Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an input system and an input method for distinguishing and processing key input events of a keyboard,

The present invention relates to an input system and an input method for classifying and processing a key input event of a keyboard, and more particularly, to a key input apparatus for inputting a key value for generating a key up event, And more particularly, to an input system and an input method for discriminating and processing key input events of a keyboard that can provide a method of effectively processing characters in accordance with a user's intention when they are mixed and provided with character input.

The operating system of a computer or a smart phone may be classified into a key-down operation, a key-up operation, a touch-down operation, (Such as touch-up operation), each event is processed according to a predefined procedure and method. When the input process is defined to occur, the event is operated as a physical key or a virtual key, respectively .

In the case of a conventional keyboard, which is often used in connection with a general desktop computer or integrated into a notebook computer, input processing is performed immediately when a key down event occurs.

On the other hand, mobile smart devices such as smart phones and tablet PCs use a virtual keyboard using a touch screen, and most of them wait for a touch up event rather than performing input processing at the time of a touch down event, As shown in FIG. The reason for doing this is that it is possible to reduce the misty rate by transmitting an input message to the touchup event rather than to perform input processing in the touchdown event, It is possible to make it possible to lower.

Generally, data or commands are input to a single desktop computer or a notebook computer by using one input means (a physical physical normal keyboard excluding the mouse). However, recently, a technique has been disclosed in which a virtual keyboard represented on a touch screen in addition to a general keyboard can be used as an auxiliary input means.

Input system " (hereinafter referred to as " input system ") for processing key input events of a keyboard means a general type of PC such as a desktop computer or a notebook computer, ).

The input device 200 includes a general keyboard 210 as a physical input means in a general sense, a smart phone 220, and a tablet PC 230. The smart phone 220 and the tablet PC 230 have a communication function, a touch screen input function, a program execution function, and the like, and are means for inputting data using a virtual keyboard displayed graphically on a touch screen screen Is used.

Typically, a desktop computer or a notebook computer receives a command using the general keyboard 210, and the general keyboard 210 used therein is the main input means. In the present invention, an auxiliary input means is additionally provided in addition to the main input means and is used in a system for inputting a command through a plurality of input means.

The input device 200 may be connected to the host computer 100 through a wired / wireless communication method to transmit data. In the case of wired communication, data is transmitted using an interface such as a serial port, PS / 2, or USB. In the case of wireless communication, an interface such as an RF signal, WIFI, and Bluetooth can be used.

The input system 110 receives the command input contents transmitted from the input device 200 and processes the received command or data according to the intention of the user so that the predetermined operation is executed.

The input system 110 is provided with a device connection unit 111, a key input reception unit 112, and an order processing unit 113. Such a configuration is generally implemented by software based on hardware.

The device connection unit 111 is connected to the first device 240 and the second device 250 in a wired / wireless communication manner and receives data or commands. The first device 240 and the second device 250 are devices used as means for inputting data or commands to the host computer 100. In the present invention, the first device 240, And the auxiliary input means is defined as the second device 250.

Data input from the first device 240 and the second device 250 are transmitted to the key input receiving unit 112 through the device connection unit 111. [ The key input receiving unit 112 receives data or commands according to a predetermined rule, and transmits the received data or commands to other components of the host computer 100. The key input receiving unit 112 recognizes data or a command according to the order inputted to the device connection unit 111 regardless of the intention of the user.

The order processing unit 113 arranges a plurality of continuously inputted data or commands in the correct order according to the input state of the input device 200. [ The user interprets the contents inputted through the input device 200 according to the user's intention and adjusts the order according to a predetermined rule and transfers the adjusted contents to the control unit (not shown) of the host computer 100. The control unit processes data or commands in the order set by the order processing unit 113.

A command input by the user by the user in the input device 200 is transmitted to the host computer 100. The key down and key-up are the criteria for determining the input time of the command. Keydown refers to data being input immediately when a user presses a button or a touch screen. This method is mainly used in a general physical general keyboard 210.

Key-up refers to data being input at a point when the user presses and releases a specific button or key. Most virtual keyboards use this method.

The first device 240 defined in the present invention is a key input device for performing a key input value when a key-up event or a key-down event occurs. The second device 250 is a key input device for performing a key input value Input device. The order processing unit 113 is located in the host computer 100, recognizes the event of each device, and coordinates the input process.

The host computer 100, the first device 240 and the second device 250 may exist in the following cases.

1) In a case where the first device 240 and the second device 250 are both devices separated from the host computer 100 (for example, in the case of a desktop computer connected to a virtual keyboard by wired / wireless connection of a physical keyboard)

2) There is a host computer 100 which is integrated with the first device 240 and the second device 250 is separated from the first device 240 and the first device 240 and the second device 250 are used together (For example, a smart device that provides a virtual keyboard using a touch screen to a notebook computer having a physical keyboard integrally)

3) There may be a host computer 100 integrated with both the first device 240 and the second device 250, but the present invention is not considered because it relates to a method of coordinating input from different devices. (For example, a notebook computer having a physical keyboard integrally and simultaneously activating a virtual keyboard by using a touch screen provided)

Example 1

The first device 240 is a physical general keyboard 210 that performs input processing when a key down event occurs. The second device 250 is a virtual keyboard using a touch screen, and is a device for input processing when a key up event is generated.

Fig. 3 shows an input order processing method in such a case.

The order processing unit 113 directly recognizes the occurrence of an up-down event of a specific key by directly communicating with the input device 200 or by directly hooking the host computer 100 to the input device 200 via the host computer 100 100) can indirectly recognize the occurrence of the up-down event of the specific key. If both of the two methods are possible, the order processing unit 113 defines a point at which the sequence processing unit 113 recognizes the event more quickly.

In practice, it is common for the order processing unit 113 to be an indirect method in order to recognize the occurrence of the up-down event of the general keyboard 210. This is because the general keyboard is considered to be a separate device rather than considering the order processing unit 113. In addition, it is determined that the direct processing method is general in order for the order processing unit 113 to recognize the occurrence of the up-down event of the virtual keyboard, but the present invention is not limited thereto. This is because it is generally seen that, in the software implementation of the virtual keyboard, the software implementation of the order processing unit 113 is performed together with the implementation of the device connection unit 111 to be located in the host computer 100.

The order processing unit 113 recognizes that the specific virtual key of the second device 250 is touch-down. The order processing unit 113 is located in the host computer 100 and can recognize that a specific virtual key of the second device 250 is touch-down as information transmitted through an internal circuit or a communication network. When it is determined that the key down of the specific key of the first device 240 has occurred, it is determined that the touch up event of the corresponding key has not yet been generated in the second device 250, The key input value of the touchdown of the second device 250 is input first.

A method for inputting a new key input value is to generate a new input message with the corresponding key input value touched down during the key down event processing of the first device 240, thereby processing the input message first. In some cases, you can directly manipulate the string to be entered into the focused control.

Thereafter, the input is made to the key-down key input value of the first device 240. There may be a method in which the input process is continued and completed because the key down event of the key has already been generated, or a method of directly manipulating the string to be input to the focused control. Subsequently, even if the touch-up of the corresponding key occurs, processing is performed so that the input processing is not started again because the key input value has already been processed.

In the virtual keyboard of the second device 250, even if the finger does not fall off from the 'A' yet (i.e., the touch-up has not occurred) When the user presses 'a' on the keypad 210 (key down), the order processor processes 'a' first and displays 'a', and displays 'a' corresponding to the user's intention.

Example 2

Meanwhile, the order processing unit 113 may adjust a situation in which the second device 250 generates a plurality of events.

If the second device 250 sequentially recognizes from the first touchdown to the Nth touchdown in a state in which there is no touch-up for any key, in the case of existing virtual keyboards, The first touchdown key input is first processed and displayed at the time of occurrence. However, in the present invention, it is assumed that the first to Nth key down events until the Nth touchdown are processed first and are not displayed. If the key input value of the first touchdown is already processed and displayed at the time of the second touchdown, the second touchdown key that has not yet been input and displayed and the first touchdown key 240 (Single Switching) between the key-down key in the first embodiment and can be processed in the same manner as in the previous embodiment.

When the first device 240 recognizes that a key down has occurred, the order processing unit 113 can recognize that a key down of a specific key has occurred through hooking (data interception) in the host computer 100 .

The key input value (s) touched down by the second device 250 may be input before the touchup event is generated in the second device 250 or before the order processing unit 113 recognizes the touchup event It does. The first method is to generate a new input message (s) with the corresponding key input value (s) touched down during the key down event processing of the intercepted first device 240 so that the input message It does. There is also a way to manipulate the string to be entered in the focused control directly.

And thereafter input can be made to the key-down key input value of the first device 240. There is a method of causing a key down event of the key to be processed and being in the process of being processed so that the input process is continued and completed or a method of directly manipulating a character string to be input to the focused control.

Even if touch-up of the first to the N-th keys occurs, since the corresponding key input values have already been input, the input processing is not started again.

If you enter 'circle', the initial state 'heh' is entered first and assumed to be the default state. In this case, if 'ㅗ' is pressed (first touchdown) in the virtual keyboard of the second device 250, and 'a' is pressed again in the pressed state (second touchdown) (Or key down) on the general keyboard 210 of the first device 240, the order processing unit 113 first processes and displays the 'ㅘ' input, The input 'c' is processed as follows to finally input 'circle' that matches the user's intention.

Example 3

On the other hand, the order processing unit 113 recognizes that the touchdown has occurred sequentially without any touch-up from the first touchdown to the (N-1) touchdown in the second device 250, If it is recognized that the first key down has occurred in the first device 240 immediately before the N touchdown is recognized, a switching state occurs and the first to (N-1) th touch down key input values and the first key An error situation occurs in which the N-th touchdown is input after the process of switching the down key input value is performed.

Since the first key down occurs without any touch-up with respect to the first through N-th touchdown keys, the user intends to input the key input values of the first through N-th touchdown It is reasonable to see that the key input value of the first key down is inputted and the error processing is performed accordingly.

Since the above-described single switching or multiple switching has already been performed, the key input value already keyed down is inputted. 1) Delete the keyed-down keystroke value first (the way to erase the keystroke is to generate a message to input the backspace, or directly manipulate the string to be input to the focused control) 2) (Input method is to generate an input message by corresponding key input value, or to directly manipulate a string to be input to the focused control, etc.) 3) Next, the key input value is input again.

In case of inputting 'circle', it is assumed that the initial state in which the prefix 'ㅎ' is displayed first. At this time, the order processing unit 113 recognizes that the 'ㅗ' is pressed on the virtual keyboard of the second device 250 (first touchdown), and in this state, 'a' When recognizing that the 'c' is pressed first on the general keyboard 210 of the first device 240 (the first key down) before recognizing the depressed state, the sequence processing unit 113 recognizes the switching situation, ㅗ 'and' ㄴ '(in this case' horn ').

The process (second touchdown) for pressing 'a' is a subordinate, resulting in 'hana', which causes a different error situation from the user's intention.

In this case, before inputting 'a', input backspace first to delete 1) key-down value 'b', 2) input second touchdown 'a' ) If you enter 'ㄴ', which is the key input value of the key down again, the error will be corrected and displayed as intended.

On the other hand, if the second processing unit 113 recognizes the second key down generated again by the first device 240 in the middle of the switching error process, another error occurs. need. In the midst of switching error processing, there are two methods: (1) first erase the key input value of the first key down, (the method of erasing the backspace or directly manipulating the string to be input to the focused control) (2) Nth touchdown key input value is input, (input method is to generate input message by corresponding key input value and to process it, and (1) Backspace, (2) Nth touchdown key input value, and (3) First key down key input value are sequentially As shown in FIG.

The input processing of (1) to (3) is sequentially applied in sequence to correct an error generated. Therefore, even if the second key down is recognized in the middle of the processing , The user intends to input the key input value of the second key down after performing the sequential input process of the corresponding ① through ③, And make error handling accordingly.

When the second key-down is recognized in the sequential input process, the unprocessed input is processed ahead of the key-input value of the second key-down (the first input process is the second key- There is a way to cause the input message (s) to be processed first by generating a new input message (s) with the unprocessed key input value (s) during the key down event processing, A method of directly manipulating a string, etc. Thereafter, the key input value of the second key-down is inputted.

However, the unprocessed inputs are in the state that the input is yet to be processed at the time when the second key down is recognized, and since the input processing is already started and processed, the input is processed in parallel in a separate thread at any time during the preceding input processing Can happen. Therefore, the key input value is input processed twice. In order to avoid the result that the input is displayed twice, it is necessary to first copy the unprocessed key input values into a memory space that each thread can access in common, If this occurs, the duplicate value is deleted or a flag is set. In such a case, the second thread of the same key input value is invalidated by the other thread, thereby avoiding duplicate processing.

Example 4

The final embodiment is a case where the first device 240 and the second device 250 are virtual keyboards in which data is input when a key-up event occurs, as shown in FIG.

Since both the first device 240 and the second device 250 use a virtual keyboard, data is input when a key-up event occurs.

The key down event of the second device 250 occurs in a state where the input is recognized in the first device 240, as in the above-described method. Further, an additional key down event of the first device 240 occurs before the key up event of the second device 250 occurs. The order processing unit 113 may input the key input value of the second device 250 even before the key up event of the second device 250 occurs when the second key down event of the first device 240 occurs, do.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, As will be understood by those skilled in the art. Therefore, it should be understood that the above-described embodiments are to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than the foregoing description, It is intended that all changes and modifications derived from the equivalent concept be included within the scope of the present invention.
