Context Construction and Virtual Human Based Intelligent Navigation in Virtual Experiment

In view of the problems of high cost and many potential hazards in real middle school experiments, we construct a virtual experiment simulation situation with virtual human guidance in experiment operation, intelligent algorithm assistance in experiment failure, and systematic evaluation at the end of experiment. First of all, the experimental rule library is established, including: experimental process, trigger standard, coding standard and error content. Secondly, based on these libraries, the flow of system algorithm is designed. Finally, take the experiment of heating potassium permanganate to produce oxygen as an example. The flow design, scene design and virtual human design of the experiment are given. Realize intelligent assistance and interactive real-time guidance of the experimental process.
