Digitizer: nws yog dab tsi, cov kev khiav hauj lwm hauv paus ntsiab lus, tau

Niaj hnub nimno kev ua lag luam ciaj nrog ntau yam ntawm gadgets thiab hluav taws xob khoom. Consumer xaiv mas nyob ntawm lub npaj siv ntawm lub pab kiag li lawm. Rov qab nyob rau hauv lub 70s ntawm lub xeem caug xyoo nyob rau hauv lub coj mus muag kheej muaj ib tug txuj ci tseem ceeb ntawm technology - digitizer. Yuav ua li cas nws yog li cas thiab nws yog hnub no paub, alas, tsis txhua leej txhua tus. Sim kom to taub.

txog koj ntaus ntawv

Txawb ub txawb elaborate kev cov ntsiab lus uas, cov digitizer yuav muab txhais li ib tug graphics ntsiav tshuaj, uas converts npaj txhij, ntawv los yog vector duab rau hauv ib cov hom ntawv. Tab sis tsis txhob xav yuam kev rau nws nrog li ib txwm scanner.

Digitizer muaj ib tug kov screen (tiag tiag ntsiav tshuaj) thiab yog nqus ib tug ntaus ntawv (cwj mem, stylus, cursor, thiab li ntawd.). Ua hauj lwm rau xws li ib tug ntaus ntawv yuav haum nyob rau hauv ob kauj ruam:

• kev tso kawm ntawm cov duab ntawm qhov screen;
• kho cov coordinates ntawm tus cwj mem los yog tus cursor rau lub ntsiav tshuaj.

Nyob rau hauv cov ntaub ntawv ntawm animation, tsuas tsim nyog kev txawj ntse ntawm lub stylus.

hom

Tswv yim technology ntawm cov duab ntaub ntawv nyob rau hauv tus cwj mem interfaces yog cov sib txawv. Nyob rau hauv no hais txog, muaj tsib yam ntawm pab kiag li lawm:

1. Acoustic. Qhov no yog ib tug ntawm cov thawj duab ntsiav tshuaj. Hais tias paints cwj mem generated qhov thiaj li hu ua sonic txim uas captures screen microphones. Yog li, tus ntaus ntawv txiav txim seb tus coordinates ntaub ntawv. Ib tug loj shortcoming ntawm lub chaw ua hauj lwm nrog cov ntsiav tshuaj yog hais tias cov tswv yim ntawm cov ntaub ntawv twb ua nyob rau hauv tsis silence, raws li acoustic cuam yuav lwj hauv daim duab. Qhov no hom ntawm digitizer yog lub npe hu rau ua ib tug xov tooj ntawm pab kiag li lawm nyob rau hauv ib lub npe txim ntsiav tshuaj.
2. Electromagnetic. Tus ntaus ntawv ntawm cov ntsiav tshuaj yog ib tug me ntsis yooj yim dua thiab ntau tsim tshaj yav dhau los cov qauv. Nyob rau hauv qhov kev tshuaj ntsuam nto nyob hlau mesh, faint radiating electromagnetic Pib ntsais koj teeb. Perot tau ntes tau lawv, thiab thiaj li muaj yog ib tug kho nws qhov chaw nyob. Qhov no muaj xws li qeb pab kiag li lawm RAND ntsiav tshuaj, uas nyob rau hauv 1964.
3. Passive cursor. Peb siv cov ntsiab cai tib yam ntawm electromagnetic induction, nyob rau hauv cov pab kiag li lawm xwb hlau netting thiab kis Pib ntsais koj teeb, thiab yuav tau txais lawv. Kev nkag mus kawm ntaub ntawv no tshwm sim thaum nias tus cwj mem thiab uas tsis yog-hu txoj kev. Yog nqus tau ntaus tsis yuav tsum tau lub hwj chim. Nws yog ib tug kev txhob. Ib qho piv txwv ntawm xws li ib tug ntaus ntawv tej zaum yuav ua tau ib tug graphics ntsiav tshuaj Wacom.
4. Active cursor. Nyob rau hauv no ntaus ntawv ntawm lub teeb liab generator yog tsiv mus rau tus cwj mem. Raws li, nws xav tau kev pab khoom noj khoom haus. Cov hluav taws xob Pib ntsais koj teeb muab dlaim phaj dluab tshaj electromagnetic. Qhov no qeb ntawm pab kiag li lawm sawv cev ntawm lub tuam txhab FinePoint Nrhav.
5. Kov digitizer - ib tug niaj hnub ntaus ntawv. Nyob rau hauv qhov chaw ntawm lub screen lawv yog cov tswj nyob ntawm tej. Lawv sib cais los ntawm ib tug nyias insulator. Nyob rau hauv lub siab ntawm lub stylus nyob rau conductivity hloov. Sensitive screen thiab rhiab rau lub coordinates, thiab lub hwj chim ntawm nqus ib siab ntaus ntawv. Ib txhia tshuab tso cai rau koj mus digitize peb-seem.

Ntawm cov hoob kawm, qhia ntau txog yuav tsum tau muab tso rau hauv cov yam ntxwv ntawm sensor pab kiag li lawm. Raws li paub qhov txawv PP hom ultrasonic, magnetic thiab laser-kov screen digitizer. Tus thawj yog tsawg leej thiab txhim khu kev qha, txij li thaum cov kev ceev ntawm lub suab yog ncaj qha nyob rau hauv lub kub, cua siab thiab lwm yam ambient phenomena.

Sib Nqus digitizers ntau yog, tab sis yog nkag mus hlau khoom uas ze (tog zaum, computers, txawv kho vajtse). Tej cuam yuav ua rau distortion ntawm daim duab.

Thaum kawg, laser digitizers yog cov feem ntau muaj tseeb, tab sis kim heev niaj hnub no. Txawm li cas los, cov pab kiag li lawm muaj ob peb cov kev txwv. Lawv yuav ua tsis tau digitized cov khoom uas paab, kaj los yog concave nto.

Nyob rau hauv tas li ntawd, hnub no txoj kev ua lag luam koj yuav nrhiav tau kev yeem thiab saj zawg zog digitizers. Cov yav tas twb nyob rau hauv 1994. Lawv yog cov khaub-ncaws nyias, compact rau kev thauj mus los. Khoom siv fais fab nyob rau hauv lawv muaj peev xwm yuav yog ua-nyob rau hauv los yog sab nraud.

xaiv

Nws yog ib qho tseem ceeb rau koj nco ntsoov thaum xaiv ib digitizer hais tias nws yog ib tug loj thiab kim ntaus ntawv, uas yuav tsum tau sai li sai tau haum rau tus neeg uas yuav tsum tau ntawm tus neeg siv. Nws yog tsim nyog los phim lub puab txheej ntseeg yam ntxwv. Zoo tsav tsheb, pab txhawb rau cov kev tsim nyog software thiab ib ke taw ntaus ntawv - cov no yog cov peb tug ncej uas yuav tsum tau raws li kev xaiv ntawm lub buyer. Niaj hnub nimno tuam txhab uas muag-cov thawj coj nyob rau hauv qhuav ntawm digitizers rau ntse heev yog cov kev ua lag luam. Hitachi, CalComp, Wacom. Lawv tsim graphics ntsiav tshuaj nrog ib tug txawv interface, operating system, ib tug kab pheeb ces kaum.

Peb kuj yuav tsum tham txog txoj cai kiag li lawm.

cursors

Ib tug tsim tej kev cai (los yog kab nqus) pab kiag li lawm sawv cev los ntawm ob hom: cov cursors thiab plaub. Tus thawj yog heev nrov. Nyob ntawm seb tus qauv, lawv yuav ua tau 4, 8, 12 los sis 16 lub lag luam. Txawm li cas los, ib co manufacturers (xws li, ib tug Graphics) ntxiv ib tug ntau khawm - "tseem ceeb tshaj plaws." Tab sis, raws li kev xyaum qhia, cov yooj yim cov ntaus ntawv, li ntawd, nws yog ib ntau yooj yim, ntau txhim khu kev qha thiab ntau nrov ntawm cov neeg siv. Yog li ntawd, pab kiag li lawm nrog plaub nyees khawm muaj ntau kev vam meej dua lawv cov advanced counterparts. Tej qauv no yog muaj los ntawm CalComp.

Raws li kws txawj, tus cursor xaiv yuav tsum tau txuas tsis tau tsuas yog los tejzaum thawj coj thiab tus xov tooj ntawm cov nyees khawm, tab sis kuj muaj feem rau cov siv cov kev pab cuam. Nyob rau hauv cov ntaub ntawv no nws yog tsim nyog hais lus ntawm AutoCAD.

Plumage

Cov pab kiag li lawm pom tau hais tias yuav yooj yim dua thiab rhiab. Lawv muab tsuas yog ib, ob los yog peb cov nyees khawm thiab hnov mob rau lub siab caj npab.
