Embodiments of the invention

Referring to FIG. 1, an embodiment of an application deletion method in an embodiment of the present application may include:

Step S101: Monitor touch input on the touch screen of the target terminal.

Generally, pressure sensing or measuring components are disposed at the bottom of the touch screen to sense the strength of pressing the screen, thereby performing action feedback of different force dimensions such as tap, tap, and re-press, such as Apple's iPhone. The series is directly measured by the user's fingertips when pressed against the screen. After the glass screen is pressed and deformed, the pressure sensing device at the bottom of the screen measures the deformation of the glass to achieve the triggering mechanism of the user's different force.

For the sake of simple description, in this embodiment, the touch input of the user's finger on the touch screen is divided into two types, a click operation and a pressing operation, wherein the touch pressure value between the user's finger and the screen is small when the operation is clicked. When the pressing operation is performed, the touch pressure value between the user's finger and the screen is large, and the touch pressure value is greater than a preset pressure threshold, and the pressure threshold may generally be set to 100 Newtons.

Preferably, in the embodiment, the pressure threshold may be set according to the actual situation of the user, first prompting the user to perform multiple pressing operations on the touch screen, and then separately collecting the pressure values applied by the user each time, and finally taking the smallest one. A pressure value is used as the pressure threshold. For example, the user applies a pressure value of 100 Newtons in the first pressing operation, and a pressure value of 90 Newtons in the second pressing operation, and 110 Newtons in the third pressing operation. Then, the minimum value of 90 Newton is used as the pressure threshold. It should be noted that in the process of selecting, some values that deviate significantly from the average value need to be eliminated, for example, when the user performs the pressing operation multiple times in succession. The applied pressure value is about 100 Newtons, and a sudden pressure of 10 Newtons can be determined to be an abnormal value, which needs to be removed from the result.

Step S102: When the touch input is a pressing operation, acquire touch screen position coordinates corresponding to the pressing operation.

By calling the touch coordinate function provided by the system, the position coordinates of the touch screen corresponding to the pressing operation can be accurately obtained:

CGPoint point = [touch locationInView:[touch view]]

If x is used to represent the abscissa and y is the ordinate of it, then:

Int x = point.x;

Int y = point.y;

It should be noted that the coordinates of the coordinates here are in pixels.

Step S103: Determine a target application corresponding to the pressing operation according to the touch screen position coordinate.

On the screen of the target terminal, the icons of different applications occupy different areas. If the area of an application is IconArea (Xleft, Xright, Ytop, Ybottom), where Xleft is the leftmost side of the area occupied by the icon. On the abscissa, Xright is the abscissa of the rightmost area of the icon, Ytop is the ordinate of the top of the area occupied by the icon, and Ybottom is the ordinate of the bottom of the area occupied by the icon.

The touch screen position coordinates (x, y) corresponding to the pressing operation satisfy:

Xleft≤x≤Xright and Ybottom≤y≤Ytop

Then, it can be determined that the application is the target application corresponding to the pressing operation.

Step S104: Timing the duration of the pressing operation.

Step S105: When the time duration of the pressing operation is greater than a preset duration threshold, the target application is deleted from the target terminal.

The duration threshold may be determined according to the usage ratio of the target application. Specifically, the historical operation record of the target terminal in a preset statistical period is first acquired, and the historical operation record is used to count the historical operation record. The number of times the target application is used and the total number of uses of all applications, a first ratio of the number of uses of the target application to the total number of uses of all applications is calculated, and the duration threshold is determined according to the first ratio. The duration threshold is positively correlated with the first ratio, that is, the longer the first ratio is, the larger the duration threshold is. On the contrary, the smaller the first ratio is, the smaller the duration threshold is. For example, a reference duration of 20 seconds may be set, and the first ratio is used as a proportional coefficient of the reference duration. If the first ratio is 0.1, 20*0.1=2 seconds, that is, the duration threshold is determined to be 2 Seconds, if the first ratio is 0.3, then 20*0.3=6 seconds, that is, the duration threshold is determined to be 6 seconds. For an application, if the frequency of use is higher, the corresponding first ratio is larger, and the last determined duration threshold is also larger, and the user needs to press a longer time to delete it, thus avoiding Users accidentally delete some of their favorite applications.

The duration threshold may also be determined according to the proportion of download times of the target application. Specifically, first, a communication connection with a preset server is established, where the server is a server that provides an application download service. Querying the number of times the target application is downloaded and the total number of times all applications are downloaded, and calculating a second ratio of the number of times the target application is downloaded to the total number of times all applications are downloaded, according to the The second ratio determines the duration threshold. The duration threshold is positively correlated with the second ratio, that is, the second ratio is larger, the duration threshold is also larger. Conversely, the smaller the second ratio is, the smaller the duration threshold is. For example, a reference duration of 500 seconds may be set, and the second ratio is used as a proportional coefficient of the reference duration. If the second ratio is 0.01, then 500*0.01=5 seconds, that is, the duration threshold is determined to be 5 Seconds, if the second ratio is 0.004, then 500*0.004=2 seconds, that is, the duration threshold is determined to be 2 seconds. For an application, if the download frequency is higher, the corresponding second ratio is larger, and the last determined duration threshold is also larger, and the user needs to press a longer time to delete it, which can avoid Users accidentally delete some applications that are commonly used by most users.

Preferably, while the duration of the pressing operation is timed, the pressed application icon may be subjected to a color changing process or other identifying process, and a preset countdown progress bar is displayed on the current screen. When the progress bar is advanced to a preset position, an operation of deleting the target application from the target terminal is performed, so that on the one hand, a warning function for preventing misoperation can be performed, and on the other hand, the user can be given An intuitive experience. The advancement speed of the countdown progress bar is negatively correlated with the magnitude of the duration threshold, that is, the greater the duration threshold, the slower the advancement speed of the countdown progress bar, and vice versa, the smaller the duration threshold The progress of the countdown progress bar is faster.

Preferably, the user can also set whether to enable the function of the pressure sensitive touch deletion application in the user setting or the system setting of the terminal in advance. If the function of the pressure sensitive touch deletion application is not enabled, the application is not deleted according to the pressing operation. At this time, the operation pressed by the user can be converted into a normal click operation to perform an application opening operation, or the user is prompted to enable the pressure sensitive touch function, or no operation is performed, if the function of the pressure sensitive touch deletion application is enabled, the pressing operation is performed. When the timing is longer than the duration threshold, the corresponding application is deleted. In this embodiment, the function of the pressure sensitive touch deletion application of the terminal is enabled by default.

Preferably, the user may be provided with an opportunity to cancel the deletion operation, that is, setting a preset folder, and when executing the process of deleting the application, the application is not actually deleted, but only the application is moved to the In the folder, if the user needs to use the application within a preset time period (for example, one day), the application can be selected in the folder to restore the use of the application, if the user is preset The recovery operation was not performed during the time period, and the application was completely removed.

In summary, the embodiment of the present application firstly monitors a touch input on a touch screen of a target terminal, and when the touch input is a press operation, acquires a touch screen position coordinate corresponding to the pressing operation. The pressing operation is a touch input with a touch pressure value greater than a preset pressure threshold, determining a target application corresponding to the pressing operation according to the touch screen position coordinate, and then timing the duration of the pressing operation And when the time duration of the pressing operation is greater than a preset duration threshold, deleting the target application from the target terminal. For the user, only the touch pressure greater than the pressure threshold is applied to the application icon to be deleted and the duration is longer than the duration threshold, so that the deletion of the application can be realized, which greatly simplifies the operation process.

In the above embodiment, if the user's terminal is borrowed by another user, other users are not familiar with the setting of the terminal, and it is likely that the application icon is mistakenly pressed for a long time without knowing the application. In order to avoid this situation, on the basis of the above embodiments, an optimization scheme as shown in FIG. 2 can also be adopted:

Step S201: Monitor touch input on the touch screen of the target terminal.

Step S202: When the touch input is a pressing operation, acquiring touch screen position coordinates corresponding to the pressing operation.

Step S203: Determine a target application corresponding to the pressing operation according to the touch screen position coordinates.

Step S204: Timing the duration of the pressing operation.

The process of the step S201 to the step S204 is similar to the process of the step S101 to the step S104 in the foregoing embodiment. For details, refer to the description in the previous embodiment.

Step S205: When the time duration of the pressing operation is greater than a preset duration threshold, the pressed fingerprint information corresponding to the pressing operation is acquired.

It should be noted that the manner of obtaining fingerprint information in this embodiment is different from the manner in which most terminals currently obtain fingerprint information. At present, most terminals have an area for obtaining fingerprint information on the bottom or the back of the screen. The user needs to press a finger on the area to perform fingerprint recognition. In this embodiment, the fingerprint sensor that collects the fingerprint information is disposed in the touch screen of the target terminal, and when the user performs a pressing operation on the screen, the fingerprint information can be collected.

Step S206: Extract a feature vector in the pressed fingerprint information.

Firstly, the pre-processing of pressing fingerprint information is enhanced, refined and binarized, the interference of various noises is removed, the ridge structure of the fingerprint is restored, and the texture is accurate and clear, so that subsequent operations can be performed correctly and effectively. Then, the information template of the detailed feature points is extracted from the pre-processed pressed fingerprint information, and the pseudo-detail points are removed from the extracted minutiae points according to the positional rule of the pseudo-detail points, and the gradient amplitude values of the respective detailed feature points are calculated. And gradient direction. Based on the distribution of the feature points, the detailed feature points can be divided into several blocks, and the gradient direction is equally divided into multiple direction intervals. The weights of the detailed feature points in each block are calculated to obtain a multidimensional The vector is the feature vector of the block, and finally the feature vectors of the respective blocks are merged into the feature vector of the pressed fingerprint information by means of sequential connection.

Step S207: Calculate a matching degree between the feature vector in the pressed fingerprint information and a preset standard feature vector.

If x is used to represent the feature vector in the pressed fingerprint information, the standard feature vector is represented by y, the dimensions of both are N, and the matching degree of the two is represented by sim(x, y), then:

Sim(x,y)=1/{1+[(x ₁ -y ₁ ) ² +(x ₂ -y ₂ ) ² +...+(x _i -y _i ) ² +...+(x _N -y _N ) ² ] ^1/2 }

Where x _i represents the ith dimension of the feature vector in the pressed fingerprint information, and y _i represents the ith dimension of the standard feature vector.

Step S208: Determine whether the matching degree is less than a preset matching degree threshold.

If the matching degree is less than the preset matching degree threshold, step S209 is performed, and if the matching degree is greater than or equal to the matching degree threshold, step S210 is performed.

Step S209, prompting the current user that the current user does not have the program deletion permission.

Since the current user does not have the program deletion permission, the operation of deleting the target application from the target terminal will not be performed at this time.

Step S210: deleting the target application from the target terminal.

On the basis of the previous embodiment, this embodiment adds a process of authenticating user rights through fingerprint information. When the user terminal is borrowed by other users, even if other users are not familiar with the setting of the terminal, the unknowing is unknown. In the case of a long time, the icon of an application is pressed for a long time, but the deletion command does not take effect due to the limitation of the user authority, which reduces the occurrence of a misoperation when the user terminal is borrowed by another user. Moreover, in this embodiment, it is not necessary to perform special fingerprint information collection, but the user performs the pressing operation on the screen, and the fingerprint information is collected by the fingerprint sensor disposed in the touch screen, thereby greatly improving the user experience.

It should be understood that the size of the serial number of each step in the above embodiments does not mean the order of execution, and the order of execution of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present application. .
