HOW IT WORKS & METHODOLOGY

UNDERSTANDING THE MATH, FORMULAS & CALCULATION ENGINE

01

One Continuous Stroke

Click and drag on desktop or draw with your finger/stylus on mobile in a single unbroken loop.

02

Centroid & Radius Variance Algorithm

We calculate the polygon centroid and measure radial variance across 360 degrees to compute mathematical circularity.

03

Accuracy Percentage

Receive an instant score from 0% to 100% with color-coded visual deviation indicators.

FREQUENTLY ASKED QUESTIONS

EVERYTHING YOU NEED TO KNOW ABOUT THIS EXPERIMENT

Q1.How is circularity accuracy calculated mathematically?↓
The algorithm computes the geometric center (centroid) of your drawn path, calculates the mean radius, and evaluates root-mean-square deviation (RMSD) across all perimeter points.
Q2.What is considered a world-class score?↓
Scores above 90% are very good, above 95% are exceptional, and reaching 98%+ freehand requires elite motor control and precision.
