Research on Interaction Design of Chemical Inquiry Virtual Experiment Based on Augmented Reality Technology

The rapid development of Augmented Reality (AR for short) has promoted great changes in teaching methods in recent years. The technical characteristics of AR and its educational value drive middle school chemistry experiments to gradually develop towards the direction of strong interactivity, interest, and visualization. However, how the interactive content of Augmented Reality meets the core demands of users to improve the learning effect in chemical experiments has become a new topic for educators and interaction designers. Under the technical background of Augmented Reality and guided by Inquiry-based Learning theory, how Augmented Reality interactive information can assist and guide users to conduct experimental exploration is explored in this paper with the guidance and middle school chemistry virtual experiment as the main study object. Based on considerable investigations and studies, the experiment of sodium and water reaction is taken as an example to design the human-computer interaction interface in the experimental scenario. In this design, the situational information required by users is superimposed on the real experimental environment in real time, contributing to improving the exploration consciousness of users, reducing the distraction of their attention and cognitive load, and deepening their understanding of the experimental content. In this study, the design of the 3D space interaction interface based on Augmented Reality technology is investigated, providing great reference value to the interaction design based on Augmented Reality applications.
