When the design profession started, design targets were mainly static hardware centered products. Due to the development of network and digital technologies, new products with dynamic and software-hardware hybrid interactive characteristics have become one of the main design targets. To accomplish the new projects, designers are required to learn new methods, tools and theories in addition to the traditional design expertise of visual language. One of the most important tools for the change is effective and rapid prototyping. There have been few researches on educational framework for interactive product or system prototyping to date. This paper presents a new model of educational contents and methods for interactive digital product prototyping, and it's application in a design curricula. The new course contents, integrated with related topics such as physical computing and tangible user interface, include microprocessor programming, digital analogue input and output, multimedia authoring and programming language, sensors, communication with other external devices, computer vision, and movement control using motors. The final project of the course was accomplished by integrating all the exercises. Our educational experience showed that design students with little engineering background could learn various interactive digital technologies and its' implementation method in one semester course. At the end of the course, most of the students were able to construct prototypes that illustrate interactive digital product concepts. It was found that training for logical and analytical thinking is necessary in design education. The paper highlights the emerging contents in design education to cope with the new design paradigm. It also suggests an alterative to reflect the new requirements focused on interactive product or system design projects. The tools and methods suggested can also be beneficial to students, educators, and designers working in digital industries.

In spite of advantage by using BIM as quantity take-off, schedule control and clash check, absence of guidelines is a barrier to applying BIM to road domain. In this research, domestic and overseas cases of BIM guideline are analyzed in order to develop the road BIM deliverable submission system. The analysis is classified 5 topics which are BIM submit product list, submit files format, availability of existing 2D based products, BIM authoring tools and submit process. As a result, It needs a lot of effort to standardize BIM delivery system for road domain because BIM submit product list and BIM authoring tools are changable depending on BIM use cases. However, submit files format and submit process are common part to suggest guidelines of road BIM delivery system. It requires to combine BIM and 2D products for road BIM delivery system because delivery products are not exactly alternative 2D based delivery products for the present. The authors expect this research to use as basic data for development of the BIM deliverable submission system in road domain.

This research paper is applying Writing Supporting System on the previous research study about writing tool data model on interactive storytelling about family Story. Family story writing supporting system enables users to create text, images, videos and digital contents based on experimental knowledge collected from the first and second generations. The paper about studies on writing tool system on family story, aims to create documentary based high quality contents about each family members and family history. At the same time, overcome generation gaps and the lack of creation infrastructures. Throughout this process, the author will contribute to the expansion of creation devices which can be applied in other researches and writing tools.

In order to improve the productivity in the civil engineering field, efforts to apply BIM have been continuing, however, research on information modeling of tunnel structures considering alignment is insufficient. In this study, we proposed the method of building tunnel models reflecting curved alignment by transferring point data to BIM Authoring Tools(BAT) through discretization of alignment in Alignment-centered Modeling Tools(AMT). IFC data schema was derived to consider the physical and spatial elements of tunnel structures and alignment and IFC-based information management for tunnel alignment, tunnel structures and ground conditions was possible by referring to the extended data schema and including meanings in IFC property sets. The ratings for ground condition in Rock Mass Rating(RMR) and Q-system was automatically derived by using generated information model according to the proposed method.

This paper is to suggest how to apply smartphone application making for literature class as a learning tool. New specialists in literature are not satisfied with the traditional learning methods for the acquisition of theoretical knowledge any more. They try to learn the making process of smartphone application using app writing tools to meet their attention and needs. As a result, they can experience "deterritoriatization" of their major. Such a new learning method not only makes the learners build up their literary knowledge, but also plays a part to meet their needs to make it reality as a practical method that satisfies their learning needs. On this basis, there can be a possibility for literature to be the important resource of the contents development for mobile application.

The existing tutoring estimation systems using the authoring tools or HTML forms on the Web environment don't have been improved inconvenient factors of uni-directional interactive systems. In this paper, we design and implement the interactive tutoring estimation system which is conveniently considered to user on the internet environment. The proposed system is divided into teacher and student modules, which have the functions of the new problem insertion and deletion in database, regular examination marking for the former and lecture/test selection, scoring look, etc for the letter. The environment of server system in this thesis is implemented using the IDC file and SQL database for internet access based on Windows NT, client systems are composed to Windows 95 environment based on Explorer or Netscape to access for interactive tutoring systems.

In this paper, we implemented a web-based 3D virtual pottery gallery Using VR authoring tools. With this system, we expect to cause learning motives and Provide more realistic and interactive learning space. Out system was implemented by making panorama images and 3D object modules using Photo Vista. Object Modeler and Reality Studio. Users can connect to this web site(http://artstory.x-y.net), rotate a pottery panoramically, and zoom it in or out. We designed this virtual gallery can have beneficial influence on students' aesthetic aspects through realistic work appreciations in their art education processes.

3D 입체영상 변환 기술은 콘텐츠 확보의 측면에서 그 중요성이 대두되고 있다. 하지만 입체변환 기술은 매 프레임마다 모두 수작업을 거치기 때문에 다수의 인력과 오랜 작업 시간이 필요하여 생산성 문제가 발생하고 있다. 그 중 깊이영상의 외곽선을 벡터 곡선으로 그리는 작업이 수작업을 통해 이루어지고 있으며 오랜 작업시간이 걸리게 한다. 본 논문에서는 기존의 입체영상 변환 과정의 자동화율을 높이기 위한 깊이영상 양자화 및 베지어 곡선 생성 방법을 제안한다. 연속적인 깊이값을 갖는 깊이영상을 입력으로 받아 선형 또는 비선형 기반의 양자화 방법을 이용하여 깊이영상을 양자화 한다. 이 때 경계부분에 발생하는 페더를 제거하여 양자화 깊이영상의 경계를 보정한다. 양자화 깊이영상에서 같은 깊이를 잇는 등심선을 생성하고 방향 변화가 큰 지점인 굴곡점들을 추출하여 등심선을 다수의 곡선으로 구분한다. 각 곡선의 양 끝의 굴곡점과 그 사이의 중간점을 이용하여 3차 베지어 곡선의 제어 포인트를 계산한다. 같은 수행 단계를 모든 등심선에 적용하여 사용자가 미세보정하기 쉬운 3차 베지어 곡선들을 생성한다. 실험 결과를 통해 제안하는 기법의 우수성을 확인하였다.

Although Industry Foundation Classes (IFC) provide standards for exchanging Building Information Modeling (BIM) data, authoring tools still require manual mapping between BIM entities and IFC classes. This leads to errors and omissions, which results in corrupted data exchanges that are unreliable and thus compromise the validity of IFC. This research explored precedent work by Krijnen and Tamke, who suggested ways to automate the mapping of IFC classes using a machine learning technique, namely anomaly detection. The technique incorporates geometric features of individual components to find outliers among entities in identical IFC classes. This research primarily focused on applying this approach on two architectural BIM models and determining its feasibility as well as limitations. Results indicated that the approach, while effective, misclassified outliers when an IFC class had several dissimilar entities. Another issue was the lack of entities for some specific IFC classes that prohibited the anomaly detection from comparing differences. Future research to improve these issues include the addition of geometric features, using novelty detection and the inclusion of a probabilistic graph model, to improve classification accuracy.
