Description of the Invention: [Technical Field of the Invention] The side method of the present invention is a method for detecting a gesture of an anti-noise touch panel. [Prior Art] A capacitive touch panel is an input device that performs Ο (4) by the tape of a finger (touch). When touching the object _ control panel, or sliding on the touch panel, the capacitance on the difficult side will change. By the technology of changing the capacitance of copper, the cursor representing the touch object can be calculated. The amount of movement. Because the capacitive touch panel is thin, it can be designed in thin notebook computers, keyboards, digital players, and the like. The first figure is a two-dimensional capacitive touch panel (10), which includes: a panel 1〇2, a Y-axis sensing layer 1〇4, an insulating layer ι6, a χ-axis sensing layer 10(10), and a 底板 bottom plate 11 When the Putian finger 112 touches the panel 102, the position touched by the Putian finger 112 will have a relative capacitance of 4, that is, the axis-money amount. The control circuit of the money contact control panel 1〇0 can convert the change of the capacitance on the touch panel into a sense. According to the measurement of the sensing amount, the position of the hand, the amount of displacement, and the direction of movement can be determined.曰 $Technology t 'To confirm the touch is; ^ Touch the capacitive touch panel material n the first method is based on the size of the thief should be judged as 'Figure 3, when When the sensing amount is greater than the critical value, the table 201007532 = the object touches the touch panel 100; otherwise, when the sensing amount is less than the critical value, the _^ ___ plate 1 or the touch surface has no second method. The detected amount of the sensed quantity is used as the judgment basis, and the fourth rider does not 'nuclear quantity 1: when it is greater than the threshold value th, it means that the touch object touches the panel 1QQ, and vice versa, the #inductive quantity Less than the critical value

panel 1 or there is no touch on the touch panel. Both of the above methods are susceptible to interference from outside noise and lead to erroneous judgment. In addition, when the touch object is clicked, dragged, double-clicked, or otherwise gestured on the touch panel 五 (5), the touch, touch, or the touch of the touch object on the touch panel 1 〇〇 As a user who uses the touch panel 1GQ for the first time or the touch panel 1QQ operation, the touch panel 100 cannot recognize the action of the maker, and thus causes an operation malfunction. Therefore, how to develop a gesture detection method that can prevent noise interference has become the focus of touch panel technology development. SUMMARY OF THE INVENTION In view of the above problems in the prior art, the present invention provides a method for measuring a touch object of a touch panel, the purpose of which is to avoid the interference of the touch of the touch object caused by the interference of the noise. 201007532 In order to achieve the above object, the present invention provides a touch panel touch object method: a method in which a touch object touches the touch panel and moves away from the touch panel to move the material on the touch panel A variety of unique gestures. [Embodiment] When the touch object touches the touch panel, there is a corresponding change in the amount of sensing. By changing the trend of the measured amount of the debt, it can be confirmed that this is a true touch touch, rather than a miscellaneous. (4) The method of the present invention will be described in the case of the substation _τ_, including: Α _ acknowledgment of the touch object touch detection method; β. the side method of confirming the touch object leaving; c the side method of the touch object movement 〇DragGesture detection method. The following are respectively explained: A. Confirming the touch detection method of the touch object Touching the touch object for the touch panel, most of the time, it will not suddenly appear, or suddenly disappear; the foot, forming a touch on the touch panel The amount of inductance that appears or disappears on the touch panel changes, there are some established trends, and there is a certain numerical stability.凊 Refer to Figure 5, which is an example of the change in the amount of sensing touched by the touch object on the touch panel, which shows the amount of sensing detected after the sensing amount is less than the critical value th (this threshold is a negative value). The change 'the towel, which has eight points for the X-axis value corresponding to a certain γ _ line, is persuasion, Χ1, Χ2, Χ3, Χ4, Χ5, Χ6, Χ7. The curve 202 is the amount of induction detected this time, and the curve 2 (five) is the amount of inductance from the previous to the second. Figure 6 is the difference between the two inductive quantities in 2010, each time 201007532 ("X0 7 this amount of induction minus the last induction"), also the I point sensing difference dV, Figure 7 shows Waveform of the measured signal 2〇4. For the reference of the 5th, 6th, and 7th month, when the amount of induction measured by the field on the side touch panel is less than the critical value (as shown in Figure 5) ), the detection signal 204 is changed from the low level to the high level (as shown in Fig. 7). Then, at the time TDown Detect Temple, the amount of the touch panel is increased, and the detected amount of the touch is detected. 202 subtracts the previous sense measurement 2〇〇, and obtains the point sensing difference dV′ as shown in FIG. 6 . If the point sensing difference dv obtained in the time D (−4) is a negative value, it means that there is a touch. The touch object touches the touch panel. This type of judgment is performed by measuring the amount of inductive debt twice in a preset time. If there is a trend of decreasing the amount of induction, and the trend of reduction is consistent, it means touch. The object does touch the touch panel. If it is the interference of noise, the amount of change between the two times before and after is not easy to trend. Consistency B. Confirmation of the method of detecting the touch of the touch object The present invention can confirm the touch of the touch object by the above-mentioned method of detecting the touch of the touch object, and the touch object is reversed in the touch. That is, the departure of the touch object must also be confirmed by an effective method. Figure 8 shows the change in the amount of inductance after the amount of sensing on the touch panel is greater than the threshold value th. The curve 212 is the detected sensor. Quantity, curve 210 is the amount of sensing detected last time. Figure 9 is the difference between each point of the two sensing quantities in Figure 8 (the amount of the sensing of point X0~7 minus the last sensing amount) ), also 8 201007532: two sensed difference dV, the first Q _ test signal 214 _ map. Figure 帛9 and the first 〇胄, touch the touch object, once _ to the amount of money, As shown in the eighth example, the signal 214 is changed from the same level to the low level, as shown in the first _, and then continues to _ the touch panel's sensing amount in the time _ _ _ _ _ _ _ The amount 212 is subtracted from the last sensed measurement 210 to obtain the point sensing difference dv, as shown in Fig. 9, if at the time of the heart, the resulting point feeling The difference value heart is positive value ' indicates that the touch object leaves the touch panel. C. Confirm the touch object movement detection method to confirm the touch object touch and leave method, you can do other motion detection and Confirm, for example, the movement of the touch object on the touch panel. The movement of the touch object on the touch panel must also be confirmed to avoid touching due to noise or slight jitter of the touch object. The position of the object is misjudged, and the movement of the cursor is misjudged. Fig. 11 is a graph showing the change of the amount of the touch when the touch object moves from rest to right, wherein the curve 222 is the amount of the detected amount, and the curve 220 is the last detected. The measured amount of induction. Fig. 12 is the difference between each point of the two inductive quantities in Fig. 11 (this amount of induction of the point X0~7 minus the amount of the previous induction), that is, the point sensing difference The value dV. After the disc touches the touch panel, the sensor continuously detects the amount of the touch on the touch panel and calculates the difference Δ between the detected amount 222 and the last detected point. The point sensing amount difference dV of the touch object sensing amount to the left side (first direction) of 201007532 maintains an increasing trend within the preset time T_ngdetect, and the point sensing amount difference of the sensing amount to the right side (second direction) The dV maintains a decreasing trend', indicating that the touch object moves from the left to the right; on the other hand, when the sensed amount dV of the sensed amount to the left maintains a decreasing trend, the sensed amount of the sensed amount to the right The difference dV indicates that the touch object is moved to the left from the standstill. As shown in the figure and Figure 12. D. Drag Gesture Detection Method Fig. 13 shows a waveform diagram of the detection signal 31〇 and the output signal 32〇, where the 'output signal 320' includes gesture signals 322, 324, 326, and 328. When the touch object is touched for the first time, the side key 31Q is changed from the low level to the 冋 position as shown in the 13th ®. If it is determined that it is in compliance with the "Detection method for the touch of a touch object", the "Method for confirming the movement of the touch object" is used to determine whether the touch object is on the touch panel. If it is true that it is moving on the touch panel, it is set to turn gestures; if 総 _ age is not determined to be a moving gesture on the touch panel, then the left side of the touch object - the male open touch panel f The signal 310 is converted from a high level to a low level. Next, if the detection method of the true touch is removed, the gesture signal 322 is initialized (for example, the button presses the money or presses the signal that the touch object is equal to zero), and the touch object is calculated to leave the touch. The departure time T1 of the panel, if the departure time τι ^ is in the reference time Ta and the side _ the second touch panel of the touch object, the L number 31Q is detected again by the solution _ is a high level. After confirming that the touch object touches the touch 201007532 panel, that is, after the "detection method for confirming the touch of the touch object", it is determined whether the touch object is touched according to the "detection method for detecting the movement of the touch object". Moving on the panel, if the touch object moves on the touch panel, the position of the touch object is calculated, and the gesture signal 322 and the send position information are maintained to generate a gesture signal 324 (eg, a composition signal of the button press and position information). When the touch object is detected to leave the touch panel for the second time, the side signal 310 is changed from the high level to the low level, and the detection of the sensing quantity is determined to be in accordance with the "detection method for confirming the exit of the touch object". At the same time, the junction + potential signal 324 is calculated, and then the departure time of the touch object leaving the touch panel is calculated. If the departure time Τ2 is less than the reference time Tb, and the touch object is detected for the third time, the side signal 310 is changed from the low level to the high level. When the detection of the sensing quantity is determined to be in accordance with the "detection method for confirming the movement of the touch object", it is determined whether the touch object moves on the touch panel, and if the touch object is confirmed to move on the touch panel, the touch is calculated. Position of the object, and maintain the gesture signal and the sent position information again, and generate a gesture signal 326 (for example, a key press and a component signal of the position _ m). When the touch object is detected to leave the touch panel for the third time, the _ signal 310 is changed from the high level to the low level, and the gesture signal 326 is ended when it is determined that the "detection method for confirming the touch off" is met. (4) Repeat the above green until after confirming the touch __ control panel, that is, after the "method of confirming the touch of the touch object", according to the "side method of confirming the movement of the touch object", and judging that the touch object is The touch panel does not move, and the touch object _ touch panel is detected. The _ signal 31Q is changed from the high level to the low 11 201007532 level 'determined to meet the "detection method for the touch object to leave" gesture Signal 328 (eg, a button release signal) ends gesture signal 322. The towel, the position #秘为麟赖, the relative movement of the gram coordinate touch object; and the absolute coordinate is the coordinate value generated by the fixed position (such as the center point or corner of the inspection panel) as the origin, and the relative coordinates are The relative position (for example, the position of the touch object _ control surface (four)) is taken as the reference occupational value, and the relative movement amount is the amount of movement relative to the touch object. The image shown in Fig. 14 is another embodiment in which waveforms of the detection signal 330 and the output signal 340 are displayed, and the output signal 34 includes gesture signals 342, 344, 346, 348, and 35 。. When the touch panel is touched by the change amount of the sensing amount, the M measurement signal 33 is turned from the low level to the high level. After confirming that the touch panel touches the touch panel, that is, after the "method of confirming the touch of the touch object", the "detection method of the movement of the touch object" is judged to be on the surface of the touch panel. If the touch is on the _ control panel, it is determined to be a moving gesture; if the touch object is not determined to be a moving gesture on the touch panel, 贞彳在伽,] to touch the lion to leave the touch panel At the time, the detection L number 330 is changed from the south level to the low level. After that, when it is determined that "the gamma method of confirming the touch away" is determined, the gesture Wei 342 is initialized (for example, the button presses the button or the button is pressed and the touch object displacement amount is equal to zero), and the touch object is calculated to leave the touch. The departure time of the panel is D 3. If the departure time τ3 is less than the reference time Tc Β ’ ’ and the touch object is detected to touch the touch panel for the second time, the detection signal 12 201007532 330 is again changed from the low level to the high level. After confirming that the touch object touches the touch panel, that is, it conforms to the "detection method of touch object touch", according to the "side method of confirming the touch object pin", whether the touch object touches the panel or not. . If the touch object moves on the touch panel, the position of the touch object is calculated, and the gesture signal 342 and the send position information are maintained, and a gesture signal 344 (e.g., a composition signal of the key press and position information) is generated. When the side touches the touch panel for the second time, the detection signal 33 turns from the high level to the low level. And determining that the 〇 is in compliance with the “detection method of the touch object”, the end gesture signal 344 is calculated, and the departure time of the touch object leaving the touch panel is calculated, and if the departure time D4 is less than the reference time Td, the detection touch object is detected. The third time the touch panel is touched, the side signal 〇p is again changed from the low level to the still position. Next, after determining that the touch object touches the touch panel, that is, it conforms to the "detection method of the touch of the touch object", according to the side method of confirming the movement of the touch object, it is determined whether the touch object is touched. The touch panel is mixed with the crane, the position of the shop, and the gesture signal 342 is again maintained and the position information is sent, and a gesture signal 346 is generated (for example, a composition signal of the button press and the position information). When the touch object is detected to leave the touch panel for the third time, the detection signal 31G is changed from the high level to the low level, and the _ determination of the sensing amount is in accordance with the "side method of confirming the touch away". Signal 346. The above method is continuously repeated until the touch object leaves the touch panel, and the fine signal 310 is changed from the high level to the low level, and the determination is consistent with the "detection method of confirming the touch 13 201007532 object leaving", and the gesture signal is ended. 348 (for example, the key pressing and the composition field of the position information); after the reference _Td, if the touch panel is not succeeded to the panel again, the gesture is sent as a button signal to end the gesture signal 342. The position information can also be an absolute coordinate, relative to the relative movement of the coordinates or the touch object. 15A to D are closed to an operation example of Fig. 13. Referring to FIG. 15A, the touch object 41 〇 touches the touch panel 420 and then leaves. During this period, the touch object 410 does not move on the touch panel 420, and the cursor on the display 43 is located at the position A, and then touches The control panel 42 sends an initialization signal, and the cursor paste on the display 43 is still at position A. Please refer to the first _ _, the touch object 410 touches the touch panel 42 again during the reference time, during which the touch object moves on the touch panel 420, and the touch panel 42 〇 calculates the touch The location of the 1641G' maintains the initialization signal and the send location information. The display ❹11 430 upstream marker 440 moves in the direction in which the touch object 410 moves, for example, from position to position Β. Referring to page 15C, the touch object 41 触 touches the touch panel 420 again and away during the reference time, during which the touch object 41 移动 moves on the touch panel 420 'the touch panel 42 〇 calculates the touch The position information of the object 41' is maintained and the initialization signal and the sent position information are maintained, and the upstream label of the display 43 moves in the direction in which the touch object moves, for example, from the position b to the position C. Please refer to FIG. 15D, the touch object 41 touches the touch 201007532 panel 420 within the reference time and then leaves 'the touch object 410 does not move on the touch panel 42〇 during this period, and then the touch panel 42 sends out The signal is terminated to end the initialization signal, and the cursor 44 on display 430 is stopped at position c. In the present embodiment, the 15B~C_ operation can be repeated until the cursor 440# is reached to the desired position, and the initialization signal is ended, thereby making the operation of the touch panel 42〇 more convenient. In each of the above embodiments, the change in the amount of sensing is used to determine whether the touch object is finely controlled on the φ plate to recognize various gesture operations on the sugar panel, in addition to avoiding noise interference and causing false positives. The problem can be improved, because the operation is not accurate, resulting in the disadvantage that the panel is not recognized, and the convenience of use is increased.
