Description

A method and a system for controlling a hot key with combination function}

The present invention relates to a control system and in particular to a control system for a combined function hot key.

Computers have already become an indispensable means of modern business and daily life. Using the computer operating system as an example, earlier DOS systems lacked much interface between the computer and the user. Thus, for beginners, the barrier to initiation was very great. Then, after the Windows system came to the world, these barriers and difficulties were solved all at once. In general, the user works with the window system using a mouse. However, working with the Windows system as a normal program affects work efficiency. For example, in a window system, if you use the mouse to adjust some functions (such as speaker volume, screen brightness, etc.), you will need to open several windows to perform the adjustment.

SUMMARY OF THE INVENTION An object of the present invention is to provide a control method and a control system for a combined function hot key for solving the problems of the prior art mentioned above.

In order to achieve the above object, the control method according to the present invention is configured as follows. In accordance with another aspect of the present invention, a control method includes determining whether a hot key is clicked; Updating data in a data field when the hot key is clicked; Determining whether or not the first function key is clicked; If the first function key is clicked, outputting first keyboard coding based on data in the data field and the first function key; And executing a first service program based on the first keyboard coding.

The control system according to the present invention is constructed as follows. The control system according to the present invention includes a hot key and a first function key and outputs a hot key scanning signal when the hot key is clicked and outputs a first function key scanning signal when the first function key is clicked. keyboard; If the keyboard outputs the hot key scanning signal, the data of the data field is updated and if the keyboard outputs the first function key scanning signal after receiving the hot key scanning signal, the data of the data field and the first A control unit for outputting keyboard coding based on the function key scanning signal; And a terminal unit for sending an interrupt request when receiving the keyboard coding, wherein the operating system executes a service program based on the keyboard coding when the operating system learns the interrupt request.

The control method and control system according to the present invention described above provides the following effects. By using the control method and control system according to the present invention, users can work with windows without using a mouse, and various functions can be adjusted without having to open several windows, thereby greatly improving work efficiency.

In addition, since the control system according to the present invention can simultaneously click at least one hot key and at least one function key of the keyboard, the user can select a service program corresponding to the clicked hot key and the function key (for example, increase screen brightness / Reduction, etc.). Therefore, the work time can be greatly reduced.

Hereinafter, with reference to the accompanying drawings will be described the configuration and operation of the present invention.

1 is a view showing an embodiment of a control method according to the present invention. As shown in the figure, it is first determined whether or not a hot key is clicked (step S110). In this embodiment, the hot key is a key that does not happen when clicked alone. For example, Alt, Ctrl, Fn, Shift, etc.

In general, when a key of a keyboard is clicked, the keyboard outputs a corresponding scanning signal. In this embodiment, the controller receives a scanning signal of the keyboard and causes the controller to know which keyboard is clicked based on the scanning signal provided by the keyboard. In another embodiment, the controller may be a keyboard controller (KBC) or embedded controllers (EC).

If the hot key is clicked, the data of the data field is updated (step S120). In the present embodiment, when the controller receives a hot key scanning signal output from the keyboard, the controller immediately updates data in the data field. In a possible embodiment the initialization data of the data field is zero.

Next, it is determined whether or not the hot key is clicked again (step S130). If the hot key is clicked again, the data of the data field is updated again (step S120). In the present embodiment, the data of the data field indicates the order in which the hot key is clicked. In this embodiment, the order in which the hot key is clicked is not limited. The effect created when the order in which the hot key was clicked is different is also different. In other embodiments, step S130 may be omitted.

Next, it is determined whether the first function key is clicked (step S130). In this embodiment, the type of the first function key is not limited. In this embodiment, the function key is a key that can cause an event when clicked alone. For example, the function keys may be numeric keys, Jamo keys, or F1 to F12 keys. In another embodiment, the user may select click or release the hot key according to a habit. Therefore, the first function key may be clicked and the hot key may be kept clicked or the click may be released.

If the first function key is not clicked, step S130 is executed. When the first function key is clicked, the first keyboard coding is output based on the data of the data field and the first function key (step S150). In this embodiment, the controller (for example, KBC or EC) that receives the scanning signal output from the keyboard outputs the first keyboard coding only after both the hot key and the first function key are clicked. However, the controller does not output any keyboard coding when it receives only the scanning signal of the hot key, and outputs the first keyboard coding only after the function key is fully clicked (not just one function key).

In a possible embodiment, if the user wants to execute the first service program and at the same time the keys corresponding to the first service program are the hot key Fn and the function key F1, the controller may use the hot key Fn and the function key ( Only after all F1) are clicked, the keyboard coding corresponding to the first service program is output.

If the key corresponding to the first service program is a hot key (Fn) and a function key (1 and 2), the controller does not support keyboard coding until both the hot key (Fn) and the function key (1 and 2) are clicked. Outputs

Next, the first service program is executed based on the first keyboard coding (step S160). In the present embodiment, when the controller outputs the first keyboard coding, the terminal unit (for example, south bridge south bridge.) Executes the first service program based on the first keyboard coding. In a possible embodiment, the terminal unit issues an interrupt request for interrupting the program currently being executed. During the interruption period, the operating system (OS) executes the first service program. Only after the first service program is completed does the program interrupted immediately continue.

The present invention does not limit the type of interrupt request. In some possible embodiments, the interrupt request sent by the terminal unit may be a system control interrupt (SCI) or a system management interrupt (SMI) or interrupt request (IRQ).

2 is a view showing another embodiment of a control method according to the present invention. 2 has more steps S210 to S240 than those of FIG. 1. Steps S110 to S160 shown in Fig. 2 have not been described again because they have already been introduced above. In step S210, it is determined whether the reduction function is activated. When the reducing function is activated, the data of the data field of the hot key is reduced to the initial value (step S211). Then, step S110 is executed again.

And whether or not to operate the reduction function can be determined by the user itself. In a possible embodiment, the user may decide whether to operate the reduction function within the BIOS function option. If the reduction function is not activated, it is determined whether or not the second function key is clicked (step S220). The second function key may be a numeric key, a Jamo key, or may be a F1 to F12 key.

If the second function key is not clicked, step S210 is executed. When the second function key is clicked, the second keyboard coding is output based on the data of the data field and the second function key (step S230).

In this embodiment, since the reduction function has not yet been activated, the data of the data field is still preserved, and the controller outputs the second keyboard coding according to the data of the data field and the clicked second function key.

For example, if the reduction function is not activated, when the user clicks the hot key (Fn) and the function keys (F1 and F2), the controller can output two keyboard codings, one of the two keyboard codings. Corresponds to Fn + F1, and the other corresponds to Fn + F2. Based on the two keyboard codings, the operating system executes two service programs (e.g., adjust screen brightness or adjust speaker volume). Therefore, in this embodiment, the user can obtain the required effect even if the user does not click the hot key again.

When the reduction function is activated, when the user clicks the hot key Fn and the function keys F1 and F2, the controller outputs only one keyboard coding, where the keyboard coding corresponds to Fn + F1. Thus, the operating system runs only one service program. By clicking on function key F2 described earlier, the work system executes its own function of function key F2 (eg save, restore, etc.).

3A and 3B show that the controller of one embodiment according to the present invention has obtained keyboard coding. Referring to Fig. 3A, when the hot key Fn is clicked, the program moves to address 1. Next, when the function key F1 is clicked, it can be seen that the combination of the hot key Fn and the function key F1 corresponds to the keyboard coding keycode11. Similarly, if hot key Fn is clicked and then function key F2 is clicked, it can be seen that the combination of hot key Fn and function key F2 corresponds to keyboard coding keycode 12, and other combinations can also be deduced in this manner.

3B illustrates the relationship between the hot key Alt and the function key combination. If the hot key Alt is clicked, the program moves to address 2. Next, when the function key F2 is clicked, it can be seen that the combination of the hot key Alt and the function key F2 corresponds to the keyboard coding keycode22.

3C illustrates another embodiment in which the controller obtains keyboard coding. When hot key Fn and function key F1 are clicked in sequence, the program moves to address 0xA1. In this way, keyboard coding keycode 12 can be obtained. Similarly, when hot key Alt and function key F1 are clicked in sequence, the program moves to address 0xB1. This gives you the keyboard coding keycode 21.

As can be seen in Figures 3a to 3c, after both the hot key and the function key is clicked, the keyboard coding table is searched (as shown in Figure 3c) or when the hot key is clicked, the corresponding keyboard coding table is searched (Fig. 3a). And as shown in Figure 3b).

4 is an explanatory view of a control system according to the present invention. As shown, the control system 400 includes a keyboard 410, a control unit 420, a terminal unit 430, and an operating system 440. When the hot key is clicked, the keyboard 410 outputs a hot key scanning signal to the control unit 420. When the first function key is clicked, the keyboard 410 outputs the first function key scanning signal to the control unit 420.

The present invention does not limit the types of hot keys and function keys. In this embodiment, the hot key refers to a key that does not cause any action when clicked, and the function keys are vice versa. When a function key is clicked, it triggers an event (eg numbers, letters appear on the screen).

For example, the hot keys are keys Fn, Alt, Ctrl, Shift, etc. on the keyboard, and the function keys are numeric keys, letter keys, or F1-F12 keys. In addition, the present invention is not limited to the fact that the hot key must be released when the function key is clicked. The user may choose to keep the hot key click or release the click, depending on habit or convenience. Therefore, at the same time the function key is clicked, the hot key may be clicked or released.

In another embodiment, when the hot key is held in a clicked state, when the first function key is clicked, the keyboard 410 still outputs the first function key scanning signal. In another embodiment, when the first function key is clicked, the hot key is already clicked.

The control unit 420 may know the type of the clicked key according to the output signal of the keyboard 410. The control unit 420 is one keyboard controller (KBC) or embedded controllers (EC).

When the keyboard 410 outputs a hot key scanning signal, the control unit 420 updates data of a data field corresponding to the hot key scanning signal. The present invention does not limit the quantity of data fields. Different hot key scanning signals correspond to different data fields. In the present embodiment, the data of the data field represents the number of times hot keys corresponding to each other are clicked. In addition, the initial data of the data field may be 0 or other value.

After receiving the hot key scanning signal, when the keyboard 410 outputs the first function key scanning signal, the control unit 420 generates one keyboard coding keycode according to the data of the data field and the first function key scanning signal. Output The method by which the control unit 420 retrieves the keyboard coding keycode uses the method shown in Figs. 3A to 3C.

In addition, the keyboard 410 outputs a second function key scanning signal when the reverse function, the hot key and the first function key are not clicked, and then the second function key is clicked. The control unit 420 outputs the first and second keyboard codings (eg, keycode 11 and keycode 12) in accordance with the data of the data field and the first and second function key scanning signals.

On the contrary, when the reduction function is activated, if the second function key is clicked after the hot key and the first function key are clicked, the keyboard 410 outputs the second function key scanning signal. The control unit 420 then outputs a first keyboard coding (eg, keycode 11) based on the data of the data field and the first function key scanning signal. In the second function key scanning signal, the control unit 420 does not combine the hot key scanning signal with the second function key scanning signal.

When the control unit 430 receives the keyboard coding keycode, it immediately sends an interrupt request (for example, SCI or SMI) to interrupt the program currently being executed. During the interruption period, the operating system 440 executes the first service program based on the keyboard coding keycode (e.g., increasing / decreasing screen brightness or increasing / decreasing speaker volume). In the present embodiment, the terminal unit 430 includes a south bridge chip. A south bridge chip (not shown) sends an interrupt request SCI, SMI or IRQ.

Although preferred embodiments of the present invention have been described above, various modifications are possible to those skilled in the art without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined not only by the scope of the following claims, but also by the equivalents of the claims.
