Detailed Description
Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
As shown in fig. 1, an embodiment of the present invention provides a method for performing a touch operation on a terminal, where the method may include the following steps S101 to S103:
step S101: receiving a first touch instruction triggered by two touch points on a page of the terminal, and calculating a first distance between the two touch points.
The two touch points may be two fingers of a user or two touch ends of a touch pen.
In order to facilitate calculation of the first distance, a rectangular coordinate system may be established on the page of the terminal, where the width direction of the terminal screen is taken as an x-axis, the length direction of the terminal screen is taken as a y-axis, and the center or one inflection point of the terminal screen is taken as an origin of coordinates. When two touch points trigger a first touch instruction on a page of the terminal, coordinates of the two touch points on a rectangular coordinate system can be respectively determined, for example, the coordinates of the two touch points a and B are respectively a (x) 1a ，y 1a )，B(x 1b ，y 1b ) Then, a first distance S1 between the two touch points a and B is calculated according to the coordinates of the two touch points a and B.
Step S102: and receiving a second touch instruction triggered by the two touch points on the page, and calculating a second distance between the two touch points.
When a second touch instruction triggered by two touch points on the page is received, the coordinates of the two touch points on the same rectangular coordinate system as the first touch instruction is triggered can be determined, for example, when the second touch instruction is triggered, the coordinates of the two touch points a and B are respectively a (x) when the second touch instruction is triggered 2a ，y 2a )，B(x 2b ，y 2b ) Then, a second distance S2 between the two touch points a and B is calculated from the coordinates of the two touch points a and B at this time.
It is understood that the first touch command and the second touch command may be triggered continuously or discontinuously. The continuously triggered first touch instruction and second touch instruction mean that two touch points do not leave the touch screen of the terminal between the input of the first touch instruction and the second touch instruction, when the two touch points contact the touch screen of the terminal for the first time, the two touch points are considered to input the first touch instruction, and the process that the two touch points slide on the touch screen of the terminal is considered to continuously input the second touch instruction. The first touch instruction and the second touch instruction triggered discontinuously mean that the two touch points leave the touch screen of the terminal after inputting the first touch instruction, and when the two touch points contact the touch screen again, the second touch instruction is input.
In order to ensure the accuracy of the touch operation, the method for performing the touch operation on the terminal provided by the embodiment of the invention further comprises the following steps: and calculating the second distance when the second touch instruction is received within a time threshold value from the receiving of the first touch instruction. That is, when the time interval between the receiving of the second touch instruction and the receiving of the first touch instruction is not greater than the time threshold, the second distance corresponding to the second touch instruction is calculated. Therefore, misoperation of the terminal caused by unconsciously inputting the touch instruction when a user browses a page can be avoided, and the accuracy of touch operation is improved.
Based on this, in the method for performing touch operation on a terminal provided in the embodiment of the present invention, before step S103, steps S201 to S205 shown in fig. 2 may be included:
step S201: receiving a first touch instruction triggered by two touch points on a page of the terminal, and calculating a first distance between the two touch points.
Step S202: and recording the trigger moment of receiving the first touch instruction.
Step S203: and judging whether the duration between the trigger time and the current time is smaller than a time threshold in real time, if so, executing the step S204, and otherwise, ending the current process.
Step S204: and monitoring whether a second touch instruction triggered by the two touch points on the page is received, if so, executing step S205, otherwise, executing step 203.
Step S205: and calculating a second distance between the two touch points when the second touch instruction is input.
Step S103: closing the page when an absolute value of a difference between the second distance and the first distance is greater than a distance threshold.
Taking two touch points as two fingers of a user as an example, the user can input a first touch instruction and a second touch instruction by contraction or amplification of the two fingers on a touch screen of the terminal, when the two fingers contract on the touch screen, it is indicated that a first distance corresponding to the first touch instruction is greater than a second distance corresponding to the second touch instruction, and when the two fingers amplify on the touch screen, it is indicated that the first distance corresponding to the first touch instruction is less than the second distance corresponding to the second touch instruction. And when the absolute value of the difference between the first distance and the second distance is greater than the distance threshold, closing the page of the terminal, namely, the user can perform contraction or amplification operation through the movement of two fingers on the touch screen of the terminal, so that the operation of closing the page of the terminal is realized.
When a user inputs a first touch instruction and a second touch instruction on different pages, the touch operation device provided by the embodiment of the invention can execute different operations on the terminal.
In order to prevent unintended erroneous operation by the user, the distance threshold may be set to a large value, for example, 200 pixels. In an embodiment of the present invention, when the page is an application page, the closing the page refers to exiting the application. That is to say, when the first touch instruction and the second touch instruction are input by the two touch points on the application page, and the absolute value of the difference between the second distance corresponding to the second touch instruction and the first distance corresponding to the first touch instruction is greater than the distance threshold, the finish () method may be invoked to exit the application to which the application page belongs, and return to the main interface of the terminal.
Of course, the closing page may also be set to return to the main interface of the application to which the application page belongs, that is, when the page is the application page, the closing page refers to returning to the main interface of the application. In addition, the closed page can also be set to be returned to the upper level page. The specific operation corresponding to closing the page may be customized by a user, for example, the first touch instruction and the second touch instruction triggered continuously are set to correspond to an operation of backing to the main interface of the application, the first touch instruction triggered continuously may also be set to correspond to an operation of backing to the main interface of the terminal, and the first touch instruction and the second touch instruction triggered discontinuously may also be set to correspond to an operation of backing to a previous page of the page.
The method for performing touch operation on a terminal provided by the embodiment of the present invention is described in detail below by taking a use process of the application M as an example. In this example, closing the page refers to returning to the main interface of the terminal. When a user uses the application M, firstly, an icon corresponding to the application M is clicked on a main interface of the terminal to enter the main interface of the application M, then, the main interface of the application M is searched through a keyword K, a page of the terminal jumps to a search result page corresponding to the keyword K, and when the user clicks an item N in the search result page, a detail page corresponding to the item N is entered. If the user wants to return to the main interface of the terminal from the detail page corresponding to the item N, the user can quickly return to the main interface of the terminal by inputting the first touch instruction and the second touch instruction.
In addition, the closing of the page may also refer to performing screen locking processing on the terminal. The user can pre-define that the screen locking operation of the terminal is executed when the first touch instruction and the second touch instruction of which the absolute value of the difference value of the input distances of any page is greater than the distance threshold value. It can also be defined that the screen locking operation is executed only when the first touch instruction and the second touch instruction are input into the specific page. For example, the method may be configured to call a LockNow screen lock command to execute the screen lock operation when the first touch instruction and the second touch instruction have the absolute value of the difference between the input distances of the main interface of the terminal or the main interface of the application greater than the distance threshold. Therefore, the screen locking operation of the terminal is achieved by receiving the touch instruction, a button screen locking mode in the prior art is replaced, and the improvement of user experience is facilitated.
After the screen is locked, the user can call the authentication interface by inputting the third touch instruction again, and the user enters the terminal main interface after passing the authentication. For example, if the user triggers the authentication icon of the terminal main interface by inputting the third touch instruction, the device for performing touch operation on the terminal according to the embodiment of the present invention may call the authentication interface according to the triggered authentication icon, and display the authentication interface, so as to receive the authentication information input by the user through the authentication interface, and then verify the authentication information, and when the verification passes, the main interface of the terminal may be displayed to the user.
In addition, when any page does not receive any touch instruction within a time threshold, a LockNow screen locking command can be called to execute screen locking and end the current process, so that illegal login is avoided, and the operation safety is improved.
In one embodiment, whether to perform the page closing operation is determined according to the first touch instruction and the second touch instruction, and the area operated by the first touch instruction and the second touch instruction may not be limited. In another embodiment, it may be limited that when the first touch command and the second touch command are operated on the predefined area, whether the page closing operation is performed is determined according to the first touch command and the second touch command. That is, if the first touch instruction and the second touch instruction are received within a predefined area of the page, the page is closed when an absolute value of a difference between the second distance and the first distance is greater than a distance threshold. The embodiment improves the accuracy of touch operation.
The following describes in detail a method for performing touch operation on a terminal according to an embodiment of the present invention, taking closing a page as an example of returning to a main interface of an application, where as shown in fig. 3, the method may include the following steps:
step S301: receiving a first touch instruction triggered by two touch points on an application page of the terminal, and calculating a first distance between the two touch points.
Step S302: and recording the trigger moment of receiving the first touch instruction.
Step S303: and judging whether the duration between the trigger time and the current time is smaller than a time threshold in real time, if so, executing step S304, otherwise, executing step S305.
Step S304: and monitoring whether a second touch instruction triggered by the two touch points on the application page is received, if so, executing step S306, otherwise, executing step 303.
Step S305: and carrying out screen locking processing on the terminal and ending the current process.
Step S306: and calculating a second distance between the two touch points when the second touch instruction is input.
Step S307: and judging whether the absolute value of the difference value between the first distance and the second distance is larger than a distance threshold value, if so, executing step S308, otherwise, executing step S303.
Step S308: and returning to the main interface of the application.
