摘要

隨著資通訊技術發展迅速且成熟，傳統服務模式需逐漸向智慧服務模式轉變。以往因高齡退休社區內傳統餐食健康服務中餐食服務者與住民間缺少資訊交換，產生住民餐食滿意度、營養師飲食健康照護程度成效低、廚師難控制食材準備量及機構餐廳營運成本等問題，各方問題不一，難以得到平衡與改善。本研究目的為設計一餐食健康管理系統架構，改善高齡退休社區內現行餐食服務中的問題。研究目標包括：1) 經由文獻探討與半結構式訪談，分析高齡退休社區餐食健康服務現況及使用者需求；2) 基於使用者經驗，進行系統功能模組分析與了解介面設計規範； 3) 設計以高齡退休社區為例的餐食健康管理系統架構暨使用者介面；4) 驗證該系統平台的使用性，討論在高齡退休社區內導入智慧餐食健康管理服務系統的可能性。本研究採用協作產品設計和開發與以使用者為中心環境的瀑布式方法，強調了使用者觀點對系統開發的重要性。依循系統設計和開發的流程，採用半結構式訪談，蒐集住民與利害關係人的需求。訪談記錄透過ATLAS.ti 9編碼進行內容分析，透過角色法建立使用者行為模式的原型，再以情境故事法敘述系統應用場景。在系統介面原型測試與實驗前測之後，招募8位養生文化村住民作為受測者，利用系統原型操作任務完成與同步式放聲思考法，以使用者互動經驗作為意見回饋，再以SUS使用性量表進行使用性評估。SUS分數為71.56±13.49滿足使用性標準，而在原型操作中仍存在問題，整體表現為系統功能整合較好，對高齡住民而言易學習性較差。透過高齡者餐食健康服務滿意度問卷並進行系統使用前後測驗證餐食滿意度改善情況，平均分數由2.97±0.27提升至3.53±0.42。由於系統處於原型階段，未能在導入使用後進行後測，可能會影響滿意度結果。主要貢獻為建立一智慧餐食健康管理系統服務系統嘗試協助營養師、餐廳與機構進行餐食健康服務工作，以及提高高齡者餐食滿意度及飲食健康照護程度。

With the rapid and mature development of information and communication technologies, the traditional service model needs to be gradually transformed into a smart service model. In the past, due to retirement community traditional meal health service is a lack of information exchange between catering service providers and residents, producing residents’ meal satisfaction, dieticians’ diet health care is ineffective, it is difficult for chefs to control the amount of ingredients prepared and the operating costs of institutional restaurants. The parties have different issues, it is difficult to balance and improve. The purpose of this research is to design a meal health management system architecture to improve the existing meal service problems in senior residential communities. The research objectives include: 1) Through literature review and semi-structured interviews, to analyze the current status user needs of meal health management in senior residential communities; 2) Analysis system function modules based on user experience and understand interface design specifications; 3) Design a meal health management system architecture and user interface based on senior residential communities; 4) Verify the usability of the system platform and discuss the possibility of introducing smart meal health management service models in senior residential communities. This research adopts a collaborative product design and development and a waterfall approach a user-centric environment, emphasizing the importance of user’s perspectives to system development. Follow the process of system design and development and adopt semi-structured interviews to collect the needs of residents and stakeholders. The interview records are analyzed through ATLAS.ti 9 coding, the prototype of the user's behavior model is established through the Persona method, and the system application scenario is described by the situational story method. After the system interface prototype test and the pre-experiment test, eight residents of the Chang Gung Health and Cultural Village were recruited as testees, using the system prototype operation task completion and synchronous voice thinking method, using user interaction experience as feedback, and then using SUS usability scale to evaluate for usability. The SUS score of 71.56±13.49 satisfies the usability standard, but there are still problems in the prototype operation. The overall performance is that the system function integration is better, and the learnability for the elderly residents is poor. Through the elderly’s meal health service satisfaction questionnaire before and after system use. For improvement, the average score increased from 2.97±0.27 to 3.53±0.42. Since the system is in the prototype stage, the failure to perform post-test after introduction and use may affect the satisfaction results. The main contribution is the establishment of a smart meal health management system service model to try to assist dietitians, restaurants and institutions in meal health service work, and to improve the meal satisfaction of the elderly and the level of diet health care.
