This dissertation aims to position train surfing as a visual spectacle that is practised by Sowetan train surfers within the context of post-authoritarian Johannesburg. The author argues that train surfing is a visual and spatial phenomenon that is theoretically under-researched. As such, this study aims to decode seven train surfing videos to establish what train surfing looks like, where train surfing occurs and why individuals participate in such a high risk activity. This study, furthermore, aims to frame train surfing as a spectacle by investigating the similarities between train surfing and rites of passage (initiation rites). The author also regards train surfing as a very specific form of storytelling. The narratives conveyed in the seven videos are, therefore, interpreted to establish that train surfing is practised to ‘voice’ fatalistic feelings, societal as well as individual crises. After establishing the visual aspects of train surfing, the author focuses on the spatial context of train surfing. Johannesburg is described as both an authoritarian and post-authoritarian construct by tracing the spatial and political history of the city. When the discussion turns to the post-authoritarian city, townships and squatter settlements are analysed as being both marginal and hybrid spaces. It is argued that townships are marginal spaces due to their location, they are inhabited by the underclass and they are formed by processes of capitalism and urbanisation, and as a result of these factors, township residents might have fatalistic mindsets (Gulick 1989). The author, however, contends that township space is an ambivalent construct, and as such, it can also be read as hybrid space. Here, hybrid space is interpreted as a platform from which township residents can resist oppressing spatial and political ideologies. In this context, train surfing is regarded as one way in which train surfers use hybrid space to express tactics of resistance. After establishing the spatial context of train surfing, the socio-economic and material living conditions of train surfers are investigated. The discussion firstly, explores the underclass, as theorised by Jencks and Peterson (1990), and thereafter highlights why train surfers can be classified as being part of this sub-category. It is, furthermore, argued that Sowetan train surfers are part of a new lost generation due to high unemployment rates, the HIV/AIDS pandemic and bleak future outlooks. The author aims to establish that, as a result of their socio-economic status and material living conditions, train surfers are fatalistic, and practice an extreme activity to exert control over one area of their lives, namely their bodies. Lastly, the dissertation aims to explore train surfing as being both a risk-taking activity and a new spatial practice. The dynamics of adolescent risk-taking behaviour is explored by emphasising the psychological motivations behind high risk activities. The author argues that alienating space can be regarded as an additional factor that usher adolescents into risk-taking activities. As such, the place(s) and space(s) inhabited by train surfers, namely Johannesburg, Soweto and township train stations, are discussed as alienating spaces. Moreover, it is argued that alienating spaces create opportunities for resistance (following the power-resistance dialectic inherent to space), and as such, train surfing is interpreted as a de-alienating spatial practice that enables the marginalised train surfer to exert control over his surroundings. / Dissertation (MA)--University of Pretoria, 2012. / Visual Arts / unrestricted

This thesis is a contribution to design-led research and addresses a readership in the fields of architecture as well as in media and communications. In juxtaposing the tools of the designer (e.g. drafting, prototyping, visual/textual/spatial forms of montage) with those of architectural theory, this thesis seeks to extend the disciplinary boundaries of architecture by observing its assimilation of other media practices. Its primary contribution is to architectural design and theory, and its aims are twofold: Firstly, this thesis applies the concepts of virtual and mediated space to architecture, proposing an extended architectural practice that assimilates the concept of remote presence. Through realized design examples as well as through the history and theory of related concepts, the thesis explores what designing mediated spaces and designing for presence entails for the practicing architect. As a fusion of architecture and media technology, video-mediated spaces facilitate collaborative practices across spatial extensions while simultaneously fostering novel and environmentally sustainable modes of communication. The impact of presence design on workplace design is examined. As an extended practice also calls for an extended discourse, a preliminary conceptual toolbox is proposed. Concepts are adapted from related visual practices and tested on design prototypes, which arise from the author’s extensive experience in designing work and learning spaces. Secondly, this thesis outlines presence design as a transdisciplinary aesthetic practice and discusses the potential contribution of architects to a currently heterogeneous research field, which spans media space research, cognitive science, (tele)presence research, interaction design, ubiquitous computing, second-order cybernetics, and computer-supported collaborative work. In spite of such diversity, design and artistic practices are insufficiently represented in the field. This thesis argues that presence research and its discourse is characterised by sharp disciplinary boundaries and thereby identifies a conceptual gap: presence research typically fails to integrate aesthetic concepts that can be drawn from architecture and related visual practices. It is an important purpose of this thesis to synthesize such concepts into a coherent discourse. Finally, the thesis argues that remote presence through the proposed synthesis of architectural and technical design creates a significantly expanded potential for knowledge sharing across time and space, with potential to expand the practice and theory of architecture itself. The author’s design-led research shows that mediated spaces can provide sufficient audiovisual information about the remote space(s) and other person(s), allowing the subtleties of nonverbal communication to inform the interaction. Further, in designing for presence, certain spatial features have an effect on the user’s ability to experience a mediated spatial extension, which in turn, facilitates mediated presence. These spatial features play an important role in the process through which trust is negotiated, and hence has an impact on knowledge sharing. Mediated presence cannot be ensured by design, but by acknowledging the role of spatial design in mediated spaces, the presence designer can monitor and, in effect, seek to reduce the ‘friction’ that otherwise may inhibit the experience of mediated presence. The notion of ‘friction’ is borrowed from a context of knowledge sharing in collaborative work practices. My expanded use of the term ‘design friction’ is used to identify spatial design features which, unaddressed, may be said to impose friction and thus inhibit and impact negatively on the experience of presence. A conceptual tool-box for presence design is proposed, consisting of the following design concepts: mediated gaze, spatial montage, active spectatorship, mutual gaze, shared mediated space, offscreen space, lateral and peripheral awareness, framing and transparency. With their origins in related visual practices these emerge from the evolution of the concept of presence across a range of visual cultures, illuminating the centrality of presence design in design practice, be it in the construction of virtual pictorial space in Renaissance art or the generative design experiments of prototypical presence designers, such as Cedric Price, Gordon Pask and numerous researchers at MIT Media Lab, Stanford Institute and Xerox PARC. / QC 20100909
