Abstract

PROBLEM TO BE SOLVED: To lower occurrence frequency of erroneous input of a touch panel input device. SOLUTION: When an object indicating a selection item is displayed on a display section 11, a user looks at the object via a transparent panel 12a of a coordinates input section 12 and touches the panel 12 for inputting input coordinates of the object to be selected. A coordinates comparison section 14 finds normal coordinates of the object stored at that time in a storage section 13 and a distance d from input coordinates S12. An object effective coordinate correction section 15 corrects and rewrites the normal coordinates of the object on the basis of the distance d. Thereby a parallax of the user is corrected and afterward the occurrence frequency of erroneous input is lowered.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a touch panel input device and the like in which a light-transmitting coordinate input unit is arranged on the front side of a display unit, and selection items can be selected by touching the coordinate input unit. It is.

[0002]

2. Description of the Related Art FIG. 9 is a block diagram showing a conventional touch panel input device. A touch panel input device used as an input unit of a product using a computer includes, when an image is displayed on a screen, a coordinate input unit 2 including a light-transmitting panel arranged on the front surface of the screen of the display unit 1. ing.

[0003] An icon (hereinafter referred to as an object) schematically representing a button or the like indicating a selection item is displayed on the display unit 1.
3 is displayed in an arbitrary number. This object is for allowing the user to select a selection item. Coordinate input unit 2
, Transparent switches are arranged in a grid pattern, and the coordinates of the position where the user touches the coordinate input unit 2 are input to the computer. The computer estimates a selection item selected by the user from the input coordinates.

However, if the user looks at the center of the object 3 of the display unit 1 from a position shifted by an angle θ in the X direction without looking at the screen of the display unit 1 from the front which should be viewed, the user's eyes The position at which the straight line connecting the object and the center of the object 3 passes through the coordinate input unit 2 is different from that when viewed from the front. This is the parallax. Even if the user touches the coordinate input unit 2 to press the center of the object 3 when viewed obliquely from the angle θ,
The position is shifted from the original position to be touched by the distance δ. Therefore, due to the parallax, the adjacent object 3
An erroneous input such as selection of a password has often occurred.

As a technique for preventing such an erroneous input caused by parallax, for example, Japanese Patent Laid-Open No. 6-13109 is disclosed.
No. 4 and JP-A-5-73755. Japanese Patent Application Laid-Open No. H6-131094 discloses a technique for preventing an erroneous input due to parallax by increasing the size of an object 3 and an interval between adjacent objects, and counting the number of times multiple objects are pressed at the same time. A method of changing a determination area of coordinates for determining that the object 3 has been selected when the object 3 is exceeded is shown. Further, Japanese Patent Application Laid-Open No. 5-73755 discloses a device that makes the angle of a screen movable according to the parallax and eliminates the parallax itself.

[0006]

However, the conventional touch panel input device has the following problems.
Changing the size of the object 3 or widening the interval between adjacent objects 3 to prevent erroneous input due to parallax can be performed only when the number of objects 3 to be displayed simultaneously is small or when the screen of the display unit 1 is large. It is effective, and when it deviates from such a condition, erroneous input due to parallax cannot be prevented. In a touch panel input device that counts the number of times that a plurality of objects are simultaneously pressed and changes the determination area when the number exceeds a threshold, setting the threshold becomes a problem. If the threshold is too large, it is assumed that erroneous input is repeated many times. If the threshold value is too small, the determination area may be changed even when an erroneous input is made for a cause other than parallax.
On the other hand, there is a problem that the frequency of erroneous input increases when the user is watching. On the other hand, changing the screen angle of the display unit 1 so as to eliminate the parallax requires a separate mechanism for changing the screen angle, so that it can be applied only to an expensive device.

The present invention has been made in view of the above situation, and has as its object to realize a touch panel input device and an input method with less erroneous input due to parallax. Another object of the present invention is to realize a touch panel input device and an input method that are close and easy to use.

[0008]

In order to achieve the above object, a touch panel input device according to a first aspect of the present invention displays an image of a selection area indicating a selection item on a screen and displays the image of the selection item. A display unit for prompting selection and a light-transmitting panel disposed in front of the screen and having a coordinate system set therein, and the image is transmitted and displayed to the user, and as a result of the display, the user is A coordinate input unit that obtains, from the coordinate system, input coordinates of a location input by touching the panel, a storage unit that stores a selected area coordinate corresponding to the selected area in the coordinate system, and the storage unit that is stored in the storage unit. Calculate the distance between the selected area coordinates and the input coordinates determined by the coordinate input unit,
A coordinate comparing unit that specifies the selected selected item based on the calculated distance, and the selected area coordinates stored in the storage unit corresponding to the specified selected item are calculated by the distance calculated by the coordinate comparing unit. And a correction unit that corrects and rewrites only in the direction of the input coordinates.

In the touch panel input device having such a configuration, when the user makes a selection, the user touches the panel of the coordinate input unit so as to point to the image of the selected area displayed on the screen of the display unit and inputs. The coordinate input unit obtains input coordinates of the input location. The distance between the selected area coordinates corresponding to the selected area and the input coordinates is calculated by the coordinate comparing unit, and the selection item selected by the user is specified based on the calculation result.
Here, when the user touches the panel of the coordinate input unit and performs input with parallax, the input coordinates are shifted due to parallax, and the distance between the input coordinates and the selected area coordinates increases.
Therefore, the correction unit, by the distance calculated by the coordinate comparison unit,
Shift the selection area coordinates. This means that the coordinates of the selected area have been corrected by the amount of the parallax, and thereafter, when the same parallax is input to the panel with the same parallax, the probability of occurrence of an erroneous input due to the parallax can be reduced.

[0010] To achieve the above object, a second aspect of the present invention is provided.
The touch panel input device according to the aspect of the present invention comprises a display unit that displays an image of a selection area indicating a selection item on a screen, and a light transmission panel that is arranged in front of the screen and has a coordinate system set therein, A coordinate input unit that transmits the image to be displayed to the user and obtains the coordinates of a location input by touching the panel by the user from the coordinate system, and stores a selected area coordinate corresponding to the selected area in the coordinate system. A coordinate unit that calculates a distance between the selected area coordinates stored in the storage unit and the input coordinates obtained by the coordinate input unit, and specifies the selected selected item based on the calculated distance. And a detecting means for detecting that the user has once touched and input the panel and entered a new input coordinate by touching the panel for correction after the result of displaying the image. Distance calculating means for calculating a distance between the input coordinates before the correction and the selected area coordinates of the new selection item specified by the coordinate comparing section based on the new input coordinates; and When the input of the proper input coordinates is detected, the selected area coordinates stored in the storage unit corresponding to the new selection item specified by the coordinate comparison unit are corrected by the distance calculated by the distance calculation unit before the correction. And a correction unit that corrects and rewrites the input coordinates in a direction approaching the input coordinates.

[0011] By adopting such a configuration, when the user touches the panel for correction and performs input, the user tries to input correctly. Therefore, the distance calculated by the coordinate comparison unit with respect to the input for correction is almost close to parallax. By correcting the selection area coordinates based on this distance, when the same parallax is subsequently input to the panel with the same parallax, the probability of erroneous input due to parallax can be further reduced.

In the touch panel input device according to the first aspect, when the display unit displays on the screen an image of a selection area indicating a plurality of selection items on the correction unit, the touch panel input device is specified by the coordinate comparison unit. The selected area coordinates stored in the storage unit corresponding to the selected item are corrected and rewritten in a direction closer to the input coordinates by the distance calculated by the coordinate comparison unit, and the storage corresponding to the other selected items is rewritten. The coordinates of the selected area stored in the unit may be modified and rewritten in the same direction by the distance.

Further, in the touch panel input device according to a second aspect, when the display unit displays an image of a selection area showing a plurality of selection items on the screen, the coordinate comparison unit The selected area coordinates stored in the storage unit corresponding to the selected item specified before the correction are corrected and rewritten in a direction closer to the input coordinates before the correction by the distance calculated by the distance calculating means, and The selection area coordinates stored in the storage unit corresponding to the other selection items may have a function of correcting and rewriting the same distance in the same direction by the same distance.

Next, the operation of the touch panel input device will be described. FIG. 2 is an explanatory diagram illustrating an object.
The information processing device 10 transmits a control signal to the display unit 11 to instruct the user to display an image for allowing the user to select a selection item. The display unit 11 displays images of an arbitrary number of objects 21 on a screen. Each object 21
For example, as shown in FIG. 2, is schematically drawn in the shape of a key, and a number or the like is added for distinction.

Each of these objects 21 represents a selection item. The coordinate input unit 12 displays the image of the object 21 to the user through the screen of the display unit 11 and prompts the user to select a selection item. The user who has determined the selection item to be selected presses any one of the arbitrary number of objects 21 and touches and inputs the panel 12a of the coordinate input unit 12 with a fingertip or the like. The coordinate input unit 12 obtains the coordinates of the location touched by the user as the input coordinates S12. Here, when the range of the part touched by the user is wide, the coordinates of the center are set as the input coordinates S12. The coordinate input unit 12
The input coordinates S12 are output to the coordinate comparison unit 14.

It is stored in the state where it was done.

The coordinates for each of these objects 21
Is represented by the coordinate system of the panel 12a of the coordinate input unit 12.
And an image of each object 21 is viewed from the front.
Sometimes, each object 21 is located in the coordinate system of the panel 12a.
Indicates the position. Of each object 21
As coordinates, the entry number of each object 21

Judgment threshold (X₁, Y₁)-(X_N, Y_N) Are different values
May be common to all objects 21
No.

The coordinate comparing section 14, which has input the input coordinates S12 from the coordinate input section 12, firstly executes the step ST1 in FIG.
Step ST3 is repeated, and the distance between the input coordinates S12 and each object 21 is calculated.

The coordinates of the input coordinates S12 are represented by (X _IN ,
Y _IN ), and a variable indicating the entry number of the object 21 is I. In step ST1, the coordinate comparing unit 14 stores the center coordinates (X _I , Y _I ) of the object corresponding to the entry number I in the object effective coordinate table. read from the storage unit 13, in step ST2, the input coordinates _{(X iN, Y} iN) and the center coordinates _{(X I, Y} I) the distance _{d I} between the calculated by the following equation. d _I = √ ((X _IN −X _I ) ² + (Y _IN −Y _I ) ² )

In step ST3, the coordinate comparison unit 14
Stores the calculated distance d _I in a buffer or the like. The above steps ST1 to ST3 are repeated until the distance between all the objects 21 and the input coordinates S12 is obtained. In step ST4 when the repetition of steps ST1 to ST3 is completed, the coordinate comparison unit 14
Initializes a variable d _MIN for finding the minimum distance d _I to 0, and initializes a variable SEL for extracting the entry number of the object 21 having the minimum distance d _I to 0.

After step ST4, the coordinate comparison unit 14
Repeats steps ST5 to ST9 to find an object 21 whose distance is closest to the input coordinates 12 and whose distance falls within the range set by the determination threshold.

First, in step ST5, the coordinate comparing unit 1

In step ST7, the variable d at that time is_MINValue and distance d _I
And if they are equal or the distance d_IIf is small
The process proceeds to step ST8, where the determination threshold value THREI and the distance are set.

And step ST9 is not performed. Step ST

Also, step ST9 is not performed.

By repeating steps ST5 to ST9, if there is an object 21 closest to the input coordinate S12 and having the coordinate value of the input coordinate S12 within the range specified by the determination threshold, the object 21
Is set as a variable I.

In step ST10, the coordinate comparison unit 1
4 confirms the value of SEL, and when SEL is 0, notifies the information processing apparatus 10 that there is no selected object. If the value of SEL is not 0, the value of SEL is specified as the entry number of the selected object 21 in step ST11, and the value of SEL is notified to the information processing apparatus 10.

The operation up to the point at which the touch panel input device specifies the object 21 has been described above, but the user may input with parallax. If the input is performed without parallax, the vicinity of the center coordinate of the object 21 often becomes the coordinate value of the input coordinate S12. However, if there is parallax, the coordinate value of the input coordinate S12 is changed from the center coordinate as shown in FIG. Shift. Therefore, the object effective coordinate correction unit 15
Performs the following operation.

That is, the object effective coordinate correcting unit 15
Is the specified object 21 from the coordinate comparing unit 14.
D _I between the center coordinates of the coordinate system and the coordinate value of the input coordinate S12
Enter a, the center coordinates of the object effectively coordinate table storage unit 13 objects 21 that have been identified which is stored in a direction closer to the coordinate value of the input coordinates S12 distance d _I content only, rewriting and correct.

FIG. 5 is an explanatory diagram showing the correction of coordinates.
When the object effective coordinate correcting unit 15 corrects the center coordinates of the object 21, the range of the object 21 set by the determination threshold also shifts, so that the boundary 22 between the objects also substantially shifts. Therefore, when the user performs an input from the coordinate input unit 12 with the same parallax state after the correction of the center coordinates, the probability of occurrence of an erroneous input becomes extremely low.

As described above, in the touch panel input device of the first embodiment, the object effective coordinate correcting unit 1
5 and the center coordinates of the object 21 are the input coordinates S1
Since the center coordinates of the object 21 are corrected to have the coordinate value of 2, the probability that an erroneous input will occur thereafter can be reduced, and the mental and physical burden on the user can be greatly reduced.

[Second Embodiment] FIG. 6 shows a second embodiment of the present invention.
It is a lineblock diagram of a touch panel input device showing an embodiment. This touch panel input device includes a display unit 11, a coordinate input unit 12, an object effective coordinate table storage unit 13, and a coordinate comparison unit 14 similar to those of the first embodiment, and also has different object effective coordinates from the first embodiment. A correction unit 25 is provided. Object effective coordinate correction unit 2
5 basically functions in the same way as the object valid coordinate correcting unit 15 of the first embodiment, but differs from the object valid coordinate correcting unit 15 in that an instruction from the information processing device 10 is used as a trigger for operation.

The touch panel input device further includes:
A coordinate comparing unit 26 as a distance calculating unit and a coordinate / judgment result storing unit 27 are provided. The coordinate comparing unit 26 calculates the distance between the input coordinates different from those of the coordinate comparing unit 14 and the center coordinates of the object 21. The coordinate / determination result storage unit 27 holds the result of the adjacent determination between objects, the coordinate value of the previous input coordinate S12, and the object determination result.

Next, the operation of the touch panel input device shown in FIG. 6 will be described. The information processing device 10 transmits a control signal to the display unit 11 to instruct the user to display an image for allowing the user to select a selection item. The display unit 11 displays images of an arbitrary number of objects 21 on a screen. Each of these objects 21 represents a selection item. The coordinate input unit 12 displays the image of the object 21 to the user through the screen of the display unit 11 and prompts the user to select a selection item.

The user who has selected the selection item to be selected touches the panel 12a of the coordinate input unit 12 with his / her fingertip to input by pressing any one of the arbitrary number of objects 21. The coordinate input unit 12 obtains the coordinates of the location touched by the user as the input coordinates S12, and provides the input coordinates S12 to the coordinate comparison unit 14 and the coordinate / judgment result storage unit 27 for storage. The coordinate comparing unit 14 operates in the same manner as in the first embodiment, and specifies a selection item that is considered to have been selected by the user. Information on the specified selection item is notified to the information processing apparatus 10.

FIGS. 7A and 7B are explanatory diagrams showing the correction of an erroneous input. The user operates the panel 12 of the coordinate input unit 12.
By touching a and inputting the input coordinates S12, the selection item selected by the user is specified. When there is a parallax, for example, a numeral “1” is added as shown in FIG. 7A. Even if the user intends to select the object 21, the coordinates of the object 21 with the number "2" adjacent thereto may be the input coordinates S12.

When such an erroneous input occurs, the user uses a keyboard or the like (not shown) to notify the information processing apparatus 10 that correction is to be performed, and newly touches the panel 12a to input the input coordinates S12n. At this time, the user performs input without parallax because the correction is made.

The coordinate comparing section 14 specifies an object 21 indicating a new selection item based on the input coordinates S12n in the same manner as before correction. The information of the previously selected object 21 before the correction is stored in the coordinate / determination result storage unit 27, and the coordinate comparison unit 26 determines whether the selected object 21 is adjacent to the selected object 21 after the correction. If adjacent,
Further, the previous input coordinate S12 stored in the coordinate / judgment result storage unit 27 and the object 2 selected after the correction
1 is calculated by the coordinate comparing unit 26, and if the result is within a specified threshold, the object valid coordinate correcting unit 25 corrects the center coordinates of the selected object 21 after the correction before the correction. Is corrected to match the coordinate value of the input coordinate S12 of the above, and the content stored in the object effective coordinate table storage unit 13 is rewritten.

Object effective coordinate table storage unit 13
By rewriting the center coordinates stored in FIG.
As shown in (b), the boundary 22 between the objects determined by the determination threshold THRE also shifts according to the parallax.

In the touch panel input device of the second embodiment as described above, when correcting an erroneous input, the center coordinates of the object 21 are corrected, so that the probability of occurrence of an erroneous input thereafter can be reduced. Correction frequency can be reduced.

[Third Embodiment] FIG. 8 shows a third embodiment of the present invention.
1 is a configuration diagram illustrating a touch panel input device according to an embodiment. This touch panel input device includes an object effective coordinate correction unit 30 different from the object effective coordinate correction unit 15 in FIG. 1, and the other configuration is the same as the touch panel input device of the first embodiment.

In the touch panel input device shown in FIG. 8 having the object effective coordinate table 30, the display unit 11, the coordinate input unit 12, and the coordinate comparison unit 14 operate in the same manner as in the first embodiment. The object 21 selected by the user is specified from the input coordinates S12 input by the user. The object effective coordinate correcting unit 30 corrects the center coordinates of the object 21 specified by the coordinate comparing unit 14 in a direction approaching the coordinate value of the input coordinate S12 by the distance calculated by the coordinate comparing unit 14, and corrects another object. The center coordinates of 21 are similarly corrected.

As described above, in the touch panel input device of the third embodiment, the object effective coordinate correcting unit 3
Since 0 corrects the center coordinates of the plurality of objects 21 at the same time, the frequency of erroneous input when inputting continuously with the same parallax can be made lower than in the first embodiment.

Note that the present invention is not limited to the above embodiment, and various modifications are possible. There are the following modifications. In the third embodiment, the touch panel input device in which the object effective coordinate table 15 of the first embodiment is changed to the object effective coordinate table 30 has been described. It is also possible to substitute the effective coordinate table 30. By doing so, the center coordinates of the plurality of objects 21 are corrected each time correction is performed, so that the frequency of erroneous input when inputting continuously with the same parallax is made lower than in the second embodiment. Can do things,
The number of corrections can also be reduced.
