This paper describes a novel navigation algorithm using a locomotion interface with two 6-DOF parallel robotic manipulators. The suggested novel navigation system can induce user's real walking and generate realistic visual feedback during navigation, using robotic manipulators. For realistic visual feedback, the virtual environment is designed with three components; 3D object modeler for buildings and terrains, scene manager and communication manager component. The walking velocity of the user is directly translated to VR actions for navigation. Finally, the functions of the RPC interface are utilized for each interaction mode. The suggested navigation system can allow a user to explore into various virtual terrains with real walking and realistic visual feedback.

Typically internal mobile LCD display modules are connected to the mobile product baseband PCB with flexible printed circuit board equipped with board-to-board connector. This solution has a drawback of limiting the product concept work to certain solutions that are based on connector size, location, flexible PCB length, bending, etc. in the display module. Also flexible printed circuit board based solutions are not completely optimized from reliability point of view, causing flex circuit board breakings. For the external displays in the PC or Home entertainment market, the cable solution is too expensive and resource demanding. The wireless solution has obvious advantages over reliability, low cost and flexibility. This paper describes a wireless audio-visual interface solution.

This research investigates a kill probability model for the performance evaluation of guided missile system, and also develops the user interface implementation for the output of the model based on the visual object-oriented programming application. This paper describes in detail the methodology for the kill probability attained by a missile warhead detonating near an airborne target. The major simulation events used in this research are missile guidance homing point, burst points, and kill mechanism(direct kill, blast kill and fragment kill). For the user interface, we also design and implement the visualization system that can show the graphic style of the kill probability attained by the model. This research will bridge the gap between the sophisticated kill probability model and users who want to see the results interactively with visualization, which can benefit many of other military systems. Some examples are shown, but these will be improved to be better with visual simulation which can visualize all the simulation process of the model.

We aimed to see if approach-avoidance visual experience would have different effects in the valence rating of emojis. Previous literature has shown that approach-avoidance tendencies have influences people's emotional perceptions. Up until now, research on emojis have been heavily focused on static emojis, which gives room for exploration whether if movement added on to emoji would elicit different emotional responses. In the study, we examined the impact of approach-avoidance visual experience of emojis via mobile interface, categorized into 4 experimental conditions (positive approach, negative approach, positive avoid, and negative avoid), and conducted semi-structured interviews to identify users' reasonings towards their valence ratings on specific emojis with approach or avoid movements. We found that positive approach emojis were the highest valence rating and preferred by the participants, while there were no differences between negative emoji approach or avoidance. Based on these findings, we conclude that positive emojis could be intensified to be more positive with approach motion, yet for negative emojis, individual differences or contextual differences may arise in its emotional ratings.

This study applies the 'interface' as the concept to interpret the facade design of parking garages. This study investigates the characteristics of interface design in the parking garages to improve design qualities of parking garages as a daily living space as well as a public space in today's city. The facade of parking garage is an interface between the urban streets and the parking space. Three concepts of interface and design in parking garage are defined. The concept of interface is explained as a boundary surface which activates communication and interaction. In facade design of parking garage, three main concepts of interface design are screen, communication and mobility. Through the investigation of the examples, this study summarizes the characteristics of the facade design of parking garage as follow; first, the facade of parking garage is designed as a screen which represents immateriality by specially selected and arranged surface materials. The screen facade is designed as one homogeneous surface as well as an irregular pattern with operable louvers. Second, the facade of parking garage is designed as a communication media to deliver direct information. The representation of natural or artificial characteristics at the local areas is to communicate with the people in the community. Third, the facade of parking garage is represented mobility which a car symbolizes. It emphasizes various movements and visual changes by movements. People can experience the visual changes of the building facade as they walk or drive. The visual changes of the facade are caused by natural elements such as wind and light as well as an optical illusion.

인터페이스 디자인(Interface Design)을 제작하는 디자이너는 그 정보를 사용자 입장에서 쉽고 빠르게 얻을 수 있게하는 기능성과 심미성을 적절히 조합하여 기능성이 강조된 진보적인 인포메이션 디자인(Inforrnation Design)을 하는 것이다. 그러므로 인터페이스 디자인 작업은 디자이너의 입장이 아닌 사용자 입장이어야 하며, 사용자의 'NEED'를 반영하고 충족시키는 정보전달을 최우선 하는 디자인이 되어야 할 것이다. 본 논문은 지금까지 정립되어있지 않은 인터페이스 디자인의 시각적인 화면(Screen Layout) 구성요소 중 필자가 선정한 10가지의 소재(Visual Elements)를, 디자이너의 입장에서 심미성을 치우쳐 시각적인 아름다움을 강조하여 자칫 인터페이스 디자인의 기본되는 기능성을 배제하는 오류를 범하는 상황을 조금이나마 축소할 수 있는 기능성을 찾아보려 한다.

Objective: Research on the transformation of interaction between mobile machines and users through analysis on current gesture interface technology development trend. Background: For smooth interaction between machines and users, interface technology has evolved from "command line" to "mouse", and now "touch" and "gesture recognition" have been researched and being used. In the future, the technology is destined to evolve into "multi-modal", the fusion of the visual and auditory senses and "3D multi-modal", where three dimensional virtual world and brain waves are being used. Method: Within the development of computer interface, which follows the evolution of mobile machines, actively researching gesture interface and related technologies' trend and development will be studied comprehensively. Through investigation based on gesture based information gathering techniques, they will be separated in four categories: sensor, touch, visual, and multi-modal gesture interfaces. Each category will be researched through technology trend and existing actual examples. Through this methods, the transformation of mobile machine and human interaction will be studied. Conclusion: Gesture based interface technology realizes intelligent communication skill on interaction relation ship between existing static machines and users. Thus, this technology is important element technology that will transform the interaction between a man and a machine more dynamic. Application: The result of this study may help to develop gesture interface design currently in use.

본 논문에서는 VIOLA(VIsual Object-oriented Language for Multimedia Applications)이 시각 언어 프레임워크를 제안하다. VIOLA는 웹 응용 프로그램을 자동으로 생성시켜주는 도구이며, 사용자가 정확한 HTML 태그나 CGI 프로그래밍을 모르더라도 자동으로 고수준의 웹 응용 프로그램을 작성할 수 있게 해준다. VIOLA에서는 사용자 접속 설계 부분과 프로그램의 논리 설계 부분 자료흐름 방식에 의해 통합되어 나타난다. 사용자 접속 설계 부분은 직접 조작과 위지윅을 지원하고, 프로그램 논리 설계 부분은 추상화된 아이콘과 사용자 접속과의 연결을 위한 자료흐름 방식을 사용한다. 프로그램 논리는 도구에서 정의된 클래스를 재사용하여 결합함으로써 자동으로 CGI 프로그램으로 생성되어진다. 이러한 방법은 직관적이고 사용하기 쉬워서 초보자라도 쉽고 빠르게 고수준의 웹 응용 프로그램을 생성할 수 있다. 또한 웹 문서의 생성과 저작에 필요한 일련의 기능들이 통합되어 잇다. 생성된 CGI 프로그램은 java로 구현되기 때문에 HTML 문서와 더불어 플랫폼에 독립적이다.

Recently, various devices requiring text input such as mobile phone IPTV, PDA and UMPC are emerging. The frequency of text entry for them is also increasing. This study was focused on the evaluation of Korean text entry interface. Various models to evaluate text entry interfaces have been proposed. Most of models were based on human cognitive process for text input. The cognitive process was divided into two components; visual scanning process and finger movement process. The time spent for visual scanning process was modeled as Hick-Hyman law, while the time for finger movement was determined as Fitts' law. There are three questions on the model-based evaluation of text entry interface. Firstly, are human cognitive processes (visual scanning and finger movement) during the entry of text sequentially occurring as the models. Secondly, is it possible to predict real text input time by previous models. Thirdly, does the human cognitive process for text input vary according to users' text entry speed. There was time gap between the real measured text input time and predicted time. The time gap was larger in the case of participants with high speed to enter text. The reason was found out investigating Eye-Hand Coordination during text input process. Differently from an assumption that visual scan on the keyboard is followed by a finger movement, the experienced group performed both visual scanning and finger movement simultaneously. Arrival Lead Time was investigated to measure the extent of time overlapping between two processes. 'Arrival Lead Time' is the interval between the eye fixation on the target button and the button click. In addition to the arrival lead time, it was revealed that the experienced group uses the less number of fixations during text entry than the novice group. This result will contribute to the improvement of evaluation model for text entry interface.
