　　摘要：現(xiàn)代生活中，方便、高效、完整的記錄信息變得越來越重要。常用的錄音筆等工具無法與筆記實現(xiàn)一一對應，常見的寫字板由于采用專用的書寫工具書寫過程不夠自然。為此我們設計了一種帶有同步語音功能的拓紙式手寫板。將普通紙張置于該手寫板之上，用戶可以使用普通筆在其上書寫，書寫結果可以同時通過紙介質(zhì)和電子文檔兩種形式保存。電子文檔輔助語音同步輸入，書寫內(nèi)容與語音實現(xiàn)直觀的圖像與語音的同步對應存儲和重現(xiàn)。系統(tǒng)具有使用自然、攜帶方便、成本低廉等優(yōu)點。該系統(tǒng)在教學與培訓、工業(yè)設計、醫(yī)學診療以及日常生活和工作交流等領域具有良好的實用價值。

　　Abstract：Nowadays，information is becoming more and more important. People are constantly striving to find faster and convenient ways of recording important data and messages completely. Common digital recording tools，such as Digital Voice Recorder can only record voice, and those who uses handwriting pad may find it inconvenient to use a special pen to write. So we designed a new kind of handwriting pad called "Rubbing Tablet with the Synchronous Phonic Synthesization". Users can put a piece of paper over the pad，and use a common pen to write on it. Our pad will store the message in a digital way，and record the user's voice at the same. When he wants to review his notes，he will find three forms of message: notes on paper，digital data in hard disk and the words he spoke. Convenience is the main attraction of our pad，and that means more than simple portability. It will have high application value in education，industrial design，medical treatment and other areas in daily life.
