Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a touch panel correction device with improved operability in a customer operation type terminal using a touch panel.

[0002]

2. Description of the Related Art At present, automated teller machines of financial institutions such as banks and automatic ticket vending machines of railway stations are customer-operated terminals. In many of such customer operation type terminals, a touch panel detects a pressed position of a button displayed on the CRT.

[0003]

However, the above-mentioned prior art has the following problems. When operating the buttons a, b, and c as shown in FIG. 2, C
FIG. 3 shows the correlation between the buttons a, b, c displayed on the RT and the detection positions A, B, C corresponding to them. For accurate detection by the touch panel, as shown in FIG. 3, the buttons a, b, c displayed on the CRT and the detection positions A, B, C of the touch panel are
It must be in line with the operator's viewpoint position. That is, unlike the case of FIG. 3, when the viewpoint is shifted, the operator cannot operate the touch panel correctly.

That is, a customer who actually operates a terminal has a large difference in touch position depending on the height of each person, from children to adults or elderly people. For example,
As shown in FIG. 4, when the child presses the button b, the viewpoint may shift downward, and as a result, the touch panel may detect that the button was pressed at the detection position C. In this case, it is determined that the button c has been pressed. Further, as shown in FIG. 5, when an adult presses the button b, the viewpoint may shift upward, and as a result, the touch panel may detect that the button has been pressed at the detection position A. In this case, it is determined that the button a has been pressed. When such an erroneous judgment is made, conventionally, the customer himself / herself corrects the touch position by trial and error and inputs correct information.

[0005]

In order to solve the above-mentioned problems, a touch panel correction apparatus of the present invention is a customer who operates by detecting pressing of a button displayed on a display device through the touch panel. In the operation type terminal,
It is characterized by the following points.

(1) 1. A viewpoint position detecting section for detecting a viewpoint position for determining a correlation between a button position and a corresponding touch panel detection position is provided. 2. A correction amount setting unit that sets a correction reference amount when performing correction according to the viewpoint position determined by the viewpoint position detection unit. 3. A correction amount calculation unit that calculates a correction amount according to the deviation of the viewpoint position according to the correction reference amount set by the correction amount setting unit is provided. 4. A correction unit that corrects one of the button position and the corresponding touch panel detection position based on the correction amount calculated by the correction amount calculation unit.

(2) In (1), the viewpoint position detecting unit determines the viewpoint position from viewpoint position information stored in advance in a predetermined storage unit such as a host. (3) In (1), the viewpoint position detection unit detects the viewpoint position by a predetermined viewpoint position detection sensor.

[0008]

[Action]

(1) The viewpoint position detecting unit detects the viewpoint position of the customer based on the member information and the like obtained from the host. On the other hand, the correction amount setting unit sets in advance a correction reference amount for correcting the touch position corresponding to the shift of the viewpoint position. For example, it is the ratio of how many centimeters the viewpoint position is displaced and how many millimeters the touch position is displaced. The correction amount calculation unit calculates the correction amount by integrating the shift amount of the viewpoint position detected by the viewpoint position detection unit and the correction reference amount. Then, the correction unit shifts the touch position in the direction of the viewpoint position by the calculated correction amount. As a result, regardless of whether the customer is tall or short, the button and the touch position can be positioned on the line of sight so that the button can be operated accurately. In this way, the touch position (calibration position) can be automatically corrected based on the height of the customer, etc., and the operability of the customer-operated terminal can be improved.

(2) In (1), the customer operation type terminal generally operates by issuing a dedicated ID card to the member, so the height is also registered at the time of member registration, and the name is registered on the member host.
It should be managed together with the address. As a result, in the customer operation type terminal, when the card is inserted, it is possible to access the member host from the card reader and inquire about the height of the member.

(3) In (1), by detecting the position of the customer's viewpoint with a radar or the like, even if the position of the customer is displaced to the left or right, such displacement can be detected. As a result, it is possible to correct the touch position even when operating the buttons arranged and displayed in the horizontal direction of the CRT. As a result, it is possible to prevent an erroneous operation due to a left-right deviation of the viewpoint position.

[0011]

Embodiments of the present invention will now be described in detail with reference to the drawings. (First Embodiment) FIG. 1 is a block diagram of an embodiment of a touch panel correction device of the present invention. The illustrated apparatus includes a viewpoint position detection unit 1, a correction amount setting unit 2, a correction amount calculation unit 3, and a correction unit 4.

The viewpoint position detection unit 1 detects the viewpoint position of the operator on the customer-operated terminal. Here, the viewpoint position determines the correlation between the button position and the corresponding touch panel detection position. That is, in FIG. 3, the touch panel detection positions A, B, and C must be set on a straight line (dotted line in the drawing) connecting the viewpoint position v and the button display positions a, b, and c. Such a viewpoint position v can be determined by the height of the operator. That is, if the height is high, the viewpoint position v is high, and if the height is short, the viewpoint position v is low. Therefore, as shown in FIG.
Application form 1 when issuing an ID card 11 for a customer
Register the host 13 so that he / she can fill in the height in 2. Then, when the customer inserts an ID card for operating the terminal 14, the host 13 is inquired about the height of the customer.

The correction amount setting unit 2 sets a correction reference amount for performing correction according to the viewpoint position determined by the viewpoint position detecting unit 1. This correction reference amount is CR in FIG.
It is determined according to the distance x between the display surface of T and the surface of the touch panel. That is, if the distance x is large, the correction reference amount is increased to increase the correction amount for the deviation of the viewpoint position. The correction amount calculation unit 3 calculates the correction amount according to the deviation of the viewpoint position according to the correction reference amount set by the correction amount setting unit 2. That is, the correction amount is obtained by multiplying the shift amount of the viewpoint position and the correction reference amount.

The correction unit 4 corrects one of the button position and the corresponding touch panel detection position (touch position) based on the correction amount calculated by the correction amount calculation unit 3. For example, the touch position is corrected. As a result, as shown in FIG. 7B and FIG.
When the viewpoint position is shifted downward, the touch position is also shifted downward.

Next, the operation of the above-mentioned device will be described. A customer-operated terminal generally issues and operates a dedicated ID card for members. In this case, as shown in FIG. 6, the height is also registered at the time of member registration, and the member host manages it along with the name and address. In the customer operation type terminal, when the card is inserted, the host 13 is accessed from the card reader to inquire about the height of the member. Then, based on the height of the member obtained from the host 13, the button position and the touch panel position are corrected as shown in FIG. That is, if the height of the customer is higher than the standard, as shown in FIG.
If 0 and the height of the customer is lower than the standard, FIG.
As shown in, the touch position is B1. This allows
As shown in FIG. 8, for example, even when the customer is a child or the like, the button b and the touch position B1 are located on the line of sight, and the operation of the button b can be performed accurately.

(Second Embodiment) A customer who operates a customer-operated terminal generally operates while standing in front of the terminal or sitting down. Therefore, a sensor for detecting the height is installed in the terminal, and the height or sitting height of the customer is automatically measured. That is, a radar device or the like known as a sensor is provided on the upper portion of the terminal or the like to detect the position of the customer's forehead and the like, and the viewpoint position is determined from this position. The processing procedure for correcting the button position and the touch position after determining the viewpoint position is the same as that in the first embodiment.

Next, the correction in the horizontal direction will be described.
In the second embodiment, by detecting the viewpoint position of the customer with a radar or the like, even if the position where the customer stands is displaced to the left or right, such displacement can be detected.
Therefore, when operating the buttons d, e, f which are arranged and displayed in the horizontal direction of the CRT as shown in FIG. 10, the touch position is set to D0, E as shown in FIGS. 11 and 12.
It can be corrected to 0, F0 or D1, E1, F1. As a result, it is possible to prevent an erroneous operation due to a left-right shift of the viewpoint position.

The present invention is not limited to the above-mentioned embodiments, and it goes without saying that various modifications can be made. For example, in the above-described embodiment, the case where the detection position on the touch panel of the customer operation type terminal is corrected has been described, but the display position of the button may be corrected.

[0019]

As described above, according to the touch panel correction apparatus of the present invention, the button display position or the touch position is corrected according to the operator's viewpoint position.
It has the following effects. That is, whether the customer who actually operates the terminal is a child or an adult, it is possible to correct the deviation of the touch position due to the difference in height of each person. That is, the touch position of the touch panel and the display position of the button can be placed on a straight line from the viewpoint, and the operator can always operate the touch panel correctly. Therefore, it is possible to prevent an erroneous determination of the pressed position of the button from occurring, and prevent a situation in which the customer has to correct the touch position by trial and error.
