Research On Immersive Virtual Experimental Environment Based On Visual Emotional Design

In the process of knowledge progress and the rapid development of science and technology,the application of new media and new technology in the field of education is becoming more and more diversified.Virtual reality technology has gradually infiltrated into various industries,the state supports the application of virtual reality technology in education and teaching from the policy.Virtual reality technology has been introduced into various fields of modern information education,which can be widely used to achieve some teaching objectives that cannot be accomplished by traditional educational means,changing the traditional classroom model and making students’ learning methods more flexible and diverse.At present,virtual reality technology in the field of education is widely used in virtual classroom teaching,virtual experiments,role playing and other aspects.However,there are still some problems in the current application of virtual reality technology in the teaching of digital courses in China,such as paying too much attention to the learning of knowledge and skills,ignoring the emotional experience of students,and causing high cognitive load of learners.With visual cognitive theory,this study of multimedia learning cognitive emotion theory as the theoretical support,such as the visual elements of virtual environment and corresponding to the emotional state of correlation analysis,analyze the visual cognitive mechanism of learners in a virtual environment and characteristics of the analysis of traditional learners,network learners’ characteristics and explore with the intersection of virtual experiment learner characteristics,and then build a virtual experiment learners visual cognition model.Based on the previous research experience,two main visual elements were extracted,based on which the emotional design of the virtual experiment environment was carried out.The low carbon steel tensile in construction mechanics was selected as the research object.According to the design principles of virtual experiment,the virtual experiment scenes in four different environments were designed to prepare for the empirical study of virtual experiment.In model building,on the basis of experimental design,the integration of virtual experiment and real experiment,the actual experiment teaching,the integrate application of virtual experiment and real experiment,experiment teaching,can follow the real experiment,on the basis of virtual experimental teaching environment for students,to students as the main body in the teaching of,in virtual experiment for auxiliary teaching,let the mutual integration,conduct the teaching activities.The emotional state data of learners in the virtual environment were obtained through questionnaires.A total of 60 subjects were divided into four groups.The results of multivariate test showed that the color design in the virtual laboratory environment had no significant influence on the emotions of learners,while the scene complexity had a significant influence on the emotions of learners.It shows that learners’ emotions fluctuate little under different virtual environment tones,and the scene layout has a more prominent influence on the emotions of virtual experiment learners.According to partial least squares regression analysis,the conclusion is that the two visual elements are considered together.The results show that the design parameters of visual elements in the virtual experimental environment can predict learners’ emotions during the experiment,and the optimal combination of the two visual elements selected is the complex group of warm colors.It shows that the combination of these two visual elements at the level of these two elements is easier to stimulate learners’ emotions.This study enriches the theoretical exploration of emotional design concept in virtual experimental environment,and explores the application practice of emotional design teaching in virtual environment for learners,which can provide some reference for subsequent research.
