Cov khoos phis tawm tau dhau los ua neeg ruaj khov nyob hauv peb lub neej txhua hnub uas tib neeg tsis quav ntsej rau tej yam tsis tseem ceeb xws li kev teeb tsa ntawm cov tsiaj ntawv ntawm cov keyboard. Tag nrho cov thoob lub ntiaj teb, cov neeg siv thiaj li hu ua QWERTY layout, uas tsis muaj dab tsi ua nrog tus niam ntawv.
Scholes tsab ntawv chaos
Cov tsiaj ntawv ntawm cov keyboard, thaum pom thawj zaug ntawm cov neeg tsis sau, raug teeb tsa hauv qhov tsis muaj kev ntxhov siab, tsis hais tus ntawv. Yog tias koj mus tob zuj zus rau hauv keeb kwm thiab nco qab qhov nyob deb ntawm 19th caug xyoo, thaum lub tshuab luam ntawv muaj, cov neeg tsim khoom tsis txhawj xeeb txog qhov chaw nyob ntawm cov ntawv ntawm cov keyboard, lawv xav txog cov txheej txheem ntawm kev xa cov ntawv rau daim ntawv. Tab sis tsis ntev lawv pom tias cov tsiaj ntawv tau pib zaws, lo ntawm txhua lwm yam los ntawm ntau zaus ntawm kev siv. Thiab nyob rau hauv 1868 kws tshaj lij lej Christopher Scholes txiav txim siab los nrog tsab ntawv sau tshiab. Nws tsuas tso cov ntawv uas nquag siv sib nrug ntxiv.
Los ntawm kev sau cov ntawv nyob rau hauv cov kab sib txawv, nws daws qhov teeb meem ntawm kev poob qis, thiab qhov no yog li cas cov ntsiab lus ingenious tau yug los - qhov hu ua QWERTY. Nws yog npe tom qab kab ntawv ntawm thawj kab ntawm keyboard. Nws yog qhov txheej txheem ntawm cov tsiaj ntawv uas ib txwm siv ntawm 98% ntawm cov keyboards hauv ntiaj teb.
McGurrin Txujci
Ntxiv mus, forensic stenographer Frank McGurrin txuas ntxiv txhim kho cov ncauj lus ntawm cov ntawv sau yooj yim, nws qhia qhov muag tsis pom kev kaum tus ntiv tes, uas tau txais qhov muaj koob npe.
Cov txheej txheem dig muag tau ua rau kom tsis txhob saib cov keyboard, tab sis kom ntaus nrog txhua tus ntiv tes (ntiv tes ntiv taw tau siv ntau zaus).
Kaum tus ntiv tes ua haujlwm ntawm cov ntawv sau ergonomic coj ntsuas kev nrawm mus rau qhov siab tshiab thiab nce cov khoom lag luam rau cov ntaus ntawv thiab cov neeg sau ntawv.
Ntau xyoo ntawm kev tshawb fawb hauv kev ua lej, cov kws tshawb fawb, stenographers tau sim txhim kho cov txheej txheem keyboard, nws yog qhov tseeb tias kev hloov tus ntawv ntawm cov tsiaj ntawv tsis yooj yim rau kev ua haujlwm nrog. Nqa tawm ntawm lawv cov kev ntsuas, lawv txhua tus, qhov tseeb, tuaj rau qhov kev nrhiav tau qhov yooj yim uas ua rau tib neeg lub neej yooj yim rau ntau pua xyoo tom ntej.
QWERTY keyboards yog li nrov thiab ergonomic tias lawv nquag siv los ntawm cov xov tooj txawb chaw tsim khoom niaj hnub no. Ntxiv rau, tus cwj pwm ntawm kev siv tsab ntawv kab ntawm cov keyboard txuag lub sijhawm thaum ntaus ntawv SMS.
Tshuav ob feem pua
Cov keyboard layout dab tsi ua lwm 2% ntawm cov neeg siv? American psychologist thiab tus xibfwb ntawm University of Washington Lub Yim Hli Dvorak, raws li cov qauv qub, tau tsim nws txoj haujlwm yooj yim ntawm cov ntawv. Tab sis nws cov lus qhia tau luag thuam, thiab tsis ntev tsis nco qab tag nrho. Tseem nws txoj haujlwm ntawm kev ua haujlwm ergonomics, kev tshawb fawb, uas yog los ntawm kev ua haujlwm ntawm kev ua haujlwm, cov khoom thiab cov khoom ntawm kev ua haujlwm rau ib tus neeg, tsis tau hnov qab thiab coj mus rau hauv tus lej version ntawm lub Windows OS.
Qhov txheej txheem no muaj npe tom qab nws tus tsim "Dvorak layout". Raws li cov ntaub ntawv pov thawj ntawm kev tshawb fawb, nws ua raws tias kev teeb tsa tsis yog niam ntawv, yog qhov yooj yim tshaj plaws rau cov neeg siv.
