Effect Of Audio-visual Environment In Public Spaces Of Large-scale Store Buildings

With the society development,large-scale store buildings under the Internet economy time have developed new architectural fuctions beyond traditional one.Among them,the public spaces develop from the traditional transportation space to the experiential and immersive direction,and become the core space carrying multiple functions.On the basis of human perception and experience,the design of public spaces of large-scale store buildings with environmental sense of belonging and spatial attraction has gradually become an important key point for the study and design of store buildings.Previous studies are mainly based on the local and then,to promote the continuous development of store buildings.However,there is a lack of close connection with the real store environment,a lack of research on the specific scene environment in China,and a lack of research on the core demand of optimizing user experience.In this paper,through research methods like literature review,cluster analysis,field survey and online questionnaire,audio-visual lab experiments,and eye tracking experiment,the comprehensive system of perception characteristics of audio-visual environment in the public spaces of large-scale store buildings has been conducted,like the objective status of public spaces,auditory environment perception characteristics,visual environment perception characteristics,eye movement characteristics and audio-visual interaction,and finally put forward the audio-visual environment design strategy of the public spaces of large-scale store buildings.First,the basic situation of the public spaces of store buildings was gained through literature review and field survey,including space scale,objective status of audio-visual environment and perception status of audio-visual environment.Public spaces was devided into six basic spatial units by clustering analysis.The public space system is the different combination sequence of the six basic space units.Through on-site investigation records,the activities of the public spaces of the store buildings are summarized,and the results of on-site survey was compared with the actual scene to understand the current audio-visual environment and the perception status of the audio-visual environmentThen,audio-visual environment perception and audio-visual interaction in the public spaces of store buildings were studied through the audio-visual environment perception experiment in the laboratory.In terms of perception of the audiovisual environment,results show that background music,natural elements with the combination of green plants and daylight or single natural element in large-open spaces,and low color saturation can significantly improve satisfaction,promote approach behavior;With the appearance foreground music,periodic elements such as festival decoration,the presence of red color,and the strong brightness difference between the main colors will significantly improve the arousal degree.Participants have longer gaze duration for people and faces,readable contents,special and complex and figurative decorations,and for contents that cannot be quickly understood in the visual environment.Color effects individuals differently with the embodied and referential meanings.Further study on audio-visual interaction explored the impact of audio-visual interaction on individuals in the public spaces of large store buildings.There are two phenomena of the audio-visual interaction: They are “consistent-weakening,” i.e.,when the visual element is consistent with the specific auditory element that conveys the same information,the correct perception proportion of the auditory element that constitutes the “consistent” decreases;and “overall perception,” i.e.,people perceive the environment as a whole,instead of disassembling the perception into several elements.
