Reality, Bio-Data and environmental IoT.</p
The Normal Natural Troubles of Virtual Reality in Mixed-Reality Performances
No full textPerforming with technology is a complex and challenging task. Artists who use novel technologies, such as Virtual Reality, have to develop strategies of monitoring, maintenance, and recovery from errors with as minimal impact on the ongoing performance as possible. In this paper we draw on two case studies of mixed-reality performances and document strategies of Stage Managing VR Performance, Choreographing for Cables, Consistency & Charging, Improvising Interventions, and Priming Participants. We discuss how these practices expose areas ripe with potential for tool development, and how they can also be used to inform the design of interaction with other technologies, such as the Internet of Things.</p
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
