This research provide the basic information to enhance the user-orientedness of usability design guidelines for software products and an effective empirical guidance to classify design attributes of internet shopping mall sites. The results of analysis show that design attributes can be classified into the procedural attribute group, the shopping tool attribute group, the visual attribute group, linguistic attribute group, and others. The results show that shopping tool attribute group can be divided further into the search tool attribute group and purchase tool attribute group and that the visual attribute group can be divided further into the screen condition attribute group and the character legibility attribute group. The research reveals that when designers design software interfaces and features they should take the compound effect of a group of design attributes into consideration to enhance the usability of the system.

S/W의 구성은 기능을 실제로 수행하는 계산처리부와 사용자와 정보를 주고받는 User Interface부로 크게 나누어 볼 수 있다. 대부분의 S/W는 그 기능의 충실도와 아울러 편리한 사용법이 잘 어울려야 제역할을 할 수 있다. 따라서 편리한 User Interface를 만드는 일은 훌륭한 기능을 제공하는 것과 마찬가지로 S/W 개발자들이 지향해야 할 목표중 하나라 하겠다. 그러나 편리한 User Interface를 만드는 일은 전체 시스템개발 기간중 상당한 부분을 차지한다. 특히 CAD/CAM관련 S/W와 같이 사용자와 정보를 Graphic으로 주고받는 경우에는 User Interface의 구성이 더욱 더 어려워지며, 개발기간중 User Interace가 차지하는 비중은 더욱 커지게 된다. GUI는 최근들어 상당히 각광을 받고 있는 분야이며, 상당수의 GUI가 개발되어 있고, 이중 Unix용의 X-Window MS-DOS용의 MS-WINDOWS 3.0이 널리 사용되고 있다. 그러나 이러한 Window System들은 매우 다양한 기능을 제공하고 있음에도 불구하고, GUI자체의 덩치가 매우크고, S/W개발자가 익혀야하는 내용이 너무 복잡하여, 중/소형의 S/W개발에 사용하기에는 적합하지 않다. 본 연구에서는 GUI(Graphic User Interface)부분을 계산처리부와 완전분리하여, 범용성있는 개발용 Tool Kit을 구성함으로써 S/W개발자는 계산처리부만을 만들면되는 방안을 제시하고 있다. GS-GUI는 Menu처리부, Mouse/Keyboard입력처리부, Text/Graphic출력처리부로 나뉘어진다. Menu처리부는 Menu File로 주어지는 Menu Tree를 Pop-Up형태로 보여주며 User가 Menu를 선택할 수 있도록하며 선택된 Menu Item에 대한 Action Code를 계산처리부로 넘겨준다. 입력처리부에서는 Mouse와 Keyboard 어느것으로나 입력이 가능하도록 해준다. 출력처리부에서는 Action Code에 따라 계산처리부에서 계산된 결과를 화면에 보여주기 위한 각종 2D/3D Graphic Routine들이 포함되어있어 계산처리부에서 불러쓰도록 되어있다.

Natural user interface (NUI) is used for the natural motion interface without using a specific device or tool like a mouse, keyboards, and pens. Recently, as non-contact sensor-based interaction technologies for recognizing human motion, gestures, voice, and gaze have been actively studied, an environment has been prepared that can provide more diverse contents based on various interaction methods compared to existing methods. However, as the number of sensors device is rapidly increasing, the system using a lot of sensors can suffer from a lack of computational resources. To address this problem, we proposed a real-time multi-device control system for natural interactive platform. In the proposed system, we classified two types of devices as the HC devices such as high-end commercial sensor and the LC devices such astraditional monitoring sensor with low-cost. we adopt each device manager to control efficiently. we demonstrate a proposed system works properly with user behavior such as gestures, motions, gazes, and voices.

Digilog Book, the next generation publication material, supplies digitalized contents on an analog book by integrating digital contents into existing analog books. There are some studies related to authoring tools which are to authorize, and publish some books which provide digital contents by using VR or AR techniques. In this paper, a pen-type haptic user interface for Digilog Book authoring tool has been introduced. This haptic user interface is developed for more realistic and more effective authoring tasks. This haptic interface provides haptic effects for authoring tasks which are including translation, rotation, scaling, and menu selection. In this research, we designed a body, control circuits, vibration haptic patterns for haptic user interface, and a protocol for between haptic user interface and Digilog Book main control system. Also a simple user study has been done with a developed haptic user interface.

In light of the recent advancement in networking and information technology, the direct information request through website has increasingly proven to be the preferred means over visiting physical archives. Thus, the proper utilization of a communication tool capable of sufficiently capturing user feedback and requests is an absolute necessity. This paper examines the availability and utilization of alternative user participatory communication tools in government websites with particular focus on the archives in South Korea, the United States, the United Kingdom, Canada, China, and Japan. In assessing the use of alternative user participatory communication tools in these archives, we examined the availability of communication mediums other than the online forums, email, and telephone with particular focus on social media tools that may offer a degree of familiarity for the user. Our research indicates that the most frequently utilized social media tool is Facebook while the archive offering the greatest variety of alternative user participatory communication tools was the United States archive.

The goal of this research is a visual and auditory tool development enabling designers to have the same emotional value with users in the process of user centered design. Through the research, we intend to show the aid measure for making cognitive gaps narrow between users and designer in the process of transforming and understanding the emotional needs as a verbal image. because In the business practice of design, most of tools and techniques for assessment and analysis of emotional needs are those used usually in the marketing fields. So the information generated and transformed from users to designers have a form of physical words. When the designer's understanding of the emotional needs is considered as a product mediated communication process, the morphologic and cognitive information gaps become obvious. This difference could be a false basis in designing with emotional user needs. So the alternative needs assessment sub-tools of visual and auditory information form was embodied mainly for designer's cognitive gaps and inter-cultural emotional needs assessment. As the method of embodiment, Firstly, adjectives related to emotion were classified in their cognitive dimension. Secondly, visual and auditory data were extracted, and then the relativity verified. Finally, the practicality and effectiveness were tested through the database generation. In view of the results so far achieved, 1. We could find being of the big information cognitive gaps in the verbal assessment of emotional needs between designers and users. 2. With the visual and auditory assessment tool, we could make the big cognitive gaps narrower than we expected. 3. Also, we could find the chance that the fidelity, recognition, and friendliness of design for emotional user needs would become better.

In the domain of IS, game was used as a tool to enhance the results of decision making, education and more. In another stream of research, researchers focused on revealing the motive of people playing games. This study focuses on the effect of the tool; increased accessibility via mobile, to online game using patterns and behaviors. Due human reaction towards competition, technology acceptance and the online game's gambling traits, it is expected that the increased mobile accessibility (tool) will increase and intensify the game playing behavior. Also, it is expected that the in-game purchase will increase as well. In depth interview with both game service providers and players is planned to confirm that the mobile version acted as a tool to increase accessibility, rather than a additional game. Survey along with an interview is to be conducted to find relevant play and spending patterns if they are to exist.

Two government affiliated research institutes, EDUMAC and AURI, are developing some tools for an user participating design process in public recently. The tools are originated from DQI/DQIfS, launched in 2002 by CIC(Construction Industry Council) in U.K.. At the beginning DQI/DQIfS was not a tool for making a decision but for a communication between layman and experts of architectural process. Because of this intent the most crucial thing is not DQI/DQIfS itself but how to use the tool: CIC is trying to develop various ways of facilitation. Domestic situation is no exception. Without a proper tool there were an independent user participating process in 2001 and it must have been the first participating process in architectural discourse. Through the seven workshops, the users of Namhansan elementary school drew not only the vision of the school but also concrete requirements which have been continuously adopted so far. The aims of this paper to analyse two facilitation processes: DQI/DQIfS in U.K. and the case of Namhansan process. Even not a proper tools for the process there was a spontaneous facilitation in Namhansan process. When we make a comparison between the Namhansan process and the DQI/DQIfS process there are considerable similarities in terms not only of the process itself but also the results. It shows that there are possibilities to make a Korean facilitation in a user participating process and this study must be the first step.
