摘要


隨著平均年齡不斷的上升,高齡人口不斷的增加,台灣已成為高齡化國家。而老化是人一生中必經的過程,一旦衰老後,看似簡單的上下樓梯對老人而言都是種挑戰,存在著跌倒以及死亡的威脅。本研究透過改良現有四腳枴,減少高齡者在上下樓梯時發生跌倒的機率,並以壓力感應器對電動助行車進行改良。改良後的四腳枴分別對學生和老人進行測試,受測者表示改良後的四腳枴在上下樓梯時的穩定性及方便性比市售的四腳枴要高。學生測試的結果經SPSS統計分析後,與市售四腳枴其改善具有顯著差異,其中以底座可收合式四腳枴最為顯著。老人測試後的訪談,可調角度式四腳枴在上樓梯的表現較為出色,底座可收合式四腳枴在上下樓梯都讓老人滿意。 助行車的測試部分:把手處的三個壓力感應器可協助辨識使用者意圖。結果顯示,過半的受測者表示需大力壓感應器才有反應,助行車的操控對老人具有正向作用,且受測者對於整體操作感到滿意。

With the increase of elderly population, there is an increasing need for a walking aid in daily life. For elder people, there is a threat in falling induced injuries. Firstly, the observation and questionnaire were carried to collect possible problems of the commercial available single rod walker. There are four supporting bar in the base of walker to fulfill the need of stability. But while going up or down through stair, the width of four supporting bar is wider then stair. Two kinds of modify single rod walker design were proposed to improve this problem. Both the foldable stand and the walker with rectangle edge show positive feedback from the participants. By supervised of medical doctor, elder people also practice the proposed design, and results in high acceptance. Then we study utilized pressure sensors to control walking aid machine movement. The data from three pressure sensors are analyzed, and the pressure distribution is used to set the proper motor response to ease controlling the walking aid. Pilot study indicated the design reduced user’s workload and effort, which has a positive impact on users.
