In Virtual Worlds, Benjamin Woolley examines the reality of virtual reality.

This paper develops and offers the theory of embodied social presence (ESP). The paper reviews the literature on place and space, presence, and embodiment and demonstrates that the role of the body as a focal point for action during social interaction in multi-user virtual environments has been largely overlooked. We draw on Activity Theory to frame our model of embodied social presence. Activity Theory proposes that a learner (i.e., a social actor in a virtual environment) derives meaning during interactions with his or her environment through actions, context, and tools and that people perceive reality both as objective (i.e., existing without them) and as socially constructed i.e., (existing within them). Embodied Social Presence Theory focuses on the virtual body (i.e., the avatar) as the nexus of activity in social interaction within virtual environments and we explore the implications of this focus on how actors derive meaning and understanding during social interaction. We examine this theory in a qualitative analysis of reflective data obtained from users of Second Life and find support for the theory. The paper concludes with a discussion of Embodied Social Presence Theory and implications for future research and practice.

This article considers the ethical implications of digital virtual reality (DVR) within the context of the place of virtual reality in general in human life and development. This is elaborated through a comparative analysis of the continuity and discontinuity between virtual reality in other mediated forms and DVR. The important role played by virtual reality in human creativity and adaptation sets the context for considering the ethics of DVR in 4 main areas: epistemological questions, questions of distraction and displacement, the content of DVR, and questions of power.

This paper provides a critical analysis of virtual environments made in recent leisure and cultural studies discussions, which claim virtual reality to be the technotopia of post-modern society. Such positions describe virtual realities as worlds of in nite freedom, which transcend human subjectivity and where identity becomes no longer burdened by the prejudices of persons. Arguing that cyberspace offers little more than a token gesture towards such liberation, the paper suggests a shift in focus from the power relations that might change or remain because of virtual environments, to an awareness of their implications for human beings. Such technologies as chat rooms, the Internet and cyber-sex, are used to illustrate the fundamental challenge of virtual leisure to the human condition. This human condition is often presumed to represent ‘reality/actuality’ and, as such, is said to be in contrast to virtual environments. However, this paper extends its critique of virtual reality, by questioning such a distinction and arguing that new cyber-virtual reality is no more or no less than a sophistication of virtualness that has always re ected the human, embodied experience. Consequently, it is argued how cyberspace is more profound for its challenge to identity construction than for its emancipatory function.

We approach the virtual reality phenomenon by studying its relationship to set theory. This approach offers a characterization of virtual reality in set theoretic terms, and we investigate the case where this is done using the wellfoundedness property. Our hypothesis is that non-wellfounded sets (so-called hypersets) give rise to a different quality of virtual reality than do familiar wellfounded sets. To elaborate this hypothesis, we describe virtual reality through Sommerhoff’s categories of first- and second-order self-awareness; introduced as necessary conditions for consciousness in terms of higher cognitive functions. We then propose a representation of first- and second-order self-awareness through sets, and assume that these sets, which we call events, originally form a collection of wellfounded sets. Strong virtual reality characterizes virtual reality environments which have the limited capacity to create only events associated with wellfounded sets. In contrast, the logically weaker and more general concept of weak virtual reality characterizes collections of virtual reality mediated events altogether forming an entirety larger than any collection of wellfounded sets. By giving reference to Aczel’s hyperset theory we indicate that this definition is not empty because hypersets encompass wellfounded sets already. Moreover, we argue that weak virtual reality could be realized in human history through continued progress in computer technology. Finally, within a more general framework, we use Baltag’s structural theory of sets (STS) to show that within this hyperset theory Sommerhoff’s first- and second-order self-awareness as well as both concepts of virtual reality admit a consistent mathematical representation. To illustrate our ideas, several examples and heuristic arguments are discussed.

This article uses a notorious incident within the computer program EVE Online to exemplify and facilitate discussion of the metaphysics of virtual worlds and the morality of user behavior. The first section examines various frameworks used to understand virtual worlds, and emphasizes those which recognize virtual worlds as legal contracts, as representational worlds, and as media for communication. The second section draws on these frameworks to analyze issues of virtual theft and virtual betrayal arising in the EVE incident. The article concludes by arguing that, in the absence of countervailing contractual obligations, users of virtual worlds have the same de facto duties to each other as they do in mediated and real environments.

Realistic uses of Virtual Reality (VR) technology closely integrate user training on virtual objects with VR-assisted user interactions with real objects. This paper shows how the Interactive Theory of Perception (ITP) may be extended to cover such cases. Virtual objects are explained as concrete models (CMs) that have an inner generation mechanism, and the ITP is used to explain how VR users can both perceive such local CMs, and perceptually represent remote real objects. Also, concepts of modeling and representation are distinguished. The paper concludes with suggestions as to how the ITP methodology developed here could be extended to iconic external representations and models generally.

This essay addresses ethical aspects of the design and use of virtual reality (VR) systems, focusing on the behavioral options made available in such systems and the manner in which reality is represented or simulated in them. An assessment is made of the morality of immoral behavior in virtual reality, and of the virtual modeling of such behavior. Thereafter, the ethical aspects of misrepresentation and biased representation in VR applications are discussed.
