1. Introduction
A 360° virtual tour is analogous to Google Street View (GSV) for both indoor and outdoor environments. A series of 360° photographs are linked together to allow the online user to virtually ‘walk’ around and discover more about the surrounding spaces than using typical photographs. Using a mobile device, tablet, desktop, or virtual reality goggles, a user can navigate through the tour by simply clicking on ‘hot spots’ within the 360° panoramic photo.
The history of 360-panoramic tours can be traced back to the mid-1990s when the first virtual tour software was developed [1]. At that time, the technology was limited to static panoramic images that could be stitched together to create a 360-degree view of a particular location. With the advent of high-speed internet and advances in camera and software technology, it became possible to create more immersive and interactive 360-panoramic tours [2,3]. A 360° virtual tour provides a unique immersive sensation of “being there” and builds trust and confidence for remote visitors, helping them to interpret the site remotely and hopefully compel them to organize an eventual physical visit/tour [4,5,6].
That said, the 360-pano tour or 360-VR is not true ‘virtual reality’ [7] as it does not support the freedom of movement inside the virtual space and limits the visitors/users to moving only from one point to another point, predicated on where the photo was taken. A pano tour is a good option for applications requiring wider audience reach, more cost-effectiveness, or flexibility, while VR tours are more suitable for applications requiring a higher degree of immersion and interactivity.
The COVID-19 pandemic has had a significant impact and has boosted the use and popularity of 360 VR tours. Studies from Sarkady et al. [8] and Rahim et al. [9] show that, while travel and in-person events have been restricted in many parts of the world, businesses and organizations have turned to virtual experiences to reach their audiences. Subsequently, 360-degree panoramas have appeared as an effective tool for providing immersive and interactive experiences for cultural heritage, tourism [10], and in particular for real-estate visualization [11].
Research has focused on the technical aspects of creating 360-pano tours, such as the use of different camera systems [12] and free stitching software to create high-quality panoramic images [3,13]. Other research has focused on the impact of different design and user interface elements on the effectiveness of 360-pano tours [5,14,15,16]. However, irrespective of their popularity and wide usage, we rarely find studies that compare feature lists of 360-degree pano tour-making software and services; instead they are focused on evaluating the effectiveness of specific software or services for creating and hosting 360-pano tours. Furthermore, it is rare to find papers presenting detailed workflows for developing interactive 360-pano tours, especially with embedded information for more in-depth interpretation.
This paper begins with an in-depth comparative analysis of some popular software and online services available for creating 360-pano tours. Following this, it outlines a comprehensive, step-by-step workflow for developing an interactive 360-panorama tour, using the significant heritage site of the Subiaco Hotel in Perth, Australia as a case study. This study incorporates various interactive features supported by the selected software or tools, embedding relevant information and data to enhance the user’s interpretation and overall experience. As a result, a functional prototype of a multimodal 360-pano tour [17,18] is showcased and examined. Subsequently, the paper delves into the insights and feedback provided by a small group of general users, enriching the understanding of the technology’s implications in this context. Concluding the study, this paper outlines potential future research directions and development guidelines, paving the way for continued innovation and improvement in the realm of 360-pano tours.
2. Background
In the heritage sector, 360-panorama tours (often referred to as 360-pano tours or 360-VR) are a form of immersive technology enabling users to explore a virtual space using 360-degree photographs of a location that are linked together. Users can interact with hotspots within the photos and access additional information through annotations such as text, images, audio, and video. These tours offer a more immersive experience than Google Street View and have potential uses for interpreting heritage buildings and sites.
In this section, we provide an overview of previous studies and research on 360-panorama tours. We conducted a comparative study of different 360-panorama tour software and services and discussed their prominent features and uses with a particular emphasis on heritage interpretation and visualization. Overall, this section aims to provide a comprehensive and up-to-date understanding of the 360-panorama tour landscape, as well as offer key considerations for those looking to utilize this technology in their work.
We do, however, caution that the features listed in the tables are not a comprehensive assessment of all the available options. Additionally, some software may have additional features not listed in the tables or may have been added since the time of our study.
2.1. Overview of Previous Studies and Research
The use of 360-panorama tours in the field of heritage interpretation has received growing attention in recent years, with numerous studies and research projects exploring the potential of this technology. Zeng et al. [5], El-Said et al. [16], and Kim et al. [14] explored the effectiveness of virtual heritage in engaging visitors and enhancing their learning experience, using 360-panorama tours as a case in point. Similar studies have been carried out by various researchers [19], [20] and [21] in museum settings, comparing the use of 360-panorama tours with traditional methods of interpretation, such as audio guides and static images. Shadiev et al. [22] found that virtual reality and 360-degree video applications in cultural tourism increased tourists’ experiential value and satisfaction. Studies [5,12,16,23,24] also suggested that 360-pano tours can be an effective tool for increasing access and engagement with heritage sites.
Authors such as Gafar et al. [25], Barkatov et al. [26], Shadiev et al. [22], and Pereira et al. [27] studied various software and online services in creating 360-panorama tours while exploring their accuracy and usefulness in providing up-to-date information about heritage sites. In most cases, these studies showcase and highlight the positive impact of 360-panorama in delivering valuable insights into better interpretation and engagement of the site [5,24,26,28]. We can also find various studies and reviews of current practices and the exploration of the potentials of some tools [10,22,25], while authors such as Shadiev et al. [22] and Gafar et al. [25] have reviewed the current research on 360-panorama tours.
Studies from Shehade et al. [29], Koehl et al. [30], and Boukerch et al. [3] have described the design and development of a 360-degree panoramic virtual reality system for heritage tourism that links a database of historical information with a 360-panorama tour of a heritage site. However, these studies mostly focused on ensuring the validity of the information rather than reporting any user experience [31] or presenting an optimized workflow. It is rare to have studies presenting a comparison of 360-pano tour software and services and presenting a comprehensive workflow for building interactive 360-VR tours for historic sites in one place. There is also limited research on user feedback and a paucity of useful showcases of audio, video, text, 3D-models, and photos integrated within the 360-panoramic tours.
2.2. The Current State of 360-Panorama Tour Technology and Software
A 360-panorama tour is a popular way to experience virtual tours of various places, including heritage sites and buildings. The technology behind 360-panorama tours involves capturing 360-degree photos and linking or embedding them with data to create an interactive tour experience.

2.3. Comparative Study of 360-Panorama Tour Software and Services
To have a clear understanding of the current offerings, we undertook an intensive online search and selected 50 candidates (desktop software and online services) and listed their origin and web address (Table 1). Data from Table 1 gives a snapshot of the 360-degree technology industry and its geographical distribution. Most of the companies are from the United States (14), followed by the UK (4), Canada (4), Spain (2), and other countries (25). This highlights the global reach and popularity of 360-degree technology. Our study also indicates that several companies specialize in particular domains, such as furniture and kitchen visualization (3DCloud), architectural visualization (iGuide), and large infrastructure inspection (OcuMap). Some companies offer services to whole tours by professionals (Paneek) and BIM support (CUPIX).
Next, we selected twenty popular online-based 360-pano tour development and hosting services from Table 1 and listed their offered features and prepared a comprehensive database in Table 2. To conduct the selection, we reviewed user feedback and ratings from diverse platforms, including review websites, forums, and social media. This analysis allowed us to gauge the satisfaction levels and reputation of the shortlisted software solutions. Furthermore, we conducted a comprehensive comparative analysis of the features, functionalities, and capabilities of the shortlisted services. This evaluation enabled us to identify the top twenty software solutions that excelled in meeting our criteria. Table 2 includes the following platforms: Matterport, Orbix360, Kuula, RICOH360, Klapty, Concept3D, CloudPano, My360, EyeSpy360, Virtual Tours Creator, Floorfy, Metareal, Panoroo, WeboBook, TourWizard, Lapentor, TeliportMe, Real Tour Vision (RTV), EvryPlace, and VTILITY.
Table 2 showcases a vibrant ecosystem of solutions catering to a broad spectrum of user requirements and budgets. Many of the platforms support common image formats such as JPG, PNG, and BMP, but there are some differences in the types of 360-degree images that are supported. ORBIX360 stands out for supporting stereoscopic/3D images, while CloudPano supports animated GIFs and MP4 videos. Both Matterport and Kuula support an extensive range of image formats, and are compatible with a variety of 360 cameras, including popular models such as the Ricoh Theta and Insta360.

Additionally, users can incorporate floor plans and contact information, giving potential clients a comprehensive understanding of the property or location being showcased.
Many virtual tour platforms offer a range of additional features, such as hotspots (interactive elements that users click on to access more information or navigate to different areas within a virtual tour), floor plans, and virtual staging (digitally furnishing and decorating empty spaces or existing rooms in a virtual tour to make them visually appealing and help viewers envision the possibilities). When choosing a platform, it is important to consider which features are most valuable for your needs. Custom branding (incorporating a company’s or individual’s brand elements into the virtual tour to maintain a consistent brand identity and create a professional look) and white-labelling (removing or replacing the default branding of the virtual tour software or platform with the user’s own branding for a customized appearance) options, for example, are available with software such as Concept3D, enabling users to tailor the appearance of their virtual tours and host them on their own domains. Virtual staging services, provided by platforms such as Klapty, allow users to digitally furnish spaces, helping potential buyers or renters to visualize the possibilities. Interactive floor plans, offered by CloudPano and Floorfy, enhance spatial understanding while leading generation tools from Real Tour Vision and Virtual Tours Creator capture viewer contact information. Custom hotspots, as featured in Metareal and Lapentor, enable further exploration within the virtual tour, while live virtual tours, such as those offered by EyeSpy360, provide personalized experiences even when in-person visits are not possible.
Advanced features such as dollhouse views (3D representations of the entire property or area, providing a unique perspective by displaying the structure as if it were cut open, allowing viewers to see the spatial arrangement and layout) and measurement tools are also available on some platforms, further elevating the virtual tour experience. For instance, Matterport’s 3D dollhouse view provides users with a unique, interactive perspective of a space, while platforms such as Zillow 3D Home include measurement tools to help users gauge the dimensions of rooms and objects accurately.
Export file formats are diverse among these platforms, with many of them supporting HTML5, direct links, embed links, and social media sharing options. This flexibility allows users to share their virtual tours in multiple ways, increasing their reach and engagement. The majority of these platforms are compatible with a wide range of devices, including smartphones, tablets, and computers, ensuring that users can access, create, and share their virtual tours seamlessly across multiple platforms. This cross-device compatibility is crucial in today’s interconnected world, as it allows potential end users to explore virtual tours anytime and anywhere.
It is also evident from Table 2 that the fees charged by the virtual tour software vary greatly, ranging from $0/month to $333/month. For example, Virtual Tours Creator charges $19.99/month for its self-capture plan, while Real Tour Vision (RTV) charges $219 for its Software+10 credits plan. Similarly, fees for hosting services also vary, with some software providing a limited amount of storage for free, while other charges are based on the amount of storage used. For instance, CloudPano offers a basic package at $37 per month (while writing this paper), making it accessible to smaller businesses and individual users, while Concept3D’s pricing starts at $1,500 per year, catering to larger enterprises or more demanding use cases. In conclusion, the pricing and hosting service offered by virtual tour software depends on the specific software, and the needs and budget of the user should be taken into consideration when choosing a virtual tour software.
Similarly, we included eight popular desktop-based software candidates, i.e., 3DVista, Pano 2 VR, PanoramaStudio, Revvis, Envisioneer, Glo3D, Krpano, and Tourweaver, in Table 3, which provides a comprehensive comparison of various virtual tour software platforms, highlighting their general features, pricing, and capabilities.
All software programs support most camera types. In terms of supported file formats for importing, 3DVista can import JPG/JPEG, PNG, BMP, TIFF, and GIF files, as well as Live Panoramas and Adaptive HDR. Pano 2 VR supports JPEG, PNG, TIFF, PSD/PSB, OpenEXR, RGBE, MP4, and MOV. Besides JPG, TIFF, BigTIFF, PSD, BMP, PNG, and WEBP, PanoramaStudio 3 claims that they support more than 1180 RAW formats.
Regarding projected file formats, 3DVista supports 18 types, including equirectangular, cubic, rectilinear, cylindrical, fisheye, Mercator, and Albers equal area conical, among others. Pano 2 VR supports flat, cylindrical, spherical, perspective, stereographic, and fisheye projections. PanoramaStudio 3 supports cylindrical, spherical, and perspective projections. Revvis provides a first-person view, 3D view, plan view, and VR headset view. Krpano and Tourweaver do not provide enough data on projected file formats.

Furthermore, linking a database with a 360-panorama tour highlighted the importance of providing rich and context-specific information to enhance the user experience. However, it is important to scrutinize the ease of use, scalability, and compatibility of these methods with various software and platforms.
The 360-panorama tour technology and software landscape presents a wealth of opportunities for creating captivating virtual experiences. Nevertheless, it is essential to critically examine the offerings, their accessibility to different user groups, and the potential for further innovation and collaboration to drive the industry forward and ensure that the technology’s full potential is realized.
3. Methodology
3.1. Site Selection
This study is part of a larger project, the Australian Cultural Data Engine (
Our goal was to showcase the usefulness of panorama tours in presenting the spatial and chronological context of buildings and interiors through the integration of different media with 360-degree photographs. Digital panoramas can integrate and juxtapose different media and sources, as well as more intuitively and immersively link spaces, be they interior spaces or exterior ones, with various modes of cultural data. This may be of particular use in displaying spatial media from different eras in more quickly understandable chronological and spatial contexts.
Given the above, the Subiaco Hotel in Perth is the perfect choice for our project on the impact of 360-pano tours on heritage understanding and preservation. This iconic heritage building, built in the 1890s and designed by Summerhayes Architecture, holds great cultural and historical significance [41]. The hotel was built in the late 19th century and is one of the oldest remaining buildings in Subiaco, an inner-city suburb of Perth. The hotel was designed in the Federation Free Classical style, which was popular in Australia during the late Victorian and Edwardian eras. This style is characterized by classical architectural elements such as columns, pediments, and balustrades, combined with decorative features such as stained glass and ornate plasterwork. The Subiaco Hotel’s architectural style is widely recognized and praised by experts in the field, making it a noteworthy example of its kind. The hotel’s historical significance and unique design contribute to its significant heritage value, making it an important cultural landmark in Perth [42].
In addition to its architectural significance, the Subiaco Hotel is also historically important. The hotel has been in continuous operation since it was built (in 1897 or earlier) and has played a significant role in the social and cultural life of the local community. It was a popular gathering place for residents and was known for hosting events such as dances, parties, and other social gatherings. In 1994, the Subiaco Hotel was officially recognized for its cultural and historical value when it was listed on the Western Australian Heritage Register [43]. This designation highlights the building’s importance as a symbol of Perth’s rich heritage and recognizes the need to preserve its original form and protect its significance for future generations.
3.2. Documentation with 360 Photography
The documentation of the Subiaco Hotel in Perth, Western Australia, was carried out using 360-degree photography and the Theta X camera. The camera was set to HDR mode, which allowed for the capture of a broader range of light and color, providing vivid and detailed images. The time-shift mode provided by the software was utilized to eliminate the presence of the photographer in the photos. This mode was convenient for the documentation process as it allowed for the creation of panoramic images without any obstructions. However, the time-shift mode had a drawback, as it only produced internally stitched JPEGs, and no raw files were produced. This limitation restricted the options for color correction during post-processing and could have impacted the final quality of the images.
Despite the limitations of the time-shift mode, over fifty 360-degree panoramic photos of both the interior and exterior of the Subiaco Hotel were created. This comprehensive set of images provides a thorough visual record of the building’s architectural and cultural significance and necessary information for the next step.
3.3. Post-Processing
The post-processing of the 360-degree panoramic photos of the Subiaco Hotel was a crucial step in ensuring the visual quality and accuracy of the final product. A total of over 50 photos, both interior and exterior, were taken using a Theta X camera with HDR mode enabled. The camera generated jpeg images with a resolution of 11,008 × 5504 pixels and 200 DPI. The post-processing of these images involved 5 key steps, including color correction, NADIR/tripod removal, denoising, up-scaling, and final export in a pano tour compatible format with Exif data.
The photos were first transferred to a computer using the camera’s native software, ’Ricoh Theta File Transfer for Mac’. The initial step of post-processing was performed using Adobe Lightroom, where the photos were white-balanced and color-corrected, and necessary adjustments were made to exposure, highlights, dehaze, and vibrance. In the next step, the photos were taken to Adobe Photoshop for NADIR correction, which involved manual patching and export of each photo as a jpeg image.
To remove the significant noise present in the images, the photos were then processed using Topaz’s Denoise software in standalone mode with the standard AI model and manual adjustments. The processed images were then up-scaled to 8K resolution (16,384 × 8192 pixels) using Topaz’s GigaPixel software, where the Standard AI model (default) with some sharpness was applied. Finally, the photos were imported to Adobe Lightroom again, reduced by 20% in size, and exported as jpeg files. We found this setting significantly reduces the file size of the panoramas while making any noticeable impact on the color and quality with naked eyes.
The image editing process was carried out systematically, and Figure 1 demonstrates the steps involved in the process. This comprehensive post-processing approach ensured that the final product was of the highest quality and accuracy, providing a visually stunning interpretive 360-pano tour of the heritage-listed building, the Subiaco Hotel.
3.4. Selection of the 360-Pano Tour Development Software
In our study, the selection of the 360-pano tour development software was a critical aspect, driven by our specific goals of creating an interactive tour of a significant heritage site and demonstrating the seamless integration of various media elements such as text, video, audio, and 3D models to enhance the user’s interpretation and experience.
After conducting a thorough evaluation, we identified 3DVista as the preferred software solution due to its exceptional features and capabilities. Firstly, the offline working option offered by the platform allowed us to create and edit virtual tours without the need for an internet connection. This flexibility greatly facilitated our workflow. Furthermore, the ability to export tours as executable files simplified the sharing and distribution process, ensuring widespread accessibility. 3DVista’s support for 3D model integration was another compelling factor, enabling us to showcase linked 3D models from Sketchfab within our virtual tours. Additionally, the software provided features such as ‘virtual staging’, allowing us to illustrate thematic changes in the space over time, further augmenting the tour’s narrative and helping to showcase the historic value of the building.
The capability of creating customized hotspots and pop-up information windows within 3DVista was invaluable. These interactive elements help to provide additional context and details and can foster exploration and deepen user understanding of the heritage site. Additionally, the one-time purchase model and bundled feature set offered by 3DVista not only provided significant value but also resulted in cost savings, making it an appealing choice for our study.
By combining a one-time purchase model with extensive features, including offline working capabilities, export options, 3D model integration, virtual staging, custom hotspots, and pop-up information windows, 3DVista proved to be an excellent solution for creating high-quality virtual tours for our project.
3.5. Interaction Design and Development of the VR Tour
3DVista allows both stitched and unstitched images. As we have already prepared the stitched images, there are five basic steps to develop the interactive tour with 3DVista, i.e.:
3.5.1. Import the Stitched Images into 3DVista
The import function in 3DVista allows adding various types of media files to a project, such as panoramic photos, regular photos, videos, audio files, and more. To import stitched images into 3DVista, click on the “Import" button and select the panoramic image file. User should note here that the photos need to be in the form of equirectangular or cubemap images with a 2:1 aspect ratio. Supported file types include JPG, PNG, and TIFF. 3DVista can also import audio (MP3, WAV, and OGG), video (MP4, AVI, and MOV), and 3D models (OBJ, FBX, and DAE).
3.5.2. Add Hotspots
Hotspots are interactive elements that link different panoramic photos together to create a seamless navigation experience. They also allow users to click on different parts of the panorama and explore them in more detail. By clicking on the “Hotspots” button and selecting the type of hotspot, it is possible to add text, images, videos, and other multimedia elements to the hotspots, and also customize their appearance, behavior, or properties. By using hotspots creatively, one can enhance the visual storytelling of the tour and guide the audience through it. Adding hotspots can make the 360-pano tour more engaging, interactive, and memorable for the audience.
3.5.3. Customize the Tour
Customizing the tour in 3DVista is an important step to enhance the user experience and create a unique 360-pano tour. First of all, we added text, images, and other multimedia elements to the tour hotspots to allow additional information, such as descriptions, captions, 3D models, and multimedia content, to enhance the user’s understanding and enjoyment of the tour. We also added background music to set the mood of the tour and tried to offer a more immersive experience. Moreover, we customized the tour’s appearance and style by using specific themes, color schemes, and layouts.
3.5.4. Preview Your Tour
The preview phase is an important step in creating a 360-pano. During this phase, we previewed and tested the tour to ensure that everything works as expected and that the user experience is optimal. Clicking on the “Preview” button in the toolbar opens a new window that shows a live view of the tour. From there, it is possible to navigate through the tour, test the hotspots and multimedia content, and make any necessary adjustments. Preview mode also allows the testing of the tour on different devices and platforms to ensure that it is optimized for different screen sizes and resolutions and cross-browser compatibility.
3.5.5. Publish the Tour
Exporting a 360-panoramic tour from 3DVista is a straightforward process that involves converting the tour from the software format into a format that can be easily viewed and shared. 3DVista allows publishing the tour as a standalone executable file or as an HTML5 file, or uploading it directly to a website, to YouTube (360 videos), or the 3DVista cloud hosting service. The standalone executable file (.EXE for PC and .Dmg for Mac) allows the distribution of the tour as a standalone application that can be downloaded and installed on a computer. This file type is suitable for offline use and can be customized with its own branding elements. On the other hand, the HTML5 file (.html) allows the publishing of the tour online and sharing it with audiences via a web browser without requiring any download. 3Dvista also allows uploading the tour directly to a website using FTP or a web hosting service.
4. The Prototype
For the prototype development, we utilized 10 panoramic photos (out of 50) to create a comprehensive tour that integrates various information and media files, including text, images, drawings, PDFs, audio, video, and 3D models.
Upon accessing the virtual tour online or through the executable file, viewers enter the tour at the main entry point of the Subiaco Hotel. The user interface features a left-side menu with options such as Panoramas, Background, Major Changes, Original Drawings, Resources, and Street Views, all of which are self-explanatory. Additionally, five icons are located in the bottom-right corner, providing users with options to enable HMD mode, toggle sound on/off, view drawings, enter full-screen mode, and access details (Figure 2).
By clicking on the animated icon on the floor or selecting any hotspot icons, viewers can begin navigating the tour and move from one space to another. The floating icons or hotspots are self-explanatory and connected to relevant data and digital resources. For instance, clicking on an icon representing a link, PDF, video, 3D model, or image will open a pop-up window, displaying the associated data and information (Figure 3). In this prototype, video and 3D model content are dynamically linked via YouTube and Sketchfab, while other files and data, such as info, photos, and PDFs, are hosted locally. Please note that as a consequence of logistical issues during the prototype’s development, we could not obtain digital copies of the original drawings and images; therefore, similar old drawings and photos have been used as placeholders.
The left Panoramas button opens a slider displaying the 360-degree photos used for this tour. Users can navigate and jump directly to a specific point by clicking on the corresponding photo (Figure 4a). The Background button opens a pop-up window showcasing the hotel’s history, accompanied by sliding/animated old photos (Figure 4b). Similar to the Panoramas button, the Original Drawings button unveils another slider, so that users can click on thumbnails to enlarge specific images or drawings. The Resources button, on the other hand, opens a media gallery containing 3D models, videos, audio files, PDF files, and photos. Each group opens new windows, showcasing their respective libraries (Figure 4c, 4d, 4e). For example, Figure 4c shows the 3D gallery and its respective library, where the 3D contents are pulled/linked from Sketchfab’s depository. The Street View button transports the user to Google Street View, enabling them to explore the surrounding streets and observe the building within its historical context, providing a better understanding of the streetscape (Figure 4f).
One of the most captivating features of this pano tour is the interactive visualization of the building’s thematic changes over time, which can be accessed through the Major Changes button. Clicking on this button transports the viewer to a specific location within the hotel and a date slider appears on the right side of the interface (Figure 5). Viewers can select a date/time to see the changes that occurred in that space/location over time. The installed items/materials will be highlighted (colored), while the remainder will be greyed out. Simultaneously, the viewer can move, zoom, and rotate the view in 360 degrees. This will assist the viewers in interpreting the historical significance of the building while knowing the authenticity vs intrusiveness of the building materials and installations over time. (Please note that the changes are not historically authentic and are created only to serve as a proof of concept).
In conclusion, the prototype developed for the Subiaco Hotel virtual tour offers a comprehensive and interactive experience that effectively integrates various information and media files. The user interface is intuitive and user-friendly, with self-explanatory menus and icons that guide viewers through the tour. Hotspots seamlessly connect the viewer to relevant data and digital resources, while various buttons provide quick access to panoramas, background information, original drawings, and other resources. The interactive visualization of the building’s thematic changes over time is a particularly captivating feature that enhances the overall experience. Although the prototype has some limitations, such as the use of placeholder images, it serves as a solid proof of concept, demonstrating the potential for a truly immersive and informative virtual tour.
However, during the exporting process, we encountered compatibility issues and occasional software crashes. Sometimes, incorrect export settings resulted in poor resolution or large file sizes, leading to a lower quality tour or to longer load times. If hotspots or linked scenes are not properly set up, they may not work as intended when the tour is exported. Software glitches can also cause the tour to crash or prevent it from being exported correctly. Lastly, the exported file size is another issue, as it may take too long to load or be inaccessible on certain devices. We are currently working on fixing and improving these issues.
Overall, it is crucial to carefully preview the tour and test it thoroughly before exporting to ensure that all elements are functioning as intended. If any issues are encountered, they should be addressed before the tour is exported to minimize the risk of problems when it is published.
5. Discussion
This study aimed to develop an interactive 360-pano tour while presenting an optimized workflow and at the same time providing feedback on the suitability of these interpretive tours for a richer understanding and appreciation of historical sites and for improved decision-making by heritage professionals and associates.
5.1. Software Is Evolving with New Features
The 360-pano software landscape has undergone significant advancements in recent years, fueled by the rapid progress of new technologies and the growing demand for immersive experiences [12]. These advancements have led to improved image quality and resolution, facilitated by state-of-the-art camera technology and advanced image processing algorithms [26]. A comparative study of 50 desktop software and online services catering to various needs and skill levels found that each platform possesses unique strengths and weaknesses. To stay competitive, these platforms are continuously evolving and frequently introducing new features. While professional photography software such as Adobe Photoshop and online platforms such as Google Street View, RoundMe, and Kuula offer diverse options for different needs and skill levels, the quality of the resulting tour can vary based on the platform used.
The incorporation of depth information and 3D mapping has further enriched the realism and spatial awareness in 360-pano tours [44], while the integration of laser scanning technologies and 360º photography enables more accurate digital documentation [45]. Additionally, the application of artificial intelligence (AI) streamlines the stitching process [46], and the use of NeRF (Neural Radiance Field) models assists in developing scene geometry from 360-panoramas. These emerging developments suggest that 360-pano software will continue to deliver increasingly sophisticated and engaging virtual tours in the future.
5.2. Comparative Study and Finding the Best Solution
The 360-panorama tour industry presents a diverse array of software and platforms designed for creating and hosting immersive virtual tours. Our comprehensive study of 50 desktop software and online services catering to various needs and skill levels highlighted that each platform possesses unique strengths and weaknesses, emphasizing the importance of the careful evaluation of specific requirements to select the most suitable solution.
Our investigation uncovered numerous desktop software and online services targeting different needs and skill levels, with specialized companies focusing on niche areas such as furniture and kitchen visualization, architectural visualization, and large infrastructure inspection. It is evident that VR and 360-degree technology have a global reach, with the majority of companies based in the US, followed by the UK, Canada, Spain, and other countries. This study also demonstrated that pricing, hosting services, and features, including multimedia content integration and tour customization, vary depending on the chosen package or service. A thorough assessment of individual requirements is crucial for selecting the most appropriate platform. Furthermore, despite the global expansion of VR and 360-degree technology, occasional bugs and glitches may still affect the final quality and export of the 360-panorama tour.
It is important to note that our findings are based on the features listed in Table 2 and Table 3 during our survey for this paper and may not provide a comprehensive assessment of all available options. Furthermore, more recent software updates may have added new features that were not available at the time of our survey (last quarter of 2022).
5.3. Issues Regarding 3DVista
While 3DVista offers a range of advanced features, users should consider technical limitations, file management, customer support, and competition from other software options. One advantage of 3DVista is its user-friendly interface, which allows users to easily create and customize their tours. The software also offers various multimedia options for enhancing the tour experience, including the ability to add audio, video, and other interactive elements to hotspots, as well as customization options for tour design such as changing the background music, tour speed, and overall appearance.
However, when using 3DVista for creating 360-panorama tours, users should be aware of file management challenges. Each project can generate a large number of files, including individual images, audio files, and other multimedia elements, so users need to have a plan in place for organizing and backing up their files to prevent confusion and loss of data. Bugs may also create issues for the software’s rendering capabilities, alignment issues between individual images, and other technical issues that can impact the final quality and export of the 360-panorama tour. Users should be aware of these potential issues and stay up-to-date with software updates and bug fixes to ensure the smoothest possible experience. It is also important for users to regularly save and back up their work to avoid the loss of data in the event of a software malfunction.
5.4. User Feedback
The prototype was demonstrated to a small group of colleagues in the area and their general user feedback was collected. Overall, users had a positive impression of the 360-panoramic tours of historic buildings. They found the tours engaging and valuable as educational and interpretative tools, which helped enhance their understanding and appreciation of the structures.
Moreover, users appreciated the opportunity to experience the buildings more personally, and to be able to view historical artefacts or scholarly arguments in spatial and chronological context through the integrated information (photo, video, 3D, etc.) into panoramas of the existing building framework. Having a detailed view of a specific object with a zooming option impressed them. They also viewed the tours as effective tools for the conservation and promotion of historic buildings, highlighting the potential to raise awareness about the importance of preserving such structures while encouraging general people to actively participate in their protection and conservation. Nevertheless, users identified several critical aspects and issues, including:
Lost in space: There was no help or tutorials. They asked for a dollhouse or navigation plan/map views where they can locate themselves in the map.
Technical limitations: Slow loading times were reported by some users, which negatively affected their experience.
Lack of interactivity: A few users criticized the passive nature of the experience, noting that the level of interactivity and freedom of movement was limited compared with Virtual Reality.
Inaccuracies: Some users pointed out inaccuracies in the information presented in the 360-panoramic tours, such as the use of mock or placeholder images instead of original photos and media.
Limited accessibility: The 360-panoramic tour was restricted to ten spots; most of the users wanted a more comprehensive tour of the entire building.
Despite these criticisms, the 360-panoramic tour of the historic Subiaco Hotel was generally well-received by users. They found it to be a valuable educational tool that helped enhance their understanding of the history and significance of the building.
5.5. External Data Integration
Incorporating external data into 360-panoramic tours of heritage buildings necessitates striking a balance between delivering valuable information and preserving the immersive nature of the tour. Our study was limited by the features of 3DVista and the data integration options provided by the platform/software. Although there may be alternative methods for integrating external data, such as API, embedding databases, or CSV integration, these approaches often require advanced programming and technical skills.
The quality and relevance of the external data play a pivotal role, as low-quality or unrelated information may diminish the overall experience. Furthermore, accessibility factors, such as audio descriptions or subtitles, must be taken into account. While external data can enrich users’ understanding of the building and its history, an excessive amount of information may overwhelm them and detract from the immersive quality of the tour. As a result, careful consideration and planning are essential for the successful integration of external data into 360-panoramic tours of heritage buildings, ensuring that the tour remains informative and enjoyable for all users, regardless of the integration methods employed.
