Olani tshitendeledzi tsho linganaho

Olani tshitendeledzi u mona na tshithoma nga tshifhinga tshithihi ni vhone uri tsho lingana lungafhani. Ndi mahala, a hu ṱoḓei u ḓiṅwalisa.

U vhala hani mvelelo yaṋu

  • U lingana: 100% hu bviswa tshikalo tsha uri mutalo waṋu wo bva hani kha tshitendeledzi tsho fanelaho, nga vhunzhi ha tshikalo tsha radius yatsho. Mutalo une wa tshimbila nga u dzinginyala ha 2% nga vhunzhi u wana 98%.
  • Mivhala ya mutalo waṋu: ndi mudala hune mutalo wa vha kha tshitendeledzi, wa fhira kha ṱaḓa, wa swika kha mutsuku hune wa vha kule navho.
  • Tshitendeledzi tsha mitalo ya u siana: ndi tshitendeledzi tsho fanelaho vhukuma kha tshifanyiso tshaṋu. Mutalo waṋu u tshi sendela tsini natsho, mvelelo i ya nṱha.
  • Mvelelo yaṋu ya khwine: ndi mvelelo ya nṱhesa kha hei browser, yo vhulungwaho nga thungo ya u shumisa muthetshe na ya mbeu ya khomphyutha, ngauri munwe na mbeu zwi ola nga nḓila dzo fhambanaho vhukuma.
  • Thungo: u monisa nga thungo ya tshikhathi kana nga thungo yo fhambanaho nayo. Vhathu vhanzhi kha US vha ola vha tshi monisa nga thungo yo fhambanaho na tshikhathi; ngei Japan vhanzhi vha ola vha tshi monisa nga thungo ya tshikhathi [1].

Ni nga ola tshitendeledzi tsho linganaho nga tshanḓa?

A si nga vhukuma, fhedzi ni nga sendela tsini natsho. Tshitendeledzi tsho olwaho nga tshanḓa tshi dzinginyea zwiṱuku tshifhinga tshoṱhe, ngauri tshanḓa tshi a ongolowa na u gidima musi tshi tshi tevhela tshikombama [2]. Kha tshikalo tshashu, mutalo une wa bva kha tshitendeledzi nga 2% nga vhunzhi u wana 98%. Tshitendeledzi tsha maḓivhazwakale tsho ṱanḓavhuwaho tsha mudededzi wa mbalo wa Canada tshi anganyelwa uri tshi lingana nga 99.7% kha u anganyela ha muṅwe muṅwali wa blog [3].

Zwiṱuku zwa u ḓivha

  • Thungo i bva hune wa alutshela hone: kha zwifanyiso zwa US zwi ṱoḓaho 50,000 kha mutambo wa Google wa Quick, Draw!, 86% ya zwitendeledzi zwo olwa nga thungo yo fhambanaho na tshikhathi; kha zwifanyiso zwa Japan zwi ṱoḓaho 800, 80% zwo olwa nga thungo ya tshikhathi [1].
  • Mayo a u ṅwala a a zwi shandula: vhana vha Japan vha ola zwitendeledzi zwinzhi nga thungo ya tshikhathi musi vha tshi ya tshikoloni; vha US vha ita zwinzhi nga thungo yo fhambanaho na tshikhathi. Vhana vha Japan vha dzulaho US vho ola zwiṱuku nga thungo ya tshikhathi [4].
  • Mulayo wa luvhilo lwa tshanḓa: tshanḓa tshi tshimbila nga u ongolowa kha zwikombama zwi tsitsikanaho nahone nga u ṱavhanya kha zwipiḓa zwi si na tshikombama tshinzhi ((mulayo wa maanḓa a zwipiḓa zwivhili kha zwiraru)). Kha tshitendeledzi tshikombama tshi a fana fhethu hoṱhe, ngauralo mulayo uyu u amba uri luvhilo lu fanela u dzula lu tshi eḓana [2][5].
  • Mwali wa ḽifhasi: mudededzi wa mbalo we a vha kha vidio ya tshitendeledzi tsho ḓivheaho nga vhathu vhanzhi o amba nga murahu uri madzina a mwali wa ḽifhasi wa u ola zwitendeledzi nga tshanḓa o vha e u sea hawe vhagudi [6].
  • A si tshiga tsha mutakalo: muhumbulo wa miṅwaha ya 1970 wa uri u ola zwitendeledzi nga thungo ya tshikhathi ndi tshiga tsha u vhavha muhumbuloni a wo ngo tikedzwa nga ṱhoḓisiso dza nga murahu [7].

Ndingo ya tshitendeledzi i shuma hani

  1. Olani. Vheani munwe waṋu (kana puṱedzo ya mbeu ya khomphyutha) fhethu naho hu ngafhi ni ole tshitendeledzi tshithihi u mona na tshithoma, nga u suvha huthihi.
  2. Sedzani musi tshi tshi khou itea. Musi no no mona tshipiḓa tsha tshitendeledzi, u lingana hu bvelela vhukati nahone mutalo wa shandula muvhala.
  3. Vusani munwe. Musi no fhedza, tshitendeledzi tsho fanelaho vhukuma tshi bvelela nga mitalo ya u siana nahone tshifanyiso tshaṋu tshi a lingwa.

U vhalwa, tshifanyiso tshi tea u mona na 320° ya tshitendeledzi, tshifhela tsini na he tsha thoma hone, tshi tea u vha tshihulwane (radius ya 15% ya vhuphara ha fhethu ha u ola) nahone tshi fhedzwe nga fhasi ha sekonde dza 30. Ri humbela u ita lup eto luthihi fhedzi. Ri ola tshitendeledzi tshi fanelaho nga points dzaṋu nga nḓila ya least squares nahone ra kala vhukati ha kule na tsho. Zwitendeledzi zwa munwe zwi vhambedzwa fhedzi na zwiṅwe zwa munwe.

Ndi ngani zwi tshi konḓa u ola tshitendeledzi tsho linganaho?

U ola tshitendeledzi zwi ṱoḓa uri shouludara, lukudavhavha, tshanḓa na minwe zwi shume zwoṱhe, ngeno thungo ya u tshimbila i tshi dzulela u shanduka. Tshanḓa tshaṋu tshi dzhiela nṱha u ṱavhanya na u ongolowa musi tshi tevhela tshikombama [2], nahone tshanduko iṅwe na iṅwe ya luvhilo ndi tshibuli tsha u pambuwa u ya nnda kana nga ngomu. Kha luṱingo, munwe waṋu u dovha wa dzumba mutalo une na khou u ola. Mbeu ya khomphyutha i tshimbisa tshanḓa tshoṱhe, ndi ngazwo zwitendeledzi zwa mbeu na zwa munwe zwi tshi wana mvelelo dzo fhambanaho.

Nyeletshedzo dza u ola tshitendeledzi tsho linganaho

  • Olani tshihulwane ni shumise tshanḓa tshoṱhe. Zwitendeledzi zwiṱuku zwi olwaho nga minwe fhedzi zwi dzinginyea vhukuma.
  • Dzudzanyani luvhilo. Ni songo ongolowa nga maanḓa: u ola nga u ongolowa vhukuma hu anzela u ita uri tshanḓa tshi tetemee.
  • Sedzani tshithoma tsha vhukati, hu si mutalo. Mushumo woṱhe ndi u dzula ni vhukati ha tshithoma nga kule ku fanaho.
  • Fhedzisani lup eto nga u bonya. Zwitendeledzi zwinzhi zwi xelelwa nga phointhi magumoni, hune vhathu vha ṱavhanyedza u swika hune vha thoma hone.

Ndingo iyi i ni vhudza mini, nahone a i ni vhudzi mini

Ndingo ya tshitendeledzi ndi mutsiko wa u langa tshanḓa wa u ḓiphina. Mvelelo yaṋu i bva kha tshishumiswa tshaṋu, saizi ya tshikirini, arali ni tshi shumisa munwe, peni kana mbeu ya khomphyutha, na nḓowenḓowe. A si ndingo ya zwa ngalafho kana ya u kala u tetemela; madokotela vha shumisa miṅwe mishumo ya u ola, i ngaho spirals, kha zwenezwo [8]. Thungo ine na ola ngayo a i ambi tshithu nga ha mutakalo waṋu.

Mbudziso dzine dza anzela u vhudziswa

Zwi a konadzea u ola tshitendeledzi tsho linganaho nga tshanḓa?

A hu na tshitendeledzi tsho olwaho nga tshanḓa tshine tsha lingana nga vhukuma, fhedzi vhathu vha a kona u sendela tsini natsho. Kha ndingo ya tshitendeledzi ya Helibrain, u lingana ndi 100% hu tshi bviswa u dzinginyea ha mutalo nga vhunzhi, ngauralo mutalo une wa bva nga 2% nga vhunzhi u wana 98%. U swika kha 100% nga vhukuma zwi ṱoḓa mutalo une wa sa dzinginyee na luthihi.

Vhathu vhanzhi vha ola zwitendeledzi nga thungo ya tshikhathi kana yo fhambanaho nayo?

Zwi bva hune na alutshela hone. Kha zwifanyiso zwa Google Quick, Draw!, 86% ya zwitendeledzi zwa US zwi ṱoḓaho 50,000 zwo olwa nga thungo yo fhambanaho na tshikhathi, ngeno 80% ya zwitendeledzi zwa Japan zwi ṱoḓaho 800 zwo olwa nga thungo ya tshikhathi [1]. Zwi vhonala uri mikhuvha ya u ṅwala ndi ya ndeme vhukuma u fhira uri ni shumisa tshanḓa tshifhio [4].

Mvelelo yanga ya u lingana i vhalwa hani?

Ndingo ya tshitendeledzi ya Helibrain i wana tshitendeledzi tsho fanelaho kha points dzoṱhe dza mutalo waṋu (u anganyela ha least squares), ya tevhela ya kala uri point iṅwe na iṅwe i kule lungafhani natsho. Kule ha vhukati, musi hu tshi vhambedzwa na radius ya tshitendeledzi, ndi u dzinginyea haṋu; u lingana ndi 100% hu tshi bviswa u dzinginyea. Tshivhumbeo tsha ovhili, tshipingo kana u dzhena ha mitalo kha muṅwe zwiṱukuṱuku zwiṱoṱhe zwi fhungudza mvelelo.

Ndi ngani mvelelo yanga i tshi fhambana kha luṱingo na kha khomphyutha yanga?

Munwe na mbeu ya khomphyutha zwi shumisa misipha na misudzuluso yo fhambanaho, nahone tshikirini tsha luṱingo tshiṱuku. Ndi ngazwo ndingo ya tshitendeledzi ya Helibrain i tshi vhulunga mvelelo yaṋu ya khwine nga thungo ya u shumisa muthetshe na mbeu, nahone ya vhambedza mvelelo fhedzi vhukati ha tshishumiswa tshithihi tsha u ṅwala.

Ni ola hani tshitendeledzi tsho linganaho ni si na khompassi?

Kumedzani tshanḓa tshaṋu vhukati, ni shumise munwe muṱuku kana tshanḓa sa tshithu tsha u monisa ngatsho, ni monise bammbiri kana tshanḓa tshaṋu. Musi ni tshi ola nga tshanḓa, olani zwitendeledzi zwihulwane nga tshanḓa tshoṱhe nahone nga luvhilo lwo eḓanaho. Nḓowetshedzani kha ndingo ni sedze mivhala ya mutalo waṋu uri ni vhone hune na pambuwa hone.

Ndingo ya tshitendeledzi ya Helibrain ndi ya mahala zwa vhukuma?

Ee. Ndingo na mvelelo yaṋu yo fhelelaho ndi zwa mahala: a hu ṱoḓei u ḓiṅwalisa, imeili kana u badela. Helibrain i wana tshelede kha app yayo, ine ya vha na pulane ya mahala na dziṅwe pulane dza u badela; a ni ṱoḓi app uri ni ite ndingo.

Ndingo dzi elanaho

How this test works

This game tests how steady and even your hand is. Put your finger or the mouse button down and draw one circle around the dot in a single stroke. When you lift, we fit the best circle to your line and measure how far your line strays from it, on average. Your roundness score is 100% minus that average wobble, so a line that wobbles by 2% scores 98%. Motor-control labs have measured hand-drawn curves like this since the 1980s.
