Augmented reality is a technique for combining virtual images into real life by showing information of virtual 3D objects on top of a real-world environment (Azuma et al., 2001). This study is an augmented reality-based educational content delivery device that receives user input that selects either a preset object or a photographed object for augmented reality-based training; It includes a three-dimensional design generation unit that generates a stereoscopic model of the augmented reality environment from an object, a three-dimensional view of the scene, a disassembly process of the developing road from a three-dimensional model, and a content control unit provided by the user terminal by generating educational content including a three-dimensional model, a scene chart, a scene, a decomposition process, and a coupling process to build a coupling process from the scene to the three-dimensional model in an augmented reality environment. The next study provides a variety of educational content so that children can use AR technology as well as shapes to improve learning effectiveness. We also believe that studies are needed to quantitatively measure the efficacy of which educational content is more effective when utilizing AR technology.

The system using augmented reality can save the time and cost. It is verified in various fields under the possibility of a technology by solving unrealistic feeling in the virtual space. Therefore, augmented reality has a variety of the potential to be used. Generally, multimodal senses such as visual/auditory/tactile feed back are well known as a method for enhancing the immersion in case of interaction with virtual object. By adapting tangible object we can provide touch sensation to users. a 3D model of the same scale overlays the whole area of the tangible object; thus, the marker area is invisible. This contributes to enhancing immersive and natural images to users. Finally, multimodal feedback also creates better immersion. In this paper, sound feedback is considered. By further improving immersion learning augmented reality for children with the initial step learning content is presented. Augmented reality is in the intermediate stages between future world and real world as well as its adaptability is estimated more than virtual reality.

As the cyberspace several decades ago created a cyber fiction fever, the augmented reality as the future of imagination can generate another kind of literary genre and new social ambiance where books tend to come to life more realistically. This newly created "smart fiction," "smart movies," and "smart environment" will be full of fun, hopes and conveniences. But addiction to smart kinds will create unwanted dangerous plethora like ghost-like avatars, wild animals and Farid due to the limitations of human control over hi-technology. If so, the adventures we plan to take will turn fantasy into horror in no time. Instead of loving new scientific things blindly, the emphasis hereafter must be put rather on the potentially negative aftermaths of the new innovative technology. Some viewers after watching the film Avatar are still suffering from the syndrome called "avatar blues," a homesick for Pandora. After their experiencing of the experimental 3D effects in books and media, audience and readers are required to actively deal with the increased lack of the darker cave which the comparatively unsatisfactory present can never fill with fixity and limit. Like the prevention against the addictive online game or the manual of 3D television or 3D printer, the extreme off-limits and safety zone for this virtually and expendably subverting technology must be seriously reviewed by community before using and adopting it. Also, these technologically expanded and augmented environments must be prudently criticized by the in-depth study of literature just as cyber space begun by Gibson's cyber fiction and its criticism.

Purpose: This study examined the needs for asthma education programs as perceived by school-age children, parents, and teachers and investigated parents' and teachers' expectations for incorporating augmented reality (AR) in asthma education. Methods: This descriptive, cross-sectional study included 339 participants: 125 school-age children, 132 parents, and 82 teachers. Data were collected from children, parents, and teachers on the need for asthma education, the requirements for asthma education, and the expectations of parents and teachers for incorporating AR in asthma education. Data were analyzed using descriptive statistics, the t-test, analysis of variance, and the Scheffé test. Results: Asthmatic children and their peers, parents, and teachers all felt there was a significant need for education about asthma, with education on how to deal with an asthma attack being needed the most. The incorporation of AR programs in asthma education was viewed positively by both parents and teachers. Conclusion: An AR children's asthma education program should be developed in which children with asthma and their peers, parents, and teachers can participate together. Furthermore, it is expected that children with asthma will independently undertake more effective disease management after attending an AR asthma education program.

Children are by nature curious and enthusiastic about learning and love to explore and search for everything they see around them, but as a result of this exploration they may sometimes be exposed to dangerous situations ranging from falls to poisoning and suffocation. That is why when supporting a child's natural desire to explore the world and supporting his awareness of dangerous situations and good handling of them, helps him build a conscious scientific mind and enhance his curiosity in the natural world. It is not easy to imagine a difficult situation in which we or one of our family is in danger, unable to help ourselves or to help them in time, due to our complete ignorance of the rules of first aid. Hence the importance of learning first aid not only for the child but for the community and the world at large. "Hakeem" is an Arabic E-health educational application that aims to teach children from the age of six to eleven years first aid, in our belief that the seed of renaissance lies in the care and education of children, and the lack of Arabic content that aims to teach children first aid skills. The idea is to create a scenario in which the child is responsible for saving the person who will be in a dangerous situation using Augmented Reality (AR) technology, to increase engagement and interaction and provides a rich user experience, and according to the child's performance, he will get reward points. The game will have several levels: Beginner, Intermediate, and Hakeem, and based on the player's points he will get a title and move to the next level, and when he reaches the end, he will get the certificate.

The aim of the paper is to present an object recognition method toward augmented reality system that utilizes existing education instruments that was designed without any consideration on image processing and recognition. The light reflection, sizes, shapes, and color range of the existing target education instruments are major hurdles to our object recognition. In addition, the real-time performance requirements on embedded devices and user experience constraints for children users are quite challenging issues to be solved for our image processing and object recognition approach. In order to meet these requirements we employed a method cascading light-weight weak classification methods that are complimentary each other to make a resultant complicated and highly accurate object classifier toward practically reasonable precision ratio. We implemented the proposed method and tested the performance by video with more than 11,700 frames of actual playing scenario. The experimental result showed 0.54% miss ratio and 1.35% false hit ratio.

요즘 어린이 교재들은 예전에 비한다면 급속도의 발전을 이루고 있어서, 앞으로도 다양한 컨셉과 아이디어로 계속 발전될 경향이다. 하지만 현재까지의 보통 낱말카드나 그래픽들은 2D로 이루어져 있어서 현실감이 떨어지는 교육이 되는 경우가 많다. 그렇다고 현실감을 주기 위해 어린이들이 갖고 놀도록 커다란 3D 의 장난감들을 갖게 된다면 이들이 차지하는 공간은 너무나 많아진다. 사실 아이들이 있는 가정들을 보면 공간의 부족 때문에 갖고 있던 교재나 장난감들을 버리기도 하는 것이 요즘 현실이기 때문이다. 본 논문은 이런 문제점들을 보완하기 위해 AR(Augmented Reality)Toolkit[l]을 응용한 어린이 교재를 제안한다 공간절약형으로 정육면체 패턴을 만들어 공간절약도 되고, 이 패턴(pattern) 위에서 3 차원 영상도 보고 패턴을 교체해 가면서 다양한 재미도 느낄 수 있는 교재를 구현해 보고자 한다.
