Digital Narrative

The technology supporting Interactive Digital Narrative (IDN) is of particular significance to cultural heritage research. IDN technology provides a means of engagement in cultural heritage sites, a medium for culturally significant stories, and culturally significant story-centric games. While previous work in this space has numerous examples of user experience (UX) evaluations of the interactive narrative works themselves, there is significantly less in terms of evaluation of technology for authoring IDN, creating a UX research space in this area that is focused on the audience and not authors. We propose to balance this focus by considering the UX of authoring tools more closely. In this work, we undertake a review of the state of the art of authoring tools for IDN, such as story-centric games, and report on a rigorous UX evaluation of representative technologies (n = 21). We also address the challenges of UX research for these tools through an original evaluation methodology where authors complete a story composed of representative story features. Our study leads us to conclude seven UX principles for IDN authoring tools that explore both how authors use tools to create story-focused games and how the interface for these tools impacts the creative process.

Purpose This paper aims to evaluate four different simultaneous localization and mapping (SLAM) systems in the context of localization of multi-legged walking robots equipped with compact RGB-D sensors. This paper identifies problems related to in-motion data acquisition in a legged robot and evaluates the particular building blocks and concepts applied in contemporary SLAM systems against these problems. The SLAM systems are evaluated on two independent experimental set-ups, applying a well-established methodology and performance metrics. Design/methodology/approach Four feature-based SLAM architectures are evaluated with respect to their suitability for localization of multi-legged walking robots. The evaluation methodology is based on the computation of the absolute trajectory error (ATE) and relative pose error (RPE), which are performance metrics well-established in the robotics community. Four sequences of RGB-D frames acquired in two independent experiments using two different six-legged walking robots are used in the evaluation process. Findings The experiments revealed that the predominant problem characteristics of the legged robots as platforms for SLAM are the abrupt and unpredictable sensor motions, as well as oscillations and vibrations, which corrupt the images captured in-motion. The tested adaptive gait allowed the evaluated SLAM systems to reconstruct proper trajectories. The bundle adjustment-based SLAM systems produced best results, thanks to the use of a map, which enables to establish a large number of constraints for the estimated trajectory. Research limitations/implications The evaluation was performed using indoor mockups of terrain. Experiments in more natural and challenging environments are envisioned as part of future research. Practical implications The lack of accurate self-localization methods is considered as one of the most important limitations of walking robots. Thus, the evaluation of the state-of-the-art SLAM methods on legged platforms may be useful for all researchers working on walking robots’ autonomy and their use in various applications, such as search, security, agriculture and mining. Originality/value The main contribution lies in the integration of the state-of-the-art SLAM methods on walking robots and their thorough experimental evaluation using a well-established methodology. Moreover, a SLAM system designed especially for RGB-D sensors and real-world applications is presented in details.

The practice of digitizing cultural heritage sites is gaining ground among conservation scientists and scholars in architecture, art history, computer science, and related fields. Recently, the location of such sites in areas of intense conflict has highlighted the urgent need for documenting cultural heritage for the purposes of preservation and posterity. The complex histories of such sites requires more than just their digitization, and should also include the meaningful interpretation of buildings and their surroundings with respect to context and intangible values. Project Anqa is an interdisciplinary and multi-partner effort that goes beyond simple digitization to record at-risk heritage sites throughout the Middle East and Saharan Africa, most notably in Syria and Iraq, before they are altered or destroyed. Through a collaborative process, Anqa assembles documentation, historically contextualizes it, and makes data accessible and useful for scholars, peers, and the wider public through state-of-the-art tools. The aim of the project is to engage in capacity-building on the ground in Syria and Iraq, as well as to create an educational web platform that informs viewers about cultural heritage in the region through research, digital storytelling, and the experience of virtual environments.

A key challenge to move forward the state of the art in games-based learning systems is to facilitate instructional content creation by the domain experts. Several decades of research on computer aided instruction have demonstrated that the expert has to be deeply involved in the content creation process, and that is why so much effort has been devoted to building authoring tools of all kinds. However, using videogame technology to support computer aided instruction poses some new challenges on expertfriendly authoring tools, related to technical and cost issues. In this chapter the authors present the state of the art in content creation for games-based learning systems, identifying the main challenges to make this technology cost-effective from the content creation point of view.

The approval by the Ukrainian government of the concept for the introduction of BIM technologies in the construction of Ukraine provides many opportunities for the development and implementation of BIM as a tool for creating archival documentation and storing the state register of cultural heritage sites of Ukraine, in particular architectural monuments. The application of the principles of BIM technologies to historical buildings is widespread in the EU countries and allows combining 3D-models with textual information (databases) and is included in international practice as HBIM (BIM technologies applicable to the sites of historical heritage). The proposed method of modeling and description using software tools, applying the best excellent achievements, allows improving the state of registration of historical sites, architectural monuments and urban planning on the territory of Ukraine.

The obligation to preserve underwater cultural heritage is a core principle of the UNESCO Convention on the Protection of the Underwater Cultural Heritage. A key element of this obligation is a balance of scientific research, protection, and the promotion of responsible access to underwater cultural heritage sites. Such a balance requires the setting up of a network of communication between the tourism and heritage sectors on the one hand and the maritime and diving communities on the other hand. A variety of approaches have been developed to promote responsible access to underwater cultural heritage sites, and since the vast majority of the public does not dive, this also includes the development of virtual access. In Malta, maritime archaeology can be traced to humble and sporadic beginnings in the 1950s. The following decades brought a growing interest in diving activities and a rising number of diving schools and clubs. Whilst Malta has today established itself as a diving tourism destination, responsible access to underwater cultural heritage sites was not always entrenched in dive operations or institutionally recognized. The protection and management of underwater cultural heritage has recently been firmly established within Heritage Malta, the national agency for museums, conservations, and cultural heritage. This paper is intended to outline the trajectory of Malta’s underwater cultural heritage management and to present the innovative and state of the art public access system that is managed by the Underwater Cultural Heritage Unit within Heritage Malta.

Abstract:Immovable cultural heritage is still at risk of being neglected by the state responsible for heritage sites, by urban planning of big cities, and by armed conflicts around the world. Normally, because it is immovable, the international community cannot do very much. It can ban the trade of items that became movable property when detached from buildings or illegally excavated in certain protected sites. In other cases, it is the responsibility of the national state to care for cultural heritage and cultural objects. International conventions may furnish help and advice and provide for monitoring any risk to the cultural heritage of state parties.
