Description
本發明是有關於一種訊號感測方法，且特別是有關於一種觸控點感測方法。The present invention relates to a signal sensing method, and more particularly to a touch point sensing method.
目前觸控面板技術大致上具有以下幾種類型：內嵌式、投射式電阻式、電容式、光學式、電磁式與超音波式等。以投射式電容觸控面板為例，目前廣泛應用在智慧型手機、平板電腦等其他類型的資訊處理裝置上。At present, touch panel technology generally has the following types: in-line type, projected type resistive type, capacitive type, optical type, electromagnetic type and ultrasonic type. For example, a projected capacitive touch panel is widely used in other types of information processing devices such as smart phones and tablet computers.
由於投射式電容觸控面板隨著環境改變會遭受到不同環境背景雜訊源影響，進一步影響觸控操作的靈敏度。因此，目前有部分的觸控點感測方式是利用單一個累積臨界計數器去判斷是否發生真實觸控點。然而當使用者在背景雜訊較強烈，亦或是容易受到不明雜訊干擾源(例如，手機射頻訊號、檯燈穩壓器周圍...等靜電干擾)的環境下進行觸控操作時，容易使所述的投射式電容觸控面板遭受到雜訊干擾，而產生誤報點並影響累積臨界計數器中累積值的正確性。Since the projected capacitive touch panel suffers from different environmental background noise sources as the environment changes, the sensitivity of the touch operation is further affected. Therefore, some touch point sensing methods currently use a single cumulative critical counter to determine whether a real touch point occurs. However, when the user performs touch operation in an environment where the background noise is strong, or is susceptible to unknown noise sources (for example, mobile phone RF signals, ambient light regulators, etc.), it is easy. The projected capacitive touch panel is subjected to noise interference, which generates a false alarm point and affects the correctness of the accumulated value in the cumulative critical counter.
舉例來說，如圖1所示，在無雜訊干擾的情況下，使用者可於觸控面板上進行單一觸控點的觸控操作，例如，從觸控起點Ts滑動至觸控終點Te，以進行書寫的動作。所述的觸控面板可對應於使用者的觸控操作顯示線條L1。For example, as shown in FIG. 1 , in the case of no noise interference, the user can perform a touch operation on a single touch point on the touch panel, for example, from the touch start point Ts to the touch end point Te. To perform the act of writing. The touch panel can display the line L1 corresponding to the touch operation of the user.
然而當使用者在雜訊干擾情況下，同樣的操作過程，卻可能因為雜訊干擾問題，使得目前累積臨界計數器中的累積值歸零，導致觸控操作出現觸控斷點的情形。所述的觸控面板則對應於使用者的觸控操作顯示線條L2與線條L3，而此觸控結果亦影響觸控操作的準確性與便利性。因此，目前所述的觸控點感測方法可能導致觸控面板的準確性與靈敏度大幅下降。However, when the user is in the case of noise interference, the same operation process may cause the accumulated value in the accumulated critical counter to be zero due to the noise interference problem, resulting in a touch break point in the touch operation. The touch panel displays the line L2 and the line L3 corresponding to the touch operation of the user, and the touch result also affects the accuracy and convenience of the touch operation. Therefore, the touch point sensing method currently described may cause the accuracy and sensitivity of the touch panel to be greatly reduced.
本發明提出一種觸控點感測方法，可增強判斷觸控點的真實位置，並抑制雜訊干擾源的影響，以達到提升觸控點的感測精確性。The invention provides a touch point sensing method, which can enhance the real position of the touch point and suppress the influence of the noise interference source, so as to improve the sensing accuracy of the touch point.
因此，本發明的觸控點感測方法，包括有下列步驟：首先，提供一個儲存區。接著，於第一時間點時偵測相應於一個觸控點的第一數值。接下來，於第一數值超出第一臨界值時，則使儲存區中對應於觸控點的判斷參數的值加一。於第一數值不超出第一臨界值時，則使所述的儲存區中對應於所述的觸控點的判斷參數的值歸零。以及於所述的判斷參數的值到達第二臨界值時，則判定對應的所述觸控點為被觸碰的狀態。Therefore, the touch point sensing method of the present invention includes the following steps: First, a storage area is provided. Then, the first value corresponding to one touch point is detected at the first time point. Next, when the first value exceeds the first threshold, the value of the determination parameter corresponding to the touch point in the storage area is incremented by one. When the first value does not exceed the first threshold, the value of the determination parameter corresponding to the touch point in the storage area is zeroed. And when the value of the determination parameter reaches the second threshold, it is determined that the corresponding touch point is in a touched state.
綜上所述，本發明的觸控點感測方法可在具有雜訊干擾源的環境下，加強觸控點的感測精確性。更具體的說，本發明透過建立具有多重觸控臨界值的儲存區，使儲存區中的每一儲存單元對應到多重觸控點其中之一。藉此，所述的儲存區的各儲存單元可分別累積計算個別觸控點是否已被觸發為真實觸控點。簡單來說，由於各個觸控點由個別獨立的儲存單元計算與處理，因此，即便在雜訊干擾環境中進行觸控操作，仍可有效判斷有無觸控點發生，亦可維持觸控操作的靈敏度與準確性。In summary, the touch point sensing method of the present invention can enhance the sensing accuracy of the touch point in an environment with a noise interference source. More specifically, the present invention enables each storage unit in the storage area to correspond to one of the multiple touch points by establishing a storage area having multiple touch thresholds. Thereby, each storage unit of the storage area can separately calculate whether the individual touch points have been triggered as real touch points. In short, since each touch point is calculated and processed by a separate storage unit, even if the touch operation is performed in a noise interference environment, it is still possible to effectively determine whether or not a touch point occurs, and the touch operation can be maintained. Sensitivity and accuracy.
為讓本發明之上述和其他目的、特徵和優點能更明顯易懂，下文特舉較佳實施例，並配合所附圖式，作詳細說明如下。The above and other objects, features and advantages of the present invention will become more <RTIgt;
請參照圖2，圖2為本發明實施例的觸控點感測方法步驟流程圖。首先，在步驟S201中，提供一個儲存區。所述的儲存區具有暫時性與/或永久性儲存數據的能力。所述的儲存區可例如是揮發性記憶體(例如，DRAM、EDRAM、SRAM等)與/或非揮發性記體(ROM、PROM、EAROM、EPROM、EEPROM及快閃記憶體等)。Please refer to FIG. 2. FIG. 2 is a flow chart of steps of a touch point sensing method according to an embodiment of the present invention. First, in step S201, a storage area is provided. The storage area has the ability to temporarily and/or permanently store data. The storage area may be, for example, a volatile memory (eg, DRAM, EDRAM, SRAM, etc.) and/or a non-volatile record (ROM, PROM, EAROM, EPROM, EEPROM, flash memory, etc.).
所述的儲存區可設置於智慧型手機、平板電腦或其他類型的資訊處理裝置中，或者是設置於所述資訊處理裝置的外部，並透過有線或無線傳輸技術傳輸所述的數據。更進一步說，所述的儲存區可例如是由至少一個儲存單元所組成。所述的儲存單元可例如是緩存器與/或計數器。換句話說，各個緩存器或計數器係相應於記錄一個觸控點。The storage area may be disposed in a smart phone, a tablet or other type of information processing device, or disposed outside the information processing device, and transmit the data through a wired or wireless transmission technology. Furthermore, the storage area can be composed, for example, of at least one storage unit. The storage unit can be, for example, a buffer and/or a counter. In other words, each buffer or counter corresponds to recording a touch point.
接著，在步驟S203中，於第一時間點時偵測相應於一個觸控點的第一數值。舉例來說，可透過掃瞄觸控面板的過程得知目前觸控點的數量，並取得相應於觸控按壓能量的數值(即所述的第一數值)。當所述的觸控按壓能量愈強時，則第一數值愈大。反之，當所述的觸控按壓能量愈弱時，則第一數值愈小。換句話說，所述的觸控按壓能量與第一數值成一正比的關係。所述的第一數值可例如是大於等於零的正整數。另外，在本發明實施例中，所述的第一數值的預設值為零。Next, in step S203, the first value corresponding to one touch point is detected at the first time point. For example, the number of current touch points can be known through the process of scanning the touch panel, and the value corresponding to the touch pressing energy (ie, the first value) can be obtained. When the touch pressing energy is stronger, the first value is larger. On the contrary, when the touch pressing energy is weaker, the first value is smaller. In other words, the touch pressing energy is proportional to the first value. The first value may be, for example, a positive integer greater than or equal to zero. In addition, in the embodiment of the present invention, the preset value of the first value is zero.
接下來，在步驟S205中，判斷第一數值是否超出第一臨界值。舉例來說，所述的判斷程序可透過數據處理器(圖中未示)執行，或者可透過其他具有數值比較功能的軟體程式與/或硬體電路實現所述的判斷程序。藉由比較第一數值與第一臨界值的變化情形，可初步判斷是否有觸控點發生。Next, in step S205, it is determined whether the first value exceeds the first critical value. For example, the determining program may be executed by a data processor (not shown) or may be implemented by other software programs and/or hardware circuits having a numerical comparison function. By comparing the change of the first value with the first threshold, it can be initially determined whether a touch point occurs.
在步驟S205中所述的觸控點可例如由雜訊干擾所引起與/或使用者實際按壓所引起。另外，在本發明實施例中，所述的第一臨界值的預設值為零。The touch point described in step S205 can be caused, for example, by noise interference and/or actual user press. In addition, in the embodiment of the present invention, the preset value of the first threshold is zero.
在步驟S207中，於所述的第一數值超出第一臨界值時，使儲存區中對應於觸控點的判斷參數的值加一。所述的判斷參數可用來表示觸控點是否隨時間持續按壓累積。在本發明實施例中，所述的判斷參數的預設值為零。舉例來說，當使用者實際按壓或雜訊干擾時，第一數值即反應出當前的觸控按壓能量，例如為25。此時，儲存區中對應於觸控點的判斷參數的值加一，例如，判斷參數的值由0變為1。接著，若於第二時間點，且第一數值持續超過第一臨界值時，則儲存區中對應於觸控點的判斷參數的值持續加一，例如，判斷參數的值由1變為2，依此類推。In step S207, when the first value exceeds the first threshold, the value of the determination parameter corresponding to the touch point in the storage area is incremented by one. The determining parameter can be used to indicate whether the touch point continues to press and accumulate over time. In the embodiment of the present invention, the preset value of the determining parameter is zero. For example, when the user actually presses or the noise interferes, the first value reflects the current touch pressing energy, for example, 25. At this time, the value of the judgment parameter corresponding to the touch point in the storage area is incremented by one, for example, the value of the judgment parameter is changed from 0 to 1. Then, if at the second time point, and the first value continues to exceed the first threshold, the value of the determination parameter corresponding to the touch point in the storage area is continuously incremented by one, for example, the value of the determination parameter is changed from 1 to 2. ,So on and so forth.
另外，在本發明的另一實施例中，於判斷參數的值不為零，且第一時間點所對應的第一數值與第二時間點所對應的第一數值的差值小於等於一個門檻值時，則將儲存區中對應於觸控點的判斷參數的值加一。所述的差值為絕對差值。所述的門檻值可由使用者自行調整與設定。舉例來說，門檻值為10且對應於觸控點的判斷參數的值不為零時，第一時間點對應的第一數值為20，而第二時間點所對應的第一數值的差值為25，因此，第一數值的差值為5，可初步判定為同一觸控點，並將對應於觸控點的判斷參數的值加一。In addition, in another embodiment of the present invention, the value of the determination parameter is not zero, and the difference between the first value corresponding to the first time point and the first value corresponding to the second time point is less than or equal to a threshold. When the value is used, the value of the judgment parameter corresponding to the touch point in the storage area is incremented by one. The difference is an absolute difference. The threshold value can be adjusted and set by the user. For example, when the threshold value is 10 and the value of the determination parameter corresponding to the touch point is not zero, the first value corresponding to the first time point is 20, and the difference of the first value corresponding to the second time point is 25, therefore, the difference of the first value is 5, which can be initially determined as the same touch point, and the value of the judgment parameter corresponding to the touch point is incremented by one.
另外，若於判斷參數的值不為零，且第一時間點所對應的第一數值與第二時間點所對應的第一數值的差值大於一門檻值時，則將判斷參數的值歸零。舉例來說，門檻值為10且於判斷參數的值不為零時，第一時間點對應的第一數值為20，而第二時間點所對應的第一數值的差值為8。因此，第一數值的差值為12，可初步判定不是同一觸控點，或是判定屬於雜訊干擾情況，並將判斷參數的值歸零。In addition, if the value of the parameter is not zero, and the difference between the first value corresponding to the first time point and the first value corresponding to the second time point is greater than a threshold, then the value of the parameter is determined. zero. For example, if the threshold value is 10 and the value of the determination parameter is not zero, the first value corresponding to the first time point is 20, and the difference of the first value corresponding to the second time point is 8. Therefore, the difference of the first value is 12, and it can be initially determined that it is not the same touch point, or it is determined to be a noise interference condition, and the value of the judgment parameter is zeroed.
在步驟S213中，於第一數值不超出第一臨界值時，使所述的儲存區中對應於觸控點的判斷參數的值歸零(或者清除為預設值)，並回到步驟S203持續進行觸控點的感測與判定。舉例來說，當使用者未實際按壓或雜訊干擾消失時，第一數值即反應出當前的觸控按壓能量，例如為0。此時，儲存區中對應於觸控點的判斷參數的值歸零，例如，若原先判斷參數的值為1或2時，則目前判斷參數的值由1變為0，或由2變為0，依此類推。In step S213, when the first value does not exceed the first threshold, the value of the determination parameter corresponding to the touch point in the storage area is reset to zero (or cleared to a preset value), and the process returns to step S203. The sensing and determination of the touch point is continued. For example, when the user does not actually press or the noise interference disappears, the first value reflects the current touch pressing energy, for example, 0. At this time, the value of the judgment parameter corresponding to the touch point in the storage area is reset to zero. For example, if the value of the original judgment parameter is 1 or 2, the value of the current judgment parameter is changed from 1 to 0, or 2 0, and so on.
另外，在本發明的另一實施例中，若於第一數值不超出第一臨界值時，使所述的儲存區中對應於觸控點的判斷參數的值歸零，亦可判定對應觸控點為無觸碰的狀態。In addition, in another embodiment of the present invention, if the value of the determination parameter corresponding to the touch point in the storage area is zeroed when the first value does not exceed the first threshold, the corresponding touch may also be determined. The handle is in a state of no touch.
接下來，在步驟S209中，確認判斷參數的值是否到達第二臨界值？所述的確認程序可透過數據處理器(圖中未示)執行，或者可透過其他具有數值比較功能的軟體程式與/或硬體電路實現所述的確認程序。藉由比較判斷參數的值與第二臨界值的變化情形，可再次判斷是否有觸控點發生。另外，若確認判斷參數的值未到達第二臨界值時，則回到步驟S205持續進行觸控點的判定程序。Next, in step S209, it is confirmed whether the value of the determination parameter reaches the second critical value. The confirmation program may be executed by a data processor (not shown) or may be implemented by other software programs and/or hardware circuits having a numerical comparison function. By comparing the value of the judgment parameter with the change of the second threshold value, it can be judged again whether or not a touch point occurs. Further, if it is confirmed that the value of the determination parameter does not reach the second critical value, the process returns to step S205 to continue the determination process of the touch point.
在步驟S211中，於確認判斷參數的值到達第二臨界值時，判定對應的觸控點為被觸碰的狀態，並回到步驟S203持續進行觸控點的感測與判定。舉例來說，在本發明實施例中，所述的第二臨界值的預設值為3。因此，當判斷參數持續加一至3時，判斷參數的值到達第二臨界值，則判定對應觸控點為被觸碰的狀態，以輸出判定結果至下一級電路(圖中未示)。所述的第二臨界值可由使用者自行調整或設定。In step S211, when it is confirmed that the value of the determination parameter reaches the second threshold value, it is determined that the corresponding touch point is in the touched state, and the process returns to step S203 to continue the sensing and determination of the touch point. For example, in the embodiment of the present invention, the preset value of the second threshold is 3. Therefore, when the judgment parameter continues to increase by one to three, the value of the determination parameter reaches the second critical value, and then the corresponding touch point is determined to be the touched state, so that the determination result is output to the next-stage circuit (not shown). The second threshold value can be adjusted or set by the user.
所述的第二臨界值的大小可影響觸控面板的感測靈敏度或速度。舉例來說，若所述的第二臨界值愈大，則觸控點的判定時間愈久。反之，若所述的第二臨界值愈小，則觸控點的判定時間愈短。The magnitude of the second threshold may affect the sensing sensitivity or speed of the touch panel. For example, if the second threshold value is larger, the determination time of the touch point is longer. On the contrary, if the second threshold value is smaller, the determination time of the touch point is shorter.
以下舉例說明觸控點判定的過程。請參照圖3A至圖3D，圖3A至圖3D為本發明實施例之觸控點判定過程示意圖。如圖3A所示，第一儲存區31、第二儲存區33與第三儲存區35可組成觸控點計數矩陣300。第一儲存區31可由5個儲存單元組成。同樣的，第二儲存區33與第三儲存區35可分別由5個儲存單元組成。The following is an example of the process of touch point determination. Please refer to FIG. 3A to FIG. 3D . FIG. 3A to FIG. 3D are schematic diagrams of a touch point determination process according to an embodiment of the present invention. As shown in FIG. 3A, the first storage area 31, the second storage area 33, and the third storage area 35 may constitute a touch point counting matrix 300. The first storage area 31 can be composed of 5 storage units. Similarly, the second storage area 33 and the third storage area 35 can be composed of 5 storage units, respectively.
值得一提的是，各儲存區中的各儲存單元係對應記錄於一個觸控點。舉例來說，儲存單元31a、儲存單元33a與儲存單元35a可用來記錄單一個觸控點的狀態，而儲存單元31b、儲存單元33b與儲存單元35b可用來記錄另一個觸控點的狀態。另外，在所述的觸控點計數矩陣300中，第一臨界值預設為0，而判斷參數的值預設為0，而第二臨界值預設為3。It is worth mentioning that each storage unit in each storage area is correspondingly recorded in one touch point. For example, the storage unit 31a, the storage unit 33a and the storage unit 35a can be used to record the state of a single touch point, and the storage unit 31b, the storage unit 33b and the storage unit 35b can be used to record the state of another touch point. In addition, in the touch point counting matrix 300, the first threshold is preset to 0, and the value of the determination parameter is preset to 0, and the second threshold is preset to 3.
首先，在第一時間點t時，使用者於觸控面板上進行觸控操作，並透過掃瞄偵測的過程取得相應於觸控按壓能量(或雜訊觸控點)的第一數值。所述的第一數值分別記錄於第一儲存區31的儲存單元中，分別為10、20、30、0、0。此時，於第一數值超過第一臨界值時，使第二儲存區33的儲存單元中的判斷參數的值加一，分別為1、1、1、0、0。First, at the first time point t, the user performs a touch operation on the touch panel, and obtains a first value corresponding to the touch pressing energy (or the noise touch point) through the scanning detection process. The first values are recorded in the storage unit of the first storage area 31, which are respectively 10, 20, 30, 0, 0. At this time, when the first value exceeds the first critical value, the value of the determination parameter in the storage unit of the second storage area 33 is increased by one, which are 1, 1, 1, 0, and 0, respectively.
接下來，如圖3B所示，在第二時間點t+1時，第一儲存區31只剩下兩個儲存單元中記錄有第一數值，分別為0、22、0、25、0。此時，當第一儲存區31中的第一數值為零時，則將第二儲存區33中對應的儲存單元的判斷參數的值清除為零或預設值。同時，儲存單元31b所對應的儲存單元33b中的判斷參數的值繼續加一，以及儲存單元31d所對應的儲存單元33d中的判斷參數的值加一。另外，若第二時間點t+1時，第一儲存區31中所對應的第一數值為零時，則將第二儲存區33中對應的儲存單元中的判斷參數的值歸零。Next, as shown in FIG. 3B, at the second time point t+1, the first storage area 31 has only two storage units recorded with the first value, which are 0, 22, 0, 25, and 0, respectively. At this time, when the first value in the first storage area 31 is zero, the value of the determination parameter of the corresponding storage unit in the second storage area 33 is cleared to zero or a preset value. At the same time, the value of the determination parameter in the storage unit 33b corresponding to the storage unit 31b continues to increase by one, and the value of the determination parameter in the storage unit 33d corresponding to the storage unit 31d is incremented by one. In addition, if the first value corresponding to the first storage area 31 is zero when the second time point t+1, the value of the determination parameter in the corresponding storage unit in the second storage area 33 is zeroed.
接下來，如圖3C所示，在第三時間點t+2時，第一儲存區31中記錄有第一數值，分別為35、21、12、30、0。第二儲存區33對應記錄有判斷參數的值，分別為1、3、1、2、0。此時，儲存單元31b所對應的儲存單元33b中的判斷參數的值繼續加一，並且使判斷參數的值到達第二臨界值3。因此，第三儲存區35的儲存單元35b由0變為1，則表示有一個觸控點產生，並判定為被觸碰的狀態。另外，儲存單元31d所對應的儲存單元33d中的判斷參數的值繼續加一。Next, as shown in FIG. 3C, at the third time point t+2, the first value is recorded in the first storage area 31, which are 35, 21, 12, 30, and 0, respectively. The second storage area 33 corresponds to a value in which the judgment parameter is recorded, and is 1, 3, 1, 2, and 0, respectively. At this time, the value of the determination parameter in the storage unit 33b corresponding to the storage unit 31b continues to increase by one, and the value of the determination parameter is brought to the second critical value 3. Therefore, when the storage unit 35b of the third storage area 35 is changed from 0 to 1, it indicates that one touch point is generated and is determined to be in a touched state. In addition, the value of the determination parameter in the storage unit 33d corresponding to the storage unit 31d continues to increase by one.
接下來，如圖3D所示，在第四時間點t+3時，第一儲存區31中記錄有第一數值，分別為0、20、0、28、0。第二儲存區33對應記錄有判斷參數的值，分別為0、4、0、3、0。此時，儲存單元31b所對應的儲存單元33b中的判斷參數的值繼續加一，以及儲存單元31d所對應的儲存單元33d中的判斷參數的值繼續加一，並且使判斷參數的值到達第二臨界值3。因此，第三儲存區35的儲存單元35d由0變為1，則表示有第二個觸控點產生，並判定為被觸碰的狀態。另外，第三儲存區35的儲存單元35b持續為1，則表示判定為持續被觸碰的狀態。Next, as shown in FIG. 3D, at the fourth time point t+3, the first value is recorded in the first storage area 31, which are 0, 20, 0, 28, and 0, respectively. The second storage area 33 corresponds to a value in which the judgment parameter is recorded, and is 0, 4, 0, 3, and 0, respectively. At this time, the value of the determination parameter in the storage unit 33b corresponding to the storage unit 31b continues to increase by one, and the value of the determination parameter in the storage unit 33d corresponding to the storage unit 31d continues to increase by one, and the value of the determination parameter is reached. The second critical value is 3. Therefore, when the storage unit 35d of the third storage area 35 is changed from 0 to 1, it indicates that a second touch point is generated and is determined to be touched. Further, when the storage unit 35b of the third storage area 35 continues to be 1, it indicates that the storage unit 35b is continuously touched.
綜上所述，本發明的觸控點感測方法可在具有雜訊干擾源的環境下，加強觸控點的感測精確性。更具體的說，本發明透過建立具有多重觸控臨界值的儲存區，使儲存區中的每一儲存單元對應到多重觸控點其中之一。藉此，所述的儲存區的各儲存單元可分別累積計算個別觸控點是否已被觸發為真實觸控點。簡單來說，由於各個觸控點由個別獨立的儲存單元計算與處理，因此，即便在雜訊干擾環境中進行觸控操作，仍可有效判斷有無觸控點發生，亦可維持觸控操作的靈敏度與準確性。In summary, the touch point sensing method of the present invention can enhance the sensing accuracy of the touch point in an environment with a noise interference source. More specifically, the present invention enables each storage unit in the storage area to correspond to one of the multiple touch points by establishing a storage area having multiple touch thresholds. Thereby, each storage unit of the storage area can separately calculate whether the individual touch points have been triggered as real touch points. In short, since each touch point is calculated and processed by a separate storage unit, even if the touch operation is performed in a noise interference environment, it is still possible to effectively determine whether or not a touch point occurs, and the touch operation can be maintained. Sensitivity and accuracy.
