This Audio-Visual Interactive Installation is composed of a video projection of a video Projection and digital Interface technology combining with the viewer's voice recognition. The Viewer can interact with the computer generated moving images growing on the screen by blowing his/her breathing or making sound. This symbiotic audio and visual installation environment allows the viewers to experience an illusionistic spacephysically as well as psychologically. The main programming technologies used to generate moving water waves which can interact with the viewer in this installation are visual C++ and DirectX SDK For making water waves, full-3D rendering technology and particle system were used.

최근의 웹을 기반으로 한 소셜 네트워크 서비스의 발전은 사회관계 형성 서비스를 넘어 광고 마케팅 및 SNS 오픈마켓 등의 상업적 이용으로까지 사용되고 있으며 Facebook Live와 같은 개인방송의 영역까지 확장되고 있다. 인터넷을 통한 온라인상의 사회관계는 노화와 질환으로 외출이 어려운 노년층에게 지역사회 및 친구들과의 의사소통을 가능하게 할 뿐만 아니라 인터넷을 통한 정보 활용으로 생활의 질을 향상시키고, 노후를 즐길 수 있는 방법을 찾는 데 도움을 줄 수 있다고 알려져 있다. 하지만 대부분의 웹서비스는 복잡한 사용자 인터페이스를 제공하고 있으며 익숙하지 않은 기기를 사용하는 것은 노년층에게 쉽지 않기 때문에 노년층은 제한된 콘텐츠만을 제공받게 되어 정보화 사회에서 소외될 가능성이 있다. 이에 본 논문에서는 웹 접근성을 향상시킨 소셜 콘텐츠 서비스 Photo Alive! Demo EasyFace를 소개한다. 또한 노년층이 다루기 어려웠던 키보드와 마우스를 벗어나 새로운 조작 기기들로 웹 서비스를 이용할 수 있도록 구현하였다. MINIX Remote Control, Mirroring, EasyFace Control Application 세 가지의 조작기기 작동 방법을 구현하여 노년층에 맞춤화 된 새로운 사용자 인터페이스를 제안하고자 한다.

The virtual reality(VR) technology can provide various stimuli, including, visual and auditory stimuli, simultaneously in the virtual environment and encourage the user to interact. Virtual reality is a set of computer technologies, which when combined, provide an interactive interface to a computer generated world. In this world the subject can see, hear and navigate in a dynamically changing environment in which he participates as an active player, by modifying the environment according to his will. Moreover, the subject can get a feeling for the virtual environment in much the same way as one feels real life situations. In the real world, a plethora of information from various modalities may be in conflict, and modulate each other to form an illusion. In this study we investigated whether a tactile illusion on a real hand could be evoked by a virtual stimulus, the time required to generate this illusion and its duration. This study shows that the illusion occurred, and that was correlated with presence score in the virtual environment.

Recently researches about multi-modal system has been studied widely and actively, Such multi-modal systems are enable to increase possibility of HCI(Human-computer Interaction) realization, enable to provide information in various ways and also enable to be applicable in e-business application, If ideal multi-modal system can be realized in future, eventually user can maximize interactive usability between information instrument and men in hands-free and eyes-free, In this paper, a new multi-modal browsing system using Java RMI as communication interface, which integrated by HTML browser and voice browser is suggested and also English-English dictionary search application system is implemented as example.

Today, the world is facing overflowing digital technology, floating digital contents in the air, and various perspectives on the contents, and these are called new media waves. The waves show diverse features applied in arts and interior designs. In the new media world, a process that shows what artists and designers are dreaming of, planning, and presenting is becoming important., Therefore, a purpose of this research is to understand and refine the concept of new media world, and is to study on presentations of new media art in commercial spaces. Up to present times, New media art is a metaphor in the air, which connects digital art and design. Like the modifier "NEW" contains meaning of frequent changing, new media art has various characteristics in the commercial areas. First, new media art shows lighter and various space-designs with numerous lights and colors through the evolution of interface between substances and non-substances. Second, new media art has liquidity of spaces that come with diverse communication and change though infinite possibilities of digital technology. Finally, new media arts has amusement itself based on virtual images through interactive reality extension from human experience.

This Study is focused on hedonic model study for retargeting advertising Based air inteface using useful information. many research related to the existing Internet of things, relatively not many study for effective advertising model based air inteface. So, this study is designed more information, fun, interactive advertising model based air inteface. therefore, result of this study show that implication to produce advertising based air inteface provides a practical guide.

In this paper, we review relevant technologies of Mixed Reality(MR) and show important components of perspective that can overcome technical limitations of the current MR. An MR technology combines real and virtual objects 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(IT). We've grouped the major obstacles limiting the wider use of MR technologies into three themes: technological limitations (i,e., tracking, rendering, authoring, and registration), user interface(UI) limitations(i.e., UI metaphor for MR interaction), and social acceptance issues.

A grid-connected photovoltaic (PV) system comprised of multicrystalline silicon (mc-Si) modules was installed in a cold climate region in the U.S. This roof-mounted stationary PV system is a real-world application of PV for building energy generation in International Energy Conservation Code (IECC) Climate Zone 5 (and possibly similar climate zones such as 6, 7 and 8), and it served the purposes of research, demonstration, and education. The importance of this work is highlighted by the fact that there has been less emphasis on solar PV system in this region of the U.S. because of climate and latitude challenges. The system is equipped with an extensive data acquisition system capable of collecting performance and meteorological data while visually displaying real-time and historical data through an interactive online interface. Experimental data was collected and analyzed for the system over a one-year period with the focus of the study being on measurements of power production, energy generation, and efficiency. The annual average daily solar insolation incident upon the array was found to be $4.37kWh/m^2$. During the first year of operation, the PV system provided 5,801 kWh (1,264 kWh/kWp) of usable AC electrical energy, and it was found to operate at an annual average conversion efficiency and PR of 10.6 percent and 0.79, respectively. The annual average DC to AC conversion efficiency of the inverter was found to be 94 percent.

The paper proposes a new protection algorithm for reliable operation of grid-interfaced PV system, which can flexibly interact with conventional protective schemes of power utility grid not only to prevent damages to utility or public persons and utility apparatus caused by malfunction or failure in distribution network protection system, but also to protect a PV system itself from faults or abnormal conditions of the network. The proposed algorithm is based on reclosing characteristics of the distribution system. As a network fault occurs, the new scheme determines whether it is momentary or permanent and responds in a pre-programmed way to the fault. For permanent outage, the proposed algorithm shuts down inverter's operations but monitoring system voltage and frequency at the point of common coupling with grid. When it comes to the momentary outage, Inverter starts stand-by operation mode so that it can be automatically connected to the grid without start-up procedures as soon as the system voltage and frequency returns into the normal operation range. In order to investigate' and evaluate the PV system operation, simulation study based on PSCAD/EMTDC has been carried out to verify the performance of the proposed protection scheme.
