In this age of DNA computers and artificial intelligence, information is becoming disembodied even as the "bodies" that once carried it vanish into virtuality. While some marvel at these changes, envisioning consciousness downloaded into a computer or humans "beamed" _Star Trek_-style, others view them with horror, seeing monsters brooding in the machines. In _How We Became Posthuman,_ N. Katherine Hayles separates hype from fact, investigating the fate of embodiment in an information age. Hayles relates three interwoven stories: how information lost (...) its body, that is, how it came to be conceptualized as an entity separate from the material forms that carry it; the cultural and technological construction of the cyborg; and the dismantling of the liberal humanist "subject" in cybernetic discourse, along with the emergence of the "posthuman." Ranging widely across the history of technology, cultural studies, and literary criticism, Hayles shows what had to be erased, forgotten, and elided to conceive of information as a disembodied entity. Thus she moves from the post-World War II Macy Conferences on cybernetics to the 1952 novel _Limbo_ by cybernetics aficionado Bernard Wolfe; from the concept of self-making to Philip K. Dick's literary explorations of hallucination and reality; and from artificial life to postmodern novels exploring the implications of seeing humans as cybernetic systems. Although becoming posthuman can be nightmarish, Hayles shows how it can also be liberating. From the birth of cybernetics to artificial life, _How We Became Posthuman_ provides an indispensable account of how we arrived in our virtual age, and of where we might go from here. (shrink)

Dans La structure du comportement Merleau-Ponty introduit le concept d' « espace virtuel », dans la Phénoménologie de la perception ceux de « mouvement virtuel » et de « corps virtuel ». L'objectif de cet article est d'établir les liens entre ces trois notions que Merleau-Ponty emprunte à la littérature psychologique de son temps et de montrer pourquoi elles constituent des éléments-clés de sa philosophie de la perception.

It is widely accepted that embodiment is crucial for any self-aware agent. What is less obvious is whether the body has to be real, or whether a virtual body will do. In that case the notion of embodiment would be so attenuated as to be almost indistinguishable from disembodiment. In this article I concentrate on the notion of embodiment in human agents. Could we be disembodied, having no real body, as brains-in-a-vat with only a virtual (...) body? Thought experiments alone will not suffice to answer this Cartesian question. I will draw on both philosophical arguments and empirical data on phantom phenomena. My argument will proceed in three steps. Firstly I will show that phantom phenomena provide a prima facie argument that real embodiment is not necessary for a human being. Secondly I will give a philosophical argument that real movement must precede the intention to move and to act. Agents must at least have had real bodies once. Empirical data seems to bear this out. Finally, however, I will show that a small number of aplasic phantom phenomena undermines this last argument. Most people must have had a real body. But for some people a partly virtual, unreal, phantom body seems to suffice. Yet though there is thus no knockdown argument that we could not be brains-in-a-vat, we still have good reasons to suppose that embodiment must be real, and not virtual. (shrink)

We previously showed that the illusory sense of ownership and agency over a moving body in immersive virtual reality can trigger subjective and physiological reactions on the real subject’s body and, therefore, an acute improvement of cognitive functions after a single session of high-intensity intermittent exercise performed exclusively by one’s own virtual body, similar to what happens when we actually do physical activity. As well as confirming previous results, here, we aimed at finding in the (...) elderly an increased improvement after a longer virtual training with similar characteristics. Forty-two healthy older subjects completed a parallel-group randomized controlled trial including an adapted version of the virtual training previously used: while sitting, participants observed the virtual body in a first-person perspective or a third-person perspective performing 20 min of virtual high-intensity intermittent exercise. This was repeated twice a week for 6 weeks. During the vHIE, we measured the heart rate and administered questionnaires to evaluate illusory body ownership and agency. Before the beginning of the intervention, immediately after the first session of vHIE, and at the end of the entire intervention, we evaluated the cognitive performance at the Stroop task with online recording of the hemodynamic activity over the left dorsolateral prefrontal cortex. While we confirm previous results regarding the virtual illusion and its physiological effects, we did not find significant cognitive or neural improvement immediately after the first vHIE session. As a novelty, in the 1PP group only, we detected a significant decrease in the response time of the Stroop task in the post-intervention assessment compared to its baseline; coherently, we found an increased activation on left dorsolateral prefrontal cortex after the entire intervention. While the current results strengthen the impact of the virtual full-body illusion and its physiological consequences on the elderly as well, they might have stronger and more established body representations. Perhaps, a longer and increased exposure to those illusions is necessary to initiate the cascade of events that culminates to an improved cognitive performance. (shrink)

Tomando o corpo como campo de possibilidades perante um cenário actual de desassossegos e desafios – corpo em processo de construção social e de virtualização –, aponta-se para a necessidade de uma sua revisão crítica, nomeadamente por parte da cultura de Design. Porque todos os objectos se relacionam sempre com o corpo, há que descobrir e considerar ligações. A compreensão dessas ligações e a consideração de uma contínua teorização do corpo serão certamente da maior utilidade para a prática de uma (...) disciplina que projecta constantemente com o corpo e para o corpo. Disciplina que deve cumprir, sempre, uma função ética reguladora: social, cultural, ecológica, humana. (shrink)

Manipulating sensory and motor cues can cause an illusionary perception of ownership of a fake body part. Presumably, the illusion can work as long as the false body part’s position and appearance are anatomically plausible. Here, we introduce an illusion that challenges past assumptions on body ownership. We used virtual reality to switch and mirror participants’ views of their hands. When a participant moves their physical hand, they see the incongruent virtual hand moving. The result (...) is an anatomically implausible configuration of the fake hand. Despite the hand switch, participants reported significant body ownership sensations over the virtual hands. In the first between-group experiment, we found that the strength of body ownership over the incongruent hands was similar to that of congruent hands. Whereas, in the second within-group experiment, anatomical incongruency significantly decreased body ownership. Still, participants reported significant body ownership sensations of the switched hands. Curiously, we found that perceived levels of agency mediate the effect of anatomical congruency on body ownership. These findings offer a fresh perspective on the relationship between anatomical plausibility and assumed body ownership. We propose that goal-directed and purposeful actions can override anatomical plausibility constraints and discuss this in the context of the immersive properties of virtual reality. (shrink)

As screen-based virtual worlds have gradually begun facilitating more and more of our social interactions, some researchers have argued that the virtual worlds of these interactions do not allow for embodied social understanding. The aim of this article is to examine exactly the possibility of this by looking to esports practitioners’ experiences of interacting with each other during performance. By engaging in an integration of qualitative research methodologies and phenomenology, we investigate the actual first-person experiences of interaction in (...) the virtual worlds of the popular team-based esports practices Counter Strike: Global Offensive and League of Legends. Our analysis discloses how the practitioners’ interactions essentially depend on intercorporeality – understood as a form of reciprocity of bodily intentionality between the players. This is an intercorporeality that is present throughout the players’ performance, but which especially comes to the front when they engage in feinting. Acknowledging the intercorporeality integral to at least some esports practices helps fuzzying the sharp division between virtuality and embodied social understanding. Doing so highlights the fluidity of our embodied condition, and it raises interesting questions concerning the possibility of yet other forms of embodied sociality in a wider range of virtual formats in the world.

ABSTRACT The current article deals with the correlation between virtual and physical reality as they concern the body. The thesis of this article is that the lived body transposed into virtual reality becomes a body without organs in Deleuze’s terms, i.e. the lived body, a sensitive field of sensorial events immersed in a lived space, becomes a virtual body made up of intensities, of pure forces or magnitudes within a vector space, thereby (...) losing its affective qualities. Furthermore, lived and virtual bodies build up a correlation bridged not by intentionality, as phenomenology would maintain, but by sensation. Virtuality is thus characterised by both the loss of corporeality and the simulation of the lifeworld. But how can the split between the real and the virtual body be bridged? On the one hand, in Deleuze’s conception of sensation, real and virtual collapse into one another so that the real world ‘resonates’ with its virtual double. On the other hand, Merleau-Ponty’s concept of form relates both realities in terms of a correlation of signification between the physical and the existential realms. With recourse to the notion of structure or form, I will argue that the phenomenal and the virtual do not represent different modes of being, but are bound by a correlation ruled by sensation as a system of intensive forces.

While many scholars have decried the erasure of the body in virtual reality (VR), this paper focuses on the body – and the physical reality for which it stands – as a critical component of any experience of virtual reality. Specifically, studying VR from the perspective of the physical body allows for a more nuanced appreciation of the unique reality of this «virtual» reality. Moreover, this paper argues that the body should not be (...) seen as a distraction from the immersive potential of VR, but rather as a potential tool for augmenting what virtual reality can currently offer.

Body, Soul and Cyberspace explores how recent science-fiction cinema addresses questions about the connections between body and soul, virtuality, and the ways in which we engage with spirituality in the digital age. The book investigates notions of love, life and death, taking an interdisciplinary approach by combining cinematic themes with religious, philosophical and ethical ideas. Magerstädt argues how even the most spectacle-driven mainstream films such as Avatar, The Matrix and Terminator can raise interesting and important questions about the (...) human self and our interaction with the world. Apart from these well-known science fiction epics, her analysis also draws on recent works, such as Inception, The Thirteenth Floor, eXistenZ, Aeon Flux, Total Recall (2012), Transcendence and TRON: Legacy. These films stimulate an engaging discussion on what makes us human, the role memory plays in understanding ourselves, and how virtual realities challenge the moral concepts that govern human relationships.

Anorexia nervosa patients exhibit distorted body-representations. Specifically, they represent their bodies as larger than reality. Given that this distortion likely exacerbates the condition, there is an obligation to further understand and, if possible, rectify it. In pursuit of this, experimental paradigms are needed which manipulate the spatial content of these representations. In this essay, I discuss how virtual reality technology that implements full-body variants of the rubber-hand illusion may prove useful in this regard, and I discuss some (...) issues related to the clinical application of this method. -/- .

This paper analyzes in the use of virtual reality when used to induce full-body ownership in violent offenders in order to elicit empathetic feelings by allowing them to embody the virtual body of a victim of domestic abuse. The authors explore potentially harmful effects to individuals participating in this kind of therapy and question whether consent is fully informed. The paper concludes with guidelines for ethical research and rehabilitation using this innovative technology.

When your word processor or email program is running on your computer, this creates a “virtual machine” that manipulates windows, files, text, etc. What is this virtual machine, and what are the virtual objects it manipulates?

T h i s article examines the ethical implications of the desirefor disembodiment situated in the texts and technologies of cyberspace. The article is divided into 2 parts. The first traces the conceptual history of dualism, demonstrating its exclusive cultural politics and investigating the socio-political consequences of encoding this metaphysical information in contemporary media technology. The second part examines the material conditions of new communication technology, arguing that the issue of access reduplicates in practice the exclusivity of dualism. The article (...) concludes by investigating the ethical implications of employing dualistic metaphysics as a legitimizing narrative of media technology and cyberculture. (shrink)

ABSTRACT Like no other medium, virtual reality (VR) offers new possibilities to alter the perception of reality. These possibilities are mainly related to the feeling of presence in a virtual environment. With the VR performance ‘The Machine to be Another’ (TMTBA), we find an innovative embodiment system that enables a virtual body swap between two users. Hence, we conceptualise the performance as some kind of breaching experiment in order to alter self- and body perception. With (...) the use of TMTBA and a qualitative research approach, we hope to gain a closer insight into the formation, alteration and persistence of body images. This challenges the phenomenological idea that our sense of bodily presence is essentially anchored in our physical or ‘objective’ body as we know it and seems to potentially expand our notion of what bodily presence can mean.

This paper is going to discuss, what will be called, ‘The Internet of Bodies’. Our physical and virtual worlds are blending and shifting our understanding of three key areas: (1) our identities are diversifying, as they become hyper-enhanced and multi-sensory; (2) our collaborations are co-created, immersive and connected; (3) our innovations are diverse and inclusive. It is proposed that our bodies have finally become the interface.

In the last decades videogames have become very popular. In this article I argue that they establish a new relationship between bodies and identities. In videogames, the storylines are based on a mixture of other types of media fiction, where women's bodies are overrepresented and stereotypical, because of the market logic underlying these new media productions, which target a wide audience. Nevertheless, videogames' interactivity shapes new experiences of acting through other bodies. The erotic gaze on virtual bodies is shaped (...) by the elements of exoticism and the grotesque. The virtual spaces and actions are characterized by exoticism (the recurrent presence of death, fear, surprise, thrills) and the realism necessary to involve the user's senses. I also argue that interaction in games is a process of imagination and action. The game user acts through another body, which he/she controls. This process opens possibilities for a resisting oppositional gaze and subversive practices, beyond the commercial aims of the games' designers. Of course, there are oppressive aspects of the virtual bodies; a female body becomes a mathematical series of polygons, out of space and time, and, only as such, the object of desire of invisible cyberteenagers. Nevertheless, as gendered subjects, to have a virtual body to play with is a liberating appropriation of a space not designed for us. (shrink)

The persisting usage of virtual means for the completion of activities usually or traditionally held in person stimulates the reflection about the possible effect that doing philosophy online could have on the philosophical integrity of the process. The body question seems to be pivotal in this context not only as far as concerning virtuality issues but also philosophy’s care to integrate the body into its routines – when it is practiced physically – especially in the frame of (...) an education still hesitating to embrace embodied experience. The body deficiency, its vanishing, is first of all a question for philosophy and its ways to be practiced today – on that basis, passing through virtuality’s discourses can enlighten the relevant reflection.

"New technologies implied in art creation and exhibition are modifying the traditional landmarks on which aesthetics has always focused. In particular, Virtual Reality artworks call the body into question when it comes to living a bodily experience within exhibitions accessible through technological tools that expand the human body’s capabilities and motor potential. The body's status is challenged in its traditional unity, that of a subject of experience living in a world where the spatial configuration is relatively (...) constant. Conversely, in Virtual Reality, the spatial aspect is novel to our body which needs to adapt to unpredicted and disorientating motor schemas. Therefore, the Virtual Reality aesthetic experience takes place into a novel configuration for the human body: hybrid and split into the virtual realm.

This paper analyzes the transformations in anatomical representation introduced by the Visible Human Project, the first complete virtual anatomy object. By comparing the process of production of book based classical anatomy with that of the Visible Human Project, the paper identifies the medium specificity of anatomical knowledge, the extent to which its powers of demonstration and analysis are conditioned by the medium in which they take place. The paper argues that anatomy can be productively thought of as a kind (...) of writing practice, in which material flesh is written into different media as traces. Because the production of such traces always involves the destruction of the body involved the paper also interrogates the biopolitical hierarchies involved in anatomical knowledge. (shrink)

The journey into the world of midwifery or nursing requires the student to attend to the intertwining of self-body-world in order to shift their knowledge of self-body-world into a client/patient-centered context. One of the teaching-learning strategies used to provide safe opportunities is the use of simulations and virtual practices. Rather than learning intimate acts of touching, or life and death decision-making in situations with actual clients/patients, students enter their learning world with rubber torsos, cloth babies, and cyber (...) clinics. The “other” is a simulated other, not a human. How does the student shift from seeing this simulated other as object to a sense of other as subject? In our world of constant use of technology for communication and entertainment, do students shift in and out of a cyber world easily or are they more captured by the simulated experience than with the human world? Has the human world redefined itself where the intertwining of self-body-world blurs the sense of where human body ends and cyber or simulated world begins? What is the place of Bildung when engaged with a cyber other? As a result of educational challenges, including rising enrolments, limited clinical placement opportunities, and increasing risk management concerns, there has been a proliferation in the use of simulation as a teaching strategy. This has left us –the authors– wondering about the student experience of simulation. What do they learn? How do they learn? How can this learning be applied in practice? (shrink)

The author of this paper discusses the theme of the "simulated body", that is the sense of "being there” in a body that is not one's own, or that does not exist in the way one perceives it. He addresses this issue by comparing Immersive Virtual Reality technology, the phenomenological approach, and Gerald Edelman's theory of Neural Darwinism. Virtual Reality has been used to throw light on some phenomena that cannot be studied experimentally in real life, (...) and the results of its simulations enrich the phenomenological discourse on the lived body. Virtual “Reality” seems to replicate—at least in part—the simulation mechanisms of our mind, thus favoring developments in the field of philosophy of mind. (shrink)

The quadruped robot is subject to self and external interference during the running process. In this paper, in order to improve the stability of the quadruped robot, a disturbance suppression strategy based on the kinematic model and the virtual model is proposed. Through the whole-body kinematics modeling of the body, the cause of the disturbance is analyzed. At the same time, two spring-damping virtual elements are introduced on the body. The virtual force generated by (...) the spring-damping model is according to the displacement and speed of the CoM when the robot is moving. By simulating the tort gait of the robot, sorting out the data obtained from the experiment, and drawing a comparison curve with the experiment results of the no spring-damping virtual element under the same conditions, it is proved that the method proposed in this paper has a significant effect on maintaining the dynamic stability of the body, and the actual trajectory is not different from the theoretical trajectory.

Is it possible to say that there is no real self if we take a non-Cartesian view of the body? Is it possible to say that an organism can engage in pragmatic action and intersubjective interaction and that the self generated in such activity is not real? This depends on how we define the concept "real". By taking a close look at embodied action, and at Metzinger's concept of embodiment, I want to argue that, on a non-Cartesian concept of (...) reality, the self should be considered something real, and not simply an illusion.

The Virtual Embodied is intended to inform and provoke. It juxtaposes cutting-edge theories, polemics, and creative practices to uncover ethical, aesthetic and ecological implications of why, how and in particular where, human actions, observations and insights take place. It refuses simply to hold a euphoric view of technology yet equally resists the apocalyptic scorn which surrounds the new. The contributors use a range of interdisciplinary strategies to point to a re-worked aesthetic for embodying knowledge and explore such areas as (...) colonialism and the internet, the virtual unconscious in electronic systems, theatre as a virtual space, 'information' and the capitalist society, ecstatic bodies and the rave scene, desire and the 'virtual comfort' zone. In The Virtual Embodied many of the authors, artists, performers and designers apply their interdisciplinary passions to questions of embodied knowledge and virtual space. (shrink)
