糖尿病是一種慢性疾病，在糖尿病防治與照護管理之中，除了需長期的配合醫院的診斷指示服藥或施打胰島素來控制血糖，糖尿病病患者本身還必須持續自我的定時血糖監測，進行飲食控制、適當的運動等管理行為，以達到減少糖尿病併發症發生的風險，所以想要維持良好的血糖控制，對糖尿病患者而言是長期性的挑戰目標。
本研究目的是以使用者經驗為研究核心，透過三個階段設計APP。第一階段的使用者經驗研究是透過觀察與半結構訪談，來發掘糖尿病患者的需求與問題，並評估現有三款血糖紀錄APP優缺點，作為第二階段之設計參考；在第二階段使用者經驗設計中，將提出設計解決方案與實際APP製作；第三階段的使用者經驗測試，以質性訪談與量化問卷共同進行實驗，藉此深入探討糖尿病患者使用APP前後之經驗差異性。本研究運用手機應用程式作為設計媒介，針對糖尿病患族群設計符合自我健康管理的APP。其研究目標為：(1)了解糖尿病患自我血糖控制管理之需求；(2)設計App介面架構與功能；(3)透過使用者測試，探討APP其使用性與使用者經驗；(4)歸納結果，並提出修正和未來建議。
從使用者經驗研究階段得知糖尿病患者不僅需要血糖的監測，還需要額外的健康管理，其中又以飲食為最直接影響血糖起伏的原因，所以針對飲食控制與血糖的紀錄需求，設計出「糖尿病飲食日誌」APP。最後，在使用者經驗測試研究結果顯示：(1)本APP可以幫助糖尿病患者學習與檢視飲食和血糖的關係；(2)使用本APP比紙本記錄更清楚與便利，且方便即時紀錄、回顧與分析數據；(3)以飲食記錄結合地圖定位的功能，可連結糖尿病與實際飲食的經驗與建立個人飲食地圖資料庫；(4)糖尿病飲食記錄加入社群的設計，未來仍須進一步考量心理層面和互動設計之關係。藉由本研究之過程與結果，期許作為日後欲開發糖尿病飲食相關設計者之使用者經驗設計參考。

Diabetes is a chronic disease. For diabetes prevention and long-term care management, it requires anti-diabetic medications or use insulin to control blood sugar according to doctor’s diagnosis. Moreover, to further reduce the risk of complications commonly induced by diabetes, it is necessary for patients to self-monitor their blood glucose regularly, keep diet control, and exercise appropriately, among other preventative. Hence, it is a long-term challenge for diabetes patients to keep blood sugar under-controlled.

This study designed a mobile application of health management for diabetes patients. To present the development of the APP with three stages, the first stage was user experience research, which identified diabetes patients’ needs and problems through observation and semi-structured interviews, and evaluated three diabetes applications’ pros and cons to be the reference of the design specifications. The Second stage, user experience design, discussed the procedure of designing the APP based on the users’ experience. The third stage, user experience test, explored the differences of user experience before and after using the APP by interview and experimental questionnaire. The objectives of this study were fourfold. First, to understand the needs of diabetes self-management with glycemic control. Second, to design and build the APP interface and function. Third, to evaluate the APP’s usability and user experience testing. Fourth, to analyze the results and propose modification and suggestion.

The user experience research showed that diabetes patients need not only the self-monitoring of blood glucose but also more health management. It was also identified that diet as the most important factor directly affected the glucose levels. Base on these findings, this study designed an APP named “Diabetes diet diary.“ The user experience testing results showed that: (1) The APP could help diabetes patients to learn the relationship between their diet and blood sugar. (2) The APP could help the users to record their diet instantly. It also provided a more convenient interface for review and analysis of the data than paper records. (3) By combining diet record and information on users’ location, this APP linked the blood sugar level and eating behavior and constructed customized personal diet maps. (4) By adding the concept of user community, it provided the possibility to explore how the design might further improve patients’ psychological wellbeing. This study could also contribute to the designs that are associated with diabetes prevention and control.
