Owing to supply of smart phones and the diffusion of SNS, the number of peoples who are living, linked with us, is incomparably more than in the past. The continuous communication is essential in maintaining good relationship, so peoples have no choice but to seek for most efficient communication method in order to maintain good relationship. This thesis intended to advise how to construct next generation immersive multi-media system, using augmented reality and MPEG-V that have come to the fore recently. In addition, the SNS platform service of new type was suggested in this thesis, in connection with the pairing service. Now, we can create a town in a specific space like the real world, if we utilize the augmented reality that became possible by SNS service and we can talk and exchange informations in that space. This system would provide various services peoples wish to have, interlocking experiences through five senses like sense of vision, sense of hearing, sense of touch and etc..

A lot of games are supposed to play through controller operations, such as mouse and keyboard rather than user's physical movement. These games have limitation that causes the user lack of movement. Therefore, this study will solve the problems that these traditional game systems have through the development of a motion-producing system, and provide users more realistic system. It recognizes the user's position in a given space and provides a mobile augmented reality system that interacts with virtual game characters. It uses augmented reality technology to make users feel as if virtual characters exist in real space and it designs a mobile game system that uses armband controllers that interact with virtual characters.

Natural interface is important to select and provide the services in ubiquitous smart space such as u-plant, u-distribution. Augmented Reality(AR) has recently begun to receive attention as a realization tool for natural interface. AR provides virtual object on real environment and it differs from virtual reality. When AR is used, it has advantage to provide information intuitively and collaboratively. However AR is rarely used in e-commerce domain of ubiquitous smart space, and it has limitation which predefined information and services provide in a static manner. Hence, the purpose of this paper is to propose a methodology of AR based e-commerce which provides personalized association service by considering user's dynamic context. To do so, association algorithm is developed based on Rescorla-Wagner model and Galton's free association test.

This study purposed to interpret subjectivity, which centers on the concept of virtuality embedded in the process of virtualizing contextual awareness and mixing the boundary between realities and virtual realities for renewing the feeling of time and space represented by augmented realities in daily spaces, from the viewpoint of traditional media. By explaining how the reflection of reality is exposed focusing on immediacy and hypermediacy from the viewpoint of media remediation, we found that, different from conventional media, augmented reality enables the screen to function as a part of subject and play a role and, by doing so, converts it to the complete subject of digital media comprehending observers and operators.

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.

Having pet is one of the activities people living in modern society do to relieve stress and find peace of mind. Currently, the object of companion animals has moved beyond being a real 'living entity' and has developed to a stage where the animal's upbringing process can be enjoyed in a virtual space by being programmed in digital content. This paper studies detailed elements such as character design, interaction, and realism of 'Tamagotchi (1996)', which can be said to be the beginning of digital training content, and 'Peridot (2023)', a recently introduced augmented reality-based training content. The point was that it was training content using portable electronic devices. However, while the environment in the electronic device in which Tamagotchi's character exists was a simple black and white screen, the environment in which Peridot's character operates has been changed to the real world projected on the screen based on augmented reality. Mutual communication with characters in Tamagotchi remained a response to pressing buttons, but in Peridot, it has advanced to the point where you can pet the characters by touching the smartphone screen. In addition, through object and step recognition, it was confirmed that the sense of reality had become more realistic, with toys thrown by users on the screen bouncing off real objects. We hope that this research material will serve as a useful reference for the development of digital training content to be developed in the near future.

A core technology for implementation of Augmented Reality is to develop a merging algorithm between interesting 3-D objects and real images. In this paper, we present a 3-D object recognition method to decide viewing direction toward the object from camera. This process is the starting point to merge with real image and 3-D objects. Perspective projection between a camera and 3-dimentional objects defines a plane in 3-D space that is from a line in an image and the focal point of the camera. If no errors with perfect 3-D models were introduced in during image feature extraction, then model lines in 3-D space projecting onto this line in the image would exactly lie in this plane. This observa...

As one of applications in augmented realities, this paper presents a bubble popping system utilizing a haptic vibro-tactile mouse. In this system, virtual bubbles randomly float in the 3D space. By using the vibro-tactile mouse grabbed by a user, the bubbles are popped when they are touched by the mouse in the 3D space. Then a bubble popping effect with addition mouse vibration is delivered to the user's hand through the mouse. The proposed system is developed on ARToolkit environment. Therefore, basic components such as a camera and a marker pattern are required. The systems is composed of a vibro-haptic mouse, a webcam, a marker pattern, a graphic bubble object, and graphic mouse. Mouse vibration as well as bubble fade-out effect is delivered. Therefore, the combination of visual and tactile bubble popping effects outperforms the usage of a single effect in the experience of augmented reality.

Augmented Reality (AR) is a useful technology for various industrial systems. This paper suggests a new playground system which uses markerless AR technology. We developed a virtual playground system that can learn physics and kinematics from the physical play of people. The virtual playground is a space in which real scenes and CG are mixed. As for the CG objects, physics of the real world is used. This is realized by a physics engine. Therefore it is necessary to analyze information from cameras, so that CG reflects the real world. Various games options are possible using real world images and physics simulation in the virtual playground. We think that the system is effective for education. Because CG behaves according to physics simulation, users can learn physics and kinematics from the system. We think that the system can take its place in the field of education through entertainment.

In general, virtual reality (VR) and augmented reality (AR) are technologies used to overcome the limitations of space and time in human communications. Currently, VR and AR companies are mostly developing contents for a single user. However, it is expected that there will be a need for sharing experiences among two or more users in a VR/AR environment. In this paper, we investigate the trends in remote collaboration technologies for VR/AR that allow two or more users to share video, voice, and gestures, as well as emotions. We will also discuss the future of such technologies.
