本創作主要為基於習慣、記憶、生命記錄理念而開發的應用程式，希望以眾多的行動應用為基礎，藉由本創作主動提醒的機制，讓使用者更容易回想過去的記憶、再次體驗重遊的經驗和感受，並試圖了解使用者在經由提醒下的影響。 本創作為實作於iPhone上App，使用Objective-C程式語言撰寫，稱之為「iRemind」。實驗結果的三e指標、介面使用經驗皆有達到實驗所設定的目標，結果發現，大多受測者滿意本創作的設計與功能，也滿意本創作提出主動提醒的概念，認為有助於回憶事件，而且覺得是有趣的。但頻繁的提醒記憶會影響使用者在體驗過程的愉悅性，在主動提醒機制上，需要符合使用者需求進行相關設計，因此最後本文有提出幾項建議與設計作為參考。 / This research developed an application based on the concept of people’s habits, memories, and life-logs. We not only hoped that users can recall their memories or re-experience the feeling of their travels easily by the mechanism of active reminder, but also wanted to realize the effect on users. The system was implemented on iPhone, so we used Objective-c as primary language. And we named it “iRemind”. The “3-E indicators” of the experiment results and interface of user experience all achieved the desired goal. Most of users approved iRemind’s design, function and the concept of the active reminder, and they believe it also helps them recall past events. Besides, they think it’s interesting. But when it reminds too frequently, the enjoyment of user experience will be reduced. Therefore, the mechanism of active reminder design should consider users’ needs. In the end, we proposed some suggestions for future improvement.
