近年來，無所不在的運算(ubiquitous computing)的概念逐漸地被廣泛應用於各個領域。為了改善人類的生活中的便利性與娛樂性，而智慧家庭是應用此一技術廣泛運用在生活中的代表。在智慧家庭的環境下，本研究開發一個利用圖形碼來操作實體介面的新型操作方式。在本研究中利用焦點團體法萃取圖形設計的元素進行設計開發圖形碼。而圖形碼不僅要能被程式辨識，而且還要可以向使用者傳達其提示操作的含意。在評估階段，程式辨識率的測試與主觀評價問卷分別進行，以此來評估本研究提出之圖形碼在實體操作介面中實行的可能。演算法測試結果得知圖形碼可以順利被演算法辨識。主觀評價的結果得知圖形可以成功地向使用者傳達其提示的內容和語意。最後本研究的結論提出圖形碼設計是符合電腦視覺與使用者認知的。在未來發展上，圖形碼可以廣泛地附加於家中物品之上執行操作，透過辨識系統辨識，可以與智慧家庭系統進行互動，藉此達成創新的物件辨識系統。

Recently, the concept of ubiquitous computing gradually becomes applied on wide range of field. In order to improve convenience and entertainment in human lives, a smart home system is a representation that is widely used in family life. In this study, we invented a new operation which aims to use pattern code to interact with tangible user interface. In this study we conduct a focus group to extract pattern elements to design to derive the pattern code designs. The new patterns codes not only can be recognized effectively by algorithms but also provide the feedforward to convey the operational information to users. For evaluating the feasibility of pattern code design, the questionnaire of subjective perception and the testing of recognition rate were conducted respectively. The result of testing showed pattern code can be recognized well by algorithm. The result of subjective perception indicated pattern code can success to convey their feedforward and semantics to users. Finally we can conclude the pattern codes of recognition can be utilized in TUIs and verify the new pattern code designs conform computer vision and human perception. In the future, we can apply this systematic pattern code diversely in the interactive process of smart homes as a key to detect objects to achieve the object recognition system innovation.
