Preservation and Exhibition of Architectural Heritage under the Concept of Information Interaction:a Case Study of the XR Exhibition of the Eastern Warmth Chamber of the Hall of Mental Cultivation in the Palace Museum
In recent years,the applications of extended reality(XR)technology in architectural heritage preservation and exhibi-tion have attracted widespread attention.However,previous applications have aimed at displaying outcomes,not yet fully exploiting the unique interactive potential of XR technology.From the perspective of information interaction,this paper explores the path toward realizing an"audience-oriented"XR exhibition model by harnessing the potential to promote the preservation,inheritance,and au-dience interaction of architectural heritage.This paper studies the XR exhibition application development of the Eastern Warmth Chamber of the Hall of Mental Cultivation,an official building from the Ming and Qing dynasties.It illustrates the respective applications of virtual reality(VR)and augmented reality(AR)technologies in online and on-site display.Additionally,it explores how these technologies expand the capacity of per-ceptible information by immersing the audience in virtual or augmented reality scenes of architectural heritage from various angles of space,time,subject,and object.In the spatial dimension,XR technology breaks through the physical limitations of conventional exhibitions.It enables the audience to transition scenes in the virtual world and explore various eras and places,providing them with a comprehensive understanding of the history and evolution of architecture.In the temporal dimension,the XR environment makes events and subjects from different periods coexist within the same scene through level and plot configurations,achieving dynamically interwoven information presentation.Crucially,XR technology transforms the audience from passive spectators to creators,granting them the autonomy to access and explore information.The audience can display information,design their exhibition space,and inter-act with architectural heritage,thereby gaining richer experience through interactivity.In addition,this paper distinguishes between VR and AR technologies and further discusses the applicability of their features to different usage scenarios.VR technology generates an entirely virtual world that immerses users,whereas AR superimposes virtual content into the real world,enabling users to interact with virtual information within their physical environment.Upon these findings,this paper argues that XR technology not only facilitates mass communication but also offers practitioners in architectural heritage preservation an integrated platform for management and monitoring,both online and offline.This platform allows professionals to access information about ancient buildings,and modify and annotate the data to support decision-making.The widespread application of the technology enhances the efficiency of architectural preservation efforts.
