There is a lack of user centered design methods that support effective collaboration between designers and end-users for designing hardware and software integrated digital products. This paper presents the application of Collaborative Design and a new collaborative design prototyping tool for interactive digital product design projects. The tool consists of STCtools(State Transition Chart tools) software, hardware modeling materials, and physical interface toolkits for integrating software and hardware. STCtools allow users to create and edit States, to compose Events describing transitions between States, and to run intermediate or final results of STC. Using the hardware modeling materials and the physical interface toolkit, designers and end-users can collaborately examine the hardware and software integrated concepts in an early stage of the design process. Three collaborative design workshops of designing a portable digital guide for a theme park were accomplished to examine the feasibility of the tool. The results suggested that the tool supported iterative concept development and interactions between designers and end users. Although several user interface problems of STCtools were identified, the participants gave positive feedback on the role of the tool in collaborative concept generation and deployment. It is expected that the results of this study contribute not only to the collaboration between designers and end users, but also to the collaboration between designers, and between designers and other professionals.

This study aims to validate a web-based neuropsychological testing tool developed by Kwak(2007) and to suggest solutions to potential problems that can deteriorate its validity. When it targets a wider range of subjects, a web-based neuropsychological testing tool is challenged by high drop-out rates, lack of motivation, lack of interactivity with the experimenter, fear of computer, etc. As a possible solution to these threats, this study aims to redesign the user interface of a web-based attention testing tool through three phases of study. In Study 1, an extensive analysis of Kwak's(2007) attention testing tool was conducted to identify potential usability problems. The Heuristic Walkthrough(HW) method was used by three usability experts to review various design features. As a result, many problems were found throughout the tool. The findings concluded that the design of instructions, user information survey forms, task screen, results screen, etc. did not conform to the needs of users and their tasks. In Study 2, 11 guidelines for the design of web-based attention testing tools were established based on the findings from Study 1. The guidelines were used to optimize the design and organization of the tool so that it fits to the user and task needs. The resulting new design alternative was then implemented as a working prototype using the JAVA programming language. In Study 3, a comparative study was conducted to demonstrate the excellence of the new design of attention testing tool(named graphic style tool) over the existing design(named text style tool). A total of 60 subjects participated in user testing sessions where their error frequency, error patterns, and subjective satisfaction were measured through performance observation and questionnaires. Through the task performance measurement, a number of user errors in various types were observed in the existing text style tool. The questionnaire results were also in support of the new graphic style tool, users rated the new graphic style tool higher than the existing text style tool in terms of overall satisfaction, screen design, terms and system information, ease of learning, and system performance.

This Paper provides perceptual metrics for video quality based on properties of human visual system, and audio quality based on human audition. All metrics work without reference signals, allowing non-intrusive, in-service measurements. A simple and easy-to-learn user interface displays the metrics and saves them in popular file formats like CSV. In this paper, proposed method was able to various and corrective measurement for the multimedia service video quality. As that it was able to application to set up service guide line and the methode of measurement and system for the set up standardization of the high quality video service.

제품의 사용자 인터페이스를 개발하기 위해서는 해당 제품의 사용 행태를 정확하게 파악하는 것이 핵심적이다. 사용자 행태에 관한 정보를 수집하는 방법으로는 설문이나 개별/집단 면접 등이 흔히 사용되고 있으나, 이는 사용자들의 기억에 의존하는 간접적인 방법이기 때문에 그 정확성을 보장할 수 없다는 것이 단점으로 지적된다. 이 연구에서는 사용자 조작 로그(Log)를 기록, 수집하는 방법을 활용하여 가전 제품의 사용 행태에 대한 정보를 직접적으로 파악하였고 그 결과를 바탕으로 사용자 중심 인터페이스 디자인을 개발하고자 하였다. 디지털TV실사용자 가구들을 조사 대상으로 선발한 후 해당 가정의 실제 사용 환경에서 약 1개월간 사용 로그를 기록하였다. 로그 수집과 함께 면접 설문도 실시하였다. 수집된 로그를 통계적으로 분석하여 제품의 주요 기능별 사용 빈도와 패턴을 추출해 낼 수 있었다. 이 결과를 면접에서 대상자들이 응답한 내용과 비교하여 간접 조사 방법의 정확도를 검증해 보았다. 로그 분석 결과에서 도출된 사용 행태 데이터를 근거로 사용자 맞춤 인터페이스 기능을 제안하였다. 또한 각 가구별 결과를 2차 분석하여, 사용 행태 데이터를 기반으로 한 사용자 세분화(Segmentation)를 하였고 각 세그먼트(Segment)별 주요 특징을 도출해 낼 수 있었다. 이러한 여러 분석 결과는 가전 제품의 사용자 중심 인터페이스 개발에 사용 Log분석이 활용될 다양한 가능성과 유용성을 보여주었다.

Manufacturing companies are implementing a so-called customer-centered supply chain management to have a competitive advantage. In these efforts, collaboration not only within a company but also with suppliers, partners and customers is emphasized. The fast delivery, reducing the total lead-time from development to delivery, is pursued more than ever, though the quality and cost are still importantly regarded. Die manufacturing companies are not exception from these trends, because a die is a necessary tool for almost manufacturing industries. The planning and scheduling system plays an important role in supply chain management. In this study, we address a scheduling problem of a die manufacturing company. The problem is very complex due to many reasons including the uncertainty in environment and the complexity of constraints. Considering the importance of due-date satisfaction and human planners' roles, we designed the solution algorithm and the user interface respectively. In the implementation phase, modeling constructs and basic solution algorithms of ILOG solver and ILOG scheduler are used. In the paper, the problem and the algorithm are described with ILOG constructs, and the experience of use is also addressed.
