Method for constructing and demonstrating teaching content of open type virtual experiment

Abstract

The invention discloses a method for constructing and demonstrating the teaching content of an open type virtual experiment. The method is characterized by comprising the following steps: 1, acquiring or manufacturing virtual experiment component data by a user and modeling virtual experiment components by utilizing the data, wherein the data comprises display data and parameter data; 2, storing all virtual experiment component models into a virtual component library; 3, selecting required virtual experiment component models from the virtual component library according to the requirement of the user and building an experiment scene by utilizing the virtual experiment component models; and 4, setting operating parameters of the experiment scene, operating the experiment scene, transmitting logic information generated by operation of the experiment scene to a calculation module and dynamically demonstrating the calculation result. By the method, the open property of the virtual teaching experiment is improved, and the user can increase the virtual experiment components as required and set the operating parameters of the experiment scene to perform the virtual experiment.

Description

technical field [0001] The invention relates to the fields of image processing, computer graphics, virtual reality and computer-aided teaching, in particular to an open virtual experiment teaching content construction and display method. Background technique [0002] Virtual reality takes computer technology as the core and combines relevant science and technology to generate a digital environment that is highly similar to a certain range of real environments in terms of sight, hearing, and touch. Users interact and interact with objects in the digital environment with the help of necessary equipment. Influence can produce the feeling and experience of being in the corresponding real environment. In recent years, more and more virtual reality technology has been applied in the field of education, among which the virtual experimental teaching environment is a typical representative. The virtual experiment teaching environment can provide a virtual experiment environment for ...

Problems solved by technology

[0004] At present, some progress has been made in the research and application of virtual experimental teaching environment at home and abroad, but except for the virtual instrument development software of NI, there are not many mature commercial platforms, and there is basically no general development platform

In 2001, Zeng Huanwen and others from Taiwan Normal University designed and implemented an interactive virtual laboratory based on an expert system, but this system is only suitable for motor experiments

[0007] However, the existing virtual experiments are all closed, and the virtual experimental components designed by developers are limited. Users can only select virtual experimental components in the existing virtual experimental component library for experiments. If they want to add other experimental components, they can only Waiting for the design of software developers increases the development cost of virtual experiment components

And the existing virtual experiment is only for a specific experiment, the parameter data of the virtual experiment components and the operating parameters of the experimental scene are specific, and virtual experiments with different parameter states cannot be carried out
