Projection & Figure–Ground投影與圖地反轉
This master’s research investigated how projection methods could support a more systematic process for creating figure–ground illusions in graphic design.
Because figure–ground images often depend heavily on individual experience and intuition, the study examined relationships between silhouette, positive and negative space, metaphor and projection. Front projection, rear projection and photogram-based approaches were explored, with rear projection combined with mind mapping identified as the most feasible method within the study.
The research developed a ten-step design process: defining a theme, breaking it down, developing associations, returning to source objects, considering metaphor, selecting appropriate forms, anticipating the image, projecting, observing and post-processing.
The method was applied to ten Sustainable Development Goal themes, producing fifteen posters, and was subsequently tested through a workshop in which participants produced eleven additional works. Post-workshop responses indicated improved understanding of the method, greater ability to apply it, and strong motivation to continue experimenting with figure–ground illusion. The study demonstrates how an intuitive visual technique can be investigated through an explicit and repeatable design process.
這項碩士研究探討投影方法如何讓平面設計中的「圖地反轉」創作，成為更有系統的流程。
圖地反轉的圖像往往高度依賴個人經驗與直覺，因此研究檢視了剪影、正負空間、隱喻與投影之間的關係。研究比較了前投影、背投影與實物投影（photogram）等方式，發現「背投影搭配心智圖」是研究範圍內最可行的方法。
研究發展出十個步驟的設計流程：定義主題、拆解主題、發展聯想、回到原始物件、思考隱喻、選擇合適形體、預想畫面、投影、觀察，以及後製。
這套方法應用於十個聯合國永續發展目標主題，產出十五張海報；之後再透過工作坊測試，參與者另外完成十一件作品。工作坊後的回饋顯示，參與者對方法的理解與應用能力都有提升，也有很強的意願繼續實驗圖地反轉。研究證明，一種仰賴直覺的視覺技巧，也能透過明確、可重複的設計流程來研究。
Making with projection透過投影製作圖像
The research tests how objects, bodies and projected light can produce figure–ground images. Workshop participants adjust physical forms and observe the silhouettes they create, moving between an object and the image around it.研究測試物件、身體與投影光線如何產生圖地反轉圖像。工作坊參與者調整實際形體，觀察投出的剪影，在物件與周圍形成的圖像之間來回確認。

Reading the space between閱讀形體之間的空間
The illuminated panels place several figure–ground results side by side. Each image asks the viewer to shift attention between the dark silhouette and the light space it defines.發光面板將多件圖地反轉成果並列。觀看時，注意力在深色剪影與它所界定的亮部之間切換，讀出不同的形象。
Recording a repeatable process記錄可重複操作的流程
The publication records the relationship between the setup, projected image and finished graphic. These stages sit within a ten-step method developed to make figure–ground experiments easier to plan, observe and repeat.書籍記錄實驗配置、投影影像與完成圖像之間的關係。這些階段被納入十步驟的方法，讓圖地反轉實驗更容易規劃、觀察與重複操作。
