A Software Toolkit for Web-Based Virtual Environments Based on a Shared Database
نویسندگان
چکیده
We propose a software toolkit for developing complex web-based user interfaces, incorporating such things as multi-user facilities, virtual environments (VEs), and interface agents. The toolkit is based on a novel software architecture that combines ideas from multi-agent platforms and user interface (UI) architectures. It provides a distributed shared database with publish-subscribe facilities. This enables UI components to observe the state and activities of any other components in the system easily. The system runs in a web-based environment. The toolkit is comprised of several programming and other specification languages, providing a complete suite of systems design languages. We illustrate the toolkit by means of a couple of examples.

GTrust: a group based trust model
Nowadays, the growth of virtual environments such as virtual organizations, social networks, and ubiquitous computing, has led to the adoption of trust concept. One of the methods of making trust in such environments is to use a long-term relationship with a trusted partner. The main problem of this kind of trust, which is based on personal experiences, is its limited domain. Moreover, both par...
متن کاملVR-MOG: A Toolkit For Building Shared Virtual Worlds
The paper presents a user interface toolkit to support the rapid construction of cooperative virtual environments. The toolkit is based on extending a 2D model of interaction to 3D virtual environments. The toolkit populates a virtual world with shared 3D interface objects which allow deeper semantic interaction with the virtual world. A principal focus of the toolkit is on the provision of acc...

متن کاملHighly interactive web-based courseware
This contribution presents interdisciplinary approaches to develop, interlink, and modify Web-based learning content with special regard to highly interactive content. We describe how we base development of virtual experiments on a toolkit of reusable software components. For proper embedding into courseware we further provide a scripting interface. Authors may create and modify scripts online ...
