In this paper, the analysis and design of a motion simulator (based on the approach taken by interactive virtual reality (VR) entertainment systems) is conducted. The main components of the system include a bilateral control interface, simulation and a motion simulator control scheme. The space entertainment system uses a virtual environment that enables operators to feel the actual feedback sensing and distorted motion from the virtual environment, just as they would in the real environment. The space entertainment system integrates the dynamics of the motion simulator and the virtual environment and the operator maneuvers a steering wheel to interact with the system. The multiple bilateral control schemes employ a dynamical controller, which is designed by considering the velocity and acceleration that the operator imposes on the joystick, the environmental changes imposed on the motion simulator. In addition, we develop a calculated method to evaluate the Ratio of the simulation results. It is shown that the proposed control scheme can improve the performance of the visual entertainment system. Experiments are conducted on the virtual reality entertainment system to validate the theoretical developments.

This work has been directed at studying and developing a prototype Computer Aided Design(CAD) tool to be used for planning tendon paths in hand reconstructive surgery. The application of CAD to rehabilitative surgery of the hand is a new field of endeavor. There are currently no existing systems designed to assist the orthopedic surgeon in planning these complex peocedures. Additionally, orthopedic surgeons are not trained in mechanics, kinematics, math modeling, or the use of computers. It was also our intent to study the mechanisms and the efficacy of the application of CAD techniques to this important aspect of hand surgery. The following advances are reported here: Interactive 3D tendon path definition tools., Software to calculate tendon excursion from an arbitrary tendon path crossing any number of joints., A model to interactively compute and display the foirces in muscle and tendon., A workstation environment to help surgeons evaluate the consequences of a simulated tendon transfer operation when a tendon is lengthened, rerouted, or reattached in a mew location., It also has been one of the primary concerns in this work that an interactive graphical surgical workstation must present a natural, user-friendly environment to the orthopedic durgeon user. The surgical workstation must ultimately aid the surgeon in helping his patient or in doing his work more efficiently or more reliably.

It is expected that utility interactive small scale dispersed PV system will be widely diffused in the future. This paper discussed the design and control method of single phase PV inverter system with compensation capability of reactive power including harmonic distortion, based on state space modelling. As the results, compensation effects were suggested by simulation and experiment.

We have developed the LCD Simulator, which is called "ProLCD", in order to reduce time and efforts for the design and analysis of LCDs. We describe the numerical models implementing the computation of LC directors and electro-optics, the graphic user interface and the visualization modules. Many applications show that ProLCD is a very useful, interactive design tool with good reliability.

Due to many obvious reasons, an effort has been made for a long time by naval architects to develop mathematical hull forms or to express them mathematically. As a part of such effort, this program has been developed, applied in actual design works and proved to be a powerful tool of generating ship hull in the preliminary design stage.

In this paper we propose a multi-step approach for interactive design development based on usability engineering and show the proposed methodology is able to apply the digital art works. As an example, we show the proposed multi-step approach is efficient in the developing process of a digital design works.

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)

인터넷은 일반 초보자들이 사용하기 쉬운 정보검색 도구의 개발, 상호작용이 가능한 멀티미디어 환경, 다양하고 무한한 정보와 쉬운 정보창출 등과 같은 장점 때문에 지속적인 성장을 하여왔다. 인터넷이 실험매체로서의 모색단계에서 벗어나 본격적인 매체로 성장하고 있는 가운데 기존 4대 매체(신문, 잡지, TV, 라디오)에 이어 제5의 매체로 서서히 자리 매김을 하여 가고 있음을 의미하며 이는 기존 매체의 대중 전달과는 달리 'one-on-one' 매체라는 인터넷의 특징이 광고의 패러다임 전이를 요구하고 있는 것이다.(중략)

The music with the times, evolved from analogous tape music to digital music. New authoring tools, interfaces, and applications make us to produce high quality music using cheap equipments. Inspired by this concept, we design an classical chinese style-instrument with the audio-visual interactive function. It enables a user to compose music and to see a vivid picture at the same time.

Analyzing and simulating of today's complex electrical networks require the use of computer-aided engineering tools. In recent years, the rapid advances in micro-computer hardware technology have increased the availability of power application software on the personal computer, once the domain of mainframes and minicomputers, enabling efficient and cost-effective power system analysis. An interactive simulation and analysis software for a power system is developed and presented in this paper. The software is written in PASCAL and is designed for PC use. This paper presents an integrated software package to run PC-DOS for the analysis of electric power networks. The software is menu driven and controlled by prompts. These programs are intended to help users understand the process of power system analysis and design.
