Drag the touch method and its control module. [Prior Art] At present, the software commonly used on computers mostly uses a graphical user interface (GUI) to present its window image. The advantage is that the user can cooperate with the computer to install, for example, a mouse device and a track. The ball I is positioned as a p〇inting device, and as long as the pointing tool moves in all directions on a plane, a cursor can be displayed on the computer screen correspondingly to move on the window screen correspondingly. And select or perform various actions on various options on the screen of the computer screen. Since this method is a human-oriented visual control method, this simple method is also commonly applied to various electronic products with window software. Take the mouse as an example to illustrate the function of the pointing tool. When using the mouse, just move the mouse to where it is, and then move the cursor to where it is, and then on the screen of the screen, for example, buttons, reels, etc. Press the mouse button to execute the command, for example, the button on the mouse is continuously pressed. Generally, the system is preset to the left mouse button, and double-click (D〇ub) e cncking), for example, execution can be completed. Press the Zhao function, or drag the scroll to scroll the reel. In addition to the commonly used pointing device such as a mouse device and a trackball device, a similar operation is performed by using a touch device pad or a touch panel (t_h 5 10 15 20 1270819 panel). The current electronic products are gradually moving towards a short, thin and light direction, and the trend that notebook computers have gradually replaced desktop computers seems to make small touch devices or touch panels that can be combined with electronic products to be applied. The range of relative increase is less than S. ^ As shown in Fig. 1 'to open the general window screen 91 to read the article as an example', the window screen 91 has its side on the side and the τ side - the first reel 92 along the axis of the axis and a second along the axis of the axis Reel %, when the content of the article is too long, the user can touch the finger device or other object to touch the 35 device (not shown) or the touch device to drag the good-segment distance to drive the cursor to move the first -, The position of the second reels 92, 93 is such that the volume _(10) is out, so that the files in the window 9! can be moved up, down or left and right, ie: the entire article is not limited to the window. The size of the screen 91. As shown in FIG. 2, the identification method of the trolling gesture on the known touch device is proposed in U.S. Patent No. 14,067, firstly, the first occurrence of the touch signal 8〇1 on the skirt. Long stay time ^ 'McCow time value comparison' If the first occurrence of the dwell time length is at the time of the Mickey time m control signal · 屮珣B elbow elbow once and the second occurrence of the touch signal 8〇1 When the second reference time value is compared between the materials, between the materials... In the second table test 2:, the output control signal 802 is maintained, and the value of the temple is owed to the ...t7p, the brother one person The dwell time that appears, and the X and γ position of the output object on the touch device are shown in Figure 1, 2, and the first distance of the scroll window 91 is Λ V in I 92 Example: The user should drag a finger or other object on the touch device 5 10 15 1270819 for a distance, and generate a touch signal 8靡1 for the grip gesture of 靡1&& 'After the touch signal 801 starts, the trick signal f, 攸 only 4 t4 starts to generate the control signal 802, and appears in the second time Q outputs with sore Ί object to detect and Y location on the touch device when the stay length k. However, the above-mentioned drag-and-touch method has a disadvantage in that the manner of determining the length of movement of the first reel 92 is determined by the total amount of Y-position information movement of the corresponding gesture, if the user wants— When the second scrolling distance is longer, it is necessary to move a considerable distance on the touch device. Otherwise, it is necessary to make repeated dragging actions on the touch device, but this is likely to cause fatigue in use. [Summary of the Invention] If the user wants to scroll the window screen for a long distance, it is necessary to move a considerable distance on the touch device or to drag back and forth. The disadvantages of the touch method are thus the concept of the present invention. Therefore, an object of the present invention is to provide a method for continuously outputting a control signal to continue scrolling a window or a finger or other object and a touch device even if the finger or other object stops on the touch device after the dragging action. No longer touch, you can stop the scrolling of the window, making it easier for the user to drag and drop the touch method and its control module. The drag and drop touch method of the present invention recognizes the dragging action of an object on the touch device by a control module of the touch device, and provides a control signal generated by the dragging action for a host as a subsequent control function. In use, a first reference time is set in the control module. 20 1270819 The method of dragging and detecting is to detect the occurrence of a dragging action of the object on the touch device $, and start timing at the same time; if the time of staying on the touch device exceeds the time when the three objects move a second time; that is, outputting a control signal indicating the dragging action for the 5; and waiting for the object to move statically and continuously outputting the control signal for use by the host while being still in phase with the touch device, The control signal is stopped when the touch device is not in contact with the touch device. The control module of the present invention is used for recognizing an object in a touch-and-snap action, and corresponding to the control generated by the dragging action, the host is used as a subsequent control function, and the control module is used in the control module. The first reference time, the control module includes an arithmetic unit and a computing unit and a gesture unit of the host. The different units of the 亥 运 彳贞 彳贞 彳贞 彳贞 彳贞 彳贞 彳贞 彳贞 彳贞 彳贞 彳贞 彳贞 彳贞 彳贞 彳贞 彳贞 彳贞 彳贞 彳贞 彳贞 彳贞 彳贞 该 该 该 该 该 该 该 该 该 ° ° ° ° ° ° ° ° ° ° ° ° ° Is generated and terminated after the t-beam; the gesture unit receives the touch signals, and the first touch signals calculate an action of the object appearing on the touch device to identify the object. If the gesture unit determines that the object stays at the touch time for more than the first reference time, the control unit outputs a control signal indicating that the object is used by the host, and the object is stationary and the touch device is In the state of mutual contact, the control signal is continuously outputted until the object is in contact with the touch device, and the control signal is stopped. 5 10 15 1270819 [Embodiment] The foregoing and other technical contents and features of the present invention are better understood in conjunction with one of the following drawings. "...the sweat description of the ... will be clear as shown in Figure 3, which is the control group 13 of the present invention, which is assembled in the touch device! and electrically connected r... Between 10 and 1 , and the control module 13 and the touch panel 10 are electrically connected to each other by -x, 兀U, -Y direction, and the touch panel 1 〇 is capacitive, resistive, electromagnetic, Mo force type, inductive type, surface acoustic wave type, ultrasonic type or optical type, etc. In the preferred implementation, the touch panel (7) is a capacitive type, and the basin can be touched by the side finger 2 on the touch panel 1G. The capacitance of the touch position changes, that is, when the finger 2 touches the touch panel 10, since the surface of the touch panel 10 is an induction matrix, a contact capacitance is generated, and the χ direction processing unit 11 and the Υ direction processing unit 12 continuously track the trajectory of the contact capacitance of the finger 2, and the operation unit ΐ3ι in the control module 13 positions the X and Υ coordinate position parameters of the finger 2 position to calculate the χ and γ direction displacement amounts (MovementMX, ΔΥ) At the same time, the computing unit 131 can also measure that the finger 2 is touched on the touchpad H) and the pressure changes. A touch signal 501 related to the degree of touch pressure is generated. Each touch signal 501 is generated corresponding to the start of the touch panel 10, and is terminated after the end of the occurrence, and the operation unit 131 The detected X, Y direction displacement amounts Δχ, Δγ, and the touch pressure signal 5〇1 are transmitted to the gesture unit 132, and the gesture unit 132 shifts 20 1270819, Δ γ, and touch voltage k唬501 according to the χ and γ directions. The value is used to determine the touch mode of the finger 2, in this example, the drag gesture action, and the control signal 503 corresponding to the gesture is transmitted to the host 3 via the transmission interface M for subsequent use. As shown in FIG. 5, the drag touch method of the present invention firstly does not occur when the touch action of the finger 2 on the touch panel 1 is detected, and the gesture sheet is detected and starts counting, and continues. After the measurement and recording of the dwell time of the finger 2 on the touch panel 10, the positive edge of the waveform of the signal 501 in FIG. 5 (the transient transition between the low level and the high level) refers to the occurrence of the touch action. = "Step 403 'Set a first reference time in the gesture unit 132. Wherein 132 determines that the time when the finger 2 moves on the touchpad exceeds the first reference time Τι, that is, when the finger touches the touchpad 10, the touch action exceeds the first reference time τ], and then, as in the step The letter = '= finger 2 on the touchpad 1 () generated by the amount of displacement 5 〇 2 is more than the parameters, the position and the inside ' can determine the touch action is a drag gesture, if the conditions of steps 403 and 404 are not met Then, if step 4〇5 and the steps are completed, it is determined that the operation is not a drag gesture, and other actions are determined. 20 If the step 403 is satisfied, “When the finger moves on the touch panel 10, the time exceeds the first reference time Τι” The conditions, and the steps and the condition that "the amount of displacement generated by the hand 1 on the touchpad is 5 〇 2 is greater than the reference displacement" is continued, and the step bias is continued, and the click gesture shown in FIG. 5 is performed. (4) The signal is, for example, the control signal is generated from the (4) gesture and is outputted for use by the host 3 after the test time is 1 , indicating that the second action L 503 is a series of pulse signals. 9 5 10 15 20 1270819 ^289 Application Description
