游泳運動一直受到許多人的喜愛，尤其到了夏季，許多家長會帶著小朋友到開放式游泳池進行游泳或戲水，而造成游泳池人滿為患的情況，每當有溺水事件發生時，救生員更是難以在第一時間發現並立即做出有效的營救措施，而往往導致悲劇的發生。如何在溺水事件發生的同時立即發現並進行通報，以減少重大傷亡事故的發生，是大家一直所關注的議題。而隨著現代人越來越重視自己的健康狀態，開始透過智慧型穿戴裝置與手機配對來監測平常的運動數據、睡眠品質與心率狀態等。目前已有研究者利用智慧手機，收集游泳時的手部運動能量，利用能量的門檻來判斷是否出現溺水狀態，但利用能量的方式很難準確的區別出溺水與其他游泳姿勢。因此本研究將透過智慧手錶所收集的運動能量，轉為頻譜並進行分析，在頻譜上可以更容易的尋找出溺水時的手部揮動特徵，並使用藍牙發送通知到救生員的智慧型手機，建立即時溺水通報系統。

Swimming has always been loved by many people, especially in the summer, many parents will take the children to the swimming pool to swim or play in the water, which will cause the swimming pool to be overcrowded. Whenever a drowning event occurs, it is difficult for lifeguards to find and take effective rescue measures in the first place, which often leads to tragedy. How to immediately discover and report at the same time as the drowning incident to reduce the occurrence of major casualties is an issue that everyone has been paying attention to. As modern people pay more and more attention to their health status, they begin to monitor normal sports data, sleep quality and heart rate status through pairing with smart wearable devices. At present, researchers have used smart phones to collect the energy of hand movement during swimming, and use the threshold of energy to judge whether there is a drowning state, but it is difficult to accurately distinguish between drowning and other swimming postures by means of energy. Therefore, this study will transform the kinetic energy collected by the smart watch into spectrum and analyze it. It is easier to find the hand waving characteristics of the drowning in the spectrum, and use Bluetooth to send notifications to the lifeguard's smart phone, the establishment of a real-time drowning notification system.
