Augmented Reality is a growing area in virtual reality research, The world environment around us provides a wealth of information that is difficult to duplicate in a computer. This evidenced by the worlds used in virtual environments. An augmented reality system generates a composite view for the user. It is a combination of the real scene viewed by the user and a virtual scene generated by the computer that augments the scene with addition information. The registration method represent to the user enhances that person's performance in and perception of the world. It decide the direction and location between real world and 3D graphic objects. The registration method devide two method, Model based tracking and Move-Matching. This paper researched at to generate a commerce correlation using a tracking object method, using at a color distribution and information, in the sequence scene.

The recent development in multimedia technology such as audio technology needs high quality audio system. Especially, Real Audio Technology is to be developed to play realistic sound. To meet this demands, researches on 3-Dimensional Audio which provides realistic audio effect in virtual reality and augmented reality are conducted. In this paper, how to provide realistic audio effect by using better audio technologies in augmented reality was investigated. In the study, the movements of the 3-Dimensional model on the markers were used to provide the sense of reality in virtual and real world. Namely, the sound was modified according to the movement of the model. The change in distance and angle of the model affected the sound volume and the pitch.

Networked Virtual Reality systems provide a consistent virtual world to the users, possibly ditributed across long distance, and have been widely applied in the military war game, network game. edutainment, architectural areas, and shopping mall etc. Large processing requirements. however. made these systems be mainly researched on the platforms of high-performence system graphics workstations. This study paper Presents several problems when networked virtual reality systems are implemented on commodity Internet : two problems related with 3D graphical Processing, and the other related with network bandwidth and transmission delay. We also suggest solutions to these problems and analyze their performance effect based on an architectural simulation application.

가상 증강현실은 사용자에게 사용자의 인지능력과 감각을 이용하여 현실세계를 초월한 서비스를 제공해 주는 기술이다. IT 시장조사기관인 가트너는 2017년을 이끌 '10대 전략 기술 트렌드' 중 하나로 가상현실 기술을 선정하였다. 그러나 현재 대부분의 가상현실 서비스는 시각과 청각만 의존하여 일방향으로 사용자에게 가상현실 서비스를 제공한다. 본 논문에서는 이러한 문제를 해결하기 위하여 앞으로 더 현실 같은 차세대 가상현실 서비스를 제공하기 위한 디지털 감각에 대하여 연구하였다.

증강현실은 이미 이를 이용한 다양한 서비스들이 존재하고 있고, 최근 스마트폰이 주목받으며 덩달아 부각되고 있는 개념 중의 하나이다. 기존 증강현실을 이용한 시스템에서는 객체를 증강할 때 미리 만들어진 객체를 증강하므로 객체가 증강할 당시의 주변환경의 변화가 반영되지 않는다. 따라서 증강현실을 할 때 카메라로 들어오는 현재 배경이미지와 객체가 동떨어져 보이는 현상이 발생한다. 이는 사용자가 현실세계에 가상의 물체가 올라간 것이 어색해 보여 증강현실기반의 프로그램에 몰입하는데 방해가 된다. 본 논문에서는 증강현실기반의 시스템이 사용될 때 실시간으로 주변환경의 빛 정보를 분석하여 그 정보를 객체에 반영하는 방법을 제안한다. 다양한 주변환경 중에서도 시각적으로 많은 정보를 제공하는 빛 정보를 이용하여 보다 자연스럽게 객체의 색을 보정을 하며, 이는 실시간으로 객체에 적용된다. 이는 주변환경 정보가 다양하게 바뀌는 모바일 증강현실에서 유용하게 쓰일 것이다.

The Rothschild family in the UK and the Rockefeller in the USA installed a number of private organization with which they could exert their influence on the world, recruited world renowned figured and spread out their arguments via global visual media worldwide. Their ultimate goal was to reshuffle the world in a new global order. They attempted to persuade people to accept their messages by reiterating them via their visual media. They deliver their own value of existence, efficiency and future convenience via their visual media regarding politics, economics and religion. If such is seen in a Christian perspective, they replace the place and existence of God with their own power and attempt to reorganize the world in a new global order. Their desire seems to be that of Anti-Christ, i.e. the Satan in the Bible. This study attempts to reveal that reality of visual media is fictitious from the Christian perspective.
