The study goal is to develop the user interface design principles to improve the usability of university course management systems. To achieve the goal, a usability study was conducted using a survey questionnaire and usability test. Eleven user interface design principles for university course management system were developed based on the usability study. This study has significance in that student opinions were incorporated directly into the user interface design principles of university course management system.

By the help of computer graphics and rapid development of hardwares. GUI(Graphic User Interface) represented by WYSIWYG(What You See Is What You Get) changed user interface from liguistic model(e.g : command, etc.) to spatial model(e.g : pulldown menu, scroll bar, icon, itc.). This graphical user interface model for the ship conceptual design(MBASWIN) adopted event-driven programming technique and object-oriented concepts. Different from traditional design programs, MBASWIN is separate from the design program completely and controls all design modules. This enable a designer to accomplish a flexible designs.

Graphical user interface design, the visual language to convey information about the icon and the user's information is a medium that can lead to action. Graphical user interface to communicate with the user icon, the user is easy to use, so any time you want to provide information effectively. Communication in order to increase the efficiency of the Graphic User Interface on the nature of the medium must be made to develop the appropriate icon. In this research icon of the type of icon painting. A picture of the icon representation of each type of detail, according to a rating of johyeongjeok identify the elements of the correlation between. On the type of representation of each of Art and Design elements that I know what I saw. The icon design based on user preferences provide guidance on the direction of design-oriented. When the data can be used to designs based on the theory has to offer.

At the beginning stage of design process, the concept design is required to equip the creative idea thinking and exerts critical effect on the success of production. To support the idea thinking process at the stage of concept design, web-based Creative Group Thinking System(CGTS) was developed. In this vein, the purpose of this study is to investigate the significance of HCI(Human Computer Interface) and UI(User Interface) and to find the way to increase the applicability of the UI of CGTS.

In the research of HCI (Human-Computer Interaction), we always use the GUI（graphical user interface） of graphics input devices until we invent TUI (tangible user interface) which is used to control the computer by hand-touching or other subjects. In this study, we investigate and classify several TUI for the most part in business with the theory and concept of Tangible Bits by Hiroshi Ishii & Brygg Ullmer in order to research the development of TUI.

The purpose of study is to investigate the current user interface level of air traffic control system with the usability analysis and satisfaction survey questionnaire on user satisfaction. Think aloud protocol is used to identify not only task analysis, but also the level of user-friendliness of the FIMS and ASDE system, and the user interface questionnaires was conducted by QUIS. We collected data from 6 controllers for Think aloud protocol and 15 controllers for QUIS in Incheon airport. The results showed that the system was the valuable tool for ensuring human performance with the support of memory and the facilitation of decision-making tasks. It helps air traffic controllers perform better and minimize errors in a congested time. The human-computer interface system design, however, was not applied, which led to the increase of workload. Air traffic controller participation in software development provided excellent examples for applications in terms of software in FIMS. Based on these results, the study provided that the usability of system interface was necessary to take into account human factors. The development and design of system was discussed in User Interface environment.

Mobile web applications are different from desktop web applications because of their small screen size and small user input devices. Therefore user interface designers have spent their effort and time to re-design the user interface of mobile web applications to meet these differences. In this paper, we introduce five user interface patterns for mobile web applications to reduce their effort and time. Two of them are for utilizing small screen size efficiently, and they are space overloading pattern and data filtering pattern. These patterns enable designers to reduce screen usage. The other three patterns - data suggestion pattern, input reuse pattern, and incremental data input pattern - are for helping users' data input on mobile devices. These three patterns enable users to reduce direct data input. Our work will help user interface designers develop mobile web interface to utilize screen space efficiently and get data with less errors and less efforts from users.

Flexible display interface is capable of creating new user behaviors based on its characteristics of outstanding surface representation and display transformations such as bending, rolling, and folding. Thus, it is being discussed that the newly emerging flexible display interface can offer a different user experience that the previous flat display couldn't. However, as it is hard to find studies that identify the general attributes of user experience in the area of flexible display research, this study was intended to identify and label experience that users expect in a flexible display interface. For this purpose, this study first investigated literature reviews about user experience in previous digital media interface and flexible display interface and conducted interview research in order to reflect the users' perception, collecting 52 items that represent user experience. In addition, these items were used as measurements to deduct different types of user experience, and 308 interviewees participated in the interview research process. As a result, 10 types of user experience were developed from the results of the survey: functionality, understandability, pleasure, convenience, familiarity, stimulation, adaptability, collectivity, reality, and aesthetic.
