Comprehensive Listing

We present a candid reflection on the issues surrounding virtual environment design and implementation (VEDI) in order to: (1) motivate the topic as a researchworthy undertaking, and (2) attempt a comprehensive listing of impeding VEDI issues so they can be addressed. In order to structure this reflection, an idealized model of VEDI is presented. This model, investigated using mixed methods, resulted in 67 distinct issues along the model's transitions and pathways. These were clustered into 11 themes and used to support five VEDI research challenges.

In this chapter we will discuss some fundamental questions concerning creation and development of interfaces searching for the best way to promote interaction between the subject and information/interface. It starts from the fact that the fundamental and most revolutionary aspect introduced by the Internet is based on its sophisticated technological mechanisms that enhance substantially the concepts of space, time, perception, representation, limits, distance, presence, etc. Our everyday practices gain access to a new realm, cyberspace, which enables us to embrace multiple experiences where we exist in the propagation of our “Id.” This condition represents a huge challenge, for example, the necessity to (re)design the image we have from the world in its physical and virtual spaces. We discuss the imagined trends related to the conception and development of virtual environments, addressing the issue of virtual environments in three levels of complexity: realized spaces, possible spaces and imagined spaces.

© 2002 IEEE. Recently, virtual environments (VE) have been increasingly used as settings for design and research. Using VE to visualize ideas from the initial steps of design, the architect is challenged to deal with perception of space, solid and void, without translations to and from a two dimensional media. The goal of the authors' studies was to identify how designers use and communicate early design ideas by using immersive three-dimensional (3D) VEs and how they describe 3D volumes using a different media. A series of experiments were undertaken, including navigation- and perception-tasks, designing in IVE, transcription of design, remote communication between design partners and controlled observations. They explored initial intentions of 3D-immersive design schemes, textual descriptions and collaborations within IVE. They discuss frameworks and factors influencing how architectural students communicate their proposals in an immersive Virtual Environment Design Studio, and how this approach of design studio enables to understand volumes and spatial relationships.

User Centered

In some circumstances, immersion in virtual environments with the aid of virtual reality (VR) equipment can create feelings of anxiety in users and be experienced as something “frightening”, “oppressive”, “alienating”, “dehumanizing”, or “dystopian”. Sometimes (e.g., in exposure therapy or VR gaming), a virtual environment is intended to have such psychological impacts on users; however, such effects can also arise unintentionally due to the environment’s poor architectural design. Designers of virtual environments may employ user-centered design (UCD) to incrementally improve a design and generate a user experience more closely resembling the type desired; however, UCD can yield suboptimal results if an initial design relied on an inappropriate architectural approach. This study developed a framework that can facilitate the purposeful selection of the most appropriate architectural approach by drawing on Norberg-Schulz’s established phenomenological account of real-world architectural modes. By considering the unique possibilities for structuring and experiencing space within virtual environments and reinterpreting Norberg-Schulz’s schemas in the context of virtual environment design, a novel framework was formulated that explicates six fundamental “architectural paradigms” available to designers of virtual environments. It was shown that the application of this framework could easily be incorporated as an additional step within the UCD process.

Mixed methods research in developing countries has been increasing since the turn of the century. Given this, there is need to consolidate insights for future researchers. This article contributes to the methodological literature by exploring how cultural factors and logistical challenges in developing contexts interplay with mixed methods research design and implementation. Insights are based on the author’s research experience of using mixed methods in six projects across three African and three Caribbean countries. Three lessons are provided to aid researchers using mixed methods working in developing countries. First, cultural factors call for more reflexivity. Second, adopting a pragmatic research paradigm is necessary. And third, the research process should be iterative and adaptive.

AbstractWhen we use virtual and augmented reality (VR/AR) environments to investigate behaviour or train motor skills, we expect that the insights or skills acquired in VR/AR transfer to real-world settings. Motor behaviour is strongly influenced by perceptual uncertainty and the expected consequences of actions. VR/AR differ in both of these aspects from natural environments. Perceptual information in VR/AR is less reliable than in natural environments, and the knowledge of acting in a virtual environment might modulate our expectations of action consequences. Using mirror reflections to create a virtual environment free of perceptual artefacts, we show that hand movements in an obstacle avoidance task systematically differed between real and virtual obstacles and that these behavioural differences occurred independent of the quality of the available perceptual information. This suggests that even when perceptual correspondence between natural and virtual environments is achieved, action correspondence does not necessarily follow due to the disparity in the expected consequences of actions in the two environments.

Are current virtual environments (VEs) usable by the broad spectrum of people who may wish to utilize this technology? The current study, which examined over 1000 participants, indicates the answer to this question is a definitive ‘no’. Virtual environment exposure was found to cause people to vomit (1.1%), experience nausea (71%), disorientation (70%), and oculomotor disturbances (79%). Overall, 88% of participants reported some level of adverse symptomatology, ranging from a minor headache to vomiting and intense vertigo. These disturbances led 12% of those exposed to prematurely cease their interaction. Dropout rates as high as nearly 50% were found in exposures of 1 hr in length. In addition, long-term aftereffects were found, including headaches, drowsiness, nausea, and fatigue. These problems could substantially reduce the accessibility of VE technology by the general public and thus must be resolved if this technology is to be widely adopted.

The Virtual Environment Operating Shell (veos) was developed at University of Washington's Human Interface Technology Laboratory as software infrastructure for the lab's research in virtual environments. veos was designed from scratch to provide a comprehensive and unified management facility to support generation of, interaction with, and maintenance of virtual environments. VEOS emphasizes rapid prototyping, heterogeneous distributed computing, and portability. We discuss the design, philosophy and implementation of veos in depth. Within the Kernel, the shared database transformations are pattern-directed, communications are asynchronous, and the programmer's interface is LISP. An entity-based metaphor extends object-oriented programming to systems-oriented programming. Entities provide first-class environments and biological programming constructs such as perceive, react, and persist. The organization, structure, and programming of entities are discussed in detail. The article concludes with a description of the applications that have contributed to the iterative refinement of the VEOS software.
