The digitally generated worlds of the virtual are not antagonistic to the usual reality, but increasingly develop into homologous alternatives within ordinary reality. The use of technopractices such as virtual reality and communication with algorithm-based virtual entities, which are more and more turning into a (proto-)social element of our society, not only makes the contingency of our world apparent, but also allows us to observe the reflexivity of our own observation of this contingency. Hence, acting and experiencing in virtual worlds and with virtual communication partners does not necessarily imply a loss of reality, but on the contrary, it may bring us multifarious enrichments of reality. However, the cultural process of digitalization also brings in its wake a new narcissistic insult to mankind: Reflected by self-learning machines that reproduce human intelligence to an unimagined degree, we painfully learn that the human self is always merely socially formatted and can operate only within the confines, and by the standards, of habituation and socialization

Comprehensive Study

Virtual Reality (VR) technology offers users the possibility to immerse and freely navigate through virtual worlds. An important component for achieving a high degree of immersion in VR is locomotion. Often discussed in the literature, a natural and effective way of controlling locomotion is still a general problem which needs to be solved. Recently, VR headset manufacturers have been integrating more sensors, allowing hand or eye tracking without any additional required equipment. This enables a wide range of application scenarios with natural freehand interaction techniques where no additional hardware is required. This paper focuses on techniques to control teleportation-based locomotion with hand gestures, where users are able to move around in VR using their hands only. With the help of a comprehensive study involving 21 participants, four different techniques are evaluated. The effectiveness and efficiency as well as user preferences of the presented techniques are determined. Two two-handed and two one-handed techniques are evaluated, revealing that it is possible to move comfortable and effectively through virtual worlds with a single hand only.

This article reports on one stage of a project that considered twenty 8–12-years-olds use of Virtual Reality (VR) for entertainment. The entire project considered this in relation to interaction and engagement, health and safety and how VR play fitted into children’s everyday home lives. The specific focus of this article is solely on children’s interaction and engagement with a range of VR content on both a low-end and high-end head mounted display (HMD). The data were analysed using novel multimodal methods that included stop-motion animation and graphic narratives to develop multimodal means for analysis within the context of VR. The data highlighted core design elements in VR content that promoted or inhibited children’s storytelling in virtual worlds. These are visual style, movement and sound which are described in relation to three core points of the user’s journey through the virtual story; (1) entering the virtual environment, (2) being in the virtual story world, and (3) affecting the story through interactive objects. The findings offer research-based design implications for the improvement of virtual content for children, specifically in relation to creating content that promotes creativity and storytelling, thereby extending the benefits that have previously been highlighted in the field of interactive storytelling with other digital media.

Virtual reality (VR) is the term used to describe representation and perception in a computer-generated, virtual environment. The term was coined by author Damien Broderick in his 1982 novel “The Judas Mandala". The term "Mixed Reality" describes the mixing of virtual reality with pure reality. The term "hyper-reality" is also used. Immersion plays a major role here. Immersion describes the embedding of the user in the virtual world. A virtual world is considered plausible if the interaction is logical in itself. This interactivity creates the illusion that what seems to be happening is actually happening. A common problem with VR is "motion sickness." To create a sense of immersion, special output devices are needed to display virtual worlds. Here, "head-mounted displays", CAVE and shutter glasses are mainly used. Input devices are needed for interaction: 3D mouse, data glove, flystick as well as the omnidirectional treadmill, with which walking in virtual space is controlled by real walking movements, play a role here.

Damascus-born artist, Jawa El Khash’s immersive installation, The Upper Side of the Sky (2020), combines virtual reality and Syria’s natural ecology to confront the physically devastating impacts of war. In response to ISIS’s 2015-16 occupation of the ancient Syrian city of Palmyra, El Khash evaluates the relationship between technology and the environment to explore the ability for virtual reality to rebuild destroyed landscapes and create sites for healing.

Teaching Approach

Since the last few decades, virtual reality (VR) and augmented reality (AR) interfaces have shown the potential to enhance teaching and learning, by combining physical and virtual worlds and leveraging the advantages of both. Conservative techniques of content presentation (fixed video, audio, scripts) lack personalization and interaction.

BACKGROUND Virtual reality (VR) is a digital education modality that produces a virtual manifestation of the real world and it has been increasingly used in medical education. As VR encompasses different modalities, tools and applications, there is a need to explore how VR has been employed in medical education. OBJECTIVE The objective of this scoping review is to map existing research on the use of VR in undergraduate medical education and to identify areas of future research METHODS We performed a search of 4 bibliographic databases in December 2020, with data extracted using a standardized data extraction form. The data was narratively synthesized and reported in line with the PRISMA-ScR guidelines. RESULTS Of 114 included studies, 69 studies (61%) reported the use of commercially available surgical VR simulators. Other VR modalities included 3D models (15 [14%]) and virtual worlds (20 [18%]), mainly used for anatomy education. Most of the VR modalities included were semi-immersive (68 [60%]) and of high interactivity (79 [70%]). There is limited evidence on the use of more novel VR modalities such as mobile VR and virtual dissection tables (8 [7%]), as well as the use of VR for training of non-surgical and non-psychomotor skills (20 [18%]) or in group setting (16 [14%]). Only 3 studies reported the use conceptual frameworks or theories in the design of VR. CONCLUSIONS Despite extensive research available on VR in medical education, there continues to be important gaps in the evidence. Future studies should explore the use of VR for the development of non-psychomotor skills and in areas other than surgery and anatomy.

Virtual Reality (VR) and human interaction with virtual worlds can greatly enhance communication neuroscience research. VR provides opportunities for novel approaches to empirical investigation. This chapter will discuss why VR and the varieties of virtual experience is of interest to communication neuroscientists. This leads to a discussion of multiple issues related to experimental implementation and cognition, and ways VR is useful to communication neuroscience. This includes multiple cognitive effects that provide opportunities for advancing research.

Abstract I argue that virtual reality is a sort of genuine reality. In particular, I argue for virtual digitalism, on which virtual objects are real digital objects, and against virtual fictionalism, on which virtual objects are fictional objects. I also argue that perception in virtual reality need not be illusory, and that life in virtual worlds can have roughly the same sort of value as life in non-virtual worlds.
