Homework 3-27-2009

LBS(Location Based Service)最早起源於美國，在美國打911緊急電話的話，可以知道你的位置在哪，是以GPS為基礎的一種運用。移動應用便是於美國國防部建立的NAVSTAR全球定位系統，運用24顆衛星來形成三角定位，逐漸形成現在所看到的GPS系統，但是GPS系統是使用低功率、超高頻的無線信號傳輸，無法穿透建築物或高山。像Garmin、Magellan......等公司都在致力於GPS裝置的開發。

LBS不只可以告訴你目前的位子或接下來的方向，更可以透過LBS，讓你知道附近有哪些朋友，尤其在人身地不熟的地方，能找到一個朋友真的是ㄧ件很方便的事。

Skyhook 研發出一種LBS軟體，可以透過 Wi-fi signals，去找到自己的位置，也可以跟GPS系統一起搭配，使得GPS的定位速度更快。Apple's IPHONE and IPOD TOUCH也有搭配這方便的應用。

許多各領域的大廠，如手機大廠-NOKIA，瀏覽器龍頭-Google，微軟新堆出的Window 7系列，......等，也都開始投入資金，研究相關LBS的應用，可能不久之後，這種應用就會被廣泛的在電腦以及手機上使用。但也有些國家覺得這種服務並不被需要，如歐洲，所以他們在這方面的技術發展的非常緩慢，甚至快要沒落。我覺得，這個服務對於我來說，非常的方便，相信對許多人來說也是如此，或許有一天，歐洲國家也會一起加入這個行列。
