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)

Much of the excitement about virtual reality and its potential for things like entertainment, art, education, and activism is its ability to generate experiences that are powerfully immersive. However, discussions of VR tend to invoke the notion of immersive experience without subjecting it to closer scrutiny; and discussions often take it for granted that immersive experience is a single unified phenomenon. Against this, we argue that there are four distinct types or aspects of immersive experience (...) that should be distinguished: representational immersion, which corresponds roughly to what is sometimes called “psychological presence”; participatory immersion, which is related to the interactive aspects of VR experience; affective immersion, which has to do with the subject’s emotional relation to the experience; and narrative immersion, which captures the phenomenon of being caught up in the flow of events experienced. We argue that this four-way distinction helps us understand the powerfully immersive character of VR, while also recognizing its continuity with the immersion we experience with media such as novels, films, and music. We also argue that the account of immersion we offer here lets us better understand the connection between VR and empathy, charting a middle course between extreme enthusiasts who view VR as the ultimate “empathy machine” and extreme skeptics who argue that this attitude is misguided.

In this article I examine a recent development in online communication, the immersive virtual worlds of Massively Multiplayer Online Role-Playing Games (MMORPGs). I argue that these environments provide a distinct form of online experience from the experience available through earlier generation forms of online communication such as newsgroups, chat rooms, email and instant messaging. The experience available to participants in MMORPGs is founded on shared activity, while the experience of earlier generation online communication is largely if not wholly dependent (...) on the communication itself. This difference, I argue, makes interaction in immersive virtual worlds such as MMORPGs relevantly similar to interaction in the physical world, and distinguishes both physical world and immersive virtual world interaction from other forms of online communication. I argue that to the extent that shared activity is a core element in the formation of friendships, friendships can form in immersive virtual worlds as they do in the physical world, and that this possibility was unavailable in earlier forms of online interaction. I do, however, note that earlier forms of online interaction are capable of sustaining friendships formed through either physical or immersive virtual world interaction. I conclude that we cannot any longer make a sharp distinction between the physical and the virtual world, as the characteristics of friendship are able to be developed in each. (shrink)

Background: Dementia is one the major problems of aging societies, and, novel and effective non-drug therapies are required as interventions in the oldest-old to prevent cognitive decline.Objective: This study aims to examine the efficacy and safety of reminiscence using immersive virtual reality focusing on anxiety that often appears with cognitive decline. The secondary objective is to reveal the preference for VR image types for reminiscence: live-action or computer graphics.Methods: This was a pilot, open-label, and randomized crossover study which (...) was conducted on January 2020 at a single nursing home. 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)

GoalThis paper presents an immersive Virtual Reality system to analyze and train Executive Functions of soccer players. EFs are important cognitive functions for athletes. They are a relevant quality that distinguishes amateurs from professionals.MethodThe system is based on immersive technology, hence, the user interacts naturally and experiences a training session in a virtual world. The proposed system has a modular design supporting the extension of various so-called game modes. Game modes combine selected game mechanics with specific simulation (...) content to target particular training aspects. The system architecture decouples selection/parameterization and analysis of training sessions via a coaching app from an Unity3D-based VR simulation core. Monitoring of user performance and progress is recorded by a database that sends the necessary feedback to the coaching app for analysis.ResultsThe system is tested for VR-critical performance criteria to reveal the usefulness of a new interaction paradigm in the cognitive training and analysis of EFs. Subjective ratings for overall usability show that the design as VR application enhances the user experience compared to a traditional desktop app; whereas the new, unfamiliar interaction paradigm does not negatively impact the effort for using the application.ConclusionThe system can provide immersive training of EF in a fully virtual environment, eliminating potential distraction. It further provides an easy-to-use analyzes tool to compare user but also an automatic, adaptive training mode. (shrink)

My research into Virtual Reality technology and its central property of immersion has indicated that immersion in Virtual Reality (VR) electronic systems is a significant key to the understanding of contemporary culture as well as considerable aspects of previous culture as detected in the histories of philosophy and the visual arts. The fundamental change in aesthetic perception engendered by immersion, a perception which is connected to the ideal of total-immersion in virtual space, identifies certain shifts in ontology which (...) are relevant to a better understanding of the human being. This understanding was achieved through a broad inquiry into the histories of Virtual Reality, philosophy, and the visual arts and has lead to the formulation of an aesthetic theory of immersive consciousness indicative of immersive culture. The primary subject of this discourse is immersion then: an experience which will be identified within the dissertation as the indispensable characteristic of Virtual Reality. The understanding of immersion arrived at here will be used to fashion a synchronous theory of art particularly informed by encounters and concepts of immersion into virtuality. To sufficiently address this subject in a scholarly fashion, I have researched, found and accumulated aesthetic and philosophic examples of immersive tendencies, as found within the histories of art and philosophy, which subsequently contributed towards the articulation of what I have come to call immersive consciousness. As a result of formulating such an immersive consciousness, a good deal of the basis for the questioning of the Western ontological tradition has been found in the Western tradition itself when we look with new eyes and ask new uncertain questions. Moreover, this immersive consciousness will be used to propose some abstract questions encircling today's electronic-based culture. Through the structuring of the argument within the thesis - and overtly within the conclusion - I have articulated a non-teleological creative strategy which provides the basis for an unconstraining integration of noologies (ways of semblancing the thinking process). This strategy provides a means of exemplifying - and for honoring - various methods of thinking. This structuring strategy is consistent with the 'hacker ethic' as defined by Steven Levy, as a demand that access to computers - and anything which might teach us something about the way the world works - should be unlimited and total. To follow this strategy, this dissertation has set out to understand how topical conceptions of virtual immersion connect to pre-existing systems of thought as revealed in art as they have extended out of antecedent ontological self-understandings, historical human self-understandings which have evidenced themselves in the elaboration of technological objectives. To do this I have forged a certain rhizomatic paternity/maternity for Virtual Reality within this dissertation by joining choice immersive examples of simulacra technology into mental connections with the relevant examples culled from the histories of art, architecture, information-technology, sex, myth, space, consciousness and philosophy.

The integration of virtual reality into STEM education has generated growing interest in how this technology impacts the understanding and application of scientific concepts. This study focuses on investigating this relationship by using the MICMAC technique to identify key variables and their interactions in virtual educational environments. It was found that variables such as the design of educational content, the quality of the virtual experience, and the interactivity of the environment are key to the learning process in STEM. In (...) addition, determinant and autonomous variables were identified, which play fundamental roles in the generation of scientific knowledge for students. These results highlight the relevance of considering various aspects of virtual educational design to improve the effectiveness of learning in STEM. The practical implications of this study are significant for educators and educational program designers, highlighting the need to create immersive, interactive, and collaborative virtual environments to promote better understanding and application of scientific concepts. This study contributes to existing knowledge by providing a deeper understanding of how virtual reality can enhance learning in STEM, and suggests directions for future research in the field.

Globalization and informatization are reshaping human life and social behaviors. The purpose is to explore the worldwide strategies to cultivate international talents with a global vision. As a global language with the largest population, English, and especially its learning effect, have always been the major concerns of scholars and educators. This work innovatively studies the combination of immersion-based English teaching with virtual reality technology. Then, based on the experimental design mode, 106 students from a Chinese school were selected for (...) a quasi-experimental study for 16 weeks. The collected data were analyzed by computer statistical software, and hypotheses are verified. The results showed that there is a significantly positive correlation between VR and immersion-based language teaching. There is a significantly positive correlation between immersion-based language teaching and academic achievement, and VR is positively correlated with learning outcome. Compared with other state-of-art research methods, this work modifies the students’ oral test through the analysis and comparison with the system database, and the students’ learning effect is greatly improved. Finally, some suggestions are put forward according to the research results to provide an experimental reference for English teachers and future linguistics teaching. (shrink)

Natural scientists working at the intersection of virtual reality, psychology, and computer science have recently explored the question of whether Embodied Virtual Reality (EVR) can be employed to train empathy. While for some authors (e.g., Bertrand et el. 2018), EVR can enhance empathy by means of creating a series of perceptual illusions, which lead users to adopt the other’s perspective and resonate with her experience, other authors (e.g., Sora-Domenjó 2022; Sutherland 2016) have been more skeptical about the powers (...) of EVR to increase empathy in its users. This chapter aims at contributing to this recent debate by exploring how perspective-taking contributes to empathy in EVR. After an analysis of perspective-taking in non-virtual and virtual environments, the chapter introduces the distinction between sensual and emotional empathy found in classical and contemporary phenomenology (Stein 1989 ; Sveaneus 2018). While in sensual empathy, the user empathizes with the other’s lived body, in emotional empathy, she apprehends the other’s emotional states and their related values. It is argued that while the perceptual illusions elicited by EVR can lead the user to the impression of a body swap and, in so doing, foster sensual empathy, for the apprehension of the other’s emotions, which is crucial to emotional empathy, EVR must be supplemented with a series of narrative devices which that make the other’s emotions and values accessible to her.

Mathematics is an important foundation for the development of science education. In the past, when instructors taught mathematical concepts of geometry shapes, they usually used traditional textbooks and aids to conduct teaching activities, which resulted in students not being able to understand the principles completely. Nowadays, it has become a trend to integrate emerging technologies into mathematics courses and to use digital instructional aids. Emerging technologies can effectively enhance students’ sensory experience while strengthening their impressions and understandings of subject concepts. (...) In this paper, we apply virtual reality immersive technologies to develop a “virtual reality immersive learning mathematics geometry system,” which is used to teach mathematical geometry concepts. Teachers use the system to develop three basic mathematical geometry learning materials: “Triangular pyramid volume = 1/3 prism volume,” “Cone volume calculation,” and “Triangle center of gravity derivation.” In the experimental activity, the teacher uses virtual reality teaching aids to guide students to learn mathematical geometry concepts in a fun way so that they can achieve the effectiveness of immersive learning. This study explores the impact of using the virtual reality immersive learning mathematics geometry system on students’ technology acceptance, learning motivations, and learning performance. The experimental result showed that using the virtual reality immersive learning mathematics geometry system can improve the learning motivation and learning performance of students. The findings indicated that the experimental group had better learning outcomes after completing the learning tasks of three geometric units. The experimental group used the virtual reality immersive learning mathematics geometry system which can lead to better learning outcomes. According to the ARCS questionnaire, students in the experimental group were confident to understand new subjects. At the same time, the mode of completing the game can effectively give students a sense of accomplishment. The use of emerging technologies in the classroom can be an attractive learning mode for students. (shrink)

BackgroundEven though virtual reality is more and more considered for its power of distraction in different medical contexts, the optimal conditions for its use still have to be determined in order to design interfaces adapted to therapeutic support in oncology.ObjectiveThe objective of this study was to examine the benefits of VR using two immersion methods and comparing them with each other in a population of women with breast cancer who have undergone breast surgery, during scar massage sessions.MethodsIn a physiotherapy (...) center, each patient participated in four experimental conditions in a random order: two sessions used virtual immersion, one session proposed musical listening and the fourth one was a standard session care. The impact of the level of patient involvement in the virtual world was apprehended through the evaluation of the feeling of presence; the estimation of elapsed time of the physiotherapy sessions and particular attention was paid to the evaluation of patient emotional state.ResultsOur study showed an increase in positive emotions and a decrease in anxiety regardless which support methods were offered. Participatory VR created a feeling of more intense spatial presence.ConclusionOur results highlight the importance of the context in which VR should be offered. The presence of the practitioner and his interactions with the patient can provide a context just as favorable in reducing anxiety as the emotional regulation tools used. The use of technological tools should be favored when the practitioner is unavailable during the treatment phase or, even, in order to reduce the monotonous nature of repetitive therapeutic sessions.

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.

This article criticises David Chalmers’ ‘Reality+’ by interrogating its distinction of virtual reality (VR) from 2D, non-VR video games, a distinction made on the grounds that VR is immersive and these types of video games are not because immersion is a distinct characteristic of 3D perceptually represented VR. Building on the Balcerak Jacksons’ account of ‘representational immersion’, which they acknowledge has ‘perceptual’ and ‘non-perceptual’ elements, I develop an account of ‘non-perceptual representational immersion’ and use it to critique (...) Chalmers’ treatment of VR, immersion, and video games, indirectly problematizing his central ontological claim that ‘virtual reality is genuine reality’ and the reflections he makes about future society which rest upon it. I argue that video games are rich in non-perceptual representational immersion, which includes the representation of non-perceptual information about the structure and behaviour of a virtual world and its systems, the non-perceptual cognitive states that are generated in the player by the virtual world, and the immersion which comes from the constitutively cognitive nature of the player’s engagement with the virtual world, a cognitive engagement construed in an enactive sense. These are just as crucial to the phenomenon of digital immersion as perception. Immersion generally is a much more complicated phenomenon than Chalmers allows for, and it is better conceived as taking place on a spectrum which includes both 3D and 2D experiences of virtual worlds, not as hinging on 3D perceptual representation. I use ‘immersive simulation’ games as a case study. (shrink)

Although the importance of the concept of immersion in game studies is indisputable, its meaning remains imprecise and ambiguous. My goal here is to develop a phenomenological clarification of this concept. I begin by clarifying how immersion has been understood in game studies. I further contend that immersion in digital games should be recognized as one modality of immersion among others. This basic realization allows one to open a dialogue between game studies and phenomenology. I develop a phenomenological conception of (...) immersion, which relies on Alfred Schutz’s phenomenology of multiple realities and Theodor Conrad’s phenomenology of immersion. Although such an approach provides us with a general conception of immersion, it does not clarify what specific features characterize immersion in digital games. I argue that this form of immersion is a hybrid phenomenon, which shares certain features with immersion in non-digital games and other features with immersion in other types of digital media. I further demonstrate that immersion in digital games is characterized by a specific function of embodiment. With this in mind, I conclude my analysis by introducing a phenomenologically grounded distinction between actual and virtual embodiment, thereby clarifying in which sense immersion in digital games is an embodied and a disembodied experience.

BackgroundExercise is one of the effective ways to improve cognition. Different forms of exercises, such as aerobic exercise, resistance exercise, and coordination exercise, have different effects on the improvement of cognitive impairment. In recent years, exergames based on Non-Immersive Virtual Reality have been widely used in entertainment and have gradually been applied to clinical rehabilitation. However, the mechanism of NIVR-Exergames on improving motor cognition has not been clarified. Therefore, the aim of this study is to find whether NIVR-Exergames (...) result in a better neural response mechanism to improve the area of the cerebral cortex related to motor cognition under functional near-infrared spectroscopy dynamic monitoring in comparison with resistance exercise.MethodsA cross-over study design was adopted in this study, and 15 healthy young subjects were randomly divided into group A and group B according to a computerized digital table method. Task 1 was an NIVR-Exergame task, and Task 2 was resistance band stretching. Group A first performed Task 1, rested for 30 min, and then performed Task 2. Group B had the reverse order. The fNIRS test was synchronized in real time during exercise tasks, and heart rate measurements, blood pressure measurements, and 2-back task synchronization fNIRS tests were performed at baseline, Post-task 1, and Post-task 2. The primary outcomes were beta values from the general linear model in different regions of interest, and the secondary outcomes were heart rate, blood pressure, reaction time of 2-back, and accuracy rate of 2-back.ResultsThe activation differences of Task 1 and Task 2 in the right premotor cortex and the left PMC were statistically significant. There were statistically significant differences in the activation of the right supplementary motor area, left dorsolateral prefrontal cortex, left and right PMC between baseline and Post-task 1. The differences in systolic pressure between the two groups at three time points among women were statistically significant.ConclusionIn this study, we found that NIVR-Exergames combined with motor and challenging cognitive tasks can promote the activation of SMA, PMC and DLPFC in healthy young people compared with resistance exercise alone, providing compelling preliminary evidence of the power for the rehabilitation of motor and cognitive function in patients with central nervous system diseases.

To offer engaging neurorehabilitation training to neurologic patients, motor tasks are often visualized in virtual reality. Recently introduced head-mounted displays allow to realistically mimic the body of the user from a first-person perspective in a highly immersive VR environment. In this immersive environment, users may embody avatars with different body characteristics. Importantly, body characteristics impact how people perform actions. Therefore, alternating body perceptions using immersive VR may be a powerful tool to promote motor activity in neurologic (...) patients. However, the ability of the brain to adapt motor commands based on a perceived modified reality has not yet been fully explored. To fill this gap, we “tricked the brain” using immersive VR and investigated if multisensory feedback modulating the physical properties of an embodied avatar influences motor brain networks and control. Ten healthy participants were immersed in a virtual environment using an HMD, where they saw an avatar from first-person perspective. We slowly transformed the surface of the avatar from human to stone. We enforced this visual change by repetitively touching the real arm of the participant and the arm of the avatar with a hammer, while progressively replacing the sound of the hammer against skin with stone hitting sound via loudspeaker. We applied single-pulse transcranial magnetic simulation to evaluate changes in motor cortical excitability associated with the illusion. Further, to investigate if the “stone illusion” affected motor control, participants performed a reaching task with the human and stone avatar. Questionnaires assessed the subjectively reported strength of embodiment and illusion. Our results show that participants experienced the “stone arm illusion.” Particularly, they rated their arm as heavier, colder, stiffer, and more insensitive when immersed with the stone than human avatar, without the illusion affecting their experienced feeling of body ownership. Further, the reported illusion strength was associated with enhanced motor cortical excitability and faster movement initiations, indicating that participants may have physically mirrored and compensated for the embodied body characteristics of the stone avatar. Together, immersive VR has the potential to influence motor brain networks by subtly modifying the perception of reality, opening new perspectives for the motor recovery of patients. (shrink)

Objective: Gait adaptation to environmental challenges is fundamental for independent and safe community ambulation. The possibility of precisely studying gait modulation using standardized protocols of gait analysis closely resembling everyday life scenarios is still an unmet need.Methods: We have developed a fully-immersive virtual reality environment where subjects have to adjust their walking pattern to avoid collision with a virtual agent crossing their gait trajectory. We collected kinematic data of 12 healthy young subjects walking in real world and in (...) the VR environment, both with and without the VA perturbation. The VR environment closely resembled the RW scenario of the gait laboratory. To ensure standardization of the obstacle presentation the starting time speed and trajectory of the VA were defined using the kinematics of the participant as detected online during each walking trial.Results: We did not observe kinematic differences between walking in RW and VR/A-, suggesting that our VR environment per se might not induce significant changes in the locomotor pattern. When facing the VA all subjects consistently reduced stride length and velocity while increasing stride duration. Trunk inclination and mediolateral trajectory deviation also facilitated avoidance of the obstacle.Conclusions: This proof-of-concept study shows that our VR/A+ paradigm effectively induced a timely gait modulation in a standardized immersive and realistic scenario. This protocol could be a powerful research tool to study gait modulation and its derangements in relation to aging and clinical conditions. (shrink)

Virtual reality allows the user to be immersed in environments in which they can experience situations and social interactions from different perspectives by means of virtual embodiment. In the context of rehabilitation of violent behaviors, a participant could experience a virtual violent confrontation from different perspectives, including that of the victim and bystanders. This approach and other virtual scenes can be used as a useful tool for the rehabilitation of intimate partner violence perpetrators, through improvement of their empathic skills (...) or for training in non-violent responses. In this perspective, we revise and discuss the use of this tool in a prison environment for the rehabilitation of IPV perpetrators with a particular focus on practical aspects based on our experience.

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)

Practices such as mindfulness, introspection, and self-reflection are known to have positive short and long-term effects on health and well-being. However, in today's modern, fast-paced, technological world tempted by distractions these practices are often hard to access and relate to a broader audience. Consequently, technologies have emerged that mediate personal experiences, which is reflected in the high number of available applications designed to elicit positive changes. These technologies elicit positive changes by bringing users' attention to the self—from technologies that show (...) representation of quantified personal data, to technologies that provide experiences that guide the user closer in understanding the self. However, while many designs available today are either built to support or are informed by these aforementioned practices, the question remains: how can we most effectively employ different design elements and interaction strategies to support positive change? Moreover, what types of input and output modalities contribute to eliciting positive states? To address these questions, we present here a state of the art scoping review of immersive interactive technologies that serve in a role of a mediator for positive change in users. We performed a literature search using ACM Digital Library, Web of Science, IEEE Xplore, and Design and Applied Arts Index (beginning of literature—January 1, 2018). We retrieved English-language articles for review, and we searched for published and unpublished studies. Risk of bias was assessed with Downs and Black 26-item QAT scale. We included 34 articles as relevant to the literature, and the analysis of the articles resulted in 38 instances of 33 immersive, interactive experiences relating to positive human functioning. Our contribution is three-fold: First we provide a scoping review of immersive interactive technologies for positive change; Second, we propose both a framework for future designs of positive interactive technologies and design consideration informed by the comparative analysis of the designs; Third, we provide design considerations for immersive, interactive technologies to elicit positive states and support positive change.

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)

[Interactive and Immersive Practices; Critical Spatial Practices. The Augmented Reality of the Exhibition Space] The rise of installations, as well as immersive and interactive spaces, in both art and science museums has accustomed the public to heightened interactivity, leading to a better understanding of social, natural and scientific phenomena.

In recent years, prevalent global societal issues related to fake news, fakery, misinformation, and disinformation were brought to the fore, leading to the construction of descriptive labels such as “post-truth” to refer to the supposedly new emerging era. Thereby, the (mis-)use of technologies such as AI and VR has been argued to potentially fuel this new loss of “ground-truth”, for instance, via the ethically relevant deepfakes phenomena and the creation of realistic fake worlds, presumably undermining experiential veracity. Indeed, _unethical_ and (...) malicious actors could harness tools at the intersection of AI and VR (AIVR) to craft what we call _immersive falsehood_, fake immersive reality landscapes deliberately constructed for malicious ends. This short paper analyzes the ethically relevant nature of the background against which such malicious designs in AIVR could exacerbate the intentional proliferation of deceptions and falsities. We offer a reappraisal expounding that while immersive falsehood could manipulate and severely jeopardize the inherently affective constructions of social reality and considerably complicate falsification processes, humans may neither inhabit a post-truth nor a post-falsification age. Finally, we provide incentives for future AIVR safety work, ideally contributing to a future era of _technology-augmented critical thinking_. (shrink)

IntroductionCognition generally declines gradually over time due to progressive degeneration of the brain, leading to dementia and eventual loss of independent functions. The rate of regression varies among the six cognitive domains. Current modality of cognitive assessment using neuropsychological paper-and-pencil screening tools for cognitive impairment such as the Montreal Cognitive Assessment has limitations and is influenced by age. Virtual reality is considered as a potential alternative tool to assess cognition. A novel, fully immersive automated VR system has been (...) developed to assess the six cognitive domains. As cognition is associated with age, VR performance is postulated to vary with age using this system.AimsThis is a feasibility study to evaluate the VR performance of cognitively healthy adults aged between 35 and 74 years old, based on the performance score and completion time using the CAVIRE system.MethodsConducted in a public primary care clinic in Singapore, 25 multi-ethnic Asian adults were recruited in each of the four age groups in years: 35–44; 45–54; 55–64, and 65–74. The eligibility criteria included a MoCA score of 26 or higher to reflect normal cognition and understanding English instructions. They completed common daily activities ranging from brushing teething to shopping, across 13 VR segments. Their performances scores and completion time were automatically computed by the CAVIRE system. These VR performance indices were compared across the four age groups using one-way ANOVA, F-test of the hypothesis, followed by pair-wise comparisons in the event of a significant F-test.ResultsOne participant dropped out from Group 1. The demographic characteristics of 99 participants were similar across the 4 age groups. Overall, younger participants in Groups 1 and 2 attained higher VR performance scores and shorter completion time, compared to those in Groups 3 and 4, in all six cognitive domains.ConclusionThe CAVIRE VR performance scores and completion time significantly differ between the younger and older Asian participants with normal cognition. Enhancements to the system are needed to establish the age-group specific normal performance indices. (shrink)

Sense of presence and extraneous cognitive load are the two psychological effects widely employed to explain the cognitive outcomes caused by high-immersive media. This study identified the concepts of both technological affordance and the psychological effects of VR learning. It investigated the mechanism by which immersion leads to better or worse communication in the context of art education. We operationalized the concept of immersion into two levels: a high-immersive VR system and a low-immersive tablet system. Through a (...) between-subject experiment, we found that higher immersion not only led to a greater sense of presence but also lowered extraneous cognitive load. Enjoyment and attention increased as a sense of presence rose but were not necessarily predicted by extraneous cognitive load. This study found that sense of presence was a more robust explanatory variable than ECL and that cognitive load could be lower in a high-immersive environment with content specifically designed for VR.

The paper concludes with guidelines for ethical research and rehabilitation using this innovative technology.

Post-stroke depression is a serious complication of stroke that significantly restricts rehabilitation. The use of immersive virtual reality for stroke survivors is promising. Herein, we investigated the effects of a novel immersive virtual reality training system on PSD and explored induced effective connectivity alterations in emotional networks using multivariate Granger causality analysis. Forty-four patients with PSD were equally allocated into an immersive-virtual reality group and a control group. In addition to their usual rehabilitation treatments, (...) the participants in the immersive-virtual reality group participated in an immersive-virtual reality rehabilitation program, while the patients in the control group received 2D virtual reality rehabilitation training. The Hamilton Depression Rating Scale, modified Barthel Index, and resting-state functional magnetic resonance imaging data were collected before and after a 4-week intervention. rsfMRI data were analyzed using multivariate GCA. We found that the immersive virtual reality training was more effective in improving depression in patients with PSD but had no statistically significant improvement in MBI scores compared to the control group. The GCA showed that the following causal connectivities were strengthened after immersive virtual reality training: from the amygdala, insula, middle temporal gyrus, and caudate nucleus to the dorsolateral prefrontal cortex; from the insula to the medial prefrontal cortex; and from the thalamus to the posterior superior temporal sulcus. These causal connectivities were weakened after treatment in the control group. Our results indicated the neurotherapeutic use of immersive virtual reality rehabilitation as an effective non-pharmacological intervention for PSD; the alteration of causal connectivity in emotional networks might constitute the neural mechanisms underlying immersive-virtual reality rehabilitation in PSD.

The phenomenon of immersion mainly appears and relates to human existence in the interactive electronic environment. Immersion can produce an experience of electronically generated reality, which consists of feelings similar to those known from the experience of the physical world and can influence our sensuous and intentional attitude. A person enters the electronic world, frequently finding there the value of being and a sphere for her/his own activity, which can release personality and produce the kind of emotional attitude which (...) sometimes possibly does not appear in the physical world. Immersion was also described in electronic interactive art as a phenomenon which operates on the basis of aesthetic experience, where it is connected with feelings of being surrounded by outside influences, or with the “absorption” of perceiver by the work of art. The description of immersion on the basis of interactive artbecame the foundation for treating it as a general feature of art and also makes it possible to treat art as an immersive environment, where immersion becomes a historical notion, shaped by the historical development.

In his extremely suggestive essay entitled 'Towards an Immersive Intelligence', artist and theorist Joseph Nechvatal defines immersive virtual reality art as 'an art that has a continuous, coherent quality and strives to ambiently include everything of perceptual worth within its domain in an overall, enveloping totality that is concerted and without an evident frame or border'1. Television, on the face of it, is not a medium capable of providing any form of sensory immersion: compared to the Imax (...) or to a trip through virtual reality goggles, its screen (even in its 'giant' sizes) remains ridiculously small. More importantly, whereas immersion requires the intense capture of our full attention in the enveloping totality it artificially creates, our viewing of television is generally distracted and superficial.

As digital and immersive architectural installations and augmented reality applications generate new sensations, new digital dimensions and boundaries create new perceptions of our built environment. Digital architectural installations as immersive environments make data visible and tangible and give access to data as an experiential flow. Like the works of Refik Anadol, TeamLab or Universal Everything, digital architectural installations point to a neuroarchitectural and neurophenomenological atmosphere that refers to the understanding and measurement of embodied human experience, and how (...) spaces affect people and how they behave in a given setting. The objectivity of the screen allows viewers to observe through screens, and the screen as an ambivalent object provides a physical interface that transcends the shadow of its materiality, transforming the viewer’s environmental perception. Therefore, this article examines digital architectural environments that reveal the boundaries of architectural space, with particular consideration given to neuroaesthetics. In these data-driven environments, the human body is at the centre of multimodal perception. Therefore, these environments open the door to understanding the boundaries of architecture and invite the viewers to explore the boundaries of art and architecture that have become a fusion in the digital environment.

Covid-19 has prompted a surge of data visualizations that have been published for public consumption, yet, many have not had broad appeal or may have not been well-understood by laypeople. A data storytelling platform called Flow Immersive has been created to successfully engage both laypeople and experts in understanding complex information. This tool integrates emerging technologies [e.g., augmented reality and virtual reality ] with a multiplatform, multiuser publishing approach. From October 2020 to December 2020, Flow’s Covid-19 AR (...) videos captured 9 million views, and have been used in multiple professional presentations. This paper documents the journey from development to deployment, and some user feedback which all led to breakthroughs in scalability and higher levels of engagement. (shrink)

Brain–machine interfaces combining visual, auditory, and tactile feedback have been previously used to generate embodiment experiences during spinal cord injury rehabilitation. It is not known if adding temperature to these modalities can result in discomfort with embodiment experiences. Here, comfort levels with the embodiment experiences were investigated in an intervention that required a chronic pain SCI patient to generate lower limb motor imagery commands in an immersive environment combining visual, auditory, tactile, and thermal feedback. Assessments were made pre-/ post-, (...) throughout the intervention, and at 7 weeks follow up. Overall, high levels of embodiment in the adapted three-domain scale of embodiment were found throughout the sessions. No significant adverse effects of VR were reported. Although sessions induced only a modest reduction in pain levels, an overall reduction occurred in all pain scales at follow up. A high degree of comfort in the comfort scale for the thermal-tactile sleeve, in both the thermal and tactile feedback components of the sleeve was reported. This study supports the feasibility of combining multimodal stimulation involving visual, auditory, tactile, and thermal feedback to generate embodiment experiences in neurorehabilitation programs.

Cinematic virtual reality (CVR) offers filmmakers a wide range of possibilities to explore new techniques regarding movie scripting, shooting and editing. Despite the many experiments performed so far both with both live action and computer-generated movies, just a few studies focused on analyzing how the various techniques actually affect the viewers’ experience. Like in traditional cinema, a key step for CVR screenwriters and directors is to choose from which perspective the viewers will see the scene, the so-called point of (...) view (POV). The aim of this paper is to understand to what extent watching an immersive movie from a specific POV could impact the narrative engagement (NE), i.e., the viewers’ sensation of being immersed in the movie environment and being connected with its characters and story. Two POVs that are typically used in CVR, i.e., first-person perspective (1-PP) and external perspective (EP), are investigated through a user study in which both objective and subjective metrics were collected. The user study was carried out by leveraging two live action 360° short films with distinct scripts. The results suggest that the 1-PP experience could be more pleasant than the EP one in terms of overall NE and narrative presence, or even for all the NE dimensions if the potential of that POV is specifically exploited.
