Telematic and new programming technologies support the increasing demand of education and training leading to the delivery of computer based learining systems open to distance and continuing education. Using LabVIEW, we designed and implemented an interactive learning environment for practice on electronics measurement methodologies. The environment provides remote access to real and simulated instrumentation and guided experiments on basic circuits. The environment is applied to the education and training on electronics for engineers in the field of semiconductor industry.

Since the world's first 3D commercial film with red-blue glasses was introduced in 1922, remarkable progress has been made in the field of 3D video. 3D video content gained enormous popularity with the movie "Avatar," which greatly increased the sale of 3D TVs. This momentum has weakened owing to lack of 3D content. However, the recent trend of virtual reality (VR) and augmented reality (AR) made 360 VR video and 3D games using a head mounted display wide spread. All these experiences mentioned above require wearing glasses to enjoy 3D content. Super multi-view content technology, on the other hand, enables viewers to enjoy 3D content without glasses on a super multi-view display. In this article, we introduce the technologies used to make super multi-view content, interact with it, and author content, which are developed by ETRI.

The paper deals with the implementation of prototype Ship Simulator system (VRSS) by Virtual Reality techniques with Head Mounted Display (HMD) device. The prototype VRSS was consists of PC-based human sensors, object oriented operating system. In addition, two kinds of databases arranged from Head Related Transfer Functions and 3D object models were used to create 3D sea sound, and to construct virtual world, respectively. Using the prototype system, we carried out some simulation tests for the overtaking situation to prevent collisions at sea, and discussed on the usability of the system. As results from simulations, the prototype VRSS can provide multisensory and interactive display environment. The results gave rise to the user interaction with 3D objects that give realistic reproduction of navigational environments under a given scenario. Thus, we found that the prototype VRSS should be one of the next-generation ship simulation system.

빠른 인터넷의 보급과 빈번하게 발생하는 원격지 구성원간의 협업으로 인해서 쉽고 편리하게 이용 가능한 다자간 협업 환경의 필요성이 대두되었으며 현재 이와 관련한 연구가 활발히 진행되고 있다. 커뮤니티 컴퓨팅 환경에서의 원격 협업을 지원하기 위한 구성 기술로는 먼저 지능형 원격협업을 지원할 수 있는 시스템 및 네트워킹 구조를 설계하는 기술, 다양한 종류의 입력 채널의 내용을 동시에 보여줄 수 있는 디스플레이를 제공하는 기술, 협업 구성원 간의 자연스러운 데이터 및 태스크 마이그레이션 기반 기술, 그리고 다양한 사용자 인터랙션을 제공하는 기술 등이 있다. 그러나 무엇보다도 사용자 편의성 면에서는 위치적인 이질감을 극복하고 현장감 있는 공동 작업을 지원할 수 있는 사용자 인터랙션 기술이 매우 중요하다고 할 수 있다. 본 논문에서는 이러한 인터랙션을 지원하기 위한 다양한 인터랙션 기술을 소개하며 사용자의 인터랙션이 발생했을 경우 사용자의 의도에 따라 변경된 협업 환경, 특히 공통 디스플레이 화면의 변경 정보를 사용자 컨트롤 머신에도 Graphic User Interface(GUI) 기술을 통해 제공하는 방안이 논의되어 진다.

We developed a user-friendly, interactive program to simultaneously cluster and visualize omics data, such as DNA and protein array profiles. This program provides diverse algorithms for the hierarchical clustering of two-dimensional data. The clustering results can be interactively visualized and optimized on a heatmap. The present tool does not require any prior knowledge of scripting languages to carry out the data clustering and visualization. Furthermore, the heatmaps allow the selective display of data points satisfying user-defined criteria. For example, a clustered heatmap of experimental values can be differentially visualized based on statistical values, such as p-values. Including diverse menu-based display options, QCanvas provides a convenient graphical user interface for pattern analysis and visualization with high-quality graphics.

A GIS-based regional risk analysis program to interactively study the vulnerability of bridges in a regional highway network is described. The analysis utilizes three major components. The use of a GIS system as the integrating environment to display geographic data, to handle inquiries and to display the results of a query. A risk model for bridges which can predict the level of damage due to a particular intensity of ground motion at a bridge site. A ground motion attenuation model to predict the intensity of ground motion at a particular bridge. The interactive components are supported by data files which encode characteristics such as potential earthquake sources and magnitudes, and characteristics of the bridges which are important for damage and failure analysis.

Augmented Reality integrates virtual objects onto a real world so that it extends the human's sensibility of real-world. an Augmented Reality technology combines real and virtual object in a real environment, and runs interactive in real time, and is regarded as an emerging technology in a large part of the future of information technology. So the benefits for the various businesses are estimated to be very high. In this paper, combine ARToolkit with OpenAL we can provide audio to users. These proposed methodologies will contribute to a better immersive realization of the conventional Augmented Reality system.

Augmented Reality (AR) is an emerging technology and the applications of technology are still not fully unveiled. This paper explores a new application of augmented reality for new direction in art exhibitions, which aims to bring interactive learning experience to life. The project takes printed images on book or exhibiting arts to the next level by applying AR technology to provide a unique fascinating experience to its readers on mobile devices. AR technology composing with animation brings new digital entertainment experience to the user of art exhibitions. The key feature of this paper uses the technology presents auxiliary information in the field of view of an object on art exhibitions automatically without human intervention.

In this paper, we propose an object control system on table top display to support augmented reality in which objects in real-world control computer-generated data. We developed LED-based object control system over table top display so that it is capable of controlling networked table top display. The LED-based object control system supports more natural interactive interface. In this paper, infrared LED is used to implement the object control device to be recognised by table top display. We applied LED-based object control system in air hockey game where a team has a point if their puck goes to opponent's net on a table. Since users can control objects in cyber world with the proposed object control device, it is realized augmented reality.
