Description

200945126 IX. Description of the Invention: [Technical Field] The present invention relates to a method for simulating the movement of a mouse by pressing M, and a controller thereof, in particular, a method for identifying click, double-click and drag action and touch Controller of the device. [Prior Art] The graphical user interface (Graphical User Interface, g ❹ ❹ is the program operation interface first introduced by the Quantum PARC Lab, which can be used with a pointing device (Pointing Deviee 'such as a mouse). It is only necessary to move the mouse with a visual indicator and click on the action to easily complete the action that you want to perform, effectively solving the inconvenience of inputting complicated characters in the previous text mode. Therefore, the window interface has been Apple. Computers and Microsoft (Microsoft) are the mainstream mode of all operating systems. On the electronic devices that use the Windows interface system, such as desktop computers, pens, computers, tablets, personal digital assistants (p(10)(10), PDA) Etc., the pointing device has become a basic device. The pointing device currently includes a mouse for the external device, a trackball and a touchpad built on the portable computer system (τ(四)h Pad), and a touch panel combined with the screen (Touch) Panel), in which the mouse is the earliest launching device. Take the mouse as an example to illustrate the function of the pointing device, the mouse can be controlled The indicator on the screen of the electronic device (P〇inter), where the mouse moves to the 7 indicator, also moves to where it is. Then, on the screen, press the control button on the screen to execute the electronic device. Directive. However, the design of the electronic device is moving towards a short and light size. For example, notebook computers have been replaced by 200945126. • The replacement of desktop computers has gradually replaced small-sized touch devices (such as touch panels). The trend of pointing devices is mainstream. Currently, the technology of touch devices generally includes capacitive, resistive, electromagnetic, pressure, inductive, surface acoustic wave, ultrasonic, optical, etc., and when objects such as fingers Moving on the touch device, the indicator can be moved in the direction of moving the object. However, in addition to controlling the movement of the indicator, the pointing device also has the function of issuing an execution command. Taking the operation of the mouse as an example, when the indicator moves to If you want to start the target ( © program, file), if you press the mouse button (Clicking, the system defaults to the left mouse button), you can select the target. If you press the double button twice (Double Clicking), you can select the target and turn it on. If you keep pressing the mouse button (such as the left button) and move the mouse, you can drag the target to another location. However, in the case of a touch device such as a touch panel, an action gesture of the object on the touch device can be defined to achieve the same purpose as the operation of the mouse. Referring to FIGS. 1A to 1C, a The touch device simulates a mouse click, a double click and a drag action, respectively, such as US Patent Publication No. US6380931 "OBJECT POSITION DETECTOR WITH EDGE MOTION FEATURE AND GESTURE RECOGNITION" and US6414671 "OBJECT POSITION DETECTOR WITH EDGE MOTION FEATURE AND GESTURE RECOGNITION As shown, a plurality of timers are used to calculate the complex time interval of an object appearing on a touch device, and the click, double click, and drag actions are calculated using the time intervals. In the case of the click action program of FIG. 1A, the time interval TdQWn needs to be smaller than a 200945126-maximum reference time interval Tmu. In the case of the double-click action program of Figure 1B

Time interval T

Do wn- Ϊ need / J, at the first maximum reference time interval Tmau, the time interval Tup_ 1 needs to be less than a second maximum reference time interval Tmax_2, and the time interval T down-2 needs to be less than a third maximum reference time interval Tmax_3 . In the case of the drag operation procedure of Fig. 1C, the time interval Thwnd needs to be smaller than the first maximum reference time interval Tmax l, and the time interval Tup" needs to be smaller than the second maximum reference time interval Tmax_2. However, these conventional inventions have complicated logic circuit construction costs because of the complexity and complexity of the combination and comparison of time intervals. In addition, since the personal differences of the users are different, the time interval of each stage of performing double-click and drag gestures on the touch device may be different, which may cause a misunderstanding of the conventional method. Referring to Figures 2A-2C, another conventional touch device simulates a mouse click, double click, and drag action, as described in U.S. Patent Publication No. US7180506, respectively.

METHOD FOR IDENTIFYING A MOVEMENT OF SINGLE TAP ON A TOUCH DEVICE", US7190356 "METHOD AND CONTROLLER FOR IDENTIFYING DOUBLE TAP ® GESTURES" and US7184031 "METHOD AND CONTROLLER FOR IDENTIFYING A DRAG GESTURE", these conventional inventions utilize a detection The time interval Tdetect analyzes the occurrence and end of the waveform of the touch signal when the object touches a touch device in the detection time interval τ detect to correspondingly generate an operation signal representing the click, double click and drag operation. The detection time interval Tdetect is the same length of time. Due to the simple judgment rule of the prior art, the conventional invention effectively solves the shortcomings of the prior art judgment method, but it is also because Detection time is not fast enough from 200945126

After Tdetect, the click, double click, and drag actions are performed to reflect the user's actions. As mentioned above, in order to improve the time required to perform clicks, double clicks, and drags, and still maintain simpler rules to reduce the cost of logic construction, it is necessary to find a solution.

That is, when the contact detecting unit 13 detects the pressing, a waveform of the touch pressure signal 'the first-time interval 如图ι shown in FIG. 5 and the second time interval as shown in FIG. 6 and FIG. 7 are generated. The waveform of T2. That is, in the present invention, the time lengths of the first time interval T1 and the second time interval D2 are not calculated, but only the waveform changes of the finger touches in the first time interval T1 and the second time interval T2 are calculated. In the present invention, the operation of the contact detecting unit 13 is prevented by other noise filtering methods and algorithms. The gesture operation unit 14 is connected to the coordinate calculation unit 12 and the contact detection unit 13. The gesture operation unit 14 is mainly (d) based on the result detected by the contact unit 13 200945126 • 13 and supplemented by the gesture operation unit 14 The judgment logic 'determines whether the action performed by the user meets the conditions of click, double click, drag and so on. The judging logic uses the timing of the first reference time interval TLB1 and the first reference time interval tLB2' to cooperate with the occurrence and end of the touch signal, and the first reference time interval TLB1 and the second reference time interval TLB2 is calculated by the same timer. "This section will be described in detail below. '

The code list 7G 15 encodes the different signals into handwritten input protocols or standard mouse protocols for host 4 processing, such as the Xishui Standards Association, IBM's ps/2 mouse standard protocol. "De M is due to the coding of the early 15th, serially transmitted to the host 4, to the table, is transferred to the keyboard control Langu _, the earth is the (four) controller (not shown) Or South;, in order to make an interrupt request to the processor of the host 4, r, so that the host 4 can get the step - by-step = 14 200945126 set, execute the action and other necessary parameters, to further move the cursor, the program The actions of the selection or the execution of the program, etc. Referring to Figures 3 and 4, the method for clicking, double-clicking, and dragging the motion identification of the present invention is applicable to the controller 1 described above, and includes the following steps: First, as shown in step 51, the contact detecting unit 13 detects that the action of the object 2 contacting the touch device 3 occurs, and correspondingly generates a touch voltage signal. wherein, as shown in FIG. 5, the first time interval in the touch signal is the positive edge of the waveform (low level transition) The transient state between the high levels refers to the occurrence of the contact action. At the same time, the gesture operation unit 14 controls the timing unit 17 to start timing. Next, as shown in step 52, the gesture operation unit 14 monitors the first reference time. 'contact fu test from TLB1 Whether the operation of the object 2 touching the touch device 3 ends is completed. If not, as shown in step 51, the contact detecting unit 13 re-detects that the object 2 is in contact with the touch device 3, and vice versa. After detecting that the action of the object 2 contacting the touch device 3 is completed, the gesture operation unit 14 calculates the waveform change of the finger touch during the first time interval T1 through the timing unit 17 as shown in step 53 and FIG. 5, and Generating a negative edge of the first time interval T1 waveform as shown in FIG. 5 (the high level transitions to a transient between the low levels), and generates an operation signal 'from the end of the first reference time interval T1bi' to indicate a Then, as shown in step 54, the gesture computing unit 14 determines whether the object 2 is at the second reference time interval according to the result detected by the contact debt detecting unit 13 at the second reference time interval T1B2r. The touch device 3' is contacted for the second time in TlB2, wherein the operation signal indicating the action of the touch start 15 200945126 is maintained in the second reference time interval Tlb2. If the object 2 is not in the second reference time from the TLB2 Double contact with the touch device 3, as in step 55 The operation signal is terminated from the end of the second reference time interval Tlb2 to indicate a touch end action to complete a one-click action. It must be noted that although the gesture operation sheet A 14 i^ operates a signal to indicate a click Action, but the gesture operation unit 14 is to detect the first reference Ο

In the TLB1 and the second reference time interval TLB2, all the actions of the object 2 contacting the touch device 3 are used as the basis for the overall judgment. Therefore, if the second reference time interval, the inner 'contact detection unit 13 integrates other touches. The pressure signal (YES in step 54) changes the operation signal to a double click (step 56) or a drag action (step 57) as described below. As shown in step 56 and FIG. 6, the gesture computing unit 14 determines that the object 2 touches the touch device 3 a second time within the second reference time interval and leaves. Then, the gesture operation unit 14 terminates the operation (4) from the end of the second reference time interval to indicate the end of the strike operation, and generates and ends the other-operation signal to indicate the other-tap start and end actions to complete one. Double click on the action. The detection result of the step 54 is the same as that generated by the time. As shown in step 57 and FIG. 7, the gesture operation unit 14 determines that the object 2 touches the touch for the second time from the second reference time. The device 3 does not leave yet (not cut away from the T1B2 at the second reference), and the LB2 bundle generates a continuous operation signal from the second reference until the second contact of the object 2 is detected. The operation signal is terminated after the operation of the device ends, and a drag operation is completed at 16 200945126. In summary, the present invention has the following advantages: Compared with the prior art, the present invention does not need to set a multi-array timer to make the judgment condition simpler, and therefore the corresponding circuit design is less complicated, thereby effectively reducing the manufacturing cost. ❹ 〇 〇 〇 〇 〇 〇 , , , , , , 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 〇 τ τ τ τ τ τ τ τ τ τ τ τ τ τ τ τ τ τ time. 2.
