  • In this study, it is the study of foreign tourism content information providing utilizing mobile indoor location information services. In particular, we compared the Web App used in Osaka, Japan. Widespread use of smartphones in the world increases, it is changed to free travel of individuals from group travel. Tourists cultural complex shopping mall is able to travel in a room is increasing. By utilizing the services of the guidance location based on the room, it is possible to easily obtain the discount coupon information, tourism content. Also, it is possible to grasp the movement path and disaster relief information. Osaka Japanese tourists increased after the earthquake in Tokyo. So we compare the difference in Osaka web and applications. If improving the indoor location information service method of domestic if it would help foreign tourists attract. In addition, it will give a big impact if there is a fusion of the Internet of things.

  • 빠른 속도로 확산되고 있는 모바일 기기는 카메라, GPS, RFID 등과 같은 다양한 센서를 장착하고 Wi-Fi, WiMAX, WiBro 등의 무선 네트워크를 지원하는 형태로 발전하고 있다. 이러한 발전으로 사용자는 언제 어디서나 주변의 컴퓨팅 자원을 이용할 수 있게 되었고 모바일 기기의 서비스는 주변의 센서 또는 임베디드 컴퓨팅 장치로부터 수집되는 다양한 주변 환경 정보와 시스템 상태정보, 네트워크 상황정보 등의 디지털 정보를 이용하여 주변상황인식(context awareness)이 가능한 스마트 서비스로 발전하고 있다. 주변상황인식을 위하여 서비스는 주변에 존재하는 다양한 장치를 효율적으로 검색하고 이질적인(Heterogeneous) 장치와 정보의 표현 및 전송에 대한 호환성이 필요하다. 이러한 문제는 규격화된 프레임워크의 사용으로 해결할 수 있으며 상황정보의 관리 기능을 추가하여 서비스 개발의 생산성을 높일 수 있다 본 논문에서는 모바일 컴퓨팅 환경에서 상황정보의 제공과 사용에 적합한 프레임워크로서 MoCE(Mobile Context Exploerer) 아키텍처를 설계하였다. MoCE 는 상황정보의 수집, 변환, 분류, 통합 등의 기능을 제공하고 모바일 환경의 특성에 기인한 상황정보 발견 및 전송 프로토콜을 설계하여 사용하고 있다. 또한 Surround multiCam 서비스 예제를 구현하여 제안한 아키텍처의 안정성 및 성능을 실험하였다.

  • In this study, author analyzed the overview and the convergence time of Fixed solutions (<15cm) of OmniSTAR, one of SBAS(Satellite Based Augmentation System) as WADGPS (Wide Area Differential GPS), which can compensate the drawbacks of the existed GNSS (Global Navigation Satellite System) that require the expensive receiver and is impossible to position in case of the radio interference in urban sometimes. As a result, the test shows that the less than 15cm 3D standard deviation converges in 39 minutes at Dynamic mode and 28 minutes at Static mode. It is expected that we can apply OmniSTAR to a variety of fields such as LBS(Location Based Service), mobile positioning, and the geo-spatial information industry that does not necessarily guarantee the high position accuracy.

  • Augmented reality (AR) is a popular service in mobile devices, and many AR applications can be downloaded from app stores. As TV broadcasting has continued to integrate with the Internet, it has become an area in which the AR concept is able to reside, although in a simple form, such as an advertisement placed in the static region of a scene. There are some restrictions against TV broadcasting realizing AR since TVs are fixed devices and typically do not have GPS, geomagnetic, or acceleration sensors, which are standard equipment in mobile devices. However, the desire to experience AR on a large TV screen has triggered research and development for an ideal AR business model and service type. This paper introduces several use cases for augmented broadcasting services and also presents an augmented broadcasting metadata scheme designed for a broadcasting environment. We also verify some of the use cases and an augmented broadcasting metadata scheme in an implemented augmented broadcasting system based on a hybrid TV platform.

  • Contrary to the traditional text-based information, 4S(GIS,GNSS,SIIS,ITS) information can contribute to the citizen's welfare in upcoming era. Recently, GSIS(Geo-Spatial Information System) has been applied and stressed out in various fields. As analyzed the data from GSIS arena, the position information of objects and targets is crucial and critical. Therefore, several methods of getting and knowing position are proposed and developed. From this perspective, Position collection and processing are the heart of 4S technology. We develop 4S-Van that enables real-time acquisition of position and attribute information and accurate image data in remote site. In this study, the configuration of 4S-Van equipped with GPS, INS, CCD and eye-safe laser scanner is shown and the merits of DGPS/INS integration approach for geo-referencing is briefly discussed. The algorithm of DGPS/INS integration fur determination of six parameters of motion is eccential in the 4S-Van to avoid or simplify the complicated computation such as photogrammetric triangulation. 4S-Van has the application of Laser-Mobile Mapping System for three-dimensional data acquisition that merges the texture information from CCD camera. The technique is also applied in the fields of virtual reality, car navigation, computer games, planning and management, city transportation, mobile communication, etc.

  • Purpose - This thesis aims to propose a method to help financial institutions improve their customers' convenience online and offline through a Bluetooth based App using the tool of a beacon. The emergence of smartphones in the 21st century and their increasing use makes it possible to search for information easily. Research design, data, and methodology - With the short-distance Bluetooth technology for smartphones, which finds users within a radius of 50m to provide the functions of message transmission and mobile payment, users can access information services and use mobile coupons in certain premises. Thus, beacon-based O2O technology has been developed. Results - This study offers a method of attracting customers through an O2O marketing strategy that overcomes the existing limitations of Web and Offline media. Conclusions -Since beacon technology has the advantage of more accurate positioning than GPS, financial institutions provide their product information for users through the basic function of a beacon, using an O2O (Online to Offline) marketing solution and, therefore, effectively enable customers to make relevant payments online and conduct their financial actions offline.

  • In this paper, we propose an intelligent marketing service system that can provide custom advertisements and events to both businesses and customers by identifying the location and contents using the ultrasonic signals and feature information in voice signals. We also develop the encoding and decoding algorithm of ultrasonic signals for this system and analyze the performance evaluation results. With the development of the hyper-connected society, the on-line marketing has been activated and is growing in size. Existing store marketing applications have disadvantages that customers have to find out events or promotional materials that the headquarters or stores throughusing the corresponding applications whenever they visit them. To solve these problems, there are attempts to create intelligent marketing tools using GPS technology and voice recognition technology. However, this approach has difficulties in technology development due to accuracy of location and speed of comparison and retrieval of voice recognition technology, and marketing services for customer relation are also much simplified.

  • 본 논문은 차량과 보행자 간 충돌 사고를 예측하는 V2P(Vehicle to Pedestrian) 서비스에서 보행자 휴대기기의 데이터 전송 시점을 동적으로 계산함으로써 불필요한 통신을 감소시켜 에너지 효율을 향상시키는 것을 목적으로 하며, MEC(Mobile Edge Computing) 기반 V2P 서비스를 제안하였다. V2P 서비스에서는 보행자와 차량 간 충돌 가능성을 예측하기 위하여 두 객체의 실시간 GPS 데이터가 요구된다. 이때 보편적으로 보행자에 비해 차량의 이동속도가 더 빠르기 때문에 보행자가 빠르게 이동해 들어오는 주변 차량에 발견될 수 있기 위해서는 자신의 위치에는 의미 있는 변화가 발생하지 않았더라도 차량 이동속도에 맞춘 빠른 주기로 차량 혹은 중앙 클라우드 서버로 자신의 데이터를 송신해야만 한다. 이 과정에서 보행자 휴대폰의 에너지가 급속하게 소모된다. 따라서 본 연구는 이러한 문제를 해결하기 위하여 MEC 서버를 배치한 V2P 서비스를 제안하였고, 보행자가 본인의 상태 정보를 활용하여 효율적인 다음 데이터 전송 시점을 계산할 수 있는 동적시점계산 알고리즘을 제안하였다.
