Study On Spatial Cognition And Wayfinding Of Large Medical Building Complex Under The Influence Of Atrium

In the era of rapid economic development,in order to meet people’s higher demand for medical treatment,large-scale general hospitals continue to emerge,atrium and other new space types are widely used in large-scale general hospital buildings,which put forward higher requirements for space design.Does atrium play a positive role in the formation of patients’ spatial cognition and the improvement of wayfinding efficiency? Will the huge absolute scale medical buildings and the individual factors of the patients lead to the reduction of wayfinding efficiency and urgent wayfinding demand? How does the atrium in a large-scale comprehensive medical building affect people’s spatial cognition and wayfinding after it is combined with other spatial and environmental elements? The solution of these problems is of great significance to optimize the spatial design and improve the patient’s medical experience.There are few researches on wayfinding the spatial factors in the existing medical building research.The research on general spatial cognition and wayfinding has made some achievements,but there are few researches on atrium elements.Therefore,this study attempts to explore the role of atrium and its related elements in the spatial cognition and wayfinding of large-scale comprehensive medical buildings by using a variety of methods and technical means based on the investigation of medical buildings,combined with the research of patients’ individual factors on spatial cognition and wayfinding needs,and the simulation experiment analysis of atrium and related variables.Based on the investigation and analysis of the medical building cases,taking the large-scale third class a general hospital in Wuhan as the field research object,through the basic data collection,field research,data analysis and case study,the status quo laws of the atrium space and streamline types of eight hospitals are obtained.There are two types of flow lines: encircling flow line and separating flow line.The hospital outpatient service of encircling flow line has better visibility and reachable frequency than separating flow line,and the logo setting is more reasonable.Then,the study explored the personal factors,the spatial layout related to atrium,the correlation between spatial cognition and wayfinding by issuing on-site questionnaires to patients in two typical hospitals.Questionnaire analysis excluded the influence of various personal factors on spatial cognition and wayfinding,but found that the difference of atrium visibility in hospital streamline layout had significant effect on spatial cognition and wayfinding evaluation.However,the atrium can improve the negative effects of hospital space and environmental factors on users’ physiological status.The research continues to eliminate the influence of redundant variables by virtual simulation experiment,and promotes the quantitative research on the specific characteristics of atrium and related factors.In the first experiment,eight 3D vr virtual space models were used to explore the specific characteristics of the interaction between absolute scale and atrium variables.Through cognitive map and questionnaire,it can be concluded that subjects can correctly identify atrium and its characteristics in each group of spatial scenes in the spatial cognitive stage.Atrium has a greater impact on the distance judgment of relative path on both sides of atrium than absolute scale,which is not conducive to the distance judgment of relative path on both sides of atrium in various absolute scale scenes.In the wayfinding stage,the increase of absolute scale leads to the increase of wayfinding errors,but atrium can expand the space range of correct wayfinding under different absolute scales,which has a positive impact on wayfinding behavior.In the second experiment,five 2D building space models were built on this basis,and the specific effects of two variables of atrium on space cognition and wayfinding were discussed.The conclusion shows that the visibility of atrium has a positive effect on spatial cognitive judgment and wayfinding.When atrium is located in the middle of streamline,the effect is most obvious,but it will reduce the accuracy of path distance and atrium position judgment.Atrium has a high degree of recognition and attention,which can be used as a spatial positioning benchmark in complex space.Finally,based on the above experimental conclusions,this study provides further discussion and suggestions for the spatial cognition and wayfinding design of large-scale comprehensive medical buildings.
