Thapiso ya go Tlhomamisa go Leba

Itaya diponagano tse 30 ka bonako le ka nepiso ka mo o ka kgonang, mme o bone gore go leba ga gago go latela molao wa Fitts jang. Mahala, ga go tlhokege go ikwadisa.

Go tlhaloganya dintlha tsa gago

  • Palogare ya nako ka ponagano: nako yotlhe ya motshameko e kgaogantswe ka palo ya diponagano, ka dimilisekonto (ms). Nako e khutshwane e botoka. Go tobetsa o sa iteye go ja nako, ka jalo go bonala le fano.
  • Nepiso: palo ya tse o di iteilweng e kgaogantswe ka palo yotlhe ya ditobetso mo lefelong la motshameko.
  • Go itaya ka bonako thata: ponagano e le nngwe e o e iteileng ka bonako go gaisa tsotlhe.
  • Bokgoni jwa go supa: lebelo le bothata di kopantswe go nna palo e le nngwe, ka dibiti ka motsotswana (bona fa tlase). E e kwa godimo e botoka.
  • Kerafô: khutlo nngwe le nngwe e emela ponagano e le nngwe, e bontsha nako ya yone le gore e ne e le thata go le kana kang. Mola o o thaletsweng o bontsha mola wa gago wa molao wa Fitts.

Molao wa Fitts ke eng?

Molao wa Fitts o tlhalosa gore fa ponagano e le kgakala e bile e le nnye, go tsaya nako e telele go e itaya. Ka 1954, Paul Fitts o ne a bontsha gore nako e oketsega ka tsela e e tlhamaletseng fa go oketsega "index of difficulty" ya ponagano, e e lekanngwang ka dibiti [1]. Gompieno gantsi e kwalwa jaana: log2(distance / width + 1) [2]. Bathamapontle ba o dirisa go dira gore dibutana di nne motlhofo go di itaya.

Dintlha ka bonako

  • Se e se lekanyang: lebelo le nepiso fa o supa diponagano: go bona kwa ponagano e leng teng, go isa sesupo koo le go se emisa mo go yone.
  • Bokgoni jwa go supa ka toeba: dipatlisiso tsa laboratoring tse di dirisang mokgwa wa maemo di fitlhela dipoelo tsa 3.7 go ya go 4.9 bits ka motsotswana [3].
  • Bokgoni jwa go supa ka monwana: mo patlisisong e nngwe ya mogala, batho ba le 16 ba ba neng ba kgoma diponagano ba fitlheletse mo e ka nnang 7 bits ka motsotswana [4]. Dipalo tsa rona di dirisa mokgwa o o motlhofo (fa tlase), ka jalo ga di tshwane ka tlhamalalo.
  • Diponagano tse dinnye mo disekrineng tse di kgomang: monwana o ama mo e ka nnang 1 go ya go 1.5 mm go fosa kwa o neng o ikaeletse teng; diponagano tse di ka fa tlase ga mo e ka nnang 7 mm di dira gore o fose gantsi [5].
  • Go farologanya toeba le go kgoma: dipoelo di bapisiwa fela fa go dirisitswe mofuta o o tshwanang wa sedirisiwa sa go laola.

Thapiso ya go leba e dira jang

  1. Tobetsa Simolola fa gare ga lefelo la motshameko. Tshupanako e a simolola.
  2. Itaya diponagano. Go tla tlhaga diponagano tse 30 tse di kgolokwe ka bongwe ka nako, ka bogolo jo bo farologaneng jo tharo; nngwe le nngwe e nna kgakala sentle le e e fetileng. Go tobetsa o sa iteye go fokotsa nepiso ya gago; ponagano e nna teng go fitlha o e itaya.
  3. Bona dipoelo tsa gago, le mola wa gago wa molao wa Fitts.

Fa o abelana ka dintlha tsa gago, tsala ya gago e bona diponagano tse di tshwanang tota.

Re bala bokgoni jwa go supa ka go dirisa bokgakala le bogolo jwa ponagano nngwe le nngwe jaaka go bontshitswe, re sa dire diphetogo tse mokgwa wa maemo wa laboratoring o di dirang go ya ka kwa ditobetso di welang teng [3]. Ke ka moo re reng o bapise dipoelo le metshameko ya gago ya pele.

Ke eng se se amang go leba ga gago?

  • Bokgakala le bogolo. Diponagano tse dinnye le tse di kgakala di tsaya nako e telele go di itaya: oo ke molao wa Fitts [1, 2].
  • Sedirisiwa. Toeba, sedirisiwa sa go laola ka go kgoma le monwana di naya dipoelo tse di farologaneng. Mo dipatlisisong tsa laboratoring, sedirisiwa sa go laola ka go kgoma se ne se le bonya thata go feta toeba [3].
  • Lebelo kgotsa kelotlhoko. Go itlhaganelela go oketsa diphoso, mme phoso nngwe le nngwe e ja nako. Dintlha tse di kwa godimo di bonwa fa o tswelela ka lebelo le le tlhomameng.
  • Dingwaga. Mo patlisisong nngwe, bagolo ba ne ba dira diphoso di le mmalwa go feta bana ba dingwaga tse 12 go ya go 14, mme ba ne ba le bonako go feta batho ba dingwaga tse 61 go ya go 69 [6].
  • Go ikatisa. Dinako di a fokotsega mo metshamekong ya ntlha fa o ntse o tlwaela motshameko.

Se teko eno e ka go bolelelang le se e ka se go bolelelang

Thapiso ya go leba e lekanya lebelo le nepiso ya go supa ka sedirisiwa seno gompieno. Ga se teko ya botlhale kgotsa ya botsogo jwa boboko jwa gago, mme maduo a motshameko o mokhutshwane ga a bolelele pele gore o tla nna setswerere go le kana kang mo metshamekong.

Bapisa le metshameko ya gago ya pele mo sedirisiweng se se tshwanang; toeba e ntšha kgotsa bogolo jo bo farologaneng jwa sekirini bo fetola dipalo.

Dipotso tse di bodiwang gantsi

Maduo a a siameng a thapiso ya go leba ke afe?

Bapisa le metshameko ya gago mo sedirisiweng se se tshwanang: mo motshamekong o o tshwanang le ono, maduo a a siameng ke a a fetang a gago a bofelo. Fa batho ba le bantsi ba setse ba tshamekile, dipoelo di tla bontsha le gore motshameko wa gago wa ntlha o bapisiwa jang le metshameko ya ntlha ya ba bangwe ba ba dirisitseng sedirisiwa se se tshwanang.

Bokgoni jwa go supa ka dibiti ka motsotswana ke eng?

Bokgoni jwa go supa bo kopanya bothata jwa diponagano le lebelo la go di itaya. Bothata bo balwa ka dibiti: log2(distance / width + 1) [2]. Bo kgaoganye ka nako e go tsereng go itaya ponagano nngwe le nngwe, mme o tseye palogare; o bona dibiti ka motsotswana. Dipatlisiso tsa laboratoring tse di dirisang toeba di fitlhela mo e ka nnang 4 go ya go 5 bits ka motsotswana fa go dirisiwa mokgwa o o gagametseng thata [3].

A go siame go bapisa toeba le go kgoma?

Nnyaa, mme ga re di bapise. Monwana le toeba di tsamaya ka ditsela tse di farologaneng, ka jalo dipoelo di go bapisa fela le ba bangwe ba ba dirisitseng sedirisiwa se se tshwanang.

Ke eng fa diponagano tsa tsala ya me di tshwana le tsa me?

Kgokagano ya go abelana ka maduo e tshola peo ya motshameko, ka jalo diponagano di tlhaga di tshwana. Seo se dira gore kgaisano e siame.

A thapiso ya go leba ya Helibrain ke mahala?

Ee. Motshameko le dipoelo tsotlhe tsa gago ke mahala: ga go tlhokege go ikwadisa, imeile kgotsa go duela.

Diteko tse di amanang

Bona diteko tsotlhe tsa mahala tsa boboko di le 43

A o batla go dira seno letsatsi le letsatsi? App ya Helibrain (e teng ka Seesemane fela ga jaana) e na le leano la mahala le a a duelwang.
