過去，感知物件的互動方式大多發展於大型互動桌上，其技術主要是採用影像辨識來進行互動偵測，隨著平板的普及，我們希望能將大型互動桌的實體互動體驗帶到平板世界，然而現今平板使用之電容式觸控技術有別於大型互動桌之影像偵測技術，無法直接應用影像式的物件辨識方法，因此設計出一套結合平板電腦與感知物件的開發工具，目的是要讓互動設計的開發者能夠快速開發感知物件的互動模式。 而電容式實體互動物件設計較為複雜，對於互動設計的開發者而言，要去製作、開發這些互動物件不論是在電路或是實體物件都是有一定的難度，並不是所有的開發者都擁有相關的背景或是資源。而為了讓原型製作更加的簡單在軟體上我們設計了一套SDK，在硬體上結合了樂高積木和導電的膠帶，不僅製作快速、成本低，在組裝上也能擁有一致的規格以減少誤差的發生。藉由其底座組合方式的差異也就代表著不同的感知物件。因此開發者只需套用我們所設計的SDK就可以將原有的作品加上實體互動物件的互動模式。 / The Tangible User Interface (TUI) has been widely adopted on interactive tabletops by using optical sensing techniques and fiducial markers. With the huge growth of smartphone and tablet market, we hope to expand the tangible interaction experience to the off-the-shelf touch devices. However, most touch devices use capacitive sensing techniques that can only detect human fingers. We create a tangible hardware toolkit base on capacitive touch devices so developers can use it to build tangible interactions in a fast way. We put conductive adhesive tape on LEGO blocks to form an identifiable footprint. The footprint could be attached onto a tangible object. And the pattern of the footprint could be easily arranged to represent different identities. We also provide a flash SDK that can be quickly integrated into a developer’s project and then enable tangible interactions. We expect our hardware toolkit and software SDK can benefit more developers to create tangible UI applications on the capacitive touch devices.
