These drawings and the written description are not intended to limit the scope of the disclosed concepts in any way, but rather to illustrate the disclosed concepts to those skilled in the art by reference to specific embodiments.
Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.
The keyboard is a main device for a user to interact with the electronic product, and the user presses each key on the keyboard to enable the electronic product to execute a function corresponding to the key.
The actual key value of a key is generally a character string for distinguishing each key, and is a fixed value set by a keyboard manufacturer when the keyboard leaves the factory. In the existing triggering process of key values of keys, when a user presses a key, a keyboard can send a real key value corresponding to the key to a port of an electronic product, so that the electronic product can monitor a keyboard event triggered by the user and send the received real key value to application software or an application program carried by the electronic product. The corresponding operations and functions are then performed by the application software or application program based on the received actual key values.
However, due to different usage habits of users, the existing key value triggering manner cannot meet the personalized usage requirements of the users, for example:
when a certain program in the electronic product is set to execute the operation a when the true key value corresponding to the left Ctrl key is received, that is, the user can only trigger the left Ctrl key to cause the program to execute the operation a. And the usage habits of the users are different, when the user wants to use other keys, such as a left Shift key, to make the program execute the operation a, the related files in the program system configuration need to be modified. In many cases, such as a system based on an engineering singlechip, the program does not provide the modification function, so a new trigger mode of key values in the keyboard is needed to meet the use requirement of the user.
The following describes the technical scheme of the present application and how the technical scheme of the present application solves the above technical problems in detail with specific embodiments. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.
Example 1
Fig. 1 is a flowchart of a method for triggering a key value according to an embodiment of the present invention.
As shown in fig. 1, the triggering method of the key value includes:
step 101, judging whether a target key triggered by a user has a virtual key value according to a pre-stored virtual key value function of each key;
if yes, go to step 102; if not, step 103 is performed.
102, obtaining a virtual key value of a target key according to a virtual key value function of the target key, and sending the virtual key value to an electronic product so that the electronic product can execute corresponding operation according to the virtual key value of the target key;
step 103, the real key value of the target key is sent to the electronic product, so that the electronic product executes corresponding operation according to the real key value of the target key.
It should be noted that, the execution main body of the key value triggering method provided in the first embodiment of the present invention is a key value triggering device, and the key value triggering device may be installed in each electronic product under each operating system, or may be independently installed in a local device and interact with an electronic product disposed at a remote end. The electronic products include, but are not limited to, smart phones, smart terminals with physical or virtual keyboards, desktop computers, tablet computers, etc. In addition, the program loaded in the key value triggering device can be written in languages such as C/C++, java, shell or Python.
Specifically, the triggering device of the key value determines whether the target key with the key pressing event has the corresponding virtual key value according to the pre-stored virtual key value function of each key. The virtual key value function may specifically be a function expression, a calculation expression or a conversion expression for representing a correspondence between a real key value and a virtual key value of a key, which is generally preset by a user, and the setting mode may be multiple: setting a virtual key value function for each key, setting the function value of the virtual key value function of the key needing to trigger the virtual key value function as a virtual key value, and setting the function value of the virtual key value function of the key needing not to trigger the function as null; or, the virtual key value function is set only for the key which needs to trigger the virtual key value function, and the key which does not need to trigger the function does not set the virtual key value function. Of course, other arrangements may be used, and the invention is not limited in this regard.
In addition, the virtual key value of the key is similar to the representation mode of the real key value of the key but different in representation content, and the specific key value can be set by the user according to the actual situation, so that the invention is not limited. Taking the foregoing left Ctrl key and the left Shift key as examples, the real key value of the left Ctrl key is 0x11, the real key value of the left Shift key is 0x10, if the user wants to implement the function of the left Ctrl key by using the left Shift key, a corresponding virtual key value function needs to be set for the left Shift key, so that when the left Shift key is triggered, the virtual key value 0x11 of the left Shift key is sent to the port of the electronic product.
Meanwhile, as can be seen, the virtual key value function of each key can be preset by a user and stored in the triggering device of the key value, and the virtual key value function can be stored in a virtual key value function list mode, namely, the real key value and the virtual key value function of each key with the virtual key value are in one-to-one correspondence and are stored; the method can also adopt a database form for storage, namely a plurality of virtual key value functions are stored in the same function library, and are queried and called through a preset query and call mode. That is, according to the pre-stored virtual key value function of each key, it can be determined whether the target key has the corresponding virtual key value.
Then, when the target key is determined to have a virtual key value, the virtual key value of the target key can be determined according to a virtual key value function of the target key, and the virtual key value of the target key is sent to the electronic product so that the electronic product can execute corresponding operation according to the virtual key value of the target key; and when the target key does not have the virtual key value, transmitting the real key value of the target key to the electronic product so as to execute corresponding operation by the electronic product according to the real key value of the target key.
In the prior art, the operation of sending key values to an electronic product is generally implemented by a main thread: when a user presses a key, the trigger device establishes a main thread to send a real key value corresponding to the key to a port of the electronic product through the main thread, so that application software or an application program in the electronic product executes corresponding operation and function according to the real key value.
In the embodiment of the application, because whether the target key has the virtual key value is judged, and the virtual key value or the real key value is sent to the electronic product according to the judging result, when the target key has the virtual key value, a virtual key value sending sub-thread is also established so that the virtual key value of the target key can be sent to the electronic product through the virtual key value sending sub-thread. When the target key has a virtual key value, the target key is sent to the electronic product through a virtual key value sending sub-thread so that the electronic product can execute corresponding operation according to the virtual key value; when the target key does not have the virtual key value, the real key value of the target key is sent to the electronic product through the main thread, so that the electronic product can execute corresponding operation according to the real key value.
Preferably, under the condition that the target key has a virtual key value, the virtual key value sending sub-thread can intercept the real key value sent by the main thread, so that the electronic product only receives the virtual key value; or the virtual key value sending sub-thread sends a virtual key value and a real key value invalidation instruction of a target key to the electronic product at the same time, so that the electronic product only executes corresponding operation according to the virtual key value under the condition that the electronic product receives the virtual key value of the target key and the real key value of the target key at the same time; or intercepting the sending operation of the real key value through the virtual key value sending sub-thread, so that the electronic product only receives the virtual key value and executes corresponding operation according to the virtual key value.
Taking the aforementioned application scenario as an example: in the prior art, when a program in an electronic product receives a real key value 0x11 of a left Ctrl key, an operation A is executed; in the embodiment of the invention, a user can pre-store a virtual key value function X of a left Shift key in a trigger device of a key value, and configure the virtual key value of the left Shift key to be the same value as a real key value of a left Ctrl key, namely 0X11 by utilizing the virtual key value function X. Once the user triggers the left Shift key, the triggering device of the key value judges and obtains the conclusion that the left Shift key has a virtual key value, then, the triggering device obtains the virtual key value 0x11 of the left Shift key according to the left Shift key, and directly sends the virtual key value 0x11 to the program of the electronic product, so that the program in the electronic product executes corresponding operation according to 0x11, namely, the function that the user triggers the left Shift key to realize the corresponding operation of the left Ctrl key is completed, and of course, in the process, the triggering device sends the virtual key value 0x11 of the left Shift key to the electronic product, and simultaneously, can also send a real key value invalidation instruction of the left Shift key to the electronic product, so that the electronic product executes corresponding operation only according to 0x11 based on the real key value invalidation instruction; or in the process, the triggering device intercepts the sending operation of the real key value of the left Shift key, so that the electronic product only receives the virtual key value 0x11 of the left Shift key, and executes corresponding operation according to 0x11. Correspondingly, when the user triggers the left Ctrl key, under the condition that the left Ctrl key is judged to have no virtual key value, the triggering device directly sends the real key value 0x11 of the left Ctrl key to the program of the electronic product, so that the program of the electronic product can execute corresponding operation according to 0x11, namely, when the user triggers the left Ctrl key, the function of the operation corresponding to the left Ctrl key is realized.
In other words, in the above embodiment, the user may trigger the left Ctrl key or the left Shift key, and the program of the electronic product executes the corresponding operation according to 0x11 and implements the corresponding function, so that the manner can facilitate the users with different operation habits to perform the key operation, thereby satisfying the user requirement, and also solving the problem in the prior art that the key function cannot be effectively expanded due to the fact that the key values are all fixed real key values preset in factory.
In an optional implementation manner, when the electronic product runs, the triggering device based on the key value of the electronic product can monitor a keyboard event, lock the current display window of the electronic product when the key pressing event appears, and execute the virtual key value function according to the prestored keys to judge whether the target key triggered by the user has the virtual key value; and when the key bounce event is monitored, sending the virtual key value or the real key value of the target key to the electronic product, and releasing the current display window.
Specifically, the keyboard event may include a key press event and a key pop event, where the key press event may specifically refer to that a user clicks a virtual keyboard on a touch screen and triggers a key instruction on the virtual keyboard, and may also refer to that the user presses a key in an entity keyboard or a key in an entity input device through a physical pressing manner; correspondingly, the key bounce event may specifically be an instruction triggered by a user after the key press event to enable keys in input devices such as a virtual keyboard or an entity keyboard to return to an original state, which may be implemented by a key position where a finger of the user leaves the virtual keyboard, or may be implemented by self-bouncing and homing of the keys when the finger of the user leaves the keys of the entity keyboard or the entity input device.
Then, when the triggering device of the key value monitors the key pressing event triggered by the user, the current display window is locked until the key bouncing event is monitored, and the current window is released. That is, in the current display window locking state, the triggering device cannot monitor the key pressing event of other keys, that is, the triggering device can only determine whether one target key has a virtual key value at a time, and in this way, confusion caused by determining whether a plurality of keys all have virtual key values at the same time is avoided.
According to the triggering method of the key values of the keys, whether the target key triggered by the user has the virtual key value is judged according to the virtual key value function of each pre-stored key; under the condition that a target key triggered by a user has a virtual key value, acquiring the virtual key value of the target key, and sending the virtual key value to an electronic product so that the electronic product executes corresponding operation according to the virtual key value of the target key; and under the condition that the target key triggered by the user does not have the virtual key value, transmitting the real key value of the target key to the electronic product so as to execute corresponding operation by the electronic product according to the real key value of the key. By the mode, the key value of the keyboard is effectively expanded, and the use requirement of a user is met.
Example two
On the basis of the first embodiment, fig. 2 to fig. 4 are respectively three key value triggering methods according to the present invention in order to further illustrate the key value triggering method according to the present invention.
Fig. 2 is a flow chart of a key value triggering method according to a second embodiment of the present invention. As shown in fig. 2, the method includes:
step 201a, obtaining a real key value of a target key triggered by a user;
step 202a, determining whether there is a virtual key value function corresponding to the real key value of the target key.
If not, the target key does not have the virtual key value, and step 205a is executed; if yes, go to step 203a.
And 203a, calling a virtual key value function corresponding to the real key value of the target key, obtaining a function value, and judging whether the function value is null.
If yes, the target key does not have a virtual key value, and step 205a is executed; if not, the target key has a virtual key value, and step 204a is performed.
Step 204a, determining the obtained function value as a virtual key value of the target key, and sending the virtual key value to an electronic product so that the electronic product can execute corresponding operation according to the virtual key value.
Step 205a, the real key value of the target key is sent to the electronic product, so that the electronic product performs a corresponding operation according to the real key value of the target key.
It should be noted that, similar to the embodiment, the execution body of the key value triggering method provided in the second embodiment is a key value triggering device, and the key value triggering device may be installed in each electronic product under each operating system, or may be independently installed in a local device and interact with an electronic product disposed at a remote end. The electronic products include, but are not limited to, smart phones, smart terminals with physical or virtual keyboards, desktop computers, tablet computers, etc. In addition, the program loaded in the key value triggering device can be written in languages such as C/C++, java, shell or Python.
Specifically, the triggering device of the key value determines whether the target key with the key pressing event has the corresponding virtual key value according to the pre-stored virtual key value function of each key. The virtual key value function may specifically be a function expression, a calculation expression or a conversion expression for representing a correspondence between a real key value and a virtual key value of a key, which is preset by a user, and the setting mode may be multiple: setting a corresponding virtual key value function for each key, wherein the function value of the virtual key value function of the key needing to trigger the virtual key value function is set as a virtual key value, and the function value of the virtual key value function of the key needing not to trigger the function is set as null; or, the virtual key value function is set only for the key which needs to trigger the virtual key value function, and the key which does not need to trigger the function does not set the virtual key value function. Of course, other arrangements may be used, and the invention is not limited in this regard.
Unlike the first embodiment, in the method for triggering a key value of a key shown in fig. 2, according to a pre-stored virtual key value function of each key, whether the target key triggered by the user has a virtual key value is determined, specifically, the method may include steps 201a to 203a, and the two steps of determining whether the target key has a virtual key value function and whether the function value is null are performed, so that whether the virtual key value function is triggered or not can be determined by the embodiment shown in fig. 2 no matter which of the two setting manners is adopted.
Specifically, after the user triggers the target key, first, the triggering device will acquire the real key value of the target key, and the acquiring manner is similar to the prior art, which is not described in detail in this embodiment. Then, the triggering device of the key value of the key determines whether a virtual key value function corresponding to the real key value of the target key exists according to the virtual key value function of each pre-stored key. When the virtual key value function corresponding to the target key exists, the virtual key value function is called to obtain a function value, and whether the function value is null is judged, so that when the fact that the corresponding virtual key value function exists in the target key and the function value is not null is determined, the triggering device sends the virtual key value to the electronic product, and otherwise, the triggering device sends the real key value of the target key to the electronic product. Therefore, in this embodiment, by determining whether the corresponding virtual key value function exists and whether the function value of the virtual key value function is null, whether the virtual key value of the key is triggered is determined, so that accuracy of determination is improved, and misoperation caused by misdetermination is avoided.
Unlike the previous embodiments, fig. 3 and 4 provide two alternative embodiments, respectively, for the way in which the virtual key value function is set by the user:
fig. 3 is a flowchart of another key value triggering method according to the second embodiment of the present invention. As shown in fig. 3, the method includes:
step 201b, obtaining a real key value of a target key triggered by a user.
Step 202b, calling a virtual key value function corresponding to the real key value, obtaining a function value, and judging whether the function value is null.
If the function value is null, the target key does not have a virtual key value, and step 204b is executed; if the function value is not null, the target key has a virtual key value, and step 203b is executed.
Step 203b, determining the obtained function value as a virtual key value of the target key, and sending the virtual key value to an electronic product, so that the electronic product can execute corresponding operation according to the virtual key value.
Step 204b, the real key value of the target key is sent to the electronic product, so that the electronic product executes corresponding operation according to the real key value of the target key.
Unlike the foregoing embodiment, this embodiment shown in fig. 3 is particularly directed to the case where one virtual key function is set for each key, in which case the function value of the virtual key function of the key that needs to trigger the virtual key function is set to a virtual key value, and the function value of the virtual key function of the key that does not need to trigger the function is set to null, that is, the virtual key function is set in such a manner that the virtual key functions of all keys are locally pre-stored.
For example, in the process of setting the virtual key functions, the user can edit the virtual key value functions of each key one by one at the setting interface or the designated interface, and the virtual key value functions can be specifically pre-stored in the local function library, and the user only needs to call and store the settings according to the needs.
Further, according to different demands of users, the virtual key value functions are generally divided into two types, wherein one type corresponds to the virtual key value function with the virtual key value function, namely, the function value obtained by calling and running the virtual key value function is the virtual key value expected by the user; the other class corresponds to virtual key functions without virtual key functions, i.e. the function values obtained by calling and running such virtual key functions should be null. In the process of setting the virtual key value functions by the user, if the user does not finish setting the virtual key value functions of all keys, the triggering device can correspondingly prompt the user to remind the user of finishing setting; further, after the device alerts, if the user still does not wish to continue to set the virtual key value functions of some keys, the triggering device may default to the virtual key value functions that the user does not need to trigger the virtual key value functions of some keys, where the triggering device will directly set the virtual key value functions of some keys as those virtual key value functions with null function values.
Therefore, in this embodiment, the virtual key function corresponding to the real key is called to obtain the function value, and whether the function value is empty is determined, so as to trigger the virtual key function. Compared with the embodiment shown in fig. 2, the calling speed and the triggering speed are faster, and the triggering efficiency is improved.
Fig. 4 is a flowchart of a triggering method of a key value according to a second embodiment of the present invention. As shown in fig. 4, the method includes:
step 201c, obtaining a real key value of a target key triggered by a user;
step 202c, inquiring whether a virtual key value function corresponding to the real key value is pre-stored locally.
If not, the target key does not have the virtual key value, and step 204c is executed; if so, the target key has a virtual key value, and step 203c is performed.
Step 203c, calling a virtual key value function corresponding to the real key value, obtaining a function value, determining the obtained function value as the virtual key value of the target key, and sending the virtual key value to an electronic product so that the electronic product can execute corresponding operation according to the virtual key value.
Step 204c, the real key value of the target key is sent to the electronic product, so that the electronic product executes corresponding operation according to the real key value of the target key.
Unlike the foregoing embodiment, the embodiment shown in fig. 4 is directed to a manner in which the user sets the virtual key function to the key that needs to trigger the virtual key function, and the key that does not need to trigger the function does not set the virtual key function. In this case, the key that needs to trigger the virtual key function has a virtual key function pre-stored locally, while the key that does not need to trigger the function does not have any virtual key function pre-stored locally. That is, at least a part of virtual key value functions of the keys are locally pre-stored.
For example, in the process of setting the virtual key function, the user can edit the virtual key function of the key with the virtual key function one by one in the setting interface or the designated interface, and the virtual key function can be pre-stored in the local function library, so that the user only needs to call and store the setting according to the requirement.
Further, unlike the foregoing embodiments, the virtual key function in the present embodiment is a function having a virtual key function, that is, a function value obtained by calling and running such a virtual key function should be a virtual key desired by a user. In the process of setting the virtual key value function by the user, if the user finishes setting the virtual key value function of part of keys, the user can be correspondingly prompted to avoid missing the setting of the keys by the user; further, after the device alerts, if the user still does not wish to continue to set the virtual key function of some keys, the default may be that the user does not need to trigger the virtual key function for these keys, and no other processing is performed.
Therefore, in this embodiment, whether the virtual key value function corresponding to the real key value is locally pre-stored is queried, and the virtual key value function corresponding to the real key value is directly called to obtain the function value, so that the obtained function value is determined as the virtual key value of the target key. Compared with the embodiment shown in fig. 2, the calling speed and the triggering speed are faster, the triggering efficiency is improved, and compared with the embodiment shown in fig. 3, the method occupies smaller storage space and is more suitable for electronic products with weaker processing capacity and storage capacity.
Optionally, on the basis of the implementation manners shown in fig. 2 to fig. 4, the triggering method further includes, as in the first embodiment, the following steps: monitoring for keyboard events; correspondingly, when a key pressing event is monitored, locking a current display window, and judging whether a target key triggered by a user has a virtual key value according to a pre-stored virtual key value function of each key; and when a key bounce event is monitored, sending the virtual key value or the real key value of the target key to an electronic product, and releasing the current display window.
According to the key value triggering method provided by the second embodiment, on the basis of the first embodiment, whether the target key has the corresponding virtual key value function is judged, and whether the function value of the virtual key value function is empty is judged, so that whether the target key triggered by the user has the virtual key value is judged, the judging accuracy is improved effectively, and misoperation caused by misjudgment is avoided.
