디지털방송의 애플리케이션(Xlet)은 시청자와 방송프로그램간의 상호작용에 중요한 역할을 담당한다. 현재 이러한 애플리케이션 UI는 평면이미지로 구성하는 것이 대부분이며 화면상 영역은 2차원으로 제한된다. 본 논문은 이러한 2차원의 평면적인 느낌을 극복하고 3차원이 가진 다양한 이점을 살리기 위한 3차원 UI구현방법을 제시한다. 이를 위해, 본 논문은 가상의 3D System, Virtual Timeline, Animation Model 등을 구성하였다. 3D System이란 UI가 3차원 좌표계를 가지기 위한 환경을 말하며, Timeline과 Animation Model은 제한적인 성능의STB에서 보다 진보된 애니메이션을 UI에 적용하기 위한 기법이다. 이들은 다양한 애플리케이션 제작, 서비스 개발 등에 응용이 가능하다. 디지털방송은 매우 빠른 속도로 발전하고 있으며 새로운 형태의 서비스가 속속 등장하고 있다. 이러한 흐름에 발맞춰 3D UI는 기존의 TV 화면에서 보다 진보된 형태의 사용자 인터페이스의 모습을 보여줄 것이다.

This study is a VR system design designed to evaluate the impact of interaction on user experience analyzed by developer's perspective for the interactive VR fashion show. In the VR fashion show design, we produced an interactive system through the four interactive elements of camera viewpoint, cloth, effects, and sound. The interactive design system is proposed based on three application facto rs in VR space design: speed, range, and mapping. The study focused on the user experience based on format conversion to apply the Unity3D engine using 3D model, animation, 2D UI design, and simulation.

The computer game has a narrative structure, which scenario is proceeded by player's consecutive interactive. The interaction is the core of game plays that is not only storytelling in itself, but also is implemented by interface. The UI of computer game is as a tool for communication between player and game, which has been designed by usability on use. However, is it the necessary for us to get synchronization of feelings about game scenario in terms of a psychological in order to deepen the pleasure that is the game's ultimate goal. Effectively, as a way to lead in this empathy. This study tries to application of storytelling to the UI that occurred player's interactive for the first time. Moreover, presented the result as the UI designs of casual MMORPG.

Since two-way interactive broadcasting service began, remote controls have been fitted with 4 color buttons, which enables interaction and convenience to increase between users and content. Currently, diverse studies on IPTV are in progress. Particularly, as the mobile market rapidly grows, studies on mobile IPTV and on linkage with other media are constantly increasing. However, mobile IPTV has never been studied until now. In that sense, this present study attempted to design a mobile-based IPTV UI that could use a multi-dimensional search method based on consistent criteria for content search. As a result, the proposed IPTV UI is fitted with more usability and functionality for 4 color buttons. The UI designed in this study was compared to the IMDb Android Application, which uses GOMS-KLM. The results showed that the performance process was reduced by three stages, and that the performance time was reduced by more than 17.9%. Therefore, the conclusion can be reached that the proposed UI is effective for a fast search of contents.

Digital TV broadcasting technology is recognized as a very encouraging technological development by koreans because of high-definition, multi-channel and interactive services which would broaden the viewers choice and promote people's prosperity. The technological development of digital TV service is a drastic change for people's convenience and would be a major media of‘e-government’in Korea. Digital TV Program UI will affect to people's esthetic sense and information efficiency. The information search pattern in TV is different from it of computer which has lead interactive media so far This research verifies the reasonable information display method through the usability test based on former related researches. For the case study, Interactive EPG design of SkyLife is selected and reviewed. This research includes the design development of interactive EPG of DVB-MHP.

디지털방송은 애플리케이션(Xlet)을 이용해 보다 진보된 Interactive 방송프로그램을 시청자에게 전달 할 수 있다. Interactive TV에서 애플리케이션은 MHP, OCAP, ACAP등의 표준규약에서 정의된 API를 기반으로 작성되며 MPEG-2 TS를 통해 STB(Set-Top Box)에 전송되어 구동된다. 현재 이러한 애플리케이션은 고정된 이미지를 활용한 형태의 서비스가 주를 이루며 중력, 탄성력과 같이 실제와 유사한 움직임을 표현하거나 활용하는데 있어 미흡한 실정이다. 본 논문은 Interactive TV에서 중요한 역할을 담당하는 애플리케이션(Xlet)을 위해, 현재의 STB에서 가능한 물리기반 Simulator Module을 설계하고 구현하였다. 이는 중력, 탄성력, 단진자운동과 같은 다양한 현상을 모형화(단순화)하고 수식화하여 적용한 것으로서, UI와 Game등에 그 활용도가 높을 것이다.

Smartphones have been widely used for various purposes and stay connected with people at all times. However, the use of such touchscreen devices can be physically restricted depending on users' context where only one hand is available to interact with the device. Even major smartphone manufacturers (e.g., Apple, Samsung) offer one handed mode, they still lack functions in the third-party applications, and the process is also complicated. We propose OverIT, a system that enables users to customize interfaces by adding new buttons on an interactive overlay which can be positioned anywhere on the touchscreen where each button serves the same functionality as an existing one. It is designed to support users to map a certain button event freely and easily to a newly created button by performing a demonstration of a button tap. We expect our system to improve the overall user experience of one-handed interaction with touchscreen devices.

There is little study related to the 3D convergence contents authoring tool for teacher. In this study, we purposed the design of the interactive 3D convergence contents authoring tool for a teacher. To draw the design, firstly, we investigated the authoring environment of teachers and interviewed teachers. Based on this investigations, we proposed the functional requirement and UI/UX(User Interface/User Experience) design of it. And we investigated the level of focusing group satisfication with the UI/UX design. Based on these results, we will implement the authoring tool.

This paper will explain the importance of using interactive prototyping tools in the HCI design process. The Future of HCI education project performed by ACM SIGCHI shows that students recognize that prototyping, especially paper prototyping and interactive prototyping, are both very important. Two widely-used prototyping tools in academy, Balsamiq and Oven, will be compared and rated by students according to their preferences. We choose the Balsamiq as our design tool because Oven can be designed on the web but applications cannot be designed directly on Mac or Windows. The Balsamiq tool will help you understand the task process of UI work and highlight the benefits of digital prototyping to test the execution of expected results in a fast fashion compared to high-level prototyping. We also present the outcome of this work through two case studies. In particular, the smart mirror project with voice recognition function shows the effectiveness of the proposed method as an example.
