  • The most critical element in the real-time operation of RFID application programs that are suitable for the mobile environment is the RFID middleware, made exclusively for mobile handsets, which processes collected data on a real-time basis and sends only the useful information to the application client. In this paper, we intend to design and implement a mobile RFID middleware system that supports the mobile handset environment for real-time based processing of the necessary data in the mobile environment. The proposed mobile RFID middleware system includes a mobile reader interface that collects the tag data, a mobile filtering engine that processes the tag data into more meaningful data that is sent to the application interface, and finally the mobile application interface that supports the m-SOAP application access protocol for interfacing with existing mobile applications. The filtering speed of the newly-developed middleware engine was found to be suitable for the characteristics of mobile handsets.

  • Due to the increased use of mobile devices, there is a lot of discussion on mobile accessibility. Mobile accessibility means that everyone, who includes the disabled, the elderly people, can easily use the functions of mobile devices. In this paper, we presented and implemented a mobile interface using a speech I/O APIs to improve the accessibility. The proposed interfaces are implemented on Android platforms and they used speech recognition and text-to-speech APIs supported as built-in services. In addition, to facilitate the internet access for visually impaired or blind people, we also implemented the web browsing application (web reader).

  • 최근 모바일 RFID 분야는 기존의 RFID 서비스와 이동통신 서비스가 융합하여 사회 전반에 걸쳐서 다양한 연구가 진행되고 있다. 그러나 핵심 소프트웨어인 미들웨어 분야에서 기존의 RFID 미들웨어는 기능이 너무 복잡하여 시스템 자원이 한정되어 있는 모바일 RFID 서비스에는 적합하지 않다. 또한 특히 RFID 미들웨어는 리더에서 발생된 태그 정보를 응용프로그램에게 전달하는 소프트웨어로 많은 글로벌 IT 기업과 연구소에서 연구되고 있다. 그러나 기존의 이러한 미들웨어에 관한 연구는 태그를 식별하기 위한 서비스에 초점이 맞추어져 모바일 RFID 서비스를 위한 미들웨어의 구조로는 적합하지 않다. 본 논문에서는 기존의 RFID 미들웨어의 문제점을 알아보고, 모바일 RFID 서비스에 최적화된 미들웨어의 요구사항을 분석하였다. 그리고 모바일 RFID 미들웨어의 핵심 컴포넌트와 상호간의 인터페이스를 설계하였다.

  • RFID(Radio Frequency Identification) 기술은 사물에 전자 태그를 부착하여 무선 인터페이스를 통해 사물의 정보를 자동으로 취득 할 수 있는 기술이다. 물류의 재고관리나 자동화 처리를 위해 주로 사용되었으나 최근에는 Cellular phone, PDA등 휴대용기기 에 RFID리더가 탑재되어 기존의 응용 이외에 다양한 서비스를 만들어 내려는 시도들이 나타나고 있다[1],[2]. 이는 궁극적으로는 모든 사물에 컴퓨팅 및 통신 기능을 부여하여 언제, 어디서, 무엇이든 통신이 가능한 환경을 구현함으로써 이제까지 사람 중심(Person to Person)에서 사물 중심(Machine to Machine) 정보화 사회로의 새로운 변화 시도이며 RFID기술은 진정한 Ubiquitous세상이 만들어지기 위한 주요 기술로서 지속적으로 발전되고 적용되어야 할 기술임이 분명하다. 이러한 사회적인 요구에 만족하기 위해서 RFID 기술도 변화하고 있고 새로운 기술적 이슈들이 나타나게 되었다. 본고에서는 RFID 기술의 변화를 알아보고, 특히 UHF 대역 RFID 리더가 Cellular phone에 내장되기 위해 소형화 및 저전력화가 되면서 발생하는 문제와 이의 해결방안을 살펴보고자 한다.

  • As the eBook market grows fast recently, various eBook viewer solutions such as hardware viewers and software readers came out to the market. We can, however, hardly find mobile eBook interfaces for the reading disabled people who have difficulties in reading for their visual impairment or learning disabilities, or dyslexia. An eBook viewer interfaces for the reading disabled people should be carefully and distinctively designed because the reading disabled people cannot use normal versions of eBook viewer. In this paper, we suggest a eBook viewer interface model to make the reading disabled people read eBooks easily. Depending on the type of the reading disabled people: the full blind, the almost blind, the just learning disabled, our model provides an adaptive interface to make them read eBooks effectively. In addition, unlike the existing simple audio books, we also support annotation systems to make the reading disabled people interact with eBook viewer. To show the effectiveness of our model, we implemented an eBook viewer prototype on an android-based mobile device. We are sure that our model and implementation can make the reading disabled people, who is 10% of all the domestic people, read eBooks effectively.

  • The RFID (Radio Frequency Identification) technology is a non-contact identification system which can wireless reading of information, by attaching tags on objects; various applications of the technology are feasible throughout a dive of industries, and researches are currently under way. Recently, in connection with the wireless communication industry, application service models conveying information to the users through mobile devices with RFID readers were suggested. Such application service based on mobile RFID technology requires schema that models the form of data. Therefore, this study analyzes the mobile RFID application service model that will be serviced in the mobile environment, functions and elements of the protocol, and the interface, designing a language to process the data and express contents in the said service models, and we simulated the service for test it.

  • The existing patient monitoring system when the patient want own information. The patient confirm information through the medical institution. But the patient monitoring system based on the U-Healthcare, the patient always confirms own information through the mobile device including rfid reader. The patient need RFID middleware design to provide wanting service when the RFID reader read patient's tag information. The RFID middleware is consisted of RFID module, ARM processor and RS-232 interface. The RFID module is used to be inputted user information and RS-232 interface pass information by RFID middleware. Also, This system is embodied by specific patient monitoring system using embedded exclusive use ARM processor. In this paper introduces concept and action principle of RFID middleware and embodied patient monitoring system that use Qt.

  • This system configures a position Sensor as installing on the ship and a guidance system docking of ship what distinguish of the ship about the use and size. The maintain system is received the result of distinction via UWB reader. This system send a information of ship of docking position to user. Thus it suggests the safety to prevent from crash among ships and saves energy and stop waste. The proposed system periodically updates the information of docking position of the ship and monitors in real-time according to the user's request from personal mobile devices. In this paper, we implement of a guidance system Testbed for docking of the ship using position UWB sensor. And user is provided convenience to find easily user's ship in docking area through user interface with Java. Addedly it is possible to prevent ship theft.
