Welcome to Handwriting ➦ Text, Scratch's first comparison based handwriting recognition system. This project is still very early in development so there may be several accuracy errors. --------------------------------------------------------------- Instructions: Please write one of the letters below in capitalized form as big as possible in the white rectangle and press space for the recognizer to scan your letter. If the scanner guesses wrong, click the "Wrong" button and type in the letter you were trying to draw and the scanner will learn from its mistake. If the scanner got the guess correct, but it was less than 90% sure, click the "Correct" button so the scanner knows that it was correct and it can guess with the same accuracy next time! Unfortunately, the scan time to recognize a letter takes about five seconds do to unoptimized scanning techniques. This will be fixed in the future! --------------------------------------------------------------- Supported characters: • All uppercase letters • All numbers • ! • @ • $ • . • ? --------------------------------------------------------------- How it works: This project compares your drawing to a single mapping of the letter in a pre-made set and takes note of how close your drawing came to matching each mapping of a letter as a percentage. The project then filters out the highest percentage guess and states it to the user along with the percentage of certainty itself. --------------------------------------------------------------- Developer notes (concise): • List based tri-stage text recognition • Embedded character mappings (.ecm) • 120 Point data capture • 4.008 Second mean rescan • Pen: True | Clone: True | Stamp: False • 20KB Pre-baked data set ---------------------------------------------------------------
