In recent years, thanks to the rapid development of information technology and the strong promotion by education authorities, virtual simulation training has begun to be widely used in higher vocational education, becoming an important part of practical training and a vital means for improving teaching quality. Virtual simulation technology integrates information technologies such as multimedia technology, virtual reality technology, and network communication technology to create a virtual teaching environment that is identical to or similar to those in the real world. Through the integration and control of numerous physical elements within this virtual environment, a virtual simulation teaching system is formed. Virtual simulation teaching technology focuses on improving students’ skill levels, and features multi-sensory perception, immersion, interactivity, and conceptualization. These features are beneficial for teachers’ practical teaching and the development of students’ core professional skills, offering a new approach to addressing the challenges in vocational education such as difficulties in practical training, employment, and related issues. At present, many majors in higher vocational colleges, such as chemical engineering, foreign language teaching, tourism, numerical control technology, welding technology, mechatronics, food processing, fashion design, and others, have adopted virtual simulation-based training methods. Virtual simulation-based training has gradually become an effective approach for teaching reform in higher vocational colleges. The virtual simulation training system developed by Qinhuangdao Yuandao Technology Development Co., Ltd. utilizes advanced virtual reality technology and computer imaging techniques. By integrating these technologies with practical needs and taking into account the requirements of professional training, it has developed product functions that offer a completely new training and teaching model for chemical engineering courses in higher vocational colleges. The virtual simulation training system developed by Qinhuangdao Yuandao Technology Development Co., Ltd. overcomes the shortcomings associated with traditional teaching practices in the chemical engineering field, where such practices are difficult to carry out. By employing an interactive teaching approach, it enables students to observe the structure of equipment and the manufacturing processes as if they were there in person, thereby **increasing students’ enthusiasm for learning and the effectiveness of their learning experience**. A best interactive situational teaching system is one that stimulates students’ interest in learning through 3D virtual scenes or realistic images, thereby helping them to concentrate.
