Creating 3D Museums on the Web

Jacek Jankowski, Marek Jozwowicz, Izabela Irzynska, Bill McDaniel and Stefan Decker

During the mini-workshop, we describe a simple to use authoring application, which may help museums to create virtual exhibitions in a quick and intuitive way. We introduce 3dWiki, a 3D wiki engine. We describe step by step how to create a virtual exhibition using 3dWiki: from creating models representing the artifacts, through authoring the textual content, creating the links, to publishing the result on-line.

The 2LIP Model and its Implementations

Jacek Jankowski and Stefan Decker

In this article we present a model for 2-Layer Interface Paradigm (2LIP). 2LIP is an approach for designing simple yet interactive 3D web applications, an attempt to marry advantages of 3D experience with the advantages of the narrative structure of hypertext. The hypertext information, together with graphics, and multimedia, is presented semi-transparently on the foreground layer. It overlays the 3D representation of the information displayed in the background of the interface. We describe implementations of the 2LIP model: 2LIPGarden (HTML context) and Copernicus (wiki context). We want to show that our model can be easily employed to the existing web infrastructure.

3DWiki: The 3D Wiki Engine

Jacek Jankowski, Marek Jozwowicz, Yolanda Cobos, Bill McDaniel and Stefan Decker

We demonstrate one of the potential paths of the evolution of wiki engines towards Web 3.0. We introduce 3dWiki - the 3D wiki engine, which was built according to 2-Layer Interface Paradigm (2LIP). It was developed for use by Copernicus, our vision of a 3D encyclopedia. In the demonstration: (1) We give an overview of 2-Layer Interface Paradigm, an attempt to marry advantages of 3D experience with the advantages of narrative structure of hypertext. (2) We describe step by step how to create an article for Copernicus: from creating models for the 3D background, through authoring the content, creating the c-links, to publishing the result in our encyclopedia. (3) We show how to use a physics engine in our wiki.

2LIP: The Step Towards The Web3D

Jacek Jankowski and Sebastian Ryszard Kruk

The World Wide Web allows users to create and publish a variety of resources, including multimedia ones. Most of the contemporary best practices for designing web interfaces, however, do not take into account the 3D techniques.
In this paper we present a novel approach for designing interactive web applications – 2-Layer Interface Paradigm (2LIP). The background layer of the 2LIP-type user interface is a 3D scene, which a user cannot directly interact with. The foreground layer is HTML content. Only taking an action on this content (e.g. pressing a hyperlink, scrolling a page) can affect the 3D scene.
We introduce a reference implementation of 2LIP: Copernicus – The Virtual 3D Encyclopedia, which shows one of the potential paths of the evolution of Wikipedia towards Web 3.0. Based on the evaluation of Copernicus we prove that designing web interfaces according to 2LIP provides users a better browsing experience, without harming the interaction.

Copernicus - 3D Wikipedia

Jacek Jankowski

In this paper we present one of the potential paths of the evolution of Wikipedia towards Web 3.0. We introduce Copernicus - The Virtual 3D Encyclopedia, which was built according to 2-Layer Interface Paradigm (2LIP). The background layer of the 2LIP-type user interface is a 3D scene, which a user cannot directly interact with. The foreground layer is HTML content. Only taking an action on this content (e.g. pressing a hyperlink) can affect the 3D scene.

Didaskon – Semantic eLearning Framework

Jacek Jankowski, Adam Westerski and Sebastian Ryszard Kruk

The amount of information is growing dramatically fast nowadays. It is a very difficult time for teachers to keep up with changes; this problem also affects eLearning. Without constant maintenance, electronic courses are also getting outdated. Moreover, all of the current solutions seem to underestimate the potential of Web 2.0 idea. The contemporary eLearning systems deliver predefined, rigid courses which usually do not take into account that users are different from each other. We would like to present Didaskon, a framework for automated composition of a learning path for a student. The selection and workflow scheduling of learning objects is based mainly on their description and semantically annotated specification of user profile. Didaskon also derives information aggregated by IKHarvester (informal knowledge harvester) from various Social Semantic Information Sources, i.e., wikis, blogs, fora, and other informal source.
