Cross-device media: a review of second screening and multi-device television

Television viewers interacting with second screens has become a common sight in the modern living room. Such activities are a mixture of related, semi-related, and non-related browsing of content. This growing trend is revolutionising the way that broadcasters think about their content. Through the envisioned connected home, driven by end-to-end IP connected networks, television content creators and app developers are now considering the design space for multi-device, interactive experiences. In this review paper, we consider the pre-digital beginnings of such scenarios, and progress to discuss how the introduction of mobile devices has affected the TV viewing experience. We discuss dual-screen usage over a variety of contexts in the connected home, with a focus on ‘designed’ dual-screen experiences such as companion applications. We conclude with reflections on the future of this area so that app developers, broadcasters, and academics may push further the space and improve future dual- and multi-screen experiences

Towards an explication of the presence effects on information processing and persuasion: A construal level framework

Dissatisfied with the existing theoretical account of the effects of presence on the mode of information processing (i.e., heuristic vs. systematic processing) and how this leads to persuasion in the context of mediated communication, the current study suggests an alternative framework that could provide an efficient and reasonable way of understanding the underlying psychological mechanism of the presence effects on persuasion. Drawing on presence theory, construal level theory, and the dual process model of persuasion, this study proposes a conceptual model that posits construal level as a key variable that mediates the effects of presence on the mode of information processing. Specifically, on the basis of the conceptual overlap between psychological distance and presence, which are respectively represented as key constructs in construal level theory and presence theory, this study proposes that a sense of presence has the potential to replace the role of psychological distance in the construal level theory and consequently prime a certain level of construal (i.e., the extent to which people’s thinking is abstract or concrete). Additionally, the conceptual similarity between the construal level in the construal level theory and the dual process model is supposed to lead people to apply the primed level of construal in processing information. In this framework, construal level is posited as a key factor that could mediate the relationship between the degree to which people experience a sense of presence and the mode of information processing. This study also attempts to provide a theoretical understanding of how this framework will serially influence the formation of trust and persuasion (i.e., behavioral intention). Guided by the empirical evidence from earlier studies, heuristic and systematic processing are predicted to respectively increase the degree to which people form affective trust towards brand and cognitive trust towards advertising product information. Consequently, persuasion is predicted to occur through both cognitive trust towards advertising product information and affective trust towards brand, as affect and cognition are intertwined. In order to validate this conceptual model, a two (ad presentation mode: video vs. text) x two (ad type: location-based advertising vs. traditional advertising) between-subjects experiment (N = 180) was conducted in a recent advertising context―i.e., location-based advertising. Consistent with the predictions based on this framework, the results showed that construal level plays a significant role in mediating the effects of presence and social presence on the mode of information processing. In addition, the amount of heuristic and systematic processing, determined by the construal level primed by a sense of presence and social presence, was positively associated with the degree to which people form affective trust towards brand and cognitive trust towards advertising product information. Consequently, both affective trust towards brand and cognitive trust towards advertising product information, formed through heuristic and systematic processing, positively influenced participants’ behavioral (purchase) intention. Through partial least squares structural equation modeling, this framework was statistically validated. Further theoretical implications of this framework are discussed

Infrastructuring for cultural commons

In this doctoral dissertation, I inquire into the ways in which Participatory Design (PD) and digital design endeavors can contribute to wider public access to, and use of, digital cultural heritage. I advocate for an approach according to which digital cultural heritage is arranged and understood as cultural commons, and for more collaborative modes of social care for and governance of the commons. In addition to the empirically grounded findings and proposals contained in six individual research articles, I develop a theoretical framework that combines scholarship on Information Infrastructures, Commons and PD. Against this framework I interrogate how the information infrastructures and conditions that surround digital cultural heritage can be active in constructing and contributing to cultural commons. While doing this, I draw attention to the gap that exists between on the one hand official institutional digital cultural heritage collections, systems and practices, and on the other hand the digital platforms and practices through which everyday people create, curate and share digital cultural works. In order to understand how to critically and productively bridge this gap, I present insights gained from conducting three design research cases that engage both cultural heritage institutions and everyday media users. Building upon this empirical work, and latching on to scholarship on the notion of infrastructuring, I propose four infrastructuring strategies for cultural commons: probing and building upon the installed base, stimulating and simulating design and use through gateways, producing and pooling shared resources, and, lastly, fostering and shaping a commons culture that supports commoning. In exploring these strategies, I map the territory between commons and infrastructuring, and connect these notions to the PD tradition. I do so to sketch the design principles for a design orientation, commons design. I assert that these principles can be useful for advancing PD, and can inform future initiatives, aid in identifying infrastructural challenges, and in finding and confirming an orientation to participatory design activities. Drawing on my practical design work, I discuss requirements for professional designers operating on commons frameworks and with collective action. By doing this, my dissertation not only breaks new theoretical ground through advancing theoretical considerations relevant to contemporary design research, especially the field of PD, but also contributes practical implications useful for professional digital media design practice, especially for designers working in the fields of digital culture and cultural heritage

Deficit Frame Dangers

Civil rights advocates have long viewed litigation as an essential, if insufficient, catalyst of social change. In part, it is. But in critical respects that remain underexplored in legal scholarship, civil rights litigation can hinder short- and long-term projects of racial justice. Specifically, certain civil rights doctrines reward plaintiffs for emphasizing community deficits—or what I term a “deficit frame.” Legal doctrine, in other words, invites legal narratives that track, activate, and reinforce pernicious racial stereotypes. This dynamic, even in the context of well-intended litigation, risks entrenching conditions that drive racial inequality—including the conditions that litigation is often intended to address. To concretize the theory, this Article explores how deficit frames can influence the behavior of four key constituencies who impact—and often undermine—the pursuit of educational equality

Gender and Human-Machine Communication: Where Are We?

In this introduction to the fifth volume of the journal Human-Machine Communication, we present and discuss the five articles focusing on gender and human-machine communication. In this essay, we will analyze the theme of gender, including how this notion has historically and politically been set up, and for what reasons. We will start by considering gender in in-person communication, then we will progress to consider what happens to gender when it is mediated by the most important ICTs that preceded HMC: the telephone, mobile phone, and computer-mediated communication (CMC). We outline the historical framework necessary to analyze the last section of the essay, which focuses on gender in HMC. In the conclusion, we will set up some final sociological and political reflections on the social meaning of these technologies for gender and specifically for women

User interface design considerations for emerging input technologies in iTV

Streaming media and interactive television viewing experiences are becoming more commonplace with the introduction of services such as Netflix Streaming, the Apple TV, and Google TV aided by the increase adoption of broadband internet. As these services make their way into the living room, and developers struggle to accommodate more complex interaction requirements, new input methods and interfaces need to be developed. Current interfaces for controlling interactive TV and media management have typically been designed for the desktop and laptop experience, using conventional input devices like a trackpad, mouse and keyboard. These techniques are difficult to reconcile with the typical TV viewing experience. We designed an experiment to test a representative interactive TV interface with a number of emerging input technologies like the Nintendo Wiimote, Microsoft Kinect and tablet applications. We measured user performance with these devices while encumbered by a beverage and plate of food in order to simulate a living room experience. We found that while most of these technologies are suitable for navigating an Interactive TV experience, their use challenges us to rethink the user experience, and places limitations on things like button size and placement, as well as the types of UI widgets we can use. We hope these guidelines and heuristics will help in the design of future interactive TV experiences, as well as the development of novel interaction techniques for the TV viewing experience

Qualitätstaxonomie für skalierbare Algorithmen von Free Viewpoint Video Objekten

Diese Dissertation beabsichtigt einen Beitrag zur Qualitätsbeurteilung von Algorithmen für Bildanalyse und Bildsynthese im Anwendungskontext Videokommunikationssysteme zu leisten. In der vorliegenden Arbeit werden Möglichkeiten und Hindernisse der nutzerzentrierten Definition von subjektiver Qualitätswahrnehmung in diesem speziellen Anwendungsfall untersucht. Qualitätsbeurteilung von aufkommender Visualisierungs-Technologie und neuen Verfahren zur Erzeugung einer dreidimensionalen Repräsentation unter der Nutzung von Bildinformation zweier Kameras für Videokommunikationssysteme wurde bisher noch nicht umfangreich behandelt und passende Ansätze dazu fehlen. Die Herausforderungen sind es qualitätsbeeinflussende Faktoren zu definieren, passende Maße zu formulieren, sowie die Qualitätsevaluierung mit den Erstellungsalgorithmen, welche noch in Entwicklung sind, zu verbinden. Der Vorteil der Verlinkung von Qualitätswahrnehmung und Servicequalität ist die Unterstützung der technischen Realisierungsprozesse hinsichtlich ihrer Anpassungsfähigkeit (z.B. an das vom Nutzer verwendete System) und Skalierbarkeit (z.B. Beachtung eines Aufwands- oder Ressourcenlimits) unter Berücksichtigung des Endnutzers und dessen Qualitätsanforderungen. Die vorliegende Arbeit beschreibt den theoretischen Hintergrund und einen Vorschlag für eine Qualitätstaxonomie als verlinkendes Modell. Diese Arbeit beinhaltet eine Beschreibung des Projektes Skalalgo3d, welches den Rahmen der Anwendung darstellt. Präsentierte Ergebnisse bestehen aus einer systematischen Definition von qualitätsbeeinflussenden Faktoren inklusive eines Forschungsrahmens und Evaluierungsaktivitäten die mehr als 350 Testteilnehmer inkludieren, sowie daraus heraus definierte Qualitätsmerkmale der evaluierten Qualität der visuellen Repräsentation für Videokommunikationsanwendungen. Ein darauf basierendes Modell um diese Ergebnisse mit den technischen Erstellungsschritten zu verlinken wird zum Schluss anhand eines formalisierten Qualitätsmaßes präsentiert. Ein Flussdiagramm und ein Richtungsfeld zur grafischen Annäherung an eine differenzierbare Funktion möglicher Zusammenhänge werden daraufhin für weitere Untersuchungen vorgeschlagen.The thesis intends to make a contribution to the quality assessment of free viewpoint video objects within the context of video communication systems. The current work analyzes opportunities and obstacles, focusing on users' subjective quality of experience in this special case. Quality estimation of emerging free viewpoint video object technology in video communication has not yet been assessed and adequate approaches are missing. The challenges are to define factors that influence quality, to formulate an adequate measure of quality, and to link the quality of experience to the technical realization within an undefined and ever-changing technical realization process. There are two advantages of interlinking the quality of experience with the quality of service: First, it can benefit the technical realization process, in order to allow adaptability (e.g., based on systems used by the end users). Second, it provides an opportunity to support scalability in a user-centered way, e.g., based on a cost or resources limitation. The thesis outlines the theoretical background and introduces a user-centered quality taxonomy in the form of an interlinking model. A description of the related project Skalalgo3d is included, which offered a framework for application. The outlined results consist of a systematic definition of factors that influence quality, including a research framework, and evaluation activities involving more than 350 participants. The thesis includes the presentation of quality features, defined by evaluations of free viewpoint video object quality, for video communication application. Based on these quality features, a model that links these results with the technical creation process, including a formalized quality measure, is presented. Based on this, a flow chart and slope field are proposed. These intend the visualization of these potential relationships and may work as a starting point for further investigations thereon and to differentiate relations in form of functions
