This article explores digital material/ism by examining student teachers’ experiences, processes and products with fully immersive virtual reality (VR) as part of visual art education. The students created and painted a virtual world, given the name Gretan puutarha (‘Greta’s Garden’), using the Google application Tilt Brush. They also applied photogrammetry techniques to scan 3D objects from the real world in order to create 3D models for their VR world. Additionally, they imported 2D photographs and drawings along with applied animated effects to construct their VR world digitally, thereby remixing elements from real life and fantasy. The students were asked open-ended questions to find out how they created art virtually and the results were analysed using Burdea’s VR concepts of immersion, interaction and imagination. Digital material was created intersubjectively and intermedially while it was also remixed with real and imaginary. Various webs of meanings were created, both intertextual and rhizomatic in nature.

Before And After

Abstract Tridimensional (3D) rendering of volumetric neuroimaging is increasingly been used to assist surgical management of brain tumors. New technologies allowing immersive virtual reality (VR) visualization of obtained models offer the opportunity to appreciate neuroanatomical details and spatial relationship between the tumor and normal neuroanatomical structures to a level never seen before. We present our preliminary experience with the Surgical Theatre, a commercially available 3D VR system, in 60 consecutive neurosurgical oncology cases. 3D models were developed from volumetric CT scans and MR standard and advanced sequences. The system allows the loading of 6 different layers at the same time, with the possibility to modulate opacity and threshold in real time. Use of the 3D VR was used during preoperative planning allowing a better definition of surgical strategy. A tailored craniotomy and brain dissection can be simulated in advanced and precisely performed in the OR, connecting the system to intraoperative neuronavigation. Smaller blood vessels are generally not included in the 3D rendering, however, real-time intraoperative threshold modulation of the 3D model assisted in their identification improving surgical confidence and safety during the procedure. VR was also used offline, both before and after surgery, in the setting of case discussion within the neurosurgical team and during MDT discussion. Finally, 3D VR was used during informed consent, improving communication with families and young patients. 3D VR allows to tailor surgical strategies to the single patient, contributing to procedural safety and efficacy and to the global improvement of neurosurgical oncology care.

Thanks to their playful and educational approach Virtual Museum systems are very effective for the communication of Cultural Heritage. Among the latest technologies Immersive Virtual Reality is probably the most appealing and potentially effective to serve this purpose; nevertheless, due to a poor user-system interaction, caused by an incomplete maturity of a specific technology for museum applications, it is still quite uncommon to find immersive installations in museums.<br> This paper explore the possibilities offered by this technology and presents a workflow that, starting from digital documentation, makes possible an interaction with archaeological finds or any other cultural heritage inside different kinds of immersive virtual reality spaces.<br> Two different cases studies are presented: the National Archaeological Museum of Marche in Ancona and the 3D reconstruction of the Roman Forum of Fanum Fortunae. Two different approaches not only conceptually but also in contents; while the Archaeological Museum is represented in the application simply using spherical panoramas to give the perception of the third dimension, the Roman Forum is a 3D model that allows visitors to move in the virtual space as in the real one.<br> In both cases, the acquisition phase of the artefacts is central; artefacts are digitized with the photogrammetric technique Structure for Motion then they are integrated inside the immersive virtual space using a PC with a HTC Vive system that allows the user to interact with the 3D models turning the manipulation of objects into a fun and exciting experience.<br> The challenge, taking advantage of the latest opportunities made available by photogrammetry and ICT, is to enrich visitors’ experience in Real Museum making possible the interaction with perishable, damaged or lost objects and the public access to inaccessible or no longer existing places promoting in this way the preservation of fragile sites.

L2 Learning

Learning a second language (L2) presents a significant challenge to many people in adulthood. Platforms for effective L2 instruction have been developed in both academia and the industry. While real-life (RL) immersion is often lauded as a particularly effective L2 learning platform, little is known about the features of immersive contexts that contribute to the L2 learning process. Immersive virtual reality (iVR) offers a flexible platform to simulate an RL immersive learning situation, while allowing the researcher to have tight experimental control for stimulus delivery and learner interaction with the environment. Using a mixed counterbalanced design, the current study examines individual differences in L2 performance during learning of 60 Mandarin Chinese words across two learning sessions, with each participant learning 30 words in iVR and 30 words via word–word (WW) paired association. Behavioral performance was collected immediately after L2 learning via an alternative forced-choice recognition task. Our results indicate a main effect of L2 learning context, such that accuracy on trials learned via iVR was significantly higher as compared to trials learned in the WW condition. These effects are reflected especially in the differential effects of learning contexts, in that less successful learners show a significant benefit of iVR instruction as compared to WW, whereas successful learners do not show a significant benefit of either learning condition. Our findings have broad implications for L2 education, particularly for those who struggle in learning an L2.

Virtual Tourism

Purpose. The study attempts to define virtual reality in tourism as well as to characterise and present chosen applications created for the purposes of virtual sightseeing. Based on the survey conducted among tourism and recreation students of the Jerzy Kukuczka Academy of Physical Education in Katowice, the study attempts to answer the provocative question: “can virtual tourism replace real-world travel?”, and to analyse participants’ opinions on the topic of virtual trips. Methods. Analysis of scientific studies as well as information and data on the possibility of using immersive virtual reality in human life with particular consideration given to tourism. An overview of applications enabling taking trips through immersive exploration of virtual environments. The survey was conducted among AWF students. Participants expressed their opinions about virtual sightseeing. Findings. Virtual reality is increasingly used in various fields of human life. It is entering the world of tourism, in which it is used to create presentations of hotels and resorts, and to promote towns and tourist facilities. Appropriate software and IT equipment allow to take deliberate, planned and very realistic virtual trips. The authors of the work defined such tourism as all activities carried out by persons who immerse themselves in virtual reality for learning and entertainment purposes in order to experience the illusion of change of their everyday, real surroundings in time and space. Tourism understood in such a way allows us not only to go to almost any place without the necessity of leaving home. It also allows for visiting areas and objects which cannot be explored in real life. It enables a visitor, among others, to travel in space and visit historical sites which no longer exist in their original form, but have been recreated in computer applications. Virtual tourism also allows for exploring fictional locations created by designers of photorealistic graphics as well as valuable and sensitive monuments, and taking trips to places which are dangerous or prohibited. In the conducted survey, it has been concluded that even though tourism and recreation students found experience with virtual reality to be positive, the majority is not convinced that this form of tourism can replace real-world travel. Research and conclusions limitations. There are only a few publications concerning immersive virtual reality travel experience. Access to the software was quite early. Practical implications. Understanding and reorganisation of issues related to immersive virtual reality travel experience. The study may constitute an original introduction and encouragement to carry out qualitative and quantitative research on newly created virtual tourism. Originality. An original concept of understanding virtual tourism was presented. Type of paper. Empirical research and review.

Clear Objective

The objective of this study was to use virtual reality as a validation method of a new multimodal warning for use in situations of risk and danger. This warning is intended to be more efficient than the static warnings as regards their ability to convey clear, objective information and securely. The virtual environment used was developed with immersive virtual reality simulating a risk and danger to the user. This virtual environment allows situations are simulated in real life would be impossible for putting at risk the lives of people. For the warning efficiency were evaluated, we used two warnings, static and multimodal, which consisted of harmonization between the ISO and ANSI standards. As innovation factor used was the explanation of the consequences of non-compliance. Multimodal elements used in the notice were a file with a recorded human voice and a flashing red light. These results demonstrated that the virtual environment used, and the multimodal warning were efficient in their goals. The results of the variables used were positive and the hypotheses was validated with the use of statistical tests.

Because most real-life foreign language speech is naturally unpredictable, spontaneous speech should be practiced in the foreign language classroom. Student teachers of English as a foreign language (EFL) may benefit from practising methodology for spontaneous speech practice. This article reports the findings for a study into EFL student teachers’ experiences with using improvisation activities, exploring the relevance of improvisation activities for spontaneous speech practice. The data include semi-guided texts and reluctant speakers’ interviews. The findings showed that improvisation activities facilitated spontaneous speech practice and strengthened speaking confidence through enjoyment. The ‘spontaneous speech mindset’ enabled participants to explore linguistic and creative boundaries. The study showed that application of improvisation activities is an excellent method for spontaneous speech practice in EFL teacher education.

Active Research

Developing a seamless merging of real and virtual image streams and 3D models is an active research topic in augmented reality (AR). We propose a method for real-time augmentation of real videos with 2D and 3D objects by addressing the occlusion issue in an unique fashion. For virtual planar objects (such as images), the 2D overlay is automatically overlaid in a planar region selected by the user in the video. The overlay is robust to arbitrary camera motion. Furthermore, a unique background-foreground segmentation algorithm renders this augmented overlay as part of the background if it coincides with foreground objects in the video stream, giving the impression that it is occluded by foreground objects. The proposed technique does not require multiple cameras, camera calibration, use of fiducials, or a structural model of the scene to work. Extending the work further, we propose a novel method of augmentation by using trifocal tensors to augment 3D objects in 3D scenes to similar effect and implement it in real time as a proof of concept. We show several results of the successful working of our algorithm in real-life situations. The technique works on a real-time video from a USB camera, Creative Webcam III, onaPIV1.6GHz system without any special hardware support.

Abstract Purpose Three-dimensional (3D) surgical planning is widely accepted in liver surgery. Currently, the 3D reconstructions are usually presented as 3D PDF data on regular monitors. 3D-printed liver models are sometimes used for education and planning. Methods We developed an immersive virtual reality (VR) application that enables the presentation of preoperative 3D models. The 3D reconstructions are exported as STL files and easily imported into the application, which creates the virtual model automatically. The presentation is possible in “OpenVR”-ready VR headsets. To interact with the 3D liver model, VR controllers are used. Scaling is possible, as well as changing the opacity from invisible over transparent to fully opaque. In addition, the surgeon can draw potential resection lines on the surface of the liver. All these functions can be used in a single or multi-user mode. Results Five highly experienced HPB surgeons of our department evaluated the VR application after using it for the very first time and considered it helpful according to the “System Usability Scale” (SUS) with a score of 76.6%. Especially with the subitem “necessary learning effort,” it was shown that the application is easy to use. Conclusion We introduce an immersive, interactive presentation of medical volume data for preoperative 3D liver surgery planning. The application is easy to use and may have advantages over 3D PDF and 3D print in preoperative liver surgery planning. Prospective trials are needed to evaluate the optimal presentation mode of 3D liver models.

Objective: The assessment of cognitive functions such as prospective memory, episodic memory, attention, and executive functions benefits from an ecologically valid approach to better understand how performance outcomes generalize to everyday life. Immersive virtual reality (VR) is considered capable of simulating real-life situations to enhance ecological validity. The present study attempted to validate the Virtual Reality Everyday Assessment Lab (VR-EAL), an immersive VR neuropsychological battery, against an extensive paper-and-pencil neuropsychological battery. Methods: Forty-one participants (21 females) were recruited: 18 gamers and 23 non-gamers who attended both an immersive VR and a paper-and-pencil testing session. Bayesian Pearson correlation analyses were conducted to assess construct and convergent validity of the VR-EAL. Bayesian t-tests were performed to compare VR and paper-and-pencil testing in terms of administration time, similarity to real life tasks (i.e., ecological validity), and pleasantness. Results: VR-EAL scores were significantly correlated with their equivalent scores on the paper-and-pencil tests. The participants’ reports indicated that the VR-EAL tasks were significantly more ecologically valid and pleasant than the paper-and-pencil neuropsychological battery. The VR-EAL battery also had a shorter administration time. Conclusion: The VR-EAL appears as an effective neuropsychological tool for the assessment of everyday cognitive functions, which has enhanced ecological validity, a highly pleasant testing experience, and does not induce cybersickness.

Somatosensory Stimuli

AbstractEmbodying an artificial agent through immersive virtual reality (IVR) may lead to feeling vicariously somatosensory stimuli on one’s body which are in fact never delivered. To explore whether vicarious touch in IVR reflects the basic individual and social features of real-life interpersonal interactions we tested heterosexual men/women and gay men/lesbian women reacting subjectively and physiologically to the observation of a gender-matched virtual body being touched on intimate taboo zones (like genitalia) by male and female avatars. All participants rated as most erogenous caresses on their embodied avatar taboo zones. Crucially, heterosexual men/women and gay men/lesbian women rated as most erogenous taboo touches delivered by their opposite and same gender avatar, respectively. Skin conductance was maximal when taboo touches were delivered by female avatars. Our study shows that IVR may trigger realistic experiences and ultimately allow the direct exploration of sensitive societal and individual issues that can otherwise be explored only through imagination.
