Abstract

PROBLEM TO BE SOLVED: To enable even a visually handicapped person to input a personal identification number from a pin pad. SOLUTION: When a touch panel 5 mounted on the pin pad 4 is touched and pressed with a finger cap 3 put on a fingertip, a numeral signal corresponding to a coordinate signal of a depressed key is transmitted to the finger cap 3. The finger cap 3 receives the numeral signal and stereoscopically generates a Braille matrix of the numeral inside it. An operator traces the Braille matrix with the fingertip and tactually senses a kind of the numeral of the key. Thus, even the visually handicapped person can input the personal identification number by using the pin pad 2.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a pin pad (Pe pad).
The present invention relates to an input device having a rsonal identity number (PAD) and used for a POS terminal or a home terminal for home banking, etc., which is compatible with a debit card, and particularly to an input device useful for a visually impaired person.

[0002]

2. Description of the Related Art A touch panel is widely used as an input device for the above-mentioned applications. However, a normal touch panel requires key selection by visual confirmation. Therefore, in order to enable such a touch panel to be operated even by a visually impaired person, a Braille forming unit is provided corresponding to a key position on the surface of the touch panel (Japanese Patent Laid-Open No. Hei 8-221205).
Setting a Braille plate (Japanese Patent Laid-Open No. 8-329314)
No.) is proposed.

[0003]

On the other hand, recently, a lot of research on virtual reality (VR, virtual reality) has been made, and attention has been paid to a simulator using a virtual environment formed by the virtual environment and a human-machine interface. ing. An object of the present invention is to configure an input device that enables a visually handicapped person to obtain a more convenient and realistic operation feeling.

[0004]

According to the present invention, a touch panel is mounted on an operation surface of a pin pad, and a symbol display on the operation surface corresponding to a touching position of the touch panel is represented as a three-dimensional braille matrix by a fingertip of an operator. Is provided, and by reading the symbol type from the tactile sensation of the Braille matrix, even a visually impaired person can operate the touch panel (claim 1).

[0005] In this case, by providing a means for changing the arrangement of a plurality of symbols on the operation surface and a key means for randomly changing the arrangement of the symbols each time the operation is performed, it is necessary to input a password. The arrangement of the symbol display can be changed in accordance with the condition (2) to maintain confidentiality. Further, by providing a key means for arranging the randomly changed arrangement of the symbol display in a predetermined initial state, the symbol display can be arranged and the convenience of input can be prioritized (claim 3).

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a perspective view of a terminal showing an embodiment of the present invention in a POS system compatible with, for example, a David card. In FIG. 1, a pin pad 2 is provided on a register body 1 via a wire or wirelessly, and a finger cap 3 attached to a fingertip of an operator is provided on the pin pad 2.
Is connected. Numerical symbols (1 to 9, 0) are displayed on the operation surface 4 of the pin pad 2 in the drawing, and a touch panel 5 is mounted on the surface thereof.

As shown in FIG. 2, in the initial state, the numerical symbols of the pin pad 2 are arranged in a fixed arrangement, that is, a regular arrangement in ascending order. When the random key 6 is pressed from this state, for example, as shown in FIG. 3, the numeric arrangement changes randomly, and this random arrangement changes every time the random key 6 is pressed. When the clear key 7 is pressed in the random state shown in FIG. 2, the numeral and symbol return to the initial state shown in FIG.

In FIG. 2 or FIG. 3, when a user presses an arbitrary numeric key of the touch panel 5 with the finger cap 3 at the time of inputting the personal identification number, a coordinate signal of the key is output from the touch panel 5 and the coordinate signal is output to the pin pad 2. Is input to an input conversion unit (not shown). When the coordinate signal is input, the input conversion unit converts the coordinate signal into a symbol type signal based on the type information of the numeric symbol stored in the information storage unit in advance corresponding to the coordinate position of the key, and outputs the signal. This symbol type signal is sent to the finger cap 3.

Here, the finger cap 3 is an actuator mounted on the fingertip of the operator. The finger type signal is inputted, and the symbol (numerical) information corresponding to the symbol type signal is three-dimensional braille inside the input signal. Generate as a matrix. Therefore, the operator touches this braille matrix with his fingertips, and reads the actual point numbers with his fingertips.
Recognize that number. Then, when a target number is reached, the number is specified by, for example, pressing a push button (not shown) with another hand. By this repetition, the number is input to the register body as a password. The braille matrix is not only for numbers, but also for kanji, kana,
Alternatively, it can be a pictogram.

[0010]

As described above, according to the present invention, the operation information corresponding to the coordinate position of the touch panel is touched to the fingertip of the operator, and even a visually impaired person can perform input using the touch panel. Further, by changing the arrangement of the symbol display at random, it is possible to maintain confidentiality at the time of inputting the personal identification number.

FIG. 1 is a perspective view of a terminal according to an embodiment of the present invention.

FIG. 2 is an enlarged view of a pin pad in FIG.

FIG. 3 is a diagram showing a state in which the arrangement of symbols displayed on the pin pad operation surface in FIG. 2 is randomly changed.
