AR application enables students to contact the virtual 3D model in person to enhance the learning experience and the interactivity of the experiment. Students and teachers can operate virtual equipment through gesture recognition, and the classroom experience jumps up from 2D to 3D. At the same time, each experiment can be operated repeatedly, and the operation data can be recorded. Teachers can comment on students’ operation, so as to improve students’ interest in learning and activate students’ participation.

AR technology is based on the real world, allowing users to interact with the virtual enhanced data. The phenomenon produced by 3D technology is realistic and vivid, providing a convenient and safe platform for exploration, and help students to explore and study deeper knowledge in the way of interactive operation. Like real phenomena, experimental phenomena can cultivate students’ observation ability, logical thinking ability, and stimulate students’ interest in learning.

Also, It can provide a virtual laboratory for teachers and students, which is much safer than the real laboratory. It can reduce the probability of accidents. At the same time, the virtual experimental equipment will not produce the consumption of experimental materials, and avoid the waste of instruments and drugs.

In traditional experimental teaching, teachers will first explain the knowledge through textbooks, PPT, video, and other forms. If possible, they will take students to the lab for an experiment. Sometimes the experimental reaction time is too long to show in class, students can only listen to the teacher’s explanation. Through AR technology, teachers do not need to carry too much experimental equipment, students do not need to change the classroom, they can just stay in the conventional classroom and do the experiment directly through the AR application. That will save a lot of teaching time and improve the efficiency of teaching.
