  • Due to the development of ICT technology, convergence reality contents are utilized as technology for providing services in various industrial fields by visualizing various information such as sensor information and shared information in a service platform showing only simple three-dimensional contents. Research is underway to reduce the weight of applications by transmitting the resources of the object to be enhanced to the network as the information and the contents to be provided increase. In order to provide resources through the network, servers for processing various information such as pattern information, content information, and sensor information must be constructed in a cloud environment. However, in order to authenticate data transmitted and received in real-time in a cloud environment, there is a problem in that the processing is delayed and a delay phenomenon occurs in the rendering process and QoS is lowered. In this paper, we propose a system to distribute cloud server which provides augmented contents of convergent reality service that provides various contents such as sensor information and three - dimensional model, and shorten the processing time of reliable data through distributed relay between servers Respectively.

  • As the mobile marketing through the smartphone has gradually increased, the smartphone application services using the AR marker, QR codes and augmented reality have attracted much attention. Furthermore the outdoor advertising is migrated to LED signage, which brings the visible light wireless communication technologies to the trial for mobile marketing. In this paper we present the implementation of AR marker-based URL access application services through smartphone camera using visible-light wireless communication technologies. We analyze the performance of the implemented system in terms of connection time and success rate.

  • In this paper, we proceed with the design and development platform for the development of the optimized applications to take advantage of the sensing techniques of the mobile device, so that this can proactively respond to the user's needs, and can provide access to a range of services. Ubiquitous environment based smart campus is active rather than passive, university will be able to promote the true personal customizable services. Campus tours through augmented reality will support more active university life in conjunction with a variety of services to promote actively utilizing the QR Code(2-dimensional bar code). In addition, we designed to develop a mobile application that can provide such a view and post announcements such as integrated system, through interoperability with existing bachelor's administrative (legacy) system.

  • Recently, the value and the status of the body that are due to the mobile wearable device have attracted attention globally confusing in media convergence age. The mobile wearable device connect worldwide that are networked to overcome the limitations of space and time, also it provide a great opportunity to be able to us to open a new cultural experience and value to the populace. In this study, spatial information acquired by the virtual reality 360 degrees camera around the Gangnam station. Also, extended spatial experience performed by use of virtual reality headset, smart phone connected to the Youtube platform. Sense of body can also lose its value due to voyeurism, it is facing the transformational period in civilization. In conclusion, through deep research into the intersections of technology and a human being for the future, maintaining the proper balance is the key. Therefore, this study identified the need for interdisciplinary research.

  • The u-GIS national land information providing technology is the technology which maximizes the application of u- GIS data through the national land information platform technique of the next generation web and provides a user with the on-demand national land information in the ubiquitous environment. Recently, as the environment emphasizing the web as a platform 'Web 2.0' emerges, the where 2.0 which is paradigm is diffused in the spatial information area. And the Geo-spatial Web technology develops in a center. Moreover, it is changed to the open platform of the user participation trend. And the consumer of the geo-spatial information is changed to the end-user center from the public institution. The geo-spatial technique is technologically faced with the new challenge. In this paper, we analyze the technical tendency about a paradigm, And we present the u-GIS national land information platform technique, the u-GIS national land information visualization technology, the u-GIS national land information GeoDRM integrative technique, and the u-GIS national land information mobile application technology as the essential elemental technology for overcoming this.
