디지털 방송의 시작과 함께, TV화면에서 채널이나 프로그램을 직접 검색할 수 있는 EPG(Electronic Program Guide)라는 새로운 방송 서비스가 제공되고 있다. 그러나 아직까지는 시청자 입장을 고려한 EPG의 User Interface에 대한 연구는 미흡한 실정이다. TV는 특정 계층이 아닌 모든 사람이 시청하는 매체이의로 시청자에게 프로그램을 쉽게 찾게 하기 위해서는 단순하고 직관적인 User Interface가 필요하다. 이러한 User Interface를 설계하기 위해서는 많은 채널에서 방송되고 있는 프로그램을 체계적으로 구분학 수 있는 정보구조와 정보구조들을 유연하게 연결시킬 수 있는 Navigation의 설계가 필요하다. 일반적으로 프로그램을 구분하는 방법으로 장르, 시간, 등급, 프로그램의 내용 등과 같은 속성을 이용한다. 하지만 이러한 속성들은 체계적으로 구조화되어 있지 않다. 본 논문에서 제안하는 EPG는 프로그램이 가지는 속성들을 체계적으로 정리해 구조화하고, 이렇게 구조화된 속성들을 시청자들이 쉽게 선택해 원하는 프로그램을 찾을 수 있는 유연한 Navigation을 설계함으로써 기존의 EPG보다 쉽고 빠르게 프로그램을 검색 학 수 있는 User Interface를 제안하고자 한다.

Throughout the history of computer use, the interface metaphor has been employed to make computers easier for humans to use. Even the earliest command line interfaces used metaphor. Metaphors in user interfaces help to make the software accessible to users and allow the users to communicate with the system as well. User interface guidelines for most of the popular operating systems encourage the use of metaphors in interface design. Thus, metaphor in interface design is employed as central element with a long history. Therefore, this paper will suggest substantiating guidelines which are based on conceptual model and Gestaltprinciples for successful metaphor construction with a better user interface.

In this paper, a new text-based method is suggested for the user-system interaction. The use of text-based user interface is mote efficient under situation which don't be introduced the GUI because of the limitation of hardware cost or improvement of system performance. The dialogical method using suggested hierarchical structure is the easier for a convenience of usage and the method in this paper is the more useful as considering knowledgeable background and environment of task for user As a practical example, the method for the proposed text-based user interface construction is applied to Double-Lift Open Shedding Electronic Jacquard.

A home-based rehabilitation system for patients with uncomfortable hands or arms was developed. By using this system, patients can save time and money of going to the hospital. The system's interface is easy to manipulate. In this paper, we discuss a rehabilitation system using video recognition; the focus is on designing a convenient user interface and rehabilitation training methods. The system consists of two screens: one for recording user's information and the other for training. A first-time user inputs his/her information. The system chooses the training method based on the information and records the training process automatically using video recognition. On the training screen, video clips of the training method and help messages are displayed for the user.

The main objective of this research is to find out whether there exist any user interface factors that influence service information management professionals(SIMP)'s business activities on the web. The result of this study shows that there exists a significant level of difference between two groups of office Professionals： SIMP and general office management professionals on user interface factors. We analyzed the past and current research results and focused on four major evaluation categories： (1) web design, (2) structure, (3) navigation, and (4) interaction and identified 26 evaluation items in those categories. The study has been initiated by an intuition that there might be a significant difference in sets of user interface factors that influence SIMP and general office professionals. From the list of Best 100 Web Sites the best 30 information-providing web sites and the best 30 service-providing web sites were carefully chosen by a panel of 10 members for each group. To evaluate 60 web sites, another panel was formed by 30 professionals from each group, and they conducted evaluation in their own work settings. Reliability analysis on user interface factors and T-test to find out any influencing factors on SIMP were performed. As a result of this study, we have recognized that clarity, formation, consciseness, economics, and robustness are the most influencing user interface factors for web designers to concern when they develop web sites for SIMP. The study result can be improved by enhancing reliability of choosing target web sites In investigate and panel members. Also, in the future study it is recommended to investigate influencing factors for office professionals in terms of. age, sex, experience, academic background, etc.

The purpose of this study is to develop the optimal user/librarian interface in information searching. In order to achive the purpose, the 150 unskilled students as subjects have participated in the study. According to the change of the subjects' psychological information states by the access points within the library system, the subjects have been classified into the five types of model: the initial information state, the accepted identification information state, the bibliographic information state, the stack information state, and the location information state. Librarian's searching support is done for 10 minutes at the each access points. To develop the optimal user/librarian interface, the expected values of the models are calculated. The resultants are as follows: 1) The expected value of the initial information states model is 18.94: 2) The expected value of the accepted identification information model is 27.06: 3) The expected value of the bibliographic information state model is 27.06: 4) The expected value of the stack information state model is 22.38: 5) The expected value of the location information state model is 22.38. Those expected values are compared with each other. The model with the lowest expected value is chosen as the optimal user/librarian interface model. In the result, the user's initial information state model of the optimal user/librarian interface in information searching is developed. In order to search the information with the most effect, user must be interfaced with the librarian at his/her own initial information state.

As the computing landscape is shifting to ubiquitous computing environments, there is increasingly growing the demand for a variety of device controls that react to user's implicit activities without excessively drawing user attentions. We developed an EMG-based car interface that enables the physically handicapped to drive a car using their functioning peripheral nerves. Our method extracts electromyogram signals caused by wrist movements from four places in the user's forearm and then infers the user's intent from the signals using multi-layered neural nets. By doing so, it makes it possible for the user to control the operation of car equipments and thus to drive the car. It also allows the user to enter inputs into the embedded computer through a user interface like an instrument LCD panel. We validated the effectiveness of our method through experimental use in a car built with the EMG-based interface.
