Description
Technical field
The present invention relates to Computer Language Processing, educational facilities technical field, specifically, being related to a kind of Chinese braille touching reading
Device.
Background technology
According to statistics, China about 13,000,000 people suffer from visual disabilities to a certain extent, wherein about 5,500,000 is blind
People, 7,500,000 people suffer from low visual acuity.In general, blind person by touch be printed upon the concave-convex braille on brown paper obtain knowledge and
Information.However, traditional books printed in braille quantity is few, single varieties, resource lag, information content is small, and volume heaviness, not Portable belt,
So that traditional braille book much can not meet the reading requirement of blind person.Therefore for blind person design it is a meet their use need
Chinese braille touching reading device that is asking and being connected with computer, network is very important.
Through the retrieval to the prior art：
The Chinese invention patent of publication number CN 1591414A discloses a kind of automatic translation conversion method of Chinese braille,
It describes from inputting Chinese characters string, to string segmentation, then to judging whether character string is punctuation mark or ASCII character word
Symbol etc., the Braille by generation to the last externally exports.It essentially describes and turns from Chinese character string to Braille
Change process, in the form of text be shown as final result rather than obtained from haptic apparatus display result.
The Chinese invention patent of publication number CN 1323003A is mentioned to compareing for braille ASCII character and Braille code
Table since ASCII character is mainly a set of computer code's system according to the Latin alphabet, is mainly used for showing current english and other
Western-European languages.Therefore it is not preferable conversion method for the Chinese character based on Pinyin Input.
The Chinese invention of Application No. CN00103236.4 is related to a kind of Braille generation method, which also relates to
Braille alphabet reading device and typing apparatus.The Braille alphabet reading device touch device operation principle be：It is added at coil connectors both ends
Electric signal, then coil magnetic field can be generated in hollow frame, movable inner core can be made to move upwards under the influence of a magnetic field, due to touch
It gets to know and is fixed together with movable inner core, then hollow frame will be protruded by touching head.This method is mainly using electromagnetic principle come real
The gravity of the up and down motion of existing movable inner core, the resistance and movable inner core generated using magnetic force with positioning protrusion and touch head is supported
Disappear, make movable inner core and touch static to get off.However this method and unstable, the device does not point out hollow frame first
Selected material if material selection is improper, is on the one hand likely difficult to generate sufficiently strong magnetic field to attract movable inner core, the opposing party
Face after a loss of power may not demagnetization at once, this correctness that can be shown to follow-up braille has a significant impact.In addition, the device is not
Enough to stablize, after powered up, which has reached the balance of power, so when human hand is touched when on the touch device, additional touch
Power can break the balance of power, and the display effect of braille is made to have a greatly reduced quality.
