導入承擔性與知覺訊息對應關係於血糖試片設計

Introducing the Affordance-Perceptual Information Relation in the Design of Blood Glucose Test Strips

為了減少設計者與使用者之間溝通落差的問題，並減輕使用者在操作上的負擔，產品設計的趨勢朝向直覺性操作方式發展。產品本身如果擁有自我說明的能力，使用者便能藉由產品本身的設計特徵，了解產品的功能與操作方式。然而由於高齡族群的行為與認知能力逐步退化或喪失，在與產品互動的過程中，難以快速地感知產品所傳達的承擔性，達到直覺使用的目的。因此，本研究由承擔性與知覺訊息的概念出發，針對高齡族群使用血糖試片的簡單任務進行探討。首先針對使用者在操作血糖試片過程所發生的可用性問題提出設計構想；接著導入承擔性與知覺訊息對應關係檢核設計構想，透過迭代設計的過程提出兩款新試片。最後可用性測試的結果證實，新試片的操作時間優於市售試片。本研究所獲得貢獻如下：1.導入檢核承擔性與知覺訊息對應關係所提出的設計成果，充分呈現可感知承擔性，有助於高齡者完成簡單任務；2.在設計階段導入檢核承擔性與知覺訊息對應關係的方法時，配合迭代設計的過程，較易達到可感知承擔性的效果；3.進行簡單任務特性的產品設計時，應確認操作順序並加強物理承擔性的應用，可避免導致使用者操作錯誤；4.進行小尺寸產品或部件設計時，應對實際的使用情境、操作任務的順序與細節進行分析，並以較容易被感知的物理承擔性為主。最後，期望研究成果有助於未來應用承擔性與知覺訊息於實務產品設計時之參考。

To reduce the communication gap between designers and users, and reduce the burden on users in operation, the trend of product design is developing towards an intuitive operation. If the product could explain itself, users can understand the function and operation behavior of the product through the features of the product. However, the behavior and cognitive ability of the elderly are gradually degraded. In the process of interacting with the product, it is difficult to quickly perceive the affordance by the product and achieve the purpose of intuitive use. Therefore, from the concept of affordance and perceptual information, this study explores the simple task of using blood glucose test strips in the elderly. Firstly, design concepts of blood glucose test strips were proposed form the usability problems during the operation process, then the affordance-perceptual information relation was introduced to check the design concept repeatedly. Two new strips were proposed through an iterative design process. The results of the usability test confirmed that the operating performance of the new strips are better than most of the commercially available ones. The contribution of this study are as follows: (1) The design results proposed by Introducing the affordance-perceptual information relation can fully present perceptible affordance and assist the elderly to complete simple tasks; (2) Introducing the method of checking the affordance-perceptual information relation in the iterative design process, it is easier to achieve the effect of perceptible affordance; (3) When designing products with simple task characteristics, the operation sequence should be confirmed and the application of physical affordance should be strengthened to avoid user operation errors; (4) When designing small-sized product or component, the actual using situation, the sequence, and details of operation tasks should be analyzed. It is expected that the achievement will be helpful for future reference in the design of practical products using affordance-perceptual information relation.
