Cov thev naus laus zis tshiab tau pib tawm tsam ntawm thaj chaw zoo li kev saib xyuas zoo li kev kawm. Ntau ntxiv, nyob rau hauv ntau lub tsev kawm ntawv koj tuaj yeem pom cov cuab yeej siv uas yog lub hauv paus ntawm cov thev naus laus zis tshiab. Ib qho kev hloov tshiab no yog kev sib tham sib whiteboard. Nws yog ib tug complex, uas muaj ib tug loj kov vaj huam sib luag, ib tug projector thiab lub computer. Lub vijtsam - kov vaj huam sib luag - qhia cov ntaub ntawv los ntawm lub computer desktop siv lub projector.
Raws li txoj kev tso lub projector, qhov sib txawv yog ua los ntawm kev teeb tsa pem hauv ntej thiab nram qab. Qhov yooj yim tshaj plaws yog ncaj, tab sis lawv muaj ntau qhov tsis zoo: thaum siv lawv, koj yuav tsum sawv ntsug rau sab ntawm lub vijtsam, xaiv txoj haujlwm kom tsis txhob thaiv lub teeb flux ntawm lub projector. Lub rear projection sib tham sib whiteboard tsis muaj xws li drawbacks, thiab lub teeb los ntawm lub projector tsis cuam tshuam nrog tus kws qhia (xib fwb), tab sis qhov tsis zoo ntawm xws li ib tug system yog nws tus nqi siab.
Hnub no muaj cov qauv nyob ruaj ruaj lossis txawb ntawm cov khoom siv no, tab sis lawv qhov hnyav tsis tuaj yeem hu ua me me (kwv yees li 200 kilograms, nrog qhov hnyavib lub rooj tsav xwm hauv cheeb tsam ntawm 40 kg).
Raws li txoj kev txiav txim siab txoj haujlwm ntawm tus cim, kev sib tham sib whiteboard tuaj yeem yog:
- infrared;
- ultrasonic;
- kho qhov muag;
- kov resistive;
- electromagnetic.
Ultrasonic thiab infrared thev naus laus zis tsuas yog ua haujlwm nrog qee tus cim, uas, thaum sib cuag nrog lub rooj tsavxwm, tawm cov teeb liab (ultrasonic lossis infrared), uas tau txiav txim los ntawm cov khoom ntsuas ntawm lub rooj tsavxwm. Raws li cov cim qhia no, qhov chaw ntawm tus cim yog xam.
Txoj kev kuaj pom qhov muag tso cai rau koj ua haujlwm nrog txhua yam khoom: infrared sensors "pom" dab tsi yog coj los ze rau ntawm lub rooj tsavxwm, txiav txim siab cov kev tswj xyuas uas xa mus rau lub computer.
Resistive touch thev naus laus zis kuj tso cai rau koj ua haujlwm nrog txhua yam khoom. Cov ntxaij vab tshaus ntawm hom no muaj ob txheej, ntawm qhov uas muaj cov sensors tshwj xeeb. Thaum nias, cov sensors tau tshwm sim thiab txiav txim siab qhov sib koom ua ke ntawm qhov kov.
Electromagnetic technology tsuas yog tso cai rau koj ua haujlwm nrog tus cim tshwj xeeb, txoj haujlwm uas tau txiav txim siab los ntawm qhov chaw sensors.
Txhua yam ntawm cov thev naus laus zis no muaj nws qhov zoo thiab qhov tsis zoo. Txhawm rau xaiv qhov zoo ntawm lub rooj tsavxwm, koj yuav tsum txiav txim siab ntawm nws cov haujlwm tseem ceeb. Yog tias koj xav tau sau rau ntawm lub rooj tsavxwm no tsis yog tsuas yog nyob rau hauv lub xeev tawm, tab sis kuj hloov cov ntaub ntawv tso tawm ntawm qhov screen, ces nws tsim nyog yuav khoom.electromagnetic board muaj ib tug nyuaj txheej. Los ntawm txoj kev, lawv tso cai rau koj los txuas ntau yam kev pab cuam duab thiab cov neeg kho, piv txwv li, PAINT program. Lub luag haujlwm tseem ceeb yog ua los ntawm kev muaj cov lus qhia hauv Lavxias, kev yooj yim ntawm kev ua haujlwm, muaj cov ntsiab lus kho lossis kev pabcuam (tseem ceeb) kev cob qhia hauv koj lub nroog.
Txhua qhov sib tham sib whiteboards tuaj nrog software. Tab sis nws cov ntim tuaj yeem sib txawv heev: qee qhov tsuas muaj cov khoom siv yooj yim xwb, lwm tus yuav muaj cov tsev qiv ntawv, kev cob qhia thiab kev txhim kho, cov ntawv xov xwm, cov lus qhia npaj txhij, thiab lwm yam. Xws li kev sib tham sib whiteboard ntawm lub tsev kawm ntawv lossis lub koom haum yuav dhau los ua tus pabcuam tseem ceeb. Ua hauj lwm nrog kev sib tham sib whiteboard yuav tsum yooj yim thiab yooj yim. Cov ntaub ntawv hais txog tag nrho cov yam ntxwv ntxiv ntawm ntau yam qauv tuaj yeem tau txais ntawm cov vev xaib raug cai ntawm cov tuam txhab.
