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.
