3DVRLab: A virtual reality learning tool for electrical teaching experiments

In this artical, an instructional software called 3DVRLab is introduced for electrical teaching experiments, which is designed elaborately based on the virtual reality(VR) technology. Most conventional instructional softwares are lacking in interactions with users, while the 3DVRLab overcomes this shortcoming. There are two highlights in the operation subsystem: users can place experimental apparatuses onto the virtual console and connect them freely; the subsystem will detect circuits connected by students intelligently, then give a mark accordingly. For the purpose of a convinced score, we proposed a novel detection algorithm to work out the incorrect apparatuses or connecting wires from the “standard answer”.
