dc.description.abstract 近年來隨著資訊科技的進步,無線感應裝置使用率的程度越來越高,感知應用已成目前資訊發展重要研究領域。在過去許多的情境感知系統都只使用單一情境感知技術去反應週遭的環境變化與使用者資訊,往往無法完整的描述目前環境之變化,系統給予使用者的資訊回饋也會有所侷限。 本研究提出以RFID(Radio Frequency Identification)技術為基礎的情境感知系統,並結合GPS(Global Position System)定位技術,發展出整合RFID與GPS訊息描述使用者情境資訊的交換格式。為了能夠對不同情境感知用戶端分享所擷取到之情境資訊內容,本研究進而發展以Socket網路技術情境資訊交換功能,並把情境資訊以SOAP(Simple Object Access Protocol)格式封裝,透過Socket技術進行傳送,來達成不同用戶端之間情境資訊交換的功能。除此之外,為了達到情境感知系統能夠根據使用者情境給予適當的資訊服務,本研究依據不同類型使用者情境透過Web Services技術實作了個別化服務-自動登入的功能,包括了「人」與「物」兩種不同類型的使用者情境應用。本研究並對所佈署的Web Services與在不同接收端情境資訊交換功能進行了分析,量測在有線網路環境下的傳送效率。透過本系統的情境感知技術,可以實現情境感知五大層面中「人」、「地」、「物」三大層面的資訊擷取與交換。 zh_TW
dc.description.abstract Along with the advanced of information technology, the wireless installment has been utilized more and more frequently in recent years. The context-aware application has become one of the most important research areas. In the past, most context-aware systems only use the sole context-aware technology to respond the environmental difference and the user information, in which is unable to describe the present change of the environment, and it gives limited feedback for users’ required information. In this research, we propose using RFID (Radio Frequency Identification) the technology as the foundation context-aware system, which combines GPS (Global Position System); developing the conformity of RFID and the GPS messages which describes the user context information exchange form. In order to fetch and share the different user client context-aware information, we develop the Socket exchange function, which is marshalled by SOAP (Simple Object Access Protocol) techology. In addition, based on this user’s context aware information, we implemented Automatic Login Function, to access the personalized services including "person" and "object". In order to evaluate the transmission efficiency of our proposed SOAP protocol, we analyed the transmission delay under wired network environment.Using our schema, we can realize three level of information fetching and exchange, that’s, ”the person”, ”the thing” and”the place”. en_US
