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.

The explosive growth of the number of applications based on networked virtual environment technology, both games and virtual communities, shows that these types of applications have become commonplace in a short period of time. However, from a research point of view, the inherent weaknesses in their architectures are quickly exposed. The Architecture for Large-Scale Virtual Interactive Communities (ALVICs) was originally developed to serve as a generic framework to deploy networked virtual environment applications on the Internet. While it has been shown to effectively scale to the numbers originally put forward, our findings have shown that, on a real-life network, such as the Internet, several drawbacks will not be overcome in the near future. It is, therefore, that we have recently started with the development of ALVIC-NG, which, while incorporating the findings from our previous research, makes several improvements on the original version, making it suitable for deployment on the Internet as it exists today.

This research aims at the realization of a networked virtual environment for the design of three-dimensional (3-D) objects. Based on an analysis of an ordinary collaborative design, we illustrate that a collaborative work space consists of a dialog space and an object space. In the dialog space, a participant interacts with partners, and in the object space with an object. The participants enter the dialog space and the object space in turn, appropriately. In addition, collaborative design of 3-D objects is carried out with multimodal interactions: visual, auditory, and haptic. A networked virtual environment must support these interactions without contradiction in either time or space. In this paper, we propose a networked virtual environment for a pair of participants to satisfy the conditions described above. To implement the networked system, we take into account the necessity of visual, auditory, and haptic interactions, the need for participants to switch between the dialog space and the object space quickly and appropriately, and human ergonomics on the functional space of hands and eyes. An experiment on hand-over task was done to investigate the effect of the networked haptic device with the proposed system. Object layout tasks, such as toy block layout, office furniture layout, city building layout, etc., can be performed by using this environment.

Portable Software

Four challenges to building large networked virtual environments (NVEs) are ever-increasing complexity, fidelity, scalability, and portability. We require a powerful, flexible, efficient, portable software infrastructure to overcome these challenges. We examine one such example, software infrastructure, which is currently the basis of dozens of NVE efforts. Its use of modern object-oriented inheritance and its use of an interpreted configuration programming language meet these requirements while achieving the efficiency to support thousands of entities on current-generation hardware.

Aided Design

A concurrency control mechanism for a networked virtual environment is a key element in many collaborative computer-aided design applications. However, conventional object-based locking mechanisms restrict the behaviors of nonowners, and an attribute-based locking mechanism may produce another problem called task-surprise, which disturbs users' collaboration. In this paper, we propose a hybrid concurrency control mechanism that reduces restrictions of nonowners' behaviors and task-surprises in a networked virtual environment. The proposed method consists of two concurrency control approaches: task-based concurrency control and personal workspaces. The task-based concurrency control approach allows nonowners to do some tasks if they do not conflict with the tasks of the owner of the shared object. The personal workspaces approach provides an independent workspace where a user can manipulate copies of the shared objects. The proposed method was applied to a collaborative level design for a large-scale online game as a case study. We evaluated its performance by experiments and user studies to check acceptance and usability of the proposed method.
