Detailed Description
To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
In the related art, when the touch display screen collects touch data, the touch display screen is interfered by an external environment, so that the calculated touch coordinate is not accurate enough. According to the technical scheme, when the touch display screen is in the dormant state, if the touch event is detected, the sampling frequency of collected touch data is improved, so that more touch data can be collected within the duration of the touch event, then the collected touch data are subjected to statistical processing to obtain a processing result, data verification is performed through more touch data, the probability of inaccurate calculation of touch coordinates caused by external environment interference can be reduced, and the accuracy of the touch coordinates is improved. In addition, the touch data can be subjected to statistical processing, abnormal data can be removed in the statistical processing process, and the accuracy of the touch coordinate can be improved.
According to the technical scheme provided by the embodiment of the application, the execution main body of each step can be a terminal or a touch display screen in the terminal. In the embodiments of the present application, only the main execution body of each step is taken as an example of a touch display screen.
Referring to fig. 1, a flowchart of a touch data processing method according to an embodiment of the present application is shown. The method can be applied to a touch display screen, and comprises the following steps:
If the touch display screen does not detect the touch event within a period of time, the touch display screen enters a sleep state. The first touch event refers to an event that a user performs a touch operation on the touch display screen. The value of N can be actually determined according to the magnitude of the first sampling frequency. The larger the first sampling frequency is, the larger the value of n is; the smaller the first sampling frequency is, the smaller the value of n is.
The first sampling frequency is greater than the second sampling frequency, and the second sampling frequency is the sampling frequency adopted when the touch display screen is in the awakening state. The sampling frequency refers to the frequency of touch data collected by the touch display screen. The first sampling frequency may be preset and limited, may also be actually set according to a current operating condition of the terminal, and may also be actually determined according to a signal type corresponding to a touch event, which is not limited in the embodiment of the present application.
In one possible implementation, the first sampling frequency includes a third sampling frequency and a fourth sampling frequency. The third sampling frequency is greater than the fourth sampling frequency. The third sampling frequency and the fourth sampling frequency may be set according to actual requirements, which is not limited in the embodiment of the present application. The n sets of touch data include third touch data and fourth touch data. The first touch data refers to touch data collected according to a third sampling frequency. The second touch data refers to touch data collected at a fourth sampling frequency.
The second preset time period may be set according to practical experience, which is not limited in the embodiment of the present application. The touch event with the longer duration may be any one of a long-press operation signal, a slide operation signal, and a drag operation signal. For a touch event with a long duration, the coordinates of the position where the user finger just starts to contact the touch display screen are touch coordinates needing important attention, taking a long-press operation signal as an example, the user finger keeps a certain time after contacting the touch display screen, and the coordinates of the position where the user finger just starts to contact the touch display screen are also touch coordinates corresponding to the long-press operation signal.
In the embodiment of the present application, for the touch event with longer duration, the terminal increases the sampling frequency when the terminal just starts to detect the touch event, so as to accurately locate the coordinates of the position where the finger of the user just contacts the touch display screen, and the subsequent touch display screen reduces the sampling frequency, so as to save the power consumption of the terminal.
As mentioned in the above embodiments, the touch event having a longer duration may also be a slide operation signal or a drag operation signal. The touch coordinates corresponding to the slide operation signal or the drag operation signal generally include a plurality of coordinates, and the coordinates of which the focus is on include the coordinates of the position where the user's finger has first contacted the touch display screen, as well as the coordinates of the position where the user's finger has last contacted the touch display screen. In this case, the touch display screen further performs the steps of: and detecting whether the fluctuation amplitude of the first touch data meets a preset condition, if so, executing the step of acquiring second touch data according to a fourth sampling frequency, and if not, not executing the step of acquiring the second touch data according to the fourth sampling frequency.
The preset condition may be that the fluctuation amplitude of the first touch data is in a small range. The pressing operation signal is generated after the finger of the user is kept in contact with the touch display screen for a certain time, and the sliding operation signal or the dragging operation signal is generated when the finger of the user is in contact with the touch display screen and slides on the touch display screen. Therefore, when the fluctuation amplitude of the touch data detected by the touch display screen is small, the long press operation signal is considered to be received; when the fluctuation amplitude of the touch data detected by the touch display screen is large, the sliding operation signal or the dragging operation signal is considered to be received. In this implementation, when the touch display screen detects that the sliding operation signal or the dragging operation signal is received, the touch data is still collected according to the increased sampling frequency, so that other coordinates except the coordinates of the position where the user finger has just contacted the touch display screen can be accurately located.
And 102, performing statistical processing on the n groups of touch data to obtain processing results corresponding to the n groups of touch data.
In the embodiment of the application, the touch display screen performs statistical processing on a plurality of groups of touch data acquired after the sampling frequency is increased to obtain corresponding processing results, and then calculates the touch coordinates according to the processing results.
Optionally, step 102 may include the following two substeps:
102a, screening n groups of touch data to obtain screened touch data;
the screening process is to remove abnormal data in the n sets of touch data. Anomalous data refers to data that is significantly unreasonable, such as data that differs significantly from other data.
Step 102a may be implemented as: detecting whether the touch data acquired by a first group in the n groups of touch data is abnormal data or not; and if the first group of the acquired touch data is abnormal data, removing the first acquired touch data to obtain the touch data after screening processing.
Because the touch display screen is in the dormant state, if a first touch event is detected, the touch display screen needs to be switched to the awakening state from the dormant state at the moment, and the touch display screen can be charged and discharged in the process, so that the collected touch data can be interfered by charging and discharging, and the touch data is not accurate enough. In this case, the touch display screen may detect whether a difference between the first group of acquired touch data and the subsequently acquired touch data is large, and if the difference is large, it indicates that the first group of acquired touch data is abnormal data and needs to be removed, and if the difference is small, it indicates that the first group of acquired touch data is not abnormal data and may be retained.
And step 102b, processing the touch data after the screening processing through a preset algorithm to obtain processing results corresponding to the n groups of touch data.
The preset algorithm may be any one of the following: the method includes a multiple data point approach point algorithm, a center point algorithm, a straight line fitting algorithm and the like, which are not limited in the embodiment of the application.
And 103, calculating touch coordinates corresponding to the first touch event according to processing results corresponding to the n groups of touch data.
And the touch display screen calculates touch coordinates corresponding to the first touch event according to the processing results corresponding to the n groups of touch data.
Referring to fig. 2, a flowchart of a touch data processing method according to an embodiment of the present application is shown. When a user clicks a touch screen for the first time, the touch screen improves the sampling rate of the touch screen, samples data for multiple times, verifies the data, detects whether the touch data are different greatly, discards the data with large errors if the touch data are different greatly, and performs algorithm optimization processing on the rest data; if not, directly carrying out algorithm optimization processing.
To sum up, the technical scheme provided by the embodiment of the application improves the sampling frequency of collecting touch data if a touch event is detected when the touch display screen is in a dormant state, so that more touch data can be collected within the duration of the touch event, then the collected touch data is subjected to statistical processing to obtain a processing result, and data verification is performed through more touch data, so that the occurrence probability of inaccurate touch coordinate calculation caused by external environment interference can be reduced, and the accuracy of the touch coordinate is improved.
In addition, the touch data can be subjected to statistical processing, abnormal data can be removed in the statistical processing process, and the accuracy of the touch coordinate can be improved.
In the embodiment of fig. 1, it is mentioned that the first sampling frequency may also be actually set according to the current operation condition of the terminal. This case will be explained below.
In an optional embodiment provided based on the embodiment shown in fig. 1, before step 102, the touch data acquisition method may further include the following steps: and receiving a first sampling frequency transmitted by an operating system.
The first sampling frequency is determined by the operating system according to the touch accuracy requirement. The touch precision requirement is used for indicating the precision requirement of the terminal on the touch coordinate. Optionally, the operating system divides the touch accuracy requirement into a plurality of levels, each level corresponding to a respective first sampling frequency. Illustratively, the touch accuracy requirements may include three levels, low, medium, and high. The first sampling frequency corresponding to the low touch precision requirement is the lowest, the first sampling frequency corresponding to the high touch precision requirement is the highest, and the first sampling frequency corresponding to the medium touch precision requirement is between the first sampling frequency and the medium touch precision requirement.
When the touch display screen detects a touch event, sending a frequency acquisition request to an operating system, determining a touch precision requirement level by the operating system according to running information of the terminal, then searching the corresponding relation between the first sampling frequency and the touch precision requirement level to obtain the first sampling frequency, and returning the first sampling frequency to the touch display screen.
The touch precision requirement is actually determined by an operating system according to the running information of the terminal, and the running information of the terminal comprises one or more of the following combinations: the method comprises the steps of operating the application programs in the foreground, operating scenes where the application programs in the foreground are operated, the number of operable objects included in a current display interface and the area of the operable objects.
The operable object refers to an object having a capability of responding to an operation signal, that is, when the terminal receives a trigger operation signal corresponding to the operable object, the terminal may respond to the trigger operation signal, for example, display a certain interface (e.g., a main interface of an application program, a next-level interface), and perform a certain function (e.g., turn on a flashlight, control a motion of a virtual object, etc.). The operable objects in the embodiment of the application can be provided by an operating system, such as application icons and function icons. The actionable objects in embodiments of the present application may also be provided by an application, such as a virtual control displayed in a user interface of the application, and so forth.
The more the number of operable objects included in the current display interface is, the higher the touch precision requirement is; the fewer the number of actionable objects that the current display interface includes, the lower the touch accuracy requirement. The smaller the area of the operable object is, the higher the touch precision requirement is; the larger the area of the operable object, the lower the touch accuracy requirement. The setting mode can reduce the false touch probability.
It should be noted that, when the operation information of the terminal includes at least two items, the operating system may quantize each item of operation information into a specific numerical value, set a corresponding coefficient, and then accumulate the products of the specific numerical value and the coefficient to obtain a result numerical value, where a level corresponding to the result numerical value is also a level corresponding to the touch precision requirement.
According to the technical scheme provided by the embodiment of the application, the touch precision requirement can be determined according to the operation information of the terminal, the first sampling frequency is further determined according to the touch precision requirement, and the first sampling frequency can be flexibly determined by combining the operation information of the terminal.
Referring to fig. 3, a flowchart of a touch data processing method according to an embodiment of the present application is shown. The method is applied to the touch display screen, and can comprise the following steps:
The first sampling frequency is greater than the second sampling frequency, and the second sampling frequency is the sampling frequency adopted when the touch display screen is in the awakening state.
And 102, performing statistical processing on the n groups of touch data to obtain processing results corresponding to the n groups of touch data.
And 103, calculating touch coordinates corresponding to the first touch event according to processing results corresponding to the n groups of touch data.
The time interval between the occurrence time of the second touch event and the occurrence time of the first touch event is less than a first preset time, and the occurrence time of the second touch event is later than the occurrence time of the first touch event.
In a possible implementation manner, the touch display screen sets a region, which takes the touch coordinate corresponding to the first touch event as a center and has an area of a preset area, as a touch range corresponding to the second touch event. The preset area can be set according to actual requirements, and the embodiment of the application does not limit the preset area.
In another possible implementation manner, the terminal displays a designated user interface after responding to the first touch event, the designated user interface has an operable object, and the touch display screen sets a preset range including the operable object as a touch range corresponding to the second touch event.
In another possible implementation manner, a plurality of operable objects exist in the designated user interface, the trigger probabilities corresponding to the operable objects are different, the touch display screen determines a target operable object whose trigger probability meets a preset condition, and then a preset range including the target operable object is set as a touch range corresponding to the second touch event. The preset condition may be that the trigger probability is first n bits, or the trigger probability is greater than the preset probability, and so on.
In another possible implementation manner, the touch display screen determines the touch range corresponding to the second touch event through a deep learning model. And the touch display screen transmits the touch coordinate corresponding to the first touch event to an operating system, and the operating system inputs the touch coordinate corresponding to the first touch event into a deep learning model to obtain a touch range corresponding to a second touch event. The deep learning model is obtained by training a deep learning network through a plurality of sample touch coordinates, and the sample touch coordinates correspond to the marked touch range.
The touch data corresponding to the second touch event refers to touch data acquired when the second touch event is detected by touch. In the embodiment of the application, if the touch data corresponding to the second touch event has touch data which does not belong to the touch range, the touch data which does not belong to the touch range is removed, so that interference can be eliminated, and the accuracy of the touch coordinate is improved.
And step 306, calculating touch coordinates corresponding to the second touch event according to the touch data corresponding to the screened second touch event.
According to the technical scheme provided by the embodiment of the application, after the touch coordinate corresponding to the first touch event is calculated, if the second touch event is detected in a short time, the touch range corresponding to the second touch event is firstly determined according to the touch coordinate corresponding to the first touch event, and the touch data corresponding to the second touch event is screened by utilizing the touch range, so that interference can be eliminated, and the accuracy of the touch coordinate is improved.
Referring to fig. 4, a flowchart of a touch data processing method according to an embodiment of the present application is shown. The method may comprise the steps of:
The query information is used for querying whether an operable object exists in the current display interface. The operable object refers to an object having a capability of responding to an operation signal. Correspondingly, the operating system receives the query information, detects whether an operable object exists in the current display interface according to the query information, obtains reply information, and returns the reply information to the touch display screen.
The operating system can detect whether an operable object exists in the current display interface through the following two implementation modes: in a possible implementation manner, the operating system detects whether the current display interface is a designated interface, and if the current display interface is the designated interface, the current display interface does not include an operable object; and if the current display interface is not the designated interface, the current display interface comprises the operable object. The designated interface can be a video playing interface or an electronic book reading interface. In other possible implementation manners, the operating system may further obtain attribute information of each UI element included in the current display interface from a rendering process of the current display interface, and detect whether an operable object exists in the current display interface according to the attribute information of each UI element.
In step 403, if the reply information is used to indicate that an operable object exists in the current display interface, acquiring n sets of touch data according to a first sampling frequency.
If the reply information is used for indicating that no operable object exists in the current display interface, the step of collecting n groups of touch data according to the first sampling frequency is not executed, that is, the technical scheme provided by the embodiment of the application is not executed.
When the current display interface does not include the operable object, the action range of the touch operation performed by the user is generally the whole touch display screen, and at this time, the requirement on the accuracy of the touch coordinate is low, the touch display screen determines whether to increase the sampling frequency according to the attribute so as to increase the calculation accuracy of the touch coordinate, if the current display interface includes the operable object, the sampling frequency is increased, and if the current display interface does not include the operable object, the sampling frequency is not increased.
By the method, two aspects of power consumption of the terminal, calculation accuracy of the touch coordinate and the like can be considered, the sampling frequency is not increased when the accuracy requirement on the touch coordinate is low so as to save power consumption, and the sampling frequency is increased when the calculation accuracy requirement on the touch coordinate is high so as to improve the calculation accuracy of the touch coordinate.
And step 404, performing statistical processing on the n groups of touch data to obtain processing results corresponding to the n groups of touch data.
In summary, according to the technical scheme provided by the embodiment of the application, the sampling frequency of the collected touch data is increased when the operable object exists in the current display interface, so that the calculation accuracy of the touch coordinate is improved, and the probability of false triggering is reduced; and touch data are collected according to the original sampling frequency when no operable object exists in the current display interface, so that the power consumption of the terminal is saved.
