Design Of Virtual Electronic Circuit Laboratory Based On Unity3D

As a new system simulation technology developed in recent years,VR technology provides a new teaching idea for education and teaching.Virtual reality technology has three characteristics of immersion,interaction and creativity,which can create a virtual experimental environment with multiple interactive means,lifelike and advanced,and has the technical conditions to build a virtual laboratory.The main theme of this thesis is to combine virtual reality technology with STEAM education concept,and take the electronic circuit experiment subject as the object,and establish a virtual experiment platform through VR technology and other means to provide users with a realistic virtual experiment scene and help users who are new to the electronics discipline Faster understanding and learning of electronic disciplines.The main work of this paper is summarized as follows:(1)The experimental platform takes the steam education concept as the core,combines the circuit welding experiment with the five core elements of the steam education concept,and designs six VR experiments according to the project teaching mode,such as the night light,stopwatch,etc.Help students to understand electronic science from the beginning to the end in a scientific way.(2)The experimental platform consists of three functional modules,the virtual laboratory is mainly based on the virtual circuit welding experiment of PC terminal;in the circuit knowledge display area,augmented reality technology is used to assist users in three-dimensional observation and learning electronic component knowledge;virtual reality laboratory uses VR technology,relying on VR equipment to help users complete the electronic circuit welding experiment in virtual environment.(3)The virtual experiment platform is developed with H5 language,and the experiment website of virtual laboratory is designed.The experiment part is made by unity3 d development engine,and script is developed by C# programming language to realize the circuit welding and interaction function of virtual laboratory.The model in virtual laboratory is modeled by 3dMax modeling tool.The combination of virtual reality technology and STEAM education concept can greatly encourage students to learn electronic science and technology,mobilize students 'enthusiasm,increase students' learning interest,and guide them to master the learning spirit of autonomous learning and exploration.
