Tangible Space Initiative (TSI) is a new framework that can provide a more natural and intuitive Human Computer Interface for users. This is composed of three cooperative components: a Tangible Interface, Responsive Cyber Space, and Tangible Agent. In this paper we present a Tangible Tele-Meeting system in TSI, which allows people to communicate with each other without any spatial limitation. In addition, we introduce a method for registering a Tangible Avatar with a Tangible Agent. The suggested method is based on relative pose estimation between the user and the Tangible Agent. Experimental results show that the user can experience an interaction environment that is more natural and intelligent than that provided by conventional tele-meeting systems.

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.

This paper deals with a tangible interface system that introduces robot as remote avatar. It is focused on a new method which makes a robot imitate human arm motions captured from a remote space. Our method is functionally divided into two parts: capturing human motion and adapting it to robot. In the capturing part, we especially propose a modified potential function of metaballs for the real-time performance and high accuracy. In the adapting part, we suggest a geometric scaling method for solving the structural difference between a human and a robot. With our method, we have implemented a tangible interface and showed its speed and accuracy test.

본 논문에서는 거실에서의 가족이 즐길 수 있는 IPTV 게임에 활용될 수 있으며, 유년기 자녀들의 게임 중독을 막을 수 있는 텐저블 전자 주사위 인터페이스를 제안한다. 제안된 텐저블 전자 주사위 인터페이스는 실제 주사위와 가능한 유사하게 설계되어 직접적이고 직관적인 조작으로 사용자들이 사용할 수 있도록 하였다. 제안된 인터페이스는 외부 장치를 필요로 하지 않는 자립식(self-contained) 장치이다. 실험을 통해 제안된 주사위 인터페이스가 PC나 IPTV 환경에서 동작하는 게임에 효과적으로 적용될 수 있음을 확인할 수 있다. 앞으로 이 장치를 현재 개발중인 IPTV 게임 등에 적용하여 실용성을 검증할 예정이다.

In this paper, we present an efficient tiled stereo display system for tangible meeting. For tangible meeting, it is important to provide immersive display with high resolution image to cover up the field of view and provide to the local user the same environment as that of remote site. To achieve these, a high resolution image needs to be transmitted for reconstruction of remote world, and it should be displayed using a tiled display. However, it is hard to transmit high resolution image in real time due to the limit of network bandwidth, and so we receive multiple images and reconstruct a remote world with received images in advance. Then, we update only a specific area where remote user exists by receiving low resolution image in realtime. We synthesize the transmitted image to the existing environmental map of remote world and display it as a stereo image. For this, we developed a new system which supports GPU based real time warping and blending, automatic feature extraction using machine vision technique.

Recently, interest in rural tourism for urban dwellers has increased, and rural communities are chosen as tourist destinations. Under these circumstances, the study was designed to analyze the effects of the quality of service at rural stay sites on customer satisfaction and recommendation intention. The analysis method analyzes the demographic characteristics of the survey participants and characteristics of participation in rural stay. And the quality of service for the experience of rural stay was analyzed with SERVQUAL'S five-dimensional type, reliability, assurance, responsiveness, empathy, tangible and customer satisfaction, intent of recommendation and regression. Major analysis shows that the survey subjects were found to have an average age of 41.8 years, 49 to 59 years old, and a high degree of university graduation. And as characteristic of participation, the form of company was family and relatives, the form of family meeting was many summer, the reservation was Internet, and payment by cash and card were many. As a result of the hypothesis testing, reliability, assurance, responsiveness, and empathy among the quality of service of rural stay were affected in customer satisfaction. In addition, the quality of service and the intent to recommend it were statistically significant, reliability, assurance and empathy. Therefore, it is deemed necessary to make efforts to improve service quality as the quality of service at rural stay places has relevance to customer satisfaction and recommendation intention.

This study targets Korean culture theme park in Yeongju-Zone and World confucian scholar culture park in Bonghwa-Zone among the Three Major Cultural Areas Projects supervised by Ministry of Culture, Sports and Tourism. The study analyzes the Historical and Cultural Authenticity of each project on the basis of the reports and the report materials for meeting with related organizations. The results of the study are drawn as follows. First, through the theoretical consideration, this study drew the types of authenticity: originality, identity, specificity and visibility, which are evaluation items on the Historical and Cultural Authenticity. Second, Bonghwa-Zone succeeded in acquiring originality with tangible cultural properties but Yeongju-Zone chose a project site without it. Third, with originality, Bonghwa-zone was evaluated as having resources and concept with high traditional culture connectivity and fulfilled identity. It led the feature showing the high affinity between originality and identity. Fourth, compared to the projects of Andong-Zone in the Three Major Cultural Areas Projects, these two projects failed to acquire the distinctions since the primary and the secondary influence area and major facilities & programs coincided with those of the projects of Andong-Zone. Fifth, compared to Bonghwa-Zone, Yeongju-Zone realized visibility faithfully by the conceptual flexibility of "Korean Culture" and a large-scale development. Sixth, in terms of the Historical and Cultural Authenticity of project plan, it is evaluated that Yeongju-Zone and Bonghwa-Zone only fulfilled visibility and specificity respectively.
