自2007年Apple推出搭配 3.5吋能支援Multi-Touch功能的投射電容式多點觸控螢幕 iPhone 後，在全球即掀起一陣觸控螢幕風潮風潮。2009年10月Microsoft發表支援多點觸控操作介面的Windows 7作業平台，多點觸控技術、人性化操作介面的風潮將不斷地延燒，並已成為全球各業界亟欲投資開發的技術。
WHQL是微軟內部專門負責“Designed for Windows”認證的機構，其全名為Windows Hardware Quality Labs。Windows Logo認證是確保該裝置能夠在Windows 7系統平台上順利的運作。因此，經過微軟Windows 7作業系統的硬體相容性測試並獲得認證，不僅在Windows 7 作業系統下能夠發揮最佳的效能，更擁有最佳的相容性與穩定性。由於目前台灣微軟Logo認證，依認證規範“Windows Touch Test”文件說明，共有14個項目與量測步驟，每個步驟目前仍處於人工方式，以單手指或雙手指觸摸觸控螢幕並依面板上顯示目標圖案路徑（S）起始點描繪至（E）結束點。
本研究主要開發一種可以模擬人二根手指頭運動的「二點觸控面板自動描圖測試機」，可以運用在Windows 7作業系統相容性Logo認證測試自動化。
預期本研究所開發的「二點觸控面板自動描圖測試機」，將取代人為不確定因素與誤判，以自動化設備提昇驗證工作準確性和再現性，並符合認證要求規範INPUT-0046 “Windows Touch digitizers provide a high quality input experience”的準確和偏差要求值。

Since Apple unveiled iPhone in 2007, which features a 3.5-inch projective capacitive multi-touch panel, it has brought a whirlwind of multi-touch technology. Subsequently, Microsoft launched Windows 7 in October 2009, which is a platform providing supports for the multi-touch interface. It is beyond doubt that multi-touch technology and human interface are the big trends, and attracts the eyes of global investors.
WHQL stands for Windows Hardware Quality Labs, which is a division of Microsoft, and is responsible for the certification of “Designed for Windows”. Windows Logo Certification ensures the device works well on the Windows 7 platform. Therefore, a certified device that passed Microsoft Windows Hardware Compatibility Test can not only achieve the best performance under Windows 7 operating system, but also with optimal compatibility and stability. According to “Windows Touch Test” which validates the logo requirements, there are 14 necessary tests for Microsoft Logo Certification. However, each test needs to be executed manually at present, one or two fingers touch the panel and to move then from the starting point (S) to the ending point (E) along the line shown on the panel.
This research aims at developing an “auto-plotting two-contact touch panel tester”, which can simulate the movements of two fingers, and this tester can be applied to the automation of Windows 7 logo and compatibility certification tests.
We anticipate the “auto-plotting two-contact touch panel tester” can reduce the Human operating uncertainty and incorrect judgments, increase the accuracy of certification procedure with the automatic equipment, and meet the requirements for precision and deviation of INPUT-0046 “Windows Touch digitizers provide a high quality input experience.”
