A novel model of constructing virtual laboratory environment

With the swift development of virtual reality technology, virtual environment has appealed more and more attention of educators. To date, many models and architectures are efficient in constructing virtual laboratory environment. This paper presents a novel Problem-driven Virtual Realization (PVR) model that is able to convert the realistic environment to the virtual environment. Based on the PVR model, we propose a hierarchic concept of Functional-Levels that divides the PVR model into five layers to facilitate the transformation of experiment environment. Digital logic experiments based on the virtual laboratory environment was built as an example to indicate its good interactivity and expansibility.
