Thanks to the development of IT technology, there have been developed a variety of types of portable music players. IT technology didn't stop there, however. It has gone to developing GUIs (Graphic User Interfaces) to deliver more information to the user. As the function of GUIs has become important, the music players are being required to show characteristics of the sounds they output visually beyond just delivering the sounds through analyzing the information that the sounds contain. To visualize the information of sounds, that is to say, has become substantial. In this process, sound graphic equalizers have been developed in order. The object of this study is to produce a new sound graphic equalizer with new forms of expressing visual images of sounds besides the bar graphs, in which user feedback is possible. This study has devised a new sound visualization form in visually expressing the information of sounds by analyzing their characteristics. This new sound visualization provides a sound graphic equalizer with which the user can select images for the information of the sounds s/he listens. This study suggests a new alternative GUI with which the user can change the form of the outputted images in realtime as communicating with the player.

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.

During several years, lots of industrial and individual products have been developed based on the text or graphic LCD module which has been gave the short developing period to the developer. With the advent of home networks and intelligent robots, the need for interaction between human and instruments has been increased. Recently, goods with a TFT-LCD come out. But in spite of a simple required performance, the complicated microprocessor, such as ARM processor, is required to interface the TFT-LCD and touch screen. Our research and development is to develope an embedded TFT-LCD module in order to use or apply to the goods through the simple interface by the general users as well as the developers. We adopt the RTOS(real time operating system) in order to operate TFT-LCD independently and various communication protocols are provided in order to offer the simple interface to users and developers.

GIS is a powerful toolbox in managing spatial data associated with attribute data. However GIS is short of spatial analysis function and graphic user interface(GUI) function in dealing with dynamic planning problems. Decision Support Systems(DSS) make up for the shortage of GIS by providing GUI function, modeling function and database function. Spatial Decision Support Systems(SDSS), a new kind of DSS, incorporate display function, basic spatial analysis function and manipulation function of spatial data and attribute data of GIS and GUI function, modeling function and database function of DSS in dealing with spatial planning problems. Planning Support Systems(PSS) add more advanced spatial analysis function and intertemporal function to the functions of SDSS. This study focuses on the modeling of a PSS for capacity expansion of water-distribution network depending upon land use planning by using GIS, value engineering(VE) and life cycle costing(LCC). The PSS shows a guideline about the investment of water-distribution networks related to urban growth management through generating certain numbers of dynamic alternatives to supply the amount of water caused by land use planning.

This paper describes how to implement reporting system for web-based information system. Reporting system is the S/W module that user is able to produce output of data in formal format. In Client/Server system, remote user can make formal output with client-side reporting component module. This client reporting component is usually system dependent. With web based information system, intranet, evolving, this client/server system need to he migrated to web-based reporting system. Reporting system component support multi-processing and real-time text/graphic output of server data. Ant Client can save or pint web page of client module. Especially, for real test its function and user interface, this reporting component is adopted in real network management system. The result shows that this reporting system component is very smart and excellent for real time web based monitoring system.

In order to support simple authoring an application of augmented reality for diverse users, the process for the object registration comprised of tracking and recognizing the object should be accomplished intuitively and simple. Although many 3D reconstruction methods to be applied to the object registration have been developed, the methods have not beyond the experimental level yet. In this paper, we proposed a novel marker-based tangible interfaces for various users to manipulate the object with intuitive and simple approaches during an authoring applications fo augmented reality. The proposed method make use of marker as intuitive interface to obtain 3D geometric information of 3D reconstruction. 3D geometric information of an object surface is acquired by touching the object directly with the proposed tangible interfaces. The tangible interfaces not only support 3D reconstruction for graphical modeling but also offer features information which is used for augmented reality. Finally, we verify efficiency of the proposed method with demonstration of an augmented reality application using the proposed method.

With the help of the advancements in information and communication, information appliances are changing. Flat panels made it possible for information appliances to become smaller in size and lighter in weight, and high end graphics provide increase in realistic and immersive use. Even with these advancements interest in design for laboratory equipment tend to only stay on a level of the exterior of the equipment, not to the point of designing the interface of display GUI. Inspired with the problem above this research would contain the preference analysis ondisplay GUI design considering the characteristics of the main users and the laboratory equipment itself. The test would be held through comparison of graphic-based display GUI and text-based display GUI and analyzing the task time and number of errors made, looking for which display GUI scientist prefer. The test results show that text-based GUI has a higher efficiency but the actual users preferred the graphic-based display GUI.

This paper presents a digital video broadcasting - terrestrial (DVB-T) receiver system based on the orthogonal frequency division multiplexing (OFDM) modulation method, which has exhibited a good reception performance even with obstacles and a mobile reception. As such, an improved OFDM receiver is developed for a DVB-T system that also considers function expansion for further development. After manufacturing the DVB-T receiver system, the performance of the proposed system is compared with three other hardware systems, all of which are end products. The experimental results confirm the performance using the measured minimum required carrier-to-noise ratio and threshold of visibility signal for each system. In addition, a graphic user interface (GUI) and electronic program guide (EPG) are developed for the digital television user.
