Augmented Reality (AR) Maps for Experiencing Creative Narratives of Cultural Heritage
(The Eurographics Association, 2019) Echavarria, Karina Rodriguez; Dibble, Laurie; Bracco, Aurelie; Silverton, Edward; Dixon, Sophie; Rizvic, Selma and Rodriguez Echavarria, Karina
This research investigates how communities can meaningfully connect with Cultural Heritage through creative and digital experiences. It also explores how entry barriers can be lowered for a wider set of audiences to increase their participation in such experiences. For this, the research investigates the use of creative and narrative-based approaches, given the potential for stories to illuminate different viewpoints and interpretations of Cultural Heritage. The paper's main technical contribution is a novel approach for re-telling communities' narratives linked to people, objects, sites and events in the urban landscape as told by the community. The research proposed the novel concept of Augmented Reality (AR) Maps, which are physical maps with augmented digital narratives and delivered through Immersive Web technology. This concept is proposed as a means to document and disseminate the narratives in a way which can enhance the public understanding and appreciation of objects and sites in their communities. The approach has been tested with 32 children in local primary school in the city of Brighton and Hove (UK) in order to understand its suitability for community engagement. The significance of the research is that it demonstrates the potential of both creative and digital approaches for enabling meaningful engagement with the Cultural Heritage, while improving the well-being of the participants as well as their sense of community and place.
Digital Workflow for Creating 3D Puzzles to Engage Audiences in the Interpretation of Archaeological Artefacts
(The Eurographics Association, 2018) Echavarria, Karina Rodriguez; Samaroudi, Myrsini; Sablatnig, Robert and Wimmer, Michael
3D physical puzzles are typically used to engage audiences in the interpretation of archaeological artefacts in a museum exhibition. The reason for this is that a puzzle can be seen as a game but also as a complex activity that archaeologists undertake to re-assemble fragments. The contribution of this paper is a novel digital worfklow for the design and fabrication of 3D heritage puzzles. The input to the workflow is an authentic artefact from a heritage collection, which is then digitised using technologies such as 3D scanning and 3D modelling. Thereafter, a puzzle generator produces the 3D puzzle pieces using a cell fracture algorithm and generates a set of puzzle pieces (female) and a single core piece (male) for fabrication. Finally, the pieces are fabricated using 3D printing technology and post-processed to facilitate the puzzle assembly. To demonstrate the workflow, we deploy the proposed method to create a 3D puzzle of an artefact, the Saltdean urn, for the Archaeological Gallery of the Brighton Museum and Art Gallery. The significance of this research is that it eases the task of creating puzzle-like activities and maintaining them within a busy museum gallery.
Experiencing Art by Means of 3D Printed Replicas: Enriching the Interpretation of Pot Oiseau
(The Eurographics Association, 2019) Samaroudi, Myrsini; Echavarria, Karina Rodriguez; Rizvic, Selma and Rodriguez Echavarria, Karina
Digitally fabricated artefacts or 3D replicas have the potential to enrich the interpretation of cultural assets by enhancing visitors' engagement with collections. However, it is still not well understood how replicas work as interpretative means and what are the actual visitors' attitudes towards them. The contribution of this paper is the development and evaluation of a 3D replica within a realistic interpretative scenario. This research deploys a case study focusing on a 3D printed pot representing an ''authentic'' reproduction of a pot made by Pablo Picasso, currently exhibited at the Brighton Museum and Art Gallery. By detailing the research processes and evaluation results, CH professionals can better perceive the dynamics of replicas as interpretative means within realistic situations; understand their positive contributions and weaknesses; and deploy methods and investigation themes, as presented in this paper. In this way, cultural heritage institutions and especially museums can be assisted when introducing replicas to support their audiences. The developments presented in this paper are part of a larger research project which proposes experience designs or experiential frameworks for the provision of 3D replicas to audiences. Our findings highlight that while there is enormous potential, there is also a need to re-educate people on how to engage with cultural heritage through new interpretative frameworks that are less rigid than those traditionally used in museums.
Exploring Expert and Non-Expert Perception of 3D Digital Models of Museum Objects
(The Eurographics Association, 2023) Zumkley, Kira; Echavarria, Karina Rodriguez; Weyrich, Tim; Bucciero, Alberto; Fanini, Bruno; Graf, Holger; Pescarin, Sofia; Rizvic, Selma
Increasingly, museum objects are documented as 3D digital models (3dDM) for scientific study, online exhibition, or personal enjoyment; however, 3dDMs invariably exhibit imperfections due to technological limitations and/or the lack of standardisation in museum object digitisation. Little is known how such inaccuracies are perceived and interpreted by users. Through qualitative interviews and deductive thematic analysis this user study first investigates which inaccuracies in 3dDMs lead to misinterpretations by users and then considers six factors based on the concept of Epistemic Vigilance (EV) and to what extend these factors play a role in the users' ability to correctly understand the information presented within 3dDMs. Only one of eight explored inaccuracies was correctly identified by all participants and background knowledge of the museum object and 3D imaging technology (3DIT) had the most influence on correct interpretation of inaccuracies. Furthermore, trust in the museum publishing the 3dDM and in 3DIT also played a role in how the inaccuracies were perceived. Publishing data about the issues present alongside the 3dDM will increase transparency and further work should therefore concentrate on mechanisms that promote correct interpretation of 3dDMs' limitations to enable museum practitioners to make the most of their digitisation efforts.
An Image-based Approach for Detecting Faces Carved in Heritage Monuments
(The Eurographics Association, 2018) Lai, Yu-Kun; Echavarria, Karina Rodriguez; Song, Ran; Rosin, Paul L.; Sablatnig, Robert and Wimmer, Michael
Heritage monuments such as columns, memorials and buildings are typically carved with a variety of visual features, including figural content, illustrating scenes from battles or historical narratives. Understanding such visual features is of interest to heritage professionals as it can facilitate the study of such monuments and their conservation. However, this visual analysis can be challenging due to the large-scale size, the amount of carvings and difficulty of access to monuments across the world. This paper makes a contribution towards this goal by presenting work-in-progress for developing image-based approaches for detecting visual features in 3D models, in particular of human faces. The motivation for focusing on faces is the prominence of human figures throughout monuments in the world. The methods are tested on a 3D model of a section of the Trajan Column cast at the Victoria and Albert (V&A) Museum in London, UK. The initial results suggest that methods based on machine learning can provide useful tools for heritage professionals to deal with the large-scale challenges presented by such large monuments.
Interactive 3D Artefact Puzzles to Support Engagement Beyond the Museum Environment
(The Eurographics Association, 2021) Rodriguez Echavarria, Karina; Samaroudi, Myrsini; LLoyd, Jack; Weyrich, Tim; Hulusic, Vedad and Chalmers, Alan
The need for online 3D interactive experiences was evidenced during the COVID-19 lockdowns, as audiences across the world have been unable to visit museums, physically interact with their collections on site or digitally interact with technologies and digital media situated within such settings. As a response, this research addresses gaps identified in a review of the digital offerings from UK and US museums during the 2020 lockdowns, highlighting the limited number and nature of 3D interactive offerings provided, despite the wide efforts on 3D digitisation over the last decade. Thus, the research investigates the development and testing of an online 3D interactive activity, resembling a physical activity situated in the archaeological gallery of Brighton Museum and Art Gallery (UK). Through a pilot user survey, the research aims to understand what is the impact of such online offerings to better contextualise heritage collections; enhance cultural heritage learning and appreciation; and complement physical activities of similar nature. The analysis of audiences’' opinions about these interactions can be of great importance, as such activities have the power to enable active access to cultural heritage resources regardless of the physical location of users and transform heritage experiences in the long term. Our research indicates that, while the physical experience might offer advantages as far as it concerns the familiarity with the tactile nature of interaction, the digital counterpart has potential to allow for the experience of assembling the puzzle to achieve a wider reach.
Participatory Co-creation of a Public Sculpture Incorporating 3D Digital Technologies
(The Eurographics Association, 2018) Echavarria, Karina Rodriguez; Janzon, Karin; Wright, Jonathan; Sablatnig, Robert and Wimmer, Michael
This paper presents a interdisciplinary project between artists, civic groups, heritage organisations, technical experts and communities to co-create a piece of artwork for the community. Constellation is the name of the sculpture, and Jonathan Wright, its creator, used a co-creation approach to develop both the design and fabrication of the artwork. To be installed in the Hove Plinth in Brighton & Hove (UK) and commissioned by the Hove Civic Society, this sculpture was envisaged as a celebration of the community's heritage. As such, the mechanical model was designed as a solar system and instead of planets, the most iconic heritage objects in the city were selected to orbit the system. In collaboration with communities, the artist selected these icons which were later 3D scanned in collaboration with technical experts and local heritage organisations. The icons were then manufactured using digital fabrication technologies, and installed in the sculpture. The inauguration of Constellation took place in April 2018 with very good reception from the public. Hence, this paper illustrates the advantages of co-creative approaches which incorporate digital technologies into their workflow.
Preserving Ceramic Industrial Heritage Through Digital Technologies
(The Eurographics Association, 2019) Echavarria, Karina Rodriguez; Weyrich, Tim; Brownsword, Neil; Rizvic, Selma and Rodriguez Echavarria, Karina
World-renowned for its perfection of Bone China and underglaze blue printing techniques, the historic Spode Works in Stokeon- Trent was one of the few ceramic factories in Britain to have operated continuously on its original site until the company ceased trading in 2008. Since then the site has undergone many transitions with much of its former production infrastructure being discarded. Currently the site holds an estimated 70,000 moulds once used in ceramic production dating from the mid 19th century to 2008, which remain as critical elements of British industrial history at risk of disappearing. This paper presents on-going research which explores the application of 3D technologies to create digital surrogates to support the preservation of these Cultural Heritage artefacts, and ways through which their form and context can be explored to creatively disseminate the associated histories of their production. Given the complex nature of ceramic manufacturing as well as the large-scale of the problem, this is not an easy challenge. Hence, the research investigates workflows and technologies which can support creating a digital, and potentially physical, archive with a selection of mould typologies, shapes and complexities. To further understand the complexities of industrial craft practices, the resultant dataset also aims to elucidate material and craft knowledge embodied within such objects. For this, the research looks into novel manufacturing processes, such as 3D printing, to re-invent the physical shapes documented in these moulds in new interpretations of this historic legacy.
Virtual Reality (VR) Interactions With Multiple Interpretations of Archaeological Artefacts
(The Eurographics Association, 2018) Gaugne, Ronan; Samaroudi, Myrsini; Nicolas, Théophane; Barreau, Jean-Baptiste; Garnier, Laurent; Echavarria, Karina Rodriguez; Gouranton, Valérie; Sablatnig, Robert and Wimmer, Michael
Increasingly, the incorporation of 3D printed artefacts into Virtual Reality (VR) and Augmented Reality (AR) experiences is of interest to Cultural Heritage professionals. This is because virtual environments, by themselves, cannot convey information such as the physical properties of artefacts within the environments. This paper presents a methodology for the development of VR experiences which incorporate 3D replicas of artefacts as user interfaces. The methodology is applied on the development of an experience to present various interpretations of an urn which was found at the edge of a cliff on the south east coastal area of the United Kingdom in 1910. In order to support the understanding of the multiple interpretations of this artefact, the system deploys a virtual environment and a physical replica to allow users to interact with the artefacts and the environment. Feedback from heritage users suggests VR technologies along with digitally fabricated replicas can meaningfully engage audiences with multiple interpretations of cultural heritage artefacts.
