In order to take advantage of the potential offered by the medium of virtual reality, it will be essential to develop an understanding of how to maximize the desirable experience of ‘presence’ in a virtual space (‘being there’), and how to minimize the undesirable feeling of ‘cybersickness’ (a constellation of discomfort symptoms experienced in virtual reality). Although there have been frequent reports of a possible link between the observer’s sense of presence and the experience of (...) bodily discomfort in virtual reality, the amount of literature that discusses the nature of the relationship is limited. Recent research has underlined the possibility that these variables have shared causes, and that both factors may be manipulated with a single approach. This review paper summarizes the concepts of presence and cybersickness and highlights the strengths and gaps in our understanding about their relationship. We review studies that have measured the association between presence and cybersickness, and conclude that the balance of evidence favours a negative relationship between the two factors which is driven principally by sensory integration processes. We also discuss how system immersiveness might play a role in modulating both presence and cybersickness. However, we identify a serious absence of high-powered studies that aim to reveal the nature of this relationship. Based on this evidence we propose recommendations for future studies investigating presence, cybersickness, and other related factors. (shrink)

The use of head-mounted displays (HMD) for virtual reality (VR) application-based purposes including therapy, rehabilitation, and training is increasing. Despite advancements in VR technologies, many users still experience sickness symptoms. VR sickness may be influenced by technological differences within HMDs such as resolution and refresh rate, however, VR content also plays a significant role. The primary objective of this systematic review and meta-analysis was to examine the literature on HMDs that report Simulator Sickness Questionnaire (SSQ) scores to (...) determine the impact of content. User factors associated with VR sickness were also examined. A systematic search was conducted according to PRISMA guidelines. Fifty-five articles met inclusion criteria, representing 3,016 participants (mean age range 19.5-80; 41% female). Findings show gaming content recorded the highest total SSQ mean 34.26 (95%CI 29.57-38.95). VR sickness profiles were also influenced by visual stimulation, locomotion and exposure times. Older samples (mean age ≥35 years) scored significantly lower total SSQ means than younger samples, however, these findings are based on a small evidence base as a limited number of studies included older users. No sex differences were found. Across all types of content, the pooled total SSQ mean was relatively high 28.00 (95%CI 24.66-31.35) compared with recommended SSQ cut-off scores. These findings are of relevance for informing future research and the application of VR in different contexts. (shrink)

This article looks through a critical media lens at mediated effects and ethical concerns of virtual reality applications that explore personal and social issues through embodiment and storytelling. In recent years, the press, immersive media practitioners and researchers have promoted the potential of virtual reality storytelling to foster empathy. This research offers an interdisciplinary narrative review, with an evidence-based approach to challenge the assumptions that VR films elicit empathy in the participant—what I refer to as the (...) VR-empathy model. A review of literature from the fields of psychology, computer science, embodiment, medicine, and virtual reality was carried out to question and counter these claims through case studies of both fiction and non-fiction VR experiences. The results reveal that there is little empirical evidence of a correlation between VR exposure and an increase in empathy that motivates pro-social behavior, and a lack of research covering VR films exposure eliciting empathy. Furthermore, the results show an alarming lack of research into the long-term effects of VR films and other VR immersive experiences. This contribution aims to understand and demystify the current “empathy machine” rhetoric and calls for more rigorous, scientific research that can authenticate future claims and systemize ethical best practices.

Recent improvements in virtual reality allow for the representation of authentic environments and multiple users in a shared complex virtual world in real time. These advances have fostered clinical applications including in psychiatry. However, although VR is already used in clinical settings to help people with mental disorders, the related ethical issues require greater attention. Based on a thematic literature search the authors identified five themes that raise ethical concerns related to the clinical use of VR: (...) reality and its representation, autonomy, privacy, self-diagnosis and self-treatment, and expectation bias. Reality and its representation is a theme that lies at the heart of VR, but is also of specific significance in a clinical context when perceptions of reality are concerned, for example, during psychosis. Closely associated is the autonomy of VR users. Although autonomy is a much-considered topic in biomedical ethics, it has not been sufficiently discussed when it comes to applications of VR in psychiatry. In this review, the authors address the different themes and recommend the development of an ethical framework for the clinical use of VR. (shrink)

Immersive virtual reality (VR) emerges as a promising research and clinical tool. However, several studies suggest that VR induced adverse symptoms and effects (VRISE) may undermine the health and safety standards, and the reliability of the scientific results. In the current literature review, the technical reasons for the adverse symptomatology are investigated to provide suggestions and technological knowledge for the implementation of VR head-mounted display (HMD) systems in cognitive neuroscience. The technological systematic literature indicated features pertinent (...) to display, sound, motion tracking, navigation, ergonomic interactions, user experience, and computer’s hardware that should be considered by the researchers. Subsequently, a meta-analysis of 44 neuroscientific or neuropsychological studies involving VR HMD systems was performed. The meta-analysis of the VR studies demonstrated that the new generation HMDs induced significantly fewer dropouts and VRISE. Importantly, the commercial versions of the new generation HMDs with ergonomic interactions had zero incidents of adverse symptomatology and dropouts. Solely, HMDs equivalent to or greater than the commercial versions of contemporary HMDs accompanied with ergonomic interactions are suitable for implementation in cognitive neuroscience. In conclusion, researchers’ technological competency, along with meticulous methods and reports pertinent to software, hardware, and VRISE, are paramount to ensure the health and safety standards and the reliability of neuroscientific results.

Virtual reality constitutes an alternative, effective, and increasingly utilized treatment option for people suffering from psychiatric and neurological illnesses. However, the currently available VR simulations provide a predetermined simulative framework that does not take into account the unique personality traits of each individual; this could result in inaccurate, extreme, or unpredictable responses driven by patients who may be overly exposed and in an abrupt manner to the predetermined stimuli, or result in indifferent, almost non-existing, reactions when the stimuli (...) do not affect the patients adequately and thus stronger stimuli are recommended. In this study, we present a VR system that can recognize the individual differences and readjust the VR scenarios during the simulation according to the treatment aims. To investigate and present this dynamically adaptive VR system we employ an Anxiety Disorder condition as a case study, namely arachnophobia. This system consists of distinct anxiety states, aiming to dynamically modify the VR environment in such a way that it can keep the individual within a controlled, and appropriate for the therapy needs, anxiety state, which will be called “desired states” for the study. This happens by adjusting the VR stimulus, in real-time, according to the electrophysiological responses of each individual. These electrophysiological responses are collected by an external electrodermal activity biosensor that serves as a tracker of physiological changes. Thirty-six diagnosed arachnophobic individuals participated in a one-session trial. Participants were divided into two groups, the Experimental Group which was exposed to the proposed real-time adaptive virtual simulation, and the Control Group which was exposed to a pre-recorded static virtual simulation as proposed in the literature. These results demonstrate the proposed system’s ability to continuously construct an updated and adapted virtual environment that keeps the users within the appropriately chosen state for approximately twice the time compared to the pre-recorded static virtual simulation. Thus, such a system can increase the efficiency of VR stimulations for the treatment of central nervous system dysfunctions, as it provides numerically more controlled sessions without unexpected variations.

The article provides an analysis of one problem related to the discussion of the ontologi­cal status of virtual reality. The author proposes to discuss the problem of the reality of virtual worlds in terms of transformed forms. In this regard, an analysis is given of how this concept was introduced by K. Marx and how it was discussed further in the scientific literature. It is proposed to perceive the transformed form not as a perverted or (...) false real­ity, but as a separate form of life presented in its transformation. An example is the meta­morphosis of the cost of labor into the monetary form of a commodity, as was shown in Capital. On this example, a proposal is made, according to which virtual reality is the same transformed form of reality, and not an illusion of consciousness, and not an imaginary world. The qualities of the transformed form of reality are introduced: 1) a separate, but not independent form of life; 2) playing a role in the process of trans­formation as an indirect form; 3) representation in the form of a copy of the original; 4) sign-symbolic mode of existence; 5) dependence on the original, generic form of real­ity, not independence. It is shown that virtual reality is, as it were, an unembodied form of reality, existence in its potency. Such a representation was presented in the history of philosophy in the form of the idea of potential being. But this idea did not subse­quently become the basis for the development of an independent ontology of virtual real­ity. A distinction is made between the concept of virtual reality as a reality, not an illusion (the reality of digital objects) in the concept of D. Chalmers, and reality in the form of its transformed form. It is shown that virtual reality is not reduced only to the reality of imaginary worlds, to the reality of consciousness, the reality of special psychological states. The rationale is given that virtual reality is the continuation of a natural-artificial process of metamorphosis of human activity, only embodied in its transformed form. In this regard, the author proposes to interpret virtual reality as a form of life in its trans­formation and non-incarnation, which a person must use as a new resource for their de­velopment in order to overcome alienation from themselves.

An emerging line of research in bioethics questions whether enhanced love is less significant or valuable than otherwise, where "enhanced love" generally refers to cases where drugs (e.g., oxytocin, etc.) are relied on to maintain romantic relationships. Separate from these debates is a recent body of literature on the philosophy and psychology of "Virtual Reality (VR) dating," where romantic relationships are developed and sustained in a way that is mediated by VR. Interestingly, these discussions have proceeded largely (...) independently from each other. This article considers whether and to what extent philosophical arguments leveled against the value of enhanced love in the pharmacological case extend to cases where loving relationships are technologically mediated via VR rather than pharmacologically mediated. It will be argued that, while some worries about the pharmacological case do not extend over in a way that will be particularly problematic for VR, two (of the four arguments considered) are more prima facie serious. I conclude by suggesting why even these stronger argument strategies are not insurmountable and, thus, that there is reason to be cautiously optimistic that VR-mediated love can largely withstand variations on the bioconservative critiques that target pharmacologically enhanced love.

Virtual Reality has often been referred to as an “empathy machine.” This is mostly because it can induce empathy through embodiment experiences in outgroup membership. However, the potential of intergroup contact with an outgroup avatar in VR to increase empathy is less studied. Even though intergroup contact literature suggests that less threatening and more prosocial emotions are the key to understanding why intergroup contact is a powerful mean to decrease prejudice, few studies have investigated the effect of (...) intergroup contact on empathy in VR. In this study, we developed a between-participants design to investigate how VR can be used to create a positive intergroup contact with a member of a stigmatized outgroup and present the results of the effect of intergroup contact in VR on empathy. Sixty four participants experienced either positive contact with a black avatar or no intergroup contact, with situational empathy being measured through a self-report questionnaire up to a week before and right after the VR contact experience. The experiment showed that satisfying degrees of body ownership of participants’ own avatar and co-presence with the contacted avatar can be achieved in simple and universally accessible virtual environments such as AltspaceVR. The results indicated that while VR intergroup contact had no significant direct effect on empathy, exploratory analyses indicated that post-intervention empathic interest increased with stronger feelings of co-presence in the intergroup contact condition.

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)

This study investigates the Proteus effect from the first-person perspective and during avatar embodiment in actual exercise. In addition to the immediate measurements of the Proteus effect, prolonged effects such as next-day perception and exercise-related outcomes are also explored. We theorized the Proteus effect as altered perceived self-concept and explored the association between virtual reality avatar manipulation and self-concept in the exercise context. While existing studies have mainly investigated the Proteus effect in a non-VR environment or after VR (...) embodiment, we aim to contribute to the literature by addressing this concern to explore how the Proteus effect works in actual VR exercise. Through a 2 × 2 between-subject experiment, the results partially support the Proteus effect. Regarding actual physical activity, embodying an avatar with a six pack during exercise creates fewer body movements. No significant effect was found for perceived exertion. We also explored the role of sex as a potential moderator in the association of the Proteus effect on exercise outcomes. The Proteus effect was supported by immediate and next-day self-efficacy for core-muscle exercise only among female participants. The between-subject design allowed us to probe how avatar manipulation of muscular body shape with a six pack as opposed to normal body shape influences participants’ self-concept and exercise outcomes, as limited VR studies have employed within-subject comparisons. This also contributes to the literature by providing an upward comparison as opposed to the previous downward comparison regarding body fitness. The overall results supported the Proteus effect in the context of core-muscle exercise when comparing normal and ideal body shape avatars. However, the Proteus effect as an altered self-concept and its effects on self-efficacy for exercise were supported among females but not males. Whereas the female participants who embodied avatars with a six pack associated themselves more with the muscular concept than other people, the male participants who embodied avatars with a six pack perceived themselves as more normal than others. Theoretical and practical implications are discussed. (shrink)

Much of the excitement and concern with virtual reality (VR) has to do with the impact of virtual experiences on our moral conduct in the “real world”. VR technologies offer vivid simulations that may impact prosocial dispositions and abilities or emotions related to morality. Whereas some experiences could facilitate particular moral behaviors, VR could also inculcate bad moral habits or lead to the surreptitious development of nefarious moral traits. In this chapter, I offer an overview of the (...) ethical debate about using VR to improve morality. I start by clarifying the rationale of using VR for good, drawing on moral enhancement literature, branches of the science of morality, and the specific potentials of this technology. Then, I will briefly focus on three prominent domains of socio-moral improvement: the use of VR for enhancing empathy, reducing implicit biases, and improving pro-environmental behavior. After that, I shall consider three ethical objections to the enthusiasm for using VR in order to improve human morality. Finally, I will recapitulate the main points of the chapter and provide a few concluding thoughts on future avenues of discussion on how VR can make us act (morally) better. (shrink)

Economists usually assume that rational actions are the ones motivated by a self-interested agent. However in our daily life we often see people doing altruistic actions which we praise and which we do not call irrational. How can we account for this paradox? This question and the tension underlying it, is at the heart of Philip Pettit’s classic essay, “The Virtual Reality of Homo Economicus” (1995). This dissertation constitutes a detailed analysis and evaluation of the claims that Pettit (...) makes there, in particular his original proposal of reconciliation between economic science and common sense, and the role that self-interest occupies in his model. Despite its importance, there are still few written commentaries or critiques of Pettit’s essay (1995). Among the few, most concentrate on the thesis of resilience explanation that Pettit presents at the end of the essay. What is lacking in the literature is a thorough examination of the central claim that Pettit makes there, and which gives the title to his essay: namely, the thesis of the "virtual self-interested control". In my view, this constitutes one of the most sophisticated defences of the assumption of self-interest in rational choice theory and economics. Therefore, it is surprising that it has not been subjected to more discussion, and published research. In section 1, present some of the central concepts of rational choice theory and economics, namely the homo economicus. In section 2, I introduce Pettit’s model, and then evaluate in which sense it is a plausible model to explain the behaviour in non-market contexts. Section 3 presents my criticism of the shortcomings of the model. (shrink)

This paper aims to investigate the importance of literature in Maurice Merleau-Ponty’s reflections concerning two strictly connected phenomenological themes: 1) the virtuality of objects and of existence itself; 2) the genesis of truth and the intuition of essences. According to Merleau-Ponty, modern novelists have adopted a phenomenological method: instead of ‘explaining’ the world through words, they ‘show’ the lifeworld and its paradoxes indirectly. In his view, and against Jean-Paul Sartre’s position, analyzing literature means developing a theory integrating perception (...) and the imagination. Moreover, at the beginning of the 1950’s, this perspective led Merleau-Ponty to a deep revision of the Sartrian concepts of spontaneity and engagement in literary practice in favour of a theory of expression as style. As a conclusion, the paper argues for the key-role of literature in Merleau-Ponty’s indirect ontology as a way of rediscovering unity and harmony behind the metamorphosis of reality. (shrink)

As part of the 1995 IAPL meeting devoted to “Incorporations: Virtual Reality,” John Russon organized and chaired a session on the theme “Virtual Hegel.” Participants were asked to address the issue of Hegel and the postmodern, and to facilitate discussion their papers were circulated in advance.

Multi-user online environments involve millions of participants world-wide. In these online communities participants can use their online personas – avatars – to chat, fight, make friends, have sex, kill monsters and even get married. Unfortunately participants can also use their avatars to stalk, kill, sexually assault, steal from and torture each other. Despite attempts to minimise the likelihood of interpersonal virtual harm, programmers cannot remove all possibility of online deviant behaviour. Participants are often greatly distressed when their avatars are (...) harmed by other participants’ malicious actions, yet there is a tendency in the literature on this topic to dismiss such distress as evidence of too great an involvement in and identification with the online character. In this paper I argue that this dismissal of virtual harm is based on a set of false assumptions about the nature of avatar attachment and its relation to genuine moral harm. I argue that we cannot dismiss avatar attachment as morally insignificant without being forced to also dismiss other, more acceptable, forms of attachment such as attachment to possessions, people and cultural objects and communities. Arguments against according moral significance to virtual harm fail because they do not reflect participants’ and programmers’ experiences and expectations of virtual communities and they have the unintended consequence of failing to grant significance to attachments that we take for granted, morally speaking. Avatar attachment is expressive of identity and self-conception and should therefore be accorded the moral significance we give to real-life attachments that play a similar role. (shrink)

ABSTRACT In this article, we discuss the potential of Virtual Reality (VR) technologies for the creation and adaptation of stories aimed at children and young adult, focusing on the specificities of their usage protocols. We begin by introducing narratives in VR and their connection to the field of children and young adult literature. Subsequently, 360º videos targeted at children and young people are presented, along with the reading and engagement protocols that arise from their peculiarities. Starting from (...) the field of Cinematic Virtual Reality (CVR), we discuss about the main challenges posed by this medium for the enjoyment of immersive works, based on the analysis of the work Invasion!, produced by the Baobab studio. Thus, we conclude that both the production and reception of narratives in Virtual Reality presuppose the management of the viewer’s vision and attentional focus, considering the reading protocols already learned and naturalized through other media.

The main concepts of the free energy (FE) neuroscience developed by Karl Friston and colleagues parallel those of Freud's Project for a Scientific Psychology. In Hobson et al. ( 2014 ) these include an innate virtual reality generator that produces the fictive prior beliefs that Freud described as the primary process. This enables Friston's account to encompass a unified treatment—a complexity theory—of the role of virtual reality in both dreaming and mental disorder. In both accounts the (...) brain operates to minimize FE aroused by sensory impingements—including interoceptive impingements that report compliance with biological imperatives—and constructs a representation/model of the causes of impingement that enables this minimization. In Friston's account (variational) FE equals complexity minus accuracy, and is minimized by increasing accuracy and decreasing complexity. Roughly the brain (or model) increases accuracy together with complexity in waking. This is mediated by consciousness-creating active inference—by which it explains sensory impingements in terms of perceptual experiences of their causes. In sleep it reduces complexity by processes that include both synaptic pruning and consciousness/virtual reality/dreaming in REM. The consciousness-creating active inference that effects complexity-reduction in REM dreaming must operate on FE-arousing data distinct from sensory impingement. The most relevant source is remembered arousals of emotion, both recent and remote, as processed in SWS and REM on “active systems” accounts of memory consolidation/reconsolidation. Freud describes these remembered arousals as condensed in the dreamwork for use in the conscious contents of dreams, and similar condensation can be seen in symptoms. Complexity partly reflects emotional conflict and trauma. This indicates that dreams and symptoms are both produced to reduce complexity in the form of potentially adverse (traumatic or conflicting) arousals of amygdala-related emotions. Mental disorder is thus caused by computational complexity together with mechanisms like synaptic pruning that have evolved for complexity-reduction; and important features of disorder can be understood in these terms. Details of the consilience among Freudian, systems consolidation, and complexity-reduction accounts appear clearly in the analysis of a single fragment of a dream, indicating also how complexity reduction proceeds by a process resembling Bayesian model selection.

How do we assign values to virtual items, which include virtual objects, properties, events, subjects, worlds, environments, and experiences? In this article, I offer a framework for answering this question. After considering different value theses in the literature, I argue that whether we think these theses mutually exclusive or not turns on our view about the number of value-salient kinds virtual items belong to. Virtual monism is the view that virtual Xs belong to only (...) one value-salient kind in relation to X. Virtual pluralism is the view that they belong to more than one value-salient kind. I argue for two claims. First, virtual monism is mistaken. Minimally some virtual Xs are Xs, while others are not. Second, dualistic virtual pluralism is also mistaken because it is too coarse grained. Instead, I argue for fourfold pluralism: virtual items either represent an original's properties or reproduce essential properties and do so to lesser or greater extents. This gives us four value-salient kinds of virtual X: virtual reproductions, simulations, representations, and simulacra of X. I apply this view to various debates in the literature and conclude with a discussion of less basic hybrid kinds. (shrink)

Since the 2020 COVID-19 pandemic, the term virtual has become one of the most used in media and everyday speech. There is an increasing amount of research done on this new reality, and the results are still to be published. However, it is insufficiently known in scientific periodicals that the concept of virtual reality, enabled by information technology, has existed in the sociological literature since the 1990s when Castells introduced it to the theory of network (...) society. Therefore, the paper's primary goal is to consider basic concepts such as virtual reality, real virtuality, virtual communities, virtual sociability, and networked individualism. We will also briefly look at the forgotten classical notion of community as a fundamental form of sociability defined by the sociologist F. Tönnies, which re-enters the focus of scientific interest, without a clear and sociologically known classical definition. Starting from this framework, the paper examines the key question of whether these new virtual communities are indeed communities in the classical sense of the term or whether it is a form of networked individualism. Pojam virtualno je pojavom COVID-19 pandemije 2020., postao jedan od najkorištenijih u medijskom prostoru i u govoru svakodnevice. Sve je više i istraživanja o novoj stvarnosti, čiji rezultati se tek očekuju. Međutim, nedovoljno je poznato u domaćoj znanstvenoj periodici da koncept virtualne stvarnosti koju omogućava informacijska tehnologija, postoji u sociološkoj literaturi od devedesetih godina, kada ga u teoriju umreženog društva uvodi Castells. Stoga je glavni cilj rada prikazati i razmotriti neke osnovne pojmove kao npr. virtualna stvarnost, stvarna virtualnost, virtualne zajednice, virtualna društvenost i umreženi individualizam. Kratko ćemo se osvrnuti i na zaboravljeni klasični pojam zajednice kao temeljne forme društvenosti definirane od sociologa F. Tönniesa, koji ponovo ulazi u fokus znanstvenog interesa, bez jasne a u sociologiji poznate klasične definicije. Polazeći od tog okvira, u radu se propituje ključno pitanje, jesu li te nove virtualne zajednice uistinu zajednice u klasičnom smislu značenja pojma, ili je riječ o nekom obliku umreženog individualizma.

Impairment of spatial memory, including an inability to recall previous locations and navigate the world, is often one of the first signs of functional disability on the road to cognitive impairment. While there are many screening and diagnostic tools which attempt to measure spatial memory ability, they are often not representative of real-life situations and can therefore lack applicability. One potential solution to this problem involves the use of virtual reality, which immerses individuals in a virtually-simulated environment, allowing (...) for scenarios more representative of real-life without any of the associated risks. Here, we review the evidence surrounding the use of VR for the screening and diagnosis of spatial memory impairments, including potential limitations and how it compares to standard neuropsychological tests. We will also discuss the evidence regarding the potential use of VR in the rehabilitation of spatial memory deficits, which has not been well studied, but which could be game-changing if proven successful.

Nowadays virtual reality has gained extreme popularity among adolescents around the world, thanks to the possibility they offer to create a new life for their users. Especially for teenagers affected by the hikikomori syndrome, who experience struggles in establishing communication with others, virtual reality has become a tool to forsake their “adverse” reality, shaping fictitious safe environments and creating relationships with similar-minded users. This issue of virtual reality has been depicted in recent Japanese (...) animation, whose country is mostly affected by this issue. I will show mainly two approaches to the phenomenon: the one given in the anime series Sword Art Online (2012), in which virtual reality is perceived as the only place where true communication can happen; the second is the interpretation given by director Hosoda Mamoru in his animated features Summer Wars (2009) and Belle (2021), where virtual reality is a tool to support real life’s difficulties.

Virtual Reality Therapy has been shown to be effective in treating anxiety disorders and phobias, but has not yet been widely tested for Substance Use Disorders and it is not known whether health care practitioners working with SUDs would use VRT if it were available. We report the results of an interview study exploring practitioners’ and researchers’ views on the utility of VRT for SUD treatment. Practitioners and researchers with at least two years’ experience delivering or researching and (...) designing SUD treatments were recruited. Interviews were thematically analyzed, resulting in themes relating to the safety and realism of VRT, and the opportunity for the additional insight it could offer to during SUD treatment. Participants were positive about employing VRT as an additional treatment for SUD. VRT was thought suitable for treating adults and people with mental health issues or trauma, provided that risks were appropriately managed. Subsequent relapse, trauma and over-confidence in the success of treatment were identified as risks. The opportunity VRT offered to include other actors in therapy, and observe reactions, were benefits that could not currently be achieved with other forms of therapy. Overall, VRT was thought to offer the potential for safe, realistic, personalized and insightful exposure to diverse triggering scenarios, and to be acceptable for integration into a wide range of SUD treatments.

Erick J. Ramirez, Miles Elliott and Per‑Erik Milam (2021) have recently claimed that using Virtual Reality (VR) as an educational nudge to promote empathy is unethical. These authors argue that the influence exerted on the participant through virtual simulation is based on the deception of making them believe that they are someone else when this is impossible. This makes the use of VR for empathy enhancement a manipulative strategy in itself. In this article, we show that Ramirez (...) et al.’s ethical rejection of empathy enhancement through VR is based on confusion. First, we show that this misunderstanding stems from the conception of empathy-enhancing simulations solely as failed attempts at “being someone else,” along with ignoring the crucial difference between the psychological perspective-taking processes of imagine-other and imagine-self. Then, having overcome that misconception, we argue that the ethical misgivings about the use of VR to promote empathy should disappear and that these projects have greater potential for behavioural change than purely sympathy-focused interventions.

This paper compares the free energy neuroscience now advocated by Karl Friston and his colleagues with that hypothesised by Freud, arguing that Freud's notions of conflict and trauma can be understood in terms of computational complexity.

Movement abnormalities are prevalent across all stages of schizophrenia contributing to poor social functioning and reduced quality of life. To date, treatments are scarce, often involving pharmacological agents, but none have been shown to improve movement abnormalities effectively. Virtual reality (VR) is a tool used to simulate virtual environments where behavioral performance can be quantified safely across different tasks while exerting control over stimulus delivery, feedback and measurement in real time. Sensory information is transmittedviaa head mounted display (...) allowing users to directly interact with virtual objects and bodies using gestures and body movements in the real world to perform different actions, permitting a sense of immersion in the simulated virtual environment. Although, VR has been widely used for successful motor rehabilitation in a variety of different neurological domains, none have been exploited for motor rehabilitation in schizophrenia. The objectives of this article are to review movement abnormalities specific to schizophrenia, and how VR can be utilized to restore and improve motor functioning in patients with schizophrenia. Constructing VR-mediated motor-cognitive interventions that can help in retaining and transferring the learned outcomes to real life are also discussed. (shrink)

The subjects were randomly divided into two groups in equal numbers, and they alternately viewed two types of VR images themed on the mid- to late Showa era in Japan. In group A, the CG images were viewed first, and then the LA images were viewed. In group B, the images were viewed in the opposite order. Before VR viewing, subjects responded to Mini-Mental State Examination Japanese version and State-Trait Anxiety Inventory Japanese version. After viewing the first and second VR, subjects responded to STAI and the numerical rating scale for satisfaction and side effects.Results: Ten subjects participated in this study. The values of analyses are presented in the mean. The age was 87.1 years, and the MMSE was 28.5. The total STAI score before VR viewing was 36.1, but it significantly decreased to 26.8 after the first VR viewing, and further decreased to 23.4 after the second VR viewing. The NRS score for satisfaction tended to be higher after viewing LA in group A vs. 8.6, P = 0.0993), while in group B, the score after CG was slightly lower than that after LA. There were no serious side effects.Conclusions: This study suggests that iVR reminiscence can reduce anxiety in the oldest-old without causing serious side effects. Furthermore, the impacts might be better with LA images. (shrink)

The combination of COVID-19 and the Fourth Industrial Revolution has brought an unprecedented new normal, which has affected all aspects of human life, including religious activities. As a consequence, church mission and different ministries have found themselves more dependent on media. Furthermore, the convergent digital technology continually develops augmented reality and virtual reality, in which churches are planted and continue to carry out their mission and ministries. Although virtual reality churches are new mission frontiers in (...) the digital age, there are several theological issues from the conventional perspective of church ministry and mission. This paper aims to address the controversial theological issues and reflect on them from an ecclesiological perspective to explore a theological possibility to overcome the issues and to justify their mission and ministries in virtual reality.

In this article, we apply the literature on the ethics of choice-architecture (nudges) to the realm of virtual reality (VR) to point out ethical problems with using VR for empathy-based nudging. Specifically, we argue that VR simulations aiming to enhance empathic understanding of others via perspective-taking will almost always be unethical to develop or deploy. We argue that VR-based empathy enhancement not only faces traditional ethical concerns about nudge (autonomy, welfare, transparency), but also a variant of the (...) semantic variance problem that arises for intersectional perspective-taking. VR empathy simulations deceive and manipulate their users about their experiences. Despite their often laudable goals, such simulations confront significant ethical challenges. In light of these goals and challenges, we conclude by proposing that VR designers shift from designing simulations aimed at producing empathic perspective-taking to designing simulations aimed at generating sympathy. These simulations, we claim, can avoid the most serious ethical issues associated with VR nudges, semantic variance, and intersectionality. (shrink)

The depths of the sea, their obscure inhabitants and their mysteries have always been a rich source of myths and metaphors for authors and philosophers. Fables about giant squids and monstrous octopuses run through the history of literature and culture. The vampire squid is only a small phylogenetic relic, but it provides a useful model for Flusser's hybrid philosophical fiction Vampyroteuthis Infernalis. Flusser slips metaphorically into the creature’s gelatinous skin in order to speculate on the paradigms of postmodern life, (...) measuring the abyss from the inside and producing a very peculiar, experimental form of thinking and writing. In the present era of virtual reality and computer simulations, we experience fiction as the only reality. According to Vaihinger's definition, fiction is a useful construct that is precisely not real, but enables human beings to create and manipulate their environments. His philosophy of “as if” is perhaps the fullest expression of fictionalism and shows its ambivalent potential. (shrink)

Immersive virtual environments can produce a state of behaviour referred to as ‘presence’, during which the individual responds to the virtual environment as if it were real. Presence can be arranged to scientifically evaluate and affect our consciousness within a controlled virtual environment. This phenomenon makes the use of virtual environments amenable to existing and in-development forms of therapy for various conditions. Delirium in the intensive care unit (ICU) is one such condition for which virtual (...) reality (VR) technology has not been evaluated to date. We are currently assessing the feasibility and utility of a delirium prevention and treatment system, which implements VR to improve quality of sleep, reduce pain, lower usage of sedatives, and stimulate cognition. The proposed system will consist of 3-axis wearable accelerometers, 6-DOF position trackers, a VR system and apps designed to promote sleep quality and mindfulness. Our a priori hypothesis is that our VR therapy system would lower the occurrence of delirium in patients admitted to ICUs. (shrink)

Since literary historian Robert Bone published his seminal essay ‘Richard Wright and the Chicago Renaissance’ in 1986, scholars have created new cartographies of previously unexplored terrain in American cultural history. The earliest studies focused on literature, but more recently attention has turned to other disciplines, including visual arts. Recent publication of The Muse in Bronzeville: African American Creative Expression in Chicago, 1932–1950 (2011) by Robert Bone and Richard A. Courage promises to decisively broaden scholarly understandings of the scope and (...) significance of Chicago-centred cultural production during the Great Depression and post-war years. Of particular relevance to contemporary studies of new media art is the manner in which then-emergent ideas and practices – centring on racialized subject matter, elite and mass audiences, traditional and new mediums of expression, private vs public sponsorship, and passive vs active reception of art objects – converged to create new paradigms and possibilities for visual artists to reshape consciousness in a period of institutional collapse and change. Chicago’s New Negro artists of the 1930s and 1940s, like their counterparts in 1920s Harlem, sought to reframe perceptions of African American life, to re-present the black subject as something other than an object of contempt or amusement beneath the privileged gaze of the white viewer. Just as these artists sought to revise perceptions of racial reality, examination of the wide range of actual images they created and the mediums and styles they explored revises reductive notions about creative expression in this period, which often portray a mere subordination of art to propaganda and an embrace of representational aesthetics and simplistic narratives in a fruitless detour in the evolution from modernism to postmodernism. On the contrary, Andrew Hemingway notes the range of stylistic experiment and characterizes so-called ‘social art’ as ‘a hybrid and unstable mode [which] had to carry the imperative to be an art equal in formal achievement to both the great art of the past and the modern tradition … [and] to suggest a political orientation without becoming overt revolutionary propaganda’ (2002).New media theorist Oliver Grau observes thatIn many quarters, virtual reality is viewed as a totally new phenomenon… but it did not make its first appearance with the technical invention of computer-aided virtual realities. On the contrary, virtual reality forms part of the core of the relationship of humans to images… grounded in art traditions that have receivedscant attention up to now.(2004)In the midst of another period of change, of transformed and transforming ideas and practices in the arts, we have much to learn from the attempts of Chicago’s New (Media) Negro artists to create ‘art for the people’, to immerse broad audiences in such accessible media as mural painting, photography and graphic arts.

Background: The new human coronavirus that leads to COVID-19 has spread rapidly around the world and has a high degree of lethality. In more severe cases, patients remain hospitalized for several days under treatment of the health team. Thus, it is important to develop and use technologies with the aim to strengthen conventional therapy by encouraging movement, physical activity, and improving cardiorespiratory fitness for patients. In this sense, therapies for exposure to virtual reality are promising and have been (...) shown to be an adequate and equivalent alternative to conventional exercise programs.Aim: This is a study protocol with the aim of comparing the conventional physical therapy intervention with the use of a non-immersive VR software during COVID-19 hospitalization.Methods: Fifty patients hospitalized with confirmed diagnosis of COVID-19 will be divided in two groups under physiotherapy treatment using conventional or VR intervention: Group A: participants with COVID-19 will start the first day of the protocol with VR tasks in the morning and then in the second period, in the afternoon, will perform the conventional exercises and Group B: participants with COVID-19 will start the first day with conventional exercises in the morning and in the second period, in the afternoon, will perform activity with VR. All participants will be evaluated with different motor and physiologic scales before and after the treatment to measure improvements.Conclusion: Considering the importance of benefits from physical activity during hospitalization, VR software shows promise as a potential mechanism for improving physical activity. The results of this study may provide new insights into hospital rehabilitation.Trial Registration:ClinicalTrials.gov, identifier: NCT04537858. Registered on 01 September 2020. (shrink)

The history of humankind is full of examples that indicate a constant desire to make human beings more moral. Nowadays, technological breakthroughs might have a significant impact on our moral character and abilities. This is the case of Virtual Reality (VR) technologies. The aim of this paper is to consider the ethical aspects of the use of VR in enhancing empathy. First, we will offer an introduction to VR, explaining its fundamental features, devices and concepts. Then, we will (...) approach the characterization of VR as an “empathy machine,” showing why this medium has aroused so much interest and why, nevertheless, we do not believe it is the ideal way to enhance empathy. As an alternative, we will consider fostering empathy-related abilities through virtual embodiment in avatars. In the conclusion, however, we will, we will examine some of the serious concerns related to the ethical relevance of empathy and will defend the philosophical case for a reason-guided empathy, also suggesting specific guidelines for possible future developments of empathy enhancement projects through VR embodied experiences.

It is controversial whether virtual reality should be considered fictional or real. Virtual fictionalists claim that objects and events within virtual reality are merely fictional: they are imagined and do not exist. Virtual realists argue that virtual objects and events really exist. This metaphysical debate might appear important for some of the practical questions that arise regarding how to morally evaluate and legally regulate virtual reality. For instance, one advantage claimed of (...) virtual realism is that only by taking virtual objects and events to be real can we explain our strong emotional reactions to certain virtual actions, as well as their potential immorality. This paper argues that emotional reactions towards, and wrongs within, virtual reality are consistent with its being merely fictional. The emotional and ethical judgments we wish to make regarding virtual reality do not provide any grounds for preferring virtual realism. (shrink)

African literature has played a major role in changing and shaping perceptions about African people and their way of life for the longest time. Unlike western cultures that are associated with advanced forms of writing, African literature is oral in nature, meaning it has to be recited and even performed. Although Africa has an old tribal culture, African philosophy is a new and strange idea among us. Although the problem of “universality” of African philosophy actually refers to the (...) question of whether Africa has heckling of philosophy in the Western sense, obviously, the philosophy bred by Africa’s native culture must be acknowledged. Therefore, the human–computer interaction-oriented method is proposed to appreciate African literature and African philosophy. To begin with, a physical object of tablet-aid is designed, and a depth camera is used to track the user’s hand and tablet-aid and then map them to the virtual scene, respectively. Then, a tactile redirection method is proposed to meet the user’s requirement of tactile consistency in head-mounted display virtual reality environment. Finally, electroencephalogram emotion recognition, based on multiscale convolution kernel convolutional neural networks, is proposed to appreciate the reflection of African philosophy in African literature. The experimental results show that the proposed method has a strong immersion and a good interactive experience in navigation, selection, and manipulation. The proposed HCI method is not only easy to use, but also improves the interaction efficiency and accuracy during appreciation. In addition, the simulation of EEG emotion recognition reveals that the accuracy of emotion classification in 33-channel is 90.63%, almost close to the accuracy of the whole channel, and the proposed algorithm outperforms three baselines with respect to classification accuracy.
