Description

  The present invention relates to a character information receiving apparatus that receives input of character information from a user, and more specifically, to a character information receiving apparatus that can display the character information while hiding the display.

  2. Description of the Related Art Conventionally, there are devices such as password authentication devices that accept input of character information from a user and display the received character information on a screen so that the user can confirm the received character information. In such an apparatus, various proposals have been made to prevent others from knowing the password when entering the password.

For example, Patent Literature 1 includes a display unit, a selection key, a confirmation key, a control unit that changes a selection target number displayed on the display unit at a predetermined time period and a storage unit while the selection key is pressed. The provided password input device is described. In this personal identification number input device, the control unit stops changing the number when the selection key is no longer pressed. As a result, the number to be selected can be changed according to the length of time that the selection key is pressed and then the pressing is stopped. If the number displayed on the display unit is a desired number, the user presses the confirmation key. At this time, the control unit stores the determined number in the storage unit, and changes the display of the number on the display unit to *. Japanese Patent Laid-Open No. 2004-228688 may make it difficult for another person to discriminate the selected number even if the movement of the finger inputting the password can be seen by another person by configuring the password input device in this way. I can do it.
JP 2001-306826 A (published November 2, 2001)

  However, in the technique of Patent Document 1, a character is easily read by another person until the confirmation key is pressed. On the other hand, if the selected character is not displayed at all, the user cannot confirm whether or not the selected character is appropriate, so that erroneous input is likely to occur and the convenience for the user is reduced.

  Accordingly, in view of the above-described conventional problems, an object of the present invention is to provide a character information receiving apparatus that is difficult for others to read character information and does not reduce convenience for the user.

  In order to solve the above-described problem, the character information receiving apparatus according to claim 1 includes a key to be pressed by the user, and receives an input from the user through the pressing of the key. A character information receiving key, a receiving unit that can receive character information from a user by pressing the character information receiving key, and a character according to the character information received by the receiving unit through the character information receiving key. A character selection unit for selecting an image, a display unit for displaying an image, and a display control unit for controlling the display unit. The display control unit is operated by pressing the character information acceptance key. The display of the character selected by the character selection unit is started, and the display unit is controlled so as to hide the character when a predetermined time elapses after the character information reception key is not pressed. You have me.

  The character information reception device starts displaying the character selected by pressing the character information reception key, and hides the character when a predetermined time elapses after the character information reception key is not pressed. It has become. That is, when the character information acceptance key is released, the character is automatically hidden, so that it is difficult for others to read the character. Further, according to the character information receiving device, the longer the time for which the user presses the character information receiving key, the later the timing at which the character is hidden on the display unit, and the shorter the pressing time, the earlier the timing. That is, the character information receiving apparatus can adjust the timing for hiding characters in accordance with the key operations of individual users. Therefore, according to the character information receiving apparatus, when the user wants to hide the character early, such as when there are many people around, the character is quickly hidden according to the desire, and long when the user wants to confirm each character reliably. Character display according to the situation, such as displaying, is possible. In other words, according to the character information receiving apparatus, it is difficult for another person to read the character information, and the convenience for the user is hardly lowered.

  Moreover, as described in claim 2, in the character information receiving apparatus according to claim 1, the predetermined time may be a constant.

  Further, as described in claim 3, in the character information receiving apparatus of claim 1, the predetermined time may be 0 (zero). By doing so, since the character is hidden as soon as the character information acceptance key is not pressed, the effect of making it difficult for others to read the character is further enhanced.

  According to a fourth aspect of the present invention, in the character information receiving device according to the first aspect, the display control unit increases the predetermined time as the time during which the character information receiving key is continuously pressed is longer. You may come to do.

  According to a fifth aspect of the present invention, in the character information receiving device according to any one of the first to fourth aspects, the display control unit determines that the time when the character information receiving key is continuously pressed The display unit may be controlled so as to start displaying the character selected by pressing when a predetermined time is reached.

  According to this character information receiving device, if the time during which the character information receiving key is continuously pressed is shorter than the other predetermined time, the character selected by the pressing is not displayed on the display unit. Therefore, the effect of the present invention that the display of characters can be hidden according to the situation can be further enhanced.

  According to a sixth aspect of the present invention, in the character information receiving device according to any one of the first to fifth aspects, the character selecting unit receives the character information from the user via the character information receiving key. Before the acceptance, the initial character is selected, and the initial character may be changed at random.

  According to this character information reception device, the character selection unit is in a state of selecting an initial character before input by the user via the character information reception key. Therefore, when inputting the character information, the user can input the desired character information by changing the initial character or accepting the initial character as it is through the receiving unit. Can do. At this time, according to the character information receiving apparatus, since the initial setting character is randomly changed, it is difficult for another person to predict the character information from the movement of the user's finger or the like when inputting the character information.

  In addition, as described in claim 7, the character information receiving device according to any one of claims 1 to 6 further includes a speaker that emits sound, and a sound control unit that controls the speaker, The voice control unit is configured to control the speaker so as to generate a sound in response to the key press, and to adjust the volume of the sound in response to the key press according to the user profile information. It may be changed.

  According to this character information receiving apparatus, the volume of sound can be changed according to the profile information of each user, so that the convenience for the user is further enhanced.

  In addition, as described in claim 8, the character information receiving device according to any one of claims 1 to 6 further includes a speaker that emits sound and a sound control unit that controls the speaker, and the sound The control unit is configured to control the speaker so as to emit a sound in response to pressing of the key, and from when a certain key is pressed to when the next key is pressed. The speaker may be controlled such that the shorter the interval, the shorter the sound generated in response to pressing of the next pressed key.

  Since the speaker emits a sound in response to the key press, if the interval at which the key is pressed becomes shorter, the interval between the sounds made by the speaker also becomes shorter. The shorter this interval is, the more difficult it is for the user to recognize sound breaks (intervals). If the breaks in the sound cannot be recognized in this way, it becomes difficult for the user to confirm whether the character information receiving device has recognized the key press, that is, whether the user's input has been received, which may cause confusion. There is sex.

  The present inventors have noted that the shorter the interval between pressing a certain key and the next key, the shorter the interval from pressing the next key to further pressing the next key. The character information receiving device according to claim 8 is provided with a voice control unit, so that a speaker corresponding to the pressing of the next key becomes shorter as the interval from pressing a key to pressing the next key becomes shorter. The sound from can be shortened. As a result, the character information receiving apparatus can widen the interval between the sound corresponding to the next key and the sound corresponding to the pressing of the next key. By doing so, the character information receiving apparatus can make the user recognize a break in sound and easily confirm that the user's input has been received.

  The character information receiving apparatus of the present invention adjusts the timing of hiding the character display according to the situation so that the character is not seen by a third party or easily visible to the user, particularly by the display control unit. be able to. That is, according to the present invention, a character information receiving apparatus is realized that is difficult for others to read character information and that does not reduce the convenience for the user.

  Hereinafter, an embodiment when the present invention is applied to a password authentication apparatus will be described. In addition, this invention is not limited to this embodiment, It can apply to the various character information reception apparatus which receives a character input from a user. The password authentication apparatus described below can be applied to ATM (Automated Teller Machine), information management system, and the like.

[1] Password Authentication Device FIG. 1 is a block diagram of the password authentication device 1 of this embodiment. The password authentication device 1 includes a receiving unit 10 that can receive instructions from the user when pressed by the user, an ID card reading unit 2 that reads information such as an ID number from the user's ID card, a receiving unit 10, A control device 30 that performs a processing operation based on contents received by the ID card reading unit 2, a speaker 4 that operates under the control of the control device 30, a display unit 5, and the like are provided.

  The reception unit 10 recognizes that the selection key group (character information reception key) 11, the confirmation key 12, the cancel key 13, and these keys are pressed, and sends information about which key is pressed to the control device 30. An input recognition unit 14 and the like for transmission are provided. The keys 11 to 13 are shown in the plan view of FIG.

  The ID card reading unit 2 can acquire information necessary for the user information acquisition unit 36 to extract profile information about the user and for the password authentication unit 35 to determine whether the user and the password match. If so, it can be replaced with another device. Note that the password authentication device 1 may not be provided with the ID card reading unit 2 but may receive an input of an ID number from the user via the receiving unit 10.

  The control device 30 displays the display unit 5 based on the character selection unit 31 that selects a number according to the content received by the reception unit 10, the number selected by the character selection unit 31, the acquisition content of the user information acquisition unit 36 described later, and the like. A display control unit 32 to be controlled, an initial setting unit 33 for initial setting of display contents on the display unit 5, a confirmed content holding unit 34 for holding a confirmed one of contents input by the user via the receiving unit 10, and a password Based on the password authentication unit 35 that performs authentication, the user information acquisition unit 36 that acquires user information such as the user's age based on the ID number acquired by the ID card reading unit 2, the acquisition content of the user information acquisition unit 30, and the like A voice control unit 37 for controlling the speaker is provided.

  The speaker 4 can emit a click sound when each key (selection key group 11, confirmation key 12, cancel key 13) of the reception unit 10 is pressed. In addition to the click sound, the speaker 4 may appropriately emit a sound such as an operation guide.

  The display unit 5 is a display device including a display surface 51 (see FIG. 2) such as a liquid crystal display panel, and can present various information to the user.

  The password authentication device 1 further includes an operation panel 20. FIG. 2 shows a plan view of the operation panel 20. As shown in FIG. 2, the operation panel 20 is provided with a display surface 51, a plus key 11 a and a minus key 11 b as a selection key group 11, a confirmation key 12, a cancel key 13, and the like.

[2] Password Accepting Operation The operation of the password authentication device 1 when accepting a password (character information) will be described with reference to FIGS. FIG. 3 is a flowchart showing the password receiving operation, and FIGS. 4 to 8 are plan views showing an example of a screen displayed by the display unit 5 in each step included in the password receiving operation of FIG.

  In the present embodiment, it is assumed that the password has four digits and is all numbers. However, of course, the present invention is not limited to this, and the number of digits of the password, the type of characters used in the password (alphabet, symbols, combinations of numbers, alphabets, symbols, etc.), etc. can be changed as appropriate. It is.

  First, the control device 10 randomly selects one number in the initial setting unit 33, and uses this number as an initial setting value of a number (selected character) selected as the first digit in the character selection unit 31 ( S1 and S2 in FIG. As described above, when the initial setting unit 33 randomly selects the initial setting value, it becomes difficult for another person to predict the password from the movement of the user's finger. The display control unit 32 causes the display unit 5 to display a screen P1 for requesting input of the first digit of the password (S3 in FIG. 3, FIG. 4). At this time, the screen P1 is provided with a message for prompting an input such as “Please enter your password” and a column for displaying the entered password. The initial setting value of is displayed. In FIG. 4, the initial setting value is 5. The column corresponding to the digit to be input, that is, the display of “5” in FIG. 4 is displayed by blinking the cursor, reversing the display color, or by surrounding it with a square as shown in FIG. It is highlighted.

  If any one of the selection key groups 11 is pressed (Yes in S4), the first digit number in the character selection unit 31 is changed in response to the pressing (S5). Specifically, when the plus key 11a is pressed, the character selection unit 31 changes the selected character to a larger value, and when the minus key 11b is pressed, the character selection unit 31 changes the value to a smaller value. In the screen P2 of FIG. 5, “6” is selected as the first digit number by pressing the plus key 11a on the screen P1.

  From the recognition contents of the input recognition unit 14, the display control unit 32 reaches the first predetermined time (another predetermined time) N in which the pressing time (time when the selection key group 11 is continuously pressed) A is set in advance. If it is determined that the display has been made (Yes in S6), the display unit 5 is controlled to display the number changed in Step S5 (S7). The first predetermined time N can be set to 0 (zero) and can be set as appropriate. When the pressing of the selection key group 11 is stopped (Yes in S8), and then the non-pressing time (time in which none of the keys 11 to 13 is pressed) B reaches the second predetermined time (predetermined time) M (Yes in S9). ), The display control unit 32 controls the display unit 5 so that the display of the first digit is an abbreviated character display, that is, “*” (S10 in FIG. 3, screen P3 in FIG. 6).

  If the pressing is stopped while the above-described pressing time A is less than the first predetermined time N (No in S6), the display control unit 32 changes the first digit to the obfuscated character display as soon as the pressing is stopped ( S11 → S10).

  Once the pressing is released (Yes in S11 or S8), when the selection key group 11 is pressed again, the control unit 30 repeats the same operation from step S5 described above (S10 → S4). That is, in this embodiment, the character selection unit 31 selects a number according to the number of times the selection key group 11 is pressed. That is, the character selection unit 31 changes the selected character to a value larger by 1 each time the plus key 11a is pressed once, and changes the selected character to a value smaller by 1 every time the minus key 11b is pressed once. For example, when an alphabet is used as a password instead of a number, if the initial setting value is C, the selected character is D when the plus key 11a is pressed once, and the selected character is pressed when the minus key 11b is pressed once. The character selector 31 is configured so that becomes B.

  Even when the number is selected via the selection key group 11 and the process returns to step S4, or when the number is not changed with the initial setting value, if the confirmation key 12 is pressed (No in S4 → (Yes in S12), the number selected at that time is confirmed. Specifically, the display control unit 32 controls the display unit 5 to display the k-digit number for a certain period of time and then change it to a hidden character display (S13 → S14 in FIG. 3), and the confirmed content holding unit 34 This number k is held (S15). Thereafter, the same operation is repeated for the next digit until the fourth digit is input (No → S17 → S2 in S16). By the above operation, for example, when the confirmation key 12 is pressed in the selection of the first digit, the display unit 5 switches the display from the screen P3 in which the first digit is a letter in step S10 to the screen P2 (S13), Next, the screen is switched to the screen P4 in FIG. 7 in steps S14 and S3. Step S13 may not be performed.

  When the numbers up to the fourth digit have been entered (Yes in S16, screen P5 in FIG. 8), the password authentication unit 35 determines whether or not the four-digit number held in the confirmed content holding unit 34 is appropriate as the password. To do.

  If the cancel key 13 is pressed during the operation (Yes in S18), when the first digit is input, a series of operations are performed again for the first digit (Yes in S19 → S2). A series of operations is performed again for the previous digit (No in S19 → S20 → S2).

[3] First predetermined time N and second predetermined time M
The first predetermined time N may be 0 (zero). That is, when a certain digit (k-th digit) is input, the display control unit 32 may control the display unit 5 so that the k-th digit is displayed at the same time as the selection key group 11 is pressed. . If the first predetermined time N is a numerical value greater than 0, for example, about 0.1 to 0.5 seconds, the user can quickly enter a number by pressing the selection key group 11 once or several times quickly. When selected, the selected number is not displayed on the display unit 5, and it becomes difficult for others to read the input content.

  The second predetermined value M may be a constant or a variable that changes depending on the pressing time A.

  When the second predetermined value M is a constant, for example, when the first predetermined time N is set to 0 and the second predetermined value M is set to 0.2, the time (display time) for displaying the number is (selection key group 11). (Pressing time + 0.2 seconds). That is, the display control unit 32 controls the display unit 5 so as to continue displaying numbers for the second predetermined time M even if the selection key group 11 is released. The second predetermined time M may be 0 (zero) or about 0.1 to 0.2 seconds. The shorter the second predetermined time M, the greater the effect that the password is difficult for others to read, and this effect is greatest when the second predetermined time M is set to zero. On the other hand, the longer the second predetermined time M is, the easier it is for the user to confirm the password.

  On the other hand, when the second predetermined time M is a variable, the second predetermined time M may be set longer as the pressing time A becomes longer. For example, the second predetermined time M may be determined by a function that is a linear function of the pressing time A and has a positive slope. More specifically, the second predetermined time M can be a multiple of the pressing time A. For example, assuming that the second predetermined time M is twice the pressing time A, when the selection key group 11 is pressed for 0.5 seconds, the number is displayed for 1 second that is twice as long after the pressing is released, and pressed for 1 second. Sometimes it may be displayed for 2 seconds.

  Whether the second predetermined time M is a constant or a variable, the display control unit 32 is configured to control the display unit 5 so that the display time becomes longer as the pressing time A is longer as described above. Thus, the display time can be controlled in accordance with various conditions such as individual characteristics of the user or the situation around the password authentication device 1 when inputting characters. Specifically, a person who takes a long time to operate a key or wants to display a selected character for a long time, such as an elderly person, lengthens the display time by lengthening the pressing time of the selection key group 11. Can do. In addition, when there are many people around the table, the user can shorten the display time by shortening the pressing time.

  In the above embodiment, the character selection unit 31 selects a character according to the number of times the selection key group 11 is pressed. However, the present invention is not limited to this, and the character selection unit 31 may select different characters depending on the pressing time A of the selection key group 11. That is, when the user starts to press the plus key 11a, the selected character is changed to a value that is 1 larger than the initial setting value. By further pressing, the selected character is changed to a value that is larger by 1 every 0.5 seconds, for example. Thus, the character selection part 31 may be comprised. In this case, when the minus key 11b is pressed, it may be changed to a smaller value by one.

  However, in the password authentication device 1 of the present embodiment, the selected character is preferably determined by the number of times the selection key group 11 is pressed, as shown in the flowchart of FIG. This is because, as described above, the display control unit 32 controls the display time by the display unit 5 in accordance with the pressing time A of the selection key group 11. When the selected character is determined by the number of times of pressing, the display time is adjusted regardless of the numerical value difference between the character to be selected by the user and the initial setting value of the selected character, rather than being determined by the pressing time. Can do.

  Further, in the above embodiment, the display control unit 32 and the display unit 5 hide the selected character in the k-th digit by using the hidden character display when the non-pressing time B reaches the second predetermined time M ( S10, S15), but it is only necessary to be able to hide the selected character so that it cannot be seen by others, and is not limited to this configuration. For example, the display control unit 32 and the display unit 5 may turn off the display of the selected characters instead of the prone characters.

[5] Voice Control Matched with User Profile Information Next, voice control will be described. Prior to the processing operation shown in the flowchart of FIG. 3, that is, before step S1, the password authentication device 1 may perform the following operation.

  That is, the password authentication device 1 may acquire an ID number from the user's ID card by the ID number reading unit 2. And the user information acquisition part 36 reads user information, such as a user's age, from the memory which is not shown based on the ID number which the ID card reading part 2 acquired.

  During the processing operation of FIG. 3, when any of the keys 11 to 13 is pressed, the voice control unit 37 controls the speaker 4 to emit a click sound in response to the pressing. At this time, the type and magnitude of the sound emitted by the speaker 4 are changed according to the content acquired by the user information acquisition unit 30 and the screen displayed on the display surface 51.

  For example, when the user's age is over a predetermined age (for example, over 60 years old), or when there are circumstances such as difficulty in hearing, the voice control unit 37 is configured to emit a louder sound than that for other users. 4 can be controlled. Since the voice control unit 37 is configured in this manner, the user can easily recognize the sound.

[6] Voice control in accordance with the speed of the user's key operation The voice control unit 37 may control the speaker 4 in accordance with the speed of the user's key operation. Specifically, as described in [5] above, the voice control unit 37 controls the speaker 4 so as to emit a click sound when any of the keys 11 to 13 is pressed. It has become. In particular, during the processing operation of FIG. 3, the voice control unit 37 clicks the next pressed key as the interval between pressing any one of the keys 11 to 13 and the next pressing key increases. The sound is made longer. In other words, the shorter the interval, the shorter the click sound of the next pressed key. That is, the longer the user takes his / her hand from the keys 11 to 13, the longer the sound emitted from the speaker 4 when the user presses the key, and the shorter the time, the shorter the sound.

  For example, the reference value R of the key press interval is 0.5 seconds. At this time, if the plus key 11a is pressed and then the plus key 11a is no longer pressed and the minus key 11b is pressed after 0.5 seconds or more, 0.2 seconds is received in response to the pressing of the minus key 11b. The sound control unit 37 controls the speaker 4 so as to emit a click sound having a length of. On the other hand, when the minus key 11b is pressed within 0.5 seconds after the plus key 11a is no longer pressed, the voice control unit 37 does not emit a click sound in accordance with the pressing of the minus key 11b. The speaker 4 is controlled. That is, according to this example, if the key press interval D is D <0.5, the click sound length S is S = 0, and if D ≧ 0.5, S = 0.2.

  In this example, the case where the minus key 11b is pressed after the plus key 11a is pressed has been described as an example. Of course, the case where the plus key 11a is continuously pressed is similarly pressed later. The length of the click sound of the key is controlled according to the key press interval.

[7] Other forms of key configuration In the above [1] to [6] fields, the selection key group 11 is the plus key 11a and the minus key 11b, but the selection key group 11 may have other configurations. . For example, as in the operation panel 21 shown in the plan view of FIG. 9, the selection key group 11 may be a numeric keypad 11c. In the field [2], the character selection unit 31 selects a character according to the number of times the selection key group 11 is recognized or the length of the time for which the input recognition unit 14 recognizes. Then, the character selection part 31 selects a character according to which key was pressed among the numeric keys 11c.

[8] Configuration of Control Device 30 Each block of the control device 30 may be configured by hardware logic, or may be realized by software using a CPU. That is, the control device 30 includes a CPU (central processing unit) that executes instructions of a control program for realizing each function, a ROM (read only memory) that stores the program, a RAM (random access memory) that expands the program, A storage device (recording medium) such as a memory for storing the program and various data may be provided. That is, the object of the present invention can also be achieved by a computer (CPU or the like) reading and executing the program code recorded on the recording medium.

  Examples of the recording medium include tape memory such as magnetic tape and cassette tape, magnetic disk such as hard disk, optical disk such as CD-ROM, MO, MD, DVD, and CD-R, card memory such as IC card, and the like. Semiconductor memories such as EPROM, EEPROM, and flash ROM can be used.

  As described above, techniques obtained by appropriately combining the configurations described in the different columns are also included in the technical scope of the present invention, and techniques obtained by combining conventionally known techniques are also included in the technical scope of the present invention. .
