  • Augmented reality techniques have been increasingly employed in the textile and fashion industry as well as computer graphics sectors. Three-dimensional virtual clothing CAD systems have also been widely used in the textile industries and academic institutes. Motion tracking techniques are grafted together in the 3D and augmented reality techniques in order to develop the virtual three-dimensional clothing and fitting systems in the fashion and textile industry sectors. In this study, three-dimensional virtual clothing sample has been prepared using a 3D virtual clothing CAD along with a 3D scanning and reconstruction system. Motion of the user has been captured through an RGB-D sensor system, and the virtual clothing fitted on the user's body is allowed to move along with the captured motion flow of the user. Acutal fabric specimens are selected for the material characterization. This study is a primary step toward building a comprehensive system for the user to experience interactively virtual clothing under real environment.

  • In this paper, we implemented online real time strategy game using hand as the mouse in augmented reality. Also, we introduced the algorithm for detecting hand direction, finding fingertip of the index finger and counting the number of fingers for interaction between users and the virtual objects. The proposed method increases the reality of the game by combining the real world and the virtual objects. Retinex algorithm is used to remove the effect of illumination change. The implementation of the virtual reality in the online environment enables to extend the applicability of the proposed method to the areas such as online education, remote medical treatment, and mobile interactive games.

  • Currently, the world has known many innovative technologies created to bring users to interact using the internet. The latest buzzword attracting attention both from industry and academia is the metaverse. The metaverse is a virtual environment in which people used virtual reality and augmented reality devices to carry out numerous virtual activities. At first, metaverse applications were mostly virtual games, but now with advances in research, many other applications and technologies are integrating the metaverse among which manufacturing, real estate, healthcare, military, and many others. The proper operation of these applications requires some technologies like blockchain and artificial intelligence. In this paper, we investigate the role of blockchain and AI in the metaverse. This work aims to present the eventual use cases of these technologies in the metaverse regardless of their application domain.

  • As mobile augmented reality technologies are spreading these days, many users want to produce augmented reality (AR) contents what they need by themselves. To keep pace with such needs, we have developed a mobile AR contents builder (hereafter referred to as MARB) that enables the user to easily connect a natural marker and a virtual object with various interaction events that are used to manipulate the virtual object in a mobile environment so that users can simply produce an AR content using natural photos and virtual objects that they select. MARB consists of five major modules-target manger, virtual object manager, AR accessory manager, AR content manager, and AR viewer. The target manager, virtual object manager and AR accessory manager register and manage natural target markers, various virtual objects and content accessories (such as various decorating images), respectively. The AR content manger defines a connection between a target and a virtual object with enabling various interactions for the desired functions such as translation/rotation/scaling of the virtual object, playing of a music, etc. AR viewer augments various virtual objects (such as 2D images, 3D models and video clips) on the pertinent target. MARB has been developed in a mobile application (app) format in order to create AR contents simply using mobile smart devices without switching to a PC environment for authoring the content. In this paper, we present the detail organizations and applications of MARB. It is expected that MARB will enable ordinary users to produce diverse mobile AR contents for various purposes with ease and contribute to expanding the mobile AR market based on spread of a variety of AR contents.

  • 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.

  • This study suggest the development and application of the Interactive Design Toolkit as a participatory design method for general customer with the application of the Augmented Reality. The Toolkit is based on a PC-based image perception system and user can make virtual models and navigate in the virtual space by manipulating physical objects directly in real world. The toolkit can be used in the field of participatory design in systematically modularized and customizable design area including model house of apartment and system kitchen furniture. More improved design toolkit for enhancing reality and providing various Interaction method Is needed hereafter.

  • AR(Augmented Reality)는 일반적으로 VE(Virtual Environments) 혹은 VR(Virtual Reality)에서 파생한 것으로 실제 환경(real environment)에 컴퓨터 그래픽스 영상을 삽입하여 실제와 가상의 영상 혼합을 뜻한다[1]. 실세계는 컴퓨터로 만들기 힘든 많은 정보들이 존재한다. 그렇지만 그 정보들 중에 우리가 필요하지 않은 많은 정보도 있고, 때로는 우리가 필요 하는 정보가 부족할 수도 있다. 컴퓨터로 재생한 가상 환경을 이용하면, 필요하지 않은 정보들을 단순하게 만들거나 보이지 않는 정보들을 만들어 낼 수 있다.

  • Ubiquitous computing is a vision of our future computing lifestyle in which computer systems seamlessly integrate into our everyday lives, providing services and information in anywhere and anytime fashion. Augmented reality (AR) can naturally complement ubiquitous computing by providing an intuitive and collaborative visualization and simulation interface to a three-dimensional information space embedded within physical reality. This paper presents a service framework and its applications for providing context-aware u-car maintenance services using augmented reality, which can support a rich set of ubiquitous services and collaboration. It realizes bi-augmentation between physical and virtual spaces using augmented reality. It also offers a context processing module to acquire, interpret and disseminate context information. In particular, the context processing module considers user's preferences and security profile for providing private and customer-oriented services. The prototype system has been implemented to support 3D animation, TTS (Text-to-Speech), augmented manual, annotation, and pre- and post-augmentation services in ubiquitous car service environments.
