Abstract:	本研究透過實驗確立目前市售手控立扇的操作缺點及改進空間。利用人因工程論點再設計，包含人體計測、人體能力限制、實驗結果及現有產品分析導入腳控立扇設計，利用電腦輔助設計與快速成型(RP, Rapid Prototyping)發展出踩踏式、腳踢式、滑桿式與旋鈕式四種原型。以人因效用評價實驗比較研究所設計之四種原型、現有腳控立扇與手控立扇在受測者操作上的表現。並取得23位男性與27位女性受測者在實驗中的主觀評價、操作時間、失誤次數及樣本滿意度排序，實驗結果使用SPSS統計軟體之多變量變異數分析進行探討。　　　　結果發現踩踏式原型立扇有最高的主觀評價、現有手控立扇最低；踩踏式原型立扇操作時間花費最短、現有腳控立扇操作時間最長；踩踏式原型立扇失誤次數最少、現有手控立扇則最多。受測者對於踩踏式原型立扇在各方面的評價與滿意度皆為最好；現有手控立扇除操作時間優於現有腳控立扇外，皆為最差。最後，研究成功透過人因觀點設計出符合用腳操控之立扇，但皆處原型階段，在材質、機構、外觀與操作回饋等還有設計之空間。研究成果亦可提供往後研究或設計之參考。　　This study found out the faults of operation and made improvements on the hand-controlled electric fan through pre-experiments. Ergonomics-based redesign of foot-controlled electric fans contains anthropometry, human ability and the result of per-experiment. Through the tools of computer aided design (CAD) and rapid prototyping (RP), four kinds of foot-controlled prototypes, i.e. button-treading, button-kicking, sliding-bar and turning-knob, were developed. Four prototypes (developed in this research) and two existing products (one hand-controlled type and one foot-controlled type) by ergonomic evaluation experiments. The subjects (23 males and 27 females) were asked to perform ergonomic evaluation experiment on the six samples. Subjective evaluation, operation time, loss times and satisfaction degree were shown and discussed by using SPSS software.　　　　The results revealed that type of button-tread got highest subjective evaluation and the existing hand-controlled type received the lowest scores. Regarding the operation time, button-tread type took the shortest time and the existing foot-controlled type is the worst. Regarding the loss times, button-tread type was the best (fewest losses) and hand-controlled type was the worst. Totally, button-tread type was mostly best on evaluations and satisfaction degree. The existing hand-controlled type was worse than the foot-controlled one except the item of operation time. 　　　　Final, a foot-controlled electric fan was successfully developed in this research through ergonomics viewpoints. Although the prototypes were not perfect, future studies and advances are still required on the aspects of material, mechanisms, appearances and operation feedback.
