The implementation of usability in mobile augmented reality (MAR) learning applications has been utilized in a myriad of standards, methodologies, and techniques. The usage and combination of techniques within research approaches are important in determining the quality of usability data collection. The purpose of this study is to identify, study, and analyze existing usability metrics, methods, techniques, and areas in MAR learning. This study adapts systematic literature review techniques by utilizing research questions and Boolean search strings to identify prospective studies from six established databases that are related to the research context area. Seventy-two articles, consisting of 45 journals, 25 conference proceedings, and two book chapters, were selected through a systematic process. All articles underwent a rigorous selection protocol to ensure content quality according to formulated research questions. Post-synthesis and analysis, the output of this article discusses significant factors in usability-based MAR learning applications. This paper presents five identified gaps in the domain of study, modes of contributions, issues within usability metrics, technique approaches, and hybrid technique combinations. This paper concludes five recommendations based on identified gaps concealing potential of usability-based MAR learning research domains, varieties of unexplored research types, validation of emerging usability metrics, potential of performance metrics, and untapped correlational areas to be discovered.

Nowadays, the network traffic has increased exponentially due to amount of information and number of users which are connected to Heterogeneous Networks (HetNets) in this case we focus on LTE-WiFi technologies. This is an important issue that need to solve for an efficient network communication process end to end. The aim of this article is to present the-state-of-theart about performance models for LTE-WiFi HetNets and a classification of key performance metrics which help to analyze HetNets behaviour. The article concludes with a methodology that will be applied later for this research problem, as well as opened research questions. We believe, that apply our methodology using accurate and suitable models in HetNets the transmission process will have a fairness traffic when both networks coexist.

Abstract Research students usually encounter great difficulties in setting up a viable research project mainly because, on the one hand they lack familiarity with the philosophical underpinnings of major paradigms used in educational research: quantitative, qualitative or mixed, and on the other hand , they do not associate the corresponding research types with these paradigms : experimental, non experimental for the former, and interactive or non interactive for the second and the for the latter whether it is explanatory or exploratory, in addition to the importance of triangulation in any research study . These paradigms determine not only the formulation of the problem chosen for research and the associated research questions or hypothesis but also and more importantly, the sampling procedure as well as the selection of the appropriate research tools and the way the collected data is analysed and discussed. This survey of the major paradigms in educational research and their implications for the design of any research study will hopefully provide them with the necessary guidance to approach their research project with more confidence et more efficiency.

New media has expanded our experiences of art forms from the retinal to the immersive and embodied. This evolution offers novel experiences as we push the boundaries of these emerging technologies. Recently, I have been working with augmented reality headsets. These headsets sometimes separate us from the physical and the sensory, substituting the world of matter for the virtual. My research questions whether the exchange of the sensory for the digital provides an opportunity to redesign experiences that act upon the body? Developing sound design to create the illusion of touching, could our skin become a site where artworks are experienced?

Translational research applies scientific techniques to achieve practical outcomes, connecting pure research and pure practice. Many translational research types have arisen since the mid-1900s, reflecting the need to better integrate scientific advancement with policy and practice. Water, sanitation, and hygiene (WaSH) development efforts have aimed to reduce morbidity and mortality and improve service delivery; thus, associated research has a strong orientation toward applied studies that use diverse methods to support decision-making. Drawing from knowledge that emerged to support other professional fields, such as manufacturing and clinical healthcare, we characterize different types of translational research and clarify nomenclature and principles. We describe study approaches relevant to translational research questions, and offer overarching recommendations, specific examples, and resources for further study as practical advice to professionals who seek to apply translational methods to WaSH problems. To enhance collective outcomes, professionals should mindfully align projects within the translational spectrum. We further recommend overarching good practices such as documenting intervention adaptations, overtly considering contextual factors, and better distinguishing efficacy from effectiveness research by replicating studies in different contexts. By consciously improving the compatibility and linkages between WaSH science and practice, this guide can accelerate urgently needed progress toward global development goals.

Purpose This paper aims to selects 59 journals that focus on data science research in 14 disciplines from the Ulrichsweb online repository. This paper analyzes the aim and scope statement using both quantitative and qualitative methods to identify the research types and the scope of research promoted by these journals. Design/methodology/approach Multiple disciplines are involved in data science research and publishing, but there lacks an overview of what those disciplines are and how they relate to data science. In this study, this paper aims to understand the disciplinary characteristics of data science research. Two research questions are answered: What is the population of journals that focus on data science? What disciplinary landscape of data science is revealed in the aim and scope statements of these journals? Findings Theoretical research is mainly included in journals that belong to statistics, engineering and sciences. Almost all data science journals include applied research papers. Keywords analysis shows that data science research in computers, statistics, engineering and sciences appear to share characteristics. While in other disciplines such as biology, business and education, the keywords are indicative of the types of data to be used and the special problems in these disciplines. Originality/value This is the first study to use journals as the unit of analysis to identify the disciplines involved in data science research. The results provide an overview of how researchers and educators from different disciplinary backgrounds understand data science research.

This paper presents a Systematic Literature Review (RSL) on the use of Gamification and Augmented Reality applied in Education. RSL enabled mapping and knowledge of the current state of related studies. Thirty articles related to the state of the art were analyzed. From the analysis, it was found that there is no specific learning assessment methodology when applying the Augmented Reality and Gamification tools. An analysis of the results was made to answer the research questions. The study showed that lack of programming knowledge is also a factor that hinders the advancement of research since the researcher must know how to develop the application or have in his team someone who has the competence to do so. Finally, we present the comparatives and analyzes of the studies to obtain answers based on the research questions developed.

New technologies such as Augmented Reality (AR) have already been exploited in the promotion of unique and well-known cultural assets. Nevertheless, different types of heritage assets can be found scattered in many different places, in both urban and rural landscapes, where AR applications may not function properly due to problems concerning the effectiveness of GPS or image recognition methods. It is an important issue that limits the exploitation of AR technology with a view to hidden cultural heritage promotion. The current study presents a hybrid image recognition technique used in an AR application and its evaluation in the outdoor settings. The hybrid technique is based on an image-based marker and its evaluation mainly aimed to study if and to what extent it is accepted by the users, if it raises aesthetic issues, and if it affects the use and acceptance of the AR in culture field. The evaluation was based on a qualitative research and the results showed that to most participants the used hybrid technique does not create an aesthetical issue. Additionally, all participants found the AR app useful and easy to use and they consider that the AR technology can significantly contribute to the promotion of cultural heritage.

In this paper, we present a new Augmented Reality (AR) tracking technique that integrates the marker-based tracking with the tracking ability of a commercial mobile robot. The role of the mobile robot is to co-work with the user for extending the working space of the marker-based tracking technique. The robot follows the user’s movements during the exploration in the AR environment and updates the position of a fiducial marker, which is fixed on it. The robot is automatically controlled through the device used to visualize the AR scene. The paper discusses the issues related to the integration of these two tracking techniques and proposes an AR application, which has been developed to demonstrate the feasibility of our approach. Technical issues and performances have been assessed through several testing sessions.
