## Abstract

To address the spatial and temporal limitations of historical museums, a panoramic virtual dynamic display system for digital museums is designed using visual interactive technology. The VM file is generated by using the Digital Museum Design module to obtain a list of available objects, and the VM file is analysed by the Digital Museum View module to stretch and change the two-dimensional flat map into a three-dimensional spatial map for viewers to browse. The system software designs the technical construction process of the digital museum, uses a linearisation algorithm to calculate the number of clicks, visualises the font according to the number of clicks reflecting the weights, and builds a tag cloud component to provide interactive services to facilitate efficient understanding of the museum information by the viewer.

## Body

## 1. Introduction

When browsing through museums, people are constrained by the conditions and time available to view ancient artefacts up close and for long periods of time. To address the spatial and temporal limitations of historical museums[1], digital museums have emerged. The definition of a digital museum is narrowly defined as the reproduction of museum exhibits through digital technology, and broadly defined as a virtual representation of the real world that exists only within the network [2]. As an integrated result of technological applications combined with artistic displays, the digital museum has one of the most important characteristics—interactivity [3]—which determines whether the visitor can have a high-quality visual interactive experience during the visit [4].The rapid development of technology has led to the maturation of multimedia and VR technologies, and interaction technologies have now evolved from static two-dimensional interfaces to multidimensional information spaces [5], with the basis for this leap forward being research and design for multilevel, dynamic user behaviour in virtual environments. Therefore, the design of a panoramic virtual dynamic display system for digital museums based on visual interaction technology will facilitate visitors to access and understand museum information more efficiently [6–10].Virtual reality combined with architectural sketch models allows the imagination to be realised and the spatial experience to be experienced from a human perspective, changing the building form and the relationship with the site at any time according to the actual spatial experience [11]. The change in spatial perception brought about by the change of form can be experienced at any time, and the ambiguity and coherence of the design will not be interrupted, while the digital graphic representation is at the same time precise and easy to adjust later [12].


## 2. The Advantages of Combining Virtual Reality with Architecture

### 2.1. Moving Away from the Traditional Linear Design Process

Most designers today still prefer sketching in the early stages of architectural design [13, 14]. Sketching is an interactive process of visual design thinking, where the architect's design concept and imagination are clues to the meaning of the sketch, while this abstract graphic medium triggers the architect's imagination. However, the vagueness of the sketch design often makes the building shape limited by the site a large gap from the imagination, and the preconstruction design is often we always want a “so big” building, rather than a building with precise volume. The current predesign process is often a combination of sketching and sketching of moulds to find the most suitable solution [15].It is a process of discussing the relationship between space and space, between building and site. This process is often a compromise between imagination and actual scale, between sensibility and rationality [16]. In this case, sketches or sketches are often inappropriate in terms of their actual size, or in other words, they are only good for looking at, but not for using [17].


### 2.2. Immersive Experience Architecture

In conducting architectural design often through the designer's perspective of a bird's eye view or master plan, few designers are able to tour the space from the user's or visitor's perspective, which is largely limited by the designer's imagination and spatial perception [18]. Through virtual reality labs, designers can refine their architectural proposals through 3D visualisation, interactive controls and group discussions. This method of learning provides a vivid learning journey that allows designers to understand their knowledge better than if they were instructed or lectured individually by a teacher, who can ask designers to tour their own spaces as users and experience the differences between different design perspectives [16]. It is often easy for junior designers to design a building in such a way that the connection between the plan and the façade is severed or only one of the two is emphasised, often resulting in windows that are well designed on the façade but do not work well from an internal user perspective, or even dark room for the sake of the façade. Often the window arrangement on the façade is completely different from what was thought of in the earlier plan design. Students often prefer to follow the OMA (Figure 1) approach of a spatial structure + curtain wall, using floor-to-ceiling windows or simply not opening them on the façade, but rarely do they consider the impact of windows on the perception of space and changes in light and shade in the interior, because the existing teaching and architectural presentation is not sufficient to express the changes in light and shade that windows bring to the interior [19]. Virtual reality combined with architectural education brings more new design ideas than traditional teaching, such as design from the perspective of window openings and interior light and shade or comfort of use.Figure 1

### 2.3. Assisting Designers with a Sense of Scale

By combining virtual reality software with modeling software such as Sketch up and Rhino to create virtual reality scenes, designers can experience the spatial layout, flow and building materials of an architectural design in an 'immersion' way, changing the traditional situation of using only photographic materials and drawings to describe the interior and exterior of a building. It facilitates the designer's understanding of the architectural space [20]. The difficulty of translating the physical dimensions of a building space into a physical perception is addressed. Virtual reality can be an alternative when site visits are costly and difficult to arrange due to health and safety issues. The combination of virtual reality experience of different architectural space and lectures by teachers can better assist designers in understanding space and scale. Building setbacks, safe evacuation distances and other codes are no longer cold numbers for designers, and virtual reality can be used to simulate space that does not meet the code requirements in order to experience their shortcomings and reinforce designers' knowledge of the code requirements [20].


### 2.4. Emphasis on Building Structure and Construction Techniques

Currently many designers do not consider their designs from a construction point of view, nor from a practical use point of view, and the building design is often just an empty box, with sections only looking for the simplest and best drawn sections, symbolically expressing the position of beams, slabs and columns [21]. The traditional teaching system allows designers to understand the construction of buildings only through classroom lectures and pictures. The combination of virtual reality software and BIM models allows for a realistic teaching model, showing designers the animation of the building assembly process and combining theory with practice. Most designers only consider which materials or colours to use in general, but few consider the size or modulus of the specific materials to be used. Virtual reality allows designers to experience the texture and effect of the material from a human point of view, improving the details of the building [22].

## 3. Digital Museum Dynamic Panoramic Virtual Display System

### 3.1. Overall Structural Design

The Digital Museum Dynamic Panorama virtual display system consists of a viewer and object database management module, a digital museum design module and a digital museum viewing module, see Figure2.Figure 2
Architectural framework of the digital museum dynamic panoramic virtual display system.In Figure2, the main function of the viewer and the object database management module is to correct, add and delete objects in the MySQL database and FTP server; the main function of the digital museum design module is to access the information of the objects for viewing, download the information from the MySQL database and FTP server to the local area, and the viewer sets up the two-dimensional floor plan of the digital museum according to their needs. The viewer sets up a 2D floor plan of the digital museum according to their needs and then builds a VM model file [23]; the digital museum viewer module analyses the VM model file and displays a dynamic panorama of the digital museum that has been built.


### 3.2. Digital Museum Design Module

The digital museum design module ensures that the viewer is provided with a list of objects available in the database according to the viewer level after successfully logging into system. A 2D plan of the digital museum is generated in the drawing board and images are selected from the local plan as textures for the different areas of the digital museum. The objects listed in the object information list are placed in the 2D plane of the digital museum display system and a VM file is generated, as shown in Figure3.Figure 3
Digital museum design module.The information stored in the VM file includes: the number of vertices and the location of the different vertices in the 2D plan of the digitised museum; the number of objects, their IDs and their locations in the digitised museum; and the initial position of the viewer set in this module.


### 3.3. Digital Museum Navigation Module

The main function of the digital museum viewer module is to analyse the VM file in the digital museum design module, stretch and change the 2D plan view in the digital museum design module into a 3D spatial view [24], and provide the viewer with the viewer, as shown in Figure 4.Figure 4
Design of the digital museum browsing module.The VM file containing information about the digital museum is accessed through the Digital Museum Design module, and the VM file is opened through the Digital Museum Browser module to access the information contained in the digital museum. Within the digital museum display system, the viewer is able to roam through the VM file using the keyboard [25].


### 3.4. Software Design

#### 3.4.1. Digital Museum Technology Building Process Design

The need of the viewer is fundamental to a digital museum display system. In order to meet the needs of the viewer, the technical construction process of the digital museum is based on display design, human interaction theory and visualisation techniques, as shown in Figure5.Figure 5
Digital museum technology building process.Theme identification and requirements analysis phase focuses on a comprehensive analysis of the theme of the digital museum display system. The need and feasibility of the theme is studied, and the system structure is comprehensively planned based on the theme, while the ultimate functions and objectives of the digital museum are defined. The overall architecture design phase is based on the results of the previous analysis and defines the overall framework for the scenarios, presentation methods and functional objectives of the digital museum. The 3D modeling software is used to construct the planned museum scene and the required models, set the lighting and materials and other performance effects, and obtain a realistic browsing experience. The interactive visualisation phase imports the completed museum scene and model into the interactive visualisation software and optimises it for high-quality interactive visualisation. Once the visualisation has been implemented, the museum visualisation is exported as a web page or an executable file and published on the corresponding website [1].


#### 3.4.2. Tag Cloud Component Design

A collection of weighted tags, known as a tag cloud, reflects the differences in tag weight based on differential fonts and other visualisation, and viewers use tags to connect to relevant information. The tag cloud component is used in the display system, where tags are constructed by viewers and experts, and the topics and categories of information are presented through tags, which are used by viewers to obtain information related to the topic. The font size in the tag cloud component is based on tag weight. The number of tag visits describes the tag weight and the difference in font size reflects the information that is more frequently viewed.The Tag Bean Java class, which stores information such as tag name, builds time and tag link, stores the tag topics and their corresponding Tag Bean objects in a HashMap, data type included in Java. The core of the Tag Cloud component is how to scientifically map the number of tag clicks to the differences in tag fonts. The number of clicks on all tags in the database is unevenly distributed, similar to a normal distribution. The system uses a linearisation algorithm to calculate the number of clicks in order to distribute the number of user clicks evenly across the foot variance interval, as follows：(1)E=∑i=1,2,…,mhitNumi−meanNum2m,(2)W=maxSize−minSize4E,(3)FontSizei=WhitNumi−meanNum+midSize,where: E, W and FontSizei are the average difference in label clicks, linear slope and label i font variance, respectively;, and meanNum are the number of clicks on label i, the total number of labels in the database and the average of all label clicks, respectively; maxSize, minSize and midSize are the maximum value of the label font variance interval, the minimum value of the label font variance interval and the middle value of the font variance, respectively and the middle value of the font difference.The first step in the calculation process is to determine theE of the total number of tag clicks; the deviation error of the total number of tag clicks is obtained by aggregation from -2E to 2E, and W is determined by equation (3); on this basis, the font difference value of tag i is determined using the values of meanNum and midSize, etc.
