  • This paper presents the model that integrates an SDL system and a CORBA system using mapping rules between method and signal for developing embedded systems connected with internet. In order to support communication between the two different systems (SDL and CORBA), it is essential to secure the conversion interface between SDL communication protocol and CORBA communication protocol. In this paper, IDL is adopted for the communication interface and the conversion of the communication protocol between the two systems, and the IDL compiler automatically generates the interface for protocol interoperability. The proposed model adopts middleware on the subpart of the SDL based legacy system, and hence, supports the service on the distributed system, regardless of the environment and location of the server system.

  • 대부분의 입체 영상물은 단지 화면을 입체로 보여주는 것만이 목적이다. 그러나 만약 입체 영상으로 표현된 가상 물체를 손가락을 뻗어 실제로 만져볼 수 있다면 현실감은 더욱 증가할 것이다. 본 연구에서는 입체영상 장치로 만든 가상 비누방울들을 실제 자기 손가락으로 터뜨리는 듯한 느낌을 가질 수 있도록 해주는 가상 현실 게임 시스템을 만들었다. 이 때 두 개의 위치/방향 센서를 이용하여 손가락 끝과 머리의 움직임을 추적하여 가상 공간과 현실 공간의 두 좌표계를 서로 일치시켜 볼 수 있도록 하였으며, 자체 제작한 진동촉각 장치를 이용하여 비누방울을 터뜨릴 때 손가락에 약한 진동 촉감을 제공하여 실제로 자신이 비누방울을 터뜨리는 듯한 느낌을 갖도록 하였다. 이러한 시도를 통해 입체영상 기술을 이용한 가상현실 게임에서의 진동촉각 장치의 활용 가능성을 확인하였다.

  • This paper deals with the design and implementation of an Ethernet-based communication protocol to be used in PC-based I/O interface systems. Recently, the performance of PC systems is being highly improved and Ethernet is used as the stable communication network over the world. We develop a new protocol driver with the capability of accessing Ethernet directly using NDIS(Network Driver Interface Specification), the network interface standard of Windows O.S. in PC, and install it at the application layer of the protocol structure. Its major roles are the supplement of CSMA/CD algorithm, the effective use of the long data frame of Ethernet, and the real-time transmission of data frames. This paper represents the possibility of the real-time control network and systems based on PCs and Ethernet.

  • For smart mobile devices, the wireless communication module is one of the hardware modules that consume the most energy. If we can build a multi-channel multi-interface environment using heterogeneous communication modules and operate them dynamically, data transmission performance can be highly improved by increasing the parallelism. Also, because these heterogeneous modules have different data rates, transmission ranges, and power consumption, we can save energy by exploiting a power efficient and low speed wireless interface module to transmit/receive sporadic small data. In this paper, we propose a power efficient data transmission method using heterogeneous communication networks. We also compared the performance of our proposed scheme to a conventional scheme, and proved that our proposed scheme can save energy while guaranteeing reasonable data delivery time.

  • Recently, the necessity of rapid response to social problems such as disasters and quarantine arising from the complex and diverse social structures has emerged. As the number of large buildings increases, large-scale human damage is expected in the event of a disaster such as fire. To solve this problem, efficient control must be achieved through interfacing with various equipment and facilities installed inside the building. In this paper, we intend to study the interface method for various facilities in the building for efficient control. In detail, the facility standard model is defined by examining the status and specification of building. In addition, we intend to design and propose a standard facility communication data frame to support the protocol applicable to this model.

  • In this paper, an efficient technique is proposed to integrate the 3D user interface with the tiled display system in PC cluster environment. In the developed 3D user interface software, various menus are provided to increase the user friendliness of the interface, including the several model-control-commands. To eliminate the noise produced from the 3D user interface devices, the box filtering algorithm is employed. Further, a communication splitting algorithm, which is a kind of asynchronous communication method, is proposed to reduce the motion delay between the 3D interface and the tiled display system, and its efficiency is validated through the benchmarking tests.

  • The importance of communication which is oriented to interaction, fusion and connection is more increased in the post-information society. The information environment is already realized as interface to reach immediately and freely to the databased information and knowledge. The contemporary libraries execute very important roles as an intellectual infra of modern times to deliver the great human achievement and create new culture. In the mean time, the rapid information-oriented society and the development of digital technology bring out big change in the traditional dispatch and receipt method of information. For this reason, libraries as the community space of visitors integrates physical space - electronic space and reconstructs new temporary culture and value to build the new interface that connects human to human, human to space and human to information. On the premise of these awareness, this study analysis the creative interface factor of Tama Art University New Libraries in Ito Toyo in order to research the function and the application method of modern libraries. And the results are follows. 1)We can make sure the significance of communication and the integration consciousness between digital technology and analogue sensitivity that is the characteristic of the post-information society. 2)We can classify for the creative interface factors by the character as space factor(Arcade, Gallery, Lounge, AV Booth, Cafe), facility/equipment factor(Laboratory, Media, Bar, Info Shelf, Media Seat) and furniture factor(Carrel, Desk, Mag Table, XI Shelf). 3)We can see that these interface factors change the stream of library users and that the library is constructed for library users to create and discovery something easily from books and modern technologies. And we can realize also that these factors are creative installation to lead out naturally the latent liberty sense of users.
