  Embodiments of the present invention will be described in detail with reference to the drawings.

[First Embodiment]
FIG. 1 shows an input device 100 according to a first embodiment of the present invention.

  The input device 100 includes a plurality of input units 102, a sound generation unit 103 disposed at each input unit 102, and a control unit 101 that controls the input unit 102 and the sound generation unit 103. The control unit 101 assigns different sounds to the positions of the input units 102. The control unit 101 generates a sound assigned from the sound generation unit 103 by superimposing at least a part of the assigned sounds.

  Since the sound generators 103 are arranged at the positions of the respective input units 102, the input device 100 can generate sounds such that sounds are emitted from the positions of the respective input units 102.

  As a specific example of the input device 100 according to the first embodiment of the present invention, a plan view and a cross-sectional view of the input device 100a are shown in FIGS. The input device 100a is assumed to be used for ATM.

  As illustrated in FIG. 2A, the input device 100 a includes ten input units 102 a corresponding to any number from “0” to “9”. No numbers are displayed on the input unit 102a. As shown in FIG. 2B, a sound generator 103a is embedded in each input unit 102a. The input unit 102a is, for example, an input key. The sound generator 103a is, for example, a speaker.

  Next, the operation of the input device 100a will be described.

  The control unit 101 (not shown in FIG. 2A) randomly assigns numbers from “0” to “9” to the input units 102a. In the case of this embodiment, the sound generator 103a is embedded in the input unit 102a. Therefore, randomly assigning each number to each input unit 102a means that each number is randomly assigned to each sound generating unit 103a.

  Next, the control unit 101 causes the sound generation units 103a arranged in the respective input units 102a to generate the respective sounds of numbers “0” to “9” almost simultaneously. At this time, the number which the voice which the sound generation part 103a utters means and the number assigned to each sound generation part 103a become the same. As a result, the ten sound generators 103a emit the voices of the numbers “0” to “9” almost simultaneously. FIG. 2C shows a state in which numerical voices are emitted from ten input units 102a almost simultaneously.

  The user listens to the voice of the number and specifies the position of the sound generator 103a that emits the number that the user wants to input. And input operation is performed using the input part 102a by which the specified sound generation part 103a is arrange | positioned.

  The input device 100a according to the present embodiment generates numeric sounds almost simultaneously from the sound generators 103a arranged in the input units 102a without displaying numbers on the input units 102a. As a result, the respective numerical sounds emitted from the sound generator 103a reach the user's ear in a mixed state. Then, the user listens to a desired numeric voice from among a plurality of numeric voices mixed together, and specifies a sound generator 103a that emits the numeric voice. The user can hear a desired numerical voice from a plurality of mixed numerical voices by the selective attention ability of the auditory auditory ability.

  The auditory selective attention ability is also called a cocktail party effect, and is an ability to selectively listen only to a sound of interest from a plurality of sounds having different sound source positions. It is this ability that allows people to extract and listen to specific conversations at party venues where many conversations are taking place.

  With this ability, the user can specify the sound generator 103a that emits a desired number from among a plurality of number sounds mixed together. For example, when the user intends to input “3”, he / she is conscious of listening to only the voice “3” from a plurality of numeric voices. Then, by the selective attention ability, the sound generator 103a that emits the numerical sound of “3” is selected from the ten sound generators 103a that generate the numerical sounds of “0” to “9” almost simultaneously. Can be identified.

  At this time, no numbers are displayed on the input unit 102a. For this reason, when the user is performing an input operation, even if there is a third party who is trying to steal the entered number or the ATM is equipped with a camera, the input used for the input operation It is almost impossible for a third party to guess the input number from the visual information such as the operation of the unit 102a and the user.

  In addition, it is almost impossible for a third party to guess the input number from the auditory information. This is because the selective attention ability is the ability to hear only the information to be heard. Since the user tries to hear only the inputted number from a plurality of number sounds in which number sounds from “0” to “9” are mixed, the number can be heard. On the other hand, the third party does not know what the numbers should be heard. For this reason, a plurality of numerical voices mixed with each other are recognized as noise by a third party.

  Thus, according to the input device 100 of this embodiment, when different sounds are emitted from the respective positions of the plurality of input units 102, at least some of the different sounds are overlapped. To emit. As a result, different sounds are mixed and the mixed sound reaches the user's ear. The user can hear a desired sound from the mixed sound by the selective attention ability of the auditory auditory ability. For this reason, the user can specify the sound generating unit 103 a that emits a desired sound, and can perform an input operation using the input unit 102 including the sound generating unit 103. On the other hand, since the third party does not know what the desired sound is, the mixed sound is recognized as noise by the third party. Therefore, the input information entered by the user is hardly known to the third party, and even if the movement of the user's hand and the input unit during the input operation are seen by the third party, Input information is rarely known to third parties.

  When there is an input from the input unit 102, the control unit 101 can use the information associated with the sound assigned to the input unit 102 with the input as input information. For example, when there is an input from the input unit 102a to which the voice “3” is assigned, the control unit 101 can assume that the information “3” is input.

  It is desirable that the sound assigned to the input unit 102 and the information associated with the sound represent the same thing. For example, it is desirable to associate the information “3” with the voice “3”. In this way, since the information “3” can be input from the input unit 102 in which the sound generating unit 103 that emits the sound “3” is arranged, the user can perform the operation based on the sound generated by the sound generating unit 103. Information can be input intuitively.

  The control unit 101 may assign different sounds to the positions of the respective input units, and generate the sound assigned from the sound generation unit 103 by overlapping at least some of the assigned sounds. Here, the sound is generated from the sound generation unit 103 by superimposing the sounds, and the sound is generated from the second sound generation unit 103 when the first sound generation unit 103 is generating sound. Means that. Thus, by overlapping at least a part of the assigned sounds, a sound recognized as noise by a third party can be generated.

  It is desirable that the control unit 101 generates the sounds assigned from the sound generation unit 103 almost simultaneously. Thereby, it is possible to make a third party recognize the sound generated by the sound generation unit 103 as noise more reliably.

  The sound generated by each sound generator 103 may be any sound that can be determined by a person as a different sound. Therefore, the sound generated by the sound generation unit 103 may be the same type of sound with a different pitch or tone. The kind of sound here refers to sound emitted from the same musical instrument, for example. Moreover, that each sound generation part 103 emits the same kind of sound indicates that each sound generation part 103 emits a guitar sound, for example.

  The sound generated by the sound generating unit 103 may be a sound of letters such as alphabets, “A”, “I”, “U”, “E”, “O”, in addition to numeric sounds. In this case, for example, when there is an input from the input unit 102a to which the voice “A” is assigned, it is desirable that the control unit 101 treats the information “A” as input. The sound generated by the sound generation unit 103 may be a voice of a word composed of a plurality of characters such as “Yama”, “Kawa”, and “Umi”. In this case, for example, when there is an input from the input unit 102 to which the voice “Yama” is assigned, it is desirable that the control unit 101 handles “Yama” information as input. Even in these cases, of course, it is not necessary to write information on what kind of information can be input by the input unit 102 such as letters and numbers on the input unit 102.

  As described above, the control unit 101 may randomly assign a sound to each input unit 102 position. By randomly assigning sounds, it becomes more difficult for a third party to guess the input number.

  The control unit 101 may perform a process of randomly assigning a sound to the position of each input unit 102 every time there is an input to the input unit 102. This makes it more difficult for a third party to guess the input number.

  The sound generator 103 may be a transparent diaphragm speaker using a piezoelectric element or the like. If such a sound generator 103 is employed, the input device 100 can be easily applied to a touch panel interface.

  Next, the electronic apparatus 105 of this embodiment will be described with reference to FIG. Specifically, the electronic device 105 includes an ATM, a computer, a portable terminal, a security system, and the like that require authentication to execute an operation.

  As illustrated in FIG. 3, the electronic device 105 includes an input device 100, a second control unit 104 connected to the control unit 101, and a storage unit 106 connected to the second control unit 104. The storage unit 104 stores a password. The input device 100 sends the input information input to the input device 100 to the second control unit 104 via the control unit 101.

  The second control unit 104 compares the input information received from the control unit 101 with the password stored in the storage unit 104 and determines whether the input information and the password match. When it is determined that these pieces of information match, the second control unit 104 executes subsequent processing, and when it determines that these pieces of information do not match, the second control unit 104 does not execute subsequent processing. For example, when the electronic device 105 is an ATM, if it is determined that the input information and the password match, the process proceeds to an input process for a transfer or deposit procedure, and if it does not match, no procedure is processed.

  As described above, the input information input to the input device 100 is hardly known to a third party. Therefore, the user can use the electronic device 105 having the input device 100 without worrying about a password being stolen by a third party.

[Second Embodiment]
Next, an input device according to a second embodiment will be described. The input device according to the present embodiment is characterized in that a plurality of sounds are emitted from a sound generation unit arranged at a position different from the input unit so that a plurality of sounds are emitted in a pseudo manner from the respective positions of the plurality of input units. And

  FIG. 4 shows an input device 200 according to this embodiment. The input device 200 includes a plurality of input units 202, a sound generation unit 203 that is arranged at a position different from the input unit 202, and generates a sound, and a control unit 201 that controls the input unit 202 and the sound generation unit 203. Have. The control unit 201 assigns different sounds to the positions of the input units 202. The control unit 201 generates the sound assigned from the sound generation unit 203 by superimposing at least a part of the assigned sounds.

  The sound generator 203 generates stereophonic sound. Thereby, even if the input part 202 and the sound generation part 203 are arrange | positioned in a different position, the sound generation part 203 generates a sound so that sound may be emitted from the position of each input part 202. Can do.

  Therefore, even if the input unit 202 and the sound generation unit 203 are arranged at different positions in the input device 200, the user can emit the sound assigned to each input unit 202 from the position of the input unit 202. I can hear as if

  The sound generator 203 may be headphones. If the headphones are used, the sound generated by the sound generator 203 can be heard only by the user without being heard by a third party. This makes it almost impossible for a third party to steal input information.

  Further, the sound generation unit 203 may be a plurality of speakers arranged at a different location from the input unit 202. In this case, the plurality of speakers generate stereophonic sound such as stereo sound or surround sound.

  The method for generating the stereophonic sound is not particularly limited. The stereophonic sound is generated using a general stereophonic sound generation method such as binaural recording or reproduction method.
