使用智慧穿戴裝置應用於跌倒偵測及事故重現之設計與實作

跌倒偵測是醫療照護領域上一道重要議題，跌倒後通常會在心裡以及生理上造成影響，特別是對於老人家的影響情況更是嚴重。在本研究中，我們提出了利用智慧型手錶來實現一跌倒偵測系統，所設想的情境為監護老人家於住家是否有跌倒情事發生，當確立跌倒事件發生後，我們設計一套有三個救援步驟的流程：第一步為以聲音訊息提示使用者是否需要救助，如果不需要，使用者即手動取消救助機制；第二步為確認需要救援後，會發送GCM通知給照護人員，讓照護人員第一時間得到訊息；第三步為照護人員收到通知後，可以通過重建事件發生功能，得知推測傷患跌倒情形及位置，讓傷患盡速得到醫療照護。為了實現以上程序，首先我們設計一套基於使用智慧型手錶的跌倒偵測演算法，所設計之演算法使用加速度數值來判定與分析跌倒進程，並利用SMV概念來判斷使用者是否跌倒以及是否需要救助。本系統亦利用iBeacon室內定位技術及行人航位推算概念來回報使用者在室內的路徑軌跡資訊，該資訊可供照護或照護人員能推估跌倒情事可能發生之原因，我們的實驗成果應證所設計之方法能有效地偵測跌倒偵測及重現事故。

Fall detection is an important issue in the field of medical care, which usually affects her heart and physiology, especially for the elderly. In this study, we proposed the use of intelligent watches to achieve a fall detection system, the scenario envisaged for the elderly in the home whether there is a fall occurred, when the establishment of the fall after the incident, we have designed a set of three rescue steps The first step is to prompt the user if the need for assistance, if not, the user manually cancel the rescue mechanism; the second step to confirm the need for rescue, will send a GCM notice to the care workers, so that the care of the staff The third step for the caregiver received a notice, you can rebuild the event function, that the risk of falls and the location of the situation, so that the injured as soon as possible medical care. In order to achieve the above procedures, we first design a set based on the use of smart watch fall detection algorithm, the algorithm used to calculate the acceleration value to determine and analyze the fall process, and the use of SMV concept to determine whether the user falls and need Rescue. The system also uses the iBeacon indoor positioning technology and the pedestrian deadline concept to report the user's trajectory information in the room. The information is available for care or caregivers to estimate the possible causes of falls. Our test results should be The design method can effectively detect the fall detection and reproduce the accident.
