Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and control benefit for identifying a drag gesture, and more particularly to a method and control for recognizing a drag gesture on a touch device. In order to recognize the drag gesture on the touch device, a drag and drop signal simulating the target of the mouse dragging is generated. [Prior Art] The Graphical User Interface (GUI) was first introduced by the Quanro j\RC Research and Development Program. It is equipped with a pointing device (such as sliding to use the user only by visually). The indicator moves the mouse and adds the action Fp to easily complete the action that you want to perform. It solves the problem of inconvenient use caused by the input of the traditional text and the complicated instructions. Therefore, the Windows interface has been connected to the computer and Microsoft ( Adopted by Microsoft) to become the mainstream mode of all operating systems. In the application of Windows interface system electronic devices, such as desktop computers, notebook computers, tablet computers, personal digital assistants (PDA^, etc., pointing devices (p〇inting Heart (6)) has become the basic equipment. / The current pointing device includes an external device mouse and (4) a trackball trackpad on the portable computer system (t〇uch (4), and a touch panel combined with the screen) Etc., the mouse is the earliest pointing device. Take the mouse as an example to illustrate the function of the pointing device, the mouse can control the electronic device, the indicator on the screen (pointer ) 'Where the mouse moves, the indicator also moves: where' then press the control button on the screen to execute the target on the screen. _ " ^... and the electronic device design The development of short, light and thin, such as pen-cutting, has gradually replaced the shipment of desktop computers 5 10 15 1248015, resulting in a small touch device (such as a touchpad) gradually becoming a mainstream. - The technology of the uranium touch panel generally includes capacitive, resistive, _, ., ,, electromagnetic, rigid, inductive, surface acoustic wave, ultrasonic, optical, etc. when such as a finger The object can be moved on the touchpad to control the movement of the finger along the object=moving direction. However, in addition to the control finger=, the pointing device also needs to have the function of issuing the command. The operation is as an example: When the indicator moves to the target to be moved (such as the program 'file, picture'), you can drag the mouse button (such as the left button) and move the mouse to drag the target. To other locations. 'However, to For a touch device such as a touchpad, more than two control buttons are added below the mouse to replace the left and right buttons of the mouse, or some action gesture of the object on the touch device is defined to move the target. - and generate a continuous button press of the mouse button, so that the target can be dragged to other positions. The body touch & device is _ drag gesture to simulate the movement of the mouse dragging the "method" Performing a tap on the touch device and performing a move (m〇ve_) gesture to move the target object. The method of recognizing the touch is proposed in Japanese Patent No. 6,414,671. The conventional method of loading the drag on f. In conjunction with the map, first compare the length of the object to the touch--, the length of time (that is, the first time the object appears on the touch device) blood ^ ^ ^ Μ and a first reference time value If the length of time t4 of the first occurrence is less than the value between 箆1 and 麦麦考%, then a drag 矾唬11 is generated; then, the time interval between the first f. A second reference time value comparison, if the time interval t5 is less than the threshold value of the second reference time 20 5 10 15 20 1248015, then the drag signal 〗 〖 is maintained to repeatedly generate x, Yf signals. "The current time is long". The inner feather knows that the method can achieve the purpose of recognizing the drag and the gesture. However, due to: '中, the length of the first appearance will be t4 and the 1st disc will be the second sub-sewer. Corresponding reference time is more complicated, and repeats 'money' in the length of time of the second occurrence, resulting in a more complicated design. (4) Because of the difference in the user's personal connection, the time for each person to perform the drag gesture on the touch device may vary, and the length of time for each action of the same user to perform the gesture is also It may be different, resulting in a situation where the conventional method is prone to misjudgment. Moreover, in the use of the touch device, it is easy to be accidentally touched, or the noise generated by the touch device itself or the noise originating from the external environment interferes, so that a short spike is generated. The first occurrence of the first occurrence, the interval between the first occurrence and the second occurrence of the surge, and the second occurrence of the surge, the length of the first method does not occur for the first time. The time interval between the two occurrences is limited by the minimum time, so that it is easy to judge the signal generated by the noise interference, and it is easy to have a misjudgment. SUMMARY OF THE INVENTION The main purpose of the present invention is to provide a method for recognizing a gesture of awkwardness and a controller to use the time sum of each action to compare with the reference time value to achieve a more simple and reliable judgment. Another object of the present invention is to provide a method for identifying a gesture of dragging and controlling the time required for each action to be greater than a corresponding time value of 6 5 10 15 20 1248015 'to effectively avoid misjudgment due to noise. occur. Another object of the present invention is to provide a method and a controller for recognizing a drag gesture, which can compare the cumulative displacement amount during the second occurrence period with a clip displacement amount to determine whether the shot is a drag gesture or not. For the purpose of accurate judgment. In the method for recognizing a gesture of the present invention, the gesture is generated on a touch device, and the method includes the following steps: detecting a first occurrence of an object on the touch panel; detecting the object a second occurrence on the touchpad; and "if the time of the first occurrence is longer, and the sum of the time intervals between the first occurrence and the beginning of the second occurrence is less than - the first - reference time value, and if one of the following two conditions is met, then (A) if the first occurrence of the length of time, the first occurrence of the knot and the second occurrence The sum of the time interval between the beginning and the length of the second occurrence is not less than the reference time value; and (B) if the cumulative displacement during the second occurrence period is not less than the shift amount. MODE FOR CARRYING OUT THE INVENTION The foregoing and other technical contents of the present invention will be apparent from the following detailed description of the preferred embodiments. First, the method for recognizing the drag gesture of the present invention is explained.

In the touch device. For the purpose of today's 'A Xi θ' brother, in this embodiment

Features and functions, in the description, can be used for a capacitor 7 5 10 15 1248015 type touch device for illustration. For example, the capacitive touch device 2 has a X-direction processing unit 29 攸-single θ Υ direction processing unit 23, a transport tube early 24 and a displacement unit are transported to the touch panel 2 Then, the _ power generation valley value changes, and then, the χ, γ directions 22, 23 respectively process the X, γ square ~ 凡, the time-direction of the pen value is passed to the arithmetic unit 24 early 70 24 will calculate the object according to this The coordinate value of the contact position and the value of the disk holder. Then, the displacement unit 25 receives the operation result of the operation unit 24, and calculates the relative displacement of the object on the touch panel 21 accordingly.

After Dy (referred to as a touch signal), it is passed to the gesture unit 26 and the transmission interface π. Thus, the compute nodes S Dx, Dy can be transmitted via the transport interface 27 to a host gamma 3 ' for the host 3 to control the movement of its indicators on the screen. The host computer 3 can be a personal computer, a notebook computer, a personal digital processor (pDA, mobile phone, etc.). Here, since the aforementioned components are not an improved feature of the present case and are familiar to those skilled in the art, they are not here. In addition, the arithmetic unit 24, the displacement unit 25, the gesture unit %, and the transmission interface 27 of this example are integrated in a controller such as a chip. The gesture unit 26 receives the calculation results Dx, Dy of the displacement unit 24 to determine Whether the object has an action corresponding to the drag gesture on the touch panel 21 and correspondingly outputs a drag button for simulating the mouse button and moving the mouse when determining the drag gesture (the drag signal is a plurality of consecutive signals) The cover 20 l248〇i5 package is fed to the host 3 via the transmission interface 27 for corresponding control of the cursor. The technical feature of the present invention is: the method for recognizing the drag gesture by the gesture unit 26. The method can be soft, scorpion, or hard. The body mode is set in the gesture unit 26. In addition, although the gesture unit 26 of the present example is integrated in the controller of the touch device 2, it can also be soft. Or the hardware is not limited to the one disclosed in the embodiment. In addition, although the capacitive touch device 2 is taken as an example, the skilled person knows that The invention can also be applied to other types of touch panel devices, such as optical, resistive, inductive, pressure, electromagnetic, surface acoustic wave, ultrasonic, etc., and should not be limited by this. The embodiment of the present invention is described with reference to Fig. 3. In this example, it is assumed that the touch panel 21 is tapped by an object such as the finger 10 (_ twice. The description is convenient. In the following, the object is represented by the finger 1G. In addition, although in this example, an object of the finger 1〇 is used for explanation, but the skilled person knows that the touch panel 21 can also sense a plurality of objects. It should not be limited by the example. First, in step 41, the touch device 2 detects the start of the first occurrence of the finger 1 on the touch panel 21, that is, the start of the first tap. At the same time, the device 2 will start counting the finger 1G on the touch panel 21. In this example, if it is assumed that the drag gesture is a first reference time value, the start of the two occurrences is detected. The range of the first reference time value τ丨 in this example can be set to In 100 microseconds to 1 〇〇〇 microseconds (10) (four) ding ^ 诵 (four), can be adjusted according to the needs of the designer or the user's operating habits. 9 5 10 15 20 !248〇15 and then 'in step 42, touch The finger on the device board 21 is 〇1, and the two conditions in the touch control ^~~~, if it is determined in step 42, it is determined that the first time has not reached the first reference time value, . It is possible that the first reference time 胄τ has already appeared for the first time, because step 44 is continued. Conversely, if the Niu Zan 4 has a second occurrence, then the first reference time value is determined to determine that the counting time has been Arrival occurs and the time length T1 in the first time value T1 is only exceeded, and the non-drag, gesture, and thus the gesture unit 26: the time value is determined to determine whether it is another gesture.兀%Execution Step 43 Board 2ΓΙ: Touch: Device 2 continues to judge which part of the secret towel - condition first (four) into. · The second occurrence of the breakout has begun. The Xian 44 towel may be judged twice. The tea test time value is within. If the step 44 is first judged: wide gesture, proceed to step 45. ‘Can confirm non-(4) gestures When arriving at the first – reference time value D) Other gestures. Then, the process jumps to step 43 to determine whether it is determined in step 44 that the touch device 2 has already started when the previous two appearances have begun. - on the second and second; on the touchpad 21 (four) continued time), - between the appearance of the person 1 spacing τ, ιη1 (refer to 10 1248015 between the finger 10 after the first tap and lifted off the trackpad 21, the length of time until the second tap of the finger 10). The touch panel 21 is easily misunderstood during use, or is caused by noise generated by the operation of the touch panel 21 itself or by noise from the external environment. The time interval between the appearance of one occurrence, the second occurrence, and the occurrence of two occurrences. Since these improper signals only last for a short time in many times, in this embodiment, the duration of each action is required to be greater than the corresponding minimum reference time value, respectively, to effectively filter out the inappropriate signals, thereby increasing the accuracy of the identification. . Thus, in step 45, it is determined whether the first time interval Tupl between the first and second occurrences is greater than a first minimum lifting reference time 2]. Here, the first dare to mention the reference time value "the shortest effective time of the UP 川 提起 提起 (UP) and then the lower limit. In this example - the minimum lifting reference time value □ 2 can be set to about 1 micro Seconds ~ 10 microseconds (1ms Kenting 1〇m〇' can be adjusted according to the designer's needs or user's operating habits. If the step = the first time heart Tup] is not greater than the first minimum lifting reference time ^ ^ ( Tup】f21) means the first time between the first time and the second time: the time interval:: is too short, so the signal of the first time interval is judged 4: 1:7. End, and jump back to step (4). If the reference time value Τ2] (Τ >τ, R main_generous, and younger T^ υρ1>Τ2]) in the first time of the Hungarian break in step 45, it means The first inter-employment interval up] is valid, then proceed to step 46. In / 46, 'Judge the first appearance of the generous "One-on-one slamming ancient burning 1 down" 疋 No. Reference time value Ding 3]. Here, the first minimum tap 20 1248015 = time value T31 refers to the most remaining on the touchpad 21 There is an It. If the length of the first occurrence of the first occurrence is determined in step 46, the reference time value T3i(Td_>T3i)Bf means that the signal appearing is a valid signal and continues. Step 47. Conversely, if the length of time T of the first occurrence is judged in step 46, and the value is not greater than the value of the first test time T "T-), it means that the first time sees: noise, so discarding is not needed. Jump back to step 41 to re-detect the first ίο 15 20 compliant. The scope of the first - the most money hits the difficult τ3] & the juice is adjusted for the user or the user's operating habits. In ^Step 47_ ' means the length of the second occurrence of the second time - the time interval, the feeding ^ 10 touch the touchpad 2 " the momentum is nothing more than the finger on the touchpad 21 ... heart" In the long case, or in the finger 10 case, the time gate W t shift is larger than A, so the implementation: = - condition is first achieved. The calculation of the gesture single life D "10 o'clock, the displacement unit 25 is used to produce one Χ, to calculate the second occurrence of the cumulative displacement twice to first detect the end of the second occurrence, can be, the first appearance of the constructive and the second to the current light hand 1]: trace ^ or The requirements are imposed to increase the reliability of _. Therefore, ^ is a good gesture, to ^^ out, ^47 towel, at the same time judge _ test 12 5 10 15 20 1248015 when the second time is raised „from Tup2. At this time, if the second time interval Tup2 is confirmed When the length of time when the second occurrence is a valid signal, it means that there are two complete occurrences in the first reference time value T #女^^值τ丨[(TdownI +

Tdown2 + Tupl) <Ti] and the first - + mountain is not the eye, ... brother - the person appears again ^ dragging gestures. At the end, following (4) "8, 49, first determine whether the second time interval Tup2 and the second time length TdQW „2 are valid signals.

In step AS, it is judged whether or not the second time interval TUP2 is greater than a first: minimum lifting time value T22. The second minimum lifting reference time value Τα of this example can be set to be about 1 microsecond, and the microsecond (lmgT2S Γΐυ* is adjusted according to the designer f or the user's operating habit. If the step:, the second time When 13T- is greater than the second minimum lifting reference time value and two til, it represents that 15% of the second time is a valid signal to: continue the judgment of step 49. If the determination in step 49 is no (Tu^T22) The signal of the second time interval Tup2 is only noise, so the value is used; and it is used to jump back to step 47. In this example, the first minimum lifting reference time 2 is set to be the same as the second minimum lifting reference time value. More than 3 steps most 49 / 'determine the second occurrence time length Td_2 whether the 'first-minimum tap reference time value T32. If the τ first time length τ "η2" is determined in step 49, the second minimum tap reference is When the time value is 32 (d〇'vn2&gt;T32), the second number can be determined, and then it can be inferred that ... U "whether the machine is a valid message or not f: thus jump to step 43' to judge ~, his gesture. Conversely, if step 49 is used, it is judged that the second occurrence of 13 1248015 τ/= degrees The second most money hit reference time value t32 (back to ^ 4Γ), the meaning of the second occurrence of noise for the discarding and discarding, skip, to continue to detect whether the second appearance of the brother has begun. This example 5 10 15 20 fell The range of the reference time value Τ32 can be adjusted according to the designer's needs or the user's first; ': and 'the second minimum tap reference can be set to the same as the small tap reference time value T31. Judging that 筮h Γ, ' can be inferred that two occurrences are dragging $ gestures, so step 执行 is performed first to determine whether the second occurrence is a valid signal.

In the big 2 step Γ 5G, it is judged whether the second occurrence time length Td_ is W or not the minimum tap reference time value T32. If step 5Q, the length of time U appearing at the second minimum tapping reference time value T / "n2 &gt; T32) means that the second occurrence is a valid signal, and the length of time: τ "η1 The first interval Tup between the first and second occurrences, and the second occurrence time length Tdewn2 are not small: reference time value T, [(Td_, + Td_2+Tupi) 4], thus the gesture The early 26 generates a drag signal 'to be fed into the host 3 via the transmission interface 27 to inform the host 3 of the generation of the drag gesture, simulating the drag signal generated by the mouse button being continuously pressed and privately moved. If in step 5, it is judged that the second inter-temple length Td() wn2 is not greater than the second minimum tap reference time value D3 (TdowuST32), the second occurrence is noise, but since the second The first reference time value τ has been reached after the start of one occurrence, so skip to step 43^ to determine if it is another gesture.
