최근 모바일 기기의 사용이 활발해지고 있고 모바일 기기에서의 입력방식은 터치스크린을 이용한 입력방식이 주로 이용되고 있다. 또한 소셜 네트워크 서비스(SNS)의 사용자 급증의 영향으로 모바일 기기를 이용한 소셜 네트워크 서비스의 사용자 수 역시 급증하고 있는 추세이다. 본 논문에서는 소셜 네트워크 서비스에서 타인에게 사용자의 감정을 더 쉽게 전달 할 수 있도록 사용자에게 스케치 정보를 입력받아 사용자의 감정을 표현하는 한 장의 자연스러운 그림을 생성하고 모바일 환경에서 사용자가 더 쉽게 스케치 정보를 완성할 수 있도록 하는 유저 인터페이스를 제안한다.

The importance of User Interface (UI) in mobile phone has increased as the complexity of use increases due to the new technology adoption. The complexity and load for user interface development has increased accordingly. This paper discusses how to make a structured UI development process based on the mobile phone UI development case. After the review of UI development process and issues arising during the development, four levels of user interface guidelines are proposed such as macro rules, action templates, application rules and interaction cases. The importance of dealing various interaction case is emphasized which is not referred in the present industry UI guidelines. Most of research related to UI development focus on the target product rather than how to make good UI process. Based on the good UI process, good UI of the product can be realized. This proposed process based on UI guidelines will help to step up the UI development of mobile phone industry. Also, this process can be applied to different products or services.

In typical master/slave teleoperation systems, a human operator generally manipulates the master to control the slave through the visual information like camera image. However, the operator may get into trouble due to the limited visual information depending on the camera positions and the delay on the visual information because of low communication bandwidth. To cope with this inherit problem in the camera-based teleoperation system, this paper presents a teleoperation system using a reconstructed graphic model instead of the camera image. The proposed teleoperation system consists of a robot control module, a master module using a force-reflective joystick, and a graphic user interface (GUI) module. The graphic user interface module provides the operator with a 3D model reconstructed using a small set of sensing data received from the remote site. The proposed teleoperation system is evaluated through a peg-in-hole assembly task.

This study presents an application of GIS technologies to construct the graphic user interface for 3-dimensional exhibition of the results obtained by ocean hydrodynamic model. In coastal management studies, GIS provide a receptacle for scattered data from diverse sources and an improvement of the 3D visualization of such data. Within the frame of a GIS a variety of analytical, statistical and modeling tools can be applied to transform data and make them suitable for a given application. A 3D hydrodynamic model was driven by time-dependent external forcing such as tide, wind velocity, temperature, salinity, river discharge, and solar radiation under the open boundary condition. The Jinhae Bay was selected as a case study. Here, we have used GeoMania v2.5 GIS software and its 3D Analyst extension module to visualize hydrodynamic model result that were simulated around the Jinhae Bay.

The assessment of environmental impact on NO$_2$ (or TSP) emitted by vehicles is important for local residents from the point of view of their health and environmental protection. In the course of field investigations, correct concentrations are measured and meteorological data are observed for numerical simulation. To determine background concentration for numerical simulation, annual average concentrations of NO$_2$ (or TSP) are estimated using the Puff-Plume model. If the estimated result affects the environment, it must be considered in the environmental conservation activity. To make the process of a estimation of environmental assessment more easily, this system is developed. Moreover, this system was supplied a Graphic User Interface (GH) for the user who calculated the concentration of air pollution exhausted from the traffic on general roads except special roads such as interchanges and entrances to tunnels. This system can offer not only the numerical result but also a graphic display. Even a beginner who is not a professional programmer can calculate the result easily.

In order to design and develop a ubiquitous game, it is necessary to develop a natural and flexible interface between the real world and the virtual world, based on social and physical context awareness. We design user interface model and the tactile sensing system that performs virtual interaction and collection of the sensor data. It is sensitive so the collected data should be filtered, rearranged and analyzed. This information is quite different from stylus input, keyboard, button or mouse for interaction. We detect kicked 3D force position of a ball, moment of area, moment of inertia and modified ball shape using tactile sensing system and analyzed data. The results demonstrate that the proposed approach is desirable and robust as well as the results can be used realistic actions and reactions considering attack force and to make interesting environments for ubiquitous game.

As music streaming services (MSS) involve various interactions with users during the music consumption process, it is important to understand the user experience and manage the service accordingly. This study developed a user experience model for MSS by theoretically linking the quality characteristics considered important by music service users with the structure of user experience. PLS analysis was then performed using survey data to test the model. As a result, functionality (search, browsing, and personalized recommendation), UI usability, content quality (currentness, sufficiency, relevance), and monetary cost were found to be key experience factors that determine the experience consequence, i.e., user satisfaction. In addition, in a supplementary analysis comparing domestic and global services, differences in user experience were found between the two groups in terms of functionality and content quality. The user experience model of MSS proposed in this study serves as a new foundation for theory-based research in this field and provides meaningful implications for the competitive landscape among music streaming service platforms and for their competitive strategies.

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.

As the world game marcket has been recording weak growth, the development of new gane concept is required to attract the gamer's attention from those who were fed up with the previous game paradigm. Recently, the game which can recognize the player's motions and provide new interaction between the game and user is more popular than ever before. In the games with somesthesia based on Virtual Reality, the sense of the reality is considered the most important factor for drawing immersion from the gamers. In this work, a new type of 3-axis accelerometer based interactive game interface which can effectively recognize the gamer' motion is suggested. Furthermore, various experiments are carried out to verify the effectiveness of the proposed scheme.
