Collaborative Multimedia Systems: Synthesis of Media Objects

When a group I_1,... ,I_n of individuals wishes to collaboratively construct a complex multimedia document, the first requirement is that they be able to manipulate media-objects created by one another. For instance, if individual I_j wishes to access some media objects present at participant I_k's site, he must be able to; (1) retrieve this object from across the network, (2) ensure that the object is in a form that is compatible with the viewing/editing resources he has available at his node, and (3) ensure that the object has the desired quality (such as image size and resolution). Furthermore, he must be able to achieve these goals at the lowest possible cost. In this paper, we develop a theory of media objects, and present optimal algorithms for collaborative object sharing/synthesis of the sort envisaged above. We then extend the algorithms to incorporate quality constraints (such as image size) as well as distribution across multiple nodes. The theoretical model is validated by an experimental implementation that supports the theoretical results. (Also cross-referenced as UMIACS-TR-96-8

Virtual Architecture: Designing and Directing Curriculum-Based Telecomputing

Is it worth it, all this Internet stuff? Worth the time and energy it takes? Worth it because your students will learn more? Worth it because you\u27ll be a better teacher? The answer to these questions-yes and no-can be found in this readable, conversational, practical, and slyly revolutionary work. The author proposes that integrating computer-mediated technology into your classroom is well worth it if accomplished in a way that helps new and worthwhile things happen there. And then she shows you how to do just that. You\u27ll begin building with a flexible framework-clear, strong, and simple activity structures-that becomes your foundation for designing and implementing powerful curriculum-based telecomputing projects. Don\u27t expect a project directory, general reference, or manual. This is a book you\u27ll read from start to finish and be glad you did. It\u27s worth it

Montage As A Participatory System: Interactions with the Moving Image

Full version unavailable due to 3rd party copyright restrictionsRecent developments in network culture suggest a weakening of hierarchical narratives of power and representation. Online technologies of distributed authorship appear to nurture a complex, speculative, contradictory and contingent realism. Yet there is a continuing deficit where the moving image is concerned, its very form appearing resistant to the dynamic throughputs and change models of real-time interaction. If the task is not to suspend but encourage disbelief as a condition in the user, how can this be approached as a design problem? In the attempt to build a series of design projects suggesting open architectures for the moving image, might a variety of (pre-digital) precursors from the worlds of art, architecture and film offer the designer models for inspiration or adaptation? A series of projects have been undertaken. Each investigates the composite moving image, specifically in the context of real-time computation and interaction. This arose from a desire to interrogate the qualia of the moving image within interactive systems, relative to a range of behaviours and/or observer positions, which attempt to situate users as conscious compositors. This is explored in the thesis through reflecting on a series of experimental interfaces designed for real time composition in performance, exhibition and online contexts

A Corpus-assisted Discourse Analysis of Music-related Practices Discussed within Chipmusic.org

abstract: This study examined discussion forum posts within a website dedicated to a medium and genre of music (chiptunes) with potential for music-centered making, a phrase I use to describe maker culture practices that revolve around music-related purposes. Three research questions guided this study: (1) What chiptune-related practices did members of chipmusic.org discuss between December 30th, 2009 and November 13th, 2017? (2) What do chipmusic.org discussion forum posts reveal about the multidisciplinary aspects of chiptunes? (3) What import might music-centered making evident within chipmusic.org discussion forum posts hold for music education? To address these research questions, I engaged in corpus-assisted discourse analysis tools and techniques to reveal and analyze patterns of discourse within 245,098 discussion forum posts within chipmusic.org. The analysis cycle consisted of (a) using corpus analysis techniques to reveal patterns of discourse across and within data consisting of 10,892,645 words, and (b) using discourse analysis techniques for a close reading of revealed patterns. Findings revealed seven interconnected themes of chiptune-related practices: (a) composition practices, (b) performance practices, (c) maker practices, (d) coding practices, (e) entrepreneurial practices, (f), visual art practices, and (g) community practices. Members of chipmusic.org primarily discussed composing and performing chiptunes on a variety of instruments, as well as through retro computer and video game hardware. Members also discussed modifying and creating hardware and software for a multitude of electronic devices. Some members engaged in entrepreneurial practices to promote, sell, buy, and trade with other members. Throughout each of the revealed themes, members engaged in visual art practices, as well as community practices such as collective learning, collaborating, constructive criticism, competitive events, and collective efficacy. Findings suggest the revealed themes incorporated practices from a multitude of academic disciplines or fields of study for music-related purposes. However, I argue that many of the music-related practices people discussed within chipmusic.org are not apparent within music education discourse, curricula, or standards. I call for an expansion of music education discourse and practices to include additional ways of being musical through practices that might borrow from multiple academic disciplines or fields of study for music-related purposes.Dissertation/ThesisDoctoral Dissertation Music Education 201

Understanding Collaborative Sensemaking for System Design — An Investigation of Musicians\u27 Practice

There is surprisingly little written in information science and technology literature about the design of tools used to support the collaboration of creators. Understanding collaborative sensemaking through the use of language has been traditionally applied to non-work domains, but this method is also well-suited for informing hypotheses about the design collaborative systems. The presence of ubiquitous, mobile technology, and development of multi-user virtual spaces invites investigation of design which is based on naturalistic, real world, creative group behaviors, including the collaborative work of musicians. This thesis is considering the co-construction of new (musical) knowledge by small groups. Co-construction of new knowledge is critical to the definition of an information system because it emphasizes coordination and resource sharing among group members (versus individual members independently doing their own tasks and only coming together to collate their contributions as a final product). This work situates the locus of creativity on the process itself, rather than on the output (the musical result) or the individuals (members of the band). This thesis describes a way to apply quantitative observations to inform qualitative assessment of the characteristics of collaborative sensemaking in groups. Conversational data were obtained from nine face-to-face collaborative composing sessions, involving three separate bands producing 18 hours of recorded interactions. Topical characteristics of the discussion, namely objects, plans, properties and performance; as well as emergent patterns of generative, evaluative, revision, and management conversational acts within the group were seen as indicative of knowledge construction. The findings report the use of collaborative pathways: iterative cycles of generation, evaluation and revision of temporary solutions used to move the collaboration forward. In addition, bracketing of temporary solutions served to help collaborators reuse content and offload attentional resources. Ambiguity in language, evaluation criteria, goal formation, and group awareness meant that existing knowledge representations were insufficient in making sense of incoming data and necessitated reformulating those representations. Further, strategic use of affective language was found to be instrumental in bridging knowledge gaps. Based on these findings, features of a collaborative system are proposed to help in facilitating sensemaking routines at various stages of a creative task. This research contributes to the theoretical understanding of collaborative sensemaking during non-work, creative activities in order to inform the design of systems for supporting these activities. By studying an environment which forms a potential microcosm of virtual interaction between groups, it provides a framework for understanding and automating collaborative discussion content in terms of the features of dialogue

Perceptual fail: Female power, mobile technologies and images of self

Like a biological species, images of self have descended and modified throughout their journey down the ages, interweaving and recharging their viability with the necessary interjections from culture, tools and technology. Part of this journey has seen images of self also become an intrinsic function within the narratives about female power; consider Helen of Troy “a face that launched a thousand ships” (Marlowe, 1604) or Kim Kardashian (KUWTK) who heralded in the mass mediated ‘selfie’ as a social practice. The interweaving process itself sees the image oscillate between naturalized ‘icon’ and idealized ‘symbol’ of what the person looked like and/or aspired to become. These public images can confirm or constitute beauty ideals as well as influence (via imitation) behaviour and mannerisms, and as such the viewers belief in the veracity of the representative image also becomes intrinsically political manipulating the associated narratives and fostering prejudice (Dobson 2015, Korsmeyer 2004, Pollock 2003). The selfie is arguably ‘a sui generis,’ whilst it is a mediated photographic image of self, it contains its own codes of communication and decorum that fostered the formation of numerous new digital communities and influenced new media aesthetics . For example the selfie is both of nature (it is still a time based piece of documentation) and known to be perceptually untrue (filtered, modified and full of artifice). The paper will seek to demonstrate how selfie culture is infused both by considerable levels of perceptual failings that are now central to contemporary celebrity culture and its’ notion of glamour which in turn is intrinsically linked (but not solely defined) by the province of feminine desire for reinvention, transformation or “self-sexualisation” (Hall, West and McIntyre, 2012). The subject, like the Kardashians or selfies, is divisive. In conclusion this paper will explore the paradox of the perceptual failings at play within selfie culture more broadly, like ‘Reality TV’ selfies are infamously fake yet seem to provide Debord’s (1967) illusory cultural opiate whilst fulfilling a cultural longing. Questions then emerge when considering the narrative impact of these trends on engendered power structures and the traditional status of illusion and narrative fiction

MediaSync: Handbook on Multimedia Synchronization

This book provides an approachable overview of the most recent advances in the fascinating field of media synchronization (mediasync), gathering contributions from the most representative and influential experts. Understanding the challenges of this field in the current multi-sensory, multi-device, and multi-protocol world is not an easy task. The book revisits the foundations of mediasync, including theoretical frameworks and models, highlights ongoing research efforts, like hybrid broadband broadcast (HBB) delivery and users' perception modeling (i.e., Quality of Experience or QoE), and paves the way for the future (e.g., towards the deployment of multi-sensory and ultra-realistic experiences). Although many advances around mediasync have been devised and deployed, this area of research is getting renewed attention to overcome remaining challenges in the next-generation (heterogeneous and ubiquitous) media ecosystem. Given the significant advances in this research area, its current relevance and the multiple disciplines it involves, the availability of a reference book on mediasync becomes necessary. This book fills the gap in this context. In particular, it addresses key aspects and reviews the most relevant contributions within the mediasync research space, from different perspectives. Mediasync: Handbook on Multimedia Synchronization is the perfect companion for scholars and practitioners that want to acquire strong knowledge about this research area, and also approach the challenges behind ensuring the best mediated experiences, by providing the adequate synchronization between the media elements that constitute these experiences
