Description
本發明係有關於一種整合性的觸控輸入裝置及其內部所用觸控辨識方法，更特別地是一種可以排除手掌誤觸的錯誤觸控偵測的觸控輸入裝置及觸控辨識方法。 The invention relates to an integrated touch input device and a touch recognition method therefor, and more particularly to a touch input device and a touch recognition method capable of eliminating false touch detection caused by palm touch.
目前市面上常見到的觸控技術，主要可分為電阻式、電容式、電磁式、紅外線式、光學式或超音波式等。電阻式的觸控面板發展已久，主要以單點式觸控技術為主，然而電阻式觸控無法在當觸控筆盤旋於觸控面板表面上方時即能偵測出是否已靠近觸控面板，也就是沒有感應距離，當手掌與手指同時碰觸此觸控面板時，也無法防止手掌誤觸時的錯誤觸控偵測。電容式的觸控面板主要以可實現多點觸控技術為主，但是這種觸控技術同樣無法在當手指或是觸控筆放置於觸控面板上方即可偵測出感應距離，同樣也無法防止手掌誤觸時的錯誤觸控偵測。 Currently, touch technologies commonly found on the market can be mainly classified into resistive, capacitive, electromagnetic, infrared, optical or ultrasonic. Resistive touch panels have been developed for a long time, mainly based on single-point touch technology. However, resistive touch cannot detect whether the touch pen is close to the touch when it is hovered over the surface of the touch panel. The panel, that is, there is no sensing distance, when the palm and the finger touch the touch panel at the same time, it cannot prevent the wrong touch detection when the palm is accidentally touched. The capacitive touch panel is mainly based on multi-touch technology, but the touch technology can not detect the sensing distance when the finger or the stylus is placed on the touch panel. It is impossible to prevent false touch detection when the palm is accidentally touched.
另外，電磁式的觸控面板或稱為手寫輸入裝置，具有較高精確度及解析度的優勢，被廣泛地運用在專業美工繪圖及工業製圖等領域，其技術上可以用有電池筆及無電池筆兩種來區分。無電池筆的電磁式手寫裝置的專利主要以Wacom公司的美國專利U.S.公告 號4,789,765、4,878,553、4,956,526以及7,005,843等專利為代表，其優點是具有感應距離，而且不怕手掌手肘壓於書寫區之上，但是其缺點只能單點輸入書寫，而且專用的電磁筆設計結構相對複雜許多，成本也較高。 In addition, the electromagnetic touch panel or the handwriting input device has the advantages of high precision and resolution, and is widely used in the fields of professional art drawing and industrial drawing, and the technology can be used with a battery pen and no. There are two types of battery pens to distinguish. The patent for the electromagnetic handwriting device without battery pen is mainly announced by the US patent U.S. of Wacom. Nos. 4,789,765, 4,878,553, 4,956,526, and 7,005,843 are representative of the patent, which has the advantage of sensing distance, and is not afraid of the palm elbow pressing on the writing area, but its shortcoming can only be written at a single point, and the special electromagnetic pen design structure is relatively It is much more complicated and costs more.

本發明的一些實施例會詳細描述如下。然而，除了詳細描述外，本發明還可以廣泛地在其他的實施例施行，且本發明的範圍不受限定，其以之後的專利範圍為準。 Some embodiments of the invention are described in detail below. However, the present invention may be widely practiced in other embodiments, and the scope of the present invention is not limited by the detailed description, which is subject to the scope of the following patents.
第一圖係顯示本發明之觸控輸入裝置的方塊圖。如第一圖所示，此觸控輸入裝置10主要包含觸控面板102、天線迴圈陣列104、數位訊號處理器106、掃描控制電路108與主處理器110。在本發明的觸控面板102上，無論是單點觸控或是多點觸控方式皆可以在此觸控面板102上實現。進一步來說，此觸控面板102可以是多點式的電阻式觸控面板、或是光學掃描式的觸控面板，只要可以實現單點觸控或是多點觸控的觸控面板都可以應用在本發明的觸控面板102上。當使用者碰觸到此觸控面板102時，會產生一觸控訊號。不同於傳統的觸控輸入裝置，本發明的觸控輸入裝置10在觸控面板102的下方設置了一個天線迴圈陣列104，此天線迴圈陣列104係用於感應在觸控面板102上書寫的觸控指示筆112所產生的電磁變化，進而傳出電磁感應訊號。數位訊號處理器106電性連接觸控面板102，其用於掃描偵測在觸控面板102上觸控訊號的位置，由於數位訊號處理器106對於觸控面板102的觸控偵測為習知技藝，故對於數位訊號處理器106的技術手段不再贅述。掃瞄控制電路108則用於週期性短暫地發射電磁場能量給處理觸控指示筆112，當觸控指示筆112接近觸控面板102與天線迴圈陣列104時，可因此感應出電磁感應訊號並依其遠近而有振幅的變化。最後，數位訊號處理器106與掃描控制電路108分別電性連接主處理器110，主處理器110根據數位訊號處理器106與掃描控制電路108所傳送的觸控訊號與電磁感應訊號比對二訊號位置的差異，並因此得以辨識出合理的觸控位置，以進行排除手 掌誤觸時的錯誤偵測。 The first figure shows a block diagram of a touch input device of the present invention. As shown in the first figure, the touch input device 10 mainly includes a touch panel 102, an antenna loop array 104, a digital signal processor 106, a scan control circuit 108, and a main processor 110. In the touch panel 102 of the present invention, both single-touch and multi-touch methods can be implemented on the touch panel 102. Further, the touch panel 102 can be a multi-point resistive touch panel or an optical scanning touch panel, as long as the single touch panel or the multi-touch touch panel can be used. It is applied to the touch panel 102 of the present invention. When the user touches the touch panel 102, a touch signal is generated. Different from the conventional touch input device, the touch input device 10 of the present invention is provided with an antenna loop array 104 under the touch panel 102, and the antenna loop array 104 is used for sensing writing on the touch panel 102. The touch stylus 208 changes the electromagnetic force generated by the pen 112, thereby transmitting an electromagnetic induction signal. The digital signal processor 106 is electrically connected to the touch panel 102 for scanning and detecting the position of the touch signal on the touch panel 102. The touch detection of the touch panel 102 by the digital signal processor 106 is known. The technical means, therefore, the technical means for the digital signal processor 106 will not be described again. The scan control circuit 108 is configured to periodically emit electromagnetic field energy to the touch stylus 112. When the touch stylus 112 approaches the touch panel 102 and the antenna loop array 104, the electromagnetic induction signal can be induced. There is a change in amplitude depending on its distance. Finally, the digital signal processor 106 and the scan control circuit 108 are electrically connected to the main processor 110, and the main processor 110 compares the touch signal and the electromagnetic induction signal transmitted by the digital signal processor 106 and the scan control circuit 108 to the second signal. The difference in position, and thus the ability to identify a reasonable touch position for exclusion Error detection when the palm is wrong.
依舊參閱第一圖，本發明之觸控輸入裝置10更包含一觸控指示筆112。此觸控指示筆112包含一振盪電路1122，在觸控指示筆112內加裝此振盪電路1122的目的是可以短暫地接收從天線迴圈陣列104所發射的電磁場能量，當天線迴圈陣列104停止發射能量時，振盪電路1122因有儲存能量，便能經由自身的線圈將訊號發射回來，當觸控指示筆112接近觸控面板102上方一定的距離之內，即可偵測到觸控指示筆112的位置座標，進而可依此位置座標來修正數位訊號處理器106的觸控偵測結果。另外，當使用者使用此觸控指示筆112在觸控面板102上方操作時，若在此時使用者的手掌不小心觸碰到了觸控面板102，由於手掌部份並不具有振盪電路1122，天線迴圈陣列104對於手掌的觸控部分的偵測並不反應，在主處理器110的處理時會針對觸控面板102所偵測的觸控位置與天線迴圈陣列104所偵測的觸控位置作比較，在比較的時候手掌誤觸的部分會被視為錯誤訊號，進而將手掌誤觸的部份排除，不會在電子裝置114的顯示螢幕上顯示。在此需要說明的事，此振盪電路1122在一較佳實施例中係為LC振盪電路結構，LC振盪電路結構為熟悉此技藝者所熟知，故不在此對LC振盪電路結構的電路原理作詳細描述。 Referring to the first figure, the touch input device 10 of the present invention further includes a touch stylus 112. The touch stylus 112 includes an oscillating circuit 1122. The oscillating circuit 1122 is added to the touch stylus 112 for temporarily receiving electromagnetic field energy emitted from the antenna loop array 104 when the antenna loop array 104 is received. When the energy is stopped, the oscillating circuit 1122 can transmit the signal through its own coil due to the stored energy. When the touch stylus 112 approaches a certain distance above the touch panel 102, the touch indication can be detected. The position coordinates of the pen 112 can further correct the touch detection result of the digital signal processor 106 according to the position coordinates. In addition, when the user uses the touch stylus 112 to operate over the touch panel 102, if the user's palm accidentally touches the touch panel 102 at this time, since the palm portion does not have the oscillation circuit 1122, The antenna loop array 104 does not respond to the detection of the touch portion of the palm. When the main processor 110 processes, the touch position detected by the touch panel 102 and the touch detected by the antenna loop array 104 are detected. When the control position is compared, the portion of the palm that is mistakenly touched during the comparison is regarded as an error signal, and the portion that is accidentally touched by the palm is excluded, and is not displayed on the display screen of the electronic device 114. In this case, the oscillating circuit 1122 is an LC oscillating circuit structure in a preferred embodiment. The LC oscillating circuit structure is well known to those skilled in the art, and therefore the circuit principle of the LC oscillating circuit structure is not detailed here. description.
第二圖係顯示本發明另一實施例之觸控輸入裝置的方塊圖。如第二圖所示，此觸控輸入裝置20主要包含觸控面板202、天線迴圈陣列204、數位訊號處理器206、多工器208、放大電路210、取樣電路212、類比數位轉換器214與主處理器216。同樣，在此實施例中， 無論是單點觸控或是多點觸控方式皆可以在此觸控面板202上實現。當使用者碰觸到此觸控面板202時，會產生觸控訊號。不同於第一圖之實施例，在此觸控輸入裝置20更包含多工器208、放大電路210、取樣電路212與類比數位轉換器214。多工器208用於接收天線迴圈陣列204的電磁感應訊號，且可以控制天線迴圈陣列204以短暫地發射電磁場能量給觸控指示筆218。放大電路210將電磁感應訊號放大傳送至取樣電路212，取樣電路212取樣電磁感應訊號的振幅，再將訊號傳送至類比數位轉換器214，經過類比數位轉換器的訊號轉換，最後將數位的取樣電磁感應訊號傳遞至主處理器216辨識。在此實施例中同樣具備觸控指示筆218，因為此觸控指示筆218包含一振盪電路2182，可以接收從天線迴圈陣列204所發射的電磁場能量，當振盪電路2182儲能之後，便會將訊號發射回來，當觸控指示筆218在觸控面板202上方時，即可偵測到觸控指示筆218的位置座標，除了可用於增加觸控面板202的增加精確度，進而可排除其他物體不小心觸碰到觸控面板202的錯誤觸控辨識。最後將正確的觸控位置顯示在電子裝置220上。 The second figure shows a block diagram of a touch input device according to another embodiment of the present invention. As shown in the second figure, the touch input device 20 mainly includes a touch panel 202 , an antenna loop array 204 , a digital signal processor 206 , a multiplexer 208 , an amplifying circuit 210 , a sampling circuit 212 , and an analog digital converter 214 . With the main processor 216. Also, in this embodiment, Both single-touch and multi-touch methods can be implemented on the touch panel 202. When the user touches the touch panel 202, a touch signal is generated. Different from the embodiment of the first figure, the touch input device 20 further includes a multiplexer 208, an amplifying circuit 210, a sampling circuit 212, and an analog digital converter 214. The multiplexer 208 is configured to receive electromagnetic induction signals from the antenna loop array 204 and may control the antenna loop array 204 to briefly emit electromagnetic field energy to the touch stylus 218. The amplifying circuit 210 amplifies the electromagnetic induction signal to the sampling circuit 212. The sampling circuit 212 samples the amplitude of the electromagnetic induction signal, and then transmits the signal to the analog digital converter 214, through the signal conversion of the analog digital converter, and finally the digital sampling electromagnetic The inductive signal is passed to the main processor 216 for identification. In this embodiment, the touch stylus 218 is also provided, because the touch stylus 218 includes an oscillating circuit 2182 that can receive the electromagnetic field energy emitted from the antenna loop array 204. When the oscillating circuit 2182 stores energy, When the touch stylus 218 is above the touch panel 202, the position coordinates of the touch stylus 218 can be detected, which can be used to increase the accuracy of the touch panel 202, thereby eliminating other The object inadvertently touches the wrong touch recognition of the touch panel 202. Finally, the correct touch position is displayed on the electronic device 220.
