Nrog rau kev txhim kho txuas ntxiv ntawm thev naus laus zis, chav sib tham yuav tsum tsis yog tsuas yog ua haujlwm ntawm kev tuav cov rooj sib tham, tab sis kuj muaj qhov zoo ntawm cov duab thiab suab zoo kom tau raws li cov kev xav tau ntawm ntau lub rooj sib tham, xws li kev nthuav qhia thiab kev sib pauv kev kawm.
Cov khoom siv hauv chav sib tham niaj hnub feem ntau siv cov projectors. Txawm li cas los xij, vim muaj ntau yam kev txwv, xws li qhov tsis pom tseeb thiab qhov loj me me, qhov projectors tsis tuaj yeem ua tau raws li qhov xav tau ntawm ntau lub rooj sib tham niaj hnub no. Disadvantages ntawm tsoos projection khoom:

2. Qhov loj ntawm cov cuab yeej projection feem ntau yog tsau, ua rau nws nyuaj kom haum rau qhov ntev ntawm cov chav sib tham loj.
3. Qhov projection muaj kev cuam tshuam zoo heev los ntawm lub teeb pom kev zoo, yuav tsum tau kaw cov ntaub thaiv thaum siv.
Txhawm rau hloov kho cov kev xav tau ntawm lub neej niaj hnub thiab kev sib tham ua lag luam, cov khoom siv yuav tsum tau hloov kho dua tshiab, siv cov khoom siv LED tshiab uas tuaj yeem hloov kho raws li qhov loj me, muab qhov pom tseeb siab dua, ci ntsa iab dua, tus nqi qis dua, thiab kev siv thev naus laus zis ntau dua.

3. Cov lus qhia LED tsis cuam tshuam los ntawm lub teeb pom kev zoo, yog li tsis tas yuav tsum kaw cov ntaub thaiv hauv chav sib tham. Txhua LED teeb hlaws muaj lub neej ntev txog li 100,000 teev, ua rau lub neej ntev heev rau cov lus qhia LED.
4. Thaum siv cov lus qhia LED, cov ntsiab lus ntawm lub vijtsam yuav tsis pom los ntawm tib neeg, ua kom muaj kev ncaj ncees ntawm cov ntsiab lus pom.
