近年來，蓬勃的設計活動伴隨著不同的設計方法應用於產業中，但是，創新的產品卻無法獲得足夠有效的設計資源，藉以提供設計創作者作為設計概念發展上的依據，設計者在發展概念的前期階段，可以從各種經驗、直覺或探索等等的設計方法中獲得幫助，藉以發展出整體性的設計概念，但在設計過程中，如果出現無法透過各種設計方法進行設計抉擇的情況發生時，為使其得以繼續進行，設計者必須以“猜測”的方式，亦即「先行感知」的方式進行，本研究稱之為設計者的“推測模式”，然而，我們終究不清楚“預知”在整個設計過程中所代表的意義以及產生的影響為何？為釐清此獨特之行為模式，本研究藉由實驗設計一的猜猜看遊戲（共四組實驗活動）去探索「推測模式」的發生，以瞭解設計者在「預知」上的特徵，並說明「預知」在設計發展中的概念及定義。

另一方面，為求進一步瞭解「預知」實際對未知設計事件的影響，透過實驗設計二進行以「未來」為主題的創意發想活動（共兩組實驗活動），本研究將各組創意發想的結果，藉由，水平發展的創意數量及垂直發展的概念組合進行交叉比對與實驗後的問卷調查分析，證實「預知」對設計團隊及跨領域團隊的影響，最後，將實驗活動四（先進行撲克牌遊戲猜猜看或大老二之後再依獲勝順序搭配自己選牌或隨機抽牌之創意發想活動）之AC、AD、BC、BD四組中，包含創意想法及設計草圖的設計概念，以隨機取樣的方式交由第三方針對設計概念之關聯性、表達性、想像性、創新性、可行性此五項創新產品的要素進行評量，再次驗證「預知」有效地提供了設計者在面對未知的設計事件所需的資源與幫助。

同時，本研究的結論亦對於互動設計、腦力激盪與牌卡運用有相當的助益；最後，藉由本研究所提出之設計的「推測模式」特徵，提供兼具量化、統計、質性、歸納等特性的評量工具與方法，有助於設計者面對實務上未知的設計挑戰。

In recent years, many design activities with diverse design methods are applied to industry, but innovative product design has never been able to get a valid resource. In the starting phase of developing a product, the designer can get help from experience, intuition or explorative design methods, etc., and develop a holistic design concept. However, in the design process with too many uncertainties, a designer usually uses a "guess" approach, that is, "first hunch" foresight; in this study we call design "speculative mode". However, we do not know what the meaning and the influence of precognition in the design process are. In order to understand this unique behavior patterns, the study looked at the game to explore the occurrence of "speculative mode" through the experiment (four groups) of guess, the unpredictable behavior through an understanding of the characteristics of the designer to explore the designer "precognition" of impact, and explain how "precognition" is defined in the design concept and development.

On the other hand, in order to further understand the impact of unknown design event "precognition", we conducted "Future" as the theme of creative thinking activities through two experiments (two sets of experiments). In this study, the results of creative thinking are measured with horizontal grounding and vertical grounding, questionnaire analysis, and comparisons between the experiments, to understand how speculative behavior influences the design team and the interdisciplinary team. Finally, the design concepts including creative ideas and design sketches from the four sets of experiments (AC, AD, BC, BD four groups) are randomly sampled for a third party assessment, encompassing relevance for the design concept, expressiveness, imagination, creativity, feasibility. Once again the result indicates that "precognition" effectively provides resources for designers in the event full of the unknown.

 
At the same time, the conclusion of this study contributes to creative development and application in the field of interaction design, brainstorming and card sorting. Finally, through discussing the "speculative mode", we provide quantitative, statistical, qualitative and inductive methods and tools, which help designers face the unknown design challenges in practice.
