Terrain Generation

This paper presents an application that allows the generation of virtual terrains interactively, using augmented reality markers. This application also allows the user to navigate in the generated virtual environment. To demonstrate how the process is done, a terrain generation scenario was chosen. Virtual objects were augmented using markers and the detection is done through the ARToolKit framework. A particle system was used to simulate deformation to better incorporate the needs of terrain generation. The deformation itself follows an interparticle force between the particles attached to a movable physical marker and the particles attached to a fixed multi-marker representing the mesh. A viscous force is also used to generate a plastic material effect ensuring permanent deformation. The resulting application although conceptually simple and easy to use, can produce an immersive output environment that the user can freely navigate.

As If

Augmented reality is defined as the technology in which virtual objects are blended with the real world and also interact with each other. Although augmented reality applications are used in many areas, the most important of these areas is the field of education. AR technology allows the combination of real objects and virtual information in order to increase students’ interaction with physical environments and facilitate their learning. Developing technology enables students to learn complex topics in a fun and easy way through virtual reality devices. Students interact with objects in the virtual environment and can learn more about it. For example; by organizing digital tours to a museum or zoo in a completely different country, lessons can be taught in the company of a teacher as if they were there at that moment. In the light of all these, this study is a compilation study. In this context, augmented reality technologies were introduced and attention was drawn to their use in different fields of education with their examples. As a suggestion at the end of the study, it was emphasized that the prepared sections should be carefully read by the educators and put into practice in their lessons. In addition it was also pointed out that it should be preferred in order to communicate effectively with students by interacting in real time, especially during the pandemic process.

The Revolution

Along with the development, the application can be used as a medium for learning. Augmented Reality is a technology that combines two-dimensional’s virtual objects and three-dimensional’s virtual objects into a real three-dimensional’s  then projecting the virtual objects in real time and simultaneously. The introduction of Solar System’s material, students are invited to get to know the planets which are directly encourage students to imagine circumtances in the Solar System. Explenational of planets form and how the planets make the revolution and rotation in books are considered less material’s explanation because its only display objects in 2D. In addition, students can not practice directly in preparing the layout of the planets in the Solar System. By applying Augmented Reality Technology, information’s learning delivery can be clarified, because in these applications are combined the real world and the virtual world. Not only display the material, the application also display images of planets in 3D animation’s objects with audio.

The method presented in this work reduces the frequency of virtual objects incorrectly occluding real-world objects in Augmented Reality (AR) applications. Current AR rendering methods cannot properly represent occlusion between real and virtual objects because the objects are not represented in a common coordinate system. These occlusion errors can lead users to have an incorrect perception of the environment around them when using an AR application, namely not knowing a real-world object is present due to a virtual object incorrectly occluding it and incorrect perception of depth or distance by the user due to incorrect occlusions. The authors of this paper present a method that brings both real-world and virtual objects into a common coordinate system so that distant virtual objects do not obscure nearby real-world objects in an AR application. This method captures and processes RGB-D data in real-time, allowing the method to be used in a variety of environments and scenarios. A case study shows the effectiveness and usability of the proposed method to correctly occlude real-world and virtual objects and provide a more realistic representation of the combined real and virtual environments in an AR application. The results of the case study show that the proposed method can detect at least 20 real-world objects with potential to be incorrectly occluded while processing and fixing occlusion errors at least 5 times per second.

In this paper the outcome of a project is presented that aims to modify and improve one of the most widely used Augmented Reality tools. Augmented reality (AR), is a fast growing area of virtual reality research. Augmented Reality (AR) is a newly emerging technology by which user’s view of the real world is augmented with additional information from a computer model. ARToolKit is one of the most widely used toolkits for Augmented Reality applications. The toolkit tracks optical markers and overlays virtual objects on the markers. In the current version of the toolkit the overlaid object is stationary or loops regardless of the optical target position, this means that the overlaid object cannot be animated or changed based on the movement of the optical target. The aim is to improve the toolkit, therefore a design solution to modify it were designed and implement so that users can manipulate the position of the overlaid virtual object, through movements of the optical target. The design solution focuses on developing a mathematically based links between the position of the optical target and the overlaid virtual object. To test the solution test cases were developed and the results show that the design solution is effective and the principal idea can be used to develop many applications in different sectors such as education and health.

Abstract The research aims to develop mobile learning media with augmented reality for electrical measurement instruments. The learner can use this application to improve their skills and knowledge about using electrical measurement instruments correctly. One of the essential skills for electricians is using voltmeter, ammeter, and ohmmeter. The result of measuring they can do some analysis about an issue or troubleshooting the electrical field. From the development research, was produced learning media application product was named ARAVO. ARAVO is an abbreviation of augmented reality of Ammeter, Voltmeter, and Ohmmeter. ARAVO helps learners and even lecturers to simulate the use of electrical measuring instruments by combining virtual objects such as multimeter with the real world. Thus will provide a more visible visualization of how to use electrical measuring instruments before they practice directly with actual measuring instruments. ARAVO is a mobile application that can run on the smartphone platform mobile Android. Into the development of this application must go through several stages before it is ready for use.
