Ukukhetha okunzima: laser mouse noma optical?

Kubonakala sengathi i- computer yegundane ayiyona ingxenye ebaluleke kakhulu kukhompyutha yonke, kodwa cha, ngaphandle kwayo, ukusebenza i-PC kuba yinkimbinkimbi kakhulu, hhayi yinto ejabulisayo. I-brand A4Tech, i-Logitech, i-Defender ilokhu ilwa nomunye ngokudala i- computer engcono kakhulu yegundane emhlabeni. Yingakho okwamanje izihlobo ezahlukene zezinkampani zekhompyutha ziqhubeka zishintsha ngcono. Uma uhlale uqapha zonke izakhi zomsindo emakethe yamakhompiyutha, futhi ngesikhathi esifanayo uthenge, okungenani enye yamamodeli wakamuva, ungakwazi ukumane uhlale ngaphandle kwemali.

Ngokuqinisekile, abaningi benu bakhumbula amagundane okuqala awazi ukunyakaza nokuxhumanisa ngenxa ye-bulb yerabha ngaphakathi. Yonke into endala ihlala ingena esikhundleni esisha, ngakho-ke namuhla kuningi okukhunjulwa ngaso sonke isikhathi mayelana nabasebenzi bezinsimbi. I-mouse ebonakalayo yeza ukubuyisela imishini, ihlanganise zonke izimfanelo zayo ezinhle kakhulu. Kodwa-ke, sekudlule iminyaka embalwa, futhi i-laser mouse, ukuthuthukiswa kwakamuva kwezinkampani ezahlukene ezikhiqiza amadivaysi okufakwayo, sekuvele kakade emnyango.

Okukhethwa kukho okuyinhloko: igundane laser noma optical?

Ngesikhathi abafana abavela ku-A4Tech bengakabi nesimiso esisha esihle sokubona izixhumanisi negundane, wonke umsebenzisi wekhompyutha, i-laptop noma i-netbook unokuzikhethela: i-laser mouse noma i-optical eyodwa. Yingakho kudingekile ukuqonda izinzuzo kanye nokulimala kwegundane laser kanye ne-optical, ukuze kungabi khona nobunzima ekusebenziseni enye yezinketho ezinikeziwe.

Ngokungangabazeki, igundane lekhompiyutha, ngaphezu kokushayela isikhombisi esikrinini, inezici ezimbili ezibalulekile - ukunemba nokusheshisa. Lawa mazwi azoqinisekiswa nanoma yimuphi umdlali wezemidlalo. Emncintiswaneni wokunemba kwe-manipulator ye mechanical ayikho ithuba lokubhekana namadivayisi amasha wokufaka. Ngakho-ke, kungakhathaliseki ukuthi igundane laser noma optical, basuke kakhulu baye emncintiswaneni wokunemba kusuka mouse mouse.

Isimiso sokusebenza kokubili izinhlobo zamagundane kuyafana: inzwa isusa isithombe sobuso, futhi i-chip ngaphakathi kwegundane ihlaziya lesi sithombe futhi inquma izixhumanisi. Uma i-optical, kanye ne-laser mouse, isebenza, indawo evela ngaphansi kwe-manipulator igcizelelwe. Lokhu kwenziwa ngesithombe esingcono futhi esinembile, esizokwenza isici esikhethekile sokufunda, esisemgodini ovulekile umsebenzi we-LED, ngenkathi kulayisi ngokuqondile i-laser. Ngendlela, i-laser ikhanyisa kangcono indawo efundwayo, okusho ukuthi izinga lomfanekiso wesithombe licacile kakhulu kunelo-LED. Imouse ye-laser iqondile kakhulu kune-optical eyodwa, ngoba i-laser inembile kaningi kune-LED futhi ayikuhlanekisayo umfanekiso ofundwayo. Lona okuthiwa umehluko omncane phakathi kwegundane laser kanye negundane optical.

Kodwa-ke, ngaphezu kokunemba kumuntu ophethe kahle, isinqumo nesivinini kubaluleke kakhulu. Isixazululo silinganiswa ngamayunithi abizwa ngokuthi i-dpi (ngesiRussia - kumachashazi ngamasentimitha). Futhi, i-mouse laser inezinqumo ezifinyelela ezinkulungwaneni ezimbili, kuyilapho igundane le-optical lingase liziqhayise ngamakhulu ayishumi nambili amaphuzu amaphuzu ngamasentimitha amabili. Eqinisweni, isandiso esifanele kunazo zonke futhi esilungele ukuphathwa kwamagundane amahle ngamachashazi angamakhulu ayisishiyagalombili ngamasentimitha, kodwa abakhiqizi bekhompyutha be-computer manipulators basebenzisa lezi zikhombisi njengendlela yokuhambisa amancane. Uma ufuna, isinqumo segundane singashintshwa kuphaneli yokulawula, bese uzizwa uqobo zonke izinzuzo nezindleko zesinqumo esiphezulu se-manipulator.

Amagundane asebenzayo ayatholakala kuma- interfaces amabili e-PS / 2 ne- USB, kuyilapho ama-laser ahlomele kuphela isikhombimsebenzisi se-USB. Ubuchwepheshe be-USB buyinkimbinkimbi kakhulu, futhi isivinini sokudlulisa idatha singaba ngaphansi kwe-PS / 2. Ngakho-ke, isikhombisi sizohamba ngokuzungezile isikrini hhayi ngokushelela.

Manje njengoba usujwayelene kakhulu namadivayisi wokufaka, zama ukuthola ukuthi i-laser mouse noma i-optical iyona engcono kuwe, futhi qiniseka ukuthi uzama kokubili.
