標識為多樣的場所和設施提供了有用的補充資訊。且可被視為空間的使用說明。將環境空間與相關的文字及圖形，以使用者中心的概念為出發點，用設計的方法，藉由標識向外延伸指引至環境空間；而環境空間的資訊則藉由標識內向傳達至人群。本創作報告係以資料蒐集為出發點，將國內、外文獻對於指標識別、標識以及資訊設計相關原則或概念等加以整理。並分析臺灣國際機場（桃園機場）的標識現況與探究國外機場的標示設計概念，以歸納及演繹的方法，提出一套適合臺灣國際機場需求的標識系統設計原則，且依據此一原則所操作標識系統的設計成果，將可協助改善臺灣機場目前的標識系統，朝向以使用者為中心概念的標識設計。而本報告之創作歷程，則可作為未來標識設計人員、後續研究人員之設計參考，並應用於其它類型公共空間的標識設計上。

Signage provides very useful supplement information for a variety of areas and facilities. Signage can be viewed as a guide in a specific location. It is crucial to incorporate the environmental space along with its related text and graphics in the design and such design should be based on the user-center as the guiding principal. As such the signage can be extended outward to the environment space and vice verse the environment space information can be extend inward back to human through signage. This report is based from the research of information collection as the starting point. It attempts to categorize and organize, the existing literatures which is available domestically and/or internationally, and the design principles and concepts in the areas of wayfinding, signage and information design. In addition, this paper also analyzed the existing signage design in Taiwan's International Airport (TPE Airport) and conducted studies in many designs from famous foreign international airports. Using the inductive and deductive methods, the author concluded the paper with a proposal in signage system design principles. As a result, such signage system design principles can be applied to improve the current signage system in Taiwan's International Airport toward a more user-centered environment. The design process presented in this paper may also be used as a reference for future signage system design and follow-up studies and be applied for design toward other types of public spaces and/or buildings.
