醫療網站包含醫療術語、病症、療程以及許多種類的醫療知識。對於一般大眾來說，若醫療網站的內容以純文字呈現將導致難以閱讀及理解。本研究探討在網路醫療知識中對一般大眾合適之呈現方法，以及，不同的呈現方法將如何影響閱讀習慣。本研究整合了相關醫療知識呈現之研究結果，設計出醫療知識呈現之設計準則，並且運用知識本體論之分類方法當作醫療網站之架構，以建立適合一般大眾之醫療知識網站。為了驗證本研究之設計，過程中招募三十二名人員，並且透過問卷、紙筆測驗、訪談以及眼動儀收集資料。透過了解參與者在不同呈現方法之眼動行為、測驗之進步幅度以及問卷內容，將能夠讓我們了解一般大眾在不同呈現方法下之閱讀行為、學習能力以及使用性。

Text-based medical website which includes medical terms, diseases, treatments, and many types of medical knowledge leads to hard reading and low comprehension for general public. This study investigates the appropriate representations of online medical knowledge for general public and the different representations effect on human reading behavior. We integrated several researches’ results on the representations of medical knowledge as the design guideline and utilized an ontology-based classification as the website architecture to investigate how to present medical knowledge to general public. To verify our design, thirty-two participants were recruited for this study, and multiple methods were employed to collect data, including questionnaires, pencil and paper tests, interview, and eye tracking analysis. Eliciting participants’ viewing behaviors and test recall rate benefit us understanding the reading behavior, learnability and usability of various users on different kinds of medical websites.
