Ingabe uyazi ukuthi yini igundane optical? Ikhompyutha igundane iyithuluzi lokukhomba elibanjwa ngesandla lamakhompyutha, okuhlanganisa into encane enyakaziswa ngaphansi kokulawula ngesandla phakathi kobukhulu obubili endaweni. Ngokwemigomo yekhompyutha, igundane i-peripheral yekhompyutha yomuntu siqu esetshenziselwa ukulawula ukunyakaza kwekhesa kusikrini sekhompyutha. Lokhu okuthunyelwe kubhulogi kubheka umlando wegundane nokubaluleka kwalo emhlabeni wamakhompyutha.
Umlando Wegundane:
Amagundane ekhompyutha aqhamuke kude emashumini ambalwa eminyaka adlule. Igundane lokuqala, invented in 1963 nguDouglas Engelbart, kwakuyinsimbi nensimbi enamasondo amabili nenkinobho. Yayisekelwe kuma-teleprinters okuqala ayesetshenziswa namakhompyutha okuqala. Ukusebenzisa igundane, umsebenzisi wayehambisa elinye lamasondo alibhekise kolunye uhlangothi afuna ukuthi isikhombisi sihambe.
A igundane kwakudingeka ngoba ama-teleprinters anekhibhodi nephrinta kodwa ingenayo indlela yokuhambisa ikhesa esikrinini. Igundane lika-Engelbart lathuthukiswa nguBill English e-Xerox Palo Alto Research Center (I-PARC) ekuqaleni kwawo-1970. Yilapho igundane lathola khona igama. Igundane le-Xerox lalixhunywe kukhompyutha ngentambo. Yayinezinkinobho ezintathu kanye nesondo lokuskrola. Ngaphezu kwalokho, igundane lalingasaxhunywanga kukhompyutha ngentambo — bekungenantambo.
Yini i-Optical Mouse?
I-Optical mouse iyigundane lekhompyutha elisebenzisa ama-LED noma i-laser ukulandelela noma ukubona ukunyakaza. Yethulwe okokuqala ngabakwaMicrosoft ngo-Ephreli 19, 1999. Bekuyigundane lokuqala ukukhiqizwa ngobuningi kusetshenziswa ubuchwepheshe bokulandelela i-Optical. Igundane elibonakalayo liyakwazi ukucaca okukhulu kokunyakaza.
I-Optical mouse iyidivayisi yokufaka ekala ukunyakaza kwayo ngokukhanyisa indawo engaphansi kwayo ngesibani samandla aphansi., bese ulandelela ukukhanya njengoba kukhombisa emuva usebenzisa inzwa ehlanganisiwe. I-Optical mouse iyidivayisi yokufaka ekala ukunyakaza kwayo ngokukhanyisa indawo engaphansi kwayo ngesibani samandla aphansi., bese ulandelela ukukhanya njengoba kukhombisa emuva usebenzisa inzwa ehlanganisiwe.
Igundane elibonakalayo lingasebenza kunoma iyiphi indawo, futhi ayidingi a I-Mouse Pad. I-laser ingaphansi kwegundane futhi isetshenziselwa ukulandelela ukunyakaza. Ifana nebhola legundane kodwa isebenza ngenzwa yokubona. Kunezinguqulo ezimbili zegundane elibonakalayo, leyo esebenzisa ama-LED naleyo esebenzisa i-laser.
Asetshenziswa kakhulu kumakhompuyutha edeskithophu kodwa angatholakala namakhompyutha aphathekayo. Amagundane abonayo avame ukuthandwa ngaphezu kwamagundane ebhola ngoba awadingi indawo ene- I-Mouse Pad noma indawo yegundane, noma umsebenzisi “shanela” igundane emuva naphambili phezu kwephedi noma ngaphezulu.
Amagundane okubona bekuyindinganiso isikhathi eside futhi kuseyiwo akhethwa kakhulu. Asebenza ngokulandelela ukunyakaza kokukhanya phezu kwegundane. Nokho, kukhona ezinye izithiyo ekusebenziseni igundane optical. Kuningi ukugxeka okukhomba ukuzwela kwabo nokunemba okungeyikho. Futhi azihlali isikhathi eside njengozakwabo, igundane eliwumshini.
Amagundane abonakalayo aqalwa njengenye indlela yamagundane ayimishini. Basebenza ngokuchofoza izinkinobho, okuthumela amasignali kanye nedatha kukhompuyutha. Amagundane abonayo anesikhathi eside kakhulu sokuphila kunamagundane ayimishini ngoba awaqukethe izingxenye ezihambayo.
Igundane le-LED
Igundane le-LED lisebenzisa okubomvu (noma blue) i-diode ekhipha ukukhanya (I-LED) ukukhanyisa indawo engaphansi kwayo futhi isebenzisa i-photosensor ukuthola izinguquko kuphethini yokukhanya. Isikhombi segundane kugundane laso le-LED siyabhajwa lapho sibekwe kukhaphethi owugqinsi noma engutsheni futhi kuba nzima ukuhambisa isikhombi segundane ngaleso sikhathi.. Igundane le-LED lihamba phambili ngoba lisebenza kangcono ezindaweni ezithambile.
Amagundane asebenzisa i-LED nenzwa yokukhanya ukuze abone ukunyakaza. I-LED ikhipha umsebe wokukhanya. Njengoba igundane linyakaziswa, ukukhanya okubonisa ngaphandle kuyashintsha. Inzwa yokukhanya ithola ukushuba kokukhanya okuboniswa indawo. Le khasi igundane bese ithumela imininingwane kukhompuyutha. Ikhompyutha icubungula idatha bese iyiguqulela ekunyakazeni kwegundane okukuvumela ukuthi usebenzise igundane ngendlela efanayo naleyo obungenza ngayo ngegundane eliwumshini.. Ngaphezu kokwethembeka nokunembe kakhulu kunamagundane ayimishini, amagundane asebenzisa amandla ebhethri amancane futhi anesikhathi eside sokuphila.
Igundane Laser:
Igundane le-laser iyigundane lekhompyutha elisebenzisa i-laser ukuze libone ukunyakaza okuhlobene nendawo yegundane. I-Optical mouse yokuqala yasungulwa 1996 nguKenjiro Takayanagi enkampanini yaseJapan iLogitech. Igundane le-laser yethulwa ngasekupheleni kwawo-1990, futhi yedlula igundane eliwumshini lohlobo lwakudala ngoba indawo yalo engezansi evalekile ayizange imunce uthuli nokungcola.
Igundane le-laser lisebenzisa i-laser diode ukuze iveze indawo ekhanyayo phezulu. Indawo yokukhanya ihunyushwa ekunyakazeni kwekhesa esikrinini. Igundane le-laser libiza kakhulu kunegundane le-LED futhi lidinga okukhethekile I-Mouse Pad. Igundane le-laser, Ngokolunye uhlangothi, isebenza kahle kakhulu ezindaweni eziqinile ngoba ikhipha umsebe wokukhanya futhi ithola ukunyakaza kwe-beam yokukhanya. Uma igundane kuyigundane laser, kufanele uhlole ukuthi zingaki I-DPI inakho nokuthi iyalungiseka noma cha. Uma uzothenga igundane elisebenziseka kalula, kufanele uthenge engasindi kakhulu noma engasindi kakhulu.
I-Optical Mouse vs Mechanical Mouse
Amagundane asebenzisa ukukhanya kwe-LED kanye ne-photosensor ukuthola ukunyakaza. I-LED ikhanyisa indawo engaphansi kwegundane, futhi i-photosensor ithatha ukukhanya okubonisiwe. Inzwa ibika izinguquko ekukhanyeni kokukhanya kukhompuyutha, ecubungula idatha yokunyakaza futhi iyihumushe ekunyakazeni kwekhesa.
Amagundane omshini asasebenzisa ibhola lerabha. Ibhola lifakwe ku-shaft, futhi izungeza ngaphakathi kwegundane njengoba ulihambisa. Ukujikeleza kwegundane kuthola indawo yebhola ngokubala ama-pulses kagesi akhiqizwa ukunyakaza kwebhola.. Lolu lwazi lube seluthunyelwa kukhompuyutha, lapho ikhesa inyakaziswa khona.
Isiphetho:
Ngethemba ukuthi uyijabulele indatshana yethu mayelana nokuthi iyini igundane elikhanyayo. I-Optical mouse iyithuluzi eliwusizo kakhulu futhi lingasetshenziswa yinoma ubani. Ngalolu lwazi, ungakwazi ukusebenzisa igundane lakho ngokunembe kakhulu, ngokulawula okwengeziwe, futhi ngendlela elula kakhulu esandleni sakho.
Okwamanje, kufanele ube nombono omuhle wokuthi liyini igundane elibonakalayo nokuthi ungalikhetha noma cha esikhundleni esivamile igundane. Uma ungakaqiniseki, ungakwazi njalo ukuzama eyodwa futhi wenze isinqumo ngokusekelwe ekusebenziseni kwakho siqu. Njengoba sithinte kafushane ngenhla, kunezinhlobo eziningi ezahlukene zamagundane optical atholakalayo. Lokhu kungenza inqubo yokuthenga ibe nzima kakhulu. Lokho okushiwo, uma ugcina izinto ezimbalwa engqondweni, kufanele kube lula uma kuqhathaniswa.
Okokuqala nokubalulekile, cabanga ngobukhulu nokuma kwezandla zakho. Izandla ezinkulu, igundane elikhulu. Kukhona namagundane e-ergonomic akheke ngokukhethekile ukuze alingane nosayizi othile wesandla. Ngokwesibonelo, uma unezandla ezincane, ungase uthande ukucabangela igundane elinomumo we-ergonomic oklanyelwe ukulingana nezandla ezincane. Kufanele futhi ucabange ngohlobo lwendawo ozobe usebenzisa igundane kuyo. Uma uzosebenzisa igundane lakho njalo.
