Detailed Description
The embodiments of the present application will be described below with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 is a method for determining a touch skip point according to an embodiment of the present disclosure. As shown in fig. 1, the method may include at least the following steps.
Step S101, acquiring touch point P reported by flexible sensor for the Nth timeNPosition information of (1) th touch point P and touch point P reported at the N-1 st timeN-1N is an integer, and N is not less than 3.
For example, the flexible sensor may detect a touch operation and periodically report position information of a touch point in the touch operation. The position information of the touch point can be understood as coordinate information of the touch point. The coordinate axis on which the coordinate information is based may be established based on a touch screen configured with the flexible sensor, and is not limited herein.
Exemplarily, when the touch point P reported by the flexible sensor for the first time is obtained1After the position information, the touch point P can be determined1The location information of (2) is stored. In the embodiment of the present application, the position information of the touch point is saved in the variable lastpoint as an example. Here, the touch point P may be first touched1Is saved to the variable lastpoint.
When a touch point P reported by the flexible sensor for the second time is obtained2After the position information, the touch point P can be determined1Position information and touch point P2Determines a touch point P1And touch point P2The distance between them. And the distance may be saved. In the embodiment of the application, the touch point P is used1And touch point P2The distance between them is stored in the variable lastresistance for the purpose of illustration. And can touch the point P2Saving to the variable lastpoint, that is, updating the value in the variable lastpoint to the touch point P2The location information of (1).
When a touch point P reported by the flexible sensor for the Nth time is obtainedNAfter the position information, the touch point P can be determined according to the following stepsNWhether the touch control jumping point is detected. Wherein N is an integer greater than or equal to 3.
Step S102, according to the touch point PNAnd the touch point PN-1Determining the touch point PNAnd the touch point PN-1A first distance therebetween.
Step S103, judging whether the first distance is larger than a first distance threshold value.
Illustratively, when the touch point P is determinedNAnd touch point PN-1After the first distance, it may be determined whether the first distance is greater than a first distance threshold.
Wherein the first distance threshold may be the distance held in the variable lastdistance. Alternatively, the first distance threshold may be the product of the distance in the variable lastdistance and its corresponding parameter. That is, the first distance threshold may be represented by equation (1): dthreshold1＝DlastdistanceAnd x a is determined. Wherein D isthreshold1Is a first distance threshold, DlastdistanceIs the distance in variable lastvariance, and a is the parameter corresponding to the distance in variable lastvariance. Wherein, the distance unit is a report point of the flexible display screen.
One correspondence of distance to parameter in the variable lastvariance can be seen in table 1.
Dlastdistance a

TABLE 1
Of course, the first distance threshold may be determined in other manners, which are not limited herein.
Further, the distance in the variable lastdistance may be according to the touch point PN-1Touch point P reported with flexible sensor N-2 timesN-2The distance between them is determined.
In one case, the distance in the variable lastdistance may be the touch point PN-1And touch point PN-2The distance between them. For example, when N is 3, the distance in the variable lastdistance is the touch point P2And touch point P1The distance between them.
In another case, when N is>3, the distance in the variable lastdistance may be the touch point PN-1And touch point PN-2Distance between and touch point PN-2And touch point PN-3The distance between them is determined by weighting.
The distance in the variable lastdistance may also be determined in a combination of the two above, which is not limited herein.
The above implementation is exemplified below.
When N is 3, touch point P is held in variable lastpoint2Can be based on the touch point P2Position information and touch point P3Determines a touch point P3And touch point P2The distance between them. Further, the distance in the variable lastdistance is the touch point P2And touch point P1The distance between them. The first distance threshold is determined based on the distance in the variable lastdistance and the correspondence in table 1 above. And determines a touch point P3And touch point P2If the distance between the first and second points is greater than the first distance threshold, step S104 is executed. If the touch point is smaller than the preset value, determining a touch point P3Not a touch skip point. Can touch the point P3Saves to the variable lastpoint and updates the distance in the variable lastdistance. Further acquiring the touch point P reported next time by the flexible display screen4The location information of (2) is skipped to execute steps S101 to S103.
Specifically, the distance in the updated variable lastdistance is the touch point P3And touch point P2A distance D between32And touch point P2And touch point P1A distance D between21And (4) obtaining the result by weighting.
For example, equation (2) may be utilized: dnew_lastdistance＝K1×Dlastdistance+K2×DnowdistanceTo get the distance in the updated variable lastvariance. Wherein D isnew_lastdistanceRepresents the distance in the updated variable lastvariance; dlastdistanceRepresents the distance in the variable lastdistance before update, where D may be represented21；DnowdistanceRepresents the distance between the currently acquired touch point and the last acquired touch point, and may represent D herein32(ii) a Wherein, K1Represents DlastdistanceWeight value of, K2Represents DnowdistanceThe weight value of (2). Wherein, K1And K2The sum of which is 1, K1Can be greater than K2The value of (a). For example, K1Can be 0.75, K2The value of (a) may be 0.25, which is not limited herein.
Then at the confirmed touch point P3After the touch jumping point is not reached, the distance in the variable lastdistance is updated to be K1×D21+K2×D32。
When N is 4, acquiring a touch point P4And acquires the touch point P from the variable lastpoint3The location information of (1). Determining a touch point P according to the position information of the two touch points4And touch point P3A distance D between43. And determines a first distance threshold according to the distance in the variable lastdistance and the corresponding relationship in table 1. Here, the distance in the variable lastvariance is obtained based on the formula (2) described above. Can judge the distance D43If the distance is greater than the first distance threshold, step S104 is executed, and if the distance is less than the first distance threshold, the touch point P may be determined4Not a touch skip point. Can touch the point P4To the variable lastpoint, and the distance in variable lastdistance may be updated according to equation (2). Further acquiring the touch point P reported next time by the flexible display screen5The location information of (2) is skipped to execute steps S101 to S103.
For the case that N ≧ 5, the implementation of N ≧ 4 can be referred to, which is not described herein.
By the method, the distance threshold is associated with the position information of the touch point, so that the touch jumping point judgment accuracy can be improved.
Step S104, if yes, determining the touch point PNIs a touch skip point.
Step S105, if not, determining the touch point PNNot a touch skip point.
For example, if the step S104 determines that the first distance is greater than the first distance threshold, it may be determined that the touch point is a touch skip point.
Further, the touch skip point may be filtered. Or determining that a plurality of touch points behind the touch jumping point are also touch jumping points, and filtering the touch jumping points together. Therefore, the filtered touch points can be used for forming a touch track of the touch operation, and the touch operation is identified or processed according to the touch track.
In the embodiment of the application, the touch point P reported by the flexible sensor for the Nth time is obtainedNPosition information of (1) th touch point P and touch point P reported at the N-1 st timeN-1Can determine the touch point PNAnd the touch point PN-1And determining whether the first distance is greater than a first distance threshold, and if so, determining the touch point PNIs a touch skip point. By the method, the touch jumping points in the touch points reported by the flexible sensor can be determined, and the accuracy of touch jumping point identification is improved.

Similarly, the touch point P can be determinedN-2Position information (x) ofN-2，yN-2) And touch point PN-1Position information (x) ofN-1，yN-1) Determining a touch point PN-2To the touch point PN-1Vector v of2Vector v2Can be expressed as (x)N-1-xN-2，yN-1-yN-2). Wherein the vector v2The length of the touch point is the touch point PN-2And touch point PN-1Distance between, vector v2Is the touch point PN-2To the touch point PN-1In the direction of (a).
In fig. 3, vector v is shown1Sum vector v2Is merely illustrative.
First, according to the above embodiment, a touch point P can be determinedN-1And touch point PNIs greater than a first distance threshold. If the vector v is larger than the threshold value, the vector v can be further judged1And vector v2Whether the included angle therebetween is greater than a first included angle threshold. As shown in fig. 3, vector v1And vector v2The angle therebetween can be expressed as theta. If theta is larger than the first included angle threshold value, determining a touch point PNIs a touch skip point. Here, the first angle threshold may be preset or related to a touch trajectory of a touch operation, and is not limited herein, for example, θ may be 25 degrees or another value, and is not limited herein. If θ is less than or equal to the first angle threshold, the next touch point P can be obtainedN+1And steps S201 to S206 are repeatedly performed.
By the method, the accuracy of determining the touch jumping point can be further improved.
Some implementations for determining multiple touch skip points are described below.
Referring to fig. 4, fig. 4 is a flowchart illustrating a method for determining a touch skip point according to another embodiment of the present disclosure. As shown in fig. 4, the method includes at least the following steps.
Step S401, obtaining a touch point P reported by the flexible sensor for the Nth timeNPosition information of (1) th touch point P and touch point P reported at the N-1 st timeN-1N is an integer, and N is not less than 3.
Step S402, according to the touch point PNAnd the touch point PN-1Determining the touch point PNAnd the touch point PN-1A first distance therebetween.
Step S403, determining whether the first distance is greater than a first distance threshold.
Step S404, if yes, determining the touch point PNIs a touch skip point.
The specific implementation manner of steps S401 to S404 may refer to the description in the above embodiments, and is not described herein again.
Step S405, the touch point P is processedNAnd touch point P reported at the N +1 th timeN+1Touch point P reported to the N + M timesN+MA first set is formed.
And M is an integer greater than 1 and is determined by a preset time length T and a reporting period T of reporting the touch points by the flexible sensor.
For example, due to the characteristic of the phenomenon of the touch jumping, the touch jumping usually occurs in sequence. At the determined touch point PNAfter the touch jumping point, the touch point P can be determinedNAnd the touch points acquired for a plurality of times are also touch jumping points. Here, M touch points may be grouped into a set to determine whether all touch points in the set are touch skip points.
Illustratively, the value of M may be given by formula (3):
Figure PCTCN2017110812-APPB-000001
and (4) determining. Wherein, T is a preset duration, which may be a duration in which a common touch skip point occurs; t is flexible transmissionThe period of reporting touch points by the sensor, b is a constant and can be related to the number of touch points in touch operation. For example, b may take the value of 2 or 3, etc., and is not limited herein.
After M is determined, it is further determined whether the touch points in the first set are all touch skip points through the following steps.
Step S406, determining the touch point P reported at the N + i th time in the first setN+iTouch point P reported with the (N + i-1) th timeN+i-1Is less than a second distance threshold.
Wherein i is any integer in [0.6M, M ].
Illustratively, first the initial value of i may be determined as an upward integer of 0.6M. Determining a touch point PN+iAnd touch point PN+i-1Is less than a second distance threshold. The second distance threshold may be determined according to a distance value between two adjacent normal jumping points, which is not limited herein.
If touch point PN+iAnd touch point PN+i-1The distance between the touch points is greater than the second distance threshold value, the touch point P is indicatedN+iFor the touch jumping, the value of i may be added by 1, and step S406 is repeatedly executed until the value of i is equal to M. If the value of i is determined from the initial value to M that the distance between the previous touch points is greater than the second distance threshold, step S408 may be executed. Otherwise, step S407 is executed.
Step S407, if so, the touch point P is determinedNTo the touch point PN+i-1A second set is formed, the second set being a subset of the first set.
For example, if a touch point P is determined in step S406N+iAnd touch point PN+i-1The distance between the touch points is less than the second distance threshold, the touch point P may be touchedN+iIf the determination is false, the touch point P can be determinedN+iAnd determining the touch point as a normal touch point.

For example, if it is determined in step S406 that the distance between two adjacent touch points in the first set is not smaller than the second distance threshold, it may be determined that each touch point in the first set is a touch skip point. Touch points in the first set may thus be filtered.

Wherein the vector v4The length of the touch point is the touch point PN+i-2And touch point PN+i-1Distance between, vector v4Is the touch point PN+i-2To the touch point PN+i-1In the direction of (a).
Note that the vector v3Sum vector v4Is merely exemplary.
As shown in fig. 6, vector v3Sum vector v4The included angle therebetween can be represented as α, and it is determined α whether the included angle is greater than a second included angle threshold, where the second included angle threshold can be preset, and a value of the second included angle threshold is not limited herein.
If the value α is greater than the second angle threshold, step S509 may be executed, and if the value α is not greater than the second angle threshold, step S510 may be executed.
In step S509, if the determination result in step S508 is yes, it is determined that each touch point in the second set is a touch skip point.
