Abstract

Virtual Reality (VR) technology has already entered into the area of the educational software and delivers systems where the trainees can use interactive virtual microworlds and benefit by transfer of experience, interacting directly with the learning domain. This paper describes the Virtual Multi Flow Graph (Virtual-MFG) graphical formal model and the Interaction Specification Workspace (ISW) software architecture for the interaction specification and design of VR applications with emphasis on educational software. The interaction designer specifies the interaction issues of the final system formally, using the tools of ISW. The virtual microworld's objects database is updated with these interaction specifications which include both the virtual objects' dynamic properties and their tutoring capabilities. The model is validated by applying it on an existing VR educational software (EIKON). The Virtual-MFG graphs specifying a learning scenario of EIKON along with the application of ISW on EIKON are also presented.
