互動式觸控展示系統之設計

電腦輸入設備由大型機械式操作演化至使用鍵盤滑鼠輸入，近期則進展到以觸控式螢幕為主，因為輸入方式改變，使得軟體介面也開始演進，從早期終端機畫面，到色彩豐富的視窗介面以及動畫形態的操作介面，這些介面設計讓人機互動更加緊密，因此，該如何設計軟體介面才可讓觸控螢幕技術發揮到最大人機互動效果，是目前非常值得探討的研究領域。公眾場合使用的觸控螢幕系統，在既有人機互動的情況下，會希望達到多人互動效果，本論文提出的互動式展示系統，結合投影機與觸控設備，不僅可讓使用者隨心所欲地欣賞喜歡的照片，更可利用藍芽無線通訊上傳手持裝置內照片到系統畫面，與更多人分享，使之成為在展示場合內的資訊分享與交換中心。當觸控螢幕上的照片逐步增加會造成系統畫面變得雜亂，讓觸控操作失去了原有的便利性，故本論文設計之互動推薦機制，可記錄每位使用者的瀏覽資料，並利用關聯法則找出資料的關聯性，系統藉由關聯結果主動推薦使用者可能喜愛的圖片。而針對在大型螢幕上的觸控操作，會因為操作範圍較廣而變得麻煩，為解決這樣的問題，系統會記錄使用者的點擊與拖曳習慣，透過關聯法則找出習慣操作區域間的關聯性，將此關聯結果與互動推薦機制搭配，把使用者可能喜愛的圖片分配在習慣操作路徑上，以符合使用者的操作習慣。最後，我們透過問卷調查來了解使用者操作本論文設計的展示系統心得，64%的使用者認為觸控式展示系統能夠吸引他們使用，74%的使用者認為本論文設計的互動推薦機制能夠在大量圖片中找到他們想要觀賞的圖片，而有71%的使用者喜愛以資訊分享交換中心與觸控式螢幕設計的展示系統。

Computer input device was developed from the large-scale mechanical operation to keyboard and mouse. Recently, touch screen technologies are major trends in input device domain. Software interface also begins to evolve on account of convenient input technologies. From console mode to colorful window’s interface and full of animation interface, they make close interaction between human and computer. The display system not only focuses on human-computer interaction but also achieves widespread multi-people interaction on the public place. Therefore, this thesis proposes an interactive display system which combines a projector and a suite of touching equipment. Users have their way to enjoy favorite pictures or share pictures with others by using handheld device’s Bluetooth to upload data. This touch system can be a center for sharing and exchanging information. This interface will lose it convenience while the volume of pictures increases. An interactive recommendation mechanism is proposed to recommend interesting pictures to users. It is inconvenient in touching a large-scale screen. To solve this problem, our system discovers association rules extracted from users’ click and drag actions. Association rules are used to allocate interesting objects along the fingers’ moving route. In this way, pictures are distributed over the screen according to users’ operating habit. Finally, we have a sample questionnaire for analyzing users’ satisfaction. 64% of the people feel the touch display system could attract their attention. 74% of the people consider the recommendation function helps them to find favorite pictures. And 71% of the people enjoy this touch display system.
