A lot of researchers have been investigating interactive portable projection systems such as a mini-projector. In addition, in exhibition halls and museums, there is a trend toward using interactive projection systems to make viewing more exciting and impressive. They can also be applied in the field of art, for example, in creating shadow plays. The key idea of the interactive portable projection systems is to recognize the user's gesture in real-time. In this paper, a vision-based shadow gesture recognition method is proposed for interactive projection systems. The gesture recognition method is based on the screen image obtained by a single web camera. The method separates only the shadow area by combining the binary image with an input image using a learning algorithm that isolates the background from the input image. The region of interest is recognized with labeling the shadow of separated regions, and then hand shadows are isolated using the defect, convex hull, and moment of each region. To distinguish hand gestures, Hu's invariant moment method is used. An optical flow algorithm is used for tracking the fingertip. Using this method, a few interactive applications are developed, which are presented in this paper.

본 논문에서는 유아를 위한 체감형 게임 개발에 필요한 요소로 콘텐츠, 디자인, 음향, 동작인식, 음성인식 기술을 제안하였다. 유아용 체감형 게임은 유아의 감성에 맞춘 교육적 요구가 반영된 콘텐츠와 밝고 친근감 있으면서 사용이 편리한 디자인 요소들이 반영되어야 하고 유아가 친숙하고도 쉽게 게임을 할 수 있게 유도할 수 있는 배경음악과 설명 대사가 사용되는 것이 좋다. 만약 동작 인식과 음성인식 시스템을 유아용 체감형 게임에 사용할 경우 게임 사용자의 연령에 맞는 동작 데이터와 음성 데이터를 사용해 인식률을 높여야 한다. 특히, 본 논문에서는 피부색과 유아 신체 모델을 사용하여 유아의 얼굴과 손을 인식한 후 그 위치를 고려하여 유아의 동작을 인식하였고 유아의 음성 데이터를 수집해 신경망을 이용한 음성인식 기술을 게임에 적용해 신체 놀이 중심 활동의 줄넘기 게임인 '신나게 폴짝'을 개발하였다.

제품을 디자인함에 있어 정확하고, 신속한 소비자 욕구에 대한 조사는 디자이너의 키치 못지 않게 제품의 성패를 좌우하는 주요한 요소이다. 특히, 각종 매체의 발달이 가져온 정보경제시대의 소비자 욕구변화나, 소비시장의 변화양상은 급속히 그 주기를 좁혀가고 있어 수집된 시장정보의 신속한 제품화는 그 어느때보다 더 절실하게 요구되어지고 있다.(중략)

절차적(procedural) 텍스쳐는 다양한 해상도로 텍스쳐 공간을 표현할 수 있으며, 매우 적은 저장 공간을 사용하는 장점을 가지고 있다. 그러나 절차적 표현을 위한 암시적(implicit) 방법을 이해하기 어렵고 프로그래밍에 익숙하지 않은 일반 사용자가 다루기 힘들다. 본 논문에서는 사용자의 직관적인 디자인작업을 통해 절차적 패턴을 자동으로 생성하는 인터랙티브 시스템이 제안된다. 전체 디자인 과정은 다중레이어(layer)를 기반으로 하며 데이타, 연산 및 출력 노드 등으로 구성된 그래프 구조로 표현된다. 제안된 시스템은 일반 사용자에게 유연한 인터페이스를 제공하여 프로그래밍 작업 없이 절차적 텍스쳐 쉐이더를 자동으로 생성하도록 한다. 시뮬레이션 결과로부터 제안된 방법이 다양한 패턴을 효과적으로 제작할 수 있음을 확인하였다.

To efficiently design safety-critical systems such as nuclear power plants, with the requirement of high reliability, methodologies allowing for rigorous interactions between the synthesis and analysis processes have been proposed. This paper attempts to develop a reliability-centered design framework through an interactive process between Axiomatic Design (AD) and Fault Tree Analysis (FTA). Integrating AD and FTA into a single framework appears to be a viable solution, as they compliment each other with their unique advantages. AD provides a systematic synthesis tool while FTA is commonly used as a safety analysis tool. These methodologies build a design process that is less subjective, and they enable designers to develop insights that lead to solutions with improved reliability. Due to the nature of the two methodologies, the information involved in each process is complementary: a success tree versus a fault tree. Thus, at each step a system using AD is synthesized, and its reliability is then quantified using the FT derived from the AD synthesis process. The converted FT provides an opportunity to examine the completeness of the outcome from the synthesis process. This study presents an example of the design of a Containment Heat Removal System (CHRS). A case study illustrates the process of designing the CHRS with an interactive design framework focusing on the conversion of the AD process to FTA.

This study was conducted to develop and apply a computer-based multimedia nutrition education program for preschoolers based on the Dick and Carey model of instructional design. The Dick and Carey model included 4 phases: analysis, design, development, and evaluation. The program's instructional goals, objectives, assessment instruments, content, examples, and practice questions with feedback were written in the design phase. To be familiar with the 5 food groups, 'Nutrition exploration' were programmed using Hyperstudio. 'Nutrition exploration' was designed as a five-session, interactive multimedia game, with each session taking about 5 minutes to complete. Nineteen preschoolers, aged 6, volunteered to participate formative evaluation. The effectiveness of the program was examined using a pre-post test design. Participants were recruited by personal contact at the individual preschool education center. The application was carried out during 4 weeks. The results showed that intervention participants significantly increased knowledge between pre-test and post-test. The results support using IMM (interactive multimedia) to disseminate nutrition education to the target population. This research provides the basis for continuing development of computer-based nutrition education materials.

The purpose of this study is to evaluate visual arts in interactive technology in art museum applications and to analyze the impact relationship between interactive technology and the five senses. This study was conducted to survey respondents who had used art museum applications. The results are as follows. First, this study evaluates the differences in perception of art museum applications according to the general characteristics of the respondents. They show that there are differences in gender, marital status, age, and social income. Second, this study identifies the impact of five senses and synesthesia on interaction design among emotional design elements. They reveal that visual, auditory, tactile components, and synesthesia have significant effects on interactive design. This study reveals that emotional design elements of art museum applications affect interaction design. Also, it suggests that research on interaction design reflecting five senses is continuously needed to improve audience satisfaction and revitalize art museum applications.

In allowing visitors to manipulate objects or models with their hands, science museums can become informal education institutions. However, little research has been conducted analyzing the specific interactions of visitors at museums and the effects that specific characteristics of interactive exhibit have on visitors. This research classified exhibits according to the three characteristics: the presentation of concepts, interaction with exhibits and concept levels. Further, relationships among engagement behaviors, visitors'attraction to exhibits, and the holding power of exhibits were analyzed. Using the three characteristics, 55 exhibits were classified into five styles. The results suggest that intriguing content and novel interfaces, maximizing information on science and technology, should be developed for the educational purpose of encouraging visitors to engage in active learning with interactive exhibits. The results of this study provide useful data that planners, designers, and instructors of science museums can use to maximize visitors' participatory learning and interactions.
