In this paper, we present the Touch Text exTractor (Touch TT), an interactive text segmentation tool for the extraction of scene text from camera-based images. Touch TT provides a natural interface for a user to simply indicate the location of text regions with a simple touchline. Touch TT then automatically estimates the text color and roughly locates the text regions. By inferring text characteristics from the estimated text color and text region, Touch TT can extract text components. Touch TT can also handle partially drawn lines which cover only a small section of text area. The proposed system achieves reasonable accuracy for text extraction from moderately difficult examples from the ICDAR 2003 database and our own database.

We describe a scheme for developing character-based interface within the context of an agent-based tutoring system in the Web environment. The ideas in this paper stem from original work representing aspects of human emotion in tutoring computer models, where may provide mote natural ways for students to communicate with digital learning materials. The proposed system model is a set of software services that enable developers to incorporate interactive animated characters into their Web pages designed for on-line lectures. The prototypical application is developed and shown for validating the applicability and the effectiveness of this model in real tutoring settings.

선석배정문제는 항만운영 및 관리의 첫단계이며, 각 항만의 지리적, 자연적 특성에 따라 매우 독특하면서 복잡한 성향을 띠고 있다. 특히, 인천항은 그 지리적 특성상 갑문이라는 특수한 시스템과 많은 종류의 화물을 취급하기 때문에 만성적인 체선·체화 현상을 보이고 있으며 많은 물류비의 상승 등 경쟁력을 상실하고 있는 실정이다. 본 연구에서는 인천항의 갑문이용과 선석의 배정문제에 있어서 실제 인천항을 운영하는 전문가 집단의 지식을 규칙화하고, 실제자료를 토대로 갑문의 영향을 분석하여 보다 효율적으로 운영할 수 있는 시스템과 예기치 못한 상황에 대한 대처를 원활히 할 수 있는 선석운영 의사결정지원시스템을 구축하였다. 특히 본 연구에서는 기존 연구에서 고려하지 못한 갑문을 중심으로 교차제한사항과 선석운영의 효율을 높일 수 있는 이안을 예상한 입항선박을 고려하였으며, 더 나아가 사용자로 하여금 쉽고 빠르게 선석을 운용할 수 있도록 개선된 그래픽 사용자 인터페이스(Graphic user Interface)를 갖는 대화식 접근법(User interactive approach)체제의 실시간 선석운영 의사결정지원시스템을 개발하였다.

We present a use. interface(UI) simulator for developing a mobile phone. This simulator consists of 3 major modules: Graphic Tool Editor, User Interface Software(UI), and Network Command Processor(NCP). The Graphic Tool Editor can design a virtual mobile terminal. The NCP sends a command to the phone and then receives its status from the phone after completion of the command. We can add or modify lots of features easily to the phone using the UI module. These modules can interact each other by sharing the common area in the memory. By doing so, these modules can exchange their status and data to operate in real-time. We have designed and tested a virtual prototyping phone for the LGP 3200 manufactured by LGIC by using the simulator. Through a series of experiment, we have believed that our virtual prototyping interactive simulator can do shorten its development and testing cycle by applying it in the early design phase.

This paper describes the design of a high-level synthesis system. ISyn: Interface Synthesis System for ISPS-A. which generates hardware satisfying timing constraints. The original version of ISPS is extended to be used for the description/capture of interface operations and timing constraints in the ISPS-A. To generate the schedule satisfying interface constraints the scheduling process is divided into two steps:pre-scheduling and post-scheduling. ISyn allocates hardware modules with I/O ports by the clique partitioning algorithm. Experimental results show that ISyn is capable of synthesizing hardware modules effectively for internal and/or interactive operations.

Most measuring devices are equipped with RS232 interface or GPIB interface for communicating with computers. If the measuring devices can be accessed by a server computer, the valuable information from the devices can be effectively shared with other computer via internet. VRML is a web based technology for specifying and delivering three-dimensional interactive visualizations over the internet through a web browser. This paper proposes a remote 3-dimensional monitoring system for digital multimeter equipped with RS232 interface by utilizing VRML.

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.

This study suggests a model of experimental visual artworks with interactive art forms in which 2-D paintings are transformed to interactive 3-D animation works. Multimedia programming was employed to evolve objective still paintings to the animation of computer 3-D images with respect to visual ideas derived from visual components in the still painting and to response to the reactions users. The format and technique of the art works are based upon the contents developed by the author and the research materials are selected from the surrealistic paintings of tile world-famous Belgian painter, Rene Magritte. In the present paper, following topics are discussed in detail: a study of various visual cases occurring in transforming still paintings to animation works containing interactive components; a study of 3-D imaging and image processing techniques to transform 2-D paintings to 3-D images; animation techniques for interaction and overall structuring techniques; multimedia programming and user interface.

The amount of web traffic has increased as a result of the rapid growth of the use of web-based applications. In order to obtain valuable information from web logs, we need to develop systems that can support interactive, flexible, and efficient ways to analyze and handle large amounts of data. In this paper, we present CERES, a log-based, interactive web analytics system for backbone networks. Since CERES focuses on analyzing web log records generated from backbone networks, it is possible to perform a web analysis from the perspective of a network. CERES is designed for deployment in a server cluster using the Hadoop Distributed File System (HDFS) as the underlying storage. We transform and store web log records from backbone networks into relations and then allow users to use a SQL-like language to analyze web log records in a flexible and interactive manner. In particular, we use the data cube technique to enable the efficient statistical analysis of web log. The system provides users a web-based, multi-modal user interface.

The input for computer interaction design is very limited for the users to control the interface by only using keyboard and mouse. However, using the basic electrical engineering, the input design can be different from the existing method. Interactive art using computer technology is recently emersed, which is completed by people's participation. The electric signal transmitted in digital and analogue type from the interface controled by people to the computer can be used in multimedia interaction design. The electric circuit design will be necessary to transmit very safe electric signal from the interface. Electric switch, sensor, and camera technologies can be applied to input interface design, which would be alternative physical interaction without computer keyboard and mouse. This type of interaction design using human's body language and gesture would convey the richness of humanity.
