These days, with the advent of digital broadcasting, media environment offers users an opportunity to enjoy differentiated contents in a more aggressive fashion through user-media interactions based on computer technology. In fact, the development of contents which can induce spontaneous acts from users such as outdoor ads which use certain sensors and devices and exhibition halls has been active. With the development of low-price motion recognition devices, people have been able to enjoy diverse interaction-applied media by recognizing users' motion data without body contact. In this paper, we developed an interactive media player that can recognize the user's motion and control the video in the web service environment without installing a specific program. In addition, we set user motion recognition range and developed a user motion recognition algorithm suitable for the Leap Motion equipment installed in the kiosk. The results of this study can be experienced by various interactive media such as interactive tourism, education, and movie contents in kiosks that can be installed in public places.

Objective : The purpose of this study was to investigate the effects of an Interactive Metronome on increasing attention and impulsivity control for children with attention deficit hyperactivity disorder(ADHD). Methods : This study was conducted through the ABA'design among single-case research methods with one child with ADHD. From May to July, 2014, 3 sessions of baseline phase(A), 15 sessions of intervention phase(B), and 3 sessions of post baseline(A') were conducted. The intervention was IM training, and each session carried out short form assessment(SFA) of IM and concentration tasks. In addition, long form assessment(LFA) of IM and Self-Control Rating Scale (SCRS) were conducted at baseline, intervention and post baseline. Results : After IM training as the intervention, the participation showed an increase in attention and controled in impulsivity. After the intervention, it was demonstrated that the effects were maintained or improved in the post baseline. Conclusions : IM training can be useful for increasing attention and impulsivity control of children with ADHD. The results demonstrated the efficacy of IM training as a new approach for children with ADHD.

An interactive and iterative control panel layout method based on the constraint satisfaction problem (CSP) technique was developed to generate an ergonomically sound panel design. This control panel layout method attempts to incorporate a variety of relevant ergonomic principles and design constraints, and generate an optimal or, at least, a "satisfactory" solution through an efficient search algorithm. The problem of seeking an ergonomically sound panel design should be viewed as a multi-criteria design problem and most of the design objectives should be understood as constraints. Hence, a CSP technique was employed in this study for dealing with the multi-constraints layout problem. The efficient search algorithm using "preprocess" and "look_ahead" procedures was developed to handle vast amount of computation. In order to apply the CSP technique to the panel layout procedure, the ergonomic principles such as spatial compatibility, frequency-of-use, importance, functional grouping, and sequence-of-use were formalized as CSP terms. The effectiveness of the proposed panel layout method was evaluated by example problems and the results clearly showed that the generated layouts properly considered various ergonomic design principles.

Natural user interface (NUI) is used for the natural motion interface without using a specific device or tool like a mouse, keyboards, and pens. Recently, as non-contact sensor-based interaction technologies for recognizing human motion, gestures, voice, and gaze have been actively studied, an environment has been prepared that can provide more diverse contents based on various interaction methods compared to existing methods. However, as the number of sensors device is rapidly increasing, the system using a lot of sensors can suffer from a lack of computational resources. To address this problem, we proposed a real-time multi-device control system for natural interactive platform. In the proposed system, we classified two types of devices as the HC devices such as high-end commercial sensor and the LC devices such astraditional monitoring sensor with low-cost. we adopt each device manager to control efficiently. we demonstrate a proposed system works properly with user behavior such as gestures, motions, gazes, and voices.

In this paper, a programming system for robot-based manufacturing cell which can control and simulate manufacturing devices as well as robots in workcell is proposed and developed. The system is based on world model, and modem textual and object-level robot programming language and interactive graphic world modeler are used to construct and exploit world model. Graphic simulation is used as an efficient and easy to use debugging or verifying tool for user written robot programs. Machine dependency is minimized by adopting the hierarchical control structure and by assuming all the workcell components as virtual ones.

Holonic manufacturing system is a new approachto the organization and architecture of decentralized, autonomous and cooperative manufacturing system. The new paradigm combines the concepts of hierarchical systems and the integration of autonomous elements in distributed system. Today's scheduling and control techniques are mostly based on a centralized structure. Only little work has been done on scheduling and control of decentralized, autonomous and cooperative manufacturing system. This paper proposes a new approach IPM(Interactive Prediction Method) for scheduling and control of holonic manufacturing system.

컴퓨터 기술을 활용한 하이테크 제품의 도래는 생활에 많은 편리함을 안겨 주었지만, 제품을 조작하는 사용자들에게 '사용의 어려움'이라는 새로운 문제를 초래하게 되었다. 과거의 많은 사용자들은 제품의 구성들을 단지 봄으로써 그것이 어떻게 작동할 것이라는 것을 인지할 수 있었지만, 현재에 많은 하이테크 제품의 작동 부분들은 그 기능들이 제품 내부의 마이크로칩 속에 내장됨으로서 형태만으로 그 기능들의 용도를 이해하기란 매우 어려운 문제가 되었다.(중략)

This paper presents a novel prototype of the utility­interactive voltage source type sinewave pulse modulated power inverter using a high-frequency flyback transformer link. The proposed power conditioner circuit for the solar photovoltaic generation and small scale fuel cell has an isolation function due to the safety of the power processing system, which is more cost effective and acceptable for the small-scale distributed renewal energy conditioning and processing systems. The discontinuous current mode(DCM) of this power processing conversion circuit is applied to implement a simple circuit topology and pulse modulated control scheme. Its operation principle is described on the basis of simulation evaluations and theoretical considerations. The simulation results obtained herein prove that the proposed inverter outputs with sinusoidal waveforms and unity power factor currents are synchronized to the main voltage in utility power source grid. In this paper, the soft switching topology of high­frequency linked sinewave pulse modulation inverter is proposed and discussed.

Applying Visual Art to pop music performance is gradually increasing. A video editor which simply mixes a number of images was mainly used in the past, but now various computer software make it easy to control visual art by development of computer technology, and it became possible for you to express unique and inimitable idea as well. Compare that a complicated equipment which makes them spend much expense and time was only used in the big size of concert hall in early days, a small and simple one now helps you easily apply your idea to Visual art in Pop music performance even in the small club. The technic of Visual art is being developed gradually especially by using computer The point of this study is how to apply real-time interaction between sound and visual image to interactive media art.
