This study investigated through eye tracking what gaze path the audience searches through portal sites (Naver, Daum, Zoom, and Nate). As a result of the layout analysis according to the gaze path of the search engine, the four main pages, which can be called to be the gateway to information search, appeared in the form of a Z-shaped layout. The news and search pages of each site use an F-shape, which means that when people's eyes move from top to right in an F-shape, they read while moving their eyes from left to right(LTR), which sequentially moves to the bottom. As a result of analyzing through the heat map, gaze plot, and cluster, which are the visual analysis indicators of eye tracking, the concentration of eyes on the photo and head copy was found the most in the heat map, and it can be said to be of high interest in the information. The flow of gaze flows downward from the top left to the right, and it can be seen that the cluster is most concentrated at the top of the portal site. The website designer should focus on improving the accessibility and readability of the information desired by the user in the layout design, and periodic interface changes are required by investigating and analyzing the tendencies and behavioral patterns of the main users.

As studies on ubiquitous computing are actively conducted, desire for various services, including image transmission storage, search and remote monitoring. has been expanding into mobile environment as well as to PCs. while CCTV (closed circuit TV) and un DVR (Digital video Recording) are used in places where security service such as intrusion detection system is required, these are high-end equipment. So it is not easy for ordinary users or household and small-sized companies to use them. Besides, they are difficult to be carried and camera solution for mobile device does not support high-quality function and provides low-definition of QVGA for picture quality. Therefore, in this study, design and implementation of embedded system of high-definition image transmission for ubiquitous mobile device which is not inferior to PC or DVR are described. To this end, usage of dedicated CPU for mobile device and design and implementation of MPEG-4 H/W CODEC also are examined. The implemented system showed excellent performance in mobile environment, in terms of speed, picture quality.

In this paper, an USB-OTG (Uiversal Serial Bus On-the-go) interface module was designed with the iris information for personal identification. The image recognition algorithm which was searching face and iris areas, was proposed with pixel differences from eye blinking after several facial images were captured and then detected without any activities like as pressing the button of smart phone. The region of pupil and iris could be fast involved with the proper iris area segmentation from the pixel value calculation of frame difference among the images which were detected with two adjacent open-eye and close-eye pictures. This proposed iris recognition could be fast processed with the proper grid size of the eye region, and designed with the frame difference between the adjacent images from the USB-OTG interface with this camera module with the restrict of searching area in face and iris location. As a result, the detection time of iris location can be reduced, and this module can be expected with eliminating the standby time of eye-open.

Recently, automobile black boxes have evolved to support functionality to transfer videos stored in them into mobile phones via wireless network, from which the videos can be utilized for various purposes. This paper presents a method for automation of traffic violation reports using the automobile black boxes. When a traffic violation is captured by a black box, the proposed method helps a user to transfer the video capturing it into a mobile phone through a simple UI operation. With the video, an HTTP request to report the violation is automatically generated from the mobile phone, and then is transferred to a cyber-report center. We present a prototype system that implements the proposed method, and discuss several issues necessary to apply the method to real-world applications.

The use of gestures provides an attractive alternate to cumbersome interface devices for human-computer interaction. This has motivated a very active research area concerned with computer vision-based analysis and interpretation of hand gestures. The most important issues in gesture recognition are the simplification of algorithm and the reduction of processing time. The mathematical morphology based on geometrical set theory is best used to perform the processing. A key idea of proposed algorithm in this paper is to apply morphological shape decomposition. The primitive elements extracted to a hand gesture include in very important information on the directivity of the hand gestures. Based on this characteristic, we proposed the morphological gesture recognition algorithm using feature vectors calculated to lines connecting the center points of a main-primitive element and sub-primitive elements. Through the experiment, we demonstrated the efficiency of proposed algorithm. Coupling natural interactions such as hand gesture with an appropriately designed interface is a valuable and powerful component in the building of TV switch navigating and video contents browsing system.

In this paper, we suggest a fish drug domain ontology to show an associated information and hierarchy together through concept-relation and inference mechanism instead of keyword matching. First, we investigate competency questions from workers of fishery industry and then we derive concepts and terminologies. Next, we present a process of fish drug ontology modelling using Protege-OWL editor, which is an extension of Protege that supports the Web Ontology Language(OWL). Last, we suggest the user interface of semantic web-based fish drug information system to search easily associated informations of fish drug using this ontology. It is to provide an effective search method that fish disease manager, fish farmer, and students majoring in fisheries can confirm details of diseases, fish, and drug evaluations associated with fish drug within one screen without moving to another position.

In order to treat a disease, it is necessary to take the medication on time, but many people often violate or forget the time they take the medicine. Applications are emerging to solve these problems using information technology. However, for existing applications, it is difficult to use because it provides only a notification functions, user interface is inconvenient, and photo registration of the medication is impossible. To solve these problems, the study developed a smart medicine management application that allows users to set up their taking routines, check if they are taking them, search hospitals and pharmacies, and attach images of medicines they are taking. Through this appliaction, it is possible to reduce the frequency of forgetting the time taken and to take accurate medication by checking the actual image. It also supports the setting of a taking routine to support multiple medications with different taking cycles. It can also provide information about hospital and pharmacies close to their current location to increase access to hospital and pharmacies.

Newsweek 가 2007 년을 '위젯의 해'라고 선언할 정도로 IT산업에서 위젯에 대한 관심이 커져가고 있다. 위젯은 인터넷으로부터 정보를 전달 받아 화면에 표시하는 작은 그래픽 사용자 인터페이스 도구의 일종을 뜻한다. 위젯은 웹 사이트와 연동하여 제 기능을 다할 뿐 아니라 데스크톱, 모바일, 심지어 TV로까지 연동될 채비까지 갖추어 가고 있다. 그러나 현재 TV 환경에서는 TV용 위젯 그래픽 가이드라인이 없는 실정이다. 본 연구의 목적은 TV 시청 환경에 적합한 위젯 가이드라인을 제안함에 있다. TV와 PC의 사용 환경은 서로 다르며 크게 세 가지 측면으로 볼 수 있다. 첫째는 목적적 측면이다. PC는 주로 작업, 검색의 목적을 가지고 있는 반면, TV는 즐기고, 쉬기 위한 목적을 가지고 있다. 둘째는 조작적 측면이다. PC는 키보드, 마우스와 같은 다양한 입력 도구를 사용하여 문자와 위치 등을 쉽게 입력하고 다양한 조작을 할 수 있는 반면, TV는 리모컨으로 제한적인 조작을 한다. 셋째는 시청 환경적 측면이다. TV의 시청거리는 PC나 모바일 보다 멀다. 그리고 보편적으로 가족이 공유하는 미디어라는 점을 알 수 있다. 본 연구를 위하여 세 가지 선행연구를 종합하였다. 첫째, 위젯의 정의와 유형에 대해서 연구하였다. 둘째, TV와 PC환경의 차이를 연구하였다. 셋째, 위젯과 TV의 가이드라인을 분석하였다. 이와 같은 선행연구를 종합하여 TV 환경에 적합한 위젯 디자인 가이드라인을 도출하였다. 연구자는 가이드라인을 콘텐츠, 그래픽, 인터랙션 세 부분으로 나누어 각각에 대한 가이드라인을 제안한다. 또한 연구자가 제안하는 가이드라인의 적합성을 검증하기 위하여 이 가이드라인에 토대로 한 TV 용 위젯을 제안한다. 연구의 범위는 국내의 40 인치 HDTV를 중심으로 제한한다. PC 에서처럼 TV 에서 위젯이 정착하기 까지 많은 시행착오가 있을 것이라 예상된다. 본 연구가 TV 환경에 적합한 위젯에 관한 연구의 시작이 되기를 기대한다.

In this paper, We explain the development of helicopter avation information system which provides the current location and other pre-saved informations in order to guarantee the safe aviation. The system we developed has the functions such as displaying digital map data and current location, route planning, displaying the rate of deviation, calculating and displaying the cross sectional view through the route and providing a real-time speed, heading and other informations. In this system, we use GPS to get the current location, made the 1:250,000 digital map to display the current location and made the cross sectional view from the DEM(Digital Elevation Mode)) data to help safe aviation. This system provides many kinds of route setting methods by using UTM coordinates, Lati. Longi, coordinates, database of heliport location, scanned map, etc., and displaying the heading and distance. Moreover, it also has a characteristic of providing a consistent user interface.
