以照片為素材之系統佈景主題設計之研究

由於數位相機的發展以及數位資訊的儲存技術迅速提昇，現今人們所拍攝及儲存的數位相片越來越多。然而，雖然有如此大量又珍貴的數位相片資源在手上，人們卻只有相對限縮的時間可以將照片開啟來好好瀏覽與回憶，更枉論其他好的方式來對數位相片資源再利用。在這篇論文中，我們提出了新的設計概念：Thememory，以解決上述兩點問題。Thememory字根來自於回憶（Memory）和桌面系統的佈景主題（Theme），指利用使用者手中握有的數位相片資源為素材，美化個人電腦桌面系統的佈景主題。藉此讓使用者可以在使用個人電腦工作之餘，可以便利地欣賞大量的照片，如此將回憶與佈景主題結合（Theme with Memory）。　　系統設計分為前處理與使用兩部份。前處理時我們分析使用者擁有的數位相片，從中擷取出有趣區域（Region Of Interest，簡稱ROI）；上線部份，我們根據專業設計師設計的佈景主題樣板（Templates），將分析出的ROI經過處理後顯示在樣板中，成為利用相片為素材的系統佈景主題。　　傳統上瀏覽照片，必須特意開啟相片瀏覽器，並安排一段特定的時間瀏覽。Thememory利用使用者片斷的時間以及桌面系統上零碎的空間來展示照片，使這些珍貴的照片得以重複使用。讓使用者在操作電腦時，可以環繞在回憶包圍之中。並且，我們提出不同的系統互動方式，幫助使用者回憶不同照片背後的故事，同時提昇使用者體驗（User Experience）。

People take more and more digital photos nowadays due to the convenient digital cameras and rapidly growing storage devices. However, people have limited time to browse these tremendous amounts of photos and there is nearly no good ways to reuse them. We present a new concept, Thememory, in this paper. Thememory, refers to Theme With Memory, embeds the photos into the program themes by retrieving the region of interest, as known as ROIs, from the user's personal photos and synthesizing the themes to become a program theme. Unlike traditional photo browsers that the user has to intentionally arrange a specific time to browse the photos, Thememory utilized users' fragmented time and programs' fragmented space, and reuse the tremendous amount of photos in an implicit and efficient way, letting the users embraced by their precious memory while using their computers for doing something. To build this system, we recruit professional designers to design templates of different themes using photos as materials, and then extracted the design principles. Furthermore, we give the interaction features to help users recalling memory with a pleasing user experience.
