Innovative learning

  • Collaborative virtual worlds: our “WebTalk” project for the creation of virtual 3D worlds to support collaboration has generated the Learning at Europe project (link to Learning @ Europe )

This thesis assesses the usability of the WebTalk-I framework, addresses limitations, and lays the foundation structure for WebTalk-II. It also explains whatCooperation Metaphors are.
Start from here to learn everything about WebTalk and its generalprinciples

This thesis introduces the WebTalk-I framework and explains the modalities with which it can be used to support collaboration in visiting a virtual museum

This thesis introduces a methodology for design and deployment of collaborative3D virtual environments, using access structures modeled in XML. It alsoexplains how the metaphors of cooperation, as a set of atomic rules, could be implemented on the design stage and in implementation.

This thesis is mainly technical and describes the software module thatparses the XML descriptions of the scene and builds the graphical 3D representationusing Java 3D.

This thesis advocates the opportunity to create a collaboration channel between mobile users using WAP technologies (cellphones) and users connection to a shared virtual environment with a regular desktop CVE system. A framework that supports this theory has been developed and evaluated.

This thesis evaluates collaboration mechanisms in various CVEs, and defines and proposes a schema to define and define collaborative patterns between users in 3D CVEs. This mode can be applied to the WebTalk-II framework.

This thesis demonstrates the use of automated and pre-programmed avatars to aid navigation and exploration within collaborative virtualworlds

This thesis describes the concept of behavior in webtalk-II and describes its use for the implementation of the virtual bag, an inventory interface for avatars
