Abstract

PURPOSE:To directly designate the precise coordinates of an optional part of a graphic, etc., shown on a display screen by repeating the magnifying and touching operations of the optional part until a desired size of this part is obtained. CONSTITUTION:When a user looks at a graphic shown on a display device 3 and desires to observe the graphic more precisely, the user touches his/her desired part or a display area adjacent to the desired part and then instructs the display magnification. Thus the touching operation is detected by a touch detecting means 4 and the key data are outputted. Then a coordinate setting means 5 sets the display center position of the display data stored in a storage means 1 based on the key data. A display control means 2 reads again the display data out of the means 1, and a magnification instruction means 6 displays the graphic having its display center position is coincident with the center of a screen on the means 3 based on the magnification instructed by a magnification instruction means 6. Thus the display data on the graphic, etc., shown on the screen can be magnified and displayed in response to a touch key.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an input display device that allows coordinates to be specified by a touch operation on a display screen.

[Overview] The present invention enables direct specification of precise coordinates of any part of a drawing displayed on a display screen by repeating enlargement and touch operations until the desired size is reached. It was made possible to do so.

[Prior Art] Conventionally, in an input display device having a touch panel,
Using the transparent touch keys provided on the front of the display screen, as shown in FIG. 7, touch the desired display part 69 while looking at the screen, and read the data displayed on the touched display part. Since this is a device that is specified and entered by touching with a finger, the position resolution is lower than that of a normal digitizer, so it is necessary to select one item from among the dozens of items displayed, such as product name or customer name. It was used exclusively for.

[Problems to be Solved by the Invention] In the above-mentioned conventional input/display device using touch keys performed with a fingertip, etc., a drawing, etc. is displayed on the screen, and coordinates of a specific part of the drawing are input using the touch keys. I couldn't do it. For example, the wide-angle apex of a triangle displayed on the screen as shown in Figure 8 (a) and (b) (the part indicated by arrow 7 in the enlarged view of Figure 8 ('b) (the part surrounded by a broken line circle)) I couldn't stop myself from entering it. The reason for this is that the screen division area corresponding to the touch key requires a certain amount of area to correspond to the fingertip, etc. to be touched, and the display data exceeds the position resolution corresponding to the required area. This is because it is not possible to specify (the specified display portion within the screen split area that is smaller than the split area) by input.

If you do this, you cannot change the area of the touch key to a smaller size, so if you enlarge the display, that is, enlarge the specific part you are trying to specify, so that it corresponds to the area of the touch key. For example, it would be the same as increasing the position resolution of the touch keys by reducing the area of the touch keys while keeping the display size constant, and it would be possible to specify that specific part. think.

An object of the present invention is to enable display data such as figures displayed on a screen to be enlarged and displayed so as to correspond to touch keys.

[Means to solve the problem] The means of the present invention are as follows.

The display control means 2 (see the functional block diagram of the present invention in FIG. 1; the same applies hereinafter) controls the display based on the display data stored in the storage means 1 so that the display center position set by the coordinate setting means 5 faces west. Magnification indicating means 6 so that it is in the upper center
The image is enlarged to the magnification specified by and displayed on the display means 3.

The touch detection means 4 has a plurality of touch keys,
The display surface of the display means 3 is equally divided into a plurality of touch areas (display areas) corresponding to each touch key, and the display means 3
Detects a touch operation on a part of the display displayed on the screen.

Based on the touch operation detected by the touch detection means 4, the coordinate setting means 5 sets the display center position of the display data stored in the storage means 1 corresponding to the display position at which the touch operation was performed.

[For production] The operation of the means of the invention is as follows.

The display control means 2 reads display data such as figures stored in the storage means 1, and the user who displays the figures on the display means 3 based on the read display data If you look at a shape and need to observe further details or point out a point for your pointing device, touch the display area that contains the required part or the display area adjacent to that part; And when the display magnification magnification is instructed, the touch detection means 4
As a result, the touch operation is detected, key data corresponding to the touch operation is output, and the coordinate setting means 5 is notified of the touch operation. Then, by the coordinate setting means 5,
Based on the key data, the display center position of the display data stored in the storage means 1 corresponding to the screen display position corresponding to the key data is set. Then, the display control means 2 reads the display data from the storage means 1 again, and the figure whose display center position set by the coordinate setting means is at the center of the screen is displayed on the magnification specifying means. The image is displayed on the display means 3 based on the magnification indicated by 6.

With the above action, when you want to know the details of a certain part of the initially displayed figure, etc., or when you try to specify a certain point, by touching the display surface where that part or point is located, the touch The area you touched will become the center of the display screen, and the figure will be enlarged and displayed. In order to see more details, the user wants to zoom in further and touches the display area that he or she wants to enlarge, and the drawing is then enlarged and displayed with the touched area becoming the center of the display screen.

In this way, by enlarging the display of figures, etc., centering on the part specified by input, the complex display part that was initially displayed within one display area is enlarged, and due to this enlargement, the complex display part that was initially displayed within one display area is expanded. Complex display parts that were displayed within the display area are divided and displayed within each display area, so the positional resolution of the display area corresponding to the touch key is increased, and the display area with increased positional resolution can be touched. You can specify more detailed parts such as figures by specifying them. By repeating this designation and enlarged display, it is also possible to designate the initially designated portion of the figure at the coordinate position in units of display dots.

Therefore, display data such as figures displayed on the screen can be enlarged and displayed to correspond to the touch keys.

[Embodiment] An embodiment will be described below with reference to FIGS. 2 to 5.

FIG. 2 is a block diagram showing a system configuration of a coordinate input device according to an embodiment.

The multi-item keyboard 11 consists of a display section made of a liquid crystal display (LCD) and a transparent touch panel provided over the entire display surface of the display section.

The display section displays multiple items and various characters and figures, and the touch panel displays any pressing position f (Kl, K2,...KO2) on the screen of the display section at any resolution. It is a touch sensor that detects. In other words, when you press any position on the screen displayed by the display unit with your finger (evening/Sochi operation), that touch operation is detected by the touch panel, and the pressed position corresponding to the detected touch operation is detected. A signal is output from the multi-item keyboard 11 to the keyboard control device 12. The keyboard control device f12 converts the detection signal output from the multi-item keyboard 11 into a corresponding coordinate signal, and outputs the converted coordinate signal of the pressed position on the screen to the CPU13.

The CPU 13 controls the entire system according to a program stored in the ROM 14.

The CPU 13 includes the keyboard control device 12 and a ROM.
14 in addition to 1, RAM15, RAM16, and VRAM
17 are connected. Further, a display control device 18 is interposed and connected between the output terminal of the VRAM 17 and the input terminal of the multi-item keyboard 11.

The CPU 3 stores the X coordinate value kx and Y coordinate value ky on the screen of the pressed position output from the keyboard control device 12 in the coordinate information storage area 21 of the management table described later in the RAM 15. Further, calculations are performed based on the kx, ky and display magnification data d, bai, and the above k
Calculate the coordinate data dx, dy on the logical coordinates of the display data displayed at the position on the display screen specified by x, ky, and calculate the calculated coordinate data dx, dy and the magnification data d, ba 1Jfr :Write to the display information storage area 22 of the management table of the RAM 15, which will be described later.

The ROM 14 is made up of a ROM (read only memory), and stores programs for controlling the system and the like. In addition, the RAM 15 consists of RAM (random access memory), and is shown in FIG. 3(a).
(The management table shown in bl and consisting of a coordinate information storage area 21 and a display information storage area 22 is stored.

The RAM 16 draws, for example, graphic data to be displayed on the screen on logical coordinates corresponding to the graphic, for example, logical coordinates expressed with values of -32,768 to +32.768 on both the vertical axis y and the horizontal axis X. The data is stored based on the coordinate data on the logical coordinates of the figure.

Then, the CPU 13 reads the graphic data stored in the RAM 16 and determines the coordinate position on the logical coordinates of the read graphic data corresponding to the coordinate data kx, ky on the screen written in the management table of the RAM 15. Bit image data corresponding to the display center position and enlarged graphic display portion based on the magnification data also written in the management table is created, and the bit image data is written into the display memory 17. The display memory 17 is a bitmap memory that stores display data for one screen in a focus map format, and the display data written in the display memory 17 is read out at regular intervals by the display control device 18 and is read out by the multi-item keyboard 11. displayed on the display.

Next, the operation of the coordinate input device of one embodiment configured as described above is explained in FIGS. 4, 5 (a), (b), and (C).
This will be explained using FIGS. 6(a) and 6(b).

Outline of Operation First, a figure is initially displayed on the display screen. Specify the display magnification by touching a touch key that includes or is adjacent to a point in the figure you want to input coordinates.
The figure is enlarged at the specified display magnification and displayed on the screen with the touched part of the figure at the center of the screen. Each time the above touch operation and magnification specification are performed, the currently displayed figure is enlarged at the specified display magnification.1. The touched graphic part becomes the center of the screen and is displayed on the next screen.

If only a touch is made and no magnification is specified, the coordinate position on the logical coordinates of the touched display area is specified.

Next, FIG. 5 is a flowchart showing the operation of the CPU 13. Although not particularly shown, the user uses a separate input key to indicate whether or not to further enlarge the current screen display (whether coordinate input specification is not yet completed or not). Input is required, and the magnification for the next enlarged display is also specified by input.

The CPU 13 first stores the following information in the management table of the RAM 15.
Initialize kx and ky in the coordinate information storage area 21 to "0". Also, in the same management table, the display information storage area 22
Default values for dx and dy (e.g. r320J and r200
J) is initialized by setting rlJ to d and bai (step (hereinafter referred to as S) 1).

Next, the CPU 13 reads the display data from the RAM 16, creates graphic data (bit image data) of the same size specified by the initial value rLJ of d, bai, and
The logical coordinate position specified by each value of y (at the first screen display, the value is (320, 200) according to the above initial settings) is made to correspond to the center of the display screen, and the created graphic data is stored in the display memory 17. Write (S2).

The graphic data written in the display memory 17 is controlled by the display control device 18 to display, for example, two circles and one triangle as shown in FIG. 5(a) on the display section of the multi-item keyboard 11. Ru.

In this way, the first screen is displayed, so even if the user wants to input the coordinates of the point where the arc 23 and one side 24 of the triangle intersect in the same figure (al), Since this cannot be entered, in order to enlarge the figure in this part, specify this part and press 42 (
(indicated by diagonal lines). In this case, the input key to be operated may be any other touch key, 43°K2O or K51, which is close to the graphic part to be input.

The touch key manual operation is detected by the touch panel, and the key code corresponding to the touch position on the screen is transmitted to the keyboard control device 1 by the multi-item keyboard 11.
2, and the keyboard control device 12 converts the output key code into the corresponding coordinate information on the screen and displays it as C.
Output to PU13. Based on the coordinate information, the CPU 13 calculates an X coordinate value kx indicating the touched position on the screen;
The Y coordinate value ky is calculated and written to the coordinate information storage area 21 in the management table (S3).

The kx and ky mentioned above are 42 when the touch key 42 is operated on one touch key on the display screen 9 of the display section of the multi-item keyboard 11 as shown in FIG. 6 (bl).
These are the coordinates on the screen corresponding to the center position of .

Next, the CPU 13 writes kx, k which has been written above.
Based on the yO value, the value of 2 for the proportionality constant kl, and the values of d and bai, the coordinates on the logical coordinate displayed at the center of the display screen and the position on the screen where the touch operation was performed The distance between the two representing the positional relationship with the coordinates on the logical coordinates corresponding to The X coordinate and X coordinate indicating coordinates on the coordinate system are calculated, and the values of the calculated X coordinate and X coordinate are written in the display information area 22 in the management table (S4).

The proportionality constant kl, 2 is a constant that indicates the relationship between the display bits on the logical coordinates and the display bits on the display screen. If the display focus in the initial display area 8 on the logical coordinates shown in FIG. 6(a) is equal to the display via of the display screen 9 shown in FIG. 6(b), the value is "1", and the value on the display screen is This is a value determined in advance based on the density of the display element, etc. In this embodiment, for convenience, kl
, and 2 will be explained as "1".

In addition, the values of dx and dy in the initial display are as shown in the same figure (a).
The coordinates of the center point 8' in the initial display area 8 on the logical coordinates shown in are shown as r320J and r200J, respectively, as described above.

By the above operation, the coordinates on the logical coordinates displayed at the position touched by the user are input, but since the initially displayed figure is the same size, the input coordinates are displayed on the touch key. The coordinate of one of the more than 2,000 coordinate positions in the logical coordinates that corresponds to the coordinates on the display screen of one dot located at the center of more than 2,000 in the display area corresponding to be. In other words, it is close to the coordinates that the user attempted to specify (but not at the exact coordinates that the user attempted to specify).

In FIG. 5(a), when the user manually presses the touch key 42 and then manually presses the display magnification at "4", the key press signal is sent to the CPUI 3 via the keyboard control device 12. Be notified. CPU3
When detecting the key input signal of the display magnification by the user, it is determined that the numerical values indicating the display magnification written in d and baf were not large enough (S5). Based on the input magnification, a new magnification for the initial display is calculated, and the calculated new magnification is written into d and bai (S7).

Then, the process returns to step S2, reads the coordinate data in the RAM 16, and based on the read coordinate data,
Create graphic data with the magnification specified by d and bai, and make the logical coordinate position specified by dx and dy created in step S4 and written in the display information area 21 correspond to the center of the screen of the display unit. , writes the graphic data created above into the display memory 17.

Then, as explained above, this display memo IJ17
Based on the graphic data written in the display control bag W1
8 performs display control, and a figure as shown in FIG.

Since the magnification input by the user in Figure (a) is "4", the figure shown in Figure (a) is multiplied by 4 in length and width (its area is 16 times), and it is shown in Figure (b). It will be displayed as shown. The graphical portion corresponding to the item key 42 manually pressed by the user in FIG. 12(a) is enlarged four times as described above and corresponds to the left hatched area 25 in the center of the screen in FIG. 2(b).

In this way, the bits indicating more than 2,000 logical coordinate positions, which initially corresponded to one touch key, now correspond to 16 touch keys.

That is, the number of bits of the logical coordinate position corresponding to one touch key is 2000/16, which is approximately 125 bits. However, even if the user wants to input the coordinates of the point where the right-hand arc 23 intersects the straight line 24 of the two arcs shown in FIG. Since input is not possible in this state, in order to further enlarge the figure in this part, in step S3, the touch key 62 (indicated by diagonal lines on the right) is pressed.

In this case as well, the input key to be operated is 61°K69.
It may be either K2O.

By the above-mentioned key manual, the CPUI 3 performs the above-mentioned step S
3. S4. S5. Repeat S7 and S2 to create the image shown in Figure 5 (
Display the enlarged chart as shown in C).

The figure in the display area corresponding to the touch key 62 in the same figure (b) is enlarged four times and is shown in the same figure (c).
This corresponds to the left hatched area 25 in the center of the display screen. Furthermore, the point at which the user attempted to input coordinates, that is, the intersection of the arc 23 and the straight line 24, is also enlarged and displayed within the display area corresponding to touch key 67.

Here, the user can input the desired coordinates by inputting 67 to the item key.

When the user performs an input operation of 67 on the item key, the CPU 3 again performs the processing in steps S3 and S4, and then determines the user's magnification input in step S5. As described above, since the user has completed the desired coordinate input operation, the user does not input the magnification factor, but manually inputs the key to instruct the user to finish. The CPU 13 determines that the coordinate input has been completed by manual input of the key, and the coordinate position specified by dx and dy written in the display information area 21 in the immediately preceding step S4 is the coordinate on the logical coordinate input and specified by the user. It is determined that

The determined dx and dy data are output for use in other processing as necessary.

As described above, when the touch key Ki is operated, the display position of the portion corresponding to the touch key Ki is newly set to the center of the screen, and the display is enlarged at the specified enlargement ratio. This enlarged display can be repeated until the necessary coordinates can be directly input. Therefore, after displaying the actual figure on the screen, you can specify and input precise coordinates by simply performing a simple manual key operation (touch operation). Corrections can also be made.

The coordinate input device described above can also be used as a pointing device, and various applications are possible.

In the above embodiment, a separately provided input key is used to enter the magnification data and the end instruction. , the item data representing those instructions is "2x", "4x",
It is also possible to display "End" or the like and allow the user to select from among the item data and perform touch input.

Further, although the display area corresponding to each touch key is square, it may be rectangular.

[Effects of the Invention] According to the present invention, since the screen is enlarged and the desired touch position is displayed at the center of the screen, precise coordinates can be input easily.
