摘要
智慧型手機普及後，許多人時時刻刻都低著頭使用手機，「低頭族」這個新名詞也因應而生。科技帶來便利，但亦帶來相對的負面影響，長期低頭使用智慧型手機可能造成肩頸負擔以及視覺疲勞。
本研究欲探討因使用智慧型手機而產生的疲勞感，藉由實驗設計的方法，針對不同的使用姿勢，分別包括站立與坐的姿勢、低頭使用手機角度以及手持手機角度，進行研究分析，並用田口方法計算疲勞感的具體數據，依照得到的數據，得出最佳姿勢組合。結果顯示：操作姿勢以坐姿使用、不低頭使用、手持角度適中時，身體所負荷之疲勞感最小，也就為最舒適使用姿勢，此結果可供智慧型手機使用者作為參考，希望能提高大眾使用智慧型手機時的舒適度。
關鍵字：低頭族、智慧型手機、使用姿勢、疲勞感。
