This paper provides a user interface for mutual collaboration table top display technology. The biggest difference is that the existing interface with existing research through a single device to multiple users simultaneously enabled oriented way of face to face. On the other hand, in collaboration important deadline table top display device to device-oriented approach in which the order of one of the devices require users. Collaborative research is actively underway, but to do so focused still many challenges in this situation. This paper provides for collaboration on global trends on a table top display interface for more mutual collaboration with the user interface for about checking out on a table top display, currently being developed by a collaboration among users against a table top display technology.

In this paper, we propose an object control system on table top display to support augmented reality in which objects in real-world control computer-generated data. We developed LED-based object control system over table top display so that it is capable of controlling networked table top display. The LED-based object control system supports more natural interactive interface. In this paper, infrared LED is used to implement the object control device to be recognised by table top display. We applied LED-based object control system in air hockey game where a team has a point if their puck goes to opponent's net on a table. Since users can control objects in cyber world with the proposed object control device, it is realized augmented reality.

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.

Recently, the development of IT technology, utilization of smart devices 3-5-year-old infants Upon smart device penetration rate per household increases has also sharply increased. In this paper, the educational contents for kid are considered and implemented by reflecting this trend. Content that has been produced in this paper are based on learning theory of constructivism, was to be performed naturally learn the content of the table-top display of applying the NUI technology. Also, the content creation that can help you learn infants through experiments crafted tabletop display interface content, it is believed to be the basis for the improvement of usability.

본 논문에서는 실감형 요리 시스템의 제작에 대하여 기술한다. 실감형 요리 시스템은 요리를 만드는 과정을 컴퓨터를 이용해 가상적으로 체험해 볼 수 있게 한다. 증강현실 기술을 이용, 모의부엌에서 요리 재료 카드를 인식함으로써 요리재료를 요리 용기에 투입하고 투입된 요리 재료는 증강현실 부엌에 나타나게 된다. 또한 멀티 터치가 가능한 지능형 인터페이스 플랫폼인 테이블 탑 디스플레이를 기반으로 증강현실 오브젝트와 사용자가 서로 상호작용할 수 있도록 한다. 테이블 탑 디스플레이에서의 터치와 hand gesture를 인식하여 맨손의 손동작에 의해 상호작용을 구현한다. 이 시스템은 특히 어린이들을 대상으로 하여 실감나는 요리 체험을 할 수 있으며, 요리 과정을 보다 효과적으로 학습하는데 활용될 수 있다.

Smart Dining Table is an ongoing project in our Interaction Design Lab. It is a table top display designed to facilitate dining process. Smart Dining Table uses touchable interface to interact with users, providing a new, interesting and efficient experience in dining process. In GuangZhou, the south city of China, Yam Cha is a traditional and local way of entertainment in which normally elders gather together with friends or relatives to have tea and snack, and most importantly, to chat. Yam Cha has a long history in China, and Guangzhou has developed its own unique "Yam Cha" culture. In this paper, we discuss about previous research we did on Yam Cha in GuangZhou, and the approach we propose to manage and analyze issues related to dining table to help designing specific version of Smart Dining Table which can fit right into the Yam Cha process and cultural environment.

In this paper, we designed a tabletop display which enables two viewers each to see a different image simultaneously within his/her defined viewing zone. In order to construct the designed viewing zones, we found the basic design conditions for a parallax barrier with a commercial LCD panel. As the viewing zones for two viewers are formed with only two view-point design, the interval between the center positions of each viewing zone and the width of each viewing zone are small compared to designed values. We analyzed the primary cases, introduced two modified design methods to enlarge the interval and the width of the viewing zones, and simulated their characteristics. As designed with six unit view-point and each viewing zone of each viewer is formed with a merged view-point, we found that adequate interval and width of viewing zones can be made, and we verified it in comparison with the tabletop display module that we fabricated.
