本研究主要的目的是以支應性理論探討於開放空間中「環境屬性」、「使用者特性」與「活動支應性」之間的關係。研究以「台灣國家美術館前開放空間」作為實證地點，對使用者進行問卷調查。
本研究結果顯示：「性別」與「行動能力」不同對「各項活動支應性感知」出現顯著差異，但對「總體支應性感知」未出現顯著差異；「年齡」、「活動偏好程度」、「活動目的」與「熟悉程度」不同則對於「總體支應性感知」與「各項活動支應性感知」皆出現顯著差異。研究結果發現，個體的身體與心理屬性，皆為影響其對環境中各種活動支應性感知的要素。且透過對個體屬性所對應之活動支應性的調查，能夠鑑別出不同族群在感知活動上的差異性與類型。

The major purpose of this study was to explore the relationships among variables of environmental attributes, users' characteristics, and activity affordance by affordance theory. Open spaces of National Taiwan Museum of Fine Arts served as a study area. Questionnaire survey method was adopted to generate the required data.
The results showed that gender, action ability had significant influences on every perceived activity affordance, but not for the overall perceived affordance. However, age, the degree of activity preferred, activity purpose, and the degree of familiarity had significant influences on both overall perceived affordance and every perceived activity affordance. The study concluded that users' physical and psychological attributes had significant influences on the perceived activity affordance in an environment. Through the survey of individual attributes corresponding to activity affordance, the study identified differences and types of perceived activity between different user's groups.
