Design And Feedback Research In Underground Space With EEG And Virtual Reality Technology

China’s urbanization promotes the rapid development of cities,but at the same time,it also gives birth to different problems of "urban diseases".Among them,the growth of urban population is one of the important causes of "urban disease".However,the existing urban space cannot match the demand of the growing population for social space resources.In order to reconcile the contradiction between the two,China has accelerated the development of three-dimensional space model in recent years.Underground space can not only alleviate the shortage of urban space resources,provide more social space resources,but also optimize the spatial structure and layout of the above,and improve the urban environmental quality of residents.Therefore,the development of underground space has become one of the key points of future urban development.However,there are still problems in the underground space itself.The connection between underground space and outdoor environment is weak,so it is difficult to introduce the natural environment,which leads to the low quality of the physical environment of underground space and affects the environmental comfort of users.In order to improve the environmental quality of underground space,architects and researchers began to explore the relationship among architectural space,environment and human perception.But there are problems existing research,first,the current research mainly focuses on the concept of underground space theory level,and less to explore the architectural space environment quality,and in which the existing space environment quality in the study,the paper mainly discusses the physical environment parameters on the influence of underground space,the lack of the research on space design parameters,the second,The research based on architecture has the problems of relatively single experimental parameters,incomplete experimental methods and single experimental environment setting,while the research based on neuroscience has the problems of incomplete experimental system and framework.Therefore,in order to solve the above problems and optimize the quality of the space environment of underground space,a new research method based on neuroscience and architecture was constructed.Study adopts the technology of the virtual reality(VR)and laboratory control(LEC)to build virtual simulation space,create immersive spatial experience,using EEG signals(EEG)to obtain the subjects’ physical experimental data,subjective questionnaire and cognitive tests,subjects psychological and the experimental data on the level of efficiency,The coupling relationship between psychology,physiology and efficiency of human perception is obtained,and the correlation between architectural space,environment and human perception is finally analyzed.Based on the above methods,the significance of the research is not only to provide a new idea to convert the inherent human perception into experimental data,but also to construct a new research method to crack and obtain the law among architectural space,environment and human perception,and finally realize the design optimization of underground space.In the first stage,3 different scenes were selected to construct a new research method.The analysis showed that the most active test area in the experiment was the right temporal lobe area and the most active 4 test points.At the same time,β-wave was positively correlated with work efficiency,and β-wave was closely related to people’s psychological level.In the second stage,seven underground space scenes were selected to test the new research method.The analysis showed that the most active regions of human brain in underground space were occipital lobe and parietal lobe.Meanwhile,working efficiency was closely related to βH/βL and indoor color,and green had the most obvious effect on working efficiency.
