This handbook brings together essays in the philosophy of film and motion pictures from authorities across the spectrum. It boasts contributions from philosophers and film theorists alike, with many essays employing pluralist approaches to this interdisciplinary subject. Core areas treated include film ontology, film structure, psychology, authorship, narrative, and viewer emotion. Emerging areas of interest, including virtual reality, video games, and nonfictional and autobiographical film also have dedicated chapters. Other areas of focus include the film medium’s intersection (...) with contemporary social issues, film’s kinship to other art forms, and the influence of historically seminal schools of thought in the philosophy of film. Of emphasis in many of the essays is the relationship and overlap of analytic and continental perspectives in this subject. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Journal of Aesthetic Education 37.4 (2003) 58-64 [Access article in PDF] Media Literacy Education in Art:Motion Expression and the New Vision of Art EducationThe Bauhaus, which established the foundation of modern design, has greatly influenced Japanese design and art education. It is a historical fact that the movement views "synthetic art" as an integration of the various fields and the integration of the art and machine technology (...) experimentally. However, the Bauhaus is not just of historical importance but continues to have an influence even in the integration of the art and electronic technology in today's "multimedia." In addition, it can be said that it is very much alive as "the digital Bauhaus" or "the electronic Bauhaus." 1 As we know, today's multimedia and the Internet give us a new life-environment, and expandthe possibility of expression in art. Therefore, current art education must examine how these new medias will be incorporated into the curriculum.In the cases of the photograph, video, or computer, an expression by the image media is added to the art course for the junior high school course of study. 2 Also in school art classes, image media was introduced, expanding the possibilities of self-expression through art. This result can be matched to the needs of the industrial world in Japan as well. As an educational practice, the content of this course of study is promising, even though someproblems must be solved, acquiring new equipment, re-educating the artteacher, and securing additional art school hours. The new content in art education can be summarized as follows:1. The motion picture (animation) which includes time and movement. Motion picture is asequence of continuous images, obviously different from the still images of painting. There are, of course, artworks that express motion or induce the viewer'seye movement. There are also kinetic artworks that do move, such as mobiles. Works of motion picture have, however, a fixed time shaft, and they are formed by the afterimage phenomenon. Thinking about the progress of time shaft is an indispensable element for the production. [End Page 58]2. The synchronism of image and sound. Because time is a factor in the visual expression, the works are compatible with music — the art of time. There is a synchronized relation between the motion picture and music. Image expression with multimedia became synthetic art, just as the Bauhaus looked for "architecture." Currently, this kind of expression transitions from art to entertainment, and permeates daily life.3. The method with interactive art work. Not only artworks of installation, but also TV games and web design have interactive construction as an indispensable interface. The aesthetic value of these visual works will be appreciated when the user starts the action by hitting a touchpad, pushing buttons, or clicking a mouse. To make this kind of artwork, one needs to consider the latent relationships between humans and work, and establish the input-output order for the method of construction.4. The problem of virtual reality. The term "virtual reality" is used by some art teachers as criticism against digital works such as computer graphics. These teachers insist that there is no reality there. One can, however, get an aesthetic feeling through sensory information, imagination, and sensitivity, even though what one sees is an illusion. The feeling of reality a picture of an apple gives, for example, may be equal to a computer graphic apple.Human imagination also creates "virtual reality" beyond reality in the myth, the novel, and so on. It can be said that this is the basis for human creativity.Furthermore, expression by image media raises the problem of a "reality" in which material experience is important to encounterthe world directly. Such an argument discusses multimedia as a tool of expression and a teaching material while reconsidering human reality.More recently, "media literacy" (ability to read and understand media) became an important point of discussion for Japanese educators. Usually, in this discussion, the critical ability to talk back to the television program is emphasized. However, through art... (shrink)

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.

Motion pose capture technology can effectively solve the problem of difficulty in defining character motion in the process of 3D animation production and greatly reduce the workload of character motion control, thereby improving the efficiency of animation development and the fidelity of character motion. Motion gesture capture technology is widely used in virtual reality systems, virtual training grounds, and real-time tracking of the motion trajectories of general objects. This paper proposes an (...) attitude estimation algorithm adapted to be embedded. The previous centralized Kalman filter is divided into two-step Kalman filtering. According to the different characteristics of the sensors, they are processed separately to isolate the cross-influence between sensors. An adaptive adjustment method based on fuzzy logic is proposed. The acceleration, angular velocity, and geomagnetic field strength of the environment are used as the input of fuzzy logic to judge the motion state of the carrier and then adjust the covariance matrix of the filter. The adaptive adjustment of the sensor is converted to the recognition of the motion state. For the study of human motion posture capture, this paper designs a verification experiment based on the existing robotic arm in the laboratory. The experiment shows that the studied motion posture capture method has better performance. The human body motion gesture is designed for capturing experiments, and the capture results show that the obtained pose angle information can better restore the human body motion. A visual model of human motion posture capture was established, and after comparing and analyzing with the real situation, it was found that the simulation approach reproduced the motion process of human motion well. For the research of human motion recognition, this paper designs a two-classification model and human daily behaviors for experiments. Experiments show that the accuracy of the two-category human motion gesture capture and recognition has achieved good results. The experimental effect of SVC on the recognition of two classifications is excellent. In the case of using all optimization algorithms, the accuracy rate is higher than 90%, and the final recognition accuracy rate is also higher than 90%. In terms of recognition time, the time required for human motion gesture capture and recognition is less than 2 s. (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.

This is the first book to present an aesthetics of virtual reality media. It situates virtual reality media in terms of the philosophy of the arts, comparing them to more familiar media such as painting, film and photography. When philosophers have approached virtual reality, they have almost always done so through the lens of metaphysics, asking questions about the reality of virtual items and worlds, about the value of such things, and indeed, (...) about how they may reshape our understanding of the "real" world. Grant Tavinor finds that approach to be fundamentally mistaken, and that to really account for virtual reality, we must focus on the medium and its uses, and not the hypothetical and speculative instances that are typically the focus of earlier works. He also argues that much of the cultural and metaphysical hype around virtual reality is undeserved. But this does not mean that virtual reality is illusory or uninteresting; on the contrary, it is significant for the altogether different reason that it overturns much of our understanding of how representational media can function and what we can use them to achieve. The Aesthetics of Virtual Reality will be of interest to scholars and advanced students working in aesthetics, philosophy of art, philosophy of technology, metaphysics, and game studies. (shrink)

Sensorimotor learning refers to improvements that occur through practice in the performance of sensory-guided motor behaviors. Leveraging novel technical capabilities of an immersive virtual environment, we probed the component kinematic processes that mediate sensorimotor learning. Twenty naïve subjects performed a simulated marksmanship task modeled after Olympic Trap Shooting standards. We measured movement kinematics and shooting performance as participants practiced 350 trials while receiving trial-by-trial feedback about shooting success. Spatiotemporal analysis of motion tracking elucidated the ballistic and refinement phases (...) of hand movements. We found systematic changes in movement kinematics that accompanied improvements in shot accuracy during training, though reaction and response times did not change over blocks. In particular, we observed longer, slower, and more precise ballistic movements that replaced effort spent on corrections and refinement. Collectively, these results leverage developments in immersive virtual reality technology to quantify and compare the kinematics of movement during early learning of full-body sensorimotor orienting.

A timely book that uses science fiction to provoke reflection and discussion on philosophical issues From the nature of mind to the ethics of AI and neural enhancement, science fiction thought experiments fire the philosophical imagination, encouraging us to think outside of the box about classic philosophical problems and even to envision new ones. Science Fiction and Philosophy explores puzzles about virtual reality, transhumanism, whether time travel is possible, the nature of artificial intelligence, and topics in neuroethics, among (...) other timely issues. This thought-provoking volume is suitable for students and general readers but also examines new and more advanced topics of interest to seasoned philosophers and scientists.

Comprehensively improving the level of vocational education and teaching quality has become an important initiative to meet the new round of technological revolution and industrial change. The traditional teaching mode can no longer meet the needs of industries and enterprises for job competences, and all higher education institutions are actively thinking about how to carry out teaching reform. Virtual reality can effectively solve the above-mentioned drawbacks, but the hardware facilities of the existing VR systems are extremely expensive, making (...) it impossible to popularize it in teaching. In this context, this paper is based on VR for the design of an interactive teaching platform. This paper discusses the key technologies of virtual reality, introduces the relevant theoretical foundation, and describes the current virtual reality devices with high popularity and their advantages and disadvantages for systematic analysis. From the perspective of teaching design, the design of human-computer interaction teaching process using VR technology to develop learning scenes is studied, introducing 3D modeling techniques, model construction, the production of picture and text panels, the production of video materials, and the establishment of virtual tour guide 3D scenes. The principle of this paper is to build a 3D vision for building 3D views of educational needs to design high quality images and video animation using 3DMAX and unity 3D engines. Then, we introduce the use of VR glasses, smart phones, and Bluetooth wireless handle to build a simple interactive teaching platform; the platform is of low cost of construction and student coverage, to solve the teaching resources shortage, equipment conditions lagging behind, the curriculum content aging, teachers and students who cannot interact in real time, and a series of problems.

Purpose:Human navigation skills are essential for everyday life and rely on several cognitive abilities, among which visual-spatial competences that are impaired in subjects with cerebral palsy. In this work, we proposed navigation tasks in immersive virtual reality to 15 children with CP and 13 typically developing peers in order to assess the individual navigation strategies and their modifiability in a situation resembling real life.Methods:We developed and adapted to IVR an application based on a 5-way maze in a playground (...) that was to be navigated to find a reward. The learning process, navigation strategies, and adaptation to changes were compared between participants with CP and their TD peers and correlated with visual-spatial abilities and cognitive competences.Results:Most participants with CP needed more attempts than TD participants to become proficient in navigation. Furthermore, the learning phase was correlated to visual-spatial memory but not with cognitive competences. Interestingly, navigation skills were comparable between groups after stabilization. While TD participants mainly relied on allocentric strategies based on environmental cues, egocentric strategies based on body motion prevailed in participants with CP. Furthermore, participants with CP had more difficulties in modifying their navigation strategies, caused by difficulties in executive processes beyond the visual-perceptual impairment, with an inefficient shift between implicit and explicit competences.Conclusions:The navigation abilities in participants with CP seem to be different from their TD peers in terms of learning and adaptation to new conditions; this could deeply affect their everyday life and ultimately participation and inclusion. A regular assessing and focused rehabilitative plans could help to better navigate the environment and affect self-perception. (shrink)

The ability to quickly and accurately recognise emotional states is adaptive for numerous social functions. Although body movements are a potentially crucial cue for inferring emotions, few studies have studied the perception of body movements made in naturalistic emotional states. The current research focuses on the use of body movement information in the perception of fear expressed by targets in a virtual heights paradigm. Across three studies, participants made judgments about the emotional states of others based on motion-capture (...) body movement recordings of those individuals actively engaged in walking a virtual plank at ground-level or 80 stories above a city street. Results indicated that participants were reliably able to differentiate between height and non-height conditions (Studies 1 & 2), were more likely to spontaneously describe target behaviour in the height condition as fearful (Study 2) and their fear estimates were highly calibrated with the fear ratings from the targets (Studies 1-3). Findings show that VR height scenarios can induce fearful behaviour and that people can perceive fear in minimal representations of body movement. (shrink)

In this book, Grant Tavinor, well known for his influential work on the aesthetics of videogames, offers the first focused study of the aesthetics of virtual reality media. When reading the first pages, one cannot help but notice Tavinor’s enthusiasm about virtual reality (VR) in the vivid descriptions of his explorations of virtual haunted houses, distant planets, and ancient Rome. These descriptions also reveal Tavinor’s refreshing aim to focus on present uses of VR media, instead (...) of the so-called “perfect virtual realities” (virtual realities that are indistinguishable from the actual world) that are often the focus of philosophical discussions. When talking about VR, philosophers indeed often target hypothetical situations in which people are brains in vats, hooked up to experience machines, or living in a world that is, unbeknownst to them, merely a simulated one. Tavinor, however, intends to avoid metaphysical or ontological questions about hypothetical virtual realities, instead focusing on our aesthetic experiences of concrete VR media. With this, he generally refers to “immersive, interactive, and computable VR technologies” (p. 15), such as the HTC Vive, the PlayStation VR, and the Oculus, which depict virtual environments through head mounted displays. Tavinor’s aim is to show how these systems are media that allow for “a technologically fancy kind of picturing” (p. 12), and to contextualize them in the history of representational media alongside of painting, photography, and film.

Tractatus Logico-Pilosophicus, the only book published during Ludwig Wittgenstein's lifetime , has since attracted the imagination of generations of philosophers as a work of great philosophical genius. Nonetheless, even today, more than eighty years later, philosophers are struggling to reconcile its diverse themes within a single, coherent picture. The present work is an attempt to meet this challenge. ;Wittgenstein considered the single proposition as a concrete model for the fact. The challenge is to show how a system of propositions can (...) serve as a model of reality. My work concentrates on three pillars of the logic of the Tractatus: the picture theory, negation as "reversal of sense," the independence of elementary propositions. Using a simple scenario of the ordering of objects or letters on a line, I examine the conflict generated by the attempt to adequately accommodate all three themes and offer my own solution. My solution brings implications to the problem of negation and to the Tractatus's thesis that the possibilities of logical space are spanned by the possible configurations of the ultimately simple objects. One such implication, which stands in contrast to the common reading, is that in atomic facts we have 'complex objects' as constituents. ;The resolution offered, furthermore, exposes an intrinsic difficulty in the Tractatus, for which I have reserved the term arbitrary choice. The difficulty is manifested in the lack of assurance---from the perspective of logic---that a concept-word will preserve its 'standard' meaning when it is reapplied or when its scope of application varies. In this I uncover the seed of central themes in Wittgenstein's later philosophy, e.g. the rule-following argument, as present already in the Tractatus. ;In the concluding chapter, I suggest a new account for the nature of the proposition by connecting the analysis offered in the Tractatus with the subject of time and motion. The picture with which the work concludes then considers language not as corresponding to reality, but as engaged or synchronized with reality---if you will, it is a picture of language and reality in a dance.

ObjectiveVirtual reality grasping exercise training helps patients participate actively in their recovery and is a critical approach to the rehabilitation of hand dysfunction. This study aimed to explore the effects of active participation and VR grasping on brain function combined with the kinematic information obtained during VR exercises.MethodsThe cerebral oxygenation signals of the prefrontal cortex, the motor cortex, and the occipital cortex were measured by functional near-infrared spectroscopy in 18 young people during the resting state, grasping movements, and VR (...) grasping movements. The EPPlus plug-in was used to collect the hand motion data during simulated interactive grasping. The wavelet amplitude of each cerebral cortex and the wavelet phase coherence of each pair of channels were calculated by wavelet analysis. The total difference in acceleration difference of the hand in the VR grasping movements was calculated to acquire kinematic characteristics. The cortical activation and brain functional connectivity of each brain region were compared and analyzed, and a significant correlation was found between VR grasping movements and brain region activation.ResultsCompared with the resting state, the WA values of LPFC, RPFC, LMC, RMC, and ROC increased during the grasping movements and the VR grasping movements, these changes were significant in LPFC and LMC. The WA values of LMC in the VR grasping movements were significantly higher than those in the grasping movements. The WPCO of the cerebral cortex increased during grasping exercise compared with the resting state. Nevertheless, the number of significant functional connections during VR grasping decreased significantly, and only the WPCO strength between the LPFC and LMC was enhanced. The increased WA of the LPFC, RPFC, LMC, and RMC during VR grasping movements compared with the resting state showed a significant negative correlation with KCs.ConclusionThe VR grasping movements can improve the activation and FC intensity of the ipsilateral brain region, inhibit the FC of the contralateral brain region, and reduce the quantity of brain resources allocated to the task. Thus, ordered grasping exercises can enhance active participation in rehabilitation and help to improve brain function. (shrink)

Atypical sensorimotor developmental trajectories greatly contribute to the profound heterogeneity that characterizes Autism Spectrum Disorders. Individuals with ASD manifest deviations in sensorimotor processing with early markers in the use of sensory information coming from both the external world and the body, as well as motor difficulties. The cascading effect of these impairments on the later development of higher-order abilities underlines the need for interventions that focus on the remediation of sensorimotor integration skills. One of the promising technologies for such stimulation (...) is Immersive Virtual Reality. In particular, head-mounted displays have unique features that fully immerse the user in virtual realities which disintegrate and otherwise manipulate multimodal information. The contribution of each individual sensory input and of multisensory integration to perception and motion can be evaluated and addressed according to a user’s clinical needs. HMDs can therefore be used to create virtual environments aimed at improving people’s sensorimotor functioning, with strong potential for individualization for users. Here we provide a narrative review of the sensorimotor atypicalities evidenced by children and adults with ASD, alongside some specific relevant features of IVR technology. We discuss how individuals with ASD may interact differently with IVR versus real environments on the basis of their specific atypical sensorimotor profiles and describe the unique potential of HMD-delivered immersive virtual environments to this end.

Self-motion through space generates a visual pattern called optic flow. It can be used to determine one’s direction of self-motion (heading). Previous studies have already shown thatthis perceptual ability, which is of critical importance during everyday life, changes with age. In most of these studies subjects were asked to judge whether they appeared to be heading to the left or right of a target. Thresholds were found to increase continuously with age. In our current study, we were interested (...) in absolute rather than relative heading judgements and in the question about a potential neural correlate of an age-related deterioration of heading perception. Two groups, older test subjects and younger controls, were shown optic flow stimuli in a virtual-reality setup. Visual stimuli simulated self-motion through a 3-D cloud of dots and subjects had to indicate their perceived heading direction after each trial. In different subsets of experiments we varied individuallyrelevant stimulus parameters: presentation time, number of dots in the display, stereoscopic vs. non-stereoscopic stimulation, and motion coherence. We found decrements in heading performance with agefor each stimulus parameter. In a final step we aimed to determine a putative neural basis of this behavioural decline. To this end we modified a neural network model which previously has proven to be capable of reproduce and predict certain aspects of heading perception. We show that the observed data can be modeled by implementing an age related neuronal cell loss in this neural network. We conclude that a continuous decline of certain aspects of motion perception, among them heading, might directly be based on anage-related progressive loss of groups of neurons being activated by visual motion.

A central debate in the philosophy of virtual reality (VR) focuses on the reality of virtual items. Broadly, there are two main disagreements. Some views accept a metaphysical orientation to VR, and disagree on the reality of virtual items. For instance, David Chalmers (Disputatio 9(46):309-352, 2017, Disputatio 11(55):453- 486, 2019, 2022) defends digitalism, the view that virtual items are real digital items. Neil McDonnell & Nathan Wildman (Disputatio 11(55):371-397, 2019), by contrast, defend fictionalism, (...) which maintains that virtual items are unreal fictions. Other views, like Grant Tavinor’s (2021), reject the metaphysical orientation, argu- ing that focusing on the reality of virtual items is a mistake. In what follows I evalu- ate these two disagreements. I argue that experiences of virtual items depend on episodes of picture perception. Recognizing this reveals that the current debates are either easily resolved in favor of one view, or are not disagreeing about the reality of virtual items, but about what virtual items are.

Reality has become an increasingly prominent topic in contemporary philosophy. The book’s contributors are responding to the challenge to use the philosophically underexplored potential of film to disclose what the editors propose to call “the real of reality.”.

In formulating a notion of filmic reality, The Reality of Film offers a novel way of understanding our relationship to cinema. It argues that cinema need not be understood in terms of its capacities to refer to, reproduce or represent reality, but should be understood in terms of the kinds of realities it has the ability to create. The Reality of Film investigates filmic reality by way of six key film theorists: André Bazin, Christian Metz, (...) Stanley Cavell, Gilles Deleuze, Slavoj Zizek and Jacques Rancière. In doing so, it provides comprehensive introductions to each of these thinkers, while also debunking many myths and misconceptions about them. Along the way, a notion of filmic reality is formed that radically reconfigures our understanding of cinema. This book is essential reading for film scholars, students and philosophers of film, while it will also appeal to graduate students and specialists in other fields. (shrink)

In this article, we will attempt to understand Sellars’ puzzling notion of ‘adequate picturing’ and its relation to the Sellarsian ‘conceptual order’ through Spinoza’s intuitive knowledge. First, it will be suggested that there are important structural similarities between Sellarsian ‘adequate picturing’ and Spinoza’s intuitive knowledge which can illuminate some ‘dark’ and not so well understood features of Sellarsian picturing. However, there remain some deep differences between Sellars’ and Spinoza’s philosophy, especially with regard to their notion of ‘adequacy’ and the sense (...) in which an idea can be said to ‘correspond’ with its object. As a consequence of those differences it turns out that, from a Sellarsian viewpoint, Spinoza’s notion of intuitive knowledge is a version of the myth of the Given. However, Sellars’ own proposed way out of the Myth has problematic consequences by Sellars’ own lights: His sharp distinction between the ‘space of reasons’ level and the level of picturing makes the Sellarsian vision of the ‘stereoscopic fusion’ of those levels virtually unintelligible. Finally, it will be argued that a non-standard interpretation of Spinoza’s intuitive knowledge -proposed in Baltas -, combined with a Sellars-inspired bifurcated understanding of Dreyfusian expert knowledge, can provide the means 1) for constructing a notion of intuitive knowledge that evades the myth of the Given, and, 2) for making full sense of the claim that the ‘space of reasons’ dimension of understanding the world can in principle be fused with the ‘picturing’ dimension and provide us with a single complex coherent experience of reality and our place in it.

How can human experience, vibrant with colours, sounds, flavours, emotions and meanings, arise from the skeletal dance of matter depicted in the physical sciences? Today the mind-body problem confronts not only metaphysicians and moral philosophers, but also workers in the fields of cognitive science, artificial intelligence and neuroscience. Paul Marshall offers a radical solution to the mind-body problem by rejecting the idea of a purely material world and asserting instead the primacy of experience. As many have recognized before, experience is (...) not reducible to material bodies and processes alone. Marshall goes a step further and suggests that the matter investigated by modern science corresponds to structural features of an experiential universe that supports and includes our familiar experiences. Utilizing clues furnished by mystical experience and responding to a challenge posed by the physics of motion, Marshall takes up Leibniz's philosophy of 'living mirrors' and arrives at a holistic world-picture that has suggestive links with quantum physics and the visionary cosmologies of East and West.

A central question in neuroscience and psychology is how the mammalian brain represents the outside world and enables interaction with it. Significant progress on this question has been made in the domain of spatial cognition, where a consistent network of brain regions that represent external space has been identified in both humans and rodents. In rodents, much of the work to date has been done in situations where the animal is free to move about naturally. By contrast, the majority of (...) work carried out to date in humans is static, due to limitations imposed by traditional laboratory based imaging techniques. In recent years, significant progress has been made in bridging the gap between animal and human work by employing Virtual Reality (VR) technology to simulate aspects of real-world navigation. Despite this progress, the VR studies often fail to fully simulate important aspects of real-world navigation, where information derived from self-motion is integrated with representations of environmental features and task goals. In the current review, we provide a brief overview of animal and human imaging work to date, focusing on commonalties and differences in findings across species. Following on from this we discuss VR studies of spatial cognition, outlining limitations and developments, before introducing mobile brain imaging techniques and describe technical challenges and solutions for real-world recording. Finally, we discuss how these advances in mobile brain imaging technology, provide an unprecedented opportunity to illuminate how the brain represents complex multifaceted information during naturalistic navigation.

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.

Human motion gesture recognition is the most challenging research direction in the field of computer vision, and it is widely used in human-computer interaction, intelligent monitoring, virtual reality, human behaviour analysis, and other fields. This paper proposes a new type of deep convolutional generation confrontation network to recognize human motion pose. This method uses a deep convolutional stacked hourglass network to accurately extract the location of key joint points on the image. The generation and identification part (...) of the network is designed to encode the first hierarchy and the second hierarchy and show the spatial relationship of human body parts. The generator and the discriminator are designed as two parts in the network, and they are connected together in order to encode the possible relationship of appearance and, at the same time, the possibility of the existence of human body parts and the relationship between each part of the body and its parental part coding. In the image, the key nodes of the human body model and the general body posture can be identified more accurately. The method has been tested on different data sets. In most cases, the results obtained by the proposed method are better than those of other comparison methods. (shrink)

Communication is a crucial component of scientific activity (as of virtually any other domain of human activity, especially in this "communication age" in which we live). As researchers and as citizens, we should all be concerned with the communication of science as well as with communication within science. In this paper, I will deal with one of the key aspects of this topic ג€“ the question whether scientific communication is or should be ג€�transparentג€�. The view that this is or should (...) be the case is often taken for granted both by scientists and the general public. I will challenge this view and suggest that we should learn to live without the illusion that scientific communication is or should be transparent. This idea is closely related, if not derived from, the traditional epistemological conception according to which scientific method is the privileged tool we have for penetrating beyond appearances and discovering the true ג€�nature of thingsג€�, in terms of which all observable phenomena should be ultimately explained. Applying the scientific method should, thus, yield a fully intelligible representation of the world, which in its turn should be transparently communicable. The trouble with this enticing ideal is that it does not correspond to actual practice. Again and again we experience the fact that the ג€�true picture of the worldג€� remains veiled for everyone but a small group of initiated experts in a narrow domain. Is this only a technical problem having to do with the phenomenon of specialization and with the inevitable complexity of the language(s) of science, as it is often suggested? (shrink)

What is the status of a cat in a virtual reality environment? Is it a real object? Or part of a fiction? Virtual realism, as defended by D. J. Chalmers, takes it to be a virtual object that really exists, that has properties and is involved in real events. His preferred specification of virtual realism identifies the cat with a digital object. The project of this paper is to use a comparison between virtual (...) class='Hi'>reality environments and scientific computer simulations to critically engage with Chalmers’s position. I first argue that, if it is sound, his virtual realism should also be applied to objects that figure in scientific computer simulations, e.g. to simulated galaxies. This leads to a slippery slope because it implies an unreasonable proliferation of digital objects. A philosophical analysis of scientific computer simulations suggests an alternative picture: The cat and the galaxies are parts of fictional models for which the computer provides model descriptions. This result motivates a deeper analysis of the way in which Chalmers builds up his realism. I argue that he buys realism too cheap. For instance, he does not really specify what virtual objects are supposed to be. As a result, rhetoric aside, his virtual realism isn’t far from a sort of fictionalism. (shrink)

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.

Motion pictures, from their emergence in the late nineteenth century, have been used in ways that have held in tension a number of competing or seemingly contradictory impulses. Movies can document and reveal physical and social realities, extend perception through time and space, and create audio-visual approximations of subjective perspective and mental states; they can mimic or transform reality, or create new verisimilar or fantastical screen worlds that, in part, resemble, or abstract our own. Over the past 120 (...) years, many thinkers have attempted to define the aesthetic nature of the medium in, at times, prescriptive or overly conditional ways that centre on some technologies (notably the camera), techniques, or types of motion picture making while excluding others (notably animation), and that bracket or narrowly circumscribe the question of viewer experience. However, in the past thirty years or so, we have seen an expanded interest in forms previously more marginalized in film studies, such as documentary, docudrama, and animation. This is due in part to the digital turn in both screen media production and distribution, which has led to the proliferation and pervasiveness of both. We have also seen much deeper consideration of how viewers understand, experience, and think with screen media with the rise of phenomenological and cognitive approaches to the screen-viewer relationship. Carl Plantinga has become a key and productive figure during these years, generating persuasive understandings of the emotional, schematic, and moral dimensions of our experience of screen media, and the ways in which films and TV are designed for such purposes. A cognitivist, he is interested in the possibilities of the screen to allow us to better imagine and empathize with the experiences of others, to persuade us of a state of affairs, and to provoke our capacity for moral reasoning.

Alters the landscape of Lacanian film theory by revealing an "emancipatory drive" in transnational cinema.

The essay aims to examine the concept of digital ekphrasis in virtual reality environments. The emergence of immersive narrative worlds, both in videogames and artistic expression, requires a reflection on the relationships between traditional narrative forms (literature and painting, as well as photography and cinema) and the possibilities that technological development brings to the evolution of artistic and expressive languages. Starting from the analysis of Alejandro González Iñárritu’s virtual reality installation "Carne y Arena", the essay questions (...) the continuity/discontinuity relationship with the semiotic and aesthetic universes conventionally summoned by ekphrasis. The transformation of the medium, which places the viewer immediately within the work, abolishes not only the distance between the involved expressive media, integrating them intermedially, but also the distance between work and spectator, according to a paradigm of aesthetic experience minority within aesthetics, attributable to a theoretical line that combines Merleau-Ponty and Deleuze. The resonance between forms of expressiveness significantly radicalizes the scope of ekphrasis, as visual discourse is no longer transposed to a discursive level, as traditionally occurred, but into other forms of the visual and the sensible that continually set the semiosis of the work in motion.

Dynamic, interactive sports require athletes to identify, pick-up and process relevant information in a very limited time, in order to then make an appropriate response. Perceptual-cognitive skills are, therefore, a key determinant of elite sporting performance. Recently, sport scientists have investigated ways to assess and train perceptual-cognitive skills, with one such method involving the use of blurred stimuli. Here, we describe the two main methods used to generate blur and then review the current findings in a sports context. Overall, it (...) has been shown the use of blur can enhance performance and learning of sporting tasks in novice participants, especially when the blur is applied to peripheral stimuli. However, while intermediate and expert level participants are relatively impervious to the presence of blur, it remains to be determined if they are positive effects on learning. In a final section, we describe some of the methodological issues that limit the application of blur and then discuss the potential use of virtual reality to extend the current research base in sporting contexts.

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.

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)

Hybrid Documentary and Non-Binary Cinema offers an expansive exploration of the contemporary documentary cinema form, aesthetics, and ethics. Beginning with a brief history of early seminal examples of magical realism, and constructed realities in documentary and ethnographic film the book will focus on recent and present-day examples of work that blur the lines between fiction and non-fiction. The book will also take a series of case studies to question the vision and motives of filmmakers working between documentary and fictional film. (...) It will consider the aesthetic and ethical challenges of these works and look toward the future of non-fiction filmmaking after the internet, and in the realm of the metaverse. The book will offer both an entry point to discover new tendencies and a deeper understanding for those readers who are more familiar with the field. Given its interdisciplinary subject nature, the book will appeal to audiences across a spectrum of interests such as film, fine art, anthropology, documentary, sociology and Drama. (shrink)

Projecting Illusion offers a systematic analysis of the impression of reality in the cinema and the pleasure it gives to the film spectator. Film provides a compelling experience that can be considered as a form of illusion akin to the experience of day-dream and dream. Examining the concept of illusion and its relationship to fantasy in the experience of visual representation, Richard Allen situates his explanation within the context of an analytical criticism of contemporary film and critical theory. He (...) argues that many contemporary film theorists correctly identify the significance of the impression of reality, although their explanation of it is incorrect because of an invalid philosophical understanding of the relationship between the mind, representation and reality. Offering a clear presentation and critique of the central arguments of contemporary film and critical theory, Allen also touches on fundamental issues in current discourses of philosophy, art history and feminist theory.

Spatial, physical, and semantic magnitude dimensions can influence action decisions in human cognitive processing and interact with each other. For example, in the SNARC effect, semantic numerical magnitude facilitates left-hand or right-hand responding dependent on the small or large magnitude of number symbols. SNARC-like interactions of numerical magnitudes with the radial spatial dimension (depth) were postulated from early on. Usually, the SNARC effect in any direction is investigated using fronto-parallel computer monitors for presentation of stimuli. In such 2D setups, however, (...) the metaphorical and literal interpretation of the radial depth axis with seemingly close / far stimuli or responses are not distinct. Hence, it is difficult to draw clear conclusions with respect to the contribution of different spatial mappings to the SNARC effect. In order to disentangle the different mappings in a natural way, we studied parametrical interactions between semantic numerical magnitude, horizontal directional responses, and perceptual distance by means of stereoscopic depth in an immersive virtual reality (VR). Two VR experiments show horizontal SNARC effects across all spatial displacements in traditional latency measures and kinematic response parameters. No indications of a SNARC effect along the depth axis, as it would be predicted by a direct mapping account, were observed, but the results show a non-linear relationship between horizontal SNARC slopes and physical distance. Steepest SNARC slopes were observed for digits presented close to the hands. We conclude that spatial-numerical processing is susceptible to effector-based processes but relatively resilient to task-irrelevant variations of radial-spatial magnitudes. (shrink)

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)

Drawing on the critical theories of Jean Baudrillard, Cinema of Simulation performs close readings of key films to examine cinematic visions of mutational reality.

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)
