Chalkboard tau dominated rau ze li ob centuries. Thaum ntxov xyoo 1990, kev txhawj xeeb txog cov hmoov av chalk thiab kev ua xua ua rau cov tub ntxhais kawm hloov mus rau whiteboard. Tus kws qhia ntawv qhuas cov cuab yeej tshiab, uas tso cai rau lawv nthuav dav thiab nthuav dav hauv ntau yam xim. Tag nrho cov chav kawm tau txais txiaj ntsig los ntawm kev tshem tawm cov chalkboard clutter.

Nrog rau kev siv dav dav ntawm whiteboard, chav kawm tshiab thev naus laus zis pib txuas whiteboard thiab computer. Tam sim no, cov kws qhia ntawv tuaj yeem khaws cov ntsiab lus sau rau ntawm daim kab dam rau hauv lub computer hard disk. Qhov no ua rau lawv luam tawm tam sim ntawd, ua rau lub npe luv luv "whiteboard."Interactive whiteboard (IWB) tau tsim tawm hauv xyoo 1991, uas yuav muaj kev cuam tshuam ntau dua rau kev qhia. Nrog IWB, cov kws qhia ntawv tuaj yeem tso saib tag nrho cov ntsiab lus ntawm lub computer ntawm tag nrho cov chav kawm, yog li tsim kom muaj kev kawm tshiab. Los ntawm kev sib tham sib whiteboard, cov tub ntxhais kawm thiab cov kws qhia ntawv tuaj yeem ua haujlwm ncaj qha rau ntawm qhov screen. Cov kws qhia ntawv tau txais kev txhawb nqa los ntawm cov cuab yeej tshiab zoo siab. Cov tub ntxhais kawm kev koom tes tau nce ntxiv. Kev koom tes hauv chav kawm yog khi kom nce siab. Tus thawj sib tham sib whiteboard system yog ib lub rooj sib tham nrog rau lub projector.

Tsis ntev los no, loj kov screen zaub (tseem hu uaKev sib tham sib tiaj tus vaj huam sib luag (IFPD) ) tau dhau los ua lwm txoj. Cov kev sib tham sib whiteboards no muaj qhov zoo ntawm thawj qhov projector-based IWB system nrog rau cov yam ntxwv ntxiv. Lawv kuj raug nqi tsawg dua lub neej ntawm cov cuab yeej vim yog kev siv hluav taws xob tsawg thiab cov nqi kho mob qis dua.

Niaj hnub no, kev sib tham sib whiteboard tau ruaj khov ua cov cuab yeej qhia. Koj yuav pom lawv nyob rau hauv cov chav kawm hauv tsev kawm ntawv theem pib thiab cov tsev hais plaub hauv tsev kawm ntawv. Cov kws qhia ntawv qhuas lawv lub peev xwm los txhawb kev sib tham thiab tsom ntsoov rau cov tub ntxhais kawm. Cov kws tshawb fawb txog kev kawm kwv yees tias kev siv cov ntawv sib tham sib tham sib yuav txuas ntxiv mus ntxiv. EIBOARD sib tham sib whiteboard tau tsim tawm txij li xyoo 2009 los ua kom tau raws li kev xav tau ntawm kev lag luam no thiab nqa tag nrho cov haujlwm thiab qhov zoo ntawm IWB rau kev kawm ntawv.
