Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention enables a pointing device such as a tablet device to be used in the same manner as a mouse in a data processing device such as a workstation, and an input means such as an ID card reader can be used in the same manner as a keyboard. This invention relates to a method for converting input data into keyboard/mouse data.

2. Description of the Related Art In a data processing apparatus, a keyboard and a mouse are generally connected as input devices used for conversation processing with an operator. Here, the keyboard is used as a means for inputting characters, etc., and the mouse is used as a pointing input means.

[0003] Furthermore, there has been provided an input/output window system that allows multiple windows to be opened on a bitmap display and multiple pieces of information to be referenced at the same time.

By the way, in a general window system,
Only the keyboard and mouse are supported as input devices and instruction input devices.

[0005] Other input devices for conversation with the operator include tablet devices. Tablet devices are used to input coordinate values, but this is only valid when a CAD application is running, and cannot be used as a normal pointing device. However, there is a demand for operators using tablet devices to be able to use the tablet device as a pointing device in a window system in the same way as a mouse.

There is also a demand for input devices such as ID card readers to be able to process input data in the same way as input data from a keyboard. For example, when starting up a device and using an application program, there is a system that allows the user to enter the operator's name and password from the keyboard, check this, and then use this when the user is identified as authorized to use the application. .

[0007] In such a case, if the name and password were written on the ID card and the name and password read by the ID card reader could be used in the same way as keyboard input, there would be no need to input these from the keyboard.
Furthermore, applications running on a window system can use input data without having to be aware of input devices such as ID cards and readers.

[0008] As described above, there are several input devices such as IC card readers and tablet devices that are connected and controlled using the RS232C interface standard, and although they have the same functions as a keyboard/mouse, applications are not aware of them. There is a need for a control method that does not require special programs for each device.

[0009] In conventional personal computers and workstations, when an input device other than a keyboard or mouse is used in the same way as a keyboard or mouse, an application or window system must consciously control the input device directly. This provides operators with the same operability as a keyboard or mouse.

Alternatively, a control method is provided in which a dedicated control program is prepared in the system for each input device, and the control program converts the data into keyboard or mouse data and passes the data to the keyboard or mouse control program in the system. Supported by

[0011]

[Problem to be Solved by the Invention] Conventionally, when a window system or even an application is aware of the input devices connected to it, the functionality of the window system/application is expanded each time the number of connected input devices increases. Must be corrected. Furthermore, even if a dedicated control program is prepared for each of these input devices in the system, each time the number of connected input devices increases, a control program dedicated to that device must be prepared and the system must be changed.

Therefore, an object of the present invention is to provide a keyboard/mouse for input data that allows applications to use these input devices via the window system in the same way as keyboards and mice without changing the window system application. The purpose is to provide a data conversion method.

[0013]

[Means for Solving the Problems] In order to achieve the above object, in the present invention, as shown in FIG.
, an interface control section 2, a window control section 3, a conversion information holding section 4, a conversion information setting section 5, a switching connection section 6, a keyboard control section 7, and a mouse control section 8. In addition to the keyboard 10 and mouse 20, the interface control unit 2 includes
An input device 11 such as a card reader or hand scanner, and a pointing input device 21 such as a tablet device or a dial box are connected.

The conversion information holding unit 4 stores information for each input device and pointing input device, such as conversion information for IC card readers, conversion information for hand scanners, conversion information for tablets, and conversion information for dial boxes. Conversion information 4-0, 4-1, . . . is held.

The keyboard control section 7 includes a conversion processing section 7-0.
is provided, and when an IC card reader is connected as an input device, the conversion information for the IC card reader is read from the conversion information holding unit 4 and set in the conversion processing unit 7-0. Converts input data from a card reader into data similar to a keyboard.

Similarly, the mouse control section 8 also includes a conversion processing section 8.
-0 is provided and a tablet device is used as a pointing input device, the conversion information for the tablet device is read from the conversion information holding unit 4 and set in the conversion processing unit 8-0. Convert input data from a tablet device into data similar to a keyboard.

[0017]

[Operation] According to the present invention, when an IC card reader is used, for example, the interface control unit 2 determines this, and the conversion information setting unit 5 reads the corresponding conversion information from the conversion information holding unit 4, and is output to the keyboard control section 7 and set in the conversion processing section 7-0.

Data inputted from the IC card reader to the keyboard control section 7 is processed by the conversion processing section 7-
0 is converted into data in the same format as keyboard data, and sent via the switching connection 6 to the window control unit 3.
and processing is performed based on the running application program, for example 3-0.

Furthermore, when data from the tablet is input to the interface control section 2, conversion information corresponding to the tablet is read out from the conversion information holding section 4 and sent to the conversion processing section 8- of the mouse control section 8. It is set to 0, and based on this, it is converted into data in the same format as mouse data, and is processed by the window control unit 3 and the running application.

Of course, input from the keyboard 10 or mouse 20 is directly input to the window control unit 3 as before.

[0021]

[Embodiment] An embodiment of the present invention will be explained based on FIGS. 2 to 4. FIG. 2 is a configuration diagram of an embodiment of the present invention, FIG. 3 is a data unit explanatory diagram, and FIG. 4 is a schematic explanatory diagram of keyboard control section/mouse control.

In FIG. 2, the same symbols as in FIG. 1 indicate the same parts, and 9 is a setup instruction section.

The main body hardware section 1 is, for example, the main body part of a workstation.

[0024] The interface control unit 2 controls the keyboard 1
0, mouse 20, input device 11 such as an IC card reader
, a pointing input device 21 such as a tablet device, etc., using, for example, the RS232C interface standard.As will be described later, it also cuts out data units as shown in FIG.

The window control section 3 sets a window, changes its size, and rewrites a bitmap using data from the mouse.

As described above, the conversion information holding unit 4 stores conversion information 4-0, 4- for each input device and pointing input device.
1... is held. Here, use an IC card reader or OC.
Conversion information for input devices such as R hand scanners is mainly a conversion table that converts data in the same way as a keyboard, and conversion information for pointing input devices such as tablet devices and dial boxes is a conversion table that converts numerical values to those for a mouse. It's a table. Furthermore, if an offset is applied, there may be cases where operations such as subtraction are required, such as conversion processing after subtracting the offset, or there may be cases where it is necessary to expand 1-byte data to 2-byte data. Therefore, commands or programs may also be entered.

The conversion information setting section 5 extracts predetermined conversion information from the conversion information holding section 4. It performs various control information setting processes such as setting the transfer rate (baud rate) to the external interface control unit 2, and performs device recognition processing to determine whether connected devices such as input devices and pointing input devices are correctly connected. When performing direct control such as issuing a control order to a device and acquiring information, use the conversion mode OFF.

The switching connection section 6 selectively sends signals from the keyboard control section 7 and mouse control section 8 to the window control section 3 and conversion information setting section 5, and selectively sends signals from the conversion information setting section 5. It is selectively sent to the keyboard control section 7 and mouse control section 8.

[0029] The keyboard control unit 7 includes an IC card reader,
It converts signals from an input device such as an OCR hand scanner into a keyboard signal, and includes a conversion information set section 7-0 that holds conversion information for each of these input devices.

The mouse control unit 8 converts signals from pointing input devices such as tablet devices and dial boxes into mouse signals, and includes a conversion information set unit 8- which holds conversion information for each pointing input device.
has 0. This conversion information can not only simply replace numbers, but also include arithmetic functions and the like.

For example, the X, Y data is 80 (hexadecimal) +
, 80 (hexadecimal) + Y may be input from the pointing input device, but in this case "80"
It is necessary to subtract, convert, and send to the window system, and commands for such operations can be written. It is also possible to write a command to expand 1-byte data into 2-byte data and output it as 2-byte data. This calculation is performed by the data conversion processing section 8-1 in FIG. 4 based on a command from the conversion processing section 8-0, and then converted into mouse data based on the conversion table data of the conversion information setting section 8-0.

The setup instruction section 9 instructs the conversion information setting section 5 to read conversion information for each device from the conversion information holding section 4 according to the type of the input device 11 and pointing input device 21 connected to the interface control section 2. It provides setup instructions.

Next, the operation of the present invention will be explained, for example, when a tablet device is connected to the interface control section 2.

When the pointing input device 21 is connected, the interface control section 2 notifies the conversion information setting section 5 of this. At this time, the conversion mode is OFF. As a result, the conversion information setting section 5
The first ID sent from 1 is decoded to determine its type. For example, it is determined that the device is a tablet device. Then, based on the instructions from the setup instruction section 9, conversion information for, for example, a tablet device is read from the conversion information holding section 4, and is sent to the conversion information setting section 8 of the mouse control section 8 shown in FIG. 4 via the switching connection section 6. -0 is entered.

This conversion information includes conversion mode setting instructions, data unit length check specifications, conversion table data, header length, commands, etc., as shown in the settings of various control information in FIG. Among these, the conversion table data and commands are entered in the conversion information set section 8-0, and the check specification of the data unit length, the unit length (which can also be specified for each header value), and the header length at the beginning of the data unit (0
-N), and finally turn on the conversion mode. Multiple sets of data length and header value/length can be set. When setting multiple sets, it is sufficient if the value matches any one of the multiple set values.

Next, when the operator operates the tablet device, received data R4 and R5 as shown in FIG.
, R6 and R7 are transmitted to the interface control section 2. At this time, the interface control unit 2 is instructed to set a threshold Th0 for creating a data unit, and the time T3 between the received data R4 and the previous received data R3 is T.
3>Th0 and time T4 of R4 to R7
.about.T6 are all less than Th0, and if the time T7 with respect to the next received data R8 is T7>Th0, the received data R4 to R7 are determined to be a data unit and are collectively notified to the mouse control section 8.

By the way, the input data of the tablet device is
In this case, the first received data R4 indicates the device ID, the received data R5 indicates button information, and the received data R6
, R7 indicate the X and Y coordinates.

Therefore, in the case of such a data unit, when the conversion mode is ON, the received data R4 to R7
A unit length check is performed, and then the header part, if any, is deleted. In this example, R4 is a header, so it is deleted. The remaining data is then converted into mouse data via the data conversion processing section 8-1 based on the conversion table data held in the conversion information setting section 8-0. For example, when the input data after removing the header portion is 0x08, it is replaced with the data located at 0x08 in the conversion table.

[0039] In this selection of the converted data portion, the data that is the target pair is notified to the conversion information setting unit 5. Further, when the conversion information setting section 5 directly reads data from an input device, pointing input device, etc., the conversion mode may be turned OFF.

By the way, the output data from the mouse 20 is unit data composed of received data R1, R2, and R3 in FIG. 3, where R1 is button information and R2 is
, R3 indicate the X, Y coordinates. Therefore, if the header portion R4 is deleted from the received data R4 to R7, it will have the same format as the mouse output, so it is sufficient to convert this.

As mentioned above, since some data has an offset, for example, when the offset is 80, it is determined that an offset exists for data larger than this, and the data conversion shown in FIG. 4 is performed as described above. The processing unit 8-1 may perform calculations such as subtraction, and the conversion information setting unit 8-0 may convert this.

Note that when the tablet device is directly used by an application such as CAD, the tablet device is opened. As a result, the input data from the tablet device is transmitted to the window control unit 3 without being converted by the mouse control unit 8, and is processed by, for example, the CAD application 3-n. Then, when the tablet device is closed, the conversion is controlled by the mouse control unit 8.

When an input device such as an IC card reader or an OCR hand scanner is used, the keyboard control section 7
The keyboard control unit 7 is also configured similarly to the mouse control unit 8 shown in FIG.
Explanation regarding this will be omitted.

[0044] Furthermore, although the above description has been made regarding examples of RS232C type input devices and pointing input devices, the present invention is not limited to only RS232C type input devices.

[0045]

According to the present invention, it is not necessary to modify the application program or the window system even when using an input device such as an IC card reader as a keyboard and a pointing input device such as a tablet device as a mouse. All you need to do is prepare the conversion information, without having to prepare any special conversion programs, etc.
Input data from these devices can be processed as if it were from a keyboard or mouse, so these devices can be used to handle operator-to-system or operator-to-window control system interactions. I can do it.
