Scalable peer-to-peer networked virtual environment

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.
