Abstract
Geotechnologies have a long tradition in several areas of society and research. The recent development of the ‘Internet of Everything’ (IoE) and Geographic Information Systems (GIS) technologies opened several doors to the contribution of tourism. Emergent technologies contributions to tourism and planning such as web mapping, augmented reality (AR), crowdsourcing and crowdsensing are relatively recent, and there is a lack of research around their potential for Creative Tourism enhancement. For example, combining web mapping with AR or storytelling can be an excellent contribution to operators, planners and tourists. For research purposes, new opportunities are open, particularly by integrating community-shared data. It is well known for the popularity of social networks, the exponential growth of photo sharing, but few studies have been implemented to understand their contribution to research. This chapter focuses on emerging geotechnologies concerning cultural mapping, Creative Tourism and sustainability. Since it is a new growing niche, more research is needed to develop and understand the potential of new approaches. Besides traditional techniques such as quantitative (e.g. surveys) and qualitative ones (e.g. interviews, focus groups and world café), it revises the role of geotechnologies on Creative Tourism development and growing activities. Results from case studies from Europe are analysed.

Abstract
Purpose
A simultaneous solution to the localization and mapping problem of a graph‐like environment by a swarm of robots requires solutions to task coordination and map merging. The purpose of this paper is to examine the performance of two different map‐merging strategies.
Design/methodology/approach
Building a representation of the environment is a key problem in robotics where the problem is known as simultaneous localization and mapping (SLAM). When large groups of robots operate within the environment, the SLAM problem becomes complicated by issues related to coordination of the elements of the swarm and integration of the environmental representations obtained by individual swarm elements. This paper considers these issues within the formalism of a group of simulated robots operating within a graph‐like environment. Starting at a common node, the swarm partitions the unknown edges of the known graph and explores the graph for a pre‐arranged period. The swarm elements then meet at a particular time and location to integrate their partial world models. This process is repeated until the entire world has been mapped. A correctness proof of the algorithm is presented, and different coordination strategies are compared via simulation.
Findings
The paper demonstrates that a swarm of identical robots, each equipped with its own marker, and capable of simple sensing and action abilities, can explore and map an unknown graph‐like environment. Moreover, experimental results show that exploration with multiple robots can provide an improvement in exploration effort over a single robot and that this improvement does not scale linearly with the size of the swarm.
Research limitations/implications
The paper represents efforts toward exploration and mapping in a graph‐like world with robot swarms. The paper suggests several extensions and variations including the development of adaptive partitioning and rendezvous schedule strategies to further improve both overall swarm efficiency and individual robot utilization during exploration.
Originality/value
The novelty associated with this paper is the formal extension of the single robot graph‐like exploration of Dudek et al. to robot swarms. The paper here examines fundamental limits to multiple robot SLAM and does this within a topological framework. Results obtained within this topological formalism can be readily transferred to the more traditional metric representation.

Abstract
Purpose
Although acknowledged as a principal dimension in the context of text mining, time has yet to be formally incorporated into the process of visually representing the relationships between keywords in a knowledge domain. This paper aims to develop and validate the feasibility of adding temporal knowledge to a concept map via pair-wise temporal analysis (PTA).
Design/methodology/approach
The paper presents a temporal trend detection algorithm – vector space model – designed to use objective quantitative pair-wise temporal operators to automatically detect co-occurring hot concepts. This PTA approach is demonstrated and validated without loss of generality for a spectrum of information technologies.
Findings
The rigorous validation study shows that the resulting temporal assessments are highly correlated with subjective assessments of experts (n = 136), exhibiting substantial reliability-of-agreement measures and average predictive validity above 85 per cent.
Practical implications
Using massive amounts of textual documents available on the Web to first generate a concept map and then add temporal knowledge, the contribution of this work is emphasized and magnified against the current growing attention to big data analytics.
Originality/value
This paper proposes a novel knowledge discovery method to improve a text-based concept map (i.e. semantic graph) via detection and representation of temporal relationships. The originality and value of the proposed method is highlighted in comparison to other knowledge discovery methods.

Abstract
Purpose
Tangible physical maps which are enhanced by new digital forms of interaction can become an invaluable asset for learning geography in an embodied way. The purpose of this work is to evaluate an interactive augmented three-dimensional (3D) tangible map on which students interact and travel with their fingers.
Design/methodology/approach
A total of 58 fourth-grade students from eight elementary schools participated in the study. The participants played with the FingerTrips environment in 24 sessions and in groups of two or three. Each session lasted for about 20-25 min. After completing the interactive game, the students answered a questionnaire concerning their attitudes toward the tangible environment and participated in a short interview.
Findings
Students’ responses revealed that FingerTrips managed to transform the experience of meeting new places, understanding spatial relations and learning geography. Students supported that such an approach is closer to their interactive experiences and expectations, and exploits embodied learning affordances to achieve enjoyable learning. Students identified their finger-based trips as an effective and intriguing static haptic guidance that helped them learn more effectively.
Originality/value
The specific approach has two distinctive characteristics. First, a new interaction style on the map is suggested, the use of trips with fingers. Students have to follow predefined engraved paths on the 3D terrain to sense distances and changes in altitude and “touch” the topology asked to understand and explore. Second, it is examined whether a low fidelity interactive 3D terrain, which can be easily reconstructed and reprogrammed by primary school students, can become a useful canvas for learning geography.

Abstract
Purpose
This paper aims to bring in augmented reality (AR) into navigation systems to rectify the issues mentioned. This paper proposes an AR enhanced navigation system for location automated teller machine (ATM) counters (AR-ATM) and branches of banks based on user’s choice. Upon selecting the ATM, the navigational path to the destination is drawn from the current location, thereby the user can reach the ATM through the optimal path.
Design/methodology/approach
Traditional navigation systems require users to map with the real world environment as and when required and also may lead to incorrect path due to minor difference in distance. The traditional navigation systems’ also does not take into consideration the ergonomics and safety of the user.
Findings
In this system, a camera lens is used, which is directed down the street at eye level and the application displays the location of ATMs and bank branches and also provides information about the locations like distance and time through the AR superimposed object.
Originality/value
The application also provides indoor navigation, especially in a multi-storeyed building. Experiments are performed on smartphones that support AR, and the results are promising with no lag in time frame of the real object and virtual object. To determine the factors that regulate the suggested AR tracking mechanism, a quantitative evaluation of the experimental data is also performed. The testing of implemented AR-ATM from the standpoint of end-users is undertaken to evaluate real-time usage comfortability, and the results have been determined to be extremely satisfactory.

Abstract
Purpose
The purpose of this paper is to present a new effective integration method for cyclic plasticity models.
Design/methodology/approach
By defining an integrating factor and an augmented stress vector, the system of differential equations of the constitutive model is converted into a nonlinear dynamical system, which could be solved by an exponential map algorithm.
Findings
The numerical tests show the robustness and high efficiency of the proposed integration scheme.
Research limitations/implications
The von‐Mises yield criterion in the regime of small deformation is assumed. In addition, the model obeys a general nonlinear kinematic hardening and an exponential isotropic hardening.
Practical implications
Integrating the constitutive equations in order to update the material state is one of the most important steps in a nonlinear finite element analysis. The accuracy of the integration method could directly influence the result of the elastoplastic analyses.
Originality/value
The paper deals with integrating the constitutive equations in a nonlinear finite element analysis. This subject could be interesting for the academy as well as industry. The proposed exponential‐based integration method is more efficient than the classical strategies.

Abstract
Education and new technologies travel parallel pathways, with each often informing development of the other. In recent decades, educators have utilized technologies, such as television and the Internet, to develop and deliver course content. More recently, another technology has emerged that might possibly change education as it is currently practiced. Augmented reality merges manipulable digital imagery into real-world spaces and in real time. The technologies used to create augmented environments already exist in the mass market and have already begun to show up in a wide variety of fields, including education. This chapter will provide an overview of augmented reality and explore current and potential uses in higher education.

Abstract
Purpose
Over the past few years, advertisers have adopted augmented reality (AR) technology in advertising campaigns. To overcome the geographic limit, advertisers record the interaction between people and virtual objects in AR campaigns and upload promotional videos on social media, such as YouTube. This study aims to develop and validate a measurement instrument to gauge the content characteristics of YouTube videos featuring AR ad campaigns.
Design/methodology/approach
To this end, possible items were generated via a review of prior literature, and supplemented by content analysis and a free association task. The measurement instrument was then refined and validated using a pretest of a general consumer sample, and further validated using a second general consumer sample with two online experiments.
Findings
Results indicate that the content characteristics of YouTube AR campaigns can be measured using a 15-item, four-construct (informativeness, novelty, entertainment and complexity) instrument. This study also found the direct and indirect relationships between each content characteristic and ad efficacy variables.
Practical implications
The measurement instrument provides practitioners with a broad measure of the content characteristics of YouTube AR campaigns. The results also reveal the effect of different content features of YouTube AR campaigns on the outcome of successful advertising execution.
Originality/value
This study contributes to the body of knowledge in marketing communications via exploring the primary content characteristics of AR advertising campaign videos uploaded on YouTube. It also develops an understanding of the impact of AR technology on consumer behavior and on the experience that it delivers.

Abstract
Purpose
In recent years, augmented reality (AR) has shown its potential to assist various construction activities. Its use commonly requires additional refinement to be integrated into the building information modeling (BIM) process. Nevertheless, few studies have investigated AR implementation in BIM-enabled projects because of numerous challenges related to its implementation. This study aims to investigate the implementation of AR in construction and identify the critical mechanisms for implementing BIM-AR successfully.
Design/methodology/approach
A mixed methodology was adopted for this study. First, this work presents a bibliometric analysis covering articles obtained from Scopus database published between 2000 and 2022. A sample size of 65 research papers pertinent to AR in construction was analyzed using VOSviewer software. Second, a participatory case study was conducted for a BIM-enabled project in China to gain insight into how BIM-AR implementation in construction is achieved.
Findings
The findings from the bibliometric analysis show an increasing interest in AR research within construction. The results indicate that AR research focuses on four clusters: real-time communication, project management, construction activities and education. Findings from the case study provide an empirical experience of AR application scenarios in a BIM-enabled project. Concomitantly, 15 critical success factors that influence BIM-AR implementation were finally identified and demonstrated.
Originality/value
This study provides a rich insight into the understanding and awareness of implementing AR. First, the findings are beneficial to construction practitioners and researchers because they provide a concentrated perspective of AR for emerging activities in the construction industry. Second, the results obtained from the case study could provide a useful guide for effectively implementing AR in a BIM-enabled construction project. Overall, this study may stimulate further research on AR-related studies in construction, such as BIM integration, factor analysis and construction education.
