本論文目的在於提出一個適用於普及運算環境之應用程式框架。在此框架中，我們將服務分為兩大類: Active Services以及Passive Services, 並且將現實環境中情境的改變，視為”Event”. 利用這些Events來驅動Active Services, 主動的為使用者來提供服務。接著利用此框架建立一個應用程式”Smart Campus”. 以校園內的活動為例，列舉出校園當中有哪些活動，並將這些活動以Event的格式，也就是”人、事、時、地、物”五個欄位來表示。而Smart Campus能夠藉由蒐集並且解讀這些Events，瞭解整個校園目前的狀況，進而通知相關人員。也就是說，Smart Campus具有普及運算的特性，即Fully Distributed, Context-Awareness. 把電腦運算融入到校園生活活動內。

In this paper, we propose an application framework for pervasive computing. In this framework, we divide services into two types: Active Services and Passive Services and we will take the changes in the real situation as "Event". By using the events, the Active Service will be driven so that it can offer the service for the user automatically. Then, we can set up an application called "Smart Campus" based on the framework. Take the activities in the campus as an example, the first step will be list all the activities in the campus and present them with Event Format, which means all the activities will be shown as “Who, How, when, where, What”. Therefore, "Smart Campus" can see the whole pictures campus by collecting and interpreting these events. Then, it can inform the related staff. In other word, Smart Campus have the character of pervasive computing, which means it is Fully Distributed, Context-Awareness and can blend the computing into daily life.
