生活於手機相機普及的今日，人們逐漸依賴隨手可得的行動裝置記錄生活，影像記錄儼然成為今日人們記錄生活的方式之一。本研究致力於提供使用者個人化之飲食管理系統，讓使用者在利用影像記錄飲食之時，改變自身的多樣性飲食攝取行為，讓個體更為健康。透過健康控制與社會認知理論，我們以影像後設資料的運用，增加自我效能，提供使用者方便的飲食記錄方式、以及更能掌握自身的營養狀況，讓使用者在記錄飲食的同時，還能改變自身飲食攝取行為，更能作為未來回憶飲食狀況之線索。在實驗設計上，我們邀請6位受試者使用本研究所開發的飲食管理系統，利用兩週的時間真實模擬生活中的飲食記錄環境。我們分析使用者實驗前後的自我效能問卷，以及所記錄的飲食記錄作為評估依據。實驗結果顯示，我們的系統能夠提升個體自我效能外，還能夠改變個體的飲食攝取行為。因此本研究有效促進自我效能感協助使用者在記錄生活，讓個體飲食更加健康 / In these days, as the popularity of smart phone grows, people tend to rely on mobile devices to record their lives. Digital photograph has become one of the ways people recording their daily lives. This research is aimed at providing users with personalized dietary management system, allowing users not only use photos to record their life, but also change their behavior to keep users in good health. Based on health control and social cognitive theory, this application utilizes the metadata of the images to enhance self-efficacy, to provide users an easier way to record their dietary and take better control of their own health. Furthermore, the data of the application allows users to recall the dietary and thus improves users’ dietary habits. For the experimental design, 6 subjects were invited to use rthis dietary management application, to record their daily dietary in two weeks.
