Kev siv cov ntaub ntawv kho mob zoo tshaj plaws yog qhov tseeb duab kho qhov muag technology, tau txais cov txiaj ntsig ntawm infrared electronic whiteboard, thaum kho cov kev tsis txaus siab, tsis yog los ntawm kev tshuaj ntsuam ua ntej muaj zog teeb, cuam tshuam, sau ntawv, yuav ua tau raws li niaj hnub kev sau ntawv cwj pwm, tsim kev ncua, siv rau hauv cov tsev kawm ntawv, kev kawm, kev sib tham.
Optical whiteboard yog ib qho kev kawm zoo lossis kev pabcuam hauv Man-machine nrog kev sib tham, nws tuaj yeem koom tes nrog projectors, khoos phis tawj thiab lwm yam cuab yeej kom ua tiav kev sau ntawv, sau ntawv, kev sib txuas lus sib txuas lus thiab lwm yam haujlwm.
Yeej tsis yooj yim
Qhov tseem ceeb tshaj plaws thiab kev sib nkag siab tsis yooj yim ntawm ib qho hluav taws xob dawb yog:
1 Lub computer interface: International standard Universal USB interface.
2 Resolution: Resolution hais txog cov points (lossis pixels) rau txhua kab. Feem ntau, tus taw tes yog hais txog cov kab rov tav thiab ntsug ntawm ib qho screen lossis saib, thiab ntau dua qhov kev daws teeb meem, qhov tseeb thiab smoother qhov screen.
3 Calibration: General calibration points tsawg kawg 2 points saum toj no, yog li qhov tseeb muab tso rau, yuav tsis tsim kev hloov, ceev ceev.
4 Teb Cov Lus Ceev: Qhov ceev ceev qhov lus teb, qhov ntau ze ntawm kev khiav lag luam ntawm tib neeg, kev siv yooj yim thiab ceev;
5 Kaw cov lus tseeb: High precision, qhov ntau tshaj qhov hnov lus teb.
