Second Life : representation and remediation of social space

Ao longo da última década os jogos online e as plataformas sociais têm-se tornado cada vez mais populares, tendo vindo a contribuir para o desenvolvimento da internet. Os jogos online multiplayer têm conquistado cada vez mais utilizadores. Estes têm como locus a realidade virtual e como objetivo a recriação de um novo mundo. Um exemplo deste tipo de jogos é o Second Life, um jogo social que conta com um elevado número de utilizadores – cerca de 31 milhões de utilizadores registados. Esta plataforma foi desenvolvida pela Linden Lab e reúne as características de um mundo virtual: é um cenário digital tridimensional, no qual utilizadores de todo o mundo, representados por avatares, interagem em tempo real formando diversos tipos de redes sociais. Uma das suas características distintivas é o facto de 99% do conteúdo existente dentro do espaço virtual ter sido desenvolvido pelos utilizadores. Os jogadores, denominados residentes, estão a contribuir não só na construção do espaço, mas também para o desenvolvimento social deste mundo virtual. Para além disto, existem mais quatro características que tornam o Second Life um objeto de estudo interessante: todos os avatares são controlados por seres humanos em tempo real; o reconhecimento de direitos de propriedade intelectual; a existência de uma micro-moeda – o Linden Dollar; e o facto de todos os jogadores terem acesso a ferramentas básicas de construção, e à linguagem de programação desenvolvida pela Linden Lab, a Linden Scripting Language, essenciais para criar objetos. O Second Life é um espaço colaborativo e participativo que, apesar de ser um jogo, oferece aos seus utilizadores uma experiência muito diferente da vivida nos videojogos tradicionais. Por ser um jogo do tipo caixa de areia os jogadores podem estabelecer uma relação diferente com esta plataforma, pois podem contribuir para as diversas dimensões da vida dentro do jogo. Devido às suas características, este mundo virtual tem despertado o interesse de investigadores de diferentes áreas que têm procurado perceber o seu impacto para a interação social, educação, economia, lei, e indústrias criativas. No entanto, tendo em conta que o ‘espaço’ é um elemento fulcral na investigação em Ciências Humanas e uma das áreas priveligiadas pela European Science Foundation para a investigação em Ciências Sociais e Humanas, há, ainda, a necessidade de perceber como é que este espaço digital está a ser desenvolvido, e que narrativas culturais o estão a moldar. Uma vez que o Second Life reflete a importância dos mundos virtuais para a interação online, torna-se fundamental compreender que impacto a virtualização das relações sociais pode ter para a interação interpessoal e para o desenvolvimento de um novo tipo de ‘comunidades imaginadas’. A presente investigação centra-se no Second Life e procura perceber de que forma poderá este novo espaço de interação estar a contribuir para o aparecimento de uma nova dimensão social. Uma dimensão resultante das possibilidades oferecidas por uma plataforma tecnológica apenas disponível através da internet, combinadas com o potencial criativo dos seus utilizadores. Com o intuito de contribuir para um melhor entendimento do potencial sociocultural deste mundo virtual, este estudo tem como base uma investigação empírica desenvolvida a partir de uma metodologia qualitativa específica para o estudo de comunidades online, a netnografia. Os métodos de recolha de dados adotados são: observação participante, auto-netnografia, entrevista e análise de conteúdo dos perfis dos utilizadores entrevistados. Os dados são analisados seguindo uma abordagem indutiva. A principal hipótese deste estudo centra-se na premissa que se o Second Life é um mundo virtual que está a ser coproduzido pela Linden Lab e pelos utilizadores, é provável que o envolvimento dos residentes com a realidade virtual resulte na criação de um sistema de representação re-mediado. Partindo desta hipótese, os objetivos principais desta investigação são confirmar se de facto os mundos virtuais estão a ser usados para representar e re-mediar o espaço social, e perceber que efeito isto tem nos jogadores. Uma das principais conclusões retiradas prende-se com o facto de os utilizadores estarem a tirar partido deste mundo virtual para renegociarem os modelos socioculturais que informam as suas ‘primeiras vidas’. Após a análise da relação que os utilizadores estabelecem com o espaço virtual, com os seus próprios avatares e entre si, concluiu-se que são três as principais narrativas culturais que estão a resultar das experiências vividas pelos residentes deste mundo virtual. As primeiras intrinsecamente relacionadas com a organização geográfica da vida humana – narrativas de espaço; as segundas, com a necessidade de nos compreendermos a nós mesmos, narrativas identitárias; e as terceiras, com o facto de os seres humanos serem na sua essência seres sociais, narrativas resultantes da interação social com outros residentes. A ‘re-mediação’ de narrativas culturais dentro de um ambiente online, anónimo e flexível evidencia a necessidade que os seres humanos têm de reconhecer os espaços sociais que frequentam, de modo a envolverem-se e atribuírem significado às experiências digitais vividas.Over the past decade online games and social platforms became very popular and contributed to the internet development. The massive multiplayer online games have conquered a high number of users. The locus of these games is virtual reality, and the main goal is the recreation of a new world. Second Life is one of these games, a tridimensional social platform which counts with a high number of users – around 31 million registered users. It was developed by Linden Lab and it assembles the main characteristics of a virtual worlds: it is a tridimensional digital setting where users from all over the world represented by avatars interact in real time, and develop diversified social networks. One of its main characteristics is the prevalence of prodused content – 99 per cent of the content existing in-world was created by residents. Players, designated residents, are not only contributing to the space construction, but also to the social development of this virtual world. Apart from this, there are four more characteristics that make this multiuser environment interesting as an object of study: all the avatars existent in-world are playing characters controlled by human beings in real time; the recognition of intellectual property rights; the existence of a micro-currency – the Linden Dollar; and all the players have access to simple building tools, and to the Linden Scripting Language, which are essential to create objects. Second Life is a collaborative and participative space that, despite being a game, offers its users a very different experience from that lived within traditional video games. Because it is a sandbox game players are able to establish a different kind of relationship with the platform, once they can contribute to the different dimensions of the life in-world. Due to its intrinsic characteristics, this virtual world has caught the attention of researchers from several areas that showed interest in understanding the impact this virtual world may have in social interaction, education, economy, law and creative industries. Notwithstanding, considering that ‘space’ is a key element in the Humanities, and one of the privileged areas by the European Science Foundation for the research in Social Sciences and Humanities, it is necessary to better understand how this digital space is being developed, and which cultural narratives are shaping it. Since Second Life reflects the relevance of virtual worlds to online interaction, it is essential to comprehend the impact that the ‘virtualization’ of social relationships may have for interpersonal interaction, and for the emergence of a new type of ‘imagined communities’. The present research is centered on Second Life and looks forward to understand how this new interaction space could be contributing to the emergence of a new social dimension. A dimension resulting from the possibilities offered by a technology platform only available through the internet, combined with the creative potential of its users. In order to contribute to a better understanding of the sociocultural potential of this virtual world, this study is grounded on an empirical research based on a specific qualitative methodology for studying online communities, the netnography. The methods adopted for data collection are: participant observation, auto-netnography, interview, and content analysis of the interviewees’ profiles. The data collected is analyzed through an inductive approach. The main hypothesis framing this research is the premise that if Second Life is a virtual world that is being prodused by its residents, it is probable that users’ involvement with the virtual reality would result in the creation of a remediated system of representation. Based on this hypothesis, the main goals then are to confirm if virtual worlds are indeed representing and remediating social space, and to understand the effect this has on players. One of the main conclusions reached is that the users are taking advantage of the affordances of this virtual world to renegotiate the sociocultural models that frame their first lives. Through the analysis of the relationship users are establishing with the virtual space, with their own avatars, and with each other, it is concluded that there are three main cultural narratives emerging from the in-world experience lived by the residents. The first intrinsically related with the geographical organization of human life – spatial narratives; the second, with the need to make sense of oneself – narratives of identity; and the third, with the fact that humans are social beings in essence – social interaction narratives resulting from the interaction with other residents. The remediation of cultural narratives into an online, anonymous, and flexible environment evinces the need humans have for recognizable social spaces in order to be able to get involved and attribute meaning to the lived digital experiences

Immersion and interaction: Creating virtual 3d worlds for stage performances

This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.This thesis formulates an approach towards the creation of a gesture activated and body movement controlled real time virtual 3d world in a dance performance context. It investigates immersion and navigation techniques derived from modern video games and methodologies and proposes how they can be used to further involve a performer into a virtual space as well as simultaneously offer a stimulating visual spectacle for an audience. The argument presented develops through practice-based methodology and artistic production strategies in interdisciplinary and collaborative contexts. Two choreographic performance/installations are used as cases studies to demonstrate in practice the proposed methodologies. First, the interactive dance work Suna No Onna, created in collaboration with Birringer/Danjoux and the Dap Lab, investigates the use of interactive pre-rendered animations in a real time setting and in real time by incorporating wearable sensors in the performance. Secondly, the potentials offered by the sensor technology and real time rendering engines led to the “creation scene", a key scene in the choreographic installation UKIYO (Moveable Worlds). This thesis investigates the design, creation and interaction qualities of virtual 3d spaces by exploring the potentialities offered by a shared space, between an intelligent space and a dancer in a hybrid world. The methodology applied uses as a theoretical base the phenomenological approach of Merleau-Ponty and Mark Hansen‟s mixed reality paradigm proposing the concept of the “space schema", a system which replicates and embeds proprioception, perception and motility into the space fabric offering a world which “lives”, functions and interacts with the performer. The outcome of the research is the generation of an interactive, non-linear, randomized 3d virtual space that collaborates with a technologically embedded performer in creating a 3d world which evolves and transforms, driven by the performer‟s intention and agency. This research contributes to the field of interactive performance art by making transparent the methodology, the instruments and the code used, in a non-technical terminology, making it accessible for both team members with less technological expertise as well as artists aspiring to engage interactive 3d media promoting further experimentation and conceptual discussions

To Affinity and Beyond: Interactive Digital Humans as a Human Computer Interface

The field of human computer interaction is increasingly exploring the use of more natural, human-like user interfaces to build intelligent agents to aid in everyday life. This is coupled with a move to people using ever more realistic avatars to represent themselves in their digital lives. As the ability to produce emotionally engaging digital human representations is only just now becoming technically possible, there is little research into how to approach such tasks. This is due to both technical complexity and operational implementation cost. This is now changing as we are at a nexus point with new approaches, faster graphics processing and enabling new technologies in machine learning and computer vision becoming available. I articulate the issues required for such digital humans to be considered successfully located on the other side of the phenomenon known as the Uncanny Valley. My results show that a complex mix of perceived and contextual aspects affect the sense making on digital humans and highlights previously undocumented effects of interactivity on the affinity. Users are willing to accept digital humans as a new form of user interface and they react to them emotionally in previously unanticipated ways. My research shows that it is possible to build an effective interactive digital human that crosses the Uncanny Valley. I directly explore what is required to build a visually realistic digital human as a primary research question and I explore if such a realistic face provides sufficient benefit to justify the challenges involved in building it. I conducted a Delphi study to inform the research approaches and then produced a complex digital human character based on these insights. This interactive and realistic digital human avatar represents a major technical undertaking involving multiple teams around the world. Finally, I explored a framework for examining the ethical implications and signpost future research areas

3D (embodied) projection mapping and sensing bodies : a study in interactive dance performance

This dissertation identifies the synergies between physical and virtual environments when designing for immersive experiences in interactive dance performances. The integration of virtual information in physical space is transforming our interactions and experiences with the world. By using the body and creative expression as the interface between real and virtual worlds, dance performance creates a privileged framework to research and design interactive mixed reality environments and immersive augmented architectures. The research is primarily situated in the fields of visual art and interaction design. It combines performance with transdisciplinary fields and intertwines practice with theory. The theoretical and conceptual implications involved in designing and experiencing immersive hybrid environments are analyzed using the reality–virtuality continuum. These theories helped frame the ways augmented reality architectures are achieved through the integration of dance performance with digital software and reception displays. They also helped identify the main artistic affordances and restrictions in the design of augmented reality and augmented virtuality environments for live performance. These pervasive media architectures were materialized in three field experiments, the live dance performances. Each performance was created in three different stages of conception, design and production. The first stage was to “digitize” the performer’s movement and brain activity to the virtual environment and our system. This was accomplished through the use of depth sensor cameras, 3D motion capture, and brain computer interfaces. The second stage was the creation of the computational architecture and software that aggregates the connections and mapping between the physical body and the spatial dynamics of the virtual environment. This process created real-time interactions between the performer’s behavior and motion and the real-time generative computer 3D graphics. Finally, the third stage consisted of the output modality: 3D projector based augmentation techniques were adopted in order to overlay the virtual environment onto physical space. This thesis proposes and lays out theoretical, technical, and artistic frameworks between 3D digital environments and moving bodies in dance performance. By sensing the body and the brain with the 3D virtual environments, new layers of augmentation and interactions are established, and ultimately this generates mixed reality environments for embodied improvisational self-expression.Radio-Television-Fil

Enhanced Virtuality: Increasing the Usability and Productivity of Virtual Environments

Mit stetig steigender Bildschirmauflösung, genauerem Tracking und fallenden Preisen stehen Virtual Reality (VR) Systeme kurz davor sich erfolgreich am Markt zu etablieren. Verschiedene Werkzeuge helfen Entwicklern bei der Erstellung komplexer Interaktionen mit mehreren Benutzern innerhalb adaptiver virtueller Umgebungen. Allerdings entstehen mit der Verbreitung der VR-Systeme auch zusätzliche Herausforderungen: Diverse Eingabegeräte mit ungewohnten Formen und Tastenlayouts verhindern eine intuitive Interaktion. Darüber hinaus zwingt der eingeschränkte Funktionsumfang bestehender Software die Nutzer dazu, auf herkömmliche PC- oder Touch-basierte Systeme zurückzugreifen. Außerdem birgt die Zusammenarbeit mit anderen Anwendern am gleichen Standort Herausforderungen hinsichtlich der Kalibrierung unterschiedlicher Trackingsysteme und der Kollisionsvermeidung. Beim entfernten Zusammenarbeiten wird die Interaktion durch Latenzzeiten und Verbindungsverluste zusätzlich beeinflusst. Schließlich haben die Benutzer unterschiedliche Anforderungen an die Visualisierung von Inhalten, z.B. Größe, Ausrichtung, Farbe oder Kontrast, innerhalb der virtuellen Welten. Eine strikte Nachbildung von realen Umgebungen in VR verschenkt Potential und wird es nicht ermöglichen, die individuellen Bedürfnisse der Benutzer zu berücksichtigen. Um diese Probleme anzugehen, werden in der vorliegenden Arbeit Lösungen in den Bereichen Eingabe, Zusammenarbeit und Erweiterung von virtuellen Welten und Benutzern vorgestellt, die darauf abzielen, die Benutzerfreundlichkeit und Produktivität von VR zu erhöhen. Zunächst werden PC-basierte Hardware und Software in die virtuelle Welt übertragen, um die Vertrautheit und den Funktionsumfang bestehender Anwendungen in VR zu erhalten. Virtuelle Stellvertreter von physischen Geräten, z.B. Tastatur und Tablet, und ein VR-Modus für Anwendungen ermöglichen es dem Benutzer reale Fähigkeiten in die virtuelle Welt zu übertragen. Des Weiteren wird ein Algorithmus vorgestellt, der die Kalibrierung mehrerer ko-lokaler VR-Geräte mit hoher Genauigkeit und geringen Hardwareanforderungen und geringem Aufwand ermöglicht. Da VR-Headsets die reale Umgebung der Benutzer ausblenden, wird die Relevanz einer Ganzkörper-Avatar-Visualisierung für die Kollisionsvermeidung und das entfernte Zusammenarbeiten nachgewiesen. Darüber hinaus werden personalisierte räumliche oder zeitliche Modifikationen vorgestellt, die es erlauben, die Benutzerfreundlichkeit, Arbeitsleistung und soziale Präsenz von Benutzern zu erhöhen. Diskrepanzen zwischen den virtuellen Welten, die durch persönliche Anpassungen entstehen, werden durch Methoden der Avatar-Umlenkung (engl. redirection) kompensiert. Abschließend werden einige der Methoden und Erkenntnisse in eine beispielhafte Anwendung integriert, um deren praktische Anwendbarkeit zu verdeutlichen. Die vorliegende Arbeit zeigt, dass virtuelle Umgebungen auf realen Fähigkeiten und Erfahrungen aufbauen können, um eine vertraute und einfache Interaktion und Zusammenarbeit von Benutzern zu gewährleisten. Darüber hinaus ermöglichen individuelle Erweiterungen des virtuellen Inhalts und der Avatare Einschränkungen der realen Welt zu überwinden und das Erlebnis von VR-Umgebungen zu steigern

Performance Through an Avatar: Exploring Affect and Ideology Through Narrative in Videogames

Videogames are a major source of popular cultural narratives surpassing even Hollywood films. Videogames, however, cast the player as the active agent within the narrative as opposed to film, television, and traditional theatre where the separation between performer and audience is clearly demarcated. This dissertation investigates the affective potential of videogames realized through the relationship of the player and the avatar within the game world. Specifically, I look at the avatar as an affective conduit for the player, how the feedback between the player and avatar creates a cybernetic relationship, how this relationship changes the player, and how this change potentially augments the players interpretation of realityvirtual and otherwise. It is through this changed (and augmented) interpretation of reality that socio/political ideological meaningsintentional or notmay be absorbed by the player. Ethnographic research conducted with six volunteer participants combined with my own autoethnographic research into several recent popular videogames is intersected with theories of affect, embodiment, and ideology. My findings suggest that experience with the virtual realities of game worlds is one step removed from actual experience. Since videogames are composed of representations, the ideological positions embedded within those representations are not simply presented and understood like traditional theatre, film, and television, but are embodied by the player through the avatar as (nearly direct) experience. Theatre, film, and television have rich critical histories and this study of the players performance through the avatar as an affective conduit and receiver/transmitter of ideology joins the growing critical body of work regarding the newer storytelling medium of videogames

Value Co-Creation in Smart Services: A Functional Affordances Perspective on Smart Personal Assistants

In the realm of smart services, smart personal assistants (SPAs) have become a popular medium for value co-creation between service providers and users. The market success of SPAs is largely based on their innovative material properties, such as natural language user interfaces, machine learning-powered request handling and service provision, and anthropomorphism. In different combinations, these properties offer users entirely new ways to intuitively and interactively achieve their goals and thus co-create value with service providers. But how does the nature of the SPA shape value co-creation processes? In this paper, we look through a functional affordances lens to theorize about the effects of different types of SPAs (i.e., with different combinations of material properties) on users’ value co-creation processes. Specifically, we collected SPAs from research and practice by reviewing scientific literature and web resources, developed a taxonomy of SPAs’ material properties, and performed a cluster analysis to group SPAs of a similar nature. We then derived 2 general and 11 cluster-specific propositions on how different material properties of SPAs can yield different affordances for value co-creation. With our work, we point out that smart services require researchers and practitioners to fundamentally rethink value co-creation as well as revise affordances theory to address the dynamic nature of smart technology as a service counterpart
