    What does not happen: quantifying embodied engagement using NIMI and self-adaptors

    Previous research into the quantification of embodied intellectual and emotional engagement using non-verbal movement parameters has not yielded consistent results across different studies. Our research introduces NIMI (Non-Instrumental Movement Inhibition) as an alternative parameter. We propose that the absence of certain types of possible movements can be a more holistic proxy for cognitive engagement with media (in seated persons) than searching for the presence of other movements. Rather than analyzing total movement as an indicator of engagement, our research team distinguishes between instrumental movements (i.e. physical movement serving a direct purpose in the given situation) and non-instrumental movements, and investigates them in the context of the narrative rhythm of the stimulus. We demonstrate that NIMI occurs by showing viewers’ movement levels entrained (i.e. synchronised) to the repeating narrative rhythm of a timed computer-presented quiz. Finally, we discuss the role of objective metrics of engagement in future context-aware analysis of human behaviour in audience research, interactive media and responsive system and interface design

    What\u27s in a Name? The Matrix as an Introduction to Mathematics

    In my classes on the nature of scientific thought, I have often used the movie The Matrix (1999) to illustrate how evidence shapes the reality we perceive (or think we perceive). As a mathematician and self-confessed science fiction fan, I usually field questions related to the movie whenever the subject of linear algebra arises, since this field is the study of matrices and their properties. So it is natural to ask, why does the movie title reference a mathematical object? Of course, there are many possible explanations for this, each of which probably contributed a little to the naming decision. First off, it sounds cool and mysterious. That much is clear, and it may be that this reason is the most heavily weighted of them all. However, a quick look at the definitions of the word reveals deeper possibilities for the meaning of the movie’s title. Consider the following definitions related to different fields of study taken from Wikipedia on January 4, 2010: • Matrix (mathematics), a mathematical object generally represented as an array of numbers. • Matrix (biology), with numerous meanings, often referring to a biological material where specialized structures are formed or embedded. • Matrix (archeology), the soil or sediment surrounding a dig site. • Matrix (geology), the fine grains between larger grains in igneous or sedimentary rocks. • Matrix (chemistry), a continuous solid phase in which particles (atoms, molecules, ions, etc.) are embedded. All of these point to an essential commonality: a matrix is an underlying structure in which other objects are embedded. This is to be expected, I suppose, given that the word is derived from the Latin word referring to the womb — something in which all of us are embedded at the beginning of our existence. And so mathematicians, being the Latin scholars we are, have adapted the term: a mathematical matrix has quantities (usually numbers, but they could be almost anything) embedded in it. A biological matrix has cell components embedded in it. A geological matrix has grains of rock embedded in it. And so on. So a second reason for the cool name is that we are talking, in the movie, about a computer system generating a virtual reality in which human beings are embedded (literally, since they are lying down in pods). Thus, the computer program forms a literal matrix, one that bears an intentional likeness to a womb. However, there are other ways to connect the idea of a matrix to the film’s premise. These explanations operate on a higher level and are explicitly relevant to the mathematical definition of a matrix as well as to the events in the trilogy of Matrix movies. They are related to computer graphics, Markov chains, and network theory. This essay will explore each of these in turn, and discuss their application to either the events in the film’s story-line or to the making of the movie itself

    In this article, I explore, with you, artists’ socio-political disruptions with communication technologies to inspire political action and social change, and how such art can be environmentally and socially useful. How does art function politically? What is activist art? What non-violent forms of dissent or disruptions to harmful practices are possible today with digital technologies, and how do artists manifest political perspectives in their practice

    Holograms: The story of a word and its cultural uses

    Get PDF
    Holograms reached popular consciousness during the 1960s and have since left audiences alternately fascinated, bemused or inspired. Their impact was conditioned by earlier cultural associations and successive reimaginings by wider publics. Attaining peak public visibility during the 1980s, holograms have been found more in our pockets (as identity documents) and in our minds (as video-gaming fantasies and “faux hologram” performers) than in front of our eyes. The most enduring, popular interpretations of the word “hologram” evoke the traditional allure of magic and galvanize hopeful technological dreams. This article explores the mutating cultural uses of the term “hologram” as marker of magic, modernity and optimism

    E-topia: Utopia after the Mediated Body

    Get PDF
    open access journalA custom-made media installation, diplorasis, will be used to explore the body in digital media. This mediated body attempts to re-think how the Deleuzian time-image is translated from its cinematic confinement to the space of new media. In diplorasis the digitized time-image becomes more directly incorporated with-in the bodily schema. Consequently, the thinking of the virtual and actual space of the body in diplorasis enables a questioning of bodily space-time, and particularly the relation between self and digitized self-image. It is thus crucial to re-frame how this digitized mediated body is distinct from a conventional notion of a metric and habitual space—one that is reinforced by, for example, the medium of linear perspective. The articulation of the mediated body will be used to in-form and extend Elizabeth Grosz’s paradoxical reading of embodiment and utopia, by revisiting the notions of utopia as eu-topic/ou-topic. The spatio-temporality of the topos must be re-considered before utopia. Foucault’s analogy of the mirror will then serve to superimpose the dual and slippery relations between utopia and the heterotopic. The digitized mediated body will thus seek to explore emerging ways by which to consider the utopic by conflating embodiment, time and space within an electronic topos. It is argued that as the sensing and cognitive body becomes increasingly pliable in relation to technological mediations, our very understanding of space-time is changing

    Creativity: from discourse to doctrine

    Get PDF
    This is a short report on work in progress. It centres on the idea of ‘creativity’, which is of presently of key importance for current UK government thinking about the ‘creative economy’. ‘Creativity’, I shall argue, has established itself as a hegemonic term in an increasingly elaborated framework of policy ideas. Although my focus is on the UK, we are addressing a body of thought that is now increasingly international in scope. The ideas in question are influential and set the terms for thought and action across a number of policy fields. Not for nothing has David Puttnam, a key ‘New’ Labour figure, said that ‘the importance of the creative industries was quickly enshrined as an article of faith’. An analysis of New Labour discourse reveals an underlying credo – itself a fit subject for the critique of ideology. A concerted effort is under way to shape a wide range of working practices by invoking creativity and innovation. These attributes are supposed to make our societies and economies grow in a fiercely competitive world. At present, official thinking circulates in a dominant culture of largely uncritical acceptance. Alongside the elaboration of the doctrine of creativity by the government policy apparatus is a specialist discourse of academic analysis. If it is now fashionable to see the creative economy as pivotal to the wider economy, this view is certainly not limited to policy makers. As creativity has moved centre stage, it has also become extraordinarily banal. The mark of its present hegemony is that it is also increasingly ubiquitous. ‘British creativity’, for instance, ensures market success for Thornton’s, the chocolate manufacturers, so their advertising tells us. Not on its own, to be sure: cocoa and sugar are added ingredients. In a district nearby to mine in Glasgow, there is a ‘creative hairdresser’. We who stay without must ponder what wondrous transformations occur under the stylists’ hands. My inbox is regularly assaulted by spam offering courses to explore my creativity (and temptingly, to develop my ludic qualities) in New York City and various European locations. So far I have managed to resist. Such examples could easily be multiplied

    This paper presents the calculation of the perceived color of dielectric films on silicon. A procedure is shown for computing the perceived color for an arbitrary light source, light incident angle, and film thickness. The calculated color is converted into RGB parameters that can be displayed on a color monitor, resulting in the generation of electronic color charts for dielectric films. This paper shows generated electronic color charts for both silicon dioxide and silicon nitride films on silicon
