Abstract

A single-click, double-click and drag action identification method and a controller of a touch device are mainly used for detecting the occurrence of an action of contacting an object with the touch device, starting timing, detecting whether the object contacts the touch device and leaves within a first reference time, and if not, starting and stopping an operation signal from the end of a second reference time to represent a touch ending action so as to finish the single-click action. If the object is detected to contact the touch device for the second time and leave within the second reference time, the operation signal is ended from the end of the second reference time to represent the touch ending action, and another operation signal is generated and ended to represent another touch starting action and another touch ending action, so that the double-click action is completed. And when the object is detected to touch the touch device for the second time but the second touch action is not finished temporarily, generating a continuous operation signal from the end of the second reference time, and terminating the operation signal until the end of the action of detecting the object to touch the touch device for the second time is detected, thereby finishing the dragging action.

Description

Single click, double click and drag action recognition method and controller of touch device

technical field

The invention relates to an action recognition method for simulating mouse buttons and a controller thereof, in particular to a single-click, double-click and drag action recognition method and a controller for a touch device.

Background technique

Windows GUI (Graphical User Interface, GUI) is the first program operation interface launched by PARC Research Office. It can be used with a pointing device (pointing device, such as a mouse). Users only need to move the mouse with a visual pointer to move Click on the action, you can easily complete the action you want to execute, effectively solving the inconvenience caused by the need to input complicated commands in the previous text mode. Therefore, the window interface has been adopted by Apple Computer and Microsoft (Microsoft), and has become the mainstream mode of all operating systems. On electronic devices using the window interface system, such as desktop computers, notebook computers, tablet computers, personal digital assistants (Personal Digital Assistant, PDA), etc., the pointing device has become a basic configuration.

At present, pointing devices include a mouse of an external device, a trackball and a touch pad (Touch Pad) built in a portable computer system, and a touch panel (Touch Panel) combined with a screen, etc., wherein 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 pointer (Pointer) on the screen of the electronic device, that is, where the mouse moves, the pointer also moves there, and then press the control on the target to be executed on the screen By pressing the button, an execution command can be issued to the electronic device. However, the design of the current electronic equipment is becoming smaller and thinner. For example, notebook computers have gradually replaced desktop computers in sales, so that small touch devices (such as touchpads) gradually become the mainstream of pointing devices.

Current touch device technologies generally include capacitive, resistive, electromagnetic, pressure, inductive, surface acoustic wave, ultrasonic, optical, and so on. And when an object such as a finger moves on the touch device, the pointer can be controlled to move along the moving direction of the object. However, in addition to controlling the movement of the pointer, the pointing device also has the function of issuing instructions for execution.

Take the operation of the mouse as an example, when the pointer moves to the target to be started (such as a program, file), if you click the mouse button once (Clicking, generally the system defaults to the left mouse button), you can select the target; Clicking the mouse button (Double Clicking) selects the target and makes it open. If you keep pressing the mouse button (such as the left button) and move the mouse, you can drag (Drag) the target to another location. However, for a touch device such as a touch pad, certain gestures of an object on the touch device can be defined to achieve the same purpose as that of operating a mouse.

Referring to Figures 1, 2, and 3, the existing touch devices simulate mouse click, double-click, and drag actions, such as US Patent No. US6380931 "OBJECT POSITION DETECTOR WITH EDGE MOTION FEATURE AND GESTURE RECOGNITION" and US6414671 "OBJECT POSITION DETECTOR As shown in WITH EDGE MOTION FEATURE AND GESTURE RECOGNITION", multiple timers are used to calculate the multiple time intervals of an object appearing on a touch device, and these time intervals are used to calculate the click, double-click and drag actions. In the case of the single-click action program in FIG. 1 , the time T _down needs to be less than the first maximum reference time T _{max — 1} . In the case of the double-click action program shown in Figure 2, the time T _down-1 needs to be less than the first maximum reference time T _{max_1} , the time T _up-1 needs to be less than the second maximum reference time T _{max_2} , and the time T _down-2 needs to be less than the third maximum reference time T _{max_3} . In the case of the drag action program in FIG. 3 , the time T _down-1 must be less than the first maximum reference time T _{max_1} , and the time T _up-1 must be less than the second maximum reference time T _{max_2} . However, in these prior inventions, the manufacturing cost of the logic circuit is relatively high due to the complex combination and comparison relationship of the various time intervals. In addition, due to individual differences among users, there are differences in the time interval between each stage of double-tapping and dragging gestures performed by each person on the touch device, which leads to misjudgment in the existing method.

Referring to Figures 4, 5, and 6, another existing touch device simulates the actions of clicking, double-clicking, and dragging a mouse, such as US Patent No. US7180506 "METHOD FOR IDENTIFYING A MOVEMENT OF SINGLE TAP ON A TOUCH DEVICE", US7190356 As shown in "METHOD AND CONTROLLER FOR IDENTIFYING DOUBLE TAPGESTURES" and US7184031 "METHOD AND CONTROLLER FOR IDENTIFYING A DRAG GESTURE", these existing inventions use the detection time T _detect to analyze when an object touches a touch device during the detection time T _detect When the waveform of the trigger signal occurs and ends, the operation signal is correspondingly generated to represent the actions of clicking, double-clicking and dragging. Wherein, the detection time T _detect is the same time length. Due to the use of simple judgment rules compared with the previous prior art, these existing inventions effectively solve the comparatively complicated shortcomings of the previous prior art judgment method, but also because the single-click and double-click are only executed after the detection time T _detect The action of dragging and dropping cannot quickly respond to the user's operation.

As mentioned above, in order to improve the response time of the actions of clicking, double-clicking and dragging, and still maintain a simpler judgment rule to reduce the manufacturing cost of the logic circuit, it is necessary to find a solution.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the present invention is described in detail:

Referring to FIG. 4 , a preferred embodiment of the single-click, double-click and drag controller 1 of the present invention is suitable for being installed on an electronic device including a touch-control device 3, and can be used to recognize the action of an object 2 on the touch-control device 3, so as to An operation signal corresponding to this action is sent to the host computer 4 . It should be noted that the touch device 3 may generally refer to capacitive, inductive and other similar touch devices 3 , and in this preferred embodiment, it particularly refers to a capacitive touch device 3 .

The object 2 is used to contact the touch device 3, that is, according to the action of the object 2 on the touch device 3, the controller 1 will send a corresponding operation signal indicating its action to the host 4. Generally, these operation signals can be divided into Coordinate changes, click, double-click, drag, move, scroll, left button, right button, middle button, etc., to further simulate the behavior of the mouse and keyboard. Of course, the object 2 needs to cooperate with the touch device 3 , such as a capacitive touch device 3 , so the object 2 is a human finger or other types of conductors.

Host 4 generally refers to various electronic devices, such as desktop computers, notebook computers, tablet computers, personal digital assistants (Personal Digital Assistant, PDA), mobile phones, remote controls for various electrical appliances, or other devices that can be used with touch devices 3 as input The electronics of the device.

A preferred embodiment of the controller 1 of the touch device includes an analog/digital conversion unit 11 , a coordinate calculation unit 12 , a contact detection unit 13 , a gesture calculation unit 14 , an encoding unit 15 , a transmission interface unit 16 , and a timing unit 17 .

Since the touch device 3 has a plurality of wires distributed in the X and Y directions respectively, when the object 2 touches the touch device 3, the capacitance value of the touch device 3 will change, so the voltage can be measured The amount of change to calculate values such as coordinate values.

The A/D conversion unit 11 is connected to the touch device 3 and can convert different voltages into corresponding digital signals for subsequent processing. After receiving the digital signal from the A/D conversion unit 11, the coordinate calculation unit 12 decodes the digital signal into a corresponding absolute coordinate value (X, Y).

The contact detection unit 13 can detect whether the current touch device 3 is pressed by the object 2, that is, according to the X and Y voltage signals transmitted by the touch device 3, it can detect that the object 2 touches the touch device 3, and then generates a corresponding a trigger signal. That is, when the contact detection unit 13 detects a press, a trigger signal will be generated, such as the waveform at the first time _T1 shown in FIG. 5 and the waveform at the second time _T2 as shown in FIGS. 6 and 7 . That is, the present invention does not calculate the length of the first time _T1 and the second time _T2 , but only calculates the waveform change of the finger touch within the first time _T1 and the second time _T2 , and In the present invention, other low pass filters (Low Pass Filter) and algorithms are used to prevent noise from interfering with the operation of the contact detection unit 13 .

The gesture calculation unit 14 is connected with the coordinate calculation unit 12 and the contact detection unit 13. The gesture calculation unit 14 can mainly judge the user’s Whether the action performed meets the conditions of single click, double click, drag and drop, etc. The judgment logic is to use the first reference time T _LB1 and the second reference time T _LB2 as shown in Figure 5 to match the timing of the trigger signal generation and end, and the first reference time T _LB1 and the second reference time T _LB2 are based on Calculated by the same timer. This part will be described in detail below.

In addition to the discrimination of actions, the gesture calculation unit 14 can also provide relative movement, that is, after multiple sets of absolute coordinate values are sequentially transmitted to the gesture calculation unit 14, the gesture calculation unit 14 can also calculate the difference between different coordinates before and after. The relative movement amount of the object 2 on the touch device 3 , even parameters such as speed, direction, distance, etc., as to whether to transmit the absolute coordinates or the relative movement amount to the host 4 will be determined according to the application requirements on the host 4 .

The encoding unit 15 is connected to the gesture computing unit 14, so it can receive the absolute coordinate signal, the relative movement signal, or the operation signal (including single click, double click, drag and other actions) generated by the gesture computing unit 14 . The encoding unit 15 encodes different signals into handwriting input protocols or standard mouse protocols for the operating system of the host 4 to process, such as Microsoft's mouse standard protocol and IBM's PS/2 mouse standard protocol.

The transmission interface unit 16 is used to transmit the encoded signal of the encoding unit 15 to the host computer 4 in a serial manner. Taking a desktop computer as an example, it is transmitted to the keyboard controller (not shown) or the south bridge chip (not shown in the figure), in order to send an interrupt request (Interrupt Request, IRQ) to the processor in the host 4, so that the host 4 can further obtain necessary parameters such as coordinate position and execution action, to further move the cursor and program An action such as selection or execution of a program.

Referring to Figures 3 and 4, the single-click, double-click and drag action recognition method of the present invention is applicable to the above-mentioned controller 1 and includes the following steps:

First, as shown in step 51 , the contact detection unit 13 detects that the object 2 touches the touch device 3 and generates a trigger signal correspondingly. Wherein, as shown in FIG. 5 , the rising edge of the waveform at the first time _T1 in the trigger signal (the instant when the minimum value changes to the maximum value) refers to the occurrence of the contact action. At the same time, the gesture calculation unit 14 controls the timing unit 17 to start timing.

Next, as shown in step 52 , the gesture calculation unit 14 monitors whether the contact detection unit 13 detects the end of the object 2 touching the touch device 3 within the first reference time T _LB1 . If not, as shown in step 51 , the contact detection unit 13 re-detects the occurrence of the object 2 touching the touch device 3 .

Conversely, if it is detected that the object 2 touches the touch device 3 and the end of the action is detected, then as shown in step 53 and _FIG . The waveform changes, and produces the falling edge of the waveform at the first time _T1 as shown in Figure 5 (the moment when the maximum value changes to the minimum value), and an operation signal is generated from the end of the first reference time T _LB1 , which is used to represent a Tap to start the action.

Then, as shown in step 54, the gesture calculation unit 14 judges whether the object 2 touches the object for the second time within the second reference time T _LB2 according to the result detected by the contact detection unit 13 within the second reference time T _LB2 . The touch device 3 maintains the operation signal representing the touch activation action within the second reference time T _LB2 .

If the object 2 does not touch the touch device 3 for the second time within the second reference time T _LB2 , as shown in step 55, the operation signal is terminated from the end of the second reference time T _LB2 to indicate a touch Click to end the action, thus completing a click action.

It must be noted that although the gesture operation unit 14 sends an operation signal to indicate a click action, the gesture operation unit 14 detects that the object 2 touches the touch device 3 within the first reference time T _LB1 and the second reference time T _LB2 All actions are used as the basis for the overall judgment, so if within the second reference time T _LB2 , the contact detection unit 13 detects other trigger signals (the detection result of step 54 is yes), then the above-mentioned operation signal will be extended and changed to the following Double click (step 56) or drag action (step 57).

As shown in step 56 and FIG. 6 , the gesture calculation unit 14 determines that the object 2 touches the touch device 3 for the second time and leaves within the second reference time T _LB2 . Then, the gesture calculation unit 14 terminates the operation signal from the end of the second reference time T _LB2 to indicate the end of the touch action, and generates and ends another operation signal to indicate the start and end of another touch action, thereby Complete a double-click action.

The detection result of step 54 is another situation that will be generated at that time. As shown in step 57 and _FIG . The device 3 has not left yet (not left before the end of the second reference time T _LB2 ), and generates a continuous operation signal from the end of the second reference time T _LB2 until it detects that the object 2 touches the touch point for the second time. When the action of the control device ends, the operation signal is terminated to complete a dragging action.

In summary, the present invention has the following advantages:

1. Compared with the first prior art, the present invention does not need to set multiple sets of timers, and the judgment conditions are simpler, so the corresponding circuit design is less complicated, and the manufacturing cost is effectively reduced.

2. For single-click action recognition, compared with the single-click action recognition of the second prior art, if the detection time T _detect is the same, the operation signal of the present invention is ahead of the time of the second reference time T _LB2 .

3. For the double-click action recognition, compared with the double-click action recognition of the second prior art, if the detection time T _detect is the same, the present invention outputs the first operation signal in advance, reducing the time for one signal transmission.

4. For the drag motion recognition, compared with the drag motion recognition of the second prior art, if the detection time T _detect is the same, the present invention advances the time of the first reference time T _LB1 . The second, third, and fourth points above all show that the present invention can effectively improve the response speed when operating the touch device 3 .
