On this study, we researched differences between 2D and 3D with principle of GUI with the estimate that the user interface will be changed to 3D and we figured out the special feature of 3d-GUI through 3 ways, Autonomy, Interaction and Presence. Based on this theory research, we also had a survey with difference of 3d and 2d GUI to forecast the possibility of 3d-GUI for the main user interface of the future media contents and finally found out its marketability as an ideal interface.

이동통신 단말기의 그래픽 유저 인터페이스 환경은 다양한 요인에 의하여 그 변화를 자극 받고 있다. 한정된 디스플레이 공간 안에서의 다 기능화로 인한 사용성의 문제, 정적이고 지시적인 상황에 익숙한 문자 중심의 세대에서 자율적이고 동적인 영상 중심의 세대로의 사용자 세대의 변화, 합리적 소비 보다는 감성적 만족을 중요하게 여기는 사용자 가치의 변화, 그래픽 디자인 트랜드의 변화, 서비스 컨텐츠의 변화, 기술의 발전 등 이동통신 단말기를 둘러싼 모든 측면에서 변화가 진행되고 있다. 여기에 이동통신 단말기 제조사, 서비스 업체, 컨텐츠 업체, 칩 제조사 등 이동통신 서비스와 관련된 다양한 사업 주체들의 복잡한 이해관계 속에서의 경쟁 또한 이러한 변화를 부추기는 요인의 하나로 볼 수 있다. 본 연구에서는 이러한 변화요인들을 적절히 수렴하여 제공할 수 있는 보다 효과적인 그래픽 유져 인터페이스 디자인 방법을 모색하고자 하였으며, 보다 효율적이고 적극적인 개선을 위해 현재 이동통신 단말기의 GUI 디자인의 주요 디자인 수단인 Bitmap 또는 Vector 그래픽 대신 보다 다양한 시각적 표현 방법을 내재하고 있는 3D 기반의 Motion 그래픽을 활용한 이동통신 단말기의 GUI 디자인 방법을 제안 하고자 한다. 하지만 아직 여러가지 제약 조건들로 인하여 이동통신 단말기 내에서 3D Motion 그래픽의 적용이 완전히 자유롭지 않은 것이 사실이다. 그러나 기술의 발전 속도로 볼 때 머지 않아 3D Motion GUI 제공을 위한 이동통신 단말기의 기술적 환경은 충분히 발전될 것이며, 이에 따라 본 연구와 같이 3D 그래픽이나 Motion 그래픽을 등을 활용한 이동통신 단말기의 사용자 인터페이스 연구의 선행은 매우 필요하다고 볼 수 있다.

The touch screen phone launched domestically in Korea, unlike the existing plane UI, it applied a cubic shape of 3D UI which provides three dimensional solid graphic. This study proposes to examine the correlation between the users' experience of 3D GUI, which were made by two different companies, and the brand. From this point of view, this study sets up a hypothesis about intimate correlation between individual differentiated brand and the user experience. Base on that, a model was designed. This study measured the satisfaction of user experience through the disclosure and non-disclosure of brand, focusing on 3D GUI cases which were launched so far, and it demonstrated that there was a clear difference in the degree of satisfaction. Through this examine, a brand was confirmed as one of the important element of user experience in using the 3D GUI that was launched competitively by companies. Therefore, the result of this study suggest that the designers need to establish strategies that make the brand as the core subject of design during the process of manufacturing product and service.

Despite the fact that the mobile environment has favorable conditions for using data contents, it is not easy to implement enhanced data services for mobile broadcasting based on MPEG-4 BIFS. With a structure inherited from VRML, BIFS targets different types of content with a development approach that is not very compatible with broadcasting contents. Furthermore, it is not easy to implement BIFS because the standard is too complicated for the mobile broadcasting environment. Accordingly, this study proposes an enhanced mobile TV contents model that provides interactive 3D objects and GUI for the viewers to interact with the broadcasting contents. By applying the model to the DMB environment, this study suggests a direction for future developments of mobile broadcasting contents. In order to represent 3D graphics on mobile TV, we analyzed MPEG-BIFS 3D nodes and composed a subset of VRML profile, and defined new nodes that can efficiently represent GUI at the content development level. If this study helps facilitate expression of 3D graphics and interactions in data contents composition, enhanced efficiency of contents development is expected to promote the development of various contents suitable for the mobile broadcasting environment.

With the recent development of 3D printers, there is a growing need to make them similar to real products. As a result, FDM full-color 3D printers have been developed and actively distributed, but GUI design has fallen short of that, causing confusion among users. Accordingly, this study conducted a literature survey, and through a case study, the current status of FDM full-color 3D printers was identified and the components of GUI design were analyzed based on prior research. The draft checklist was drawn up according to the components of the derived GUI design, and 24 items were deleted through the three Delphi surveys and the validity of the remaining 26 items was verified. As a result, the layout should consist of intuitive screen configuration and menus with high frequency of use, and the text should be intuitive and clearly communicated. In addition, the icon should be placed in a visible position and used in real life to image it. Finally, we could see that the color should be used to give feedback to the user using the highlight color and not overlap the output.

In order to enhance the productivity of mobile and develop reliable software, the test of mobile application software should be required absolutely. The most important way to communicate to users has been used to GUI. But GUI test method in mobile has no the test automation system except manual test by checklist. In this paper we present a test method and tool by image flow to reduce the time required and finds out errors to GUI, by carrying out the study on automatic GUI testing tool based on image flow to GUI test of mobile application.

Recently, the most mobile application software developers are being faced by short developing time (fast time-to-market), various requirements and requirement changes. In order to overcome the environment, developer should support user friendly GUI and assure the quality from the early developing process using GUI test method. This paper proposes a test method and tool for mobile software GUI, which reduces test time and supports comfortable test environment by user oriented UI design. We implemented a tool based on test scenarios based image flow for high testing accuracy and test case reusability. And the results show the characteristics of the method compared to the existing tools.

Indoor location-based services provide a service based on the distance between an object and a person. Recently, indoor location-based services are often implemented using inexpensive depth sensors such as Kinect. The depth sensor provides a function to measure the position of a person, but the position of an object must be acquired manually using a tool. To acquire a 3D position of an object, it requires 3D interaction, which is difficult to a general user. GUI(Graphical User Interface) is relatively easy to a general user but it is hard to gather a 3D position. This study proposes the Interactive LOcation Context Authoring Toolkit(ILOCAT), which enables a general user to easily acquire a 3D position of an object in real space using GUI. This paper describes the interaction design and implementation of ILOCAT.
