Ukuqeqesha ukunemba kokukhomba

Shaya okuqondiwe okungu-30 ngokushesha nangokunemba ngangokunokwenzeka, ubone ukuthi ukukhomba kwakho kuhambisana kanjani nomthetho ka-Fitts. Kumahhala, akukho ukubhalisa.

Indlela yokufunda amaphuzu akho

  • Isikhathi esimaphakathi sokuqondiwe ngakunye: isikhathi sawo wonke umzuliswano sihlukaniswe ngenani lezinto obuziqondile, ngama-millisecond (ms). Esifushane singcono. Ukuchofoza ungashayi kubiza isikhathi, ngakho nakho kuyabonakala lapha.
  • Ukunemba: ukushaya kuhlukaniswe ngakho konke ukuchofoza okwenzile endaweni yokudlala.
  • Ukushaya okushesha kakhulu: isikhathi sakho esisheshayo sokuqondiwe okukodwa.
  • Izinga lokudlulisela: isivinini nobunzima kuhlanganiswe kwaba inombolo eyodwa, ngamabhithi ngomzuzwana (bheka ngezansi). Eliphezulu lingcono.
  • Igrafu: ichashazi ngalinye limele into obuyiqondile, libonisa isikhathi sayo uma siqhathaniswa nobunzima bayo. Umugqa onamadeshi ubonisa umugqa womthetho ka-Fitts wokusebenza kwakho.

Uyini umthetho ka-Fitts?

Umthetho ka-Fitts uthi uma into oqonde ukuyishaya ikude futhi incane, kuthatha isikhathi eside ukuyishaya. Ngo-1954, uPaul Fitts wabonisa ukuthi isikhathi sikhula ngomugqa oqondile ngokuhambisana ‘nenkomba yobunzima’ bento eqondiwe, ekalwa ngamabhithi [1]. Namuhla ngokuvamile ubhalwa kanje: log2(distance / width + 1) [2]. Abaklami bawusebenzisa ukuze benze izinkinobho kube lula ukuzicindezela.

Amaqiniso asheshayo

  • Okukalwayo: ukuthi ukhomba ngokushesha nangokunemba kangakanani ezintweni: ukubona ukuthi into ikuphi, ukuyifinyelela nokuma kuyo.
  • Izinga lokudlulisela ngegundane: izifundo zaselabhorethri ezisebenzisa indlela evamile zithola cishe amabhithi angu-3.7 kuya ku-4.9 ngomzuzwana [3].
  • Izinga lokudlulisela ngomunwe: ocwaningweni olulodwa lwefoni, abantu abangu-16 ababethinta izinto eziqondiwe bafinyelela cishe kumabhithi angu-7 ngomzuzwana [4]. Izinombolo zethu zisebenzisa indlela elula kakhulu (bheka ngezansi), ngakho azinakuqhathaniswa ngokuqondile.
  • Izinto ezincane eziqondiwe ezikrinini zokuthinta: ukuthinta ngomunwe kuvame ukuphambuka cishe ngo-1 kuya ku-1.5 mm; izinto ezingaphansi cishe kuka-7 mm zibangela ukuphuthelwa okuningi [5].
  • Igundane nokuthinta kuqhathaniswa ngokwehlukana: imiphumela iqhathaniswa kuphela phakathi kohlobo olufanayo lwendlela yokufaka.

Indlela okuqeqesha ngayo ukukhomba okusebenza ngayo

  1. Cindezela u-Qala phakathi nendawo yokudlala. Isikhathi siyaqala.
  2. Shaya okuqondiwe. Kuvela izinto eziyindilinga ezingu-30, esisodwa ngesikhathi, ngosayizi abathathu; ngasinye sivela kude nendawo esandulele. Ukuchofoza okuphuthelayo kubalwa njengokunciphisa ukunemba kwakho; into eqondiwe ihlala ikhona uze uyishaye.
  3. Bona umphumela wakho, kanye nomugqa womthetho ka-Fitts.

Uma wabelana ngamaphuzu akho, umngane wakho uthola zona kanye izinto eziqondiwe ozitholile.

Sibala izinga lokudlulisela sisebenzisa ibanga nosayizi wento ngayinye eqondiwe njengoba kubonisiwe, ngaphandle kwezilungiso ezengezwa yindlela evamile yaselabhorethri mayelana nalapho ukuchofoza kugcina khona [3]. Yingakho sithi qhathanisa imizuliswano yakho.

Yini ethinta ukunemba kwakho kokukhomba?

  • Ibanga nosayizi. Izinto ezikude nezincane zithatha isikhathi eside ukuzishaya: yilokho okushiwo umthetho ka-Fitts [1, 2].
  • Idivayisi. Igundane, iphedi yokuthinta nomunwe kunikeza imiphumela ehlukene. Ezifundweni zaselabhorethri, iphedi yokuthinta yayishesha kancane kakhulu kunegundane [3].
  • Isivinini noma ukuqaphela. Ukujaha kwandisa ukuphuthelwa, futhi ukuphuthelwa ngakunye kubiza isikhathi. Amaphuzu amahle kakhulu atholakala ngesivinini esingaguquguquki.
  • Ubudala. Ocwaningweni olulodwa, abantu abadala benza amaphutha ambalwa kunezingane ezineminyaka engu-12 kuya ku-14, futhi bashesha kunabantu abaneminyaka engu-61 kuya ku-69 [6].
  • Ukuzijwayeza. Izikhathi ziyancipha emizuliswaneni embalwa yokuqala njengoba ujwayela umdlalo.

Lokhu kuhlolwa okungakutshela nokungakutsheli

Ukuqeqesha ukukhomba kukala isivinini nokunemba kokukhomba kwakho kule divayisi namuhla. Akukuhloli ukuhlakanipha kwakho noma impilo yobuchopho bakho, futhi amaphuzu esikhathi esifushane awaqageli ukuthi ungaba nekhono elingakanani emidlalweni.

Qhathanisa nemizuliswano yakho yakudala kule divayisi efanayo; igundane elisha noma usayizi wesikrini ohlukile kushintsha izinombolo.

Imibuzo evame ukubuzwa

Yimaphi amaphuzu amahle okuqeqesha ukukhomba?

Qhathanisa nemizuliswano yakho kule divayisi efanayo: emdlalweni ofana nalo, amaphuzu amahle yilawo adlula awomzuliswano wakho odlule. Uma abantu sebewudlale ngokwanele, umphumela uzobonisa nokuthi umzuliswano wakho wokuqala uqhathaniseka kanjani nemizuliswano yokuqala yabanye abadlali abasebenzise indlela efanayo yokufaka.

Liyini izinga lokudlulisela ngamabhithi ngomzuzwana?

Izinga lokudlulisela lihlanganisa ubunzima bezinto obuziqondile nesivinini obuzishaye ngaso. Ubunzima bubalwa ngamabhithi: log2(distance / width + 1) [2]. Hlukanisa ngobude besikhathi esithathwe ukushaya ngakunye, bese uthola isilinganiso; lokho kukunika amabhithi ngomzuzwana. Izifundo zaselabhorethri zegundane zithola cishe amabhithi angu-4 kuya ku-5 ngomzuzwana zisebenzisa indlela eqinile kakhulu [3].

Ingabe kulungile ukuqhathanisa igundane nokuthinta?

Cha, futhi asikuqhathanisi. Umunwe negundane kuhamba ngezindlela ezingafani, ngakho umphumela ukuqhathanisa kuphela nabanye abasebenzise indlela efanayo yokufaka.

Kungani umngane wami ethola izinto eziqondiwe ezifana nezami?

Isixhumanisi samaphuzu okwabelwana ngawo siphethe imbewu yomzuliswano, ngakho izinto eziqondiwe ziyafana. Lokho kwenza inselele ilunge.

Ingabe ukuqeqesha ukukhomba kwe-Helibrain kumahhala?

Yebo. Umdlalo nomphumela wakho ophelele kumahhala: akukho ukubhalisa, i-imeyili noma ukukhokha.

Ukuhlolwa okuhlobene

Bona konke ukuhlolwa kobuchopho kwamahhala okungu-43

Ufuna ukusebenza kulokhu nsuku zonke? Uhlelo lokusebenza lwe-Helibrain (okwamanje lutholakala ngesiNgisi) lunohlelo lwamahhala kanye nezinhlelo ezikhokhelwayo.
