Abstract

A collaborative educational system has been designed that enables several students in distant locations to share a virtual three-dimensional space. It can be used to perform virtual experiments and carry out creative tasks. Students can dynamically create a new object and modify its properties. The system maintains a consistent status of the virtual space as seen by each student present in a room. An efficient communication method to maintain this consistency is proposed. Within the virtual space, the three-dimensional materials are based on OMG-CORBA, a distributed object modeling architecture. Furthermore a method to create a new object and modify its properties is also introduced. Lastly, after developing and implementing the prototype system, we evaluate the various issues centering on the proposed methods.
