Research On Virtual Feedback Design Method Of Space Scenario Basing On Multidimensional Physiological Perception

In the context of the information age,the target of architectural design has gradually shifted from pursuing spatial aesthetics and visual art to focusing on users’ practical experience and space feelings.However,the existing method of architectural design is more based on the designer’s subjective judgment,and it isn’t easy to collect and present the objective needs of the users who lack professional knowledge.It is not easy to intuitively and vividly understand the design ideas and provide feedback during the design stage.On the other hand,the method for designers to obtain feedback mainly relies on the user’s vague and non-quantified subjective description,which is subjective.How to accurately get the users’ objective emotional and cognitive feedback has become an important issue that needs to be solved urgently to promote architectural design’s scientific development.This research attempts to obtain more objective users’ perception feedback data before the project is completed to provide auxiliary design and optimization methods for the existing architectural design method.This research aggregated virtual reality technology and physiological perception measurement technology to establish a virtual feedback design process.For one thing,it can helps designers combine the user’s physiological perception changes in the space and predict whether the design ideas and emotional conceptions can achieve after finishing construction in the future.What’s more,it can help designers optimize the design’s scheme during discusstion process and provide an objective basis for comparison and selection comparison scheme.The research methods this research used including quantitative research,interdisciplinary perspectives research,empirical research,etc.A feedback design method that objectively reflects the user ’s feelings in the space is constructed based on the comprehensive perception detection of multi-dimensional physiological indicators(heart rate,skin electricity and eye movement)and virtual reality.The actual project case is used for demonstration research to validate this method’s feasibility in the practical application of design.This research content mainly included analyzing relevant theories and foundations,constructing the implementation process of feedback design methods and empirical research using feedback design methods.Firstly,this research proposed a feedback design method based on multi-dimensional physiological perception,combining with a review of relevant theories and technology applications at home and abroad,and discussed its necessity and innovation.Besides,this research discussed the implementation process of the feedback design method.The process meanly included virtual scene construction,scene factor extraction,multi-scheme generation,multi-dimensional physiological data collection and processing,personal survey feedback check,scheme comparison and optimization suggestions,etc.Finally,this research took the campus outdoor space scene of Harbin Institute of TechnologyShenzhen International Design Institute as the object of empirical research.Based on the designer’s concept and goals,contrasting schemes were formed for users to perceive and experience.To sum up,this research combined multi-dimensional physiological perception measurement technology to obtain the user’s objective feedback on the architectural space from a physiological and psychological perspective.Through quantitative analysis,researchers can get the users’ more realistic perception result that was not influenced by subjective feeling to assist designers in scheme improvement.This research is expected to provide auxiliary and optimized design methods for architectural space design and provide an objective proof for scheme comparison and selection.
