Umdlalo wokuziqhelanisa nokujolisa

Betha iithagethi 30 ngokukhawuleza nangokuchanekileyo kangangoko, uze ubone ukuba indlela ojolisa ngayo ihambelana njani noMthetho kaFitts. Kusimahla, akukho kubhalisa.

Ibhalwe liqela leHelibrainIhlolwe nguRobert(IsiNgesi), umfundi ofundela isidanga sePhD kwi-biophysicsIpapashwe ngomhla we-Ihlolwe okokugqibela ngomhla we-

Indlela yokufunda amanqaku akho

  • Ixesha eliphakathi ngethagethi: ixesha lomdlalo wonke lahlulwe ngenani leethagethi, ngeemillisecond (ms). Ixesha elifutshane lingcono. Ukucofa okuphoseyo kudla ixesha, ngoko nako kuyabonakala apha.
  • Ukuchaneka: inani leethagethi ozibethileyo lahlulwe ngenani lazo zonke izinto ozicofileyo kwindawo yokudlala.
  • Ukubetha okukhawulezayo: elona thagethi ulifikelele ngokukhawuleza.
  • Isantya somsebenzi (throughput): isantya nobunzima obudityaniswe baba linani elinye, ngeebit ngesekhondi (jonga ngezantsi). Okuphezulu kungcono.
  • Itshathi: ichaphaza ngalinye limele ithagethi enye, libonisa ixesha olithathileyo ngokobunzima bayo. Umgca onamachaphaza ubonisa umgca woMthetho kaFitts wakho.

Yintoni uMthetho kaFitts?

UMthetho kaFitts uthi okukhona ithagethi ikude kwaye incinane, kokukhona kuthatha ixesha elide ukuyibetha. Ngo-1954 uPaul Fitts wabonisa ukuba ixesha linyuka ngomlinganiselo othe ngqo ngokwe-"index of difficulty" yethagethi, elinganiswa ngeebit [1]. Namhlanje idla ngokubhalwa njenge-log2(distance / width + 1) [2]. Abayili bayawusebenzisa ukwenza amaqhosha kube lula ukuwabetha.

Iinkcukacha ezikhawulezayo

  • Into elinganiswayo: isantya nokuchaneka kokukhomba iithagethi: ukubona indawo yethagethi, ukuhambisa isalathisi ukuya kuyo nokuma kuyo.
  • Isantya somsebenzi ngemawusi: izifundo zaselabhoratri ezisebenzisa indlela esemgangathweni zifumana malunga ne-3.7 ukuya kwi-4.9 bit ngesekhondi [3].
  • Isantya somsebenzi ngomnwe: kolunye uphando lweefowuni, abantu abayi-16 abacofa iithagethi bafikelela malunga ne-7 bit ngesekhondi [4]. Amanani ethu asebenzisa indlela elula ngakumbi (jonga ngezantsi), ngoko akanakuthelekiswa ngokuthe ngqo.
  • Iithagethi ezincinane kwizikrini eziphathwayo: umnwe udla ngokubeka uchuku malunga ne-1 ukuya kwi-1.5 mm ecaleni kwendawo ekujoliswe kuyo; iithagethi ezincinane kune-7 mm zidla ngokuphoswa [5].
  • Imawusi nokuchukumisa ngokwahlukeneyo: iziphumo zithelekiswa kuphela phakathi kwabantu abasebenzisa uhlobo olunye lolawulo.

Indlela osebenza ngayo umdlalo wokuziqhelanisa nokujolisa

  1. Cofa uQalisa embindini wendawo yokudlala. Iwotshi iya kuqalisa.
  2. Betha iithagethi. Kuvela iithagethi ezingqukuva eziyi-30, ibe nye ngexesha, ngobukhulu obuthathu, kwaye nganye ikude kakhulu kule ibingaphambi kwayo. Ukucofa okuphosayo kunciphisa ukuchaneka kwakho; ithagethi ihlala ikhona de uyibethe.
  3. Jonga iziphumo zakho, kunye nomgca woMthetho kaFitts wakho.

Ukuba wabelana ngamanqaku akho, umhlobo wakho uya kufumana kanye kwa ezo thagethi.

Sibala isantya somsebenzi ngokusebenzisa umgama nobukhulu bethagethi nganye njengoko kubonisiwe, ngaphandle kwezilungiso ezongezwa ngumgangatho waselabhoratri ngokweendawo ezithe zacofwa [3]. Yiyo loo nto sicebisa ukuba uthelekise imidlalo yakho kuphela.

Yintoni echaphazela indlela ojolisa ngayo?

  • Umgama nobukhulu. Iithagethi ezikude nezincinane zithatha ixesha elide: ngumgaqo kaFitts lowo [1, 2].
  • Isixhobo. Imawusi, iphedi yokulawula isalathisi nomnwe zinika iziphumo ezahlukeneyo. Kwizifundo zaselabhoratri, iphedi yokulawula isalathisi yayicotha kakhulu kunemawusi [3].
  • Isantya okanye ukulumka. Ukungxama kwandisa iimpazamo, kwaye impazamo nganye ithatha ixesha. Amanqaku angcono afumaneka ngokuhamba ngesantya esizinzileyo.
  • Ubudala. Kolunye uphando, abantu abadala benza iimpazamo ezimbalwa kunabantwana abaneminyaka eyi-12 ukuya kwi-14, kwaye babekhawuleza kunabantu abaneminyaka eyi-61 ukuya kwi-69 [6].
  • Ukuziqhelanisa. Amaxesha ayancipha kwimidlalo yokuqala embalwa njengoko uqhela umdlalo.

Into onokuyifunda kolu vavanyo nongenakuyifunda

Umdlalo wokuziqhelanisa nokujolisa ulinganisa isantya nokuchaneka kokukhomba ngesi sixhobo namhlanje. Olu asilovavanyo lobukrelekrele okanye lwempilo yengqondo yakho, kwaye amanqaku omdlalo omfutshane awaxeli kwangaphambili ukuba ungadlala kakuhle kangakanani imidlalo.

Thelekisa neziphumo zakho zangaphambili usebenzisa kwa esi sixhobo; imawusi entsha okanye ubungakanani obahlukileyo besikrini buyawatshintsha amanani.

Imibuzo edla ngokubuzwa

Ngawaphi amanqaku alungileyo kumdlalo wokuziqhelanisa nokujolisa?

Thelekisa neziphumo zakho zangaphambili usebenzisa kwa esi sixhobo: kumdlalo ofana nalo, amanqaku alungileyo ngawodlula awakho angaphambili. Xa sele abantu abaneleyo bewudlalile, iziphumo zikwabonisa indlela umdlalo wakho wokuqala othelekiseka ngayo nemidlalo yokuqala yabanye abadlali abasebenzise indlela efanayo yokulawula.

Yintoni isantya somsebenzi ngeebit ngesekhondi?

Isantya somsebenzi sidibanisa ubunzima beethagethi nesantya ozibethe ngaso. Ubunzima bubalwa ngeebit: log2(distance / width + 1) [2]. Bahlule ubunzima ngexesha elithathwe kukubetha ngakunye, uze ubale umndilili; ufumana inani leebit ngesekhondi. Izifundo zaselabhoratri ngemawusi zifumana malunga ne-4 ukuya kwi-5 bit ngesekhondi xa kusetyenziswa indlela engqongqo ngakumbi [3].

Ngaba kufanelekile ukuthelekisa imawusi nokuchukumisa?

Hayi, kwaye asikwenzi oko. Umnwe nemawusi zihamba ngeendlela ezahlukeneyo, ngoko iziphumo zikuthelekisa kuphela nabanye abasebenzise indlela efanayo yokulawula.

Kutheni iithagethi zomhlobo wam zifana nezam?

Ikhonkco lamanqaku ekwabelwana ngalo liquka imbewu yomdlalo, ngoko kuvela kwa ezo thagethi. Oku kwenza umngeni ube nobulungisa.

Ngaba umdlalo wokuziqhelanisa nokujolisa weHelibrain usimahla?

Ewe. Umdlalo nazo zonke iziphumo zakho kusimahla: akukho kubhalisa, akukho dilesi ye-imeyile, akukho ntlawulo.
