I-alfabhethi ye-Braille iyisistimu yokurekhoda eqondile esetshenziselwa izincwadi, imibhalo, imali kanye nezinye izihloko zabantu abamboni nabangaboni kahle. Ngenxa yezibonisi ezakhiwe ngesisekelo se-Braille, izimpumputhe zingasebenzisa amakhompyutha kanye nezinye izindlela zomboni. Ungarekhoda ngamadivaysi akhethekile, njenge-notebook ephathekayo noma ikhibhodi ye-braille.
I-alfabhethi ye-Braille ibizwa ngokuthi umdali wayo - umFulentshi uLouis Braille, oye waphambuka ebuntwaneni ngenxa yokuhlukumezeka. Ngo-1824, eneminyaka engu-15 ubudala, wahlakulela leli fayela ukuze amaphephandaba amaFulentshi abe ngcono kwezobuchwepheshe bezempi bokufunda ebusuku. Ukushicilelwa kwalesi simiso, okwathi kamuva kwafaka inothi yombhalo, kwenzeka ngo-1829. Uhlelo lwesibili, olwanyatheliswa ngo-1837, lwaluyisimiso sokuqala sokuqopha kanambambili .
Ama-alphabet for the blind are a sign that has the form of block blocks (cells) with points convex. Inombolo nendawo yala maphuzu zihlukanisa incwadi eyodwa kusuka kwenye. Njengoba i- Braille ibhalwe phansi kwezinhlelo ezibhaliwe ezikhona, umyalo nenombolo yabalingiswa ziyahlukahluka kuye ngolimi. Ngenxa yesofthiwe, ekwazi ukuveza umsindo wombhalo, ukusetshenziswa kwefonti kuye kwehla kakhulu. I-ABC ye-Blind iyaqhubeka nokudlala indima enkulu ekuthuthukiseni amakhono okufunda abantwana abangaboni, nokufunda nokubhala nokubhala kuvumela ukwandisa izinga lomsebenzi phakathi kwabantu abakhubazekile.
Ifonti yeBraille yayisekelwe emasotini, okuthiwa "incwadi yobusuku" eyenziwe nguCharles Barbier mayelana nesidingo sokuxhumana ebusuku ngaphandle kokukhanga isitha ngosizo lwezwi noma ukukhanya. Esikhathini sesistimu ye-Barbier, iqoqo lama-convex angu-12 alingana nomunye wezingoma ezingu-36. Le ndlela inqatshelwe ibutho, ngoba laliyinkimbinkimbi kakhulu empi. Ngo-1821, uBarbier wavakashela iRoyal Institute of the Royal eParis, lapho ehlangana noLouis Braille. I-Braille ibone ukushiyeka okubili okuphawulekayo kwalesi sici. Okokuqala, izimpawu zihambisana kuphela nemisindo, ngakho-ke ayikwazanga ukubonisa isipelingi samagama. Okwesibili, izimpawu ezivela kumaphuzu angu-12 e-convex zazikhulu kakhulu ukuba zingaboni ngokuthintana, ngaphandle kokuhambisa iminwe yabo, okuyinto eyashesha kakhulu inqubo yokufunda. I-alfabhethi ye-Braille iguqulwa, lapho amangqamuzana amaphoyinti angu-6 ahambisana nezinhlamvu ngabanye zezinhlamvu.
Ekuqaleni, ifonti ye-Braille yayihlanganisa kuphela izinhlamvu zezinhlamvu zamaFulentshi, kodwa maduzane kunezifinyezo eziningi, izifinyezo ngisho nama-logogram owenza ukusetshenziswa kwesistimu kube lula kakhulu. Namuhla i-alfabhethi ye-Braille ingcono uhlelo lokubhala oluzimele lwempumputhe, kunokuba ikhodi yokupelomagama yamagama. Kunezigaba ezintathu zefonti. Iyokuqala isetshenziswe yilabo abaqala ukufunda nge-Braille, futhi iqukethe izinhlamvu nezimpawu zokubhala. Okuvame kakhulu yizinga lesibini, lapho kunezifinyezo ezikuvumela ukuthi ulondoloze isikhala ekhasini. Ngokuvamile, ungathola iveli lesithathu, lapho amagama onke efinyelelwa khona ezincwadini ezimbalwa noma ebhaliwe usebenzisa izimpawu ezikhethekile.
