Panon ya basaen so puntos mo

  • Kabilugan: 100% a nabawas so kaarawi na linya mo ed pinakamatalinong bilog, bilang average tan kasenggutan na radius na bilog. No manggulo so linya na 2% bilang average, 98% so puntos na.
  • Saray kolor na linya mo: berde no say linya et ed ibabaw na bilog, duman ed dilaw, anggad pula no marayo ya manliko.
  • Say putol-putol ya bilog: say pinakamatalinong bilog para ed ginuhit mo. No mas asingger so linya mo ed bilog, mas atagey so puntos.
  • Pinakamataas mo: say pinakamataas ya puntos mo ed say browser ya us-usaren mo, walay bukod para ed touchscreen tan para ed mouse, ta man-iba so panagguhit gamit so dalirem tan mouse.
  • Direksyon: clockwise odino counterclockwise. Kaaduan ed saray totoo ed US et man-guhit na counterclockwise; ed Japan, kaaduan et clockwise [1].

Mampalugar ka kaya na gumuhit na perpekto ya bilog gamit so ima?

Ag-oyan ya perpekto, balet asinggeran. Say bilog ya ginuhit na ima et kanayon ya walay anggad-angga ya paggulo, ta man-inandian tan man-atey so panag-igagalaw na ima bayat ya manliko ed kurba [2]. Ed pamantayan mi, no manggulo so linya ed bilog na 2% bilang average, 98% so puntos na. Say sikat ya viral na bilog na Canadian ya managbangat na matematika et natantya ya 99.7% so kabilugan na segun ed panon na panagtantiya na sakey ya blogger [3].

Madali ya amta

  • Man-agad so direksyon ed lugar ya inluwal ka: ed mga 50,000 ya drawing na saray totoo ed US ed laro na Quick, Draw! na Google, 86% na saray bilog et counterclockwise; ed mga 800 ya drawing ed Japan, 80% et clockwise [1].
  • Apektado na ugali ed panagsulat: mas kaaduan so panagguhit na clockwise na saray anak ed Japan kabang man-eskwela da, tan mas counterclockwise na saray anak ed US; say saray anak ed Japan ya man-agna ed US et mas diket so clockwise ya ginuhit da [4].
  • Say tuntunin na kaplesan na ima: mas mabagal so ima ed mas masikip ya kurba tan mas mabilis ed mas patag ya parte (say "two-thirds power law"). Ed bilog, kapara so kurba ed amin ya lugar, kaya ipapakit na tuntunin ya pare-pareho so kaplesan [2][5].
  • Say "kampeon na mundo": say managbangat na matematika ed viral ya bidyo na bilog et kinun na diad impanunan ya birbiran la so titulo na "kampeon na panagguhit na bilog gamit so ima ed interon mundo" ya imbaga to ed klase to [6].
  • Ag-ilalo na tanda na salun-at: say ideya ed dekada 1970 ya tanda na sakit ed isip so panagguhit na clockwise, et agnapatalosan ed saray sinumayun ya panag-aral [7].

Panon ya gawa so sukimat na bilog

  1. Gumuhit. Ipalapag so dalirem mo (odino pindutan na mouse) ed anton labay mo tan gumuhit na sakey ya bilog ed arum na punto, gamit so sakey ya galaw.
  2. Nengnengen bayat ya gawa. No nagawa mo la so saray arum na parte na bilog, ipanengneng so kabilugan ed tengnga tan manbaliw so kolor na linya.
  3. Ipaalsa. No nalpas ka, ipanengneng so pinakamatalinong bilog a putol-putol tan bilang so puntos na ginuhit mo.

Para bilangen, kailangan ya lumabas so drawing na anggapo minos 320° ed bilog, onsabi ya asinggeran ed pinangirugian, dakel so laki na (say radius et anggapo minos 15% na kalawa na lugar ya panagguhitan) tan aglumabay na 30 segundo. Sakey labat ya liko, paki. Ibagay mi so bilog ed saray punto gamit so least squares, tan bilangen so average ya distansya da ed bilog. Saray bilog na dalirem et ikumpara labat ed arum ya bilog na dalirem.

Akin ya mabager so panagguhit na perpekto ya bilog?

No mangguhit na bilog, kailangan ya mankakasakey so abaga, siko, pulso tan saray dalirem mo, kabang tuloy-tuloy ya manbaliw so direksyon na galaw. Natural ya man-atey tan man-inandian so ima mo a kasumpa na kurba [2], tan kada panagbaliw na kaplesan et pagkakataon ya manliko ed luar odino uneg. Ed cellphone, pagtatakpan na dalirem mo so linya ya ginuguhit mo. Igalaw na mouse so interon taklay, saray bilog ya iguhit gamit mouse tan dalirem et balet magmaliw ya agkapara so puntos da.

Saray sipan para mas bilog so drawing

  • Gumuhit na mas baleg tan usaren so interon taklay. Mas manggulo so diket ya bilog ya dalirem labat so mangguhit.
  • Pare-pareho so kaplesan. Agmabagal unay: no mabagal unay so panagguhit et mas mankigkig.
  • Nengnengen so punto ed tengnga, agso linya. Say trabaho et panamegley na parehong distansya ed tengnga.
  • Maong ya ipasara so linya. Adu so bilog ya nabawasan na puntos ed pananguman, no manmamadali so totoo ya manengneng ed irug na linya.

Antoy maipapanengneng na sukimat yaan tan antoy agto maipapanengneng

Say sukimat na bilog et makagalaw ya sukimat na kontrol na ima. Man-agad so puntos mo ed gamit mo, laki na screen, no dalirem, pluma odino mouse so usaren mo, tan ed panagsanay. Ag-ya sukimat ed medisina odino sukimat na panagkigkig; arum ya panagguhit so usaren na doktor, singa spiral [8]. Anggapo ibabaga ed salun-at mo so direksyon na panagguhit.

Kanayon ya iyasal ya saludos

Mampalugar so panagguhit na perpekto ya bilog gamit so ima?

Anggapo bilog ya ginuhit na ima so perpekto ya bilog, balet asinggeran na saray totoo. Ed sukimat na bilog na Helibrain, say kabilugan et 100% a nabawas so average ya paggulo na linya mo, kaya no manggulo na 2% so linya bilang average, 98% so puntos. Para onsabi ed eksaktong 100%, kailangan ya anggapo pulos so paggulo na linya.

Kaaduan ed saray totoo et man-guhit na bilog ya clockwise odino counterclockwise?

Agad ed lugar ya inluwal ka. Ed saray drawing na Quick, Draw! na Google, 86% ed mga 50,000 ya bilog na saray totoo ed US et counterclockwise, kabang 80% ed mga 800 ya bilog ed Japan et clockwise [1]. Mas importante so ugali ed panagsulat nen say anto ya ima so usaren mo [4].

Panon ya bilangen so puntos na kabilugan ko?

Ibagay na sukimat na bilog na Helibrain so pinakamatalinong bilog ed amin ya punto na linya mo (least-squares fit), kalpas et sukaten no kasano ya arawi so kada punto ed bilog. Say average ya distansya, a kasenggutan na radius na bilog, so paggulo na linya mo; say kabilugan et 100% a nabawas so paggulo. Pababaen na oval, nayupi ya parte odino panagsalimbengan so puntos.

Akin ya agkapara so puntos ko ed cellphone tan computer?

Man-iba so saray galaw tan uneg ya gamit no dalirem tan mouse so usaren, tan mas diket so screen na cellphone. Kaya walay bukod ya pinakamataas ya puntos ed sukimat na bilog na Helibrain para ed touchscreen tan para ed mouse, tan ikumpara labat so resulta ed kapara ya klase na gamit.

Panon ya mangguhit na perpekto ya bilog anggapo compass?

Ipatengnga so ima mo ed tengnga, gamit so diket ya dalirem odino pulso bilang panagsuportaan, tan pihiten so papel odino taklay mo ed aglawas na ima. No freehand, gumuhit na baleg ya bilog gamit so interon taklay mo, ya pare-pareho so kaplesan. Managsanay ed sukimat tan nengnengen so saray kolor na linya mo para amtaen no iner ka manliko.

Libre talaga so sukimat na bilog na Helibrain?

Wen. Libre so sukimat tan interon resulta mo: angga'y agmanparehistro, angga'y ag-email, angga'y agbayad. Manalako na kuarta so Helibrain ed app to, ya walay libreng plano tan bayadan ya plano; agmo kailangan so app para mangusar ed sukimat.

Saray kaaruman ya sukimat

Nengnengen amin ya 43 libre ya sukimat na isip

Labay mo irayar inaldaw? Say app na Helibrain (ed Ingles ni laeng) et walaan na libre tan bayad ya plano.

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.
