Design of a location-based augmented reality game for the development of key 21st century competences in primary education

The use of augmented reality games (ARGs) in education has gained increased attention from curriculum developers, teachers, and researchers in the past decade. Research findings show that ARGs can promote meaningful learning environments that foster key competences for the 21st century. This paper presents the design process of “EcoAegean”, an ARG for mobile devices, which was implemented in primary classroom environments to support the development of students’ key competences in the context of sustainability. The game was created using an open augmented reality software platform and its design was based on contemporary theoretical underpinnings regarding the use of such games in educational contexts. In the first section of the paper, we describe the design procedures of the learning scenario as well as the game itself. In the last section of the paper, we offer a set of critical insights on the design and implementation of mobile augmented reality games for the purpose of supporting students’ development of key 21st century competences.</p

Several species were selected for investigation, including orangutans, Komodo dragons, Kakapo (Strigops habroptilus), Javan rhinos, Amur leopards, and vaquitas (Phocoena sinus). Augmented reality, a technology that merges the real and virtual worlds through computer devices, was employed by the author to develop an animal recognition application. The aim was to create an engaging educational tool, particularly targeting school children, to facilitate learning about endangered animals. The research progressed through three stages: gathering information on endangered animals globally, examining existing augmented reality applications, and designing markers for detection using the fast corner detection algorithm. Android, a Linux-based mobile operating system, offered an open platform for developers to create applications compatible with various mobile devices. Consequently, the outcome of this study manifested as an augmented reality-based application that delivers comprehensive information on endangered species. The application's potential to serve as a captivating medium for education and knowledge acquisition is highly anticipated

The Urban CoCreation Lab—An Integrated Platform for Remote and Simultaneous Collaborative Urban Planning and Design through Web-Based Desktop 3D Modeling, Head-Mounted Virtual Reality and Mobile Augmented Reality: Prototyping a Minimum Viable Product and Developing Specifications for a Minimum Marketable Product

Both policy and research highlight the importance of diverse stakeholder input in urban development processes but visualizing future built environments and creating two-way design communication for non-expert stakeholders are challenging. The present study develops an intuitive and simplified 3D modeling platform that integrates web-based desktop, virtual reality and mobile augmented reality technologies for remote simultaneous urban design collaboration. Through iterative prototyping, based on two series of workshops with stakeholders, the study resulted in such an integrated platform as a minimum viable product as well as specifications for a minimum marketable product to be used in real projects. Further study is required to evaluate the minimum level of detail in the 3D modeling necessary for good perception of scale and environmental impact simulation

Design of a Mobile Augmented Reality Platform with Game-Based Learning Purposes

Augmented reality (AR) is an emergent technology that overlays virtual objects into the real environment. Lately, AR is gaining prominence in education because of its increasing affordability through computers or mobile technologies. In addition, research sustaining the benefits of AR to promote student’s engagement to learn is increasing every day. However, the literature identifies lack of studies about the use of AR in education, namely, studies focused on the development of AR games designed over specific learning objectives (game-based learning). This paper presents a mobile augmented reality platform with learning purposes. The platform includes a mobile application that consists of a location-based game targeted to promote learning about the universe. Furthermore, it includes a back-office that allows teachers to introduce information about celestial bodies and also develop a set of multiple-choice questions to assess student’s learning about the subject matters they teach. The mobile application provides the users with physical movement and social interaction in the real world, while playing the game and for this reason it is included in the pervasive games’ paradigm. Besides engaging the students to play the game, we argue that this platform may be used as a resource to be implemented in informal and formal learning environments.Funding: This work is supported by national funds through FCT - Foundation for Science and Technology, I.

Aceh's Historic Tourist Attractions: An Augmented Reality-Based Prototype of a Virtual Tour Application

Indonesia has attractive tourist destinations for tourism such as beautiful interior areas and historical places. The purpose of this research is to design and build a virtual tour application for Aceh tourism objects using augmented reality. One of the problems that occur in tourist objects is that foreign tourists do not have an idea about the tourist objects they want to visit. The technology used in this study and previous research is Augmented Reality, but previous research only displays 3D tourist objects, while in this study, augmented reality technology is incorporated into the design of the 4 Aceh tourist attractions by showing a 3-dimensional illustration of the object as a whole. for the outside of the building and displays a virtual tour image in the form of a video to illustrate the inside of the tourist attraction building on the Android mobile platform. Based on the results of distance and angle testing, the best (ideal) distance that produces clear and bright marker detection is found at a distance between 25 to 45 cm, while the best angle is between an angle with a slope of 0° to 60°. Measurements of distances and angles are carried out using threads, bows and measuring tapes. The 3D object is successfully displayed by pointing the camera at the marker to be detected.

Java ME:n ja WRT:n soveltuvuus GPS-sisältöpalveluun

Opinnäytetyö käsittelee Java ME- ja WRT-ohjelmointiympäristöjen soveltuvuutta paikkatietoon sidonnaisen sisältöpalvelun toteutukseen. Opinnäytetyössä käsitellään opastuspalveluita laajennetun todellisuuden palveluiden näkökulmasta. Työn tavoitteena oli valittuja ohjelmointiympäristöjä vertailemalla löytää teknisiltä ominaisuuksiltaan paremmin palvelumuotoon soveltuva vaihtoehto. Vertailun lähtökohdaksi työssä tutkittiin laajennetun todellisuuden palveluiden määritteitä sekä aiemmin Pohjois-Karjalassa toteutetuissa laajennetun todellisuuden palveluissa esiintyneitä ongelmia. Työn toiminnallinen tavoite oli toteuttaa kaksi matkapuhelinsovellusta valittuja ohjelmointiympäristöjä käyttämällä. Matkapuhelinsovellukset toimivat laajennetun todellisuuden palveluina tarjoten ääni- ja kuvasisältöjä. Sovelluksissa käytettiin paikkatietoa yhdistämään tarjotut sisällöt opastuskohteisiin. Palvelun kohdeympäristönä toimi Lieksassa sijaitseva Vuonislahden kylä. Työssä vertailtiin toteutettuja matkapuhelinsovelluksia sekä tarkasteltiin niiden soveltuvuutta laajennetun todellisuuden palvelualustoiksi. Vertailun tulokset osoittivat, että WRT oli parempi vaihtoehto laajennetun todellisuuden palvelualustaksi. Vaikka Java ME toimi WRT:tä useammassa matkapuhelinmallissa, on WRT käytettävyyden ja suorituskyvyn kannalta parempi vaihtoehto. Työssä käsiteltiin matkapuhelinsovelluksia kirjoittajan omien kokemusten ja taustatiedon pohjalta. Lähdeaineistona työssä käytettiin laajennetun todellisuuden palveluita käsittelevää kirjallisuutta, internetlähteitä sekä aiemmin toteutettuja palveluita. Toiminnallisena lopputuloksena syntyneet sovellukset jäävät pilottitoteutuksina Pohjois-Karjalan ammattikorkeakoulun TG4NP-hankkeen testaus- ja tutkimuskäyttöön.This bachelor’s thesis deals with the suitability of Java ME and WRT-software development environments in implementing location based mobile phone content service. The thesis deals with the guidance services from the perspective of augmented reality services. The goal of this thesis was to find a better software development environment for the service by comparing technical features of selected environments. As a baseline for comparison the thesis used the main features of augmented reality services and examined development needs and problems from previously carried out services in North Karelia. The functional purpose of the thesis was to create two augmented reality mobile phone applications by using selected software development environments. The created applications work as augmented reality mobile phone services and contain audio and visual contents. Mobile applications used the location based services to combine the contents to the real world places. The service was located in Vuonislahti-village in Lieksa, North Karelia. The thesis compared the created mobile applications and examined their suitability as a platform for augmented reality services. The result of the comparison was that WRT software development environment found to be a better option to be used as a platform for augmented reality service. Even though Java ME -environment supports more devices, the WRT was better both in usability and performance. The thesis used the author’s previous experiences and background knowledge of mobile phone applications as a source. Other used sources were professional literature about augmented reality services, internet sources and knowledge from previously carried out services. The applications will remain with NKUAS TG4NP project for testing and research purposes

Technology and Caregiving: Emerging Interventions and Directions for Research.

An array of technology-based interventions has increasingly become available to support family caregivers, primarily focusing on health and well-being, social isolation, financial, and psychological support. More recently the emergence of new technologies such as mobile and cloud, robotics, connected sensors, virtual/augmented/mixed reality, voice, and the evermore ubiquitous tools supported by advanced data analytics, coupled with the integration of multiple technologies through platform solutions, have opened a new era of technology-enabled interventions that can empower and support family caregivers. This paper proposes a conceptual framework for identifying and addressing the challenges that may need to be overcome to effectively apply technology-enabled solutions for family caregivers. The paper identifies a number of challenges that either moderate or mediate the full use of technologies for the benefit of caregivers. The challenges include issues related to equity, inclusion, and access; ethical concerns related to privacy and security; political and regulatory factors affecting interoperability and lack of standards; inclusive/human-centric design and issues; and inherent economic and distribution channel difficulties. The paper concludes with a summary of research questions and issues that form a framework for global research priorities

Website Technology Trends for Augmented Reality Development

Augmented reality (AR) is a technology that is gaining increasing attention from academics and industry. AR is relied upon to be an innovative technology to enrich ways of interacting with the physical and cyberspace around users that can enhance user experience in various fields. Platforms for AR applications are usually hardware based and mobile based, for mobile applications AR is usually based. AR-based hardware requires quite expensive support, this is seen from the rendering space requirements and this makes it inflexible while AR-based applications on mobile smartphones require large storage space and do not make it convenient for cross-platform use. Currently many researchers are trying to create and develop website-based AR, as a solution to the spread of AR to be flexible and save storage space, website technology development trends are used as a method for improving the performance of website-based AR.
