Abstract
Description
Technical Field
[0001] This invention relates to the field of virtual simulation teaching technology, and in particular to a teaching device and method based on virtual simulation. Background Technology
[0002] In chemistry teaching, experimental teaching is the core link connecting theoretical knowledge with practical cognition. However, traditional teaching models and existing virtual simulation schemes have long had significant limitations: on the one hand, traditional experiments are constrained by safety risks and resource conditions. Many experiments involving toxic, harmful, and highly irritating substances (such as ammonia, chlorine, and hydrogen sulfide) are prone to respiratory irritation and reagent contamination due to direct operation, so teachers often use textual descriptions instead of actual olfactory experiences. At the same time, high-precision instrument experiments are limited by funding and venue, making it difficult for most schools to conduct them, resulting in students lacking intuitive understanding of key experimental phenomena such as "the characteristics of substance odors." Therefore, to solve the above pain points, this invention provides a teaching device and method based on virtual simulation to complete the multi-sensory cognitive loop of chemistry experiments, balance the needs of safe teaching and real experience, and break the dual dilemma of traditional teaching and existing virtual schemes. Summary of the Invention
[0003] To overcome the shortcomings, the purpose of this invention is to provide a teaching device and method based on virtual simulation.
[0004] Technical Solution: A teaching device and method based on virtual simulation, comprising a hardware module, a software system, and a data interaction module, which transmit data in real time through a communication protocol. The hardware module includes an immersive display unit, an interactive operation unit, and a computing and storage unit. The data interaction module includes a device communication interface and a cloud collaboration interface. The computing and storage unit includes a touch screen with a shelf on one side. The immersive display unit, comprising a VR headset, is placed on the shelf and has an odor generator. A breathing mask is rotatably connected to the VR headset, and a connecting tube connects the odor generator and the breathing mask. The immersive display unit is used to construct a virtual chemical experiment scene. The interactive operation unit, comprising a wireless control handle, is placed on the shelf and electrically connected to the VR headset. The wireless control handle has a built-in sensor and vibration feedback module and supports force feedback to simulate the tactile sensation of experimental operations. The software system is used to construct a virtual teaching model.

Each experimental resource includes a 3D instrument model, chemical principle animation, and a safety precaution pop-up window.
[0008] As an improvement to the above scheme, the interactive operation engine includes a physics engine, a chemistry engine, and an operation judgment module; the physics engine is used to simulate physical phenomena such as liquid flow and gas diffusion; the chemistry engine is used to calculate the reaction process in real time and present experimental phenomena such as color changes and precipitation formation; the operation judgment module presets operation specifications, identifies and prompts students' incorrect operations in real time.
[0009] As an improvement to the above solution, the teaching management module and data processing module support teachers in creating courses, setting experimental parameters, and monitoring students' operation progress and error records in real time. They also provide interactive guidance through remote marking and voice explanation. The data processing module automatically collects operation logs and experimental data, generates personalized learning reports, and supports local storage and cloud backup.
[0010] As an improvement to the above solution, a teaching method based on a virtual simulation teaching device includes the following steps:

The virtual experimental resource library renders 3D instrument models of experimental resources, animations of chemical principles, and pop-up windows with safety precautions. Wearing a VR headset and wireless operating handle, students enter the virtual experimental scene and perform experimental operations.
[0013] S3: Select the instrument in the virtual scene, and assemble the experimental device according to the specifications in the virtual scene through the action feedback of the wireless operating handle. The operation screen will be displayed synchronously on the touch screen, and the operation judgment module will judge whether the assembly is correct in real time.
[0014] S4: Change the independent variable according to the plan, add reagents and start the reaction; the software automatically collects the dependent variable data and generates a real-time data curve.
[0015] S5: Observe key experimental phenomena repeatedly. You can focus on details by using the "slow motion" and "pause" functions on the touch screen. At the same time, teachers can provide real-time guidance and feedback through the screen.
[0016] S6: Teachers provide feedback and evaluation by combining the system score and experiment report determined in real time by the operation judgment module.

[0033] A teaching method based on a virtual simulation teaching device includes the following steps:
