  Hereinafter, an embodiment in which a mobile communication device with a Braille display function according to the present invention (hereinafter simply referred to as a “mobile communication device”) is embodied will be described with reference to the drawings. FIG. 1 is a block diagram showing a configuration of a mobile communication device, and FIG. 2 is a plan view of the mobile communication device.

  The mobile communication device 10 according to the present embodiment can transmit and receive mail, and can display the content of the received mail and the content input by the user in braille. Specifically, as shown in FIGS. 1 and 2, the mobile communication device 10 includes an antenna 11, a wireless unit 12, a data processing unit 13, a storage unit 14, an input unit 15, a display unit 16, a speaker 17, and an operation unit 18. It is configured to include.

  The wireless unit 12 includes a transmission unit 121 and a reception unit 122. The transmission unit 121 transmits information input from the data processing unit 13 to the outside (such as a radio base station) via the antenna 11. The receiving unit 122 outputs information received via the antenna 11 to the data processing unit 13.

  The storage unit 14 stores information input from the data processing unit 13 and outputs already stored information to the data processing unit 13. The storage unit 14 stores a dictionary 141 and a braille conversion table 142. The dictionary 141 stores hiragana corresponding to kanji, and the braille conversion table 142 stores braille corresponding to normal characters (hiragana, katakana, alphabets, numbers, etc.). That is, the dictionary 141 is for converting kanji into hiragana, and the braille conversion table 142 is for converting ordinary characters into braille. The storage unit 14 also stores a program for causing the data processing unit 13 to function. Note that data such as a program and a dictionary stored in the storage unit 14 can be read and set from a setting external device 20 such as a personal computer. That is, by receiving the setting data from the setting external device 20, the dictionary, the program, and the like can be updated.

  The input unit 15 includes an input touch panel 151 and a touch pen 152. When the tip of the touch pen 152 is brought into contact with the touch panel 151, the contact position is input to the data processing unit 13 as coordinate information. Then, braille or characters can be input by coordinate information obtained by bringing the touch pen 152 into contact with the touch panel 151. When inputting from the touch panel 151, a character determination unit 181 (to be described later) is pressed every time one character is input in order to clarify that the input of one character has been completed and to enable the next new character to be input. .

  The display unit 16 is for displaying information received from the outside and contents input from the input unit 15 in braille, and in this embodiment, 20 brailles can be displayed. Braille is composed of a total of 6 points in 3 rows and 2 columns (vertical 3 dots and horizontal 2 dots), and one character is expressed by a combination of the irregularities of these points. Each dot constituting the braille is configured by a movable piece 161 arranged in a lattice pattern on the surface of the display unit 16. The movable piece 161 is made of a magnetic material, and can be projected and retracted from the surface of the display unit 16 using the principle of an electromagnet. Then, in accordance with an instruction from the data processing unit 13, protrusion / retraction is controlled and a desired Braille display is performed.

  The speaker 17 is used to output information received from the outside and contents input from the input unit 15 in accordance with instructions from the data processing unit 13.

  The operation unit 18 is used to perform various operation inputs, and includes a character determination unit 181, a document determination unit 182, a sending unit 183, a return unit 184, a selection unit 185, and a determination unit 186. As illustrated in FIG. 2, the units 181 to 186 of the operation unit 18 are configured with buttons on the mobile communication device 10.

  As described above, the character determination unit 181 is for making it clear that the input of one character has been completed and allowing the next new character to be input. The document confirmation unit 182 is for confirming the content of the document input from the input unit 15. That is, the data input from the input unit 15 is converted into Braille by the data processing unit 13 and displayed in braille on the display unit 16 and is output as audio from the speaker 17. In this state, the input data is in an unconfirmed state. Thus, post-processing such as transmission of input data or the like cannot be performed. When the document confirmation unit 182 is pressed after data is input, the input data can be post-processed.

  The sending unit 183 and the returning unit 184 are for displaying the content displayed on the display unit 16 by moving forward or backward. When the sending unit 183 is pressed by the user, the sending unit 183 outputs the pressing information to the data processing unit 13. Then, the data processing unit 13 determines whether or not the next character is present in the document displayed on the display unit 16. If the next character is present in the document, the data processing unit 13 displays the next character. Let the part 16 express braille corresponding to the next 20 characters. On the other hand, if the next character does not exist in the document, the data processing unit 13 determines that the document ends and does not perform the character sending process. The return unit 184 also performs a document forward return process in the same manner as the sending unit 183.

  The selection unit 185 selects a transmission / reception mode and a command such as transmission. The determination unit 186 is for determining the mode, command, etc. selected by the selection button 185, and for switching modes and executing various commands.

  Next, a method for using the mobile communication device 10 according to the present embodiment will be described.

  When receiving mail, the user selects the reception mode with the selection unit 185 and determines the mode with the determination unit 186. The data processing unit 13 stores the received mail document in the storage unit 14 when a signal indicating an incoming mail is input from the receiving unit 122. The data processing unit 13 converts characters constituting the mail document into Braille with reference to the dictionary 141 and the Braille conversion table 142, and displays 20 characters from the beginning of the conversion result (Braille information) on the display unit 16. . Thereafter, in response to an operation of the sending unit 183 or the returning unit 184 by the user, the display character is forwarded or rewinded. Further, the content of the received mail document is output from the speaker 17 by voice.

  When transmitting mail, the user selects a transmission mode with the selection unit 185 and determines the mode with the determination unit 186. The user inputs a destination mail address and transmission contents from the input unit 15. At this time, as described above, the input content is displayed on the display unit 16 and is output as sound from the speaker 17, and the subsequent process cannot be performed unless the user presses the document determination unit 182. Therefore, in order to complete the input and perform the transmission process or the like, the user must press the document confirmation unit 182 to confirm the input content. When the document confirmation unit 182 is pressed to confirm the input content, the input content can be transmitted. Then, by selecting a transmission command by the selection unit 185 and determining the command by the determination unit 186, mail transmission is executed.

  According to the embodiment described above in detail, the following excellent effects can be obtained.

  In the mobile communication device 10 according to the present embodiment, mail received from the outside can be displayed in braille on the display unit 16. As a result, even a visually impaired person can check the contents of the received mail.

  In this embodiment, since it can input from the touch panel 151, it becomes possible to perform input work easily. In particular, in the present embodiment, braille or characters can be input from the touch panel 151 by using the touch pen 152. Thereby, even a person with visual impairment can easily perform input work.

  In this embodiment, since the speaker 17 is provided, even a visually handicapped person who cannot read Braille can check the contents of the received mail and the contents of the input document. Also, for those who can read Braille, it is possible to perform double confirmation by confirmation by Braille and confirmation by voice.

  In this embodiment, a document confirmation unit 182 is provided, and an operation subsequent to the input can be performed only after the document confirmation unit 182 is pressed. For this reason, the user can check the input content displayed on the display unit 16 and be able to transmit the input content. As a result, it is possible to suppress erroneous input of transmission contents due to an input error and transmission to an erroneous destination.

  In the above embodiment, the content of the received mail and the content of the input data are output only in braille display on the display unit 16, but sound output from a speaker may also be performed.

  In the above embodiment, the input from the touch panel 151 is determined by pressing the character determination unit 181 every time one character is input. However, the input may be determined for each of a plurality of characters. In addition, the input from the touch panel 151 may be not only braille input but also normal character input.
