This study scrutinizes the existing literature regarding use of augmented reality and gamification in education to establish its theoretical basis. A systematic review following Preferred Reporting Items for Systematic Reviews Meta-Analyses (PRISMA) statement was conducted. To provide complete valid information, all types related studies educational stages subjects throughout years were investigated. In total, 670 articles from 5 databases (Scopus, Web Science, Google Scholar, IEEE, ERIC)...
This study aims to understand the public’s perspectives, sentiments, attitudes, and discourses regarding adoption, integration, use of augmented reality virtual in education general by analyzing social media data. Due its nature, Twitter was selected platform. Over 17 million tweets were retrieved from January 2010 December 2020 four datasets created. Two them referred these technologies two their educational use. The data analyzed using text mining, sentiment analysis (e.g., polarity...
This study aims to evaluate the impact of using augmented reality, gamification, and serious games in computer science education. The presents development process an educational mobile application, describes experiment that was conducted involved 117 higher education students, analyzes results a 49-item paper-based questionnaire. In total, 8 research questions were explored. revealed several benefits can be yielded when integrating such applications teaching learning activities actively...
Augmented Reality (AR) could provide key benefits in education and create a richer user experience by increasing the motivation engagement of students. To this end, current paper presents system with three AR applications for teaching physics fifth sixth grades primary school first grade secondary school, ultimate goal is development unified platform that covers subject all classes K-12 education. The provides useful tool to familiarize both teachers pupils technologies, aiming improve...
The augmented reality game-based learning (ARGBL) approach is an advantageous pathway for the development and enhancement of teaching processes. To this end, paper presents design ARGBL application implementation physics experiments in fifth grade a Greek primary school. purpose system twofold: to educate entertain. For reason, treasure hunt game was implemented, which allows students interact with digital world manipulate virtual objects use (AR) device. Then, according instructions, have...
Augmented Reality is an emerging educational technology that has the potential to provide innovative methods of teaching and create engaging learning experiences. applications implementing game-based design could enrich education by increasing motivation engagement enabling better outcomes. Similarly, Reality, in context Geography, enhance process user experience through visualization content a understanding abstract concepts. Therefore, this study, (a) three specially designed are described...
Active learning, a student-centered approach, engages students in the learning process and requires them to solve problems using educational activities that enhance their outcomes. Augmented Reality (AR) has revolutionized field of education by creating an intuitive environment where real virtual objects interact, thereby facilitating understanding complex concepts. Consequently, this research proposes application, called “Cooking Math”, utilizes AR promote active sixth-grade elementary...
Rapid development of mobile computing devices has evolved technologies that are always and everywhere available. Augmented Reality is such a technology enriches the real-world environment with audio, video useful information. The agricultural sector an area where can be applied tremendous benefits. In this paper, we present FarmAR, prototype application exploits in order to identity plant provide information farmer regarding through device. Moreover, based on knowledge base which consists...
With a view to creating mixed reality that combines coexisting real and virtual objects providing users with real-time access information in an interactive manner, augmented enriches users’ physical environment by incorporating digital rendering them the proper time spatial framework. Due its nature, can be combined exploit other innovative technologies order improve efficiency potentials. Some such are semantic web, knowledge graphs deep learning. The study main purpose contribution is...
It is essential to consider the public’s viewpoints when it comes significant issues, such as adoption and integration of technologies in education. This study aims at analyzing comprehending perspectives, sentiments attitudes towards use virtual reality general educational settings. After setting necessary data requirements, 10,457,344 related tweets from Twitter were identified retrieved. The was then analyzed using text mining sentiment analysis. Based on results, public positively...
In this paper, we present GOQL (Graphical Object Query Language). provides a user-friendly graphical interface to support ad-hoc queries for object-oriented database applications. Such are translated into standard OQL queries. illustrate the use and expressiveness of using an example, briefly survey similar work developments in market literature.
We provide a brief formal definition of the Users View (UV) Graphical Object Query Language (GOQL). The UV provides graphical representation for object-oriented database schemas and hides from end-users most perplexing details model, such as methods, hierarchies relationships. In particular, does not distinguish between attributes relationships, encapsulates is-a hierarchy utilises number desktop metaphors to present schema that is easy be understood by end-users. Thus, environment, through...
The paper addresses issues related to the design of a graphical query mechanism that can act as an interface any object-oriented database system (OODBS), in general, and object model ODMG 2.0, particular. In brief literature survey work is given, analysis methodology allows evaluation such languages proposed. Moreover, user's view level new language, namely GOQL (Graphical Object Query Language), for 2.0 presented. provides schema does not contain perplexing details schema, it also...
The authors present a graphical query language, GOQL (Graphical Object Query Language), for object-oriented data base systems, in general, and the object model of ODMG 2.0, particular. A detailed literature survey related work is given, an analysis methodology that allows evaluation such languages proposed. Moreover, user's view presented. provides schema does not contain any perplexing details database schema; it also interface supports ad hoc queries applications. Because there direct...
The touch screen devices allow us to construct user friendly graphical interfaces using the gesture technology which is very popular for novice users. In this paper, we present a new query language relational databases designed support design philosophy and full functionality of SQL addressed non-expert users on databases. EGQL (Easy Gesture Query Language) implemented Android platform compact multi-touch screens. Moreover, Metaphors, Color other like zoom are used best comprehension...
The study presented in this paper is a controlled experiment, aiming at investigating the understandability and correctness two query languages, namely KINISIS against XQuery. XQuery W3C standard language for XML documents. graphical which designed implemented upon XQuery, using metaphors extracted from European Road Traffic Act. We conducted experiment order to assess users’ performance, with respect understanding correctness, developing queries findings, collected statistically analysed...
