8 is a diagram illustrating attributes of an input key.

Referring to FIG. 8, an input key installed in a hand manipulation input device or a foot manipulation input device, for example, a keyboard, may be divided into a non-character key and a letter key. The non-character key may be divided into a case-sensitive input or an expansion key for extending the input range of the input key and a TOGGLE key for changing the state of the input device. In general-purpose keyboards used in personal computers, the non-character key includes the enter key, the backspace key, the function key, the escape key, the insert key, and the deli ( DELETE key, HOME key, END key, PAGE UP, PAGE DOWN, directional key or other keyboard specific function keys. Character keys are composed of A to Z, 0 to 9, and the like.

A typical keyboard consists of non-character keys and letter keys. The non-character key is further divided into an extension key composed of a control key, a shift key, and an alt key, and a state transition key composed of a caps lock key, a number lock key, and a Korean / English key. Extended keys are used to enter shortcut keys, uppercase and lowercase letters, and control commands along with character keys. When an extended key is entered, (1) two characters are concatenated using the BACKSPACE control character (ISO / IEC 646), or (2) the two characters are concatenated with a non-blank character before the concatenated character. spacing) to indicate a connection character (ISO / IEC 6937). The general key scan algorithm waits until a character key is input when an extension key is input, and connects an extension key and a key scan code by the character key when a character key is input.

The state change key is used to change the input state of the keyboard, that is, a case input or Korean / English input state. Therefore, unlike the extended key, there is no need to enter additional character keys.

An AT keyboard, which is a typical hand manipulation input device, will be described with reference to the property of an input key.

The keyboard has a plurality of input keys, and a unique identifier (hereinafter referred to as a key scan code) is assigned to each input key. When the user enters a through the keyboard, the data actually generated on the keyboard is not the letter a but the key scan code pre-assigned to the input key named a. The keyboard before the AT keyboard typically generates a key scan code of 1 byte and transmits it to the computer body, and the keyboard after the AT keyboard typically generates a 2 byte key scan code and transmits it to the computer body. The key scan code transmitted to the computer main body is converted into a character code that can be processed in a computer such as an ASCII code by a key scan code processing routine, and used.

When the keyboard receives a key input from the user, the keyboard generates an interrupt to the computer main body, notifying the user of the key input, and then transmitting a key scan code. The user's keystroke is divided into the key press start and the key press end. In the present specification, the key input or the input key operation includes both the key press start and the key press end described above. The keyboard generates a key scan code whenever a user starts pressing a key or ends a key press.The key scan code generated at the start of a key press is called a make code, and the key scan code generated at the end of a key press is generated. It is called a brake code.

In the case of character input, when a user presses any input key, the keyboard generates a make code and transmits it to the computer body, and when the user releases the keyboard, the keyboard generates a break code and transmits it to the computer body.

In the case of inputting a character key together with an extension key, the processing method includes (1) each time a corresponding key scan code is generated and transmitted to the computer main body, and the key scan code processing routine causes the extension key and the key. Synthesizing the character keys (hereinafter referred to as the processing method after sending the key scan code), or (2) When an extension key is input, wait for the input of the character key, and then transmit the key scan code combining the extension key and the character key to the computer ( In the following description, it is referred to as a transmission method after processing a key scan code. According to the processing method after the key scan code is transmitted, the keyboard only plays a role of generating only a key scan code for all key inputs, and it is determined by a key scan processing routine located in the computer main body whether or not a key is input using an extended key. . Therefore, the processing burden of the keyboard is reduced, but the processing burden of the computer main body is increased, so that the processing method after the key scan code transmission is an undesirable key input processing method. According to the transmission method after processing the key scan code, AT keyboard is generally composed of 101 ~ 108 input keys and generates 2 byte key scan code. Processing burden is reduced. Therefore, in the present specification, a transmission scheme after key scan code processing will be described as an example. However, this does not limit the scope of the present invention to the case of the transmission method after the key scan code processing, and a person having ordinary knowledge in the field to which the present invention pertains is based on the transmission method after the key scan code processing described below. It is apparent that a key input processing method corresponding to a processing method after transmission of a key scan code can be easily implemented.

The key scan code processing routine of the computer main body generates an interrupt to the central processing unit inside the computer to indicate that there is a key input, and converts the key scan code transmitted from the keyboard into a predetermined character code. The converted character code is sent to the location designated by the central processing unit. In the case of the key scan code post-transmission processing method, the key scan code processing routine determines whether (a) the expansion key and the character key are pressed together, (b) whether the state conversion key is pressed, (c) It is determined whether it is a reboot command such as a special combination of expansion key and character key, for example, control key + alt key + delete key. .

Hereinafter, a configuration of a foot manipulation input device and a method of processing input data will be described in detail with reference to the accompanying drawings.

9 is an exemplary diagram illustrating a combination of a conventional keyboard, a foot manipulation input device and a computer according to an exemplary embodiment of the present invention, and FIG. 10A is a diagram illustrating a case in which a foot manipulation input device and a computer are wirelessly connected. 10B is a block diagram showing the format of a wireless key scan code, FIG. 10C is a block diagram showing the format of another wireless key scan code, and FIG. 10D is a block showing the format of another wireless key scan code. It is also. The hand manipulation input device, the foot manipulation input device and the computer are connected as shown in Figs. 9 and 10A.

Referring to FIG. 9, the foot manipulation input device 100 is coupled between a conventional hand manipulation input device 150 and a computer 160. That is, the data input by the user using the hand manipulation input apparatus 150 is converted into a key scan code by the hand manipulation input apparatus 150 according to the input order, and then the computer 160 is performed through the foot manipulation input apparatus 100. Is entered. In addition, when the user inputs the hand manipulation input device 150 and the foot manipulation input device 100 simultaneously, the key scan code output from the hand manipulation input device 150 is input by the foot manipulation input device 100. It is input to the computer 160 in combination with a key scan code corresponding to the received key. That is, when the user inputs s of the hand manipulation input apparatus 150 while pressing the shift key of the foot manipulation input apparatus 100, the foot manipulation input apparatus 100 is displayed by the user at the hand manipulation input apparatus 150. The same key scan code as that of the shift key + s key ”is generated and input to the computer 100.

The foot manipulation input device 100 and the computer 160 may be connected by a serial communication cable, but are preferably connected by a universal serial bus (USB). In particular, when the foot manipulation input apparatus 100 further includes a position display apparatus, when the foot manipulation input apparatus 100 is connected to the computer 160 using a serial communication cable, the position display apparatus must be used only by using a separate connection means. The location data output by the user may be input to the computer 160.

Referring to FIG. 10A, the foot manipulation input device 101 may wirelessly transmit data input by a user to the computer 161. Infrared communication (IrDA) may be generally used as a wireless communication method used in a computer peripheral period, and the radio frequency is considered that the foot manipulation input device 101 may not be located on the same plane as the computer 161. Radio frequency (RF) communication may be used.

When the foot manipulation input device 101 is wirelessly connected to the computer 161, the foot manipulation input device 101 is a key scan code different from a key scan code transmitted when the wire manipulation input device 101 is connected by wire (hereinafter, referred to as a wireless key scan code). Transmits). The format of the wireless key scan code is shown in FIGS. 10B-10D.

10B to 10D, the wireless key scan code includes a keyboard identifier 101a, 103a, 105a, key scan codes 101b, 103c, 105d, channel information 101c, 103d, 105e and an error checksum 101d, 103e, 105f).

The keyboard identifiers 101a, 103a, and 105a are unique identifiers that enable the computer 161 to identify the foot manipulation input device 101. When a wireless input device such as a wireless mouse is used in addition to the foot manipulation input device 101, The computer 161 serves as a reference for determining which device the input is from. The number of bits allocated to the keyboard identifiers 101a, 103a, and 105a may vary according to a wireless communication method, and may also vary according to an operating system installed in a computer.

The key scan codes 101b, 103c, and 105d are key scan codes generated by the foot manipulation input device 101 or the hand manipulation input device 151, and are keys generated in the case of a wired connection as shown in FIG. Same as the scan code.

The channel information 101c, 103d, 105e includes information about a channel used in wireless communication between the foot manipulation input device 101 and the computer 161.

The error checksums 101d, 103e, and 105f contain information for correcting an error that occurs when transmitting and receiving a wireless key scan code.

Referring to FIG. 10C, the wireless key scan code may further include a make code / break code flag 103b. The make code / break code flag 103b indicates whether the wireless key scan code is a make code or a break code.

Referring to FIG. 10D, the wireless key scan code may further include a make code / break code flag 103b and a non-magnetic key code 105c. Since the make code / break code flag 103b has been described above, only the non-magnetic key code 105c will be described. The non-key key code 105c indicates whether the key scan code included in the wireless key scan code is a key scan code generated by being input with a non-key key among a non-key key, a shift key, an alt key, or a control key.

The non-magnetic key code 105c may have an error correction function that occurs when transmitting and receiving a wireless key scan code that is different from the error correction functions of the error checksums 101d, 103e, and 105f. According to the processing method after the key scan code is transmitted, a key scan code corresponding to the extended key and a key scan code corresponding to the character key are separately transmitted. Therefore, if the wireless key scan code corresponding to the extended key is lost, the computer that receives the wireless key scan code corresponding to the character key to be input later cannot check whether the extended key is input. To prevent this, by transmitting information on the extension key to the wireless key scan code corresponding to the character key input together with the extension key, whether the extension key is input even if the wireless key scan code for the extension key entered together is lost. Allow the computer to check.

11 is a block diagram showing the configuration of a foot operation input device according to an embodiment of the present invention.

Referring to FIG. 11, the foot manipulation input device may include a keyboard matrix 107, a scan code generator 109, a central processor 113, a first transceiver 117, a second transceiver 121, and a memory 123. ). In addition, the foot manipulation input apparatus may further include a touch pad controller 109. Each component is connected as shown in the figure, and the buffer, clock generator and power supply are omitted.

The keyboard matrix 107 includes a plurality of input keys, and generates key scan data when a key input is received from a user. The key scan data is a unique identifier assigned to each input key and is a reference signal that can determine which key is pressed.

The keyboard matrix 107 is provided with at least one input key on the upper left / right side of the foot manipulation input device so that the input manipulation by each of the left and right feet of the user is possible. In another embodiment, at least one input key may be provided to allow a user to perform an input operation by one foot.

The scan code generation unit 109 generates a key scan code based on the key scan data of the keyboard matrix 107. When the scan code generation unit 109 receives the key scan data, the scan code generation unit 109 generates a key scan code basically assigned to each of the plurality of input keys included in the keyboard matrix 107. For example, in the case of a foot operation input device having three input keys on the left and right sides, the left and right input key 1 is a shift key and the left and right input key 2 is a hand. The control keys of the manipulation input device and the left / right input keys 3 may be basically assigned to the Korean / English switching keys. The key scan code generated by the scan code generation unit 109 is a general-purpose key scan code that can be directly converted into a character code on a computer, and is the same key as the key scan code generated when the same key is pressed on a hand manipulation input device. It is preferably a scan code.

The first transceiver 117 receives the key scan code from the hand manipulation input device. The first transceiver 117 that receives the key scan code from the hand manipulation input device generates an interrupt to notify the central processing unit 113 that the key scan code has been input from the hand manipulation input device. The first transceiver 117 includes a communication port capable of receiving a key scan code from a hand manipulation input device. The communication port may be either a universal serial bus port, a PS / 2 port, or a serial communication port, depending on the type of the hand manipulation input device. In another embodiment, the first transceiver 117 may include a universal serial bus port, a PS / 2 port, and a serial port and a port selector. The port selector detects a port to which the hand manipulation input device is connected, and transmits a key scan code input to the corresponding port to the central processing unit 113.

When the hand manipulation input device is a wireless keyboard, the first transceiver 117 may be a wireless transceiver that may wirelessly receive a key scan code from the hand manipulation input device. In general, wireless keyboards are designed to send key scan codes directly to an electronic information processing device. Therefore, when the hand manipulation input device is a wireless keyboard, it is desirable to change the input device setting of the electronic information processing device or to install a separate program so that only the foot manipulation input device receives the key scan code transmitted from the wireless keyboard. Do.

The central processing unit 113 processes the key scan code input from the hand manipulation input device and the key scan code input from the scan code generating unit 109 to synthesize the key scan code to be input to the computer. That is, the central processing unit 113 scans a key generated by a key input by a key input using only a hand manipulation input device by a key scan code generated by a user input using both a hand manipulation input device and a foot manipulation input device at the same time. Synthesize the keys input by both input devices to be identical to the code. The synthesized key scan code is transmitted to the computer through the second transceiver 121.

The central processing unit 113 operates differently according to the basic mode and the allocation mode. The basic mode is a mode for synthesizing a key scan code to be transmitted to a computer by using a key scan code corresponding to a key value uniquely assigned to an input key of a foot manipulation input device. The assignment mode is a mode for synthesizing a key scan code to be transmitted to a computer by using a key scan code corresponding to a new key assigned to an input key of a foot manipulation input device. In order to use the foot manipulation input device in the assignment mode, the user can assign a new key (hereinafter referred to as the reassignment key) to each input key of the foot manipulation input device through the user input screen. The reassignment key is transmitted to the foot manipulation input device through the second transceiver 121, and the central processing unit 113 stores the key in the key assignment table of the memory 123. The central processing unit 113 refers to the key assignment table stored in the memory 123 whenever there is a key input by the foot manipulation input device, and corresponds to the reassigned key corresponding to the key scan code output from the scan code generation unit 109. Change to the key scan code. The changed key scan code and the key scan code input from the hand manipulation input device are synthesized in the central processing unit 113 and transmitted to the computer.

In another embodiment, each input key is based on one key, and may also reassign a composite key combining two or more keys. That is, in order to produce the same effect as pressing the control key and the shift key at the same time, the control key and the shift key may be reassigned to one input key.

In another embodiment, an operation key included in a position display device (eg, a mouse) not installed in the foot operation input device may be assigned to the input key. For example, when using a web browsing program such as Internet Explorer, right-clicking a mouse displays a pop-up menu containing simple operation commands on the screen. The user selects the menu again and clicks the left mouse button to move to the previous web page or the next web page, and then clicks an operation command on the menu or inputs a letter key (such as B or O in Internet Explorer). To simplify this series of input operations, you can assign compound keys to input keys, such as right-clicking the mouse (right mouse key) + selecting the previous web page navigation command and then left-clicking the mouse (left key or character key). have. To this end, a separate processing program should be installed in the electronic information processing apparatus so that the operation key signal of the position display device output by the foot manipulation input device is processed as if it is the signal output from the position display device.

When the foot manipulation input device and the computer are wirelessly connected, the central processing unit 113 processes the key scan code as a wireless key scan code for wireless transmission and reception. That is, as shown in Figs. 10B to 10D, the key identifier code generated by the hand manipulation input device, the key scan code generated by the foot manipulation input device, or the key scan code synthesized by both devices, Generates wireless key scan information to which channel information and error checksum information are added.

The central processor 113 transmits the coordinate values input from the touch pad controller 111 to the computer through the second transceiver.

The process of generating the key scan code to be transmitted to the computer by using the key value input through the hand manipulation input device and the foot manipulation input device by the central processing unit 113 is illustrated in FIG. 12.

The second transceiver 121 transmits the key scan code output from the central processing unit 113 to the computer and receives the reassignment key output from the computer. The second transceiver 121 includes a communication port capable of transmitting and receiving a key scan code and a reassignment key with a computer. The communication port may be any one of a universal serial bus port, a PS / 2 port, or a serial communication port.

The memory 123 stores information necessary for driving and interworking with each of the hand manipulation input apparatus and the foot manipulation input apparatus.

As shown in FIG. 10A, when the foot manipulation input device 101 and the computer 161 are wirelessly connected, the second transceiver 121 may receive the wireless key scan code received from the central processing unit 113. The computer 161 may convert the data into a form that can be transmitted to the computer 161.

The second transceiver 121 may transmit the coordinate value generated by the position display device attached to the foot manipulation input device to the computer. In another embodiment, the second transceiver 121 may further include a communication port, for example, a PS / 2 port or a serial communication port, for transmitting the coordinate value generated by the position display device to a computer.

The touch pad controller 111 includes a touch pad sensor, a coordinate determination circuit, and an interface circuit. When an electrical change occurs in the touch pad by the user's foot contact, the coordinate determination circuit determines the X and Y axis values corresponding to the position where the contact occurs. The generated coordinate values are transmitted to the central processing unit 113 through the interface circuit.

The touch pad controller 111 may be replaced by another position display device, for example, a mouse, a positioning bar, a track ball, or a joystick.

12 is a flowchart illustrating an input processing procedure of a foot manipulation input device according to an embodiment of the present invention. In more detail, the process of generating a key scan code for the foot input device, the key input of the foot manipulation input device, or the key input of both input devices is performed by the foot manipulation input device.

Referring to FIG. 12, in step 125, when a user inputs a key using a hand manipulation input device, a foot manipulation input device, or both input devices sequentially, the foot manipulation input device determines which input device the input is received from. do. The input signal from the hand manipulation input device is a key scan code generated by the general-purpose keyboard and transmitted to the computer. The input signal from the foot manipulation input device is the key scan data assigned to each input key installed in the foot manipulation input device. There is no.

According to the user's skill, the user may input the extension key + the letter key through the hand manipulation input device. Therefore, the key scan code 1 from the hand manipulation input device is directly transmitted to the computer unless the situation is the same as in step 129, i.e., when a key input is waited from the hand manipulation input device after the extension key is input from the foot manipulation input device. If the determination resulted in the input of the hand manipulation input device, the flow proceeds to step 127, after outputting the key scan code 1 input by the hand manipulation input device, the process proceeds to step 125 again. If the result of the determination is an input from the foot manipulation input device, step 129 is reached.

In operation 129, the foot manipulation input apparatus determines whether the key input by the user is a state change key or an extension key. Since the input key of the foot operation input device has different key values according to the basic mode and the assignment mode, check the driving mode of the foot operation input device first, and then use the input key assignment table of the corresponding mode to obtain the key scan data. Convert to 2. The key scan code 2 is preferably equal to the key scan code generated on the general-purpose keyboard. In some cases, the process of converting the key scan data of the foot manipulation input device into the key scan code 2 may be included in step 125. If the result of the determination is a state change key, the control proceeds to step 131 to output the key scan code 2 and then to step 125. If the determination result is an extension key, step 133 is reached.

In step 133, a key input is awaited from the hand manipulation input device. When the key scan code 3 is input from the hand manipulation input device while the user presses the input key of the foot manipulation input device for inputting the extension key + character key, the process proceeds to step 135. After the user presses the input key of the foot manipulation input device, if the user releases the foot from the input key without performing key input through the hand manipulation input device, the process returns to step 125.

In step 135, it is determined whether the key scan code 2 and the key scan code 3 collide. The key scan code collision depends on the transmission method after the key scan code processing and the processing method after the key scan code transmission. The key scan code impulse occurring when using the transmission method after the key scan code processing will be described first. The key scan code collision is (1) when the same extension key input from the foot manipulation input device is input also on the hand manipulation input device, (2) a combination of input keys without a key scan code, (3) Occurs when a combination of input keys corresponding to a special control command occurs. Each case is demonstrated by an example. The user inputs the shift key + letter key through the hand control input device while pressing the shift key of the foot control input device, or the control key + letter key through the hand control input device while pressing the control key of the foot control input device. This is the case in (1). In the case of (2), the user inputs the shift key + alt key through the hand manipulation input device while pressing the control key of the foot manipulation input device. (3) corresponds to a case in which the user inputs the Alt key + Delit key through the hand manipulation input device while pressing the control key of the foot manipulation input device. The key scan code 2 and the key scan code 3 are analyzed to proceed to step 139 if any one of the conditions (1) to (3) is satisfied, otherwise proceed to step 137.

In the case of the processing method after the key scan code transmission, the collision of the key scan code occurs when the same extension key input from the foot manipulation input apparatus is input through the hand manipulation input apparatus. For example, when a user presses a control key of a foot manipulation input device and a key scan code is generated and transmitted to the computer, the user presses a control key of the hand manipulation input device again. That is, when the input key of the hand manipulation input device and the foot manipulation input device having the same key scan code are pressed in sequence, the key scan code processing routine of the computer receives only make codes without break codes for the same key. Done. The key scan code 2 and the key scan code 3 are analyzed to proceed to step 139 if the key input has the same key scan code, and to proceed to step 137 otherwise.

In step 137, if the key scan code 2 and the key scan code 3 do not collide, the key scan code 2 and the key scan code 3 are synthesized to generate the key scan code 4. The synthesis of the key scan code depends on the transfer protocol between the general-purpose keyboard and the computer. (1) The key scan code corresponding to the extension key is inserted into a specific bit or byte of the key scan code for a character key which is usually composed of 2 bytes. Or (2) a method of concatenating each key scan code using a special character code such as a control character or a non-blank character. That is, step 137 is a process of processing the extension key input from the foot manipulation input device and the text key input from the hand manipulation input device to be recognized by the computer as if it is an extension key + character key input from one keyboard. The synthesized key scan code 4 is output in step 141 and goes back to step 125.

In step 139, when the key scan code 2 and the key scan code 3 collide, the key scan code 4 is synthesized after the collision between the key scan code 2 and the key scan code 3 is processed according to a predetermined collision processing routine. The collision processing routine in the case of the transmission method after the key scan code processing will be described first. In order to solve the case where the same extension key input from the foot manipulation input device is also input from the hand manipulation input device, the key scan code 2 is ignored and the key scan code 3 is output to the computer. In order to solve the case of the combination of input keys having no key scan code, priority is given to either the hand manipulation input device or the foot manipulation input device to output only the key scan code from the input device having the higher priority, Ignore key scan codes from low priority input devices. The key scan code processed by step 139 is output in step 141.

13 is an exemplary view showing a combination of a hand manipulation input device, a foot manipulation input device, and a computer according to another exemplary embodiment of the present invention.

Referring to FIG. 13, the hand manipulation input device 270 is coupled between the foot manipulation input device 200 and the computer 280.

Is entered.

In addition, when the user inputs using the hand manipulation input apparatus 270 and the foot manipulation input apparatus 200 simultaneously, the key scan code output from the foot manipulation input apparatus 200 is input by the hand manipulation input apparatus 270. The key scan code corresponding to the received key is input to the computer 280. That is, when the user inputs the s of the hand manipulation input apparatus 270 while pressing the shift key of the foot manipulation input apparatus 200, the hand manipulation input apparatus 270 is configured to be displayed by the user at the hand manipulation input apparatus 270. The same key scan code as that of the shift key + s key ”is generated and input into the computer 280.

Although the foot manipulation input device 200 and the hand manipulation input device 270 and the hand manipulation input device 270 and the computer 280 may be connected by a serial communication cable, respectively, preferably, a universal serial bus By USB). In particular, when the foot manipulation input apparatus 200 further includes a position display apparatus, when the hand manipulation input apparatus 270 is connected to the computer 280 using a serial communication cable, the position display apparatus must be used only by using a separate connection means. The positional data output by the user may be input to the computer 280.

14 is a view illustrating a combination of a foot manipulation input apparatus, a hand manipulation input apparatus, and a computer according to another exemplary embodiment of the present invention, and illustrates an example in which a hand manipulation input apparatus and a computer are wirelessly connected.

Referring to FIG. 14, the hand manipulation input device 271 may wirelessly transmit data input by a user to the computer 281. As a wireless communication method used between computer peripherals, infrared communication (IrDA) may be generally used, and radio frequency (RF) communication may be used.

When the hand manipulation input device 271 is wirelessly connected to the computer 281, the hand manipulation input device 201 transmits a wireless key scan code. The format of the wireless key scan code transmitted by the hand manipulation input device 271 is the same as the format shown in Figs. 10B to 10D.

15A is a block diagram showing the configuration of a hand manipulation input device according to another preferred embodiment of the present invention.

Referring to FIG. 15A, a hand manipulation input device may include a keyboard matrix 203, a scan code generator 205, a central processor 209, a memory 219, a first transceiver 213, and a second transceiver 215. ). Each component is connected as shown in the figure, and the buffer, clock generator and power supply are omitted.

The keyboard matrix 203 has a plurality of input keys composed of character keys and non-magnetic keys as in the conventional hand manipulation input device, and generates key scan data upon receiving key input from a user.

The scan code generation unit 205 generates a key scan code based on the key scan data of the keyboard matrix 203. When the scan code generation unit 205 receives the key scan data, the scan code generation unit 205 generates a key scan code assigned to a default value corresponding to each of the plurality of input keys included in the keyboard matrix 203.

The first transceiver 213 receives the key scan code or the key scan data from the foot manipulation input device. The first transceiver 213 that receives the key scan code or the key scan data from the foot manipulation input device generates an interrupt to notify the central processing unit 209 that the kisscan code or the key scan data has been input from the foot manipulation input device. . The first transceiver 213 includes a communication port capable of receiving a key scan code or key scan data from a foot manipulation input device. The communication port may be any one of a universal serial bus port, a PS / 2 port, or a serial communication port. In another embodiment, the first transceiver 213 may include a universal serial bus port, a PS / 2 port, and a serial port and a port selector. The port selector detects a port to which the foot manipulation input device is connected and transmits a key scan code inputted to the port to the central processing unit 209.

When the hand manipulation input device and the foot manipulation input device are wirelessly connected, the first transceiver 213 may be a wireless transceiver that may wirelessly receive a key scan code from the foot manipulation input device.

The central processing unit 209 transmits the key scan code generated by the scan code generation unit 205 by the key input from the user to the computer through the second transceiver 217.

The central processing unit 209 processes the key scan code or key scan data input from the foot manipulation input device and the key scan code input from the scan code generating unit 205 to synthesize the key scan code to be input to the computer. That is, the central processing unit 209 scans a key generated by a key input by a key input using only a hand manipulation input device by a key input code generated by a user using both a hand manipulation input device and a foot manipulation input device at the same time. Synthesize the keys input by both input devices to be identical to the code. The synthesized key scan code is transmitted to the computer through the second transceiver 217.

The central processing unit 209 operates differently according to the basic mode and the assignment mode. To use the foot manipulation input device in the assignment mode, the user may assign a reassignment key to the foot manipulation input device through a user input screen. . The reassignment key is transmitted to the hand manipulation input device through the first transceiver 217, and the central processing unit 209 stores the key in the key assignment table of the memory 219. The central processing unit 209 refers to the key assignment table stored in the memory 219 every time a key scan code or key scan data is input from the foot manipulation input apparatus, and assigns the key scan code inputted from the foot manipulation input apparatus to the reassignment key. Change to the corresponding key scan code. The changed key scan code and the key scan code input from the hand manipulation input device are synthesized in the central processing unit 209 and transmitted to the computer. In another embodiment, the change to the reassigned key scan code may be performed at the foot manipulation input device. To this end, the reassignment key input by the user may be transmitted to the foot manipulation input apparatus and stored in a memory located in the foot manipulation input apparatus.

In another embodiment, each input key is based on one key, and may also reassign a composite key combining two or more keys. That is, in order to produce the same effect as pressing the control key and the shift key at the same time, the control key and the shift key may be reassigned to one input key.

In another embodiment, an operation key included in a position display device (eg, a mouse) not installed in the foot operation input device may be assigned to the input key. For example, when using a web browsing program such as Internet Explorer, right-clicking a mouse displays a pop-up menu containing simple operation commands on the screen. The user selects the menu again and clicks the left mouse button to move to the previous web page or the next web page, and then clicks an operation command on the menu or inputs a letter key (such as B or O in Internet Explorer). To simplify this series of input operations, you can assign compound keys to input keys, such as right-clicking the mouse (right mouse key) + selecting the previous web page navigation command and then left-clicking the mouse (left key or character key). have. To this end, a separate processing program should be installed in the electronic information processing apparatus so that the operation key signal of the position display device output by the foot manipulation input device is processed as if it is the signal output from the position display device.

When the hand manipulation input device and the computer are wirelessly connected, the central processing unit 209 processes the key scan code as a wireless key scan code for wireless transmission and reception. That is, as shown in Figs. 10B to 10D, the key identifier code generated by the hand manipulation input device, the key scan code generated by the foot manipulation input device, or the key scan code synthesized by both devices, Generates wireless key scan information to which channel information and error checksum information are added.

The process of the central processing unit 209 to generate a key scan code to be transmitted to the computer using the key values input through the hand manipulation input device and the foot manipulation input device is illustrated in FIG. 16B.

The second transceiver 217 transmits the key scan code output from the central processing unit 209 to the computer, and receives the reassignment key output from the computer. The second transceiver 217 includes a communication port capable of transmitting and receiving a key scan code and a reassignment key with a computer. The communication port may be one of a universal serial bus port, a PS / 2 port, or a serial communication port.

The memory 219 stores information necessary for driving and interworking with each of the hand manipulation input apparatus and the foot manipulation input apparatus.

15B is a block diagram showing the configuration of a foot operation input device according to another preferred embodiment of the present invention.

Referring to FIG. 15B, the foot manipulation input device includes a keyboard matrix 221, a scan code generator 223, an output controller 227, a transceiver 235, and a keypad controller 229. Each component is connected as shown in the figure, and the buffer, clock generator and power supply are omitted.

The keyboard matrix 221 includes a plurality of input keys, and generates key scan data when a key input is received from a user.

The scan code generation unit 223 generates a key scan code based on the key scan data of the keyboard matrix 221. When the scan code generation unit 223 receives the key scan data, the scan code generation unit 223 generates a key scan code assigned as a default value corresponding to each of the plurality of input keys included in the keyboard matrix 221. When operating in the assignment mode, the process of changing the key scan code is performed once more in the hand manipulation input device, so that the key scan data can be transmitted to the hand manipulation input device without changing to the key scan code.

The output control unit 209 distinguishes the key scan code input from the scan code generation unit 205 and the coordinate values input from the keypad control unit 229 and applies them to the transmission / reception unit 235.

The touch pad controller 229 includes a touch pad sensor, a coordinate determination circuit, and an interface circuit. When an electrical change occurs in the touch pad by the user's foot contact, the coordinate determination circuit determines the X and Y axis values corresponding to the position where the contact occurs. The generated coordinate values are transmitted to the output controller 227 through the interface circuit.

The touch pad controller 229 may be replaced with another location display device, for example, a mouse, a positioning bar, a track ball, or a joystick.

The transmitter / receiver 235 transmits the key scan code, key scan data or coordinate values applied from the output controller 227 to the hand manipulation input device and receives a control command.

When the foot manipulation input device and the hand manipulation input device are wirelessly connected, the transceiver 235 may be a wireless transceiver that may wirelessly transmit a key scan code to the hand manipulation input device.

16A is a flowchart illustrating an input processing procedure of a foot manipulation input device according to another exemplary embodiment of the present invention.

Referring to FIG. 16A, it is determined in step 237 whether a key input or a keypad input. If the determination result is a keypad input, the process proceeds to step 239 to generate a coordinate value corresponding to the keypad, and outputs the coordinate value to the hand manipulation input device in step 243.

If the determination result is a key input, a key scan code corresponding to a key is generated in step 241, and the key scan code generated in step 243 is output to a hand manipulation input device.

16B is a flowchart illustrating an input processing procedure of a hand manipulation input device according to another exemplary embodiment of the present invention. In more detail, the process of generating a key scan code for the key input of the hand manipulation input apparatus, the key input of the foot manipulation input apparatus, or the key input of both input apparatuses is performed by the hand manipulation input apparatus.

Referring to FIG. 16B, in step 245, when a user inputs a key using a hand manipulation input device, a foot manipulation input device, or both input devices in sequence, the hand manipulation input device determines which input device has received an input. do. The input signal from the hand manipulation input device is a key scan code generated by the general-purpose keyboard and transmitted to the computer. The input signal from the foot manipulation input device is the key scan data assigned to each input key installed in the foot manipulation input device. There is no.

According to the user's skill, the user can input the extension key + the character key only through the hand manipulation input device. Therefore, the key scan code 1 of the hand manipulation input device is directly transmitted to the computer unless the situation is the same as in step 251, that is, when the key is waited for by the hand manipulation input device after the extension key is input from the foot manipulation input device. If the determination resulted in the hand manipulation input device input, the flow proceeds to step 247 to generate a key scan code 1. The generated key scan code 1 is output to the computer in step 249 and then goes back to step 245. If the result of the determination is an input from the foot manipulation input device, the flow proceeds to step 251.

In operation 251, the hand manipulation input apparatus determines whether the key input by the user is a state change key or an extension key. Since the input key of the foot manipulation input device has different key values according to the basic mode and the assignment mode, the driving mode of the foot manipulation input device is checked first, and the key scan code is converted using the input key assignment table of the corresponding mode. The converted key scan code (key scan code 2) is preferably equal to the key scan code generated on the general-purpose keyboard. In some cases, the process of converting the key scan code of the foot manipulation input device may be included in step 245. If it is determined that the state transition key is found, the process proceeds to step 253 to output the key scan code 2 and then goes back to step 245. If the determination result is an extension key, step 255 is reached.

In step 255, the user waits for a key input through a hand manipulation input device from the user. If the user presses the input key of the foot manipulation input device for the extension key + character key input and there is a key input (key scan code 3), the flow proceeds to step 259. After the user presses an input key of the foot manipulation input apparatus and releases a foot from the input key of the foot manipulation input apparatus without performing a key input through the hand manipulation input apparatus, the flow returns to step 245.

In step 257, it is determined whether the key scan code 2 and the key scan code 3 collide. Whether the key scan code collides depends on the transmission method after the key scan code processing and the processing method after the key scan code transmission. Since the criteria for determining the collision have already been described above with reference to FIG. 12, a description thereof will be omitted. The key scan code 2 and the key scan code 3 are analyzed to proceed to step 259 if a conflict occurs, otherwise proceed to step 261.

In step 259, if the key scan code 2 and the key scan code 3 do not collide, the key scan code 2 and the key scan code 3 are synthesized to generate the key scan code 4. The synthesis of the key scan code depends on the transfer protocol between the general-purpose keyboard and the computer. (1) The key scan code corresponding to the extension key is inserted into a specific bit or byte of the key scan code for a character key which is usually composed of 2 bytes. Or (2) a method of concatenating each key scan code using a special character code such as a control character or a non-blank character. That is, step 259 is a process of processing such that the extension key input from the foot manipulation input device and the text key input from the hand manipulation input device are recognized by the computer as if it is an expansion key + character key input from one keyboard. The synthesized key scan code 4 is output in step 263 and goes back to step 245.

In step 261, when the key scan code 2 and the key scan code 3 collide, the key scan code 4 is synthesized after the collision between the key scan code 2 and the key scan code 3 is processed according to a predetermined collision processing routine. The collision processing routine in the case of the transmission method after the key scan code processing will be described first. In order to solve the case where the same extension key input from the foot manipulation input device is also input from the hand manipulation input device, the key scan code 2 is ignored and the key scan code 3 is output to the computer. In order to solve the case of the combination of input keys having no key scan code, priority is given to either the hand manipulation input device or the foot manipulation input device to output only the key scan code from the input device having the higher priority, Ignore key scan codes from low priority input devices. The key scan code processed by step 261 is output in step 263.

If the determination result is that the key scan code is input from the foot manipulation input device, the flow proceeds to step 309.

In step 309, the foot manipulation input device driving program determines whether the key input by the user is a state change key or an extension key. Since the input key of the foot manipulation input device has different key values according to the basic mode and the assignment mode, the driving mode of the foot manipulation input device is first checked, and then the key scan code is converted using the key assignment table of the corresponding mode. The converted key scan code (key scan code 2) is preferably equal to the key scan code generated on the general-purpose keyboard. In some cases, the process of converting the key scan code of the foot manipulation input device may be included in step 303. The input key of the foot manipulation input device is based on one key, and a composite key combining two or more keys can also be reassigned. That is, in order to produce the same effect as pressing the control key and the shift key at the same time, the control key and the shift key may be reassigned to one input key.

In another embodiment, an operation key included in a position display device (eg, a mouse) not installed in the foot operation input device may be assigned to the input key. For example, when using a web browsing program such as Internet Explorer, right-clicking a mouse displays a pop-up menu containing simple operation commands on the screen. The user selects the menu again to move to the previous web page or the next web page, clicks the left mouse button, clicks an operation command on the menu, or inputs a letter key (such as B or O in Internet Explorer). To simplify this series of input operations, you can assign compound keys to input keys, such as right-clicking the mouse (right mouse key) + selecting the previous web page navigation command and then left-clicking the mouse (left key or character key). have. To this end, the method may further include processing an operation key signal of the position display device output by the foot manipulation input device as if it is a signal output from the position display device, and then transmitting the signal to the operating system.

If it is determined that the state conversion key is found, the process proceeds to step 311 and the key scan code 2 is converted into a character code usable by the computer, and then the process proceeds to step 313. In step 313, the character code is output to the operating system, and then the flow goes to step 303 again. If the determination result is an extension key, step 315 is reached.

In step 315, a key input from the user's hand manipulation input device is awaited. If the user presses an input key of the foot manipulation input device for the extension key + character key input and there is a key input (key scan code 3), the flow proceeds to step 317. After the user presses the input key of the foot manipulation input apparatus and releases a foot from the input key of the foot manipulation input apparatus without performing key input through the hand manipulation input apparatus, the flow returns to step 303.

In step 317, it is determined whether the key scan code 2 and the key scan code 3 collide. The key scan code 2 and the key scan code 3 are analyzed to proceed to step 319 if a conflict occurs, otherwise proceed to step 321.

In step 319, if the key scan code 2 and the key scan code 3 collide, the collision between the key scan code 2 and the key scan code 3 is processed according to a predetermined collision processing routine, and then converted to a character code, and the flow proceeds to step 323. . In step 323 the character code is sent to the operating system.

In step 321, if the key scan code 2 and the key scan code 3 do not collide, the key scan code 2 and the key scan code 3 are synthesized and converted into a character code, and the flow proceeds to step 323. In step 323, the foot manipulation input device driving program transmits the character code to the operating system and then moves back to step 303 to wait for the next key input by the user.
