Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The embodiment of the application provides a control touch processing method and device, a storage medium and electronic equipment. Any control touch processing device provided by the embodiment of the application can be integrated in electronic equipment, and the electronic equipment can comprise a mobile terminal, wearable equipment, a PC (personal computer) terminal with a touch screen, a robot with a touch screen and the like. The electronic device comprises a touch screen which can be used for receiving input numerical or character information.
Referring to fig. 1, fig. 1 is a schematic flow chart of a control touch processing method provided in an embodiment of the present application, and the control touch processing method is applied to an electronic device, where the control touch processing method includes steps 101 to 109, and specifically may be as follows:
101, when detecting that a key control arranged on the electronic device is touched, acquiring each touch point on a touch screen of the electronic device and a touch track formed by each touch point.
The key control is preset, and a sending control, a submitting control, a confirming control, a dialing control, a transfer control, a payment control, a recharging control and the like related to an application program on the electronic equipment are preset as the key control. For example, the control for sending short messages, the control for sending mails, the control for dialing telephone numbers, the control for charging the telephone fee on a certain treasure, the control for confirming payment and the like. The control may be in the form of a button, an icon, a label, a character, or a combination of the above-mentioned forms, for example, a combination of a character and a button, a combination of an icon and a character and a button, or the like.
And acquiring a key control set on the electronic equipment, and monitoring the key control to detect whether the set key control is touched. Specifically, whether an area where a key control piece is located on the touch screen is touched or not is detected, and if the area is touched, each touch point of the key control piece on the touch screen and a touch track formed by each touch point are obtained. It can be understood that a plurality of touch points are detected each time the touch screen is touched, and the touch points form a touch track according to the sequence of the touch points.
And 102, taking each acquired touch point as a current touch point.
And taking the acquired touch point as the current touch point when one touch point is acquired.
In some cases, step 102 includes: and when the touch points with the first preset number are detected to be acquired, taking each touch point acquired after the first preset number as the current touch point. It can be understood that the probability that the touch trajectory formed by the touch points in the first preset number is determined to be the backtracking trajectory is relatively low, and therefore, after the touch points in the first preset number are initially acquired, whether the touch trajectory formed by the touch points in the first preset number is the backtracking trajectory is not determined, so that the calculation amount is saved, and the power consumption of the electronic device is reduced. Wherein, the first preset number may be 10, etc.
And 103, detecting whether the current touch point is overlapped with a certain point except the current touch point in a current touch track formed by the current touch point.
If the touch points are collected very many and the touch points are dense, most of the points in the current touch track formed by the touch points are collected touch points, and thus, whether the current touch point is overlapped with a certain point except the current touch point in the current touch track formed by the current touch point or not is detected, and calculation can be performed approximately, that is, whether the current touch point is overlapped with a certain point in all the previously acquired touch points or not is detected. All the touch points acquired before refer to all the touch points except the current touch point. Each touch point has a corresponding coordinate, whether the current touch point is overlapped with one of all the previously acquired touch points or not is detected, namely whether the coordinate of the current touch point is the same as one of all the previously acquired touch points or not is detected, and if the coordinate of the current touch point is the same as one of all the previously acquired touch points, the overlapping is determined. The scheme for judging whether the trace is the backtracking trace is simple and easy to realize.
In other cases, detecting whether the current touch point coincides with a certain point in a current touch trajectory formed by the current touch point includes: and detecting whether the current touch point is on a line segment formed by any two adjacent previous touch points. Any two adjacent previous touch points refer to any two adjacent touch points other than the current touch point. It can be understood that the line segments formed by any two adjacent touch points are connected to form the current touch track. The method for judging whether the trace is the backtracking trace can improve the accuracy.
Specifically, a line segment formed by any two adjacent touch points is acquired, the two adjacent touch points are sequentially acquired according to the acquisition time sequence of the touch points, and the line segment formed by the two adjacent touch points is determined to detect whether the current touch point is on the line segment. The acquisition time sequence may be a time sequence of sequential acquisition, that is, from a touch point at which acquisition is started first, or a time sequence of reverse acquisition, that is, from a touch point before a current touch point. The order may also be random or may be in other orders.
Detecting whether a touch point is on a line segment formed by any two adjacent previous touch points may be calculated using cross multiplication. Assume that the current touch point is a and any two adjacent touch points are B and C. Detecting whether the current touch point A is on BC, it can be calculated by AB xBC. If AB xBC is equal to 0, and the abscissa of A satisfies min (x)B，xC)<＝xA<＝max(xB，xC) Wherein x isA，xB，xCRespectively A, B, C, determining that the current touch point A is on BC; if AB xBC is equal to 0, and the ordinate of A satisfies min (y)B，yC)<＝yA<＝max(yB，yC) Wherein, yA，yB，yCA, B, C, respectively, the current touch point a is determined to be on BC. After detection is carried out on a line segment, if the current touch point is on the line segment, detection is not carried out, and the current touch point is determined to be on the line segment formed by any two adjacent previous touch points, namely the current touch point is overlapped with a certain point in a current touch track formed by the current touch point; and if the current touch point is not on the line segment, determining whether the current touch point is on the line segment or not by detecting the next line segment, and thus, determining that the current touch point is on the line segment formed by any two adjacent previous touch points or until all the line segments formed by any two adjacent previous touch points are detected completely.
As shown in FIG. 2, which is an exemplary diagram of a touch trajectory, black dots in the diagram represent touch points. The track formed by the black dots is the touch track. Where a is the current touch point, B, C is two adjacent touch points, BC is a line segment formed by the two adjacent touch points, and 1 represents the start point of the touch trajectory. The locus formed by the gray dotted line corresponds to the locus of the key touch points shown in fig. 5.
If the current touch point is coincident with a certain point in a current touch track formed by the current touch point, executing step 104; if the current touch point is not coincident with any point in the current touch track formed by the current touch point, step 106 is executed.
And 104, determining the current touch track as a backtracking track.
And 105, determining that the touch of the key control is effective, and executing the operation corresponding to the key control.
It can be understood that if the key control is touched by mistake, the touch track corresponding to the touch by mistake does not form a backtracking track. If the key control is touched, the hand of the user can touch downwards and then is taken up, and a backtracking track can be formed in the process. And if the current touch track is the backtracking track, determining that the touch of the key control is effective. And after the touch of the key control is determined to be effective, the operation corresponding to the key control can be executed, and the operation is finished. Namely, the touch point and the touch track formed by the touch point are not continuously acquired, and whether the current touch point is on the current touch track or not is not continuously detected.
And 106, determining that the current touch track is not a backtracking track.
That is, if any point in the current touch trajectory formed by the current touch point and the current touch point is not overlapped, it is determined that the current touch trajectory is not the backtrack trajectory.
And 107, detecting whether the touch screen is released.
If the touch screen is released, the current touch of the key control is finished, step 108 is executed, and if the touch screen is not released, step 109 is executed.
And 108, determining that the touch of the key control is invalid.
That is, if the current touch point is not on the current touch track and the touch of the key control at that time is finished, it is determined that the touch of the key control is invalid.
109, acquiring the next touch point as the current touch point, and then executing step 103.
In the embodiment, each acquired touch point is taken as a current touch point in the process of touching the key control, whether the current touch track is a backtracking track or not is further determined by detecting whether the current touch point is overlapped with a certain point except the current touch point in the current touch track formed by the current touch point, and the touch of the key control is determined to be effective under the condition that the current touch track is the backtracking track. According to the method and the device, when the key control is detected to be touched by a user, operation corresponding to the key control is not executed, after the key control is touched, the touch point on the touch screen and the touch track formed by the touch point are detected, under the condition that the touch track is a backtracking track, the key control is determined to be effectively touched, and operation corresponding to the key control is executed again, so that mistaken touch of the user on the key operation can be avoided, and adverse effects caused by mistaken touch of electronic equipment are avoided.
In some cases, before step 101, further comprising: and setting key controls on the electronic equipment in advance. The key control can be set by the user when the application program is run, can be set when the electronic equipment is produced, and can also be set when the application program is issued.
The key control is set by a user as an example when the application program is run for simple explanation. As shown in fig. 3, on the interface for dialing a call, a "dial" control is set as a key control. Specifically, if the time for touching the "dial" control twice or continuously touching the "dial" control reaches the preset time, popping up an option: "dial", "set to key control", "cancel set to key control", etc. Touching the "set key control" option to set the "dial" control as the key control. For the convenience of the user, a special identifier may be displayed on the corresponding control set as the key control to identify that the control is set as the key control. Such as by displaying a small "off" word in the upper right corner of the control, or in some other manner.
Fig. 4 is another schematic flow diagram of a control touch processing method provided in an embodiment of the present application, which is applied to an electronic device, and the control touch processing method includes steps 201 to 210, which may specifically be as follows:
and 201, setting key controls on the electronic equipment in advance.
Specifically, setting key controls is shown in FIG. 3.
202, when detecting that a key control arranged on the electronic device is touched, obtaining key touch points on a touch screen of the electronic device and a touch track formed by the key touch points according to a preset interval.
And detecting whether an area where the key control piece is located on the touch screen is touched, and if the area is touched, acquiring key touch points on the touch screen of the electronic equipment according to a preset interval. It can be understood that when the key control is touched, a plurality of touch points for touching the key control on the touch screen of the electronic device are provided, and if each touch point needs to be acquired, a plurality of touch points need to be acquired. In practice, the positions of many touch points do not vary much. Therefore, key touch points on the touch screen of the electronic equipment are obtained according to the preset intervals, and whether a touch track formed by the key touch points is a backtracking track or not is judged by taking the key touch points as a reference.
The preset interval may be a preset time interval, for example, if the average time of touching the touch screen once is a seconds, the preset time interval may be set to a/50, and the like, for example, when the touch screen is detected, a first touch point is obtained as a key touch point, then a timer is started to detect whether the time reaches the preset time interval, and if the preset time interval is reached, the obtained touch point is used as the key touch point, and then the timer is started; the preset interval may also be a preset number of touch points, for example, when the touch screen is detected, acquiring a first touch point as a key touch point, counting the number of touch points, when the number of touch points reaches the preset number of touch points, acquiring a touch point after the number of touch points reaches the preset number of touch points, taking the touch point as the key touch point, and then counting the number of touch points again; the preset interval may also be a preset distance, for example, when a touch on the touch screen is detected, a first touch point is acquired as a key touch point, when a touch point is subsequently detected, if the distance between the touch point and a previous key touch point is greater than or equal to the preset distance, the touch point is acquired and is taken as the key touch point, and then the coordinate of the key touch point is taken as a reference to determine the distance to determine the next key touch point. The preset interval may also be other intervals, etc.
It can be understood that if each touch point is acquired and the touch trajectory is determined, a large amount of memory and calculation is required. And the key touch points are obtained according to the preset interval, and the backtracking track is judged according to the key touch points, so that the storage amount is less due to less key touch points, and the calculation amount is relatively less when the backtracking track is judged, so that the power consumption of the electronic equipment is reduced.
The touch track formed by the key touch points refers to a touch track formed by a plurality of key touch points according to the sequence of the key touch points.
And 203, taking each acquired key touch point as a current touch point.
And when one key touch point is acquired, taking the acquired key touch point as the current touch point.
In some cases, step 203, comprises: and when a second preset number of key touch points are detected, taking the key touch points acquired after the second preset number as current touch points. It can be understood that the probability that the touch trajectory formed by the key touch points in the second preset number obtained at the beginning is determined to be the backtracking trajectory is relatively low, and therefore, after the key touch points in the second preset number are obtained at the beginning, whether the touch trajectory formed by the key touch points is the backtracking trajectory is not judged, so that the calculation amount is further saved, and the power consumption of the electronic device is reduced. The second preset number may be the same as or different from the first preset number. Specifically, the second preset number is less than or equal to the first preset number. Wherein, the second preset number may be 3, etc.
And 204, detecting whether a line segment formed by the current touch point and a first touch point intersects with a touch track formed by all key touch points before the first touch point, wherein the first touch point refers to a key touch point adjacent to the current touch point.
The first touch point refers to a key touch point last to the current touch point, i.e., a key touch point adjacent to the current touch point. All the key touch points before the first touch point, namely all the key touch points except the current touch point and the first touch point in the current all the key touch points.
And the line segment formed by the current touch point and the first touch point is the line segment formed by the last key touch point. As shown in fig. 5, keypoint 7 and keypoint 8 form a line segment 78. The touch track formed by all the key touch points before the first touch point refers to the touch track obtained by all the key touch points except the current touch point and the first touch point according to the acquisition sequence of the key touch points. Touch trajectory 123456 formed by key touch point 1, key touch point 2, key touch point 3, key touch point 4, key touch point 5, and key touch point 6 in fig. 5.
Whether the line segment formed by the current touch point and the first touch point intersects with the touch track formed by all key touch points before the first touch point, namely whether the detection line segment 78 intersects with the touch track 123456 is detected.
Specifically, step 204 includes: and detecting whether the line segment formed by the current touch point and the first touch point is intersected with the line segment formed by any two adjacent key touch points before the first touch point.
There are several ways to detect whether the line segment formed by the current touch point and the first touch point intersects with the line segment formed by any two adjacent key touch points before the first touch point, and one of the ways will be described below:
