摘要
In this special issue,the theme is on the application of VR/AR to experiments and training.We include 7papers which can be divided into two sets,one on specific virtual experiments covering chemistry andbiology,the other on the supporting techniques for VR experiments.For the first topic,in the first paper by Mengting XIAO et al.,they present the multimodal interactiondesign techniques,which are applied in augmented reality for chemical experiment.The system canachieve real-time fusion of the gesture,virtual model,and intelligent equipment,which improves the users'real sense of operation and interaction efficiency.
