良好的智慧家庭概念，在居家環境內應要可以環境狀態來反應使用者偏好來提供不同的服務。本研究的目的在於透過服務決策運算的方法改進目前智慧家庭中對於各式情境服務的提供與運作。現行的智慧家庭應用裡，大多由系統開發者設計了固定操作模式或特定的服務供給。此方法不僅僅造成智慧家庭系統無法輕易的維護與更動外，對於使用者而言卻是只能當作消費產品來使用，無法達到真正的情境感知目的。本研究以規則式的服務描述為基礎，提出了智慧家庭的服務規則推論引擎的實現，其掌握空間內各種情境資訊的變化來判斷居家環境中是否有合宜的條件產生。而經以規則式的服務描述，也供給了使用者一個服務設置的介面，讓使用者可依據個人偏好來訂立應用於智慧家庭的服務操作。系統將即時地由感測裝置攔收情境資訊，從該情境資訊裡，藉由與服務規則的條件進行比對，利用這些條件內容找出符合當下情形的服務選項，並提供給使用者於該狀況下較為合適的操作行為，以達到智慧家庭中的情境感知目標，同時也改進了目前智慧家庭系統的服務提供模式。最後以實驗展示驗證了本論文所實現的系統可以根據實際環境裡的狀態計算出合適的服務並提供於智慧家庭內。

An ideal concept of smart home should provide proper service in accordance with user's preference. In addition, it should ensure appropriate responses to context change in the home environment. To achieve these objectives, this paper proposes a Context Aware Service Platform (CASP) with reasoning mechanism for providing a personalized smart home. This paper designs a rule-based template which defines the relation between environment context and service. The core of the platform, rule-based engine, suggests a reasoning service which reacts to context change in environment. Demonstration shows that the appropriate service can be configured in the configurable rule-based engine and later automatically invoked by considering the user’s preference setting, sensor status, user activity, and presence time from smart home environment.
