“…After the introduction of the first human-scale immersive virtual environment, several architectural applications were researched and proposed to support the architectural design process. For example, Leigh reported a study about the multiperspective collaborative design process in a networked virtual environment and CALVIN, a collaborative architectural layout with immersive navigation (Leigh, 1996). He developed the techniques required to support general collaborative work in persistent virtual environments.…”

In order to improve the quality of everyday life in urban areas, it is important to properly design public spaces such as plazas and streets where urban residents spend many hours during commuting and their spare time. One of the hardest problems at the initial stage of environmental design is the verification and evaluation of the planning of environmental space before actual construction. The virtual reality (VR) technology could be one of the solutions for this kind of problem. Although several technologies have been introduced, such as head-mounted display (HMD) and PC-monitor-based VR (including web-3D), the lack of a sense of presence, as well as interaction methods are still unresolved issues. Therefore, we are suggesting the use of a multiprojection display system with multimodal interfaces, which is our original system for virtual experience, as a potential candidate to solve the lack of presence and interaction. In this study, several experiments related to urban environmental design evaluation have been carried out. The first was about the evaluation and verification of public space design such as those of arcades and eaves above streets between high-rise buildings. The result showed that there was an emotional release from the oppressive feeling in the streets between high-rise buildings when an appropriate arcade design was adopted compared with when no arcade was adopted. The second was about human behavior in public open spaces concerning seat preference in public squares and the distribution of the surrounding people. Furthermore, we carried out several basic psychophysical experiments on human distance perception in virtual space, which revealed the compression of distance perception in VR space. In this paper, we also introduce one of the main points of this study, which is the unique and elaborate cooperative relationship between architectural and nonarchitectural departments of our university when conducting human behavior experiments using heavily computeroriented devices. To carry out the experiments, the multiprojector display system, D-vision, which has a 180º viewing angle, and the original navigation interface, Turn-table, were used to provide a high sense of presence and high-resolution images to the user.

The MagicBook is a Mixed Reality interface that uses a real book to seamlessly transport users between Reality and Virtuality. A vision-based tracking method is used to overlay virtual models on real book pages, creating an Augmented Reality (AR) scene. When users see an AR scene they are interested in they can fly inside it and experience it as an immersive Virtual Reality (VR). The interface also supports multi-scale collaboration, allowing multiple users to experience the same virtual en vironment either from an egocentric or an exocentric perspective. In this paper we describe the MagicBook prototype, potential applications and user response.

“…CALVIN (Collaborative Architectural Layout Via Immersive Navigation) [Leigh et al, 1996] was a collaborative virtual environment that allowed multiple users to synchronously and asynchronously experiment with architectural room layout designs in the CAVE. Participants were able to move, rotate, and scale architectural design pieces such as walls and furniture.…”

“…In many existing collaborative VR applications, participants typically all view and modify the same representation of the data they are viewing. It is our belief that a greater benefit will be derived if the participants are given the power to create and modify their own representations, based on their particular areas of interest and expertise [Leigh et al, 1996;Smith and Mariani, 1997;Gutwin and Greenberg, 1998, Jaa-Aro and Snowdon, this volume].…”

In this chapter we will discuss our work to enable effective collaboration between remote participants within immersive virtual reality environments. We will discuss several of the environments we have created, the lessons we have learned, and the issues that are driving our current research. Our focus is on high-quality collaboration among a handful of participants connected by high-speed, high-bandwidth national and international networks in areas such as scientific visualization, education, and design. Sharing these virtual environments with your remote collaborators as well as the topic of your collaboration may be better than collaborating with them in person, as you can now collaborate while standing inside your data, sharing the context of your discussions.
