Neeg kho tshuab cov ntsiab lus [ edit ]

Lub hauv paus ntawm lub yeeb yam ua kom muaj zog tshiab feem ntau muab cov xim braille txhais ua ke. Muaj, lub tswv yim yog ua los ntawm ob tug poob lawm ntawm plaub lub lag luam nyob rau txhua sab, thaum tso zis yog ntawm ib tug refreshable dig muag zaub muaj ib tug kab ntawm electro-mechanical cim hlwb , txhua tus uas muaj peev xwm tsa los yog txo ib tug ua ke ntawm yim round-tipped pins . Lwm yam variants nyob uas siv ib tug pa QWERTY keyboard rau cov tswv yim thiab dig muag pins rau tso zis, raws li zoo li cov tswv yim nkaus xwb thiab tso zis-tsuas pab kiag li lawm.

Nyob rau ib co ua qauv rau txoj hauj lwm ntawm lub cursor yog sawv cev los ntawm vibrating lub tsuas me me, thiab ib co qauv muaj ib tug mus txuam nrog txhua cell kom tshem tau cov cursor rau cov uas cell ncaj qha.

Lub mechanism uas seb puas tsimnyog tau cov dots siv cov piezo nyhuv ntawm ib co muaju, xwv kom lawv nthuav thaum ib tug voltage yog thov mus rau lawv. Xws li siv lead ua txuas mus rau ib qib, uas nyob hauv kev tshwm sim nce qhov teeb meem. Muaj tau ua ib qho siv lead ua rau txhua qhov ntawm daim duab, piv txwv li yim ib cim.

Vim tias tsis muaj teeb meem ntawm kev ua kom pom tau tias yuav ua rau txhua hnub hnav thiab tu dua, cov lus qhia no tseem kim. Feem ntau, tsuas yog 40 los yog 80 dig muag hlwb muaj tso tawm. Cov qauv nruab nrab ntawm 18 thiab 40 lub hlwb muaj nyob rau hauv qee cov ntawv cim ntiag tug.

Software [ edit ]

Lub software uas tswj cov zaub no hu ua ib tug kev tshuaj ntsuam nyeem ntawv . Nws sau cov ntsiab lus ntawm qhov kev tshuaj ntsuam los ntawm cov operating system , converts nws mus rau hauv dig muag cim thiab xa nws mus rau cov zaub. Cov nyeem nyeem ntawv rau graphical operating systems yog qhov nyuaj, vim hais tias cov ntsiab lus zoo li qhov rais los sis cov slidebars yuav tsum tau txhais thiab piav nyob rau hauv daim ntawv. Niaj hnub nimno operating systems feem ntau yog muaj ib tug Daim ntawv thov Programming Interface los pab tshuaj ntsuam cov txawj nyeem ntawv tau cov ntaub ntawv no, xws li UI Automation (UIA) rau Microsoft lub qhov rais , voiceover rau OS X thiab iOS , thiab saib-SPI rau GNOME .

Yav tom ntej designs [ edit ]

  • Ib tug yam-log Braille zaub yog tsim nyob rau hauv 2000 los ntawm cov teb chaws lub koom haum ntawm Standards thiab Technology (NIST) thiab lwm ntawm lub Leuven University nyob rau hauv Belgium. [1] Ob log yog tseem nyob rau hauv tus txheej txheem ntawm commercialization. [ Meej yuav tsum tau ] Nyob rau hauv cov chav nyob, dig muag dots yog muab tso rau ntawm ntug ntawm ib tug spinning log , uas tso cai rau tus neeg siv yuav nyeem tsis tu ncua nrog ib tug ruaj ruaj ntiv tes thaum lub sij hawm cov log spins ntawm ib tug xaiv ceev. Cov dig muag dots yog teev nyob rau hauv ib tug yooj yim PP-style zam raws li lub dots rau hauv lub log kiv dhau los ib tug nyob ruaj ruaj Actuator uas teev cov dig muag cim. Yog li ntawd, kev tsim kev lag luam tsis zoo heev thiab cov lus teb rov qab ua ke, thaum lub sij hawm tseem ceeb, yuav tsum tsis tshua kim dua cov lus qhia me me.

  • Cov qauv tsim kom muaj lub braille computer saib tau muaj patented tab sis tseem tsis tau ua. [2]

  • Ib tug tag nrho cov nplooj ntawv dig muag zaub nrog 1,000 hlwb (25 kab ntawm 40 hlwb) tau tsim nyob rau hauv 2015 los ntawm cov Tactisplay Corp. [3] Nrog tag nrho 12,000 pixels teeb nyob rau hauv 120 * 100, nws yuav qhia tej yam BANA tshaj dig muag nraaj page nyob rau hauv 8 lub vib nas this. Qhov no video qhia tau hais tias lag luam ntawm lub ntaus ntawv.

  • Tactile yog ib tug tiag tiag-lub sij hawm ntawv nyeem-rau-dig muag translation ntaus ntawv, tam sim no nyob rau hauv txoj kev loj hlob ntawm lub Massachusetts koom haum ntawm Technology . [4]
