Description

[Detailed Description of the Invention] [Table of Contents] Overview Industrial Field of Use Conventional Technology Problems to be Solved by the Invention Means for Solving the Problems (Figure 1) Working Examples (1) Examples (Fig. 2, Fig. 3) (2) Operation of the embodiment (Fig. 4) Effects of the invention [Summary] The present invention allows the user to touch the touch panel with his or her finger when inputting data within an area set by the touch panel. This allows information to be input by moving into a preset area while touching the button.

[Industrial application field]

The present invention relates to a touch panel input method, and in particular, even if a finger first touches an area outside of a preset area on the touch panel, information can be input even if the finger moves to the preset area while touching the touch panel. , and also relates to a system that prevents information from being input even if the user moves to the settings area again while touching the touch panel after inputting the information.

One of the data input means in a data processing device is a touch panel input method. In this system, a touch panel, which is a transparent coordinate detector, is placed above a display surface such as a CRT. Meritsuku, Aiueo 50 sounds) are input.

[Conventional technology]

The conventional touch panel input method is to look at an illustration of the framed letters (numbers) of the key displayed on the CRT screen behind the touch panel, and touch the key part on the illustration with your finger from above the touch panel to input the coordinate data. data such as characters will be input based on the input.

[Problem that the invention seeks to solve]

By the way, the conventional touch panel input method is
Only the coordinates where the finger touched the touch panel for the first time were checked to see if they were within a preset area to input information.

Therefore, if the finger first touches outside the preset area on the touch panel, there is a drawback that information cannot be input even if the finger moves within the preset area while touching the touch panel. . Therefore, when many small frames are displayed on the display screen, it takes time for an inexperienced person to input the necessary information. In addition, in order to improve these shortcomings,
If you simply enter information based on whether the coordinates your finger touches are inside or outside a preset area,
If your finger moves near the boundary of the area,
There is a drawback that the information intended by the information inputter may be input multiple times.

An object of the present invention is to provide a touch panel input method that solves these problems.

[Means for solving problems]

In order to achieve the above object, in the present invention, as shown in FIG. is held in the effective area management table 6, and the main controller 5 compares the touched positions on the touch panel 2. The touch position of the finger on the touch panel 2 is transmitted from the touch panel control section 3, and the setting area for the display section 1 is displayed on the display section 1 by the CRT control section 4, which can be viewed via the transparent touch panel 2. be able to.

[Effect]

Now, the information inputter is pressing the first button on touch panel 2.
When you first touch point T shown in FIG. '' is entered, and unless the finger is removed from the touch panel 2 thereafter, information input will not be enabled even if the finger is moved in or out of the setting area including this "2". Therefore, the information inputter can input the information of the setting area touched first only once.

〔Example〕

(1) Configuration of Embodiment The configuration of an embodiment of the present invention will be explained based on FIGS. 2 and 3.

FIG. 2 is a configuration diagram of an embodiment of the present invention, and FIG. 3 is an explanatory diagram of its effective area management table.

In the figure, the same reference numerals as in FIG. 1 indicate the same parts.

The touch panel control section 3 detects and outputs the coordinates of the information input person's finger when it touches the touch panel, and also outputs the touch state indicating that the finger has touched the touch panel and that the finger has left the touch panel.

The CRT control unit 4 controls the display state of the display unit 1 made of a CRT, and is a setting area for characters (including other input items such as numbers, symbols, etc.) where illustrations are first displayed and information is input. Performs controls such as bling or displaying in a different color or brightness.

The main control unit 5 performs control to input the information of the setting area first touched by the finger only once while the finger is in contact, and the reading unit 10 reads the key code information from the effective area management table. , a touch state receiving section 11 that receives a touch state signal indicating whether or not the finger is in contact with the touch panel from the touch panel control section 3 and outputs the state; It comprehensively controls the comparison unit 12 that determines the setting area, the flag 13, the illustration control unit 14 that performs control to display the setting area into which information has been input in a bling display or in a color different from other setting areas, and the main control unit 5. A control unit 15 and the like are provided.

The effective area management table 6 shows the setting area of each key, that is, the character frame in the key illustration displayed on the display unit 1.
As shown in Figure a, it is composed of a key number area C0 indicating the total number of key illustrations to be displayed, and key code areas C ₁ , C ₂ . . . indicated by the key illustrations. The example in Figure 3a shows a key illustration showing the 10 numbers 0 to 9 shown in Figure 1b, and 16 notation "0A" indicating 10 is written in the key number area. There is. Key code area C ₁ indicates the first number 0, and if the setting area for that 0 is shown in Figure 3b, the maximum and minimum values of the X and Y coordinates indicating the range of the setting area are The key code “30” is filled out and indicated by the setting area.
(indicates 0 in ASCII display) is written.
The same thing is written in the key code area _C2 ....

(2) Operation of the Embodiment The operation of the configuration of the embodiment of the present invention shown in FIG. 2 will be explained based on the flowchart in FIG. 4.

Prior to information input, the control unit 15 reads out the information from the reading unit 10.
Key from effective area management table 6 for
The illustration is read out and displayed on the display section 1 via the CRT control section 4. Therefore,
On the display section 1, a key illustration shown in FIG. 1b is displayed. At this time, the touch state receiving section 11 sets the flag 13 to a reset state,
Since the control unit 15 controls the comparison unit 12 to perform a comparison operation, information input is enabled in this state, that is, when the finger of the information inputter is touching the key setting area, the information is input. is in a state of

When the information input person's finger touches the touch panel 2 in a state where such information input is enabled, the touch panel control section 3 detects the touch coordinates and sends them to the comparison section 12.

The touch panel control section 3 reports the touch of the finger to the touch state receiving section 11, and the touch state receiving section 11 reports this to the control section 15. The control unit 15 thereby causes the reading unit 10 to read the effective area management table 6 and output it to the comparison unit 12. At this time, the reading unit 10 reads the key number area _C0 of the effective area management table 6, recognizes the size of the required key code area, and reads out the necessary part. The comparison unit 12 compares the coordinate information transmitted from the touch panel control unit 3 with the set area indicated by the coordinate information read from the effective area management table 6. At this time, the first point touched is, for example, point T shown in FIG. Recognize that the coordinates you are touching are within the valid area.

At this time, as shown above, since the flag 13 has been reset and this indicates that the information input is valid, the comparator 1
2 outputs a key code 30 (indicates 0 in ASCII display) for the effective area, and is held in an information input receiving section (not shown).

The output information corresponding to this effective area is also transmitted to the set terminal S of the flag 13 and the illustration control section 14. As a result, the flag 13 is set and an instruction is given to the comparator 12 to invalidate the information input, and even if the finger moves outside the valid area while in the touch state and moves back into the valid area, the corresponding matching information will be displayed. Outputs and suppresses input processing. In addition, the illustration control section 14
The output information corresponding to the valid area transmitted to the CRT controller 4 causes the CRT control unit 4 to perform processing to display the valid area part, in this example, the 0 area part, in bling or in a different color. This will allow you to confirm the data you have entered.

By the way, the information inputter needs to take his/her finger off the touch panel 2 in order to input data next. Therefore, the person entering the information must use the Touch Panel 2.
If the finger is further removed, the touch panel control section 3 detects this and notifies the touch state receiving section 11.
As a result, the touch state receiving section 11 is controlled by the control section 15.
The control unit 1 reports that the finger has been released.
5 causes the illustration control unit 14 to erase the previously displayed information input display state by bling or the like. Furthermore, the touch state receiving section 11 resets the flag 13 to enable information input again, making the next information input possible.

In addition, when the finger that once touched an effective area moves to another effective area while touching the touch panel or enters and exits the same effective area again, the comparison unit 12 reports this to the control unit 15. The control unit 15 erases the information input display previously displayed by bling or the like to indicate that the information has not been input.

By the way, in the above explanation, an example of numbers as key illustrations was explained, but the present invention is of course not limited to this, and can be similarly applied to inputting symbols, 50 syllabary characters, and other characters. be. Further, the display unit is not limited to CRT, and other display units can also be used. Further, as the touch means, not only a finger but also an appropriate means such as a stick for inputting coordinates can be used.

〔Effect of the invention〕

According to the present invention, an information inputter can input information even when he or she first touches outside the effective area of the touch panel and then moves his or her finger or stick to the effective area. Even if the user moves multiple times in succession, information is input only the first time, so there is no possibility that multiple pieces of data will be input by mistake. Therefore, 50
Even when a large number of characters are displayed in a small effective area on a display screen, such as sounds, touch input can be performed reliably.
