Users only need to move the mouse with visual indicators and click on the action to easily complete the desired The action performed solves the problem that the previous text mode needs to input complicated instructions and causes inconvenience in use. Therefore, the Windows interface has been adopted by Apple Computer and Microsoft (Micr〇s〇ft), becoming the mainstream mode of all operating systems. In electronic devices that use the Windows interface system, such as desktop computers, notebook computers, tablet computers, personal digital assistants (PDAs), etc., the pointing device (p〇intingdevice) has become a basic device. Currently, it is directed to a mouse with an external device, a trackball and a touchpad built on a portable computer system, and a touch panel combined with a wire, among which the mouse is the earliest. The introduction of the pointing device to the mouse as an example to illustrate the function of the pointing device, the mouse can control the electronic == on-screen indicators (P°imer) 'that is where the mouse moves, the indicator is also followed by =, then in the screen Pressing the control button on the target to be executed can command the electronic device. "At present, the 5 5 10 15 20 1252433 5 is also developing towards a short and light size. For example, notebook computers have gradually replaced the shipment of desktop computers, resulting in the gradually becoming smaller pointing devices (such as touch panels). The mainstream of the device. The technology of the touch device generally includes capacitive, resistive, electromagnetic, pressure, inductive, surface acoustic wave, ultrasonic, optical, etc. When an object such as a finger Moving on the touch device, the T indicator can be controlled to move along the direction of the object movement. However, in addition to controlling the movement of the indicator, the pointing device also has the function of issuing an execution command. For example, the operation of the mouse is used as an example to move the indicator. When you want to start the target (such as program, file), you can press the two mouse button (4) Clieking continuously. If the system is preset to the left mouse button, you can select the target and turn it on. However, for example, touch For touch devices such as control boards, more than two control buttons are added below them to replace the left and right keys of the π mouse, or to define an action gesture of the object on the touch device. The signal should be simulated to press the mouse button twice in succession. For example, the touch device is to tap the touch device twice in succession (10), and the target is turned on to replace the mouse. In the U.S. Patent No. 4,671, it is proposed in the U.S. Patent No. 4,671 to determine how to distinguish the F. lsp with the double-click gesture on the touch device (corresponding to the United States). Patent No. MM, 671: In the first time, the length of time t1S| of the first appearance of the object on the touch device (ie, the time when the object appears in the first touch of the touch device 昧 ^ ^ times) ) Compared with a multi-test time value, if the first ^, brother < time length t] 9 is less than the first test time value, then the mm is not detected in the second time in the first time - When the view is seen, the first signal is terminated, 5 1252433. In other words, the time interval between the first and second occurrences needs to be smaller than the second reference time value; secondly, the second occurrence time length h and the third reference time Value comparison, if the second occurrence time length is less than the third When the test value is 5 10 15 , the first signal is terminated and a second signal 12 is generated, so that two signals 'Tiger 11, 12 can be outputted to simulate the output of the signal generated by continuously pressing the mouse button twice. The conventional method can achieve the purpose of recognizing the double-click gesture. However, in the conventional method, the time length ti9 of the first occurrence, the time interval t2 between the two occurrences, and the length of time t2丨 of the second occurrence are respectively Corresponding reference time value for judgment 'much makes the judgment more complicated. Moreover, due to the personal difference of the user', the time of each stage of the double-click gesture performed by each person on the touch device may be different, or the same - The duration of each action performed by the user on each double-click gesture may also be different, resulting in a situation in which the conventional method is prone to misjudgment. Moreover, during the use of the touch device, the noise generated by the gate device, or the noise generated by the device itself, or the noise originating from the external environment, may cause a short spike. The first occurrence and the second occurrence of the phenomenon, the conventional method does not limit the time length of the first person and the time interval between the two occurrences, so that it is easy to interfere with the interference caused by noise interference. It is not appropriate, and it is easy to have a misjudgment. In addition, because of the drag and drop ag ag ag) material potential (four) two cut hits and reduce the hit when dragging, due to the conventional method to go to the mountain brother - a person in the 未 将 将 将 累计 累计 累计 累计The amount is included in the judgment 'the situation that is easily confused with the Μ gesture and misjudged. 0 20 1252433 SUMMARY OF THE INVENTION The main object of the present invention is to compare the value of the method using the second action of each action == double-click gesture The judgment is more concise and ok; the other effect of the present invention is: 裎* controller, which requires each action 2; the method value of the gesture to effectively avoid the misjudgment caused by noise . In the corresponding reference - the purpose is to provide - ίο 1,5 method and controller 'requires the second occurrence of the _ to ==: the corresponding parameter values, in order to achieve accurate judgment. The method of generating a double-click gesture on the square control device of the present invention includes the following steps: the gesture is to detect a first occurrence of an object on the touch device, and the object is measured. On the touch device - the second occurrence of I and if the first occurrence of the time is long, a reed, n traditional u. And ^ first " the time when the person appears long = the end of the current and the first The sum of the time intervals between the beginnings of the second occurrence is less than a first-reference time value, that is, the generation - the first signal and the first occurrence of the second signal. The above and other technical contents, features and effects of the present invention will become apparent from the following detailed description of the preferred embodiments. First, it is explained that the method of recognizing the double tap gesture of the present invention is used in a touch device. In order to say the purpose of the sun, the moon, and the moon, in the present embodiment, the capacitor 20 1252433 type touch device is selected for illustration. 5 10 15 as shown in FIG. 2, the capacitive touch device 2 includes at least one touch panel 2, one and eight X-direction processing units 22, a Y-direction processing unit 23, an arithmetic unit of an operation unit 24, and a displacement unit. 25. A gesture unit 26 and a transmission interface 27. The touch panel 21 has a plurality of wire distributions in the X and Y directions, for example, 16 in the X direction and 12 in the Y direction. Thus, when an electrically conductive object such as a finger ίο touches or approaches the touch panel 21, a change in capacitance value occurs on the touch panel 21, and then the χ, γ direction processing units u, 23 are processed separately. The capacitance values in the γ and γ directions are then passed to the arithmetic unit μ. The π unit 24 will transport the X coordinate value and the γ coordinate value of the contact position of the object. Then, the displacement unit 25 receives the operation result χ and the coordinate value of the operation unit 24, and calculates the relative displacement Dx, DY (refer to the touch pressure signal) of the object on the touch panel 21, and then transmits it to the gesture unit % and The transmission interface is so smart that the calculation results Dx and Dy can be transmitted to a host through the transmission interface 27 (-3) for the host 3 to control the movement of its indicators on the screen. The host 3 can be a personal computer, a notebook computer, and a personal digital processing. Machine (pDA), mobile phone, etc. Here, since the above-mentioned components are not improved features of the present invention and are well-known to those skilled in the art, they are not described here. In addition, the arithmetic module and displacement unit 25 of this example are The gesture unit 26 and the transmission interface 27 are integrated in a controller such as a chip. ° The calculation result %, d of the gesture unit 26 is used to determine whether the object is generated on the touch panel 21 Double-clicking the gesture Y′ and correspondingly outputting a first-signal of the analog-by-two-sliding button is fed to the host computer 3 via the transmission interface 27 to make the system 20 1252433. The technical feature of the present invention is The double-click gesture method is recognized in the gesture unit 26. The gesture unit 26 can implement a method of recognizing a double-click gesture by using a soft body, a body, or a hardware. Furthermore, although the gesture unit 26 of the present example is integrated with the control of the touch device 2 In the present invention, it may be disposed in the host 3 in a soft or hardware manner, and is not limited to the one disclosed in the embodiment. In addition, although the capacitive touch device 2 is taken as an example, the familiar example is familiar. The skilled person knows that the present invention can also be applied to other types of touch devices, such as optical, resistive, electromagnetic, pressure, inductive, surface acoustic wave, ultrasonic, etc., and should not It is limited by the embodiment. The judgment flow of an example of the embodiment is illustrated in Fig. 3 and Fig. 4. In this example, it is assumed that the touch panel 21 is continuously knocked by an object such as a finger 1 Tap twice. For convenience of description 'In the following, the object is represented by the finger 1 。. It should be noted that although the following example illustrates the object with the finger 10 as an example, it is familiar to the skilled person. know, For example, the touch device 2 can detect other types of conductive objects, or can detect multiple conductive objects, and should not be limited by the embodiment. First, in step 41, the touch device 2 detects the finger. 1 is the beginning of the first appearance on the touchpad 21. When the touch device 2 detects the start of the first appearance, the gesture unit 2 will start timing. ' In step 42, it is used to judge ili Then, the conditions for the first occurrence of the knot and the rain condition from the second time value Τι are first achieved. This example assumes that the first reference time value 1 should be β 贞 14 to the double click. Example number - reference time value 5 10 15 20 1252433

During the use of the touchpad 21 of the human B, it is easy to be mistakenly touched by the noise generated by the work itself, or the improper signal originating from the external environment === ^, such as the first, second appearance, and the first blood The time interval between occurrences. Since these improper signals only last for a short time of 10 5 10 15 1252433, in the present embodiment, the time required for each action in steps 45 and n 49 respectively must be greater than the corresponding minimum time value, respectively, to effectively filter out the inappropriate signals. , in order to increase the accuracy of identification. In the =", first judge the first time in the first heart: the fourth time interval of the -4th signal, whether it is greater than a first lifting reference time value T2]. The first minimum lifting reference time value is 21 : (1, (1) The shortest effective time. The first time 21 Gu. After the finger 1G, the first tapping and lifting off the touchpad: the time before the second tap of the hand ^曰1〇 Spacing. The first minimum lifting reference time value T21 in this example ranges from α seconds to 1G microseconds (1_ can be adjusted according to the designer's or the operator's operating habits: If step 45 determines the first-day female car „μ τ time value two hearts = , 2 彡 代表 represents the first time interval Tupl signal f is a valid signal, and thus proceeds to step 46. If step 45 is determined that the first inter-t spacing Tupl is not greater than the first - minimum lifting reference time The value L (τ^ =,) ' means that this first-time lifting signal should be regarded as miscellaneous because the time is too short, so the first occurrence does not really end. So jump back to step 42 to continue detecting the first time. The end of the occurrence. In step 46, determine whether the length of time of the first occurrence is _ whether it is at a first-minimum tap reference time Since the general finger 〇 appears on the touchpad 21 means that the finger 1 () is touched (D_) on the touchpad, = where the finger 1 is placed on the touchpad 21 for the first time The effective time is called the first-minimum tapping reference time value T3. If the length of the first occurrence is determined to be greater than the first minimum enemy attack reference 20 1252433 time value τ31 in step 46 [τ, d°wnl>T31) , means that the first occurrence is valid and then proceeds to step 47. Conversely, if the judgment in step 46 is no (because: the jump means that the first occurrence is noise, it is discarded, the factory is "remaining" A _th occurrence. The day "V" is after the start of the second occurrence, the gesture unit 26 is further used to calculate the cumulative displacement of the second occurrence of the second division. In step 47, it is judged that the face 1Ϊ三纽 is now in the east, the second occurrence of the cumulative Μ 丨 A A A i ^ - Ml and from the first time ι, ο 15 20 which conditions - two conditions: ::47 in the first judgment of the end of the second occurrence, the representative in the first = ΤΤ, indeed detected twice appeared and second The occurrence of the ° ° "2 is less than the reference displacement % (Mdown2 < Ml), then ^ need" in steps 48 and 49 to confirm that the second occurrence is really the end of the blood person appears as a valid signal, you can reach a determination twice Appears as double material and 0 in step 4", determines whether the first time interval TUP2 after the end of the second occurrence is greater than - the second minimum lifting reference time value L. If step 48 determines that the second time interval Tup2 is greater than the first When the minimum value is T22 (TUP1>T22), it means that the second occurrence is true. Then, proceed to step 49. Conversely, if it is determined in step 48 that the second time interval tuf > 2 is not greater than the second minimum lifting reference time value τ (τ , , means that the lifting signal of the second time interval is miscellaneous 2 : ^ T22), s If you don't use it, skip back to step 47 to wait for the second time, the second brother, the mouth, the real 12 1252433, the second signal. In this example, the second minimum lift reference time value □22 can be set to be the same as the first minimum lift reference time value Τ2ί. In step 49, it is judged whether or not the second occurrence time length Td - is greater than a second minimum tap reference time value L. If it is determined in step 49 that the % interval Td_2 of the first person is greater than the second minimum enemy reference time value T32 (Tdown2>T32), then the signal indicating the third occurrence is a valid signal, and then the first occurrence occurs. The length of time T—the first time interval Tupi /, the time length of the first person Td_2 is less than the first reference time value=[(Td_1 + Td_2+Tupi) <Τι] and the second occurrence of the cumulative displacement# -Mdown2 is less than the reference displacement 4 Μι (μ-<μ is small to perform step 50. Otherwise 'if step 49 is judged to be no (I.. The current time is too short and should be noise, so the second appearing signal = Jump back to step 44 to wait for the beginning of the second real occurrence. In this example, the second best hit reference time & can be set to be the same as the first _ maximum hit reference time value D. 31. In step 50, the gesture list The 兀26 outputs the first signal to be fed into the host computer 3 via the transmission interface 27 to inform the host 3 of the double-click gesture generation, simulating the signal that the mouse button 1 is continuously pressed twice. As shown in Fig. 3, this example Signal 51 ” 52, after detecting the second occurrence, and completing the double-click judgment After that, the first signal is different from the conventional identification method, and the first signal is generated immediately after the first and second taps. If the first step occurs, the cumulative displacement amount 吣_2 is determined first. Not less than the reference displacement amount Mi (MwgMJ, means hand: the first _ person taps the touchpad 21 fashion moves on the touchpad 21, because 13 1252433 5 this: can be a dragging gesture, non-double tap gesture, and thus jump To (4) 43, to determine whether it is another gesture. Therefore, avoiding the opportunity to effectively avoid the misunderstanding gesture as a double-click gesture occurs. The reference displacement amount M1 in this example can range from 1 pixel (PiXel) to 10 pixels ( 1 Pi mail ^ H) pixel ), for example, 3 pixels, can also be adjusted according to the designer's needs and user's operating habits. 10 t Step 43 to determine whether it is another gesture Ο Inductively the above, this embodiment is for the double-click gesture formula 1~5: 15 Ding downl > T3 1 Formula 1 Dingdown2 > T32 Formula 2 TUpl>T21 Formula 3 Tupl>T22 Formula 4 (Tdownl+Td〇wn2 + TUp)) Τι Formula 5 20 ^•do wn2 ^ M i Equation 6 1 It should be noted that although the aforementioned step 42 44. Similarly, if step 47 is used, it is first determined that the time from the first occurrence has reached the first reference time i, meaning that the length of the first occurrence is η "η1, the first time interval τ The sum of the time length Td_2 of the second occurrence is not less than the first reference time value, and refers to (Td〇wn] + , 々, q 5 Ifr conditions, however, those skilled in the art are aware that the aforementioned step 42 44. The conditions may also be judged in order, and should not be limited by the present disclosure. According to the above, it is different from the conventional time to judge whether the time of each phase of the action is less than the corresponding reference time value, and the identification of the present invention (4) gesture 2 14 5 10 15 20 1252433 (10) each action time length τ "ηί, Td_2, And summing up to determine whether it is based on the first-reference time value τ] (refer to formula 5), in order to achieve a more concise and reliable effect. In addition, the present invention requires that each action time length be greater than the corresponding reference value T31. (Refer to the formula υ, τ32 (to test the public =), 7 (refer to the formula 3), τ22 (refer to the formula 4), to the effective _. and the improper signal 'to achieve a more accurate judgment. In the invention, the cumulative displacement Md_2 of the second tap is required to be smaller than the reference displacement M1 (refer to Equation 6), which is different from the (4) gesture, and can effectively avoid the misjudgment and the gesture as a double-click gesture, thereby achieving _ The effect of the above is only the preferred embodiment of the present invention, and it is not possible to limit the present invention to the MM', that is, the simplicity of the patent scope and the contents of the invention description in the present invention.
