The hardware structure and functions of the related devices of the present invention have been described in detail so far. Various embodiments of the present invention will be presented based on the above description.
First, the present invention provides a virtual keyboard generation system 100.
Fig. 2 is a block diagram of a virtual keyboard generation system 100 according to an embodiment of the present invention.
In this embodiment, the virtual keyboard generation system 100 includes a series of computer program instructions stored on the memory 11, which when executed by the processor 12, may implement the virtual keyboard generation operations of the embodiments of the present invention. In some embodiments, the virtual keyboard generation system 100 may be divided into one or more modules based on the particular operations implemented by the portions of the computer program instructions. For example, in fig. 2, the virtual keyboard generation system 100 may be divided into a definition module 101, a setting module 102, an acquisition module 103, a display module 104, and an adjustment module 105. Wherein:
the defining module 101 is configured to define a display area of the virtual keyboard, where the display area is configured as a text input area and a number input area, the text input area is configured with a plurality of keyboard configuration attributes, and each keyboard configuration attribute corresponds to a keyboard type.
In one embodiment, the virtual keyboard may be divided into two portions by the definition module 101. One part is a text entry field that can call up a virtual custom keyboard and the other part is a numeric entry field that can be used with other custom input interfaces. The text entry region may be configured by the definition module 101 to support HTML5 standard properties and cursor operations. The number input area may be configured by the definition module 101 to be suitable for a scenario of inputting a mobile phone number, a bank card number, a password, an amount of money, and the like. The text entry field may be designed to be introduced as a component by the definition module 101. The text input area may include a plurality of keyboard attributes, each of the keyboard attributes corresponding to a keyboard type. The definition module 101 can implement a plurality of keyboard types by newly creating or modifying the plurality of keyboard configuration attributes. The keyboard types comprise a numeric keyboard, a full text keyboard, a numeric keyboard, a text keyboard and the like. Because the user can newly create the keyboard configuration attribute through the definition module 101, the expansion of a new keyboard type can be supported, and because the virtual keyboard component is not a real input frame, a system keyboard cannot be triggered, and an embarrassing scene of two keyboards can be avoided.
The setting module 102 is configured to set at least one security rule for the plurality of keyboard configuration attributes, where the security rule at least includes one of a security prompt and a security string.
In one embodiment, the setting module 102 sets at least one security rule for a plurality of keyboard configuration attributes configured in the text input area. The security rules may be designed by the user or set according to an algorithm built into the virtual keyboard. The security rule may include a security prompt or a security string, which is not limited herein. If the security rule includes the security prompt, the user may know to input a specific character string on a certain keyboard layout of the virtual keyboard through the security prompt. For example, the security rules include the security prompt that certain specific letters are displayed in a different color on the keyboard layout of the virtual keyboard than on other keyboards. When the user sees that the display of certain letters on the virtual keyboard is different from other letters, he knows that certain letters are to be entered on the virtual keyboard based on the prompts for those letters. When the virtual keyboard is used each time, the symbols with different brightness shown by the safety prompt are different, the symbols are different in positions of the virtual keyboard and even the keyboard layout of the virtual keyboard, and therefore even if malicious software exists on a computer or a mobile device, the monitored personal information is not a valid password or account.
It should be noted that the above symbols are exemplified by alphabetic keyboards, and in different embodiments, the symbols with different brightness can also be numbers or other punctuation marks. The security rules may also include security strings, where a user sets a number of letters or numbers as the security strings, and in the keyboard layout randomly displayed on the virtual keyboard, the user knows to enter a specific string in the keyboard layout. It can be understood that the security rule may also be a calculation performed by matching an algorithm with the security string, and then inputting the calculation result into the virtual keyboard.
The obtaining module 103 is configured to respond to a trigger instruction for invoking the virtual keyboard, and obtain an attribute of an input box where a cursor is located.
In one embodiment, the interface displayed by the terminal (mobile phone, computer, etc.) often includes the input box, such as a search term input box of a search page, an input box in a chat interface in an instant messaging tool, a search term input box in an e-commerce application, and the like. Moreover, if the input box is included in the interface displayed by the terminal, the user may perform an operation on the input box, for example, click the input box. At this time, the obtaining module 103 responds to an operation instruction of the user for the input box, where the input box is a component of a browser or a client, and the obtaining module 103 may invoke the virtual keyboard, so that the terminal can pop up the virtual keyboard for the user to operate on the virtual keyboard to input information.
In one embodiment, the cursor corresponds to cursor configuration information. The cursor configuration information may be used to define a display effect and a cursor function of the cursor. The display effect of the cursor may include a cursor pattern and a blinking time. The cursor function may include functions of selecting, copying, pasting, etc. of the cursor.
In one embodiment, the attribute of the input box where the cursor is located may include a text attribute and a numerical attribute. When only numbers can be input in the input box, the attribute of the input box where the cursor is located can be defined as the input box for inputting the number attributes, such as a mobile phone number, a bank card number, an amount of money, and the like. When the input box in which the cursor is located can input numbers and/or characters, the attribute of the input box in which the cursor is located can be defined as a text attribute, such as a search page box, a chat interface input box, and the like.
The display module 104 is configured to display the text input area or the number input area according to an attribute of an input box where the cursor is located.
In an embodiment, the display module 104 displays the text input area or the number input area according to the attribute of the input box where the cursor is located, specifically as follows:
d1: when the attribute of the input box where the cursor is located is a numerical attribute, the display module 104 displays a numerical input area of the virtual keyboard, wherein the keyboard configuration attribute of the numerical input area is a numerical security keyboard;
d2: when the attribute of the input box where the cursor is located is a text attribute, the display module 104 displays the text input area of the virtual keyboard, and obtains the keyboard configuration attribute currently configured in the text input area, so as to call the keyboard type corresponding to the current keyboard configuration attribute.
In one embodiment, the keyboard corresponding to the number input area is a number safety keyboard. The digital security Keyboard includes a plurality of Keyboard layouts (Keyboard Layout). The numeric keys of each keyboard layout are arranged to be randomly displayed, so that the keyboard layouts in each occurrence are different. It can be understood that, since the virtual keyboard is a non-physical keyboard, the layout of the keyboard can be changed by programming, so that the arrangement of the keyboard of the virtual keyboard is different from that of the system keyboard.
In an embodiment, when the attribute of the input box where the cursor is located is a digital attribute, it indicates that the current cursor may be located in an input box for inputting a mobile phone number, a bank card number, a password, an amount, and the like, and at this time, the display module 104 displays a digital input area of the virtual keyboard and calls a digital security keyboard of the digital input area to perform digital input.
In an embodiment, when the attribute of the input box where the cursor is located is a text attribute, it indicates that the current cursor may be a search word input box located on a search page, an input box in a chat interface in an instant messaging tool, a search word input box in an e-commerce application, and the like, and at this time, the display module 104 displays a text input area of the virtual keyboard. It can be understood that, since the text input area has a plurality of keyboard configuration attributes, each of the keyboard configuration attributes corresponds to a keyboard type, the obtaining module 103 needs to further obtain the keyboard configuration attribute currently configured in the text input area, so as to call the keyboard type corresponding to the current keyboard configuration attribute to perform text input.
The adjusting module 105 is configured to detect and compare height information of a cursor in the input box with height information of the virtual keyboard, so as to adjust the height information of the virtual keyboard.
In one embodiment, the height information of the cursor in the input box is equal to the height information of the input box, and therefore, the inquired height information of the input box can be used as the height information of the cursor in the input box. The height information of the input box is the distance between the input box and the lower boundary of the current interface. The height information of the virtual keyboard is the distance between the upper boundary of the virtual keyboard and the lower boundary of the current interface.
In an embodiment, the adjusting module 105 detects and compares the height information of the cursor in the input box with the height information of the virtual keyboard to adjust the height information of the virtual keyboard, and the adjusting module 105 may adjust the height information of the virtual keyboard by:
s1: detecting height information of a cursor in the input box and height information of the virtual keyboard;
s2: comparing the height information of the cursor in the input box with the height information of the virtual keyboard;
s3: if the height information of the cursor in the input frame is not larger than the height information of the virtual keyboard, performing size reduction and bottom element opening optimization processing on the virtual keyboard;
s4: and if the height information of the cursor in the input box is larger than that of the virtual keyboard, optimizing the virtual keyboard.
In an embodiment, the adjusting module 105 may query the height information of the input box when the application renders the input box by calling a query interface provided by the application providing the input box, and use the queried height information of the input box as the height information of the cursor in the input box.
In an embodiment, the adjusting module 105 may call a query interface provided by the virtual keyboard to query the height information of the virtual keyboard.
In an embodiment, after the adjusting module 105 detects the height information of the cursor in the input box and the height information of the virtual keyboard, the adjusting module 105 may further compare the height information of the cursor in the input box with the height information of the virtual keyboard.
In one embodiment, when the height information of the cursor in the input box is not greater than the height information of the virtual keyboard, it indicates that if the virtual keyboard is directly displayed, the virtual keyboard will block the input box because the height of the virtual keyboard is higher than the height of the cursor in the input box, so that the user cannot browse the input information in the input box. Therefore, when the height information of the cursor in the input frame is not greater than the height information of the virtual keyboard, the adjusting module 105 needs to perform size reduction and bottom element unfolding optimization on the virtual keyboard to be displayed, so that the input frame is not shielded by the processed virtual keyboard.
In an embodiment, when the height information of the cursor in the input box is greater than the height information of the virtual keyboard, it indicates that the input box is not blocked by the virtual keyboard if the virtual keyboard is directly displayed, and the user can browse the input information in the input box. Therefore, when the height information of the cursor in the input box is greater than the height information of the virtual keyboard, the adjusting module 105 may directly display the virtual keyboard without performing size reduction and optimization of expanding bottom elements on the virtual keyboard to be displayed.
In an embodiment, the adjusting module 105 may determine target height information of a virtual keyboard to be displayed according to height information of a cursor in the input box; then, the adjusting module 105 configures the height information of the virtual keyboard to be displayed as the target height information according to the target height information. It is understood that the target height information is smaller than the height information of the cursor in the input box, and therefore, after the height information of the virtual keyboard is reduced to the target height information, the virtual keyboard will not block the input box.
In an embodiment, the adjusting module 105 may further determine target height information of the virtual keyboard to be displayed according to height information of a cursor in the input box; then, the adjusting module 105 determines the size reduction ratio according to the target height information; finally, the adjusting module 105 configures the display size of the virtual keyboard to be displayed as the size reduction ratio according to the size reduction ratio. It is understood that the target height information is smaller than the height information of the cursor in the input box, and the size reduction scale is smaller than 1. For example, the size reduction ratio is 85%, which means that the whole size of the virtual keyboard to be displayed needs to be reduced to 85% of the whole size of the original virtual keyboard, and the input box will not be obstructed by the virtual keyboard.
According to the virtual keyboard generation system, rich keyboard types can be realized through a plurality of keyboard configuration attributes, the expansion of new keyboard types is supported, the keyboard input is configured with safety rules, the safety is high, meanwhile, because the virtual keyboard input frame assembly is not a real input frame and does not conflict with the system keyboard, the scene that two keyboards appear at the same time can be avoided, the virtual keyboard can be perfectly matched with a page, and the page or the input frame cannot be extruded.
In addition, the invention also provides a virtual keyboard generation method.

The text entry region may be configured to support HTML5 standard properties and cursor operations. The digital input area can be configured to be suitable for scenes such as mobile phone numbers, bank card numbers, passwords, amount input and the like. The text entry field may be designed to be introduced as a component.

A plurality of keyboard types may be implemented by newly creating or modifying the plurality of keyboard configuration attributes. The keyboard types comprise a numeric keyboard, a full text keyboard, a numeric keyboard, a text keyboard and the like. Because the user can support the expansion of a new keyboard type by newly establishing the keyboard configuration attribute, and because the virtual keyboard component is not a real input frame, the system keyboard cannot be triggered, and the embarrassing scene of two keyboards can be avoided.
Step S402, at least one safety rule is set for the plurality of keyboard configuration attributes, wherein the safety rule at least comprises one of a safety prompt and a safety character string.
In one embodiment, at least one of the security rules is set for a plurality of keyboard configuration attributes configured for the text entry area. The security rules may be designed by the user or set according to an algorithm built into the virtual keyboard. The security rule may include a security hint or a security string, and is not limited herein. If the security rule includes the security prompt, the user may know to input a specific character string on a certain keyboard layout of the virtual keyboard through the security prompt. For example, the security rules include the security hint indicating that certain specific letters of the keyboard are displayed in a different color than other keyboards on a certain keyboard layout of the virtual keyboard. When the user sees that the display of certain letters on the virtual keyboard is different from other letters, he knows that certain letters are to be entered on the virtual keyboard based on the prompts for those letters. When the virtual keyboard is used each time, the symbols with different brightness shown by the safety prompt are different, the symbols are different in positions of the virtual keyboard and even the keyboard layout of the virtual keyboard, and therefore even if malicious software exists on a computer or a mobile device, the monitored personal information is not a valid password or account.
It should be noted that the above symbols are exemplified by alphabetic keyboards, and in different embodiments, the symbols with different brightness can also be numbers or other punctuation marks. The security rules may also include security strings, where a user sets a number of letters or numbers as the security strings, and in the keyboard layout randomly displayed on the virtual keyboard, the user knows to enter a specific string in the keyboard layout. It can be understood that the security rule may also be a calculation performed by matching an algorithm with the security string, and then inputting the calculation result into the virtual keyboard.
And S404, responding to a trigger instruction for calling the virtual keyboard, and acquiring the attribute of the input box where the cursor is positioned.
In one embodiment, the interface displayed by the terminal (mobile phone, computer, etc.) often includes the input box, such as a search term input box of a search page, an input box in a chat interface in an instant messaging tool, a search term input box in an e-commerce application, and the like. Moreover, if the input box is included in the interface displayed by the terminal, the user may perform an operation on the input box, for example, click the input box. At this time, in response to an operation instruction of the user for the input box, as a component of a browser or a client, may invoke the virtual keyboard, so that the terminal can pop up the virtual keyboard for the user to operate on the virtual keyboard to input information.
In one embodiment, the cursor corresponds to cursor configuration information. The cursor configuration information may be used to define a display effect and a cursor function of the cursor. The cursor display effect may include a cursor pattern and a blinking time. The cursor function may include functions of selecting, copying, pasting, etc. of the cursor.
In one embodiment, the attribute of the input box where the cursor is located may include a text attribute and a numerical attribute. When only numbers can be input into the input box, the attribute of the input box where the cursor is located may be defined as the input box for inputting the number attributes, such as a mobile phone number, a bank card number, an amount of money, and the like. When the input box in which the cursor is located can input numbers and/or characters, the attribute of the input box in which the cursor is located can be defined as a text attribute, such as a search page box, a chat interface input box, and the like.
