Technologies tab tom txhim kho tsis yog sai, tab sis nrawm. Dab tsi yog ib zaug suav tias yuav luag ib qho txuj ci tseem ceeb tam sim no siv txhua hnub. Kov cov keyboards thiab cov ntxaij vab tshaus tau dhau los ua ib feem ntawm lub neej niaj hnub. Cov khoom siv no yog lub teeb thiab siv tau yooj yim, muaj lub neej ua haujlwm ntev thiab muaj kev ntseeg siab - tsuas yog tsis muaj cov khoom siv uas tuaj yeem tawg. Touchscreen
keyboard (thaum tsim ntau lawm) muaj tus nqi qis, vim tsis tas yuav siv cov pwm cam thiab siv sijhawm thiab tib neeg cov peev txheej ntawm kev sib dhos. Qhov zoo ntawm cov thev naus laus zis no suav nrog qhov tseeb tias cov cuab yeej zoo li no yog kev tu cev - tsis muaj qhov twg los khaws cov plua plav thiab av. Tsis tas li ntawd, cov keyboard kov tsis ntshai cov kua uas nchuav (uas yog qhov tseem ceeb heev rau cov neeg uas siv sijhawm ntau ntawm lub computer thiab feem ntau noj thiab haus "ntawm qhov chaw"). Ib lub cuab yeej ntawm hom no tuaj yeem muaj tus lej ntawm cov nyees khawm, ib qho kev saib thiab teeb tsa. Nws tuaj yeem tsim rau hauv ib qho khoom siv: cov cuab yeej siv, kev ruaj ntseg tshuab, ATMs, instrumentation, thiab lwm yam.
Tab sis ib txwm,muaj downsides. Ua ntej ntawm tag nrho cov, nws yog hais tias muaj teeb meem nrog loj ntau lawm. Muaj kev txhim kho, tab sis cov cuab yeej no tsis tau muag ntau. Qhov tseem ceeb tshaj plaws uas yuav tsum tau siv tshuab thev naus laus zis uas yuav tso cai
txheeb xyuas qhov kov ntawm lub ntsiab lus kov, uas yog kim, thiab, pom meej, yog txoj haujlwm tsis txaus ntseeg niaj hnub no (tsawg kawg rau tam sim no). Kuj tseem muaj teeb meem nrog software, uas yuav tsum ua kom tsis muaj teeb meem ua haujlwm. Qee cov neeg siv kwv yees cov teeb meem hauv kev siv cov keyboards zoo li no: nws yuav tsis yooj yim rau kev ntaus qhov muag tsis pom kev, uas tsis zoo li yuav txaus siab rau cov tswv ntawm cov txuj ci zoo li no. Yog li, ntawm ib sab, kov cov keyboard yooj yim thiab siv tau, tab sis ntawm qhov tod tes, nws tsa ntau cov lus nug.
Txoj Cai Ua Haujlwm
Kev ua haujlwm ntawm cov khoom siv kov yog ua raws li kev siv cov sensors tshwj xeeb ntawm tus qauv tsim tshwj xeeb. Raws li cov ntsiab lus rhiab heev, cov ntaub qhwv sib txuas yog siv, sib cais los ntawm qhov sib txawv me me. Tus naj npawb ntawm cov sensors sib raug rau tus lej ntawm cov yuam sij. Thaum koj kov ib qho chaw tshwj xeeb nrog koj tus ntiv tes, qhov muaj peev xwm zoo li qub nce ntxiv rau nws, raws li qhov tshwj xeeb Circuit Court tsim lub teeb liab qhia tias lub sensor tau tshwm sim.
Cov keyboard kov yog qhov tsis ntseeg tias yog cov cuab yeej siv thev naus laus zis ntau dua li ib txwm thawb-khawm units, tab sis txog tam sim no nws tseem tsis tau txais kev siv kom raug. Tsis yog, nws yog siv hauv qee cov khoom siv (piv txwv li, hauv cov khoom siv hauv tsev), tab sis, raws li txoj cai, nws tsis muaj ntau tshaj li kaum os.(los yog li) cov yuam sij. Lub computer keyboard li ib txwm muaj txog ib puas ntawm lawv, uas, pom tau tias, yog qhov nyuaj rau cov neeg tsim khoom. Muaj twb tau tsim tawm, tab sis qhov teeb meem tsis tau mus txog loj ntau lawm. Tab sis thev naus laus zis tau nce mus, thiab, tej zaum, tom qab ib ntus, cov khoom siv kov yuav twb muaj lawv cov kev xaiv ntawm cov keyboard. Lub sijhawm no, peb tsuas yog xav seb nws yuav yooj yim lossis tsis, thiab suav cov txiaj ntsig theoretical.
