電子病歷的發展與醫療資訊發展的共同的目標，隨著人口老化，醫療需求量大幅增加，各種醫療系統、軟體的建置複雜且多樣，增加資訊統一的困難，因此需要資訊交換標準。近年來多媒體技術的進步，在圖文介面方面無論是電子筆、互動式顯示器、加載觸控功能之作業系統，新科技的輸入介面功能都朝向手寫及手繪發展的趨勢。本研究探討Windows 7作業系統環境的觸控功能，以手繪取代滑鼠，建置醫療圖像手繪圖功能的環境，並且以符合健康資訊交換第七層協定協會（HL7）制定的臨床文件交換（CDA）標準，連結手繪的圖檔，將結果以多媒體電子病歷表單的方式呈現，完成一套符合CDA標準及繪圖功能的醫囑輸入系統，可以更方便和更有效率的解決圖文醫囑輸入上的問題加強醫院資訊系統功能。

Electronic medical-record promotion is an important goal for medical informatics development. The aging of population accelerates the medical needs dramatically. Because of the complexity and diversity in the integration of the medical-information systems, following the established standards is becoming necessary. In recent years, the multimedia technologies, such as the graphic interfaces, digital pens, interactive monitors, and touch panel operating systems, are progressing quickly with the input interface developed toward handwriting and drawing. In this study, we investigated the touch functions installed a touch-screen compute under the Windows 7 operating system. The purpose of this investigation is to replace the mouse with handwriting and drawing to create a user-friendly graphic input environment for medical records. We also apply the standard format of the Clinical Document Architecture (CDA) developed by the Health Level Seven (HL7) organization to link the drawn graphic files and present them in the multimedia medical record forms. The system will effectively and efficiently solve difficulties in the graphic data input for a physician order and improve the diverse functions of hospital information system.
