The threshold of the real: A site for participatory resistance in Blast Theory's Uncle Roy all around you (2003)

This article examines the collision of virtual and real spaces through simultaneous live and online play in Uncle Roy All Around You, and how this disruption of immersion is used to expose the habitual engagements associated with the digital interface. The nature of the participants' immersion and the subsequent reintegration into the real will be explored, before attempting to articulate what defines this piece as politically resistant, through discussion of a self reflexive participation, which undermines what Baudrillard terms the 'simulated response' (Baudrillard 1985/1988 p.216

The virtual maze: A behavioural tool for measuring trust

Trusting another person may depend on our level of generalised trust in others, as well as perceptions of that specific person's trustworthiness. However, many studies measuring trust outcomes have not discussed generalised versus specific trust. To measure specific trust in others, we developed a novel behavioural task. Participants navigate a virtual maze and make a series of decisions about how to proceed. Before each decision, they may ask for advice from two virtual characters they have briefly interviewed earlier. We manipulated the virtual characters' trustworthiness during the interview phase and measured how often participants approached and followed advice from each character. We also measured trust through ratings and an investment game. Across three studies we found participants followed advice from a trustworthy character significantly more than an untrustworthy character, demonstrating the validity of the maze task. Behaviour in the virtual maze reflected specific trust rather than generalised trust, whereas the investment game picked up on generalised trust as well as specific trust. Our data suggests the virtual maze task may provide an alternative behavioural approach to measuring specific trust in future research, and we demonstrate how the task may be used in traditional laboratories

Virtual reality interfaces for seamless interaction with the physical reality

In recent years head-mounted displays (HMDs) for virtual reality (VR) have made the transition from research to consumer product, and are increasingly used for productive purposes such as 3D modeling in the automotive industry and teleconferencing. VR allows users to create and experience real-world like models of products; and enables users to have an immersive social interaction with distant colleagues. These solutions are a promising alternative to physical prototypes and meetings, as they require less investment in time and material. VR uses our visual dominance to deliver these experiences, making users believe that they are in another reality. However, while their mind is present in VR their body is in the physical reality. From the user’s perspective, this brings considerable uncertainty to the interaction. Currently, they are forced to take off their HMD in order to, for example, see who is observing them and to understand whether their physical integrity is at risk. This disrupts their interaction in VR, leading to a loss of presence – a main quality measure for the success of VR experiences. In this thesis, I address this uncertainty by developing interfaces that enable users to stay in VR while supporting their awareness of the physical reality. They maintain this awareness without having to take off the headset – which I refer to as seamless interaction with the physical reality. The overarching research vision that guides this thesis is, therefore, to reduce this disconnect between the virtual and physical reality. My research is motivated by a preliminary exploration of user uncertainty towards using VR in co-located, public places. This exploration revealed three main foci: (a) security and privacy, (b) communication with physical collaborators, and (c) managing presence in both the physical and virtual reality. Each theme represents a section in my dissertation, in which I identify central challenges and give directions towards overcoming them as have emerged from the work presented here. First, I investigate security and privacy in co-located situations by revealing to what extent bystanders are able to observe general tasks. In this context, I explicitly investigate the security considerations of authentication mechanisms. I review how existing authentication mechanisms can be transferred to VR and present novel approaches that are more usable and secure than existing solutions from prior work. Second, to support communication between VR users and physical collaborators, I add to the field design implications for VR interactions that enable observers to choose opportune moments to interrupt HMD users. Moreover, I contribute methods for displaying interruptions in VR and discuss their effect on presence and performance. I also found that different virtual presentations of co-located collaborators have an effect on social presence, performance and trust. Third, I close my thesis by investigating methods to manage presence in both the physical and virtual realities. I propose systems and interfaces for transitioning between them that empower users to decide how much they want to be aware of the other reality. Finally, I discuss the opportunity to systematically allocate senses to these two realities: the visual one for VR and the auditory and haptic one for the physical reality. Moreover, I provide specific design guidelines on how to use these findings to alert VR users about physical borders and obstacles.In den letzten Jahren haben Head-Mounted-Displays (HMDs) für virtuelle Realität (VR) den Übergang von der Forschung zum Konsumprodukt vollzogen und werden zunehmend für produktive Zwecke, wie 3D-Modellierung in der Automobilindustrie oder Telekonferenzen, eingesetzt.

Aktuell sind Nutzer gezwungen, ihr HMD abzunehmen, um zu sehen, wer sie beobachtet und zu verstehen, ob ihr körperliches Wohlbefinden gefährdet ist. Dadurch wird ihre Interaktion in der VR gestört, was zu einem Verlust der Präsenz führt - ein Hauptqualitätsmaß für den Erfolg von VR-Erfahrungen. In dieser Arbeit befasse ich mich mit dieser Unsicherheit, indem ich Schnittstellen entwickle, die es den Nutzern ermöglichen, in VR zu bleiben und gleichzeitig unterstützen sie die Wahrnehmung für die physische Realität. Sie behalten diese Wahrnehmung für die physische Realität bei, ohne das Headset abnehmen zu müssen - was ich als nahtlose Interaktion mit der physischen Realität bezeichne. Daher ist eine übergeordenete Vision von meiner Forschung diese Trennung von virtueller und physicher Realität zu reduzieren.

Im Kontext meiner Arbeit werden Räume oder Flächen, die mit anderen ortsgleichen Menschen geteilt werden, als geteilte Orte bezeichnet.

Jedes Thema stellt einen Fokus in meiner Dissertation dar, in dem ich zentrale Herausforderungen identifiziere und Lösungsansätze vorstelle. Erstens, untersuche ich Sicherheit und Privatsphäre an öffentlichen, geteilten Orten, indem ich aufdecke, inwieweit Umstehende in der Lage sind, allgemeine Aufgaben zu beobachten. In diesem Zusammenhang untersuche ich explizit die Gestaltung von Authentifizierungsmechanismen. Ich untersuche, wie bestehende Authentifizierungsmechanismen auf VR übertragen werden können, und stelle neue Ansätze vor, die nutzbar und sicher sind. Zweitens, um die Kommunikation zwischen HMD-Nutzern und Umstehenden zu unterstützen, erweitere ich das Forschungsfeld um VR-Interaktionen, die es Beobachtern ermöglichen, günstige Momente für die Unterbrechung von HMD-Nutzern zu wählen. Darüber hinaus steuere ich Methoden zur Darstellung von Unterbrechungen in VR bei und diskutiere ihre Auswirkungen auf Präsenz und Leistung von Nutzern. Meine Arbeit brachte auch hervor, dass verschiedene virtuelle Präsentationen von ortsgleichen Kollaborateuren einen Effekt auf die soziale Präsenz, Leistung und Vertrauen haben. Drittens, schließe ich meine Dissertation mit der Untersuchung von Methoden zur Verwaltung der Präsenz, sowohl in der physischen als auch in der virtuellen Realität ab. Ich schlage Systeme und Schnittstellen für den Übergang zwischen den Realitäten vor, die die Benutzer in die Lage versetzen zu entscheiden, inwieweit sie sich der anderen Realität bewusst sein wollen.

Synthesizing Multiple Stakeholder Perspectives on Using Virtual Reality to Improve the Periprocedural Experience in Children and Adolescents: Survey Study

Background: Virtual reality (VR) technology is a powerful tool for augmenting patient experience in pediatric settings. Incorporating the needs and values of stakeholders in the design of VR apps in health care can contribute to better outcomes and meaningful experiences for patients. Objective: We used a multiperspective approach to investigate how VR apps can be designed to improve the periprocedural experiences of children and adolescents, particularly those with severe anxiety. Methods: This study included a focus group (n=4) and a survey (n=56) of clinicians. Semistructured interviews were conducted with children and adolescents in an immunization clinic (n=3) and perioperative setting (n=65) and with parents and carers in an immunization clinic (n=3) and perioperative setting (n=35). Results: Qualitative data were examined to determine the experience and psychological needs and intervention and design strategies that may contribute to better experiences for children in three age groups (4-7, 8-11, and 12-17 years). Quantitative data were used to identify areas of priority for future VR interventions. Conclusions: We propose a set of ten design considerations for the creation of future VR experiences for pediatric patients. Enhancing patient experience may be achieved by combining multiple VR solutions through a holistic approach considering the roles of clinicians and carers and the temporality of the patient’s experience. These situations require personalized solutions to fulfill the needs of pediatric patients before and during the medical procedure. In particular, communication should be placed at the center of preprocedure solutions, while emotional goals can be embedded into a procedure-focused VR app to help patients shift their focus in a meaningful way to build skills to manage their anxiety

MetaMosque – Envisioning the Mosque as a Virtual Public Space

Historically, the mosque was not only a space for a communal prayer but also a place for building a community. Today, however, with conflicts and diseases fragmenting society, people are less able to gather physically in large spaces. Out of necessity, people rely on technology to get together and interact virtually. In this context, my research challenges the notion of the mosque as a physical space, proposing, instead, its extension into virtual space. Recent global events pose the question: Can the metaverse offer an opportunity for the mosque to reassert itself as a public space. I propose that a MetaMosque can facilitate vital, spiritual and communal functions—similar to a physical mosque—creating a sense of belonging and unity across social and physical boundaries. Rather than replacing the traditional mosque\u27s capabilities, the MetaMosque attempts to extend them, forming a virtual public space and encouraging a more accessible and inclusive virtual society

Trust in digital asset transactions in a web 3 based metaverse

Abstract. Metaverse is drawing the same attention that the internet had received during the Y2K era when internet was a new technology and still evolving. In the similar way, metaverse is still a long way from mainstream adoption and is constantly evolving. Web 3 metaverse or the open metaverse is decentralized using blockchain technology. With blockchain technology, also known as the “trustless” technology, there seems to be no need for the traditional trust concepts in exchanges made in the metaverse ecosystem. In this research, trust in transactions made in the exchange of digital assets in the Web 3 metaverse is explored. Five traditional trust concepts, namely system trust, institution based trust, homophily trust, fast trust and performance based trust are taken into consideration and their dominance level was analyzed to know if they have an impact in purchasing decisions made in the Web 3 metaverse. To have a holistic idea of trust at play, trust in collaborations and business relations in the metaverse is also explored. For this study, information was gathered by means of semi structured, in-depth interviews with seven respondents. These respondents are all active in the metaverse, having made some transactions in the platforms. The findings show that institution based trust or the trust in the brand is currently the most dominant when it comes to both transactions and collaborations in the metaverse even with the new “trustless” technology. One of the contributions of this study is that traditional trust concepts still play a major role in the metaverse and categorizes the level of dominance of each trust type. The study also further confirms the previous literature based on institution trust and other trust concepts. Furthermore, several managerial implications are presented for businesses in the metaverse based on the conclusion. Businesses should work on reputation management and establish a trust mechanism. This can be done through smart contracts with the help of AI that ensure safety, transparency, and accountability in transactions. Creating digital twins to encourage purchases at the beginning stages of business in the metaverse as the real world trust is carried forward to the virtual world of the metaverse is also important

The age of hybrid events: amplifying the power of culture through digital experiences (Music Festivals feat. Technology)

Music festivals represent a significant part of culture as identity shapers and experience providers. With the growing use of technology in all structures of society, music festivals are not aside and have been embracing technologies as a way of creating a value offer and differentiation factor. Livestreams, cashless systems, digital events along with the use of virtual reality and social media have been ways to create a meaningful and immersive experience to the attendees and promote engagement and commitment with the music festival as a brand. This study demonstrates exactly how the implementation of technology in music festivals, thus making them hybrid, affects the overall experience of the attendee. It shows the advantages, challenges and in what specific ways it can affect the event for the promoters and the attendees, along with what aspects organizers need to acknowledge when considering embracing hybrid experiences in their festivals. It creates awareness and raises debate about this increasingly reality, providing the organization trustworthy insights about the topic of digital and/or virtual experiences

Are Male and Female Avatars Perceived Equally in 3D Virtual Worlds?

Virtual worlds are three-dimensional, computer-generated worlds in which users take the form of avatars and use those avatars to interact with objects and other avatars in the virtual world. Virtual worlds are growing in importance in both educational institutions and businesses. Educational institutions have adopted virtual worlds as a medium for instructional delivery whereas businesses are using virtual worlds for recruitment, training, collaboration, and marketing. Given these emerging phenomena, a better understanding of behavioral and perceptual issues in virtual worlds is warranted. We propose a research model to study the interaction effects of gender stereotypicality of male and female avatars and gender typicality of tasks on trust perceptions. Gender stereotypes have been widely studied in the real world along with their effects on trust perceptions. An experiment is proposed to examine the effects of gender stereotypes on trust perceptions in virtual worlds. Implications and expected contributions are also discussed
