Description

Voice-braille terminal for e-books {Voice-Braille Terminal for Electronic Book}

The present invention provides a method for freely and conveniently obtaining various books and information materials required by individuals in order to prevent the visually impaired from being alienated in an information society that develops equally well with the general public. In addition, the visually impaired to reduce the inconvenience of using the general electronic documents.

The voice-braille terminal is a system for outputting braille or voice content of an e-book through a special terminal. Here, e-books are all electronic media, including off-line CD-Rom, cassette tape or on-line Internet and PC communication. It is a method of publishing in Braille and voice using W and SST.

The current supply of e-books can be done by downloading digital files through communication networks such as internet bookstores, digital libraries, and kiosks, or by using distribution networks that people can easily obtain, such as existing bookstores, 24-hour convenience stores, gas stations, etc. (Memory Card), MD (Mini Disk), CD-ROM, etc. can be mounted in the terminal for reading.

Until now, people with visual impairments borrowed braille books and recorded books mainly from braille libraries to obtain the necessary information.

A braille book is a book with a distinctive character that has a shape or dot on the page that the visually impaired person reads with a finger. Braille books are limited to only those who can read Braille among the visually impaired, and have disadvantages such as a small population, low purchasing power, high cost, and a large number of places. Braille books are considerably thicker than conventional books, and are difficult and expensive to reproduce and print in large quantities.

Recorded books are recorded by a reader and recorded on a tape or tape. Unlike in the case of face-to-face reading, a recorded book does not require a reader and can be reproduced and copied by using a tape. There is an advantage. And it has become an important reading means for the visually impaired who cannot read Braille. However, technical guidebooks and difficult-to-read contents are difficult to understand, they cannot feed back questions, and there are limitations to manual reading.

Therefore, in the case of recording books, which are lightly readable literature and the like, and which are highly specialized materials, it is preferable to use both braille books and face-to-face reading.

Accordingly, an object of the present invention is to provide a complex terminal capable of outputting voice and braille information of various types of information published in an electronic book.

A feature of the present invention for achieving the above object is a text recognition device (TTS device) for first converting (A) document data of an electronically published e-book into voice; An output device through a speaker; (B) a converter for converting document data into a combination ASCII code; A braille code converter for converting an ASCII code into a braille code; It characterized in that it comprises a braille output unit for receiving and outputting the braille code.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 is a system diagram according to the present invention, (A) for the audio output was configured as follows. The storage medium of the terminal is composed of a character recognition device 3 for converting text information of an e-book 1 such as a CD-ROM or a diskette into voice, and a speaker 6. At this time, the character recognition device 3 is a database 5 having voice data such as Korean, English, special characters, and the controller 4 for analyzing the syntax are connected to the central processing unit 2.

(B) For output to Braille, the configuration was as follows. It consists of an ASCII converter 11 for converting text of an e-book into an ASCII code, a braille code converter 12 for converting an ASCII code to a braille code, and an output unit 13 for receiving and outputting a braille code. In this case, the braille output unit 13 includes an electromagnet relay and a braille head portion 29 -A and 29 -B.

The central processing unit 2 receives control signals for each of the various optional function keys 7, 8, 9, 10 and moments of selection 110, 130, 200, 210, and the e-book 1, the character recognition device 3, and the ASCII code converter 11 By controlling the braille code converter 12, the user can freely select the contents of the data 1 of the e-book.

2 is a schematic diagram schematically showing an example of a voice-braille terminal according to the present invention.

As shown, the present voice and braille output terminal. The upper surface of the case is divided into a main braille output unit 30 and an auxiliary braille output unit 28, which is composed of a braille head (29-A, B) driven by electromagnetic. The main braille output unit 30 outputs the contents of the e-book in braille, and the auxiliary braille output unit 28 outputs page information at that time in a braille code. In addition, at the end of the main braille output unit 30, the enter button 31 formed with braille on the surface of the button 31 is installed, and after the user reads all the contents expressed in the main braille head 29-A, It is designed to go to the next line. When the enter button 31 is applied to the lower portion, the central processing unit 2 operates to output the next sentence in the contents of the e-book 1 to the braille head 29-A in braille. On the left side of the upper surface of the case, a power on / off switch 20 having a braille formed on the surface of the button, a voice-braille mode selection switch 21, a unit / page selection 22, and a numeric key 23 are provided.

The voice-braille mode selection switch 21 is a switch for selecting a braille book by voice or braille, and the unit / page selection switch (22) uses a numeric key (23) below to select a desired unit / page. As you type, you can jump to specific lessons and pages. These voice-braille mode selection switches 21, unit / page selection switches 22, and numeric keys 35 are directly connected to the central processing unit 2.

In addition, the page up-down button 32 is installed next to the main point output unit 30 so that the user can easily move to the next page before and after the content expressed in the main point braille section 29-A.

On the other hand, the side of the case is connected to the on-line e-books such as the Internet and PC communication to the voice-braille output, USB port 25 for downloading digital files, printer port 26, storage medium (1) A CD ROM drive 33 for in-CD ROM and a diskette drive 35 for inserting a diskette are provided. In addition, a power connection terminal 36 and an earphone terminal 37 for connecting with an external power source are provided.

3 is a flowchart schematically showing the configuration of a voice-braille terminal of the present invention. As shown, first, when the power of the voice-braille terminal 20 is turned on, the book list is displayed. When the user selects a list of e-books (110), the user reads the text information of the e-book data (120), determines whether the braille mode is On (130), and if the braille mode is not On (On), The voice is output through the speaker 160 through a text recognition device (TTS device) 150 for converting information into voice. If the braille mode is ON, the character information is converted to the ASCII code 170, the ASCII code is converted to the braille data 180, and it is determined whether or not the braille output command exists. Display 190. In addition, when the reader wants to read the e-book in another mode (200), the mode is selected again. If you want to read another e-book (210) and go back to the beginning of the list of e-book (100) selects the book timber (110).

As described above, the voice-braille complex terminal for the e-book of the present invention can freely and conveniently acquire various information materials required by the visually impaired by converting the e-book data into voice and braille. .
