Well-set tabletops influence customers' purchase behavior or post-purchase behavior by making the quality and image of a restaurant distinguished and customers impressed. This study aims to investigate the relations between the perception of environment among physical environments of restaurants and psychological responses to their tabletops and consumers' attitudes in order to suggest new guidelines for table-setting. As a result, the direct relations between the perception of environment in the tabletops of the restaurants and consumers' behavioral intention indicated that the perception factors of tabletops affected consumer behavior and that these perception factors affected the formation of general attitudes among consumers through emotional and cognitive responses. This result shows that tabletops can be an important key in managing restaurants with changing customer needs. Therefore, it is expected that positive customer attitude can be made by provoking their psychological responses with unique and attractive tabletop settings.

In the prior works on tabletop systems, a projection-based tabletop surface is mostly used to display computer images, and the participants interact with the display surface by hand multi-touching or using some tangible objects. In this research, however, we developed the FishBowl game that employs a scalable tabletop tiled display with infrared camera tracking coupled with PDA mobile interfaces. The focus of this game is to enhance user interactivity and realistic experience by coupling the high-resolution tabletop virtual environment and PDA mobile interface. This paper describes the game design followed by the system design and its detailed implementations. It also discusses the system usability and recommendation for its improvements after interviewing game players and then concludes with future research directions.

Applications which are implemented on Table Top Display are controlled by hands, so that they support an intuitive interface to users. Users feel the real sense when they interact on the virtual scene in Table Top Display. However, most of conventional augmented reality applications on Table Top Display satisfy only visual sense. In this paper, we propose an interface that supports multi-modal sense in that tactile sense is utilized for augment reality by vibrating a physical control unit when it collides to virtual objects. Users can feel the collision in addition to visual scene. The proposed system facilitates tactile augmented reality through an air hockey game. A physical control unit vibrates when it receives virtual collision data over wireless communication. Since the use of tabletop display environment is extended with a tactile sense based physical unit other than hand, it provides a more intuitive interface.

Tabletop display can take the benefits of the interactive device due to its possible user friendly input and display facilities simultaneously. Using this device, immersive edutainment content is effectively implemented with the convenient interactive interface. So considering this usefulness, tabletop display can be a very efficient device for constructing the edutainment system. In this paper, we describe a digitalized cooking edutainment contents based on the tabletop display interface. Enjoying our contents, we use the intuitive touch gestures for handling a variety of cooking actions. In the education effects such as the immersive strengthening and co-operation, the proposed system is more efficient interface than any other existing system. We implement the contents with the tabletop display and make sure about the efficiency of our proposed system. In the future, we will add more gestures to enhance the applicability of the intuitive interactive interface.

In this paper, we propose the Table-top system for using educational contents. Table-top system that is matched visual information and interaction space offers easy and intuitive interface. Moreover, because the effectiveness of education is enlarged if the content for education intuitive recognizes and an interaction, the table top system is suitable. In this paper, the multi touch,that is the advantage of the table top system, was implemented in the content for education manufactured as a flash. This system can solve the member of the instinctive interaction between a user and the contents which was short in the system like the existing desktop.

This paper describes the iTABLE tabletop tiled display system which is designed for displaying high-resolution scientific visualization. Unlike other tabletop systems that typically use a projection-based single display, iTABLE system is suitable for visualizing and sharing high-resolution data, and it is capable of facilitating group interaction with interactive data visualizations on a table and distributed collaborative visualizations with other tiled displays. First, it surveys prior works on tabletop and tiled display systems as well as scientific visualization, and it describes the design and implementation of iTABLE system, and middleware and an infrared camera-based tangible user interface designed for iTABLE system. It will then discuss some high-resolution scientific visualization applications developed for iTABLE followed by conclusions and future research directions.

In this paper, we present a framework which enables users to interact naturally with hand gestures on a digital table. In general tabletop applications, one gesture is mapped to one function or command. Therefore, users should know these relations, and make predefined gestures as input. In contrast, users can make input gesture without cognitive load in our system. Instead of burdening users, the system possesses knowledge about gesture interaction, and infers proactively users' gestures and intentions. When users make a gesture on the digital surface, the system begins to analyze the gestures and designs the response according to users' intention.

본 논문에서는 테이블탑 디스플레이을 기반으로한 RealBook에 대하여 제안한다. 전자책은 일반 종이책이 아닌 컴퓨터를 이용한 가상의 책으로써 사용자가 독서를 하는 도중 동영상 자료를 보거나 배경음악을 들을 수 있게 해주는 멀티미디어 콘텐츠이다. 또한, 테이블탑 디스플레이 플랫폼에서 사용하므로 손의 직접적인 터치를 이용하여 전자책과 사용자 간의 좀 더 다양한 상호작용이 가능하도록 한다. 테이블탑 디스플레이에서는 손가락의 터치 점을 이용하여 다양한 제스처를 정의할 수 있어서, 사용자가 기존 입력 장치에 비해 보다 효과적으로 전자책을 체험하는 것을 돕는다. 본 논문에서는 제안하는 방법은 기존 전자책과 차별화된 상호작용 디지털와 아날로그를 결함한 책(Real book)으로써 전자책에 대한 새로운 방향을 제시할 수 있고, 미디어 아트와 스토리텔링 기법을 접목시켜 사용자에게 정보 전달뿐만 아니라 예술과 오락 등을 제공할 수 있다. 앞으로 컴퓨터와 사용자간의 상호작용을 원활하게 할 수 있어 다양한 어플리케이션 개발에 활용될 수 있고 향후 미래 지향적 시스템이 될 것이다.

본 논문에서는 터치 제스처의 인식을 위해 시도된 여러 방법 중 테이블탑 디스플레이상에서 HMM을 이용한 제스처의 학습과 사용에 대해 제안한다. 터치 제스처는 제스처의 획(stroke)에 따라 single stroke와 multi stroke로 분류할 수 있다. 그러므로 제스처의 입력은 영상프레임에서 터치 궤적에 따라 변하는 방향 벡터를 이용하여 방향코드로 분석될 수 있다. 그리고 분석된 방향코드를 기계학습을 통하여 학습시킨 후, 인식실험에 사용한다. 제스처 인식 학습에는 총 10개의 제스처에 대하여 100개 방향코드 데이터를 이용하였다. 형태를 갖추고 있는 제스처는 미리 정의되어 있는 제스처와 비교를 통하여 인식할 수 있다. (4 방향 드래그, 원, 삼각형, ㄱ ㄴ 모양 >, < ) 미리 정의되어 있는 제스처가 아닌 경우에는 기계학습을 통하여 사용자가 의미를 부여한 후 제스처를 정의하여 원하는 제스처를 선택적으로 사용할 수 있다. 본 논문에서는 테이블탑 디스플레이 환경에서 사용자의 터치제스처를 인식하는 시스템을 구현하였다. 앞으로 테이블탑 디스플레이 환경에서 터치 제스처 인식에 적합한 알고리즘을 찾고 멀티터치 제스처를 인식하는 연구도 이루어져야 할 것이다.

In this paper, we describe about interactive electronic book utilizing tabletop display interface and digi-pet. Because of this system can define a lot of gestures using touch point of finger, help that user experiences electronic book effectively more than existent input device. Also, support 1 users in 1 input device in existent mode, but this system can expect various effect because support Multi-user. The digi-pet(digital pet) is physical tools that convey emotion between tabletop display platform and user. And this shows various results acting as assistance because becomes master of story of imagination and participate directly on talk and makes change of story. In this paper, we described about oriented electronic book system the future that combines tabletop display and Digi-pet. This system is expected that the usefulness is increased by leaps and bounds along with technology development forward.
