Handwriting Efficiency Lab

Controlled writing-speed experiments that make stroke structure, pen-up travel, and total movement visible.

What this lab measures

A writing model is more than a font label.

Each experiment holds the sample text and renderer settings constant, then measures how stroke connections change completion time, characters per minute, paper-trail length, air travel, and total movement.

The videos use extracted real stroke-order paths rendered deterministically on canvas. They are original simulations, not AI-generated handwriting.

The protocol

  1. 01Use a fixed sample and document its case mix.
  2. 02Calibrate writing speed from the lowercase n reference.
  3. 03Model pen lifts explicitly instead of hiding them.
  4. 04Report metric-specific results and limitations.

The lab compares writing-model structure under defined renderer settings. It does not rank fonts for every writer, prove that cursive is always faster, or replace a legibility or learning study.
