Abstract
The utility model patent relates to a kind of electronic braille book, and it is comprised of touch-screen and main frame two parts.Petting Area is installed and is highlighted cell array.Highlight unit and be comprised of cylindrical piezoelectric ceramic block and connected cylindrical touch head, the both positive and negative polarity of piezoelectric ceramics block is connected with main frame by wire.Main frame is exported respectively " high voltage " and " low-voltage " to highlighting accordingly unit according to " 0 " and " 1 " of the data binary number of output." high voltage " protrudes the touch head that highlights unit, and " low-voltage " makes to highlight the touch head depression of unit.Blind person reads electronic braille book by finger touch.The advantage of the utility model patent is cheap, with less volume, stores a large amount of braille books.
Description
Technical field
The present invention relates to a kind of electronic braille book.
Background technology
At present, there is people with visual impairment 1,291 ten thousand people in China.Blind life 65,081 people in school, wherein accept blind person 60,163 people of elementary education, account in 92% of the blind life in school, and the blind person who accepts higher education only account in 1% of the blind life in school.Blind person's ratio of accepting the education is on the low side, and wherein one of most important reason is exactly that China's information and cultural exchanges Studys about construction of no-obstacle environment fall behind, and blind person does not enjoy social construction achievement coequally, and especially blind person's read resource is not enough.Chinese braille publishing house is the annual braille books and periodicals kind more than 1,000 of publishing at present, 320,000 of circulation, and one of average 40 blind person in the whole nation, enjoy per capita every year 40 kinds of publications with person of good sense and compare, and the braille publishing thing that blind person reads is serious scarcity.
Braille is the letter symbol that salient point combines, more a little less or salient point change in location will form another braille word, therefore the work of braille publishing thing is translated, proofreaded, is made into common bright eye hard copy publication is wasted time and energy, and braille publishing thing printing process is complicated, the cycle is long, cause blind person to read braille publishing thing and obtain content information and seriously lag behind bright word publication by touching.Improve blind person's level of education, colligate diathesis and ability, in-depth blind person participates in the degree of social construction, allows blind person become and builds the indispensable strength of society, and it is to improve blind person's reading environment at all, extensively promote blind person and read, realize culture and information interchange accessible.
Summary of the invention
The utility model patent relates to a kind of electronic braille book, and it is comprised of touch-screen and main frame two parts.Petting Area is installed and is highlighted cell array.Highlight unit and be comprised of cylindrical piezoelectric ceramic block and connected cylindrical touch head, piezoelectric ceramics block is connected to positive and negative electrode, by wire, is connected with main frame.Main frame is exported respectively " high voltage " and " low-voltage " to highlighting accordingly unit according to " 0 " and " 1 " of output data binary number." high voltage " protrudes the touch head that highlights unit, and " low-voltage " makes to highlight the touch head depression of unit.Blind person reads electronic braille book by finger touch.
The advantage of the utility model patent is cheap, with less volume, stores a large amount of braille books.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of touch-screen.
Label declaration: 1 panel, 2 touch heads, turn over key before 3, turn over key, 5 piezoelectric ceramics blocks after 4.
Embodiment
1. basic comprising
Electronic braille book is comprised of touch-screen and main frame two parts.
Touch-screen profile is rectangular faceplate (1), positive minute key zone and Petting Area.
Key zone before installing, turn over key (3) and after turn over key (4) and be used for controlling page turning forward and page turning backward.Petting Area is installed and is highlighted cell array.Highlight unit and be comprised of cylindrical piezoelectric ceramic block (5) and connected cylindrical touch head (2), piezoelectric ceramics block (5) is connected to positive and negative electrode, and electrode is connected with main frame output control part.Highlighting unit lines up 3 * 2 subarray and is used for showing a Braille.The array that 3 * 2 subarray of several rows, some row is lined up forms the cell array that highlights of Petting Area.
Main frame comprises that data store is divided and output control part.
Data store is divided for storing the read data of books for the blind.Read data is with the binary number representation of grouping, and every group of binary number equates also corresponding one by one with the number that key zone highlights unit.Output control part is exported respectively " high voltage " and " low-voltage " to the unit that highlights of response according to " 0 " of binary number and " 1 ".
2. the course of work
Braille book is divided into some groups of binary numbers according to highlighting the arrangement of unit at Petting Area, and each group is for the demonstration of electronic braille book one page.Read after each page data, control section is exported respectively " high voltage " and " low-voltage " to the unit that highlights of response according to " 0 " and " 1 ".The touch head (2) that highlights unit that receives " high voltage " protrudes, and receives touch head (2) depression that highlights unit of " low-voltage ".Blind person reads electronic braille book by finger touch.
The physiology characteristic of application on human skin has determined sense of touch suffered restriction on image perception, and wherein the threshold value of distinguishing of 2 is an important parameter.Finger two-point discrimination threshold value is approximately 2.5mm, and in this distance, with 2 interior points, people's great majority can be thought a point, and this parameter is equivalent to the resolution of sense of touch, highlights unit and arranges according to this resolution at the arrangement pitches of Petting Area.
