Description
Technical field
The present invention relates to Computer Language Processing, educational facilities technical field, concrete, relate to a kind of Chinese braille and touch read apparatus.
Background technology
According to statistics, nearly 1,300 ten thousand people of China suffer from visual disabilities to a certain extent, and wherein nearly 5,500,000 blind persons, 7,500,000 people suffer from low visual acuity.Usually, blind person obtains knowledge and information by touching the concavo-convex braille be printed on kraft.But traditional books printed in braille quantity is few, kind is single, resource is delayed, quantity of information is little, and volume is heavy, not Portable belt, makes traditional braille book can not meet the reading requirement of blind person far away.Therefore for blind person design a meet their user demand and the Chinese braille that can be connected with computer, network touch read apparatus and be very important.
Retrieval through to prior art:
The Chinese invention patent of publication number CN1591414A, disclose a kind of automatic translation conversion method of Chinese braille, describe from inputting Chinese characters string, arrive string segmentation, arrive again and judge whether character string is punctuation mark or ASCII character character etc., the Braille of generation is externally exported to the last.Essentially describe the transfer process from Chinese character string to Braille, in the form of text be shown as net result instead of from haptic apparatus obtain show result.
The Chinese invention patent of publication number CN1323003A, is mentioned to the table of comparisons of braille ASCII character and Braille code, because ASCII character is mainly according to a set of computer code's system of the Latin alphabet, is mainly used in display current english and other Western-European languages.Therefore be not desirable conversion method for the Chinese character based on Pinyin Input.
Application number is the Chinese invention of CN00103236.4, relates to a kind of Braille generation method, and this patent also relate to Braille alphabet reading device and typing apparatus simultaneously.The principle of work that this Braille alphabet reading device touches device is: add power on signal at coil connectors two ends, then coil can produce magnetic field in hollow frame, movable inner core can be made to move upward under the influence of a magnetic field, because touch head and movable inner core are fixed together, then touch head and just can protrude hollow frame.The method mainly utilizes electromagnetic principle to realize moving up and down of movable inner core, the resistance utilizing magnetic force and positioning convex to produce and movable inner core and touch the counteract gravity forces of head, makes movable inner core and touch static to get off.But this method is also unstable, first this device does not point out material selected by hollow frame, if Material selec-tion is improper, may be difficult to produce enough strong magnetic field to attract movable inner core on the one hand, on the other hand after a loss of power may not demagnetization at once, this can have a significant impact the correctness that follow-up braille shows.In addition, this device is stable not, and after powered up, this device reaches equilibrium of forces, so when staff touches on this touch device, additional touch force can break equilibrium of forces, makes the display effect of braille have a greatly reduced quality.
