Fig. 4 is a flowchart illustrating an identification method according to an embodiment of the present application. As shown in fig. 4, the method includes the following steps S310-S330.
Step S310: and acquiring the touch variation corresponding to the test point.
The touch variation is data indicating a touch behavior on the touch screen. Touch sensors are arranged at all positions of the touch screen, and the touch sensors can acquire the screen touch quantity in real time. And taking the screen touch quantity acquired in the non-touch state as a reference touch quantity, and subtracting the reference touch quantity from the screen touch quantity to obtain the touch variation at the moment. The test points in this step are referred to as touch sensors. And obtaining the screen touch quantity collected by the test point on the preset position of the screen, and subtracting the reference touch quantity to obtain the touch variation corresponding to the test point.
Step S320: calculating the number of target test points which accord with a first preset condition in the test points; the first preset condition includes: and the touch variation corresponding to the test points is larger than the average value of the touch variation, and the test points are communicated.
When two screens are overlapped together, a large connected area with large touch variation exists. Therefore, in this step, the number of the mutually connected test points in which the touch variation is larger than the average value of the touch variation is calculated, and the number of the test points is taken as the number of the target test points. Wherein, connected means that a certain target test point is at least adjacent to one other target test point.
Step S330: and when the number of the target test points is larger than the preset value of the number of the test points, determining the current frame as a stacked screen and laid down effective frame.
The touch variation is acquired at preset time intervals, and each acquisition is called a frame. The effective frame of the folded screen and the put-down frame means that the screens of the two complete machines are in an overlapped state in the current frame, or the two folded screens of the folded screen equipment are in an overlapped state. In this step, when the number of the target test points is greater than the preset value of the number of the test points, the current frame is determined to be a stacked screen and effective frame put down.
According to the technical scheme provided by the embodiment of the application, the number of the target test points meeting the first preset condition in the test points is calculated by obtaining the touch variation corresponding to the test points, and when the number of the target test points is greater than the preset value of the number of the test points, the current frame is determined to be a stacked screen and an effective frame is put down, so that the identification of the stacked screen mode is realized, whether the reference touch quantity is updated or not can be determined according to whether the stacked screen mode appears or not in the subsequent touch identification, and the accuracy of the touch identification is improved.
In an embodiment, the method provided in the embodiment of the present application further includes: and according to a preset time interval, repeatedly acquiring the touch variation and judging the effective frame of the overlapped screen put-down, and when the continuous frame number of the effective frame of the overlapped screen put-down is greater than the preset frame number, determining that the current mode is the overlapped screen put-down mode.
When the current frame is determined to be a screen-overlap-down valid frame, it is stated that the screen may overlap another screen at this frame. However, noise and other factors may also cause the occurrence of effective frames during screen overlapping and dropping, which may cause misjudgment of the screen overlapping and dropping mode. Generally, when the effective frame is put down by overlapping the screen for a certain number of frames, the influence of other external factors can be eliminated. Therefore, it can be further determined that the current screen-folding drop mode is indeed in by continuing screen-folding drop active frames.
In this step, the touch variation is obtained at preset time intervals, and each time is called a frame. In each frame, according to the method provided by the embodiment corresponding to fig. 4, the touch amount is obtained and the effective frame is determined by overlapping the screen and dropping the screen. And if the continuous frame number of the effective frame put down by the overlapped screen is greater than the preset frame number value, determining that the current mode is the overlapped screen put down mode.
In an embodiment, the obtaining of the touch variation corresponding to the test point may be obtaining of the touch variation corresponding to the full-screen test point. And acquiring the screen touch quantity corresponding to the test point of the full screen, and subtracting the reference touch quantity at the corresponding position to obtain the touch variation corresponding to the test point of the full screen.
In one embodiment, as shown in FIG. 5, before step S320, the method further includes the following steps S410-S430.
Step S410: and traversing the full-screen test points, and counting the number of the first test points with the touch variation larger than the average value of the touch variation.
The touch variation average value is an average value of touch variations corresponding to the full-screen test point. The number of the first test points is the number of the test points with the touch variation larger than the average value of the touch variation.
Step S420: and judging whether a second test point with the touch variation in the preset interval exists or not.
The preset interval may be a certain interval in which the left endpoint of the interval is greater than the average value of the touch variation. In one embodiment, the preset interval is (diffaverage + (diffax-diffaverage)/2 ∞), where diffaverage represents the average value of the touch variation and diffax represents the maximum value of the touch variation. The second test point is a test point in a preset interval. And traversing the full screen test points, and if the test points are in the preset interval, determining that the second test point exists.
Step S430: judging whether a second preset condition is met, and calculating the number of target test points in the full screen test points when the second preset condition is met; the second preset condition includes: the second test points exist, the average value of the touch variation is larger than a first preset value, and the number of the first test points is larger than a second preset value.
Wherein, the second preset value can be calculated by adopting formula (1):
wherein ValidDifCntTh represents a second preset value, RowMax represents the number of rows of the matrix of the test points, ColMax represents the number of columns of the matrix of the test points, and x, y and z are configuration parameters; x is in the interval [1, RowMax]Y is in the interval (1, ColMax), z is in the interval
In an embodiment, step S410 specifically includes: judging whether the maximum value of the full-screen touch variation is within a preset range; and when the touch variation is within the preset range, counting the number of the first test points with the touch variation larger than the average value of the touch variation.
Wherein the preset range may be expressed as (Thlo, thi), which respectively represent a low preset value and a high preset value of the maximum value of the touch variation amount. When the maximum value of the touch variation is in the preset range, the maximum value is in a state that the two screens are overlapped, so that the next judgment is carried out.
In an embodiment, before determining whether the maximum value of the full screen touch variation is within the preset range, it may be determined whether the switch of the screen folding processing mechanism is turned on. And when the switch of the screen folding processing mechanism is turned on, judging the maximum value of the full screen touch quantity.
In one embodiment, as shown in fig. 6, step S320 specifically includes the following steps S510-S540.
Step S510: and selecting a second test point as a first starting test point.
Wherein, the first starting test point refers to the starting test point of all the searching steps. In an embodiment, the first second test point searched in step S420 may be selected as the first start test point.
Step S520: and searching for the test points which are larger than the average value of the touch variation in the test points at the upper, lower, left and right positions of the first starting test point.
The test points are arranged on the screen at certain intervals in a matrix form. In this step, four test points at the upper, lower, left and right positions of the first start test point are searched, and a test point larger than the average value of the touch test points among the four test points is found.
Step S530: and repeating the searching process by taking the test point larger than the average value of the touch variation as a second initial test point until no test point larger than the average value of the touch variation exists.
And the second starting test point refers to the starting test point of the searching step. And taking the test point which is searched in the S520 and is larger than the average value of the touch variation as the initial test point of the search, searching the test points which are larger than the average value of the touch variation on the upper, lower, left and right positions of the second initial test point by adopting the same searching method, and repeating the searching process until no test point which is larger than the average value of the touch variation exists.
Step S540: counting the number of the searched test points which are larger than the average value of the touch variation; and counting the number of the test points to obtain the number of the target test points.
And after the search is finished, counting the number of all searched test points. Because each searching process extends from the initial test point to the test points at the upper, lower, left and right positions, all the test points form a communication area, and the test points are communicated. Moreover, each time the test points are searched for, the touch variation of all the searched test points is larger than the average value of the touch variation. Therefore, the test points obtained by searching are all target test points meeting the first preset condition. And counting the number of the test points obtained by searching, and taking the number as the number of the target test points.
In an embodiment, the preset value of the number of the test points is obtained by calculating according to the following steps: calculating the touch variation level according to the average value of the touch variation; if the touch variation level is equal to 0, the preset value of the number of the test points is the second preset value; otherwise, the preset value of the number of the test points is a result obtained by dividing the second preset value by the touch variable quantity grade.
The touch variation level is an index for measuring the level of the touch variation. In one embodiment, the touch variation level can be calculated by equation (2):
Diflevel＝DifAverage/10 (2)
wherein, diffevel represents the touch variation level, and diffaverage represents the average value of the touch variation. In addition, the second preset value can be calculated by using the formula (1).
In an embodiment, after determining that the screen-folding-down mode is currently in, the method further comprises: and setting the flag position triggering the reference touch quantity updating mechanism as no.
When two screens are overlapped, the screen overlapping area can increase the screen touch amount due to the action of the touch screen. This triggers an update mechanism of the reference touch amount, so that the reference touch amount is updated to the screen touch amount after screen folding. After the screen stack is lifted, the updating of the reference touch amount may cause that the touch behavior cannot be recognized. Therefore, the reference touch amount at the time of screen stacking should be maintained at a value before screen stacking. Therefore, after the current screen folding and dropping mode is determined, the flag position for triggering the reference touch quantity updating mechanism is set to be negative, so that the condition that the reference touch quantity updating mechanism is not triggered is ensured, and the accuracy of subsequent touch identification can be improved.
In one embodiment, as shown in FIG. 7, after determining that the screen-folding-down mode is currently in use, the method further includes the following steps S610-S630.
Step S610: and acquiring the touch variation corresponding to the test point.
When one screen is overlapped on another screen, the screen may be lifted up after a while. Therefore, after the current screen folding and dropping mode is determined, the judgment of the screen folding and lifting mode can be carried out immediately. In this step, the touch variation corresponding to the test point at the preset position of the screen is obtained. In an embodiment, the touch variation corresponding to the full screen test point may be obtained.
Step S620: and traversing the test points, and acquiring the number of third test points with the touch variation smaller than a third preset value and the number of first test points with the touch variation larger than the average value of the touch variation.
In an embodiment, the third preset value may be obtained according to a preset range of a maximum value of the touch variation. As described above, the preset range of the touch variation amount may be represented as (Thlo, Thhi), and the third preset value may be represented as-Thlo/3.
Step S630: judging whether a third preset condition is met, and determining that the current frame is a screen-folding uplifting effective frame when the third preset condition is met; the third preset condition includes: the average value of the touch variation is smaller than a first preset value, the number of the first test points is smaller than a preset value of the number of the test points, and the number of the third test points is smaller than a preset value of the number of the test points.
The preset value of the number of the test points can be calculated according to the method provided by the embodiment. When one screen is lifted from two screens, the screen touch amount is obviously reduced, and the touch variation is also obviously reduced because the reference touch amount is not changed. In addition, due to the function of screen folding, the touch variation of the screen folding area can be in an unstable state, a small part of the touch variation can be changed into a negative value, and the number of the test points smaller than a certain negative value is not too many. Therefore, in this step, whether the current frame is a screen-folding lifting effective frame is judged by judging whether the average value of the touch variation is smaller than a first preset value, whether the number of the first test points is smaller than a preset value of the number of the test points, and whether the number of the third test points is smaller than the preset value of the number of the test points.
In an embodiment, after determining that the current frame is a screen-folding lifting valid frame, the method provided in the embodiment of the present application further includes:
and according to a preset time interval, repeatedly performing the operation of acquiring the touch variable quantity and judging whether the effective frame is lifted by the overlapped screen, and when the continuous frame number of the effective frame lifted by the overlapped screen is greater than the preset frame number, determining that the current mode is the overlapped screen lifting mode.
The judgment of the overlapped screen lifting mode is the same as that of the overlapped screen lowering mode, and in order to avoid misjudgment caused by other factors, when the continuous frame number of the overlapped screen lifting effective frame is greater than the preset frame number value, the overlapped screen lifting mode is determined at present.
In an embodiment, after the determining that the current screen folding and lifting mode is the screen folding and lifting mode, a method provided by an embodiment of the present application further includes: the update of the reference touch amount is started.
After the current mode is determined to be the screen folding and lifting mode, updating of the reference touch quantity is started, and the zone bit of the screen folding and lowering mode and the zone bit of the screen folding and lifting mode are cleared.
Fig. 8 is a process diagram of an identification method according to another embodiment of the present application. As shown in fig. 8, the process includes the following steps S701 to S714.
S701: acquiring touch variation corresponding to a full-screen test point;
s702: calculating the number of target test points which accord with a first preset condition in the full screen test points;
