本論文的核心價值在於藉由雨傘握柄的再設計，討論產品中的感知承擔特質（Perceived Affordance）、感性工學（Kansei Engineering）與適用性（Usability）三者之間的關係。內容包含以Affordance與感性工學來分析現有產品以及相關產品，以量化問卷與實驗法探討消費者對雨傘握柄需求的方向，同時也可用於適用性檢測，以推論本研究之論點。本研究始於討論Affordance、感性工學與適用性，接續以Hybrid KE（混合感性工學系統）方法設計雨傘握柄，在研究中加入雨傘握柄的人因尺寸調查之後，於模型製作中特意加入感知承擔特質以提昇使用者對該樣本的使用感知，最後在適用性檢測階段加入兩個代表性的市售樣本觀察差異。 研究結果顯示出不論在現有產品或是設計中的產品，該產品的感知承擔特質、感性工學與適用性議題，皆有明顯程度之相關性，進而運用此產品建立出這三個議題之關係架構。 The core value of this study is to build up the relationship between Perceived Affordance、Kansei Engineering and Usability by the case of umbrella handlebars redesign. The content of this study contains analysis of existing products using affordance and Kansei Engineering, conferring the umbrella handlebars requirement of consumer by quantification questionnaire and experiment. This study starts at discussing the issues of Affordance、Kansei Engineering and Usability, then to redesign umbrella handlebars by Hybrid KE. After the then handlebar size studies, perceived affordance on the prototype producing is considered, finally in the usability test step, two existing products were also observed about the difference between the existence and redesigned ones. The result of this study reveals that the Perceived Affordance、Kansei Engineering and Usability issue of the existing and redesigned products are all significantly correlated. Thus, this study has constructed the relation correlated frame of these three issues .
