UI design is growing in meaning and form itself through the development of hardware and contents. And it makes users accept its interface as a extension of the body and mind because of the substantial rapport of the user and contents with developing of device and graphic. In this study, we analyzed user interface in a view of digital storytelling by observing of its role within user and contents. Not only this, classifying and investigating story elements in the games for forming the theoretical basis of storytelling UI are enforced. For the case study of UI, we choose the game, Diablo, Half-Life, and Homeworld because the game is suitable for the application of node-type storytelling and effectively uses graphic and input unit. This analysis explains the interface has the contents data that divided or shared and it means the interface performs its part of story nodes, which are extracted from the story, and choice. And we analogized that the story elemental can be substituted and used practically for interface because the stories made through the thing that users and developers are in the space of coexistence by the interface. Storytelling UI will be a good way to make a most intriguing piece as a joyful spontaneous complex that use story node. It is worth by reason of making by user and discovering live inner story so that it can approach to the substance of the story.

The development of computer-integrated design systems that fully support structural design process needs the computerization of structural design at the preliminary design stage. The objective of this paper is to develop a prototype system for preliminary design of reinforced concrete structures. This study focuses on the development of a natural design process oriented GUI(Graphic User Interface) and a representation of an experienced knowledge. The prototype system has been currently implemented using the objected-oriented programming concepts, the program language(i.e.,Visual C++) and the expert shell(i.e., Intelligent Rules Element).

In this paper, an approximate optimization program based on GUI(graphic user interface) environment is developed. This program is coded by using Fortran and Visual basic. Fortran is used to Progress approximate optimization process. Visual basic is used to make user environment for user to use conveniently. Inside of this program, it uses two independent programs. One is commercial program, ANSYS, and the other is optimization program, PLBA(Pshenichny-Lim-Belegundu Arora). The former is used to obtain approximate equation of stress and displacement of a structure. The latter is used to solve approximate optimization. This algorithm uses second-order information of a function and active set strategy. This program is connecting ANSYS and PLBA. And it progress the process repeatedly until it obtain optimum value. As a method of approximate optimization, sequential design domain(SDD) is introduced. SDD starts with a certain range which is offseted from midpoint of an initial design domain and then SDD of the next step is determined by optimal point of a prior step.

As increasing emphasis is being placed on user experience design, the RIA technology is widely deployed for user interface and software operation on embedded devices including cell phones and TVs. In particular, RIA-based IPTV enables creation of various interactive contents via sophisticated animation and various input devices. This paper proposes a service framework for emotional contents on broadcast and communication-converged IPTV systems. We design a programming interface extension for IPTV-based flash contents and develop a prototype of flash runtime with the extended programming support. Since the proposed runtime was carefully designed to fully utilize the built-in graphic acceleration hardware in media processor, it supports high resolution graphic animation in resource-constrained IPTV environments.

FPSO is widely used to develop deep sea oil fields and HHI has constructed ten(10) FPSOs. During these constructions, relevant structural design criteria such as yielding, buckling, fatigue, collision and impact strength were applied to verify structural safety. To apply the buckling strength evaluation for structures, the critical buckling stresses and applied stresses of relevant panels should be calculated. The plate and stiffened panels are to be idealized, which are needed much time and efforts by designers. Therefore, program development is necessary in order to evaluate the buckling strength conveniently and accurately. In this study, the buckling strength assessment system by using offshore code, DNV-RP-C201 was developed under MSC/PATRAN, pre-post program of finite element method. Graphic user interface program is written in MSC/PATRAN PCL functions. Source program to evaluate the buckling strength is developed in FORTRAN programming languages. The developed program is verified by comparing with the results of the Nauticus Hull developed by DNV Classification Society, and applied to the marine construction project conducted by Hyundai Heavy Industries LTD.

An ubiquitous environment has been developed in order to allow users to use information more easily. These environments are based on advanced development of mobile ubiquitous hardwares. Currently, a various user interfaces are developed for mobile ubiquitous devices using the graphic or voice. In this paper, propose a specialized graphical user interface which is based on analysis of a user profile. This user interface can provides suitable interface for individual users using XML information on the small screen of mobile ubiquitous devices.

Objective: The present study was to improve the graphic user interface (GUI) of a military computer-based training (CBT) system in terms of usability. Background: Existing studies have focused on usability evaluation of a particular GUI type such as sequence, hierarchy, or context type; however, few research has been conducted which identifies preferred GUI features based on a comparative analysis of different GUI types. Method: A comparative evaluation was conducted by 9 CBT design experts using a 7-point scale (1: very low, 4: neutral, and 7: very high) on hierarchy and context GUI types of a military CBT system in terms of 10 usability criteria. Then, preferred features of the hierarchy and context types being accommodated, a new GUI was developed and validated by 22 CBT users. Results: While the hierarchy type was found preferred by 1.6 times in terms of controllability to the context type, the opposite was found in terms of attractiveness, simplicity, and responsiveness by 0.6, 0.8, and 0.8 times, respectively. The proposed GUI was found superior to the hierarchy and context types in terms of accessibility and informativeness by more than 1.5 times, but inferior to the hierarchy and context type in terms of simplicity by 0.6 and 0.9 times, respectively. Conclusion: The new GUI developed by accommodating the preferred features of the hierarchy and context types improves usability in terms of accessibility and informativeness except simplicity. Application: The comparative analysis of various GUIs can be applied to develop an improved GUI in a systematic manner based on preferred features of the existing GUIs.

The purpose of this study is to develop a PC-based water supply facilities information system. This system will be a major stepping-stone for developing Geographic Information Systems(GIS) in Korea, which is constructed by integrating the technologies related to Automated Mapping(AM) systems and Facilities Management(FM) system. And the results of this study are as follows: (1) After the user needs assessment, it was decided that information management of the water supply facilities including distribution pipes, valves, and leaking management are the most urgent tasks. So, the system was developed focusing on these tasks. (2) After the system design and development, the water supply facilities information system consists of graphic database management system, attribute database management system, internal interface that links graphic data and attribute data, and graphic user interface for user-friendliness. (3) The graphic data and the attribute data including distribution pipes, leading-pipes, valves, and parcels at the study area, Non-Hyun Dong Kang-Nam Gu in Seoul, were used in this system, and the water supply facilities database was established. It was applied to test these facilities, and proved that the system developed in this study is efficient to manage information within the scope of this study. (4) The function using the parcel identification number was efficient to locate the address concerned.
