With the increased market demand for advanced specifications in smart phones, smart phones that have functions with wireless communications with high speed, cameras with high pixel and with high graphic processing ability have appeared. Furthermore, as traditional Augmented Reality technology has been practicable in mobile devices, many application's use AR technology, so AR's portability has been increased. But application with AR technology, which was implemented in smart phones has created capacity issues as applications are taking up a large portion of the memory capacity of phones. This research designed and implemented optimized AR technology by Mixare, AR open source, to solve such problems. As a result, I assured that there has been a decrease in application's memory used on the basis of mobiles.

교육의 질이 향상됨과 동시에 학습 콘텐츠의 질 역시 향상되고 있고 어플리케이션, AI, AR 등 다양한 기술들과 접목된 다양한 교육 방식들이 존재하게 되었다. 이와 함께 스마트폰의 기술 발달과 보급률 증가에 따라 다양한 기술들과 접목된 교육용 어플리케이션들에 대한 접근 또한 쉬워지고 있다. 이에 본 논문에서는 유아의 학습 능력을 조사하여, 단어 학습에 있어 의미파악, 단어 인지, 바른 발음 지도 등을 길러 줄 수 있도록 AR 기술을 접목한 교육용 AR 어플리케이션을 설계하고 이를 구현하였다. 본 논문에서 개발한 어플리케이션은 유아의 인지와 학습 방법을 토대로 하여 바른 발음과 철자를 지도하고, 단어 학습에 있어 낱말이 가진 의미파악을 도와주며, 반복학 습을 통하여 단어를 인지하고 사용할 수 있도록 도와준다. 본 논문의 어플리케이션은 AR 기술을 융합하여 이미지만을 사용한 교육보다 쉽게 의미를 파악하는데 도움을 줄 수 있고 이에 따라 인지 능력도 상승시켜 줄 것이라 기대한다.

Recently, many ICT companies are trying to expand the ecosystem of VR (Virtual Reality) and AR (Augmented Reality). They are developing a variety of industries such as entertainment, education, e-commerce and so on. There is also contains the power, energy field. And application related with VR/AR will increase in power industry. Thus, Platform is necessary because there are problems such as re-use, interface with legacy system and security. We can expect the convenience and efficiency by developing VR/AR power platform. In this paper, we will discuss the trends of VR/AR technologies, possibilities of VR/AR in energy field, essential elements of VR/AR power platform. In the future, we expect to lead standards of VR/AR in energy and to develop a killer application such as Pokemon GO.

This paper is a study on map contents to be embedded in a new type of mobile device that combines 2D information and 3D information by combining 2D information with augmented reality technology. We also describe the planning and production of a 3D map application called 'NSU AR Map' using Unity3D engine to help understand this paper. 'NSU AR Map' is a map application that enables accurate identification of user's location and real-world view through 360 View. Based on the experience gained during the process of 3D map application, this paper will present how 3D technologies and augmented reality technologies are applied to new map applications and how they can be developed in the future.

모바일 디바이스와 스마트 글래스의 확산/보급으로 다양한 AR/VR/MR 어플리케이션이 출시 되었으나, 사용자들이 일반적으로 가정에서 많이 사용하는 대형 Display인 TV에서 이용할 수 있는 AR/VR/MR 어플리케이션은 거의 없는 실정이다. TV 디바이스에서 이러한 영상처리 기법을 이용하려면 별도의 카메라나 CPU가 필요한데, 이를 이용하기 위해 사용자들이 별도의 투자를 하기 어렵기 때문이다. 본 논문에서는 사용자에게 가장 친숙한 모바일 디바이스와, 디지털 TV신호를 수신하기 위한 STB를 연동하여 다양한 AR/VR/MR 서비스를 이용할 수 있는 방법을 제안하고 실제 시스템 구현과 실험을 통해 제안된 방법의 품질 및 실시간성 향상을 검증한다.

Recently, researches on augmented reality(AR) are actively being conducted, and on addition of AR in social network system has become a necessity. In this paper, we propose GPS-based AR system for social network. This proposed system adds the recent check-in coordinates by automatically synchronizing a friend list in facebook and represents those added location coordinates in a real-world environment by using AR. Marker-based AR system that was commonly used by existing users consumes too much storage space and processing frequency for driving handle devices. But, location-based AR application can solves the disvantages of the standard marker=based AR system. Therefore, this proposed system allows an user with iOS hand devices to use GPS-based AR system by automatically searching the optimal speed for wifi and 4G. This will improve social network service.
