Njani i mouse computer

Enye yeendima ezibalulekileyo nayiphi na inkqubo yekhompyutha mihla - mouse computer. Oku "besikrekrethi" kudala yinxalenye nje kuphela desktops kodwa laptop, nangona kwifomu modified.

Kubonakala ngathi mouse computer, wonke umntu uyazi. Ngandlel 'ithile, ngokwenene ikhangeleka ingumfo olizothe ezaziwayo-kakuhle, nakuba sikho bamathidala. Kukholelwa ukuba izizukulwana elizayo abasebenzisa lo lombutho boni. Nangona, xa kuphela ngenxa yokuba ikhompyutha mouse mihla ngakumbi eyenziwa engenazingcingo, ndayihluthwa "Yibambe ngomsila".

Umgaqo esebenza ngayo le divayisi elula Akumangalisi kakhulu: xa isusiwe phezu komhlaba uququzelelo ke idluliselwe kwi computer, apho isoftware ezizodwa iguqulelwa kwi intshukumo salathisi kwi isalathisi screen. Yintoni umdla kukuba, oko kungenzeka kuphela ukuba utolo eliqhelekileyo yokusebenza, kodwa umlinganiswa kumdlalo computer. Unobangela lula okubonakala Uyayifihla umsebenzi iinjineli, iinjineli elektroniki kunye badwelisi benkqubo. Kuxhomekeka iimpawu noshowo le mouse computer ukuze abe intshukumo irejista ezahlukeneyo. Masikhumbule ukuba yintoni umahluko phakathi kwezi zixhobo ebonakala ncam.

Umfuziselo yokuqala ukuvela kwiminyaka engama-50 eyadlulayo, kwakukho mechanical. Ngaphakathi idivaysi ibhola metal omkhulu isale ngomaleko irabha. Icala elisezantsi, weza wadibana kumphezulu engaphandle, yaye ezinye ezimbini - kunye roller. Ukuba kusenokuba ezine, kodwa eziye zajongwa ezimbini kuphela. Xa uhambisa isandla ebambe ibhola mouse r rolls ndisandula ukudlula kancinane kubo - iswitshi, uze emva koko similise kulandelelwano imiqondiso yombane ukuba zithunyelwa kwikhompyutha. nosaziwayo ezimbini kwanele sokufumana yokuququzelela indawo kwi-moya. Ububi le isisombululo zibandakanya imfuno ibhola periodic zokucoca, ukuba ndingahlangani ukungcola (iinwele umoya ndingahlangani uthuli) kunye nokutshintshwa kweekhomponenti kunxitywe.

Kungekudala kwafakwa izisombululo woqondo-mechanical. Ngokwangaphandle, yonke into kuhlala ingatshintshanga, kodwa iiswitshi ziye zapheliswa, indawo isisombululo irobust ezongeziweyo - optocoupler. Kuba "eyoyikekayo 'igama ngokufihla zeLED kakhulu ayinabungozi kunye sensor enombala, ngokuhlangeneyo wabhekisela sibini nje opto. mqengqeleki nganye ladityaniswa kunye ivili tubing amalungiselelo phakathi woluvo kunye diode. Xa kokutshintsha umsinga umqadi uphazamiseko ukuba yabhalwa ngu menzi woluvo kwaye idluliselwe kwi-computer. Ukwazi amaza shift "window / udonga", oko kwenzeka ukumisela isantya kwaye ngakwicala intshukumo.

Ngo-1999, bekukho ikhompyutha mouse yokuqala, ekuthiwa enombala, apho indlela ngomatshini yokurekhoda intshukumo likwazile ukunika ngokupheleleyo. LED kusibonisa komhlaba phantsi mouse, kwaye ikhamera abangekaphuhli abanye rhoqo kwenza imifanekiso. Iyunithi iprosesa ephatha kuzo ngokusekelwe iziphumo iqukumbela ukuba uqina kunye nezikhokelo ukubana. Sinako ukudlulisela kuphela inkqubo umqhubi data.

Kungekudala kwafakwa laser ukulungiswa. Iprosesa ibe nemveliso ngakumbi, ugxininisa ukuchaneka liye landa, imiphezulu "yingxaki" apho woluvo alusebenzi nje, beziphantse ukumka. Umehluko omkhulu kwezinye uhlobo woqondo LED, leyo likhupha ingabonakali, infrared. Hi ndlela leyi, ikhompyutha mouse kakhulu ebiza - yinto laser. Noko ke, ixabiso layo eliphezulu (ngaphezu kwama-24 amawaka eerandi) kungenxa amatshe ikakhulu okuhombisa, hayi iinkalo zezobugcisa.
