Koetliso ea ho Nepisa Sepheo

Mokhoa oa ho bala lintlha tsa hao

  • Karolelano ea nako bakeng sa sepheo ka seng: nako eohle ea papali e arotsoe ka palo ea lipheo, ka milliseconds (ms). Nako e khutšoanyane e molemo. Ho tobetsa ho fosahetseng ho ja nako, kahoo le hona ho bonahala mona.
  • Ho nepahala: lipheo tse otliloeng li arotsoe ka palo eohle ea ho tobetsa sebakeng sa papali.
  • Ho otla ka potlako ka ho fetisisa: sepheo se le seng seo u se otlileng ka nako e khutšoanyane ka ho fetisisa.
  • Bokhoni ba ho supa: lebelo le bothata li kopantsoe ho ba palo e le ’ngoe, ka li-bit motsotsoaneng (sheba ka tlase). Palo e phahameng e molemo.
  • Kerafo: letheba ka leng ke sepheo se le seng, ’me le bontša nako ea sona ha e bapisoa le bothata ba sona. Mola o nang le likheo ke mola oa hao oa molao oa Fitts.

Molao oa Fitts ke eng?

Molao oa Fitts o re ha sepheo se le hōle le se senyenyane, ho nka nako e telele ho se otla. Ka 1954, Paul Fitts o bontšitse hore nako e eketseha ka mola o otlolohileng ho latela “index of difficulty” ea sepheo, e lekantsoeng ka li-bit [1]. Kajeno hangata e ngoloa e le log2(distance / width + 1) [2]. Baqapi ba o sebelisa ho etsa hore likonopo li be bonolo ho tobetsa.

Lintlha tsa bohlokoa

  • Seo e se lekanyang: lebelo le nepahalo ea ho supa lipheo: ho bona moo sepheo se leng teng, ho isa sesupa moo le ho se emisa holim’a sona.
  • Bokhoni ba ho supa ka toeba: lithuto tsa laboratoring tse sebelisang mokhoa o tloaelehileng li fumana hoo e ka bang 3.7 ho isa ho 4.9 li-bit motsotsoaneng [3].
  • Bokhoni ba ho supa ka monoana: thutong e ’ngoe ea mehala, batho ba 16 ba neng ba tlanya lipheo ba fihletse hoo e ka bang 7 li-bit motsotsoaneng [4]. Lipalo tsa rōna li sebelisa mokhoa o bonolo ho feta (ka tlase), kahoo li ke ke tsa bapisoa ka kotloloho.
  • Lipheo tse nyenyane li-skrineng tsa ho thetsa: hangata monoana o thetsa hoo e ka bang 1 ho isa ho 1.5 mm ho tloha moo motho a neng a rerile; lipheo tse nyenyane ho feta hoo e ka bang 7 mm li fosahetse hangata [5].
  • Ho bapisa toeba le ho thetsa: liphetho li bapisoa feela har’a batho ba sebelisitseng mokhoa o tšoanang oa ho kenya taelo.

Koetliso ea ho nepisa sepheo e sebetsa joang

  1. Tobetsa Qala bohareng ba sebaka sa papali. Oache ea qala.
  2. Otla lipheo. Lipheo tse chitja tse 30 li hlaha ka bonngoe, ka boholo bo meraro, ’me se seng le se seng se hlaha hole le se fetileng. Ho tobetsa ho sa otleng sepheo ho theola ho nepahala ha hao; sepheo se lula se le teng ho fihlela u se otla.
  3. Sheba sephetho sa hao, hammoho le mola oa hao oa molao oa Fitts.

Ha u arolelana lintlha tsa hao, motsoalle oa hao o fumana lipheo tse tšoanang hantle.

Re bala bokhoni ba ho supa ho latela sebaka le boholo ba sepheo ka seng joalokaha ho bontšitsoe, ntle le litokiso tseo mokhoa oa laboratori o li eketsang ho latela moo ho tobetsa ho oelang teng [3]. Ke ka lebaka leo re reng u bapise lipapali tsa hao.

Ke eng e amang ho nepisa sepheo ha hao?

  • Sebaka le boholo. Lipheo tse hōle le tse nyenyane li nka nako e telele ka ho fetisisa: ke sona se boleloang ke molao oa Fitts [1, 2].
  • Sesebelisoa. Toeba, touchpad le monoana li fana ka liphetho tse fapaneng. Lithutong tsa laboratoring, touchpad e ne e lieha haholo ho feta toeba [3].
  • Lebelo kapa tlhokomelo. Ho potlaka ho eketsa liphoso, ’me phoso ka ’ngoe e ja nako. Lintlha tse ntle ka ho fetisisa li fumanoa ka lebelo le tsitsitseng.
  • Lilemo. Thutong e ’ngoe, batho ba baholo ba entse liphoso tse fokolang ho feta bana ba lilemo li 12 ho isa ho 14, ’me ba bile lebelo ho feta batho ba lilemo li 61 ho isa ho 69 [6].
  • Ho ikoetlisa. Linako lia fokotseha lipapaling tse ’maloa tsa pele ha u ntse u tloaela papali.

Seo teko ena e ka se bolelang le seo e ke keng ea se bolela

Koetliso ena ea ho nepisa sepheo e lekanya lebelo le nepahalo ea ho supa ka sesebelisoa sena kajeno. Ha se teko ea bohlale kapa ea bophelo bo botle ba boko ba hao, ’me lintlha tsa nako e khutšoanyane ha li bolele esale pele hore na u ka ba motle hakae lipapaling.

Bapisa le lipapali tsa hao tsa pejana ka sesebelisoa sona seo; toeba e ncha kapa skrine e fapaneng ka boholo li fetola lipalo.

Lipotso tse botsoang khafetsa

Lintlha tse ntle tsa koetliso ea ho nepisa sepheo ke life?

Bapisa le lipapali tsa hao ka sesebelisoa sona seo: papaling e kang ena, lintlha tse ntle ke tse fetang tsa papali ea hao e fetileng. Ha batho ba lekaneng ba se ba bapalitse, sephetho se tla boela se bontše kamoo papali ea hao ea pele e bapisoang le lipapali tsa pele tsa ba bang ba sebelisitseng mokhoa o tšoanang oa ho kenya taelo.

Bokhoni ba ho supa ka li-bit motsotsoaneng ke eng?

Bokhoni ba ho supa bo kopanya bothata ba lipheo le lebelo leo u li otlang ka lona. Bothata bo baloa ka li-bit: log2(distance / width + 1) [2]. Arola ka nako eo ho e nkileng ho otla sepheo ka seng ebe u fumana karolelano, ’me u fumana li-bit motsotsoaneng. Lithuto tsa laboratoring ka toeba li fumana hoo e ka bang 4 ho isa ho 5 li-bit motsotsoaneng ka mokhoa o thata haholoanyane [3].

Na ho loketse ho bapisa toeba le ho thetsa?

Che, ’me ha re li bapise. Monoana le toeba li tsamaea ka litsela tse fapaneng, kahoo sephetho se u bapisa feela le ba bang ba sebelisitseng mokhoa o tšoanang oa ho kenya taelo.

Ke hobane’ng ha lipheo tsa motsoalle oa ka li tšoana le tsa ka?

Sehokelo sa lintlha tse arolelanoeng se na le peo ea papali, kahoo lipheo li hlaha li tšoana. Sena se etsa hore phephetso e be leeme.

Na koetliso ea ho nepisa sepheo ea Helibrain ke mahala?

E. Papali le sephetho sohle sa hao ke mahala: ha ho hlokahale ho ingolisa, imeile kapa tefo.
