    # GentleGrip AI — 長者羽球智慧拍柄握感系統 ### 一、發想動機 近期假日只要有空,我都會與家人一同打羽球,也觀察到越來越多長者積極參與運動以維持健康。羽球是長者常見的運動選擇之一,許多長者的球技甚至比我還要出色。不過,隨著年齡增長,反應速度與肌耐力會逐漸下降,運動傷害的風險也相對提高,因此仍需注意體力狀況,並適時調整握拍方式以降低受傷風險。基於此,我希望設計一款專為長者打造的羽球智慧拍柄握感系統,協助他們在享受運動的同時,也能更安全、更有效地保護身體。 ### 二、互動情境 當偵測到過度使用或異常變化時,會透過輕震提醒長輩適時休息,減少 運動傷害風險。所有紀錄會自動同步給家人,讓關心成為一種溫柔的陪伴,而非打擾。 * 自動啟動,無需操作:握住拍柄即開始感測 * 偵測握力與疲勞變化:AI判斷是否過度使用 * 輕微震動溫和提醒:幫助長輩適時休息 * 活動紀錄自動同步:讓家人安心了解健康狀況 ### 三、目標使用者描述 * 長者,喜歡羽球、社區活動、注重健康但對高科技設備,有排斥感環境社區羽球場、公園空地、學校體育館等地進行休閒運動 * 安全揮拍、避免過度疲勞 * 不需主動學習操作科技裝置 ### 四、主要功能說明 | 模組 | 功能 | 使用元件 | | ---- | ---- | -------- | | 動作感測|偵測揮拍動作|超音波感測器或紅外線距離感測器 | | 視覺回饋|根據偵測結果回饋使用者狀態|三色 LED+ 電阻 | |動作提示|額外反饋,如「太快」時旗子抬起|伺服馬達| |資料顯示|顯示揮拍次數|Arduino 串口輸出 或 Processing 畫面| |中央控制|處理感測邏輯、控制回饋|Arduino UNO+ 程式碼| ### 五、使用者互動流程 1. 啟動互動模式 → 使用者按下按鈕或靠近裝置,系統進入準備偵測狀態 (LED 綠燈亮起,表示待機中) 2.使用者揮拍靠近感測器區域 → 與一般打球前暖身動作類似,只需自然地揮拍即可 3.感測器偵測距離變化或揮拍頻率 → 系統即時分析動作幅度、頻率、強度 4.系統根據偵測結果判斷狀態: 揮拍 → 🟢 綠燈亮 🟡 黃燈亮 🔴 紅燈亮 + 馬達震動或旗子抬起 5.裝置提供即時回饋(燈光 / 馬達) → 讓長者立即感知目前狀況,知道是否該放鬆或繼續 6.電腦同步顯示互動數據(進階) → 顯示:揮拍次數、提醒需要休息 ### 六、使用材料 | 名稱 | 備註| | ---- | -------- |Arduino UNO|控制板 | |超音波感測器|HC-SR04| |LED+220Ω電阻| 搭建在麵包板上| |伺服馬達| SG90| |按鈕 + 下拉電阻(10kΩ)|啟動或模式切換| |麵包板 + 杜邦線|快速測試| | USB線 |Arduino 連接電腦供電| ### 七、專案特色 * 自然動作觸發互動 → 以「揮拍」這個日常動作為互動輸入,不需額外操作 * 即時物理回饋 → LED燈號與伺服馬達動作,視覺與動作雙重提示,簡單明瞭 * AI 輔助概念嵌入 → 藉由行為偵測與數據分類,讓AI潛在分析行為狀態而非直接對話 * 模組化設計,容易擴充 → 可依照需求擴充聲音、手機同步等功能 ### 八、 預期成果 * 使用行為改善 協助長者控制揮拍強度與頻率,降低運動風險 * 增加使用安全感 明確提示狀態,提升使用者安心程度 * 互動體驗溫度化 技術轉為潛在陪伴與引導 * 展示與教學價值高 簡單易懂、模組化的展示方式 * 可延伸產品原型,可朝運動輔具、復健輔助方向發展 ### 九、 總結 本專案以「日常運動中的人性輔助」為核心,結合現有的羽球拍與Arduino微控制器,打造一套不須對話、不須穿戴的非接觸式AI互動系統。透過自然的「揮拍動作」作為互動觸發點,讓AI的智慧分析與即時提示融入使用者的運動習慣中,不造成干擾,卻能實際提供幫助,適時提醒其運動狀態,有效避免過度使用或疲勞帶來的風險,也強化了使用安全與信任感。
