In this paper, we propose a reflective augmented reality (AR) display system based on integral imaging (II) using a mirror-based pinhole array (MBPA). The MBPA, obtained by punching pinholes on a mirror, functions as a three-dimensional (3D) imaging device, as well as an image combiner. The pinhole array of MBPA can realize a pinhole array-based II display, while the mirror of MBPA can image the real objects, so as to combine the images of the real objects with the reconstructed 3D images. The structure of the proposed reflective AR display is very simple, and only a projection system or a two-dimensional display screen is needed to combine with the MBPA. In our experiment, a 25cm × 14cm sized AR display was built up, a combination of a 3D virtual image and a real 3D object was presented by the proposed AR 3D display. The proposed device could realize an AR display of large size due to its compact form factor and low weight.

Notice: a peer-reviewed version of this preprint has been published in Behavior Research Methods and is available freely at http://link.springer.com/article/10.3758/s13428-018-1162-0Continuous Flash Suppression (CFS) is a popular method for suppressing visual stimuli from awareness for relatively long periods. Thus far, it has only been used for suppressing two-dimensional images presented on-screen. We present a novel variant of CFS, termed ‘real-life CFS’, with which the actual immediate surroundings of an observer – including three-dimensional, real life objects – can be rendered unconscious. Real-life CFS uses augmented reality goggles to present subjects with CFS masks to their dominant eye, leaving their non-dominant eye exposed to the real world. In three experiments we demonstrate that real objects can indeed be suppressed from awareness using real-life CFS, and that duration suppression is comparable that obtained using the classic, on-screen CFS. We further provide an example for an experimental code, which can be modified for future studies using ‘real-life CFS’. This opens the gate for new questions in the study of consciousness and its functions.

Reality Increasing or often also called AR (Augmented Reality) in English, is a technology that can add two-dimensional or three-dimensional illusions of objects together into a 3D into the real world then project illusion objects into real time. Unlike the illusion of reality where in the real world is completely replaced, reality only adds to or completes reality. Augmented Reality unites real objects and illusions into real circles, works interactively in real time and found integration between objects in 3D and good integration requires effective investigation. Web AR provides Web-based access using Augmented Reality through a web browser using a combination of technologies including WebRTC, WebGL, WebVR, and Modern APLs sensors. Catalogs are publicity tools used by companies as a way to promote their products and services. Examples of companies that use catalogs are Furniture stores that promote products. Here it will be visualized into 3D until it looks more clear and attractive to consumers. So, based on the description above, the author takes the title "Implementation of Augmented Reality with Marker Method as Media Catalog in AR-Based Furniture Stores. Keywords: Augmented Reality, WEB AR, catalog

Abstract The full-chain system performance characterization is very important for the optimization design of an integral imaging three-dimensional (3D) display system. In this paper, the acquisition and display processes of 3D scene will be treated as a complete light field information transmission process. The full-chain performance characterization model of an integral imaging 3D display system is established, which uses the 3D voxel, the image depth, and the field of view of the reconstructed images as the 3D display quality evaluation indicators. Unlike most of the previous research results using the ideal integral imaging model, the proposed full-chain performance characterization model considering the diffraction effect and optical aberration of the microlens array, the sampling effect of the detector, 3D image data scaling, and the human visual system, can accurately describe the actual 3D light field transmission and convergence characteristics. The relationships between key parameters of an integral imaging 3D display system and the 3D display quality evaluation indicators are analyzed and discussed by the simulation experiment. The results will be helpful for the optimization design of a high-quality integral imaging 3D display system.

The use of robotic models with the main functionalities of real objects together with the implementation of innovative technologies, augmented reality (AR) in this case, is the focus of the paper. Therefore, the concept of a simplified robotic model (SRM) is presented. This concept is important because it is useful for achieving the goals of engineering projects, which is especially justified prior to the construction of the real objects. It improves presentation, development, and education capabilities that are unavoidable segments of the project strategy. Additionally, it is possible to transfer developed solutions to the final objects after certain modifications. Multidisciplinary building of the unique SRM of the 3-axis centrifuge for pilot training is described, where multi-attribute decisionmaking is used to conduct some experiments. The application includes the use of a physical model, built from LEGO elements, software for controlling and monitoring the physical model, and an AR mobile app.

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.

Augmented Reality adalah sebuah teknologi yang relatif baru dan masih dikembangkan sampai saat ini. Konsepnya adalah menggabungkan dimensi dunia nyata dengan dimensi 'dunia nyata' yang termediasi, atau dunia virtual, untuk menciptakan kesan bahwa dimensi dunia nyata kita diperkaya dengan objek maya tiga dimensi. Hal ini dilakukan dengan cara 'menggambar' objek tiga dimensi pada marker, yakni sebuah 'pola' dalam bingkai segi empat yang bersifat unik dan dapat dikenali oleh aplikasinya. Aplikasi yang bersangkutan menerima input berupa video stream, yang berarti menggunakan input berupa citraan dari perangkat keras yang berfungsi menangkap gambar, biasanya sebuah webcam. Karena berupa video stream, artinya gambaran yang ditangkap sebagai input akan berubah-ubah, dan program harus dapat tetap mengenali marker meskipun berubah posisi dan orientasi relatif terhadap perangkat input. Pengenalan terhadap posisi dan pergerakan ini adalah salah satu konsep Teknologi Informasi yang bernama Computer Vision, dan digunakan untuk mendeteksi pola pergerakan relatif objek terhadap kamera.Pendidikan terhadap anak harus dilakukan sedini mungkin terutama dalam hal kesehatan. Seiring dengan berkembangnya pemahaman masyarakat tentang pentingnya kesehatan gigi, banyak pihak yang telah memberikan informasi terkait kesehatan gigi di berbagai media. Tidak hanya orang dewasa yang menjadi sasaran akan tetapi juga mulai dari anak-anak sudah dikenalkan dengan pengetahuan tersebut. Karena dibutuhkan media penyampaian untuk anak maka banyak bermunculan media edukasi yang diharapkan bisamendidik anak dengan berbagai macam cara..Pemanfaatan Augmented Realitysebagai alat untuk mengedukasi anak, ini akan memberikan pandangan baru terhadap media edukasi yang ada pada saat ini, bukan hanya menggunakan objek secara nyata tapi juga bisa digunakan objek berbentuk virtual dalam penyampaian informasi. Nilai tambah dari media ini adalah mempermudah penyampaian dan membuat informasi semakin menarik terutama bagi anak.Augmented Reality is a technology that is relatively new and still being developed today. The concept is to combine real-world dimensions to the dimensions of the 'real world' are mediated, or the virtual world, to create the impression that the dimensions of the real world we are enriched by virtual three-dimensional objects. This is done by 'drawing' a three-dimensional object on the marker, which is a 'pattern' in a rectangular frame that is unique and can be recognized by the application. Pertinent application accepts input in the form of a video stream, which means using the input in the form of images of the hardware image capture function, typically a webcam. Because the form of a video stream, meaning that as the input image captured will vary, and programs must be able to recognize the markers remained unchanged despite the position and orientation relative to the input device. Introduction to the position and movement is one of the Information Technology concept called Computer Vision, and is used to detect object movement patterns relative to the camera.Education of children should be done as early as possible, especially in terms of health. Along with the development of public understanding about the importance of dental health, many people who have provided information related to dental health in a variety of media. Not only adults who were targeted but also start from the children has been introduced with such knowledge. Because it takes delivery of media for children then many emerging medium of education is expected to educate children with a variety of ways.Utilization of Augmented Reality as a tool to educate the child, this will provide a new perspective on media education that existed at this time, instead of just using the real object but also can be used in the form of a virtual object in the delivery of information. The added value of this medium is to facilitate the delivery and make the information more interesting, especially for children.

In recent years, Augmented Reality has become a very popular topic, both as a research and commercial field. This trend has originated with the use of mobile devices as computational core and display. The appearance of virtual objects and their interaction with the real world is a key element in the success of an Augmented Reality software. A common issue in this type of software is the visual inconsistency between the virtual and real objects due to wrong illumination. Although illumination is a common research topic in Computer Graphics, few studies have been made about real time estimation of illumination direction. In this work we present a low-cost approach to detect the direction of the environment illumination, allowing the illumination of virtual objects according to the real light of the ambient, improving the integration of the scene. Our solution is open-source, based on Arduino hardware and the presented system was developed on Android.

Augmented reality applications in tourism usually use images as markers, such as brochures or information boards. However, it is still ineffective because users cannot interact directly with real-objects. This study aims to create applications that more interesting and interactive way which can be used by interacting directly with real-object. This research is located in Taman Ayun Temple, one of the tourism objects that are world cultural heritage in Bali. The application is designed with the real-object tracking augmented reality method using the Wikitude Android SDK platform. The application is built in Indonesian and English. The test results show that the percentage of the recognition of 40 objects from various directions is more than 80%, from a distance of 10 to 40 meters is more than 70%, from a good and moderate lighting condition is more than 80%, and recognize similar objects as a different object.
