摘要
近年來，老人看護監視系統已經成為一個重要的議題。隨著老年人口的成長，看護系統漸漸被廣泛討論與應用。然後，目前市面上絕大部份的老人看護監視系統，都必須要花費昂貴的開銷，不僅僅是金錢上的消費，精神上的消耗更是驚人。這類的系統有兩個重要的主題是必須要被重視的：系統必須不引人注目，以及其使用的普遍性。因此，我們也嘗試著將這兩項重要的議題，利用我們的系統來實踐。
在這篇論文裡，我們使用了SR-4000 image ranger這台攝影機，來擷取影像的深度資訊和強度資訊。利用這些有力的資料，我們建立了一個擁有顫抖偵測、疼痛反應偵測，和手勢辨識三種功能的老人看護系統。這個攝影機是一個呈長方體的小方塊。裡面安裝有紅外線發射器以及接收器。不僅可以很簡單便利的安裝在病床或是睡床上方適當的位置，而且不會引人注目，造成使用者的困擾。這個系統設有兩種緊急通知功能和利用手勢辨識的使用者操作介面，不必配帶任何額額外的裝置。長時間觀察的功能與較低價格的設備，也同樣被使用在這個系統當中。大部分對於這樣類型的設備有需求的老年人，都是需要長時間待在床上休息，並且沒有自己維生能力或是沒有大量的財富。這個系統花費了較一般系統便宜的金錢，而且能夠每天24小時的長時間運作，不但能夠滿足監視安全的重要性，也能夠達到普遍性和不引人注目性的原則。基於前面提到這些功能與優點，我們提出了這個系統和一些有趣的數據和結果。
