摘要

隨著手持式設備的普及化，手機已於我們生活中扮演著舉足輕重角色，以目前台灣手機使用已達到幾乎每個人皆有一支手機（甚至一支以上）的情形下，若能將導覽服務應用到現有的設備，將可以更加推廣手機的實用性及導覽的重要性，目前市場上的導覽服務皆是以一台觸控式螢幕內含所有簡介的資訊，但只能定點查詢、無可攜性也無立即性；另外在公家單位，較多是使用PDA，而每位顧客需先去服務台填寫資料再借用PDA，以PDA呈現導覽服務，但是這些皆由提供者額外提供這些設備供人借用，必然會增加硬體成本及管理維護成本，若能使用手機達成此項服務，在提供者而言可以減少成本支出，在使用者而言可以得到更即時的查詢資訊，以逹成雙贏的局面。
根據最早推廣藍芽產品的新力易立信（Sony Ericsson）調查，台灣消費者對諸如藍芽之類的新鮮高科技產品，市場接受度高居亞洲第一，在全球更排名前3名，以新力易利信 (Sony Ericsson) 而言，去年比前年藍芽產品銷售業績成長30%，2005年起每月更成長25-30%，目前市場佔有率達4成，銷售的手機更有6-7成內建藍芽功能。所以本研究運用藍芽協定為研究的傳輸工具。藍芽協定可以架構個人隨意網路，以本身為master，利用藍芽無方向性，也不需直線對準的特性，來傳輸資料，可以更加準確的傳給其餘slave裝置。
本研究將以實作建構一個在Linux平台上的傳播系統，此傳播系統的主要目的在於以不間斷式搜尋發現擁有藍芽的手持式設備，經系統比對記錄檔後，加以判斷再給予最新版本程式，另外導覽服務是應用JAVA跨平台的特性而設計出的應用程式經傳播系統傳送至消費者的手持式設備。

Along with the popularization of mobile device, mobile phone has become an important part in our daily lives. At present, in Taiwan, almost everyone has one mobile phone, even more than one. If navigation service can be added into present equipments, then it could promote the practicality of mobile phone and the importance of navigation. Nowadays most of the navigation service is using touch panel machine, but it can only provide inquiry service at fixed position without portability, and it is difficult to keep the data up to date. In addition, PDA is used mainly in the navigation service of government organizations. Every customer has to fill out application at service center to borrow PDA. These equipments are provided by authorities, not to mention the cost of hardware and management must be increased. If mobile phone can be used to receive navigation service, it would reduced much cost for the provider, and the user can obtain information immediately, thereby beneficial to both sides.
According to the survey of Sony Ericsson, which was the first to promote the Bluetooth products, the acceptance of Taiwan consumers on Bluetooth, which is a very new and high technology, is the first in Asia, and the third worldwide. In terms of Sony Ericsson, the sales of Bluetooth products have a growth rate of 30% as compared to last year. In year 2005, there is a 25-30% growth rate per month. Presently, it occupies 40% of the market, and 60-70% of their sales are the mobile phones with Bluetooth function built-in. Therefore, this research uses the Bluetooth protocol as transmission tool. Based on the undirectional nature of Bluetooth and its characteristic of no need to aim at straight line in transmitting data, the master device can transmit data to slave devices more accurately.
This research actually constructs a Linux platform of broadcasting system. The main purpose of this transmission system is to uninterruptedly search for handheld Bluetooth devices, through comparison with log files, it will decide whether to transmit the newest version of program. In addition, navigation service uses the “platform independence” of Java features to develop the application program. Therefore our proposed broadcasting system can transmit the navigation service to surrounding mobile phones with Bluetooth built-in.
