Design and Development of Arbitrary Operation based on VR Chemical Experiment Platform

Abstract

With the complicated nature of chemical drugs, it's uncertain what the dangers will happen when the drug mixing. Therefore, teachers are focused on teaching chemical experiments in theory or using video to explain the experimental principle. Virtual chemistry laboratories have promoted the experimental efficiency and innovated the way of experimental instruction. Students have more opportunities for practicing chemistry experiments. However, most of those two-dimension (2D) or three-dimension (3D) chemical virtual platforms design fixed experiments only, which cannot give users intuitive learning experience. Therefore, the paper proposes an arbitrary operation environment based on a VR device, which divides the chemical experiments into two parts, chemical reaction experiments and molecular chemical experiments. The chemical reaction data are determined by encoding and decoding tables. Besides, the learning of 3D molecular structures is used a voting-CNN, which can give a feedback to learners. Finally, this paper constructs evaluation indicators and performs a statistical analysis, which indicates that the arbitrary operation based on VR chemical experiment platform designed in the paper is basically in accordance with the real world.
