오늘날 기술 경쟁이 심화되면서 업체간 기술 격차는 큰 차이를 보이지 않고 있다. 그래서 각 기업들은 자사 제품의 경쟁력 확보를 위해 다양한 분야를 연구하게 되었고, 그 결과 소비자들에게 높은 기술력을 제공하는 것보다는 새로운 경험을 제공하는 것에 대한 중요성이 점점 부각되어 가고 있다. 그래서 본 논문에서는 PC 에서 웹 서비스(Web-Service)를 사용하는 사용자의 경험을 IPTV 에서도 경험할 수 있는 방법에 대해 연구하였고, 그 중 사용자들이 좀더 편리하고 쉽게 웹을 경험할 수 있는 Widget UI를 제안한다. 우리가 제안하는 IPTV 에서 웹 서비스를 제공하는 Widget UI 는 서로 독립적인 Widget 서비스들로 구성되어 있으며, Widget 서비스의 개수와 배치는 사용자에 따라 다르게 제공된다. 즉, 우리는 IPTV 를 위한 사용자 맞춤형 웹 서비스 제공 Widget 사용자 인터페이스를 제안한다. 또한 각 Widget 서비스의 정보 검색은 리모컨의 4 방향 키를 사용하도록 제공함으로써 사용자에게 사용의 편리성을 증대시키고 학습 피로를 감소시킬 수 있다. 이러한 학습 편의성과 사용 편리성을 사용자에게 제공함으로써 기존에 IPTV 에서 사용하기 힘들었던 웹 서비스의 사용성을 크게 향상 시키는 효과를 기대할 수 있다. 우리는 이러한 Widget UI 의 사용성을 객관적으로 평가하기 위해 UI 전문가들을 대상으로 전문가 평가를 실시하였으며, 결과 비교를 위해 다른 웹 서비스 제공 UI 들도 추가적으로 전문가 평가를 실시하였다. 전문가 평가 결과 본 논문에서 제안한 Widget UI 가 타 UI 들에 비해 높은 사용성 평가를 기록하였으며, 이 결과는 결국 우리가 제안한 Widget UI 가 IPTV 에서 웹 서비스 정보를 제공하는데 있어 효율적이고 적합한 방식임을 보여준다.

This study is about an interface design supporting collaborative learning activities in online environment in which people exchange their knowledge and give feedback on personal storytelling to each other. Interface design issues from the viewpoint of Computer Supported Collaborative Learning (CSCL) on digital media design are considered. Based on collaborative learning theories and analysis on the existing online collaborative sites about digital media, such as online forums for digital pictures and films, interface guidelines are suggested and the interface is designed. The interface design is evaluated through a pilot test. The interface for collaborative learning on personal storytelling is designed to support observation and to provide a scaffolding for valuable conversation. It is also designed to help intersubjectivity of online conversation and an easy access to media.

The purpose of this study was to identify problems of usability and to improve an interface in the digital textbook for leaner's leading to self-directed learning. To address those goals, the theory of affordance, which was related to affordance as leading to behavior, was applied for analyzing the user interface of digital textbook. Also, 10 students, 4th grade elementary school, were participated in the study. Participants were reported affordance's problems of digital textbook through Human Computer Interaction. As a result, some affordance's problems of the digital textbook were found out as follow; difficulty of page clicking, too small touch button, confusing the button, and, need to specific guidance. Based on the result, some suggestions were recommended to improve usability of digital textbook.

This paper describes the design of image data transmitter for portable media device for Mobile Display Digital Interface standard. The transmitter uses connection lines to 6 to transmit QVGA image data. In this paper, the transmitter is using only 9 packets for image processing and a state-machine based design is adapted for packet processing. The design was verified using FPGA Xilinx virtex4-LX60. Data rate of the transmitter is 363Mbps with six connection lines. The transferring capability is 30 frame of 24bit RGB 500,000 pixel image data per second.

Digital technology in modern society is entering the era of digital convergence and ubiquitous computing, and is playing an important role to overcome the limitation of time and space. Based on new media method's rapid application development, a wide range of forms as digital design is made possible. A large part of our living such as information sharing, collaboration, production, recreation, working and various social activities has been realized from the space that digital media offer. As we see a much broader range, the digital media's diverse expressions affect, in interactive ways, not only the relationship between humans and things, between each individual human, and between humans and the environment, but also even emotional purification and realm of educational, cultural, and social aspect. In this study, the aim is to discuss the user-centered design considered for integration into the interaction space design method and is to concentrate on research on. Focusing on digital media, user-friendly interface features of the space environment, construction and utilization of digital media have been applied to try to analyze the interaction effect of space that is created for the design and application of various applications and will seek ways. Thus, various case-studies have been explored where interface space is developed, creating virtual reality through cognitive basis and 3-D interface space. For example, emotional expressions are embedded for the space of commerce, education and exhibition, enabling intercommunication through haptic interface, with changing sound and visual effects which are caused by the movement of people in a certain space. With consideration of the relationship between physical environment and objects, interactive design should be achieved by providing a human oriented interface based on social, cultural and environmental aspects.

Various kinds of digital contents developers are recognizing the importance of interface design, but they have no integrated and arranged interface design principles, so are facing difficulties in applying them. About the interface of web-site which is one field of the digital contents, there came out necessary principles about the interface design to some extent by the active studying activities in and out of the country. However, the researchers are proposing various principles, so it is difficult to apply which design principle in what situation. To this, this study looks into the common design principles while comparing and analyzing the design principles of Donald A. Norman, Jakob Nielson, Jeff Johnson and Manna Sjoberg. Based on this, we suggest 10 interface design principles to improve the functionality and aesthetics of the digital contents.
