目前市面上所販售的各式削皮器中，造型、材質十分多元，但由於產品語意的表達尚不夠明確，導致使用者在使用削皮器時，易產生各種姿勢。本研究改進市售中的一款削皮器，探討使用者對於暗示性使用方式的接受程度，並找出使用時的最舒適尺寸。本研究隨機抽查12位使用者的使用方式，經由統計及比較分析後，擬定反向為研究方向。利用人因操作實驗模式探討使用削皮器時相關的4項人體計測項目，將所得之數據與產品語意結合，設計出一款改良後之削皮器並統一使用模式做再一次的調查。最後利用問卷的方式了解使用者的滿意度，再經統計、T檢定，進而確認設計是否符合預期。由研究結果得知，於外觀增添暗示性的符號或特徵，進而引導使用者依照產品原本應有的方式使用，在運用產品語意與操作行為模式來設計與改善削皮器產品的設計是可被接受的。此外，反向握持使用削皮器時，大拇指距離刀刃8cm，大拇指與食指的握持夾角為80度的情況下，為最佳握持位置。

There are various kinds of peelers on the market. However, due to the unclearness of Product Semantics, it leads to diverse gesture of subjects. This study improved one of the peelers on the market. This improvement analyzed subjects' acceptance of implication manner and found out the most comfortable proportion (size of the peeler). At the beginning of the research, picked 12 subjects randomly and observe subjects' holding methods. After a series of statistical analysis and comparison, aim the research on the downward holding method. Next, picked another 12 peeler subjects randomly and record 4 different set of body measurement while using the peeler, then combine the data and the product semantic to improve the design of the peeler. Finally, through Statistical analysis and T-test to confirm the outcome (new improved design of the peeler) fits subjects' expectation.When the implicative sign or traits on the appearance of products are added, it would lead subjects to use the product in the original (correct) manner. This kind of improvement by Product Semantics is acceptable. The result showed the best holding position of the peeler have to fit the following conditions. 1. The holding position of the peeler has to be downward holding. 2. The distance between the thumb and the blade of the peeler has to be 8 cm. 3. The angle of the thumb and index finger while holding the peeler has to be 80 degrees.
