隨著市場電容式觸控技術已成為使用者和機器溝通的重要橋樑，其中回饋機制(Feedback mechanism)技術將更顯關鍵。本論文主要就是利用表面電容式觸控面板本身的特性，做為一個輸入及輸出的介面，搭配外部軟、硬體程式的控制，整合其它的周邊輔助電路，來設計: (1)輸入介面：心跳、體脂、身體質量指數(BMI)回饋式生理訊號量測電路系統；(2)輸出介面：電刺激器回饋式電路系統。為了提升便利性，系統設計上全面是採用數位控制電路調整，以低電流高解析度的繪圖型液晶顯示器作為顯示畫面，以手指做為媒介，針對各種狀況以人體實際測試，提供預防錯誤與危險的防呆機制，並利用此系統加以應用在雲端醫療暨居家照護產業技術上的發展。

In the market, surface capacitive touch panel technology has become an important communicating component at the user-to-machine interface and the feedback mechanism is indeed dominating in the system. The purpose of this work is to use the features of the surface capacitive touch panel to develop an user-friendly interactive system. The system consists of a control program, external hardware, and other peripheral auxiliary circuits. The functions include (1) inputs: heart rate, a measurement circuit for detection of physiological feedbacks of body fat (BMI); (2) output: electrical stimulus feedback-type circuit system. The system consists of an adjustable digital control circuit, low-current and high-resolution graphic LCD monitor to display image for convenience. An error-proofing mechanism was developed and clinical tests were performed, with various conditions, to prevent errors and danger. The system is expected to advance the development and application in cloud medical treatment and home care technology.
