Description
Technical Field
The present invention relates to a method for adjusting keyboard output signals, and more particularly, to a method for adjusting keyboard output signals according to a foreground application.
Background
With the increase of the computing speed of the computer, the user can execute more application programs in the same time period. In order to smoothly switch or operate among a plurality of applications, it is undoubtedly more convenient to switch or operate the applications using a keyboard rather than clicking a graphic on a screen using a mouse. Generally speaking, the keyboard comprises a typing key zone, a specific function zone, a number key zone and an editing key zone; among them, Function keys (F1 keys to F12 keys) located in a specific Function region have provided general functions such as renaming, searching, rearrangement, etc. printed on a Key cap to prompt. However, in order to meet the requirement of fast operation in an application program for different users, the users prefer to customize or expand the fast operation items represented by the function keys. There are also many kinds of software available in the market for the user to define the fast operation items of the function keys.
However, as the number of applications that a user executes simultaneously increases, such as text software, multimedia players, web browsers, games, etc.; the limited number of function keys limits the new functions that can be added, and further results in additional time for the user to set up, for example, considering the fast operation items to be set up for each function key, and even further, the user needs to remember which application programs correspond to which fast keys. Once a new application is installed, the user may be forced to modify the previously set script file for the application. Such repeated key setting and reloading of one of the set scripts will bring inconvenience and trouble to the user. Or, when the user needs to execute a certain application program, the user forgets the content of the shortcut key set at the beginning because a certain time is away from the last operation, and the advantage of changing the key function to provide quick start or input instruction cannot be embodied. On the whole, because the user has different setting requirements of the shortcut key for each application program, the shortage of the number of the rapid operation items which can be additionally arranged by the existing function key on the keyboard is more prominently displayed.
Disclosure of Invention
Accordingly, the present invention provides a method for dynamically adjusting keyboard output signals, thereby solving the above-mentioned inconveniences.
According to an embodiment of the present invention, a method for dynamically adjusting an output signal of a keyboard is adapted to a host electrically connected to the keyboard, the method comprising: detecting an application program currently running by a host, wherein the application program is in a foreground window; acquiring a function key configuration file corresponding to an application program, wherein the function key configuration file is a preset configuration file or a user-defined configuration file; intercepting a standard key code generated by pressing a function key, wherein the function key at least comprises keys F1 to F12; and outputting the user-defined key code combination to the host according to the standard key code and the function key configuration file.
According to an embodiment of the present invention, before detecting an application currently running on a host, a method for dynamically adjusting a keyboard output signal further includes: acquiring a hardware identification code of the keyboard, wherein the hardware identification code comprises a product identification code and a supplier identification code; and confirming whether the hardware identification code exists in the identification code list; and the detecting application further comprises: when the hardware identification code exists in the identification code list, the application program is detected. After confirming that the hardware identification code exists in the identification code list, the method further comprises the following steps: confirming a configuration file list corresponding to the hardware identification code; and determining whether a custom configuration file corresponding to the application program exists in the configuration file list; when the configuration file list has a user-defined configuration file corresponding to the application program, taking the user-defined configuration file as a function key configuration file; otherwise, using the preset configuration file in the configuration file list as the configuration file of the function key.
According to an embodiment of the present invention, the method for dynamically adjusting keyboard output signals further includes outputting a scan key before outputting the custom key combination. The user-defined combined key code is used for opening shortcuts, application programs or hyperlinks and outputting images, character strings, instructions, macros, single key signals or composite key signals. After obtaining a function key configuration file corresponding to the application program, the method further comprises: the names of the function keys and the user-defined key code combinations corresponding to the function keys are presented on a display device.
In summary, the method for dynamically adjusting keyboard output signals disclosed in the present invention achieves the following effects by running an embedded program that can be executed in a background in an operating system: the user can define the operation items of the function keys by himself, save a plurality of groups of self-defined function key configuration files, and automatically detect the current application program to provide the function key configuration file corresponding to the current application program. The user only needs to use the preset or self-defined function keys on the appointed keyboard at will through one-time setting and then the automatic detection and switching mechanism provided by the embedded program, and the operation items appointed to the function keys can be achieved by clicking the graphic on the screen.

Detailed Description
The detailed features and advantages of the present invention are described in detail in the embodiments below, which are sufficient for anyone skilled in the art to understand the technical contents of the present invention and to implement the present invention, and the related objects and advantages of the present invention can be easily understood by anyone skilled in the art according to the disclosure of the present specification, the protection scope of the claims and the attached drawings. The following examples further illustrate aspects of the present invention in detail, but are not intended to limit the scope of the invention in any way.
The method for dynamically adjusting the keyboard output signal described in the embodiment of the invention is realized by an embedded program running on a host and the host electrically connected to a specified keyboard. The embedded program is, for example, a Driver (Driver) already built in the computer or an application software that needs to be installed additionally, and the installation mode is, for example, installation through an optical disc and installation through a keyboard in a USB OTG (on-the-go) mode; downloading and installing from a website of an original factory; or downloaded and installed in the form of an app (application). After the embedded program is installed, the specified keyboard can be matched and the keyboard output signal can be dynamically adjusted according to the current application program. The following will describe each step in the method for dynamically adjusting keyboard output signals according to the present invention in detail.
Please refer to fig. 1, which is a flowchart illustrating a keyboard detection process according to an embodiment of the present invention. First, please refer to step S11, connect the keyboard and the host. In particular, the user connects the general keyboard or the designated keyboard to the computer in a wireless or wired manner. After the computer host is started, the embedded program can be started automatically or manually. The former is that the embedded program is started together with the loading of the operating system, and the latter is that the user presses a specific key on the keyboard (for example, a single key on the designated keyboard or a key combination formed by a plurality of keys on the general keyboard) or clicks by a mouse to start the embedded program. In addition, when the embedded program is executed, the user can change the embedded program to be not started (not executed) or further remove the installation (uninstallation) of the embedded program at any time.
Please refer to step S12, the hardware identification code of the keyboard is obtained. In detail, after the keyboard is connected to the host, the embedded program running in the operating system automatically detects the hardware identification code of the keyboard. The hardware identification code includes a Product identification code (PID) and a vendor identification code (VID).
Referring to step S13, the embedded program determines whether the hardware id is included in the built-in id list. In other words, the embedded program determines whether the currently connected keyboard model is supported. In practice, in addition to automatically checking the self-stored identification code list through the embedded program, the user can also select the keyboard type electrically connected to the host from the list. When the user later purchases a newly-pushed keyboard and connects to the host, the newly-pushed keyboard can be supported by updating the embedded program.
Please refer to step S14 and step S15. If it is determined in step S13 that the hardware id of the keyboard connected to the host is not in the id list built in the embedded program, the keyboard is regarded as a normal keyboard, and thus in step S14, a standard keyboard mode is entered, i.e., the embedded program is loaded into the configuration file of the standard keyboard on the market. Conversely, if the hardware identifier of the keyboard currently connected to the host is found from the identifier list in step S13, the keyboard is regarded as the designated keyboard, which supports the subsequent operation of the embedded program, and thus the user-defined keyboard mode is entered as shown in step S15.
Referring to step S21, the foreground application is detected. In detail, the foreground application is an application being operated by a user in an operating system running after the computer host is powered on, and the application is in a foreground window due to the operation of the user. The Operating System (OS) is, for example, Microsoft Windows or Apple MacOS, but the type of the operating System is not limited to the above. In addition, supplementary notes are: after the process from step S13 to step S15 is completed, that is, after the embedded program confirms that the hardware identifier of the keyboard currently connected to the host has the identifier list, the detection of the foreground application program can be started. This means that the embedded program will perform foreground application detection and subsequent steps only when the specified keyboard supported by the embedded program is connected to the host.
Referring to step S16, it is determined whether there is a custom configuration file in the configuration file list, and the custom configuration file corresponds to the application program detected in step S21. Specifically, in the flow from step S13 to step S15, the embedded program has confirmed that the hardware id of the keyboard exists in the id list. Then in step S21, the embedded program confirms what the foreground application is. Then, in step S16, the embedded program searches the configuration file list corresponding to the hardware identifier according to the detected application program. In practice, a plurality of configuration file lists can be stored in the embedded program, and different configuration file lists correspond to keyboards of different models. Each configuration file list comprises at least one configuration file, wherein one configuration file is a preset configuration file of an original factory, and the rest configuration files are self-defined configuration files. The custom configuration file is, for example, a configuration file set by a user through an embedded program. The preset configuration file is, for example, a configuration file preset (or updated) in the embedded program, or a configuration file downloaded by the user from the original factory website at a later date. It should be emphasized that each custom configuration file corresponds to an application running on the same computer host, and the default configuration file may correspond to an application as the custom configuration file or be common to all applications. The application programs include communication software such as Skype …, text software such as Word, Excel …, and multimedia playing software such as potlayer …, but the invention is not limited to the type of application programs.
Please refer to step S221 and step S222. If the embedded program determines in step S16 that the configuration file list only has a default configuration file and does not have any custom configuration file, the embedded program loads the default configuration file as the function key configuration file in step S221. Otherwise, as stated in step S222, the embedded program loads the custom configuration file as the function key configuration file.
The function key configuration file stores a plurality of function keys and operation items corresponding to the function keys. For example, the function key configuration file corresponding to Word application program has operation items such as "narrow and select words", "enlarge and select words", etc.; the function key configuration file corresponding to the multimedia playing application potlayer has functions of playing a previous song, pausing playing and the like. Therefore, when the embedded program detects that the foreground application is Word in step S21, and finds the self-defined configuration file corresponding to the application Word in the configuration file list in step S16, the function key configuration file loaded in step S21 includes the functions of "narrow-down selecting words" and "enlarge selecting words". Similarly, when the foreground application is Potplayer, the loaded function configuration file includes functions of "play previous song" and "pause playing".
Please refer to fig. 2, which is a flowchart illustrating adjusting keyboard output signals according to an embodiment of the present invention.
Referring to step S21, the foreground application is detected. This step is identical to step S21 of fig. 1, and will not be described herein again.
Please refer to step S22, a function key configuration file corresponding to the application program is obtained. This step corresponds to step S221 and step S222 in fig. 1. In short, the function key configuration file is a preset configuration file or a custom configuration file. When the configuration file list has a user-defined configuration file corresponding to the foreground application program, the embedded program takes the user-defined configuration file as a function key configuration file; otherwise, using the preset configuration file as the function key configuration file.
In another embodiment of the present invention, after the function key configuration file corresponding to the foreground application is obtained in step S22, the method may further include presenting the names of the function keys and the custom key code combinations corresponding to the function keys on a display device (e.g., a screen). Specifically, the embedded program can automatically display a status window (install panel) on the screen. The state window can also appear after a call signal is detected; the sending mode of the call signal is, for example, the user presses a separately provided start key, a designated key, or a combination key on the keyboard, which is not limited by the present invention. In the status window, each function key and the appointed operation item corresponding to each function key can be presented by characters, images (icon) or logos (logo) according to the currently loaded function key configuration file on the keyboard; the operation items include, but are not limited to, shortcuts, applications or hyperlinks, or output images, strings, commands, macros, single key signals or compound key signals. By means of the design of the state window, the effect of prompting the user can be achieved. In addition, the state window also allows the user to trigger the corresponding self-defined key code combination in a mode of clicking the function key image or the identification by a mouse. The user can further set or change the content of the function key configuration file through the status window. After the state window appears for more than a preset display time, or when the user sends the call signal again, the state window can disappear from the screen.
Please refer to step S23 and step S24, "wait for keyboard entry" and "determine whether the function key set in the function key profile is pressed". In detail, the embedded program waits for the user to input on the designated keyboard on the premise that the foreground window is not switched by the user. After detecting the input action, the embedded program checks whether the input action is from one of the function keys on the keyboard, as shown in step S24. The function keys include, but are not limited to, F1 key, F2 key, … key, and F12 key on the keyboard, and the user can also designate a certain key (e.g. Scroll Lock key, Numlock key, Space key …, etc., or F13 key additionally provided on a specific keyboard) or a combination of certain keys on the keyboard as a new function key in the custom configuration file. Therefore, in step S24, the embedded program obtains the function keys applicable to the current application according to the function key configuration file loaded in step S22, and detects whether the function keys are pressed.
Please refer to step S25, the standard key is obtained. Specifically, the embedded program intercepts the electronic signal sent from the designated keyboard to the host, which is a standard Key Code (Key Code) generated by the user pressing a function Key. For example, the standard key code of the F1 key is 112, the standard key code of the F2 key is 113, …, and the standard key code of the F12 key is 123.
Referring to step S26, the custom key combination is output. Specifically, the embedded program searches the standard key code intercepted in step S25 according to the function key configuration file corresponding to the current application program obtained in step S22, so as to obtain the custom key code combination set corresponding to the function key pressed by the user. The embedded program then sends this custom key combination back to the operating system. In practice, before outputting the custom key combination, a scan key is outputted. The Scan key Code, or Scan Code, is a data transmitted from most computer keyboards to computers to report which keys are pressed. For example, the scan key code of the IBM keyboard is "E0" represented by 16 carry. The custom key code combination is a control signal of the operation item corresponding to the function key pressed in step S24 in the function key configuration file corresponding to the foreground application. The operation items include, but are not limited to, opening shortcuts, applications or hyperlinks, outputting images, strings, commands, macros, single key signals or compound key signals, and the like.
Referring to step S27, it is determined whether to switch another application. In detail, after step S26 is completed, the embedded program checks whether the foreground window at this time has been switched by the user. If so, go back to step S21 to redetect what the application program currently in the foreground window is, and then execute the method for dynamically adjusting keyboard output signals according to the above-mentioned steps S21-S26. Conversely, if the user does not switch the currently operating application, the process returns to step S23, and the embedded program waits for the next keyboard input operation, and then executes the method for dynamically adjusting the keyboard output signal according to the process of steps S23 to S26.
Please refer to fig. 3 and 4, which are schematic diagrams of a status window and another status window according to the present invention. The status window 20 is presented on the display device 10 by the embedded program. In FIG. 3, the foreground application is Word and the background application is Potplayer, so the status window 20 presents a function key configuration file for Word. In FIG. 4, the foreground application is Potplayer and the background application is Word, so the status window 20 presents a function key configuration file for Potplayer.
Please continue to refer to fig. 3. The embedded program detects that the foreground application is Word in step S21, so the function key configuration file corresponding to Word is obtained in step S22, and the status window 20 is displayed on the display device 10 (e.g., screen) to indicate the function keys and the corresponding set operation items available to the user currently operating Word. The embedded program waits for an input action of the user on the keyboard at step S23. When the user presses the F1 key in step S24, the embedded program obtains the standard key code (112) of the F1 key in step S25, searches the function key configuration file with the standard key code, and outputs the custom key code combination in step S26 to achieve the function of reducing the selected characters. If it is determined in step S27 that the user has not switched away from Word, the user can reach the function of enlarging the selected Word by pressing the function key F2, or can reach the function of aligning the selected Word to the left by pressing the Scroll Lock key. Please refer to fig. 4 as mentioned above. If the user switches to potlayer in step S27, the user can reach the function of jumping back to the previous song when pressing the F1 key; when the F2 key is pressed, the function of playing the current song is achieved. As can be seen from the illustrative examples shown in fig. 3 and fig. 4, when the foreground applications are different, the user presses the same function key F1 to achieve different fast operation items, and the user can easily know all the currently available function keys and their corresponding operation items from the status window 20 (for example, in the potlayer application shown in fig. 4, there is no corresponding operation item for the F8 key to the F12 key, and there is no action for pressing the F8 key to the F12 key), so as to save the time that the user has to go through complicated operation steps to achieve the same function originally, and save the time that the user has to reload the function key configuration file when switching different applications.
In summary, the method for dynamically adjusting the keyboard output signal of the present invention can detect the keyboard currently connected to the host through the embedded program. When the model of the keyboard is confirmed to be supported, the function key configuration file corresponding to the model of the keyboard and the application program is loaded according to the application program which is operated by the current user and is located in the foreground, so that when the user presses the function key, a custom key code combination corresponding to the function key is generated, and the user can conveniently and quickly operate in the application program. The invention can automatically switch to the function key configuration files corresponding to the application programs according to different application programs, so that a user can set the operation items of the function keys preferred by the user for each application program without being limited by the number of the function keys. In addition, the invention also provides the design of the status window, which can prompt the user of the currently available function key and the corresponding quick operation item after a key call, and enable the user to click and execute the function key or change the content of the configuration file of the function key. The state window also updates the prompt as the application is switched. Generally speaking, the method for dynamically adjusting the keyboard output signal described in the invention can provide more diversified fast key self-defined operation according to different keyboard models on hardware and different application programs on software, thereby bringing more smooth operation experience to users.
Although the present invention has been described with reference to the above embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention.
