Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a resistive touch panel, and more particularly, to a resistive touch panel capable of assigning an arbitrary process to simultaneous pressing of a plurality of target areas (software keys) and data processing. Related to the device.

[0002]

2. Description of the Related Art A resistive touch panel comprises a position detecting panel having a pair of transparent resistive films disposed opposite to each other, and a display device disposed below a position detecting section. The display device is a data processing device (computer)
In accordance with the instruction, an area to be pressed such as an operation key (including an operation button, an icon, and the like) for inputting data and instructions is displayed together with image information and character information.

When a user touches a displayed key or the like (presses an operation surface) while viewing a screen through a position detection panel, the position where the position detection panel is pressed is detected, and a data processing device (computer) is detected. Notify. The data processing device determines a touched key or the like from the notified position, and executes an input and a process corresponding to a user operation.

[0004]

The touch panel must simultaneously display the information originally intended to be transmitted to the user and the input keys on the same screen. Therefore, the area of the information display area on the screen and the area of the input area have a trade-off relationship, and the size of any area is limited.

In order to enable various inputs with a small number of keys, a specific key such as a shift key and other keys must be simultaneously pressed on a resistive touch panel as in the shift function of a normal keyboard. Thus, it is conceivable that an input different from the normal time is performed.

However, due to the structure of the resistive touch panel, when a plurality of positions are simultaneously pressed, the positions of the centers of gravity of the plurality of pressed positions are determined by one instead of individually detecting the pressed positions. It is detected as a pressed position. For this reason, a process different from the user's intention may be performed. Therefore, conventionally, only one input is assigned to each key for processing.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described circumstances, and uses a resistive touch panel and a touch panel that can execute a predetermined process by assigning an arbitrary process to simultaneous pressing of a plurality of pressing target areas. It is an object of the present invention to provide a data processing system. It is another object of the present invention to provide a resistive touch panel capable of effectively utilizing a display area and a data processing system using the touch panel.

[0008]

In order to achieve the above object, a data processing apparatus having a resistive touch panel according to a first aspect of the present invention comprises n data processing devices each having a predetermined process assigned thereto (where n is a predetermined number). Display means for displaying a (two or more natural number) pressing target area on the display screen; and a pair of flexible resistive films arranged on the display screen of the display means and arranged to face each other. A pressing position, a panel in which the resistive film is deformed and in contact with each other, a pressing position detecting means for detecting a contact position of a pair of resistive films of the panel, and a pressing position detected by the pressing position detecting means, When located in any of the plurality of pressing target areas on the display screen, the processing assigned to the pressing target area is executed, and when the position is the position of the center of gravity of the plurality of pressing target areas, Determined Processing means for executing the constant process,
Comprising, when a plurality of pressing target areas are pressed simultaneously,
It is characterized in that processing other than the processing assigned to each pressing target area can be executed.

In the case of a resistive touch panel, when a plurality of locations are pressed, the coordinates of the position of the center of gravity of those locations are detected, and the pressed locations cannot be discriminated individually. However, according to the configuration of the present invention, when the position of the center of gravity is detected because a plurality of positions are pressed, processing assigned to the detected position of the center of gravity, for example, input of data or a command is performed. Therefore, an arbitrary process can be allocated and executed not only for the process allocated to each pressing region but also for the simultaneous pressing of a plurality of pressing regions. Therefore, for example, input processing using a shift key or a control key can be performed in the same manner as a normal keyboard.

The display means includes, for example, a panel-shaped display device, and the pair of resistive films are made of a transparent film. Further, for example, according to the content of the data processing to be executed, the processing unit causes the display device to display n pressing target areas to which a predetermined process is assigned, and the pressing unit detects the n pressing target regions. When the pressed position is located within any of the plurality of pressed target regions on the display screen, it is determined that the pressed target region has been pressed, and the process assigned to the pressed target region is performed. Run,
When the positions of the centers of gravity of the plurality of pressing target areas are determined, it is determined that the plurality of pressing areas are pressed simultaneously, and a predetermined process is performed.

[0011] The processing means arranges each pressing target area so as to avoid a center of gravity of the pressed pressing target area when a plurality of other pressing target areas are simultaneously pressed. If the position of the center of gravity of the plurality of pressing target areas matches an arbitrary pressing area, when the position is detected, it becomes impossible to identify whether the plurality of pressing positions are pressed or the positions are pressed alone. . According to this configuration, since the arrangement of the pressing target region is devised, such a situation can be prevented.

[0012] The processing means displays an image different from the pressing target area at the position of the center of gravity of the plurality of pressing target areas arranged on the display screen. No other pressing target area can be arranged at the position of the center of gravity of the plurality of pressing target areas. In this case, by using these areas as areas for displaying a message to the operator as a result of data processing, the display area can be used effectively.

In order to achieve the above object, a resistive touch panel according to a second aspect of the present invention includes a pair of flexible resistive films which are arranged to face each other and come into contact with each other at a pressing position. A panel in which a plurality of predetermined pressing target areas are formed, a pressing position detecting unit that detects a contact position of a pair of resistive films of the panel, and a pressing position detected by the pressing position detecting unit. If it is located in any of the plurality of pressing target areas, it is determined that the pressing target area has been pressed, and if it is the position of the center of gravity of the predetermined plurality of pressing target areas, And a determining means for determining that the pressing target area has been pressed.

According to this configuration, it is possible to determine that a plurality of target areas are pressed simultaneously, even though the touch panel is a resistive touch panel.

In order to achieve the above object, an input device according to a third aspect of the present invention provides a plurality of input devices for inputting different instructions on a display screen by using a switch key and a combination of the switch keys. Display means for displaying input keys, a transmissive operation surface stacked on the display means, a position detection panel for detecting the position of the center of gravity of one or more pressed positions, and According to the position information, when the position of any input key is detected, the information assigned to that input key is input, and when the position of the center of gravity between the switch key and any input key is detected, the switch key and And input means for inputting information allocated to the combination with the input key.

According to the structure of the present invention, when a plurality of places are simultaneously pressed, the position of the center of gravity is detected, but the plurality of pressed positions are determined, and a combination of the pressed areas is determined. , For example, data and commands can be input.

[0017]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a resistive touch panel system according to an embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the resistive touch panel system according to this embodiment includes a resistive position detecting panel 1, a display device 2, and a data processing unit 3. The position detection panel 1 includes a transparent operation surface 1a, and the display device 2 includes a display screen 2a, and the display device 2 is stacked so that the operation surface 1a is positioned on the display screen 2a. The data processing unit 3 includes the position detection panel 1 and the display device 2
And receives an input from the position detection panel 1,
An image signal (video signal) is supplied to the display device 2.

The position detecting panel 1 is, as shown in FIG.
It comprises a position detection unit 101 and a signal processing unit 102. As shown in FIG. 3, the position detection unit 101 includes first and second resistance films 11 and 12 arranged in parallel at a distance from each other.
It includes transistors Tr1 to Tr4. The first and second resistance films 11 and 12 are made of a flexible transparent resistance film such as an ITO film. A transparent protective film for protecting the first resistive film 11 is disposed on the first resistive film 11, and forms an operation surface to be pressed by the user.
When the user touches the transparent protective film, as shown in FIG. 4, the transparent protective film and the first resistive film 11 are deformed, and the first resistive film 11 contacts the second resistive film 12.

Electrodes Y0 and Y1 are formed in the longitudinal direction on the upper side and the lower side of the first resistance film 11 in FIG. The electrodes X0 and X1 are provided on the left side and right side of the second resistance film 12, respectively.
Are formed so as to be orthogonal to the electrodes Y0 and Y1.
The electrode X0 is connected to the power supply terminal to which the voltage VCC is applied via the transistor Tr1, and the electrode X1 is connected to the transistor T1.
It is grounded via r3 and connected to an A / D converter 21 of the signal processor 102, which will be described later. The electrode Y0 is connected to the supply line of the voltage VCC via the transistor Tr2, and the electrode Y1 is grounded via the transistor Tr4 and is connected to an A / D converter 21 of the signal processing unit 102 which will be described later.

The transistors Tr1 and Tr3 and the transistors Tr2 and Tr4 are controlled by a later-described coordinate detection circuit 22 of the signal processing unit 102, and are alternately turned on / off at a predetermined timing.

When detecting the X coordinate of the pressed position on the operation surface 1a, the transistors Tr1 and Tr3 shown in FIG.
The transistors Tr2 and Tr4 are turned off. This allows
The voltage VCC is applied to the electrode X0, and the electrode X1 is grounded.

In this state, when an arbitrary point on the operation surface 1a, for example, point A is pressed, the first resistive film 11 and the second resistive film 12 contact at point A. The voltage V at point A at this time
AX becomes a value shown in Expression 1 when the input impedance of the A / D converter 21 is sufficiently large.

[0023]

VAX = VCC * XA / LX where LX: value proportional to the distance between electrode X0 and electrode X1 XA: value proportional to the distance between electrode X0 and point A

The X coordinate XA of the point A on the touch panel can be obtained from Expression 2 obtained by transforming Expression 1.

[0025]

XA = (VAX / Vcc) * LX

On the other hand, when detecting the Y coordinate, the transistors Tr1 and Tr3 shown in FIG.
2. Turn on Tr4. Thereby, the voltage V is applied to the electrode Y0.
CC is applied and the electrode Y1 is grounded.

At this time, the voltage VAY at the point A is calculated assuming that the input impedance of the A / D converter 21 is sufficiently large.
The value shown in Expression 3 is obtained.

[0028]

VAY = VCC * YA / LY where LY is a value proportional to the distance between electrode Y0 and electrode X1 YA: a value proportional to the distance between electrode Y0 and point A

The Y coordinate YA of the pressed position A on the operation surface 1a can be obtained from the expression 4 obtained by modifying the expression 3.

[0030]

## EQU4 ## YA = (VAY / VCC) * LY

In this coordinate detection method, for example, as shown in FIG. 3, when point A (coordinates (XA, YA)) and point B (coordinates (XB, YB)) are pressed simultaneously, the voltage at point A And the average voltage of the voltage at point B is detected. For this reason,
In this coordinate detection method, when both points A and B are pressed simultaneously, the coordinates of point C, which is the position of the center of gravity of points A and B, are detected.

The signal processing unit 102 shown in FIG. 1 includes an A / D conversion unit 21 and a coordinate detection circuit 22.

The voltages of the electrodes X1 and Y1 are selectively supplied to the A / D converter 21 according to the on / off states of the transistors Tr1 to Tr4. The A / D converter 21 performs A / D (analog-digital) conversion of the supplied voltage, and supplies the converted digital value to the coordinate detection circuit 22.

The coordinate detection circuit 22 controls the entire operation of the position detection panel 1. For example, transistors Tr1 and T
R3 and the transistors Tr2 and TR4 are alternately turned on / off at a predetermined cycle to obtain digital values of the voltages of the electrodes X1 and Y1. The coordinate detection circuit 22 calculates the coordinates (X, Y) of the pressed point from the obtained digital value, and supplies the calculated coordinates (X, Y) to the data processing unit 3.

The display device 2 comprises a panel-shaped display device such as a liquid crystal display device. The display device 2 outputs various images according to the image signals supplied from the data processing unit 3,
For example, a text or image as information to be transmitted to the user, or a pressing target area (an image of a button, key, icon, switch, or the like) for allowing the user to input data or an instruction is displayed on the display screen.

As shown in FIG. 2, the data processing unit 3 includes a coordinate input unit 31, a form ROM 32, a control / processing unit
3, RAM 34, display control unit 35, auxiliary storage device 36,
And so on. The coordinate input unit 31 takes in the coordinate data supplied from the coordinate detection circuit 22 and
To supply.

The form ROM 32 stores various input forms to be displayed on the display screen 2a of the display device 2. FIG. 5 shows an example of the input form stored in the form ROM 32. This input form is a form for inputting alphabets and numbers. As shown in the figure, this input form has a configuration similar to a normal keyboard, and includes a character key of 26 letters of the alphabet, a numeric keypad of numbers from 0 to 9, and a shift key for designating upper case and lower case. Prepare.

The screen is configured so that each key on the form is not located at the center of gravity of the position of the shift key and any other key. For example, as shown in FIG. 6, the center of gravity of the shift key and the “b” key is substantially
11B, each key is arranged at this position so that no other keys are arranged. Similarly, the other keys are arranged so as to avoid the center of gravity of the other key and the shift key. These areas are used as message display areas (message superimposition areas) for displaying messages to the user and the like.

The position of each key on the input form (upper and lower limits of x coordinate and upper and lower limits of y coordinate)
Are stored in the form ROM 32 as a first group of tables for each form, as shown in FIG. For example,
As shown in FIG. 6, when the X coordinate is XaL to XaU and Y
The range of coordinates from YaL to YaU is the area of the “a” key. Therefore, as shown in FIG. 7, in the form ROM 32, the X coordinate is XaL ≦ x ≦ XaU and the Y coordinate is YaL ≦ y ≦ Y in association with the identification code of the input form.
It is set that the range of aU corresponds to lowercase "a".

In the form ROM 32, coordinates of an area of a predetermined size centered on the center of gravity of each character key and shift key are registered as coordinate data of a second group of areas corresponding to capital letters. For example, as shown in FIG.
A capital "B" key is virtually allocated to an area 111B of a predetermined size centered on the center of gravity of the "b" key and the shift key. The range XBL to XBU of the X coordinate and the range YBL to YBU of the Y coordinate of the area 111B are defined as areas corresponding to the capital letter "B".
2 in the second group table. Similarly, capital letters corresponding to areas of a predetermined size centered on the center of gravity of the shift key and each character key are assigned to other alphabets, and the coordinates of each area are stored in the form ROM 32.
Registered in.

The control / processing section 33 is constituted by a microprocessor or the like, reads a program stored in the auxiliary storage device 36 into a RAM (main memory) 34, executes the program, and executes various data processing defined by the program. Execute. In the course of this data processing, when it becomes necessary to input data or instructions from the user, the control / processing unit 33
The input form is read from the form RAM 32 as appropriate, combined with a message or the like as appropriate, and displayed on the display device 2. Then, it receives the position data supplied from the position detection panel 1, determines which key has been pressed, and reflects it in the subsequent processing.

The RAM 34 functions as a main memory and a work memory of the control / processing unit 33. Display control unit 35
Supplies the image data to be displayed to the display device 2 according to the instruction of the control / processing unit 33. The auxiliary storage device 36
The control / processing unit 33 stores a program to be executed by a hard disk device, a DVD device, and the like.

Next, the operation of the data processing system including the touch panel having the above configuration will be described. Data processing unit 3
When an arbitrary program stored in the auxiliary storage device 36 or the like is activated, the computer executes a process defined by the program (general processing executed by a computer, such as information processing, data processing, and control processing). Data processing unit 3
Displays an input screen on the display device 2 when data input or instruction from a user (operator) is required in the process of processing. Here, a case will be described as an example in which a user is required to input alphabets and numerals for inputting a password.

The control / processing unit 33 of the data processing unit 3 converts an input form shown in FIG. 5 for inputting alphabets and numerals for inputting a password into a form ROM.
Read from 32. The control / processing unit 33 sets a window or the like for displaying a message to input a password or input data in an empty area (an area where a virtual key for a capital letter is allocated; a message display area) of the input form. A form as shown in FIG. 8 is formed by synthesis, and displayed on the display device 2 via the display control unit 35.

As described above, this screen is provided with a character key of 26 alphabets, a numeric keypad of numbers 0 to 9, and a shift key for designating uppercase and lowercase letters. It is arranged not to be located at the center of gravity of any key position.

The input form displayed on the display screen 2a can be observed through the transparent operation surface 1a. In this state, when the operator touches the “a” key, the first resistive film 1
The first and second resistive films 12 contact at that position as shown in FIG. The coordinate detection circuit 22 includes transistors Tr1,
TR3 and the transistors Tr2 and TR4 are alternately turned on / off at a predetermined cycle.
The voltage of the electrode X1 is A / D converted at the timing when the transistors Tr1 and TR3 are turned on, and the digital value
Is output, and the voltage of the electrode Y1 is A / D converted at the timing when the transistors Tr2 and TR4 are turned on, and a digital value DY is output.

The coordinate detection circuit 22 calculates the coordinates (X, Y) of the pressed position from the supplied digital values DX and DY in accordance with Equation 5 similar to Equations 2 and 4 described above.

[0048]

X = (DX / DVCC) * LX Y = (DY / DVCC) * LY where LX: maximum value of X coordinate, LY: maximum value of Y coordinate, DVCC: digital value of voltage VCC

The coordinates (X, Y) calculated by the coordinate detection circuit 22 are supplied to the data processing unit 3.

When the coordinate data is supplied, the data processing section 3 starts the processing shown in the flowchart of FIG. 9, and first, the supplied coordinates (X, Y) are stored in the form ROM 32.
It is determined whether or not any of the coordinate ranges of the first group registered in (1) is entered (step S11). In this example, since the “a” key is pressed, the control / processing unit 33 determines that the supplied coordinates (x, y) are XaL ≦ x ≦ XaU, YaL ≦ y ≦ YaU
Is determined as YES, and the process proceeds to step S12.

In step S12, the control / processing unit 3
No. 3 determines that the key at the determined position is pressed alone and performs a process of inputting the character or number. In this example, it is determined that the “a” key is pressed alone and a lowercase “a” is input. Then, processing corresponding to the input content, for example, inputting "a" to the input buffer and displaying "a" in the input window is performed.

Next, while the operator presses the shift key,
Suppose the "b" key is pressed. Also in this case, the voltage value corresponding to the pressed position is notified to the coordinate detection circuit 22. However, in this case, since the first resistive thin film 11 and the second resistive thin film 12 are in contact at the position of the shift key and the position of the “b” key, the voltage supplied to the A / D converter 21 is The voltage value corresponds to the X coordinate and the Y coordinate of the position of the center of gravity of both keys. For this reason, the coordinate detection circuit 22 is provided in the area 1 shown in FIG.
The coordinates corresponding to 11B are detected and supplied to the data processing unit 3.

The control / processing unit 33 of the data processing unit 3 determines in step S11 of FIG.
Determine that it does not belong to any of the group coordinate ranges,
It is determined whether it belongs to any of the coordinate ranges of the second group (step S13). In this example, since the shift key and the “b” key are pressed, the control / processing unit 33
Determines that the supplied coordinates (x, y) correspond to XBL ≦ x ≦ XBU and YBL ≦ y ≦ YBU in the coordinate range of the second group, that is, YES.

According to the result of this determination, the control / processing unit 33
Are keys associated with the detected center of gravity,
That is, it is determined that the shift key and the "b" key have been pressed at the same time, and the process assigned to the combination of both keys is performed (step S14). In this example, the capital letter "B"
Is input to the input buffer, and displayed in the input window as necessary. If it is determined as NO in step S13, other processing is executed (step S13).
15).

As described above, according to the data processing apparatus of this embodiment, if the pressed position detected by the position detection panel 1 is inside any of the key areas, it is determined that the input key is pressed alone. Judgment is performed, and the processing assigned to the key (in the above example, input of lower case letters or numbers) is performed.

On the other hand, if the position detected by the position detection panel 1 is not located inside any of the key areas, the detected position is a predetermined size centered on the center of gravity of the shift key and the input key. It is determined whether or not it is located in the area. If it is determined that the key is located within the area, it is determined that both the shift key and the input key have been pressed, and the processing assigned when both keys are pressed simultaneously (in the above example, uppercase letters are used). Input).
Therefore, an input can be made by a combination of a plurality of keys as in a normal keyboard. For this reason, these characters can be input with a key arrangement in which a key for uppercase input and a key for lowercase input are separately provided. Moreover,
It is possible to operate with the same feeling as a normal keyboard, and the burden on the user, such as familiarity, is reduced.

In the case of the input form shown in FIG. 5, for example, if another key is arranged at the position of the center of gravity of the shift key and the "b" key, if the combination of the shift key and the "b" key is input, It cannot be identified whether the key at that position has been input alone. However, in the input form of this embodiment, since each key is previously arranged so as to avoid the position of the center of gravity between the shift key and the other keys, no detection error occurs. Moreover, in these areas (areas where keys are virtually assigned), messages to the user and the results of data processing are displayed.
These areas are not wasted.

The resistive touch panel of the present invention is not limited to this embodiment, but can be arbitrarily modified and applied. For example, in the above description, an example is shown in which a shift key and a character or numeric key are arranged, but the type of the key is arbitrary. For example, switching keys such as a shift key, a control key, and an ALT key and function keys f1 to f
10 may be arranged so that various functions, functions, macros, and the like can be input and designated according to the combination of both keys. Alternatively, an arbitrary character or processing may be assigned to simultaneous pressing of three or more keys, and the processing may be executed when the coordinates of the center of gravity of those keys are detected.

The target of the pressing operation is not limited to the key, and there is no problem in an arbitrary pressing area such as a button or an icon. In addition, the configuration of the position detection panel 1 is a resistive film-film type, or a glass-glass type, or
It can be applied to glass-film type.

In the above description, a liquid crystal display device is used as the display device 2. However, a display device other than the liquid crystal display device, for example, a CRT can be used. Further, although the input form is stored in the form ROM 32, the input form may be stored in the auxiliary storage device 36 or may be generated as needed.

[0061]

As described above, according to the present invention,
When a plurality of keys are operated simultaneously, unique processing can be assigned.
