Various interaction techniques have been studied for providing the feeling of touch and improve immersion in augmented reality (AR) environments. Tangible AR interaction exploiting two types (product-type and pointer-type) of simple objects has earned great interest for cost-effective design evaluation of digital handheld products. When the sizes of markers attached to the objects are kept big to obtain better marker recognition, the pointer-type object frequently and significantly occludes the product-type object, which deteriorates natural visualization and level of immersion in an AR environment. In this paper, in order to overcome such problems, we propose tangible AR interaction using fingertip touch combined with small-sized markers. The proposed approach facilitates the use of convex polygons to recover the boundaries of AR markers which are partially occluded. It also properly enlarges the pattern area of each AR marker to reduce the sizes of AR markers without sacrificing the quality of marker detection. We empirically verified the quality of the proposed approach, and applied it in the process of design evaluation of digital products. From experimental results, we found that the approach is comparably accurate enough to be applied to the design evaluation process and tangible enough to provide a pseudo feeling of manipulating virtual products with human hands.

This study has utilized the Quality Function Deployment (QFD) technique in order to plan the tangible (menu) and intangible (service) product of dumpling restaurant. The engineering characteristics of tangible products were classified into product planning, purchase management, production management, and information management based on the production system of foodservice. The engineering characteristics of intangible products were also classified into physical evidence, human interaction, and pre-communication based on the service operation and delivery system. As a result of analyzing the QFD, it was found that the customer hope the hygiene factor and response factor to be improved. It is analyzed that product planning, information management, and production management should be improved first in terms of engineering characteristics considering consumer needs. In the future, by utilizing the systematic product development process that the requirements of tangible and intangible product consumers are converted to the engineering characteristics, the development of competitive product within the market will be possible, and furthermore it is expected to be useful for reducing the unnecessary time and design costs due to failure of product development.

Nowadays personal users create a variety of multi-media contents and share them with others through various devices over the Internet since the concept of user created content (UCC) has been widely accepted as a new paradigm in today's multi-media market, which has broken the boundary of contents providers and consumers. This paradigm shift has also introduced a new business model that makes it possible for them to create their own multi-media contents for commercial purpose. This paper proposes a tangible virtual studio using augmented reality to author multi-media contents easily and intuitively for personal broadcasting and personal content generation. It provides a set of tangible interfaces and devices such as visual markers, cameras, movable and rotatable arms carrying cameras, and miniaturized set. They can offer an easy-to-use interface in an immersive environment and an easy switching mechanism between tangible environment and virtual environment. This paper also discusses how to remove inconsistency between real objects and virtual objects during the AR-enabled visualization with a context-adaptable tracking method. The context-adaptable tracking method not only adjusts the locations of invisible markers by interpolating the locations of existing reference markers, but also removes a jumping effect of movable virtual objects when their references are changed from one marker to another.

자산은 기업의 재무상태와 경영성과산출에 있어서 매우 중요한 요소이다. 사회간접자본인 철도산업은 거대한 유형자산을 보유하고 운영에 막대한 자산관련비용이 발생하는 특징을 가지고 있으며 유동성과 수익성의 제고를 위하여 보다 적극적인 자산관리가 필요하다. 유형자산의 회계처리방법은 2011년부터 국제회계기준(IFRS)을 의무적으로 채택하면서 크게 변경됨으로써 자산관리에 큰 영향을 받게 되었으며 유형자산의 비중이 높은 철도산업에 있어 유형자산의 회계처리기준이 중요의사결정으로 대두되었다. 철도산업에 있어 새로이 채택한 유형자산회계기준의 영향을 분석하여 해결책을 제시하고 원가기획 및 원가관리의 효과적 수단으로 주목을 받고 있는 수명주기원가계산(LCC)를 효과적인 자산관리 수단으로 제시하고자 한다.

본 논문은 제품의 고장모드를 예측하고 제거하는 FMEA를 체감형게임의 안전성 평가척도에 적용함으로써 체감형게임의 사용가능성을 증진시키는 방법에 대한 논문이다. 체감형게임이 제공하는 작동화된 인터랙션이라는 특징 때문에 사용자들은 예상치 못한 사고들을 겪게 되었다. 이에 본 논문은 Wii 사고사례들 중 게임기기와 신체상해부위의 두 가지 분류 내의 위험요인(고장모드)들을 FMEA를 사용해 우선순위를 매겨보았다. 그 결과 게임기기에서는 TV가, 신체상해 부위에서는 손열상 및 타박상이 가장 큰 위험요인으로 나타났다. 이를 바탕으로 FMEA를 활용한 체감형게임 안전성 평가모델에서 가장 우선적으로 고려해야 할 안정성 평가 순위를 제공하고, 상이한 체감형게임 기기들 간의 일관성 있는 평가 가이드라인을 제공할 수 있는 기초를 마련하였다.

In the research of HCI (Human-Computer Interaction), we always use the GUI（graphical user interface） of graphics input devices until we invent TUI (tangible user interface) which is used to control the computer by hand-touching or other subjects. In this study, we investigate and classify several TUI for the most part in business with the theory and concept of Tangible Bits by Hiroshi Ishii & Brygg Ullmer in order to research the development of TUI.

In this paper, we present a tiled display system for tangible meeting. We built our system as a distributed system and use GPU based warping and image blending technique for real-time processing. For efficiency, we update specific area only, where the remote user exist, in real-time and blended it with static panoramic image of remote site.
