  • Recently, there has been rising concerns to integrate and connect a developed spatial information services without consideration of location in the heterogeneous distributed environment. The Open GIS Consortium provides system architecture model related to open web service for spatial information. This paper discusses the issues related to the web service framework for spatial information services using standards of Open GIS Consortium. In particular, we concentrate upon the WRS that support the runtime discovery and evaluation of resources. The technology for integration of spatial information services is expected to get synergy effect and overcomes limit of individual development of each spatial information technology. Also this system provides the interoperability and the reusability and prevents the duplication development of system.

  • This study looks for the service factors influencing to conversion among the domestic telecommunication companies and finds out the effect which the switching benefit affect the customer satisfaction and the switching intention. Eight service factors of the telecommunication company such as usability, call quality, terminal quality, auxiliary service, rates, after service, application and brand image are selected and verified using the structural equation model. Auxiliary service, rates and brand image give positive (+) effects to the customer's satisfaction, but the application gives negative (-) effects to the customer's satisfaction. Switching benefit affects significantly to the switching intention, but not to the customer satisfaction. The customer satisfaction gives a positive effect to the switching intention. The telecommunication service factors influence to customer satisfaction and switching intention, and switching benefit also influences to switching intention. It was analyzed that the significant influencing service factors were a little different among the telecommunication companies.

  • In this paper, authors propose the sensor fusion system that can recognize multiple 3D objects from 2D projection images and tactile information. The proposed system focuses on improving recognition performance of 3D object. Unlike the conventional object recognition system that uses image sensor alone, the proposed method uses tactual sensors in addition to visual sensor. Neural network is used to fuse these informations. Tactual signals are obtained from the reaction force by the pressure sensors at the fingertips when unknown objects are grasped by four-fingered robot hand. The experiment evaluates the recognition rate and the number of teaming iterations of various objects. The merits of the proposed systems are not only the high performance of the learning ability but also the reliability of the system with tactual information for recognizing various objects even though visual information has a defect. The experimental results show that the proposed system can improve recognition rate and reduce learning time. These results verify the effectiveness of the proposed sensor fusion system as recognition scheme of 3D object.

  • This paper presents ergonomic approaches to editing and evaluating content for 3D displays. Two systems, a nonlinear editing system and an evaluation system, were developed to improve viewing safety and comfort for 3D content observers and provide better usability for the creators from the viewpoint of ergonomics.
