Description

  The present invention relates to a calibration device that performs calibration of a touch panel.

  Some computers, such as industrial computers, use a touch panel display. The touch panel display functions as a monitor of a computer, and also functions as an input / operation device for operating a computer by directly or indirectly touching and operating the touch panel display with a finger or a touch pen or the like.

  In such a touch panel display, an operation display such as an icon or a switch is displayed on the touch panel display by an application or the like. By touching the operation display with a finger or the like, the computer is operated in accordance with the operation performed on the operation display. The operation by the finger or the like is determined by identifying the position at which the finger or the like touches the touch panel display by a change in electric resistance or the like and collating with the position of the operation display. Therefore, in the touch panel display, it is necessary to accurately recognize which position on the touch panel display the position touched by the finger or the like. Along with this, calibration is performed to calculate a correction value for establishing a correlation between an actual position touched by a finger or the like and a position recognized as touched on the touch panel display.

  However, calibration in a computer using a conventional touch panel display (hereinafter also referred to as a touch panel computer) has been performed using a dedicated application that operates depending on the OS. In addition, since the calibration is performed depending on the OS, the correction value obtained by the calibration is stored in the registry. Therefore, when the OS is reinstalled or the like, the correction value already obtained is deleted, and there is a problem that it is necessary to perform the calibration again. In addition, there is a problem that calibration is difficult while other applications are operating. In particular, when the touch panel computer is an embedded system, when the touch panel computer is activated, a dedicated application is automatically activated following the activation of the OS. Therefore, in order to activate the calibration, the operation of the OS is maintained. There is a problem that it is necessary to stop the dedicated application of the embedded system and to start the application for calibration, which takes time for calibration.

  In order to solve the above-mentioned problems, the calibration device of the present invention aims to carry out calibration easily and simply.

In order to achieve the above object, the calibration device of the present invention is a calibration device that performs calibration of a touch panel display, and includes a storage device in which a BIOS is stored, and calibration data which is operated on the BIOS A calibration program to be generated and a control device for executing the calibration program are characterized.

  As described above, by performing calibration using the calibration program operating on the BIOS, even when the touch panel computer is operating, the calibration program can be easily executed by activating the BIOS. Calibration can be easily and easily performed.

  Further, it may further include a non-volatile storage device for storing the calibration data generated by the calibration program.

  As described above, by performing calibration using a calibration program operating on the BIOS, the calibration program can be easily executed by activating the BIOS even during operation of the touch panel computer. At the same time, instead of writing the correction value obtained by calibration into the registry, the calculated calibration data is stored in the non-volatile storage device. Therefore, when the OS is reinstalled or the like, the correction value is not lost by resetting the registry, and the calibration data is continuously maintained in the nonvolatile storage device regardless of the state of the OS. Therefore, calibration can be easily and easily performed.

  Furthermore, a calibration device according to the present invention is a calibration device that performs calibration of a touch panel display, and a calibration program that generates calibration data, a control device that executes the calibration program, and the calibration program And a non-volatile storage device for storing the calibration data.

  As described above, instead of writing the correction value obtained by calibration in the registry, the calculated calibration data is stored in the non-volatile storage device. Therefore, even if calibration is performed not only on the BIOS but also on the OS, the correction value is not lost by resetting the registry when the OS is reinstalled, etc., regardless of the state of the OS. Instead, calibration data continues to be maintained in non-volatile storage. Therefore, calibration can be easily and easily performed.

  The calibration program further includes a touch panel signal reception unit that receives an indication position of which position on the touch panel display is indicated, and an image control unit that causes an image to be displayed on the touch panel display. An indication mark is displayed on a specific display position on the touch panel display, and the indication position when indicating the indication mark is obtained from the touch panel signal receiving unit, and the difference between the indication position and the indication position is obtained. Preferably, calibration data is generated.

  Thereby, calibration can be performed reliably.

  In addition, the touch panel display may be used as a display in an embedded system in which a dedicated application is automatically activated following the activation of the OS.

  In the conventional calibration apparatus, in the case of an embedded system, calibration is only possible after stopping the dedicated application and activating only the OS. By using the calibration program operating on the BIOS 10, the calibration program can be easily executed by starting the BIOS without stopping the dedicated application and restarting only the OS, which is easy and easy. Calibration can be performed. Further, also in the embedded system, the calculated calibration data can be stored in the non-volatile storage device, instead of writing the correction value obtained by the calibration into the registry. In this case, when the OS is reinstalled or the like, the correction value is not lost by resetting the registry, and the calibration data is continuously maintained in the nonvolatile storage device regardless of the state of the OS. Therefore, calibration can be easily and easily performed.

  As described above, the calibration device of the present invention can perform calibration easily and easily.

  The touch panel computer can operate a touch panel computer, an application operating on the touch panel computer, and the like on the touch panel display. At this time, an operation display such as an icon is displayed on the touch panel display, and the operation is performed by operating the operation display with a finger, a touch pen or the like. The operation with a finger or the like is performed by touching or sliding the operation display directly or indirectly.

  In each operation display, information on a display position such as coordinates at which the user is displayed is specified. The touch panel display is configured such that when the touch panel display is operated with a finger or the like, the position on the touch panel display touched by the finger or the like or the operation of the finger or the like can be detected. The touch panel display can detect a pressure change, a change in electric resistance value, and the like in each portion of the surface. And the position where these changed is detected as a position which a finger etc touched, and it is the composition by which operation of a slide etc. is detected by these time-dependent change. The touch panel computer detects the operation display and how it is operated from the designated position or operation of the finger or the like detected in this manner and the display position of the operation display, thereby performing the operation such as the touch panel display or the application. Accept

  The display position is specified at which position on the touch panel display programatically. However, due to a change in setting of the touch panel display, hardware deterioration due to age, hardware characteristics, etc., even if the same position is displayed, a slight deviation may occur in the display position. Similarly, although the pointing position touched by a finger or the like is detected on the touch panel display, the detection accuracy is not necessarily constant. Therefore, it is necessary to calibrate the display position and the designated position touched by a finger or the like. In general calibration, calibration data, which is a correction value, is calculated from the amount of deviation between the display position and the indicated position touched by a finger or the like, and the calibration data achieves consistency between the display position and the indicated position. .

  The present invention relates to a calibration apparatus that performs such calibration.

  First, the outline of the calibration device of the present invention will be described with reference to FIG.

  The calibration program 4 is a program that operates on the BIOS 10 under the control of the CPU 12. The calibration program 4 displays a plurality of calibration operation displays on the touch panel display, and performs calibration by touching each operation display with a finger or the like. Calibration data 6, which is a correction value, is calculated by detecting the designated position touched by a finger or the like and calculating the amount of deviation in comparison with the display position of the corresponding operation display. Then, the calculated calibration data 6 is stored in the non-volatile memory 8 instead of updating the registry. The details of the calibration will be described later.

  As described above, calibration can be performed easily and simply by performing calibration using the calibration program 4 operating on the BIOS 10. That is, even during operation of the touch panel computer, the calibration program 4 can be easily executed by activating the BIOS 10. Moreover, even a touch panel computer in which a dedicated application always operates in the embedded system can operate on the BIOS 10, so calibration is performed without performing a special procedure such as stopping the dedicated application while activating the OS. be able to.

  Further, instead of writing the correction value to the registry, the calculated calibration data 6 is stored in the non-volatile memory 8. Therefore, when the OS is reinstalled or the like, the correction value is not lost by resetting the registry, and the calibration data 6 is maintained in the non-volatile memory 8 regardless of the state of the OS. Therefore, calibration can be easily and easily performed.

  Here, the configuration and operation of the touch panel display will be described with reference to FIG.

  FIG. 2 is a diagram for explaining a touch panel display.

  Various displays are performed on the touch panel display 14 in accordance with the operation of the touch panel computer. Among them, the operation display 16 related to the operation of the touch panel computer, the application, etc. is also displayed. By operating the operation display 16 with a finger 20 or the like, the touch panel computer is operated. As for each operation display 16, the display position where self is displayed is specified. For example, the coordinates on the touch panel display 14 of the central point 18 of each operation display 16 are specified, and it is recognized that a predetermined range around the coordinates is the corresponding area of the operation display 16. As described above, the pointed position of the touched finger 20 or the like is detected by a change in electric resistance value or the like, and the pointed position is recognized as, for example, coordinates on the touch panel display 14. Then, it is determined that the operation display 16 is touched by detecting that the finger 20 or the like is touched in the area specified as each operation display 16. In addition, by detecting that the electric resistance value changes with time in the area of the operation display 16, it is detected that the finger 20 or the like has slid the operation display 16. The touch panel display 14 can detect which operation display 16 has been operated and how it is operated from the operation of the finger 20 or the like and the coordinates thereof, and accordingly, receives the operation of the touch panel computer, the application, etc. Can.

  In addition, although the tablet was illustrated as a touch-panel display in FIG. 2, the touch-panel display provided separately from the main body of the computer may be sufficient.

  Next, a specific configuration example of the calibration device of the present invention will be described using FIG.

  FIG. 3 is a view for explaining the schematic configuration of the touch panel computer of the present invention.

  As shown in FIG. 3, the calibration apparatus 2 includes a calibration program 4 for performing calibration, a non-volatile memory 8 for storing calibration data 6, a BIOS 10 for operating the calibration program 4, a BIOS 10 and a calibration And at least a control device such as the CPU 12 that executes the program 4. Furthermore, the ROM 24 storing the BIOS 10 and the calibration program 4 can be provided. In addition, an image control unit 26 that controls the display of an image on the touch panel display 14 can be provided under the control of the CPU 12. The image control unit 26 also controls display of an operation display 16 (see FIG. 2) and an instruction mark that is an operation display for calibration displayed by calibration described later. The image control unit 26 manages coordinates of display positions such as the operation display 16 (see FIG. 2) and an instruction mark. In addition, the touch panel signal reception unit 28 may be provided to receive a touch panel signal according to an operation performed on the touch panel display 14 and transmit the touch panel signal to the CPU 12. The touch panel signal receiving unit 28 receives, as one touch panel signal, the coordinates of the designated position, which is the position at which the finger 20 (see FIG. 2) or the like is operated on the touch panel display 14. The CPU 12 compares the coordinates of the display position managed by the image control unit 26 with the coordinates of the designated position received via the touch panel signal reception unit 28, and recognizes the content of the operation performed on the touch panel display 14, Control according to it. In addition, an auxiliary storage device 30 may be provided in which various programs other than the OS and the calibration program 4 are stored. When the touch panel computer is an industrial computer or the like dedicated to the embedded system, the dedicated application is stored in the auxiliary storage device 30. The calibration program 4 may also be stored in another storage device such as the auxiliary storage device 30 as long as it operates on the BIOS 10.

  The calibration program 4 is a program that operates on the BIOS 10 under the control of the CPU 12. The calibration program 4 displays instruction marks, which are operation displays for a plurality of calibrations, on the touch panel display, and performs calibration by touching each of the instruction marks with a finger or the like. The calibration data 6, which is a correction value, is calculated by detecting the designated position touched by a finger or the like and calculating the amount of deviation in comparison with the display position of the corresponding designation mark. Then, the calculated calibration data 6 is stored in the non-volatile memory 8 instead of updating the registry. The details of the calibration will be described later.

  As described above, calibration can be performed easily and simply by performing calibration using the calibration program 4 operating on the BIOS 10. That is, even during operation of the touch panel computer, the calibration program 4 can be easily executed by activating the BIOS 10. Moreover, even a touch panel computer in which a dedicated application always operates in the embedded system can operate on the BIOS 10, so calibration is performed without performing a special procedure such as stopping the dedicated application while activating the OS. be able to. For example, the calibration program 4 can be easily activated by restarting the OS while the dedicated application is operating and activating the BIOS while the OS is restarted. Therefore, calibration can be easily and easily performed.

  Further, the calculated calibration data 6 is stored in the non-volatile memory 8 instead of writing the correction value obtained by the calibration into the registry. Therefore, when the OS is reinstalled or the like, the correction value is not lost by resetting the registry, and the calibration data 6 is maintained in the non-volatile memory 8 regardless of the state of the OS. Therefore, calibration can be easily and easily performed. At this time, the calibration program 4 is not limited to operating on the BIOS 10, and may operate on an OS or the like.

  Further, when the touch panel computer is a general purpose system, the general purpose system is used for various applications and usage methods, so generally, at the time of sale, the calibration program is not installed in the touch panel computer, and the user independently performs the calibration program. The calibration was done. On the other hand, since the calibration program 4 operating on the BIOS 10 can be easily configured without depending on the application or the usage method, the calibration program 4 is created and installed in advance even in a general-purpose system. Becomes easy. Therefore, calibration can be easily and easily performed.

  Furthermore, by using the calibration program 4 operating on the BIOS 10, the calibration program 4 can be executed even in a state in which the OS is not installed. Therefore, calibration can be performed at the manufacturing stage of the touch panel computer. As a result, the need for performing calibration after shipping of the touch panel computer can be reduced, and the user may be able to use the touch panel computer without performing calibration. Therefore, calibration can be easily and easily performed.

  Next, the implementation method of a calibration is demonstrated using FIGS. 2-5.

  FIG. 4 is a view exemplifying a BIOS screen for starting the calibration program of the present invention, and FIG. 5 is a view exemplifying a screen display during calibration of the present invention.

  As described above, the calibration program 4 operates on the BIOS 10. Therefore, first, the BIOS 10 is activated. For example, if the OS or the dedicated application is running, the OS is restarted, and the BIOS 10 is started during the restart. When the BIOS 10 is started, the BIOS screen 32 as shown in FIG. 4 is displayed on the touch panel display 14 .

  Next, the calibration program 4 is started to carry out the calibration. The BIOS screen 32 displays a menu for executing various processes. In order to start the calibration program 4, the start menu 34 of the calibration program 4 is selected from the menu.

  Next, when the calibration program 4 is started, a calibration screen 36 as shown in FIG. 5 is displayed.

  Next, when the calibration screen 36 is displayed, the start button 38 is pressed to start the calibration (FIG. 5A).

  When calibration is started, first, an instruction mark 40 which is an operation display for calibration is displayed on the upper left of the touch panel display 14. The indication mark 40 stores the coordinates of the display position on the touch panel display 14 (FIG. 5 (b)).

  When the instruction mark 40 is displayed, a person performing calibration touches the center point of the instruction mark 40 with a finger or the like. When a finger or the like is touched, the touch panel display 14 reads a change in electric resistance value or the like, and stores the coordinates on the touch panel display 14 of the touched position as a designated position. The coordinates of the display position and the coordinates of the designated position are stored in the auxiliary storage device 30 or the like.

  Next, similarly, at the lower left of the touch panel display 14, an instruction mark 40, which is an operation display for calibration, is displayed. Moreover, the person performing calibration touches the center point of the instruction mark 40 with a finger or the like. Then, the coordinates of the display position and the coordinates of the designated position are stored in the auxiliary storage device 30 or the like. (Fig. 5 (c))

  These operations are performed for the position of the predetermined instruction mark 40. For example, the display of the instruction mark 40 and the instruction with the finger 20 or the like are repeated in the order of the upper right, lower right and center of the touch panel display 14 and the coordinates of the display position and the coordinates of the instruction position Is stored in The indication mark 40 is not limited to the five points on the left, right, upper and lower sides of the touch panel display 14 and the center, and can be displayed in any number according to the accuracy required for calibration.

  Next, calibration data 6 is generated from the coordinates of each stored display position and the coordinates of the designated position. For example, the CPU 12 obtains the difference between the coordinates of each display position and the coordinate of the designated position stored in the auxiliary storage device 30, and calculates the calibration data 6. More specifically, the amount of deviation from the coordinates of the display position of the coordinates of each designated position and the direction of deviation can be determined, and the average value can be used as the calibration data 6. Alternatively, the touch panel display 14 is divided into a plurality of areas, the indication mark 40 is displayed for each area, the deviation amount and deviation direction of the indication position at the coordinates of each display position are determined, and the calibration data 6 for each area is calculated. It can also be done. Then, the calculated calibration data 6 is stored in the non-volatile memory 8. Note that calibration can be performed at any time such as when the touch panel computer is first used, or when the indicated position deviates by continuing to use, etc., at the time of inspection before shipment of the touch panel computer, etc. You may go to

  As described above, calibration can be performed easily and simply by executing the calibration program 4 on the BIOS 10 and storing the generated calibration data 6 in the non-volatile memory 8.

  In the above description, the non-volatile memory 8 may be any type of storage device capable of holding stored data without supplying power, such as a flash memory.

  Further, the calibration program 4 is not limited to one operating on the BIOS, and may be configured to operate independently of the OS or the like.
