detailed description

The invention will be described in detail below with reference to the drawings in conjunction with the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict.

It is to be understood that the terms "first", "second" and the like in the specification and claims of the present invention are used to distinguish similar objects, and are not necessarily used to describe a particular order or order.

In the embodiment, a erroneous operation identification method is provided. FIG. 1 is a flowchart of a erroneous operation identification method according to an embodiment of the present invention. As shown in FIG. 1, the flow includes the following steps:

Step S102, detecting a first contact on the touch screen;

Step S104, determining whether the length of the minimum circumscribed square of the first contact falls within a preset length threshold, and determining whether the width of the minimum circumscribed square falls within a preset width threshold;

In step S106, if it is determined that the length does not fall within the preset length threshold, or if it is determined that the width does not fall within the preset width threshold, it is determined that the first contact is a contact generated by the erroneous operation.

Through the above steps, the area of the contact due to the erroneous operation is usually not regular and is larger than the area of the normal operation touch, and therefore, the minimum external square of the area of the contact generated by the erroneous operation is usually larger than the area of the normal operation touch. The minimum circumscribed square has a larger length or a larger width, and can determine whether the length and the width of the smallest circumscribed square of the detected first contact fall within a preset threshold, and determine the length of the minimum circumscribed square of the first contact and In the case where the width does not fall within the preset threshold, the first contact is determined as the contact resulting from the erroneous operation. It can be seen that the above steps solve the problem that the touch screen misoperation cannot be recognized, and the recognition of the touch screen misoperation is realized.

As an optional implementation manner, in step S104, the circumcircle of the minimum circumscribed square may be generated. In step S106, it may be determined whether the diameter of the circumscribed circle falls within a preset diameter threshold. Wherein, assuming that the preset diameter threshold is 2R, the preset length threshold is L, and the preset width threshold is W, then: R ² = (L/2) ² + (W/2) ² .

Optionally, the duration of the contact due to the erroneous operation is usually much greater than or far less than the duration of the normal operating contact. Therefore, when the minimum circumscribed square of the first contact falls within a preset threshold, Determining whether the first contact is a contact generated by an erroneous operation by determining the duration of the contact, for example, in the above step S106, it is also possible to determine that the length falls within a preset length threshold, and determine that the width falls. In the case of the preset width threshold, it is determined whether the trigger duration of the first contact falls within a preset duration threshold; and when it is determined that the trigger duration does not fall within the preset duration threshold, determining that the first contact is caused by a misoperation Contact. Through the above steps, the contacts generated by the erroneous operation are identified according to the contact area and the duration of the touch, which solves the problem that the erroneous operation cannot be recognized after the touch screen is locked, realizes the erroneous operation recognition after the touch screen is locked, and improves the misoperation. The accuracy.

Optionally, in order to make the setting of the preset length threshold and the preset width threshold more in line with the user's operating habits and improve the user experience, the preset length threshold and the preset width threshold may be calculated according to the daily operation habits of the user. For example, before the step S104, the plurality of second contacts on the touch screen may be detected when the touch screen is in the unlocked state; the length of the minimum circumscribed square of each of the plurality of second contacts and each contact may be acquired The minimum circumscribed square width; the maximum length of the minimum circumscribed square of each contact is determined to be a preset length threshold, and the maximum width of the minimum circumscribed square of each contact is determined to be a preset width threshold. It should be noted that, when the maximum length of the minimum circumscribed square of each contact and the maximum width of the minimum circumscribed square of each contact are obtained, the maximum length and the maximum width are set in a preset range. Within the range, the value outside the preset range will be considered as a value that does not meet the daily operation habits, and will be automatically discarded. Thus, the preset length threshold and the preset width threshold are obtained, and the preset length threshold and the preset width are also ensured. The rationality of the threshold.

Optionally, the minimum circumscribed square of the first contact may be established by making the direction of the coordinate axis of the edge of the minimum circumscribed square, or may be established at any angle. In the following, the case of establishing the coordinate axis direction of the edge of the minimum circumscribed square touch screen will be taken as an example. For the case of establishing any angle, the length and width of the minimum circumscribed square can be calculated by obtaining the coordinate values of the four vertices. Will not repeat them.

Optionally, in the case that the minimum circumscribed square of the first contact is established along the coordinate axis of the touch screen, in the above step S104, the maximum abscissa value, the minimum abscissa value, and the maximum ordinate of the first contact may be detected. a value and a minimum ordinate value; determining whether the length of the minimum circumscribed square falls within a preset length threshold by determining whether the first difference between the maximum horizontal coordinate value and the minimum horizontal coordinate value falls within a preset abscissa threshold, and Whether the second difference between the ordinate value and the minimum ordinate value falls within a preset ordinate threshold to determine whether the width of the minimum circumscribed square falls within a preset width threshold, wherein it is determined that the first difference does not fall into the preset In the case of the abscissa threshold, it is determined that the length does not fall within the preset length threshold, and in the case where it is determined that the second difference does not fall within the preset ordinate threshold, it is determined that the width does not fall within the preset width threshold. Through the above steps The length and width of the minimum circumscribed square can be easily obtained and compared with preset values to avoid complicated calculation process.

Optionally, in the foregoing step S102, whether the first contact is detected may be determined by determining whether the touch screen is in a locked state, thereby avoiding a normal operation (such as a palm gesture) performed by the user when the touch screen is not locked. Otherwise, it is considered to be a case of erroneous operation. Therefore, according to the above steps, the first contact on the touch screen can be detected in the case where it is determined that the touch screen is in the locked state.

Optionally, after the step S106, in the case that the first contact is determined to be a contact generated by the erroneous operation, the first contact may not be responded, and the prompt information of the erroneous operation may be displayed on the touch screen. The user can also be prompted by vibration.

Optionally, after the step S104, after determining that the length falls within the preset length threshold, and determining that the width falls within the preset width threshold, determining that the first contact is a contact generated by the normal operation, For normal operation of the contacts, you can operate according to the existing process.

In order to make the description of the embodiments of the present invention more clear, the following description and description are made in conjunction with the exemplary embodiments.

An alternative embodiment of the present invention provides a erroneous operation recognition method by which it is possible to determine whether a touch is an erroneous operation according to the size of the touch area (corresponding to the first contact) and the length of the touch time.

The normal touch unlocking is performed by the user touching the screen with a finger, and the size, shape and duration of the touch when the human finger touches the screen have obvious distinguishing features from the touch generated by the friction of the mobile phone in the pocket of the clothes or the trouser pocket.

1, the touch area size difference:

6 is a schematic diagram of a touch operation of a erroneous operation recognition method according to an alternative embodiment of the present invention. As shown in FIG. 6, the finger touch area is small, has a regular shape, is approximately square, and can be replaced by a larger square, which is called a reference. Square (for example: the reference square has a length of Lmax and a width of Wmax); the frictional touch area is much larger than the finger touch area, and the shape is irregular and randomly changes.

7 is a schematic diagram of a sliding touch of a erroneous operation recognition method according to an alternative embodiment of the present invention. As shown in FIG. 7, the finger touch area remains unchanged when the button is unlocked; the finger touch area can be regarded as a series of squares when the slide is unlocked. Superposition, the connection of the center can be considered as a straight line, and the touch area is still a square at any sampling time.

The touch area at the time of erroneous unlocking caused by the frictional contact may have a large touch area or a plurality of touch areas elsewhere in the screen, in addition to the trajectory that happens to cover the unlocked position or the slide unlocked.

2, the difference between the length of the touch:

The finger touch time is short when unlocking, and does not last too long from pressing to lifting, such as 1-2 seconds, the maximum time the user normally touches is called Tmax. The frictional touch lasts for a long time and will continue as long as it is placed in the pocket and the user's body is in motion.

Based on the above two differences, once the current touch area is completely within the reference square, no touch occurs outside the reference square, which can be initially considered as normal operation; optionally, the touch duration can be further determined, and the judgment can be improved. The accuracy of normal unlocking to avoid accidental unlocking.

The optional embodiments of the present invention are described below with reference to the accompanying drawings.

The length Lmax and the width Wmax of the touch area reference square used for the determination of the alternative embodiment of the present invention can be adjusted by different user samples, that is, the finger touch area of the user 1, 2, ..., n can be included in the length L1. , L2, ..., Ln, width n is W1, W2, ..., Wn within n squares, then Lmax = MAX (L1, L2, ..., Ln), Wmax = MAX (W1, W2, ..., Wn), MAX A function that takes the maximum value among n numbers.

The above may also include the case where the user has gloves. In summary, since the touch area generated by the rubbing touch is much larger than the touch area generated by the user's finger touch, it is always possible to find a reference square that can include different user finger touch areas. Moreover, the reference square size is still much smaller than the touch area produced by the frictional touch.

8 is a schematic diagram of a touch area of a erroneous operation recognition method according to an alternative embodiment of the present invention. As shown in FIG. 8, the reference square has a length Lmax and a width Wmax; and the normal operation area is surrounded by X1max, X1min, Y1max, and Y1min. Square area; the misoperation area is the area indicated by X2max, X2min, Y2max, Y2min.

FIG. 9 is a flowchart of a method for identifying an erroneous operation according to an alternative embodiment of the present invention. As shown in FIG. 9, the flow includes the following steps:

Step S902, when the mobile phone is in the state that the screen is on, when the mobile phone receives the reported touch event;

Step S904, determining whether the current screen is locked;

Step S906, if the unlock is not performed, continue to execute according to the original process;

Step S908, if it has been locked, acquire the X-axis minimum value Xmin and the maximum value Xmax, the Y-axis minimum value Ymin and the maximum value Ymax on the touch area, let ΔX=Xmax-Xmin, ΔY=Ymax-Ymin, and judge whether △ X<Lmax and ΔY<Wmax;

Step S910, when ΔX>Lmax or ΔY>Wmax, it can be considered as an erroneous operation, because the touch area is larger than the reference square at this time, and cannot be included by the reference square;

Step S912, when ΔX<Lmax and ΔY<Wmax are satisfied, the touch area may be included in a reference square having a length Lmax and a width Lmax, and determining whether the touch time is less than Tmax;

In step S914, when the touch time is not less than Tmax, it is determined to be an erroneous operation, otherwise it is determined to be a normal operation.

In summary, an erroneous operation recognition mode is added by the above-mentioned embodiment and the optional embodiment of the present invention. The optional embodiment of the present invention provides a erroneous operation recognition method, by determining whether the operation area falls into Refer to the square area and whether the operation duration is less than the preset duration to identify the erroneous operation on the touch screen, and determine that the operation area does not fall into the reference square area, or determine that the operation area falls into the reference square area but the operation duration is not less than In the case of a preset duration, the operation is recognized as an erroneous operation, and the problem that the erroneous operation cannot be recognized after the touch screen is locked is solved, and the erroneous operation recognition after the touch screen is locked is realized.

Industrial Applicability: As can be seen from the above description, the area of the contact that is generated by the erroneous operation of the present invention is generally irregular and larger than the area of the normal operation touch. Therefore, the minimum circumscribed square of the area of the contact generated by the erroneous operation is usually The length of the minimum circumscribed square of the area touched by the normal operation is larger or the width is larger, and the first contact can be judged by judging whether the length and the width of the smallest circumscribed square of the detected first contact fall within a preset threshold. In the case where the length and width of the smallest circumscribed square do not fall within the preset threshold, the first contact is determined as the contact resulting from the erroneous operation. It can be seen that the above steps solve the problem that the touch screen misoperation cannot be recognized, and the recognition of the touch screen misoperation is realized.

Obtaining a module, configured to obtain a length of a minimum circumscribed square of each of the plurality of second contacts and a width of a minimum circumscribed square of each of the contacts;

a second determining module, configured to determine a maximum length of a minimum circumscribed square of each contact as the preset length threshold, and determine a maximum width of a minimum circumscribed square of each contact The width threshold is optionally preset.
The apparatus of claim 8 wherein said determining module comprises:

a detecting unit configured to detect a maximum abscissa value of the first contact, a minimum abscissa of the first contact a value, a maximum ordinate value of the first contact, and a minimum ordinate value of the first contact;

a second determining unit, configured to determine whether the first difference between the maximum abscissa value and the minimum abscissa value falls within a preset abscissa threshold, and determine the maximum ordinate value and the minimum ordinate value Whether the second difference falls within a preset ordinate threshold;

If it is determined that the first difference does not fall within the preset abscissa threshold, it is determined that the length does not fall within the preset length threshold, and the second difference is determined In the case where the preset ordinate threshold is not dropped, it is determined that the width does not fall within the preset width threshold.
