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 foreground application programs.
Background
With the increase of the computing speed of the computer, users can execute more application programs in the same time period. In order to smoothly switch or operate between a plurality of applications, it is undoubtedly more convenient to switch or operate the applications using a keyboard than to click an icon 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, the Function keys (Function keys, F1 keys to F12 keys) located in a specific Function area have provided general functions such as renaming, searching, rearrangement, etc. printed on the Key cap for prompting.
However, since the number of the existing function keys on the keyboard is limited and a single key can only perform a single function, in practical applications, a user often has to continuously use a plurality of function keys to complete a series of operations. As the number of applications that a user executes simultaneously increases, such as document software, drawing software, web browsers, games, etc.; the limited number of function keys limits the new functions that can be added, which in turn results in additional time for the user to set choices, for example, regarding quick operation items to be set for each function key. 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.

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.
In summary, the present invention is intended to solve the problem that the limited function keys on the keyboard result in too few fast operation items that can be customized by the user, and distinguish from the perspective of the application program, so that the user can select one or more keys on the keyboard and set the key configuration file, thereby achieving the goal of implementing customized complex operation items based on simple key operation. The following describes each step in the method for dynamically adjusting keyboard output signals according to the present invention in detail.
The method for dynamically adjusting the keyboard output signal described in an embodiment of the present invention is implemented by an embedded program running on a host and a computer host connected to a designated keyboard. The embedded program is, for example, a Driver (Driver) built in the computer; or by optical disc mounting; or installed in the manner of universal serial bus USB OTG (on-the-go) through the keyboard; or the user downloads the data from the website of the original factory; or an application software downloaded and installed in the form of an application program app (application). After the embedded program is installed, the keyboard output signal can be dynamically adjusted according to the current application program by matching with the appointed keyboard.
Referring to fig. 1, a flowchart of detecting a keyboard according to an embodiment of the invention is shown. First, please refer to step S11, connect the keyboard and the host. In particular, in practice, after the computer is turned on, the user needs to electrically connect the keyboard to the computer in a wireless or wired manner. The present invention is not limited to the number of keys on the keyboard, but it should be noted that the method for dynamically adjusting the output signal of the keyboard described in an embodiment of the present invention is applicable to all keys on the connected specified keyboard, so that a user can select a key combination formed by one or more keys on the keyboard to set the key configuration file. The embedded program can be started together with the loading of the operating system in principle or started in a mode of clicking by a user. 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. Specifically, after detecting that the keyboard is connected to the host, the hardware identification code of the keyboard is automatically detected through an embedded program which is already running in an operating system. The hardware identification code comprises a Product identification code (Product ID, PID) and a supplier identification code (vendor ID, 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 checks whether the current keyboard is included in the keyboard model supported by itself. 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. Later when the user additionally purchases a newly launched keyboard and connects to the host, the newly launched keyboard may 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 loads a configuration file of a standard normal keyboard sold in the market. Conversely, if it is determined in step S13 that the identifier list includes the hardware identifier of the keyboard connected to the host, it indicates that the keyboard supports the subsequent operation of the embedded program, and thus, in step S15, the user-defined keyboard mode is entered and the mode signal is obtained.
Referring to step S151, it is determined whether the mode signal obtained in step S15 is a general signal. The mode signal, for example, a state window presented on the screen by the user is clicked, and the embedded program sends out a corresponding mode signal according to the mode selected by the user. For example, the mode signal may be used to indicate two modes: a general mode and a custom mode. When the mode signal indicates the general mode, the embedded program loads the general configuration file as shown in step S152. Basically, this common configuration file applies to all applications. On the other hand, when the mode signal is designated as the custom mode, the embedded program loads the custom configuration file corresponding to the application program according to the application program currently executed by the host computer, as described in detail below.
Referring to step S21, a foreground application is detected. In detail, the foreground application is an application being operated by a user in an operating system running after the host computer is turned on, and the application is in a foreground window (formed window) due to the user operation. The Operating System (OS) may be, for example, Microsoft Windows or Apple Mac OS, but the type of the operating System is not limited thereto. 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 embedded program can start to obtain the mode signal, and when the mode signal indicates the custom mode, the foreground application is detected. This means that the embedded program will perform foreground application detection and its subsequent steps only when the specified keyboard supported by the embedded program is connected to the host and the user decides to select the custom mode.
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. Next, in step S21, the embedded program confirms why 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 host computer, 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 …, document 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 the Word of the document application program has operation items such as "narrow selected words" and "enlarge selected words"; 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 select Word" and "enlarge select Word". 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 the keyboard output signal according to an embodiment of the invention.
Referring to step S21, a 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.
Please refer to step S23 and step S24, "wait for keyboard input" and "determine whether the key or key combination set in the key configuration file is pressed". In detail, the embedded program waits for the input action of the user 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 the action result of one or more key combinations on the keyboard, as shown in step S24. Since the user can self-designate a certain key or a certain combination of keys on the keyboard as a new shortcut key in the custom configuration file. Therefore, in step S24, the embedded program obtains the keys with the customized function suitable for the current application according to the key configuration file loaded in step S22, and detects whether the keys with the customized function are pressed.
Please refer to step S25, the standard key is obtained. Specifically, the embedded program intercepts the electronic signals sent from the designated keyboard to the host, where the electronic signals are one or more standard Key codes (Key codes) generated by a user pressing a Key combination formed by a Key or keys on the keyboard. For example, the standard key code for Ctrl key is 7, the standard key code for Tab key is 9, …, and the standard key code for a key is 65. Alternatively, at least one of the same keys is repeatedly pressed within a short predetermined time (e.g., pressing the a key 3 times within 0.5 second) may be regarded as a key combination.
Referring to step S26, the custom key combination or the universal key combination is output. Specifically, the key code combinations are distinguished depending on the mode selected by the user at step S15. Specifically, if the user selects the universal mode in step S151, in step S26, the embedded program searches the universal configuration file according to the at least one standard key intercepted in step S25 to obtain the universal key combination corresponding to the key pressed by the user. On the other hand, if the mode signal indicates the user-defined mode in step S151, the embedded program searches the at least one standard key code intercepted in step S25 according to the key configuration file corresponding to the current application program obtained in step S22, so as to obtain the user-defined key code combination corresponding to the key pressed by the user. The embedded program then sends this generic or custom key code combination back to the operating system. It must be specifically noted that the universal key code combination is applicable to all applications. In other words, in the universal mode, the user will correspondingly send out the same universal key code combination for the same key pressed by a plurality of different applications. In contrast, the custom key code combinations are adapted to different applications, and the pre-configured custom key code combinations in each application are output. In practice, before outputting the general or custom key combination, a scan key is output. The scan key code, also known as the keyboard scan code (ScanCode), is a data item transmitted by most computer keyboards to the computer to report which keys are pressed. For example, the scan key code of the IBM keyboard is "E0" represented by 16 carry. The user-defined key code combination is the control signal of the operation item corresponding to the key pressed in step S24 in the key configuration file corresponding to the foreground application. The operation items include, but are not limited to, opening shortcuts, applications or hyperlinks, outputting images, character strings, instructions, macros, single key signals or composite key signals, and the like.
In practice, when executing an application, a user may press a key combination formed by a single key or multiple keys set in a key configuration file corresponding to the application, so as to achieve operation items that may be achieved by complicated steps, such as opening a file menu, selecting a recently opened file list, and formatting a selected item. In addition, different functions can be set for the same single key or a plurality of key combinations according to different application programs. For example, pressing the F1 key and the N key simultaneously in the application Word counts the number of words in the file, while pressing the same key combination simultaneously in the application Potplayer randomly plays all music files in the designated folder.
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 is currently in the foreground window, 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 S22 to S26.
Therefore, by the method for dynamically adjusting keyboard output signals introduced in steps S21-S27, the user can save the time that he or she must go through complicated operation steps to achieve the same function, and also save the time that he or she must reload the key configuration file by himself or herself 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 supported and the user selects the user-defined mode, the 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 positioned on the foreground, so that the user-defined key code combination corresponding to the key can be generated when the user presses the key with the user-defined function, and the user can conveniently and quickly operate in the application program. The method and the device can adapt to different application programs to automatically switch to the key configuration files corresponding to the application programs, so that a user does not need to be limited by the number of only preset function keys on a keyboard, and can set the preferred shortcut key operation items for each application program. In addition to the custom mode described above, the present invention also provides a common mode and corresponding common configuration file for all applications. Generally speaking, the method for dynamically adjusting the keyboard output signal described in the present invention can allow the user to select a single key or a key combination formed by multiple keys on the keyboard to set the key configuration file according to the difference of the keyboard models in hardware and the difference of the application programs in software, thereby providing more diversified shortcut key self-defined operation and bringing more smooth operation experience to the user.
The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it should be understood that various changes and modifications can be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
