碩士 === 國立成功大學 === 工業設計學系碩博士班 === 94 === When entering or going out of a closed space, people take the actions of pushing and pulling a door. Such actions are common wrist movements in our ordinary life. However, people sometimes feel confused with the ambiguity between a door’s pushing and pulling in public space. Under the circumstances of emergency, a person’s intuition of operating a door even dominates the safety of his life. The purpose of my research is to explore the push-and-pull Affordance between an operator and an object, in terms of collecting ordinary objects which possess the functions of pushing and pulling. I intend to re-examine the design of a door on the aspect of its pushing and pulling functions in order to solve the problem of such push-and-pull ambiguity. Based on the way of discussion, my research begins with the study of encyclopedia from which I collect and make one hundred and twenty-two samples. Then, into three groups I classify these samples, which possess the properties of pushing and pulling Affordance: they are pushing group, pulling group, and group of push-and-pull ambiguity. After the classification, I interview people who participate in my research and collect their opinions of these three groups. Finally, by means of Quanptification I, I try to find the Affordance of pushing imagery, pulling imagery, and ambiguous imagery between the actions of pushing and pulling. And then highest Score of Categories would be solitarily added on a door for the operation. The research points out the following facts: 1.the properties of an object about affordance of pushing imagery , which are「plane surface」；the part of contact in proportion to「be smaller than palm of the hand」；the situation of the preceding actionable part is「the moving front contents」；and it is not affected by materials. 2.the properties of an object about affordance of pulling imagery , which are「the form of line」、「the form of ring」、「the form of mushroom」；the materials are「rope」、「paper」、「cotton」；the part of contact in proportion is「handful area」；the situation of the preceding actionable part is「the middle situation in revolved」. 3.the properties of an object about affordance ofmbiguous imagery between the actions of pushing and pulling , which are「the form of network」；the material is「glass」；the part of contact in proportion is「a drop of a finger」；the situation of the preceding actionable part is「the move of circular track 」. My intention is to provide a designer with a reference of a door’s push-and-pull function in order to solve the problem involved with the push-and-pull ambiguity.
