Yiyiphi i-touchpad: mouse, trackball, okanye trackpoint?

Abaphambili bokupasa

Ngaba ufuna ukwazi ukuba yintoni i-touchpad? Eli gama labonakala ngo-1988. Ngaphambi koko, kwakukho ii-device ezibizwa ngokuba yi-trackball kunye ne-trackpoint. Kwaye phambi kwabo isalathisi salawulwa nge mouse.

Isiseko sokuyila i-trackball ibhola, efana ne mouse. Amagundane endala agxininisa embhoshongweni okhethekileyo, ibhola egijime ngaphakathi kwaye, echaphazelekayo, yavelisa umqondiso wokuthi isalathisi sasijikeleza kwisikrini. Kodwa emva kokusebenza iiyure eziliqela nge mouse, uya kuqonda ukuba oku akuyona inketho ekhethekileyo. Ngoko ke, abaqulunqi beza nale fowuni elandelayo yokulawula i-cursor - i-trackball (i-mouse versa). I-trackball iphakanyiswe phezulu okanye kwicala, amaqhosha amabini afumaneka ngaphaya komnye njengomjelo oqhelekileyo. Isundu sihlala etafileni ngokungapheliyo, kwaye kuphela isithupha esitshintsha ibhola ye-trackball. Ibhola ingaba ngowama-1 kuya ku-6 cm ububanzi. Kukho ukwakhiwa kweebhola zokudlala, apho ibhola ilawulwa yinkcazo, emibini okanye eminwe. Kwimizekelo emininzi (ngaphandle kwala maqhosha kunye nebhola), setha ivili lokuhambisa. Inzuzo ebalulekileyo ye-trackball yinto engenakususwa kwesandla kwisandla. Ukuguqula ibhola ngomunwe wakho kunika ukuchaneka ngokuchanekileyo kwesalathisi. Kodwa i-trackball ine-drawback enkulu - evulekile ukusuka phezulu, ihlamba kakhulu ngokukhawuleza. Ukongezelela, i-mechanics i-mechanics, kunye nezixhobo zokucwangcisa izinto zingathembeki kangako kunezo-analogs ze-elektroniki. I-Trackpoint yabonakala emva komdlalo we-trackball. Imelela ezimbini izixhobo ezikhuselekileyo eziguqula ukunyanzeliswa phantsi kwezenzo zamandla asetyenziselwe kubo (iigraji zoxinzelelo). Isalathisi sishukunyiswa ngokuhambelana nomsebenzi osetyenziswayo. I-trackpoint inezinkinobho ezimbini, ezifana neefowuni zemouse. Iintsilelo zeli fowuni yi-drift ye-cursor, kwakunye nesidingo sokunyanzelisa iphaneli, oku kunokukhokelela ekuhambeni kwemisipha yesandla ngexesha lomsebenzi osondeleyo.

Yiyiphi i-touchpad?

Ukuphuhliswa kweendlela zobuchwephesha zokulawula ukuthintela kubangele ukuba kwakunokwenzeka ukudala isixhobo esitsha sokuvelisa i-cursor. Kwabonakala njalo Touchpad. Cinga ukuba yintoni i-touchpad (kwaye Indlela isebenza ngayo). I-touchpad isebenza njengomtshintshi oqhelekileyo: umnxibelelisi uthinta ipasiti (sensitive) yomnxeba ngomnwe, isiphaluka segesi sivale kwaye ishintsho siyabangela. Kamva, umnwe waqala ukuyivala ngaphandle kwesiphaluka sombane, kodwa xa yafakwa kummandla we-sensor pad amandla okutshintsha kwendawo (kunye nokujikeleza kwesekethe kwesebenza). Ngoko ipasti yokuthintela yaba yintsika ye-touchpad. I-Apple ithenge ilayisenisi evela kumvelisi wepati yokuthintela, engaphenduli nje kuphela ukucinezela, kodwa nokuguqula umnwe. Emva koyilo kunye nokuphuhliswa kwezobuchwepheshe (ngo-1994) i-touchpad ibonakala kwiikhomputha eziphathekayo. Enyanisweni, wayebizwa ngokuba yiPopPPad (njengoko i-Apple ibibiza kwaye isenza).

I-touchpad ineenzuzo ezininzi:

- ezibekwe kwiplani ye-laptop, ayifuni indawo eyongezelelweyo;

- ayifuni indawo ebanzi (njenge mouse);

- ukunyaniseka kwekhompyutheni, kunokuba umatshini, isixhobo sikhulu;

- ukukwazi ukufanisa ukchofoza kuyo nayiphi na iqhosha le mouse;

- ukuhamba lula ngomnwe wakho kushukumisela isikhombisi ecaleni kwesikrini;

- ikhuseleke kakuhle kuluthuli nokunyameka.

Iingxaki zi:

Isisombululo esiphantsi kunye (ubunzima ekusebenziseni neenkqubo zemifanekiso);

- ayisebenzi xa usebenzisa ipensela okanye ipeni;

- ayifumanga nommandla omncinci wokuthinta;

- zonke iinyanga ezimbalwa zidinga ukucoca i-pad sensor.

I-Touchpad kwii-laptops

I-touchpad kwiincwadi zeencwadana isetyenzisiwe kakhulu, kuba yenzelwe yona ngokukhethekileyo. I-Touchpad kwii-laptops kwiminyaka yamuva nje inganikezeli ngokukhawuleza kunye nokuphindwe kabini kwimizuzu, kodwa kunye nokuhamba ngokukhenketha nokuhamba. Abanye baze baqaphele umnqweno weminwe emininzi, kunye nemitshukumo: ukujikeleza umfanekiso okanye ukulinganisa umfanekiso (umbhalo) ngeminwe emibili. Ngokuqhelekileyo kufakwa phantsi kwebhodibhodi (phakathi) kunye neefowuni ezimbini zemouse. Kukhona iindawo zokuthintela ezizimeleyo ezizimeleyo zekhompyutheni, ezixhunywe njengemouse (ucingo ngesikhonkco okanye ngesitrato somsakazo).

Ngoku uyazi ukuba yintoni i-touchpad.
