Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.
Reference herein to "a plurality" means two or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
According to the scheme, when people use the terminal in daily life, the touch operation is executed in the touch display screen of the terminal, so that the terminal executes the real scene of the response corresponding to the touch operation.
A touch display screen: touch screen, also called touch screen, touch panel, etc., is an inductive liquid crystal display device capable of receiving input signals such as touch, etc., when a graphical button on the screen is touched, the tactile feedback system on the screen can drive various link devices according to a pre-programmed program. Common touch display screens can be resistive touch screens, capacitive touch screens, and surface acoustic wave touch screens.
Reporting the point rate: the method refers to the frequency of sending report point data by the touch display screen and represents the response speed of the touch display screen to touch operation. For example, if the reporting rate of the touch display screen is 100Hz, it means that the touch display screen reports reporting data every 10 ms. The higher the point reporting rate is, the faster the touch response speed of the touch display screen is, and conversely, the lower the point reporting rate is, the slower the touch response speed of the touch display screen is. The touch response speed may also be referred to as the handedness.
With the development of science and technology, more and more terminals appear in people's daily life, and people can work, amusement, study etc. through the terminal. In addition, the application of the touch display screen in the terminal also brings great convenience to the user when using the terminal, and the terminal can receive the trigger signal of the user in the touch display screen through the touch display screen and display a corresponding interface in the terminal according to the trigger signal.
Referring to fig. 1, an interface diagram for performing an operation in a touch display screen according to an exemplary embodiment of the present application is shown. As shown in fig. 1, a terminal 110 is included.
Alternatively, the terminal 110 is a terminal mounted with a touch display screen. For example, the terminal may be a mobile phone, a tablet computer, an e-book reader, smart glasses, a smart watch, an MP3 player (Moving Picture Experts Group Audio Layer III, motion Picture Experts compression standard Audio Layer 3), an MP4 player (Moving Picture Experts Group Audio Layer IV, motion Picture Experts compression standard Audio Layer 4), a notebook computer, a laptop computer, a desktop computer, and the like.
Alternatively, the touch display screen installed in the terminal 110 may be any one of a resistive touch screen, a capacitive touch screen, or a surface acoustic wave touch screen. The user may perform a click operation, a double click operation, a long press operation, a sliding operation (moving operation), a multi-touch operation, etc. in the terminal 110, so that the terminal displays a corresponding interface in the touch display screen.
No matter what operation is performed by a user in the touch display screen, the terminal at least receives two trigger signals, namely a press signal and a lift signal, wherein the press signal can be a signal for touching the touch display screen, and the lift signal can be a signal for canceling touch in the touch display screen. Optionally, the data corresponding to the trigger signal received in the touch display screen is often acquired through the interrupt pin according to a preset period and a preset report rate in the terminal, so that the terminal performs interface display, control operation and the like according to the trigger signal.
When the terminal receives a pressing signal or a lifting signal, due to hardware or software reasons, the time lag of the terminal for receiving the pressing signal or the lifting signal is caused, the time sequence of the pressing signal or the lifting signal received by the terminal is disordered, the pressing signal and the lifting signal acquired by the terminal at a certain time are not paired, and the problem of low accuracy of the terminal in responding to the touch operation in the display screen is caused.
In order to prevent the pressing signal and the lifting signal received by the terminal from being unpaired and improve the accuracy of the terminal in responding to the touch operation in the touch display screen, the application provides the data acquisition method, which can realize the function that the pressing signal and the lifting signal received by the terminal are always paired by determining whether the pressing signal and the lifting signal are paired at each time and then acquiring the lifting signal, thereby improving the accuracy of the terminal in responding to the touch operation in the touch display screen.
Referring to fig. 2, a flowchart of a method for data acquisition according to an exemplary embodiment of the present application is shown. The method can be used in the terminal with the touch display screen shown in fig. 1, and as shown in fig. 2, the data acquisition method can include the following steps.
When the touch display screen of the terminal is touched by a user or an object such as a touch pen, the terminal may receive a touch signal (a pressing signal) through the touch display screen, where the touch signal is the first trigger signal.
Optionally, after receiving the first trigger signal, the terminal generates corresponding first touch data corresponding to the first trigger signal, and acquires the generated first touch data.
Optionally, a register may be preset in the terminal, and one flag bit of the register may be used as the first flag bit to indicate whether the first touch data is acquired. If the terminal acquires the first touch data, the terminal may write a first confirmation value in the first flag bit to indicate that the terminal acquires the first touch data. In a possible implementation manner, the values of the flag bits may be represented by 0 and 1, where 0 may be used as a default value of the first flag bit and 1 may be used as a first confirmation value, and when the terminal acquires the first touch data, the terminal may rewrite the value in the first flag bit from 0 to 1.
And step 204, receiving a second trigger signal, wherein the second trigger signal is a lifting signal detected in the touch display screen according to the unique identifier in the first touch data.
When the user or the object such as the stylus pen leaves from the touch display screen of the terminal in step 201, the touch between the user or the object such as the stylus pen and the touch display screen is released, and the terminal may receive the second trigger signal (the lift-off signal) through the touch display screen. Here, the terminal may associate the second trigger signal with the unique identifier in the first touch data, thereby indicating that the second trigger signal corresponds to the first trigger signal.
Optionally, the unique identifier in the first touch data may be an event number or the like randomly generated according to the first trigger signal, so as to identify the first trigger signal, and in this step, the terminal may also identify the lift-off signal detected in the touch display screen according to the unique identifier in the first touch data.
Optionally, the terminal may further use another flag bit in the preset register as a second flag bit, so as to indicate whether the first touch data corresponds to the first flag bit whose value is the first confirmation value. That is, when the terminal detects the first trigger signal, acquires the first touch data, and writes the first confirmation value in the first flag bit, the terminal may also write the corresponding confirmation value in the second flag bit. For example, the values of the second flag bits may be represented by 0 and 1, where 0 may be used as a default value of the second flag bit and 1 may be used as a written confirmation value, and when the first touch data corresponds to the first flag bit whose value is the first confirmation value, the terminal may rewrite the value of the second flag bit from 0 to 1.
The terminal may determine whether the value of the second flag is equal to the first preset threshold, and if the value of the second flag is equal to the first preset threshold, the terminal may obtain the second touch data according to the second trigger signal. The acquisition of the second touch data is similar to the acquisition of the first touch data, and is not described herein again. It should be noted that the second touch data also includes the unique identifier in the first touch data, that is, the second touch data also needs to be associated or identified by the unique identifier in the first touch data.
Optionally, the register of the second flag bit and the register of the first flag bit may be the same register or different registers.
In summary, by receiving the first trigger signal, the first trigger signal is a pressing signal detected in the touch display screen; acquiring first touch data according to the first trigger signal; writing a first confirmation value in a first zone bit when the first touch data is acquired; receiving a second trigger signal, wherein the second trigger signal is a lifting signal detected in the touch display screen according to the unique identifier in the first touch data; and when the value of the second zone bit is equal to the first preset threshold value, acquiring second touch data according to a second trigger signal. According to the method and the device, the first zone bit can indicate that the terminal acquires the first touch data, the second zone bit can indicate that the first touch data corresponds to the first zone bit with the value of the first confirmation value, and whether the step of acquiring the second touch data is executed or not is determined according to the value of the second zone bit, so that the terminal acquires the touch data of the press signal and the touch data of the lift signal one to one, and the accuracy of the terminal in responding to the touch operation in the touch screen is improved.
Taking the touch display screen as a capacitive touch screen and the only identifier of the terminal in the generated first touch data as a trigger number as an example, the pressing signal and the lifting signal received in the terminal are always paired, so that the accuracy of the terminal in responding to the touch operation in the touch display screen is improved.
Referring to fig. 3, a flowchart of a method for data acquisition according to an exemplary embodiment of the present application is shown. The method can be used in the terminal with the touch display screen shown in fig. 1, and as shown in fig. 3, the data acquisition method can include the following steps.
Optionally, the description of the first trigger signal received in this step may refer to the description in step 201, and is not described herein again.
Optionally, after receiving the first trigger signal, the terminal generates corresponding first touch data corresponding to the first trigger signal, and acquires the generated first touch data. The generated first touch data may include coordinates, a touch area, a touch strength, a trigger number, and the like of the first trigger signal in the touch display screen.
In the capacitive display screen, after the terminal receives the first trigger signal, the terminal can detect a capacitance variation at a touch position in the touch display screen, so as to generate first touch data in the touch display screen, wherein the terminal can also calculate data such as a position, a touch area, touch force and the like of the first trigger signal in the touch display screen according to the capacitance variation at the touch position. For example, the terminal may establish a two-dimensional rectangular coordinate system for the touch display screen in advance, when the terminal receives the first trigger signal, the terminal may acquire a region coordinate of the touch display screen where the capacitance value changes as a coordinate of the first trigger signal, and calculate the touch area of the first trigger signal according to the coordinate of the first trigger signal. The terminal can also calculate the touch force according to the change of the capacitance value.
Optionally, the trigger number may be a trigger number obtained by the terminal according to the coordinate, the touch area, and the touch strength of the first trigger signal in the touch display screen. For example, a first correspondence table is stored in the terminal, and the terminal may query the first correspondence table through the obtained coordinate, touch area, and touch strength of the first trigger signal in the touch display screen, so as to obtain the trigger number corresponding to the first trigger signal this time.
In a possible implementation manner, the terminal may obtain the finger number according to the touch area and the touch force, and obtain the finger number as the trigger number. For example, the terminal may number 10 fingers of the user in advance, store the correspondence between each finger number and the touch area and the touch strength, and acquire the corresponding finger number according to the touch area and the touch strength, and use the acquired finger number as the trigger number of the first trigger signal.
In a possible implementation manner, the trigger number may also be a trigger number that is randomly generated by the terminal for the first trigger signal received this time and that can uniquely identify the first trigger signal. For example, after receiving the first trigger signal, the terminal may randomly generate a trigger number, and use the trigger number as the unique identifier of the first trigger signal.
Optionally, the terminal may acquire the data generated by triggering the first trigger signal in the touch display screen, and use the data as the first touch data of the first touch signal.
It should be noted that, in this step, it may also be considered that after the terminal receives the first trigger signal through the touch display screen, the terminal generates and acquires the first touch data for the first touch signal acquired in the touch display screen through a predetermined period or a report rate.
Here, the implementation of the first flag bit may refer to the description in step 203, and is not described herein again.
The terminal may use the acquired first touch data as a trigger condition, and if the first touch data is acquired, write a first confirmation value in the first flag bit. If the first touch data is not acquired, the value of the first flag bit may be maintained as a default value.
In step 304, it is detected whether the value of the first flag bit is equal to a second predetermined threshold.
The terminal may detect whether the value of the first flag bit is equal to the second preset threshold, execute step 305 if the value of the first flag bit is equal to the second preset threshold, otherwise return to step 301 above and continue to receive the first trigger signal, that is, execute the step of receiving the first trigger signal when the value of the first flag bit is not equal to the second preset threshold.
The second preset threshold may be a value preset in the terminal and the same as the first confirmation value, that is, the terminal may determine whether the terminal acquires the first touch data by detecting whether the value of the first flag is equal to the second preset threshold.
In a possible implementation manner, this step may also be replaced by detecting whether the terminal writes the first confirmation value in the first flag bit, or reflecting whether the terminal acquires the first touch data, which is not limited in this embodiment of the application.
And 305, recording a second zone bit according to the unique identifier in the first touch data when the value of the first zone bit is equal to a second preset threshold value.
The second flag bit is used for indicating whether the first touch data corresponds to the first flag bit with the value of the first confirmation value. Optionally, the implementation manner of the second flag bit may refer to the description in step 205, and is not described herein again.
Optionally, when the terminal detects that the value in the first flag bit is equal to the second preset threshold, it indicates that the terminal has acquired the first touch data, and writes the first confirmation value into the first flag bit for the first touch data, at this time, the terminal may record that the unique identifier of the first touch data has the second flag bit, and indicate the unique identifier through the second flag bit.
In a possible implementation manner, when the value of the first flag bit is equal to the second preset threshold, a second confirmation value is written in the second flag bit, and the second flag bit is recorded according to the unique identifier in the first touch data and the second confirmation value. The second confirmation value may indicate that the first touch data corresponds to a first flag bit taking the first confirmation value.
For example, the values of the second flag bits are represented by 0 and 1, where 0 may be used as a default value of the second flag bit and 1 may be used as a written second confirmation value, and when the value of the first flag bit is equal to a second preset threshold, the terminal may rewrite the value of the second flag bit from 0 to 1, thereby indicating that the first touch data corresponds to the first flag bit taking the value of the first confirmation value.
Optionally, the terminal may further record and record a second flag bit by using the unique identifier in the first touch data and the second confirmation value, which indicates that the unique identifier in the terminal is the unique identifier in the first touch data, and the second flag bit is recorded in the first trigger signal whose value is the second confirmation value. In a possible implementation manner, the terminal may record the second flag bit according to the unique identifier in the first touch data and the second confirmation value in a table form.
Please refer to table 1, which shows a second flag bit record table according to an exemplary embodiment of the present application.
| Unique identification | Second confirmation value |
| Identification one | 1 |
| Identification two | 1 |
| …… | …… |
TABLE 1
As shown in table 1, after receiving the first trigger signal, the terminal may record the value written in the second flag bit according to the unique identifier in the first touch data. In a possible implementation manner, the unique identifier in the first touch data adopted in the above may be a trigger number in the first touch data. Corresponding to the above-mentioned alternative mode, the trigger number may also be a finger number.
Optionally, when the value of the first flag is equal to the second preset threshold, the terminal may detect a third trigger signal in the touch display screen according to the unique identifier in the first touch data. The third trigger signal is a signal corresponding to any one of a moving operation, a long-time pressing operation or a lifting operation detected in the touch display screen.
That is, when the value of the first flag is equal to the second preset threshold, the third trigger signal subsequently detected by the terminal in the touch display screen is marked according to the unique identifier in the first touch data. For example, after the user touches the touch display screen of the terminal, the user may move in the touch display screen of the terminal to complete the moving operation, or the user keeps touching the touch display screen of the terminal for a preset duration, and the terminal determines that the operation is a long-time pressing operation, or the user releases the action of touching the touch display screen of the terminal this time to complete the lifting operation. And when the terminal records the signals corresponding to the operations, the signals are marked according to the unique identification in the first touch data.
For example, after the user touches and moves in the touch display screen of the terminal, the terminal completes the moving operation, after the above steps 301 to 305 are completed according to the touch operation just started, the terminal may generate current data for the subsequent movement of the user in the touch display screen, the current data may include data such as touch coordinates, pressure magnitude, moving path, and the like, which change during the movement, and the terminal may associate the obtained unique identifier with the data, so as to know which of the previous first trigger signals corresponds to the current data.
Alternatively, the second trigger signal may be regarded as one of the third trigger signals, that is, the second trigger signal may correspond to a signal for a lift-off operation. That is, when an object generating the first departure signal in the touch display screen moves away from the touch display screen of the terminal, the touch between the object and the touch display screen is released, and the terminal can receive the trigger signal through the touch display screen. Similarly, the terminal may also identify the received second trigger signal according to the unique identifier in the first touch data.
After receiving the second trigger signal, the terminal may obtain the unique identifier in the first touch data indicating the second trigger signal, obtain the second flag bit of the record according to the unique identifier in the first touch data, and detect whether the value of the second flag bit is equal to the first preset threshold. If the recorded value of the second flag bit is equal to the first preset threshold, step 308 is executed, and if the recorded value of the second flag bit is not equal to the first preset threshold, the terminal may end the data obtaining method.
Optionally, the first preset threshold may also be equal to the second confirmation value, so that the terminal may determine that the first touch data acquired by the terminal corresponds to the first flag bit taking the first confirmation value by detecting the value of the second flag bit.
And 308, when the value of the second flag bit is equal to the first preset threshold, acquiring second touch data according to a second trigger signal, wherein the second touch data is generated by triggering the second trigger signal in the touch display screen.
Namely, after detecting that the value of the second zone bit is equal to the first preset threshold value, the terminal executes the step of acquiring the second touch data according to the second trigger signal. Optionally, the obtaining of the second touch data is similar to the obtaining of the first touch data, and details are not repeated here.
The data content included in the second touch data may be the same as or different from the data content included in the first touch data. The terminal may also mark the acquired second touch data by a unique identification of the first touch data.
In a possible implementation manner, the terminal may further detect whether a third confirmation value is written in a third flag bit by the terminal, where the third flag bit is used to indicate whether the terminal acquires the second touch data, and the third confirmation value indicates that the terminal acquires the second touch data.
Optionally, the implementation manner of the third flag bit here may refer to the setting manner of the second flag bit in step 305, and is not described here again. The terminal determines whether the terminal acquires the second touch data or not by detecting a third confirmation value in the third zone bit, and when the terminal detects that the third confirmation value is written in the third zone bit, the terminal indicates that the terminal acquires the second touch data, so that the data acquisition method is executed.
Optionally, when the third confirmation value is not written in the third flag bit, the step of acquiring the second touch data according to the second trigger signal is performed.
That is, when the terminal detects that the third confirmation value is not written in the third flag bit, it indicates that the terminal does not acquire the second touch data, the step 306 of acquiring the second touch data according to the second trigger signal may be continuously performed until the terminal acquires the second touch data, and the third confirmation value is written in the third flag bit, so that the data acquisition method is completed.
