I worked with my 9 year old grandson on his spelling words yesterday.
His h’s, r’s and n’s are impossible to differentiate.
He has problems with a few other letters as well.
I would love to see one of these machines or workers could make out his hand writing.
I assume the system uses a large database comprising individual handwritten character/word samples.
Then it is sort of a high tech Wheel of Fortune sans Vanna White to figure out the rest. Ulimately, some may have to be routed to a human.
IIRC, the USPS deserves kudos for developing ICR (the handwriting version of OCR that reads print).
One of my failures as I’ve been getting older is in handwriting, especially since nowadays, most of my “writing” is done with a computer keyboard.
My printing used to be as neat as a pin, and I had great cursive. Nowadays, I’m lucky if I can write a check without any mistakes, and my signature is more scribbly than before. And my print would probably put me in good company with doctors writing prescriptions.
